INCORPORATION BY REFERENCE

U.S. Provisional Application No. 63/725,069, filed Nov. 26, 2024, U.S. Provisional Application No. 63/831,430, filed Jun. 27, 2025, are specifically incorporated by reference herein as if set forth in their entireties.

TECHNICAL FIELD

In one aspect, the present disclosure is directed to dispensing systems, assemblies, dispensers, and methods of controlling such dispensing systems, assemblies and dispensers to dispense fluid or sheet materials, and more particularly, is directed to dispensing systems, assemblies and dispensers including a control system in communication with or including a power management system for selectively activating components and/or assemblies of the at least one dispenser to minimize power usage and provide for compilation and communication of information regarding the at least one dispenser. Other aspects are also described.

BACKGROUND

Dispensers for dispensing fluid or sheet materials, such for dispensing sheet materials such as tissue paper, paper towels, and other paper products, as well as for dispensing fluid materials or liquids like soaps, scrubs, and hand sanitizers, are commonly used in hospitals, restrooms, homes, and various other facilities for sanitary and hygiene purposes and to help control the amount of paper or fluids dispensed. Many facilities such as hospitals have strict health and safety protocols that require personnel to diligently wash their hands and use hand sanitizer, etc., though tracking such use can be difficult. Additionally, many types of automated dispensers typically are maintained in a substantially active state, continuously looking for the next user and ready to dispense an amount of paper or fluid. However, by remining in a substantially always active or powered-on state, the steady state power consumption of such dispensers can remain at a generally constant high level, which can lead to increased operational costs and in cases where the dispensers are powered by batteries, appreciably shorter battery life.

Therefore, it can be seen that there is a need for dispensing systems, assemblies, dispensers, and methods of operation thereof that can provide increased control of power consumption without disrupting use of the dispensing systems, and which can provide for monitoring, collection and communication of information regarding the use and status of the dispensing systems, assemblies and dispensers The present disclosure addresses these and other related and unrelated issues in the art.

SUMMARY

In one aspect, the present disclosure is directed to dispensing systems, assemblies, dispensers, and methods of operation and assembly thereof. In embodiments, the dispensing systems can include at least one dispenser or dispensing assembly, and in some embodiments, can include a series of dispensers or dispensing assemblies that can be in communication with one another. In embodiments, each dispenser of the dispensing systems generally can be operable for dispensing selected amounts of a sheet material, for example, paper products, including paper towels, tissue, napkins, etc., and/or for dispensing fluid materials or liquids, e.g., liquid soap, hand sanitizers, gels, etc.

In various embodiments, the dispensing systems can be used in a variety of different environments, including, without limitation, use in a residential setting (e.g., in a bathroom in a person's home), as well as in commercial locations (e.g., in bathrooms and/or kitchens of restaurants, large venues such as arenas, airports, etc.) and other locations such as in hospitals, schools, etc. In embodiments, each dispenser of the dispensing systems can include a dispenser housing having a dispensing mechanism and a supply of a fluid or a sheet material to be dispensed, which can be dispensed in metered, predetermined amounts during each dispensing operation or cycle. In embodiments, the housing can be a metal, plastic, or other, similar rigid material, and in some embodiments, can be treated with an antimicrobial agent.

In an example construction, the dispenser (or dispensers in embodiments where the dispensing systems include a series of dispensers) can comprise a sheet material dispenser having one or more rolls of a sheet material (e.g., tissue, paper towels, etc.), a feed roller that can be driven manually or by a motor to feed a predetermined amount of sheet material during a dispensing operation, and, in embodiments, one or more pressing rollers configured to urge the sheet material against the feed roller such that the sheet material is pulled or drawn therebetween during a dispensing operation. In another construction, the dispenser can include a liquid dispenser with a supply chamber or reservoir containing a fluid, e.g., liquid soap, hand sanitizer, etc., one or more nozzles or other discharge outlets for dispensing the liquid to users (e.g., upon activation of one or more sensors or other activation mechanisms), and a pumping mechanism for directing the fluid from the supply chamber to a discharge outlet(s).

In embodiments, the dispenser, or, in embodiments such as where the dispensing system includes a series of dispensers, each dispenser of the dispensing system further can include a power supply and a power management system in communication with a dispensing assembly. In embodiments, the dispensing assembly can include a dispensing mechanism, at least one activation sensor, and a control system.

In embodiments, the dispensing mechanism can include a feed roller that can be driven by a drive assembly that, in embodiments, can include a motor or other actuator, or can be manually operable to drive the rotation of the feed roller, and one or more pressing rollers. The dispensing mechanism can communicate with the control system and/or the at least one activation sensor and generally will be configured to dispense a selected amount of a fluid or sheet material in response to an activation or initiation signal.

The at least one activation sensor is configured to detect and be activated by a user to initiate dispensing of the selected amount of the fluid or sheet material. For example, when a user's hand is within a close enough proximity to the activation sensor, or, in some embodiments, when the user engages the activation sensor such as by placing their hand within a detection zone for the activation sensor, the activation sensor can send an activation signal to the control system to initiate a dispensing operation. In embodiments, the detection zone can be located within a recessed area or pocket.

In embodiments, the control system will be in communication with a power source and with various components of the dispenser, such as the dispensing mechanism, the at least one activation sensor, and the power management system, which can control the powering on/off of the control system and the other components of the dispenser. In embodiments, the control system also can be in communication with and/or control other components such as a display, communications system, and other features of the dispenser.

In addition, in some embodiments, the dispenser can include one or more monitoring sensors configured to monitor the dispensing system, usage of the dispenser, the occurrence of fault conditions such as low power, low or no supply, transmissions from identifying badges carried by individuals, etc. For example, in some embodiments, the dispenser can include a detector configured to monitor/measure a level or amount of a sheet material or fluid remaining in a supply and communicate this to the control system. In embodiments, if the level is determined to be below a threshold level or amount, the control system can generate an alert or otherwise signal a low/no supply condition to facilitate replacement of the supply when needed (so as to not waste unused fluid or sheet material within the supply) and without undue delay.

Still further in embodiments, the dispenser can include a display that can include indicators such as a screen or lights, and a communication system. In embodiments, the communication system can include a transmitter that can be linked to or included as part of the control system (or, in embodiments, multiple transmitters linked to various components or assemblies of the dispenser). The transmitter generally will be configured to transmit information/data such as dispenser usage information, tracking information regarding individuals' use of the dispenser (or no use), fault conditions such as a low power or low/no supply of material (e.g., paper or fluid material), or other information, to a server, network, mobile application, facility control, or combinations thereof.

In embodiments, the power management system is in communication with the power supply and the operative components of the dispenser, such as the controller of the control system, dispensing assembly, including, for example, the dispensing mechanism (e.g., motors, sensors, etc.), the at least one activation sensor, and/or other components, and includes at least one passive infrared radiation sensor. The at least one passive infrared radiation (PIR) sensor is configured to capture infrared radiation of one or more individuals within a prescribed detection range, area, or zone.

In embodiments, the control system can be kept in a powered down state (e.g., disconnected from the power supply) if the presence of a user within the prescribed detection range, area, or zone is not detected by the at least one PIR sensor, and can be reconnected to the power supply or otherwise placed in a powered-on state when the presence of one or more individuals is detected within the prescribed detection range, area, or zone For example, the power management system can include at least one PIR sensor and an associated controller (e.g., the at least one PIR sensor can have its own controller) that can include programming to place the control system in a powered down state (e.g., after a prescribed time, or other event).

In embodiments, the power management system can include or can be in communication with a switch or other connection mechanism configured to disconnect or decouple one or more of the operative components of the dispenser, such as, for example, the dispensing assembly, including the control system, activation sensor, dispensing mechanism, and other components, from the power source, such that the primary operative components of the dispenser, with the exception of one or more PIR sensors, are not drawing power when not in operation. When a user enters the detection area or zone covered by the at least one PIR sensor, the power management system can engage the switch to enable power from the power source to be supplied to one or more components of the dispensing assembly.

For example, in embodiments, when infrared radiation from the user is detected by the at least one PIR sensor, the power management system can initially enable the connection of the activation sensor(s) to the power source, while maintaining other components such as the dispensing mechanism and the control system of the dispenser to remain disconnected from the power supply and/or otherwise remain in a substantially powered down state. The control system, dispensing mechanism and other components can remain in their powered-down/off state, drawing minimal to no power from the power source, until the activation sensor is triggered, such as by detection of motion by an individual or user. In embodiments, if the activation sensor is not triggered/activated (e.g., no activation signal is generated within a preset time), the power management system can shut down power to the activation sensor, without the remaining components for the dispensing assembly and the dispensing system overall having to draw power.

If the activation sensor is engaged by the user, one or more activation signals can be sent, either directly to the control system, or initially to the power management system, to cause the controller of the control system and the dispensing mechanism to be connected to the power supply and/or otherwise be placed in a powered-on state. Once in the powered-on state, the controller is configured to activate the dispensing mechanism to dispense the selected amount of the fluid or sheet material upon receipt of the one or more activation signals from the at least one activation sensor.

Thereafter, the power management system is configured to disconnect the control system, the at least one activation sensor, and the dispensing mechanism from the power source and connect the at least one activation sensor to the power source when the at least one PIR sensor does not capture infrared radiation of one or more individuals within the prescribed detection range, area, or zone. For example, after a prescribed period of time with no detection of infrared radiation by the PIR sensor, the operative components of the dispenser can be disconnected from the power supply. In addition, in embodiments, the control system and the dispensing mechanism, as well as other operative components such as a transmitter and display, etc. can remain disconnected from the power source until the at least one activation sensor has detected the user.

In various embodiments, the at least one PIR sensor of the power management system, the control system (e.g., a controller of the dispenser), the at least one activation sensor, and the dispensing mechanism, as well as other operative components of the dispenser/dispensing system, can include a smart architecture, with each having their own associated processor(s) or CPU, which can be configured and/or include programing or instructions enabling each of such operative components to perform its functions independently of the others. In addition, in embodiments, the at least one PIR sensor of the power management system, the control system, at least one activation sensor, and the dispensing mechanism, and/or other operative components of the dispenser/dispensing system, can comprise changeable or “plug-and-play” components, enabling such components, and, in embodiments, the processors thereof, to be removed and replaced and/or adapted to update the dispenser, such as to accommodate different or changing usage conditions.

In another aspect, the dispensing system can comprise a series of dispensers arranged throughout out a selected area (e.g., a bathroom such as in an airport, etc.). In embodiments, each of the dispensers can be independently operable. In some embodiments, the series of dispensers can include a lead dispenser and a plurality of drone dispensers. The lead dispenser can include a power management system and a control system that can be configured for controlling one or more operations of the lead dispenser, and at least partially control operation of one or more of the drone or other dispensers. For example, the lead dispenser can be positioned at a central or initial location selected detect the user initially entering into the detection area space, or zone, and when it detects the user, can turn wake up, or otherwise cause the power management systems of the one or more drone or other dispensers to be placed in a powered-on or active state connected to a power supply, while the dispensing assemblies of such dispensers remain in a substantially powered-off state, for example, being disconnected from the power supply. Thereafter, each drone or other dispenser can be operated independently to feed a fluid or sheet material only when activated, while the dispensing assemblies thereof otherwise remain in the substantially powered-off state.

In embodiments, the dispensing system can also include, be linked to, or can be part of a network through which various dispensers, for example, one or more drone dispensers and a lead dispenser within an area or facility, can communicate with each other and with a central server, facility management system, to the cloud, or other recipient (e.g., via Wi-Fi or other network connection). In embodiments, such communications generally will be provided wirelessly.

For example, in embodiments, where the dispensing system includes a central, primary or lead dispenser and one or more secondary or drone dispensers, the lead dispenser can be configured to communicate information related to the lead dispenser and/or information received from the plurality of drone dispensers to other recipients, such as to a central server, facility management or building control system, manager, to the cloud, etc . . . via the network. In some embodiments, the primary or lead dispenser, or each individual dispenser, including the primary or lead dispenser and secondary or drone dispensers, can be configured to communicate information such as alerts for low supplies of sheet materials or fluids, jams, low power, or various other operating conditions thereof, to a central server, facility management or building control system, manager, to the cloud, etc.

In embodiments, the dispensing system, including each dispenser thereof, also can include one or more transmitters configured to transmit and/or receive signals for exchanging information and transmitting data (e.g., dispenser usage, supply levels, etc.), alerts, and/or other notifications from one or more dispensers to the lead dispenser (e.g., if the one or more drone dispensers are experiencing an error condition, a low power condition, and/or a low supply condition), and/or to other recipients. In embodiments, some of the dispensers can be configured to send messages to a lead or primary receiving dispenser, which can then send an information packet including data/information collected/received from one or more dispensers to the central server, facility management or building control system, manager, to the cloud, etc., (e.g., wirelessly such as by Bluetooth® or Wi-Fi); while is other embodiments, each dispenser can individually transmit its information, in addition to or without sending such information to a lead or primary receiving dispenser.

In embodiments, the dispensers can be configured to send messages such as alerts, dispenser operation and supply information, refill reminders, etc., at predetermined times. For example, in some embodiments, the dispensers can be configured to transmit messages such as alerts and other information to the central server, facility management or building control system, manager, to the cloud, etc. when the dispenser is activated. Thus, when the dispenser is in a powered down state in which its controller is powered off, no messages may be sent, conserving power since the dispenser can remain disconnected from Wi-Fi until a dispensing operation is initiated, has been completed, and/or is in progress. In addition, once the message has been sent, the network connection (e.g., Wi-Fi) of the dispenser can be closed, for example, when the power management system disconnects the control system, the network connection also can be disconnected, including powering down or off the transmitter and/or receiver.

In still other still other embodiments, if, for example, an alert indicating an error or fault condition such as a jam, low or no supply condition, has been generated, the dispenser can further be configured to connect to the network and transmit an update to indicate if/when the fault condition has been cleared.

In addition, in various embodiments, the control system of the dispenser can include one or more transmitters and/or receivers configured to at least periodically monitor the selected activation area or zone within a determined proximity of the dispenser to detect signals being transmitted by transmitters carried by individuals. For example, the dispenser can be part of a dispensing system located within a hospital or other, similar facility in which compliance with certain health and safety protocols (e.g., requirements for doctors, nurses and other personnel to perform handwashing and other sanitizing operations upon entering and/or leaving a patient's room). In some such instances, the dispensing system can communicate with or be integrated with or as a part of a compliance system for the facility.

In embodiments, the control system can look for or request identification signals from an individual's badge and multiple points/times within a dispensing operation. For example, when the control system of the dispenser initially receives a first signal from the individual's badge, it can identify the presence of that particular individual and proximity to the dispenser. The control system can then search for a second identification signal in conjunction with the activation of the dispensing mechanism, and search for an additional identification signal from the individual's badge (e.g., a third signal) upon completion of the dispensing operation. If the additional (e.g. one or more second and/or third signals) identification signals are not received and/or a dispensing operation is not initiated after the first identification signal from the individual's badge is detected, the control system can generate a noncompliance record indicating that the individual failed to use the dispenser. In embodiments, such a noncompliance record can be transmitted together with the identification of the individual associated with a detected badge to server, network, mobile application, facility control, or other system, for tracking and monitoring of movements of individuals throughout the facility and their compliance with health and safety protocols.

Still further, in embodiments, the power management system of a dispenser including such a system can be configured to selectively power up the dispenser to enable transmission of messages such as alerts, status messages, etc. at selected time intervals. For example, in embodiments, the power management system (e.g., at least the PIR sensor) can include a processor or CPU that, in addition to programming/instructions for controlling the connection of the operative elements of the dispenser to the power supply, can include programming/instructions to turn on the transmitter and control system of the dispenser, with or without powering on the activation sensor(s), dispensing mechanism or other components, at least for a time sufficient to send the message. Thereafter, in embodiments, the power management system can power down (e.g., disconnect from the power supply) the control system and transmitter, such as, for example, upon receiving a confirmation from the recipient of the message (e.g., a central server, facility management or building control system, manager, to the cloud, etc.) that the message has been received, or after a selected time period, which can allow for additional communications between the dispensers and the recipient.

In still other embodiments, if, for example, an alert indicating a fault condition such as a low supply condition, has been generated, the dispensers can further be configured to connect to the network and transmit an update to indicate if/when the fault condition has been cleared.

DETAILED DESCRIPTION

The present disclosure relates to dispensing systems and methods of operation/use thereof, and in embodiments, to dispensing systems including dispensers configured to selectively dispense sheet materials or fluid or liquid materials. In embodiments, the fluid or liquid materials can comprise soaps, sanitizers, and/or other fluids or liquids that can be provided and stored or contained within a supply, such as a container that can loaded into the dispenser and from which the fluid can be and selectively drawn and dispensed. In other embodiments, sheet materials such as, without limitation, paper towels, tissues and other, similar materials, can be loaded into the dispenser in rolls, with the sheet materials being progressively drawn from the rolls during a dispensing operation.

The dispensing systems, dispensers and various features, assemblies and mechanisms thereof, as well as various methods of operating such dispensing systems, dispensers, assemblies and mechanisms for dispensing fluid or sheet materials according to the present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and their previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this disclosure is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, and, as such, can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

The following description of the dispensing systems, dispensers and methods is provided as an enabling teaching of such dispensing systems, dispensers and methods according to the principles of the present disclosure. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects of the disclosure described herein, while still obtaining the beneficial results of the dispensing systems, dispensers and methods of the present disclosure. It will also be apparent that some of the desired benefits of the dispensing systems, dispensers and methods of the present disclosure can be obtained by selecting some of the features of the present invention without utilizing other features. Accordingly, those who work in the art will recognize that many modifications and adaptations to the dispensing systems, dispensers and methods described herein are possible and can even be desirable in certain circumstances and are a part of the dispensing systems, dispensers and methods of the present disclosure. Thus, the following description is provided as illustrative of the principles of the dispensing systems, dispensers and methods of the present disclosure and not in limitation thereof.

As used throughout, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a chamber” can include two or more such chambers unless the context indicates otherwise.

Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

The word “or” as used herein means any one member of a particular list and also includes any combination of members of that list. Further, one should note that conditional language, such as, among others, “can,” “could,” “might,” or “can,” unless specifically stated otherwise, or otherwise understood within the context as used, is generally intended to convey that certain aspects include, while other aspects do not include, certain features, elements and/or steps. Thus, such conditional language is not generally intended to imply that features, elements and/or steps are in any way required for one or more particular aspects or that one or more particular aspects necessarily include logic for deciding, with or without user input or prompting, whether these features, elements and/or steps are included or are to be performed in any particular embodiment.

The phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. As used herein, the term “plurality” refers to two or more items or components. The terms “comprising,” “including,” “carrying,” “having,” “containing,” and “involving,” whether in the written description or the claims and the like, are open-ended terms, i.e., to mean “including but not limited to.” Thus, the use of such terms is meant to encompass the items listed thereafter, and equivalents thereof, as well as additional items. Only the transitional phrases “consisting of” and “consisting essentially of,” are closed or semi-closed transitional phrases, respectively, with respect to any claims. Use of ordinal terms such as “first,” “second,” “third,” and the like in the claims to modify a claim element does not by itself connote any priority, precedence, or order of one claim element over another or the temporal order in which acts of a method are performed but are used merely as labels to distinguish one claim element having a certain name from another element having a same name (but for use of the ordinal term) to distinguish claim elements.

Disclosed are components that can be used to perform the disclosed methods and systems. These and other components are disclosed herein, and it is understood that when combinations, subsets, interactions, groups, etc. of these components are disclosed that while specific reference to each various individual and collective combinations and permutation of these cannot be explicitly disclosed, each is specifically contemplated and described herein, for all methods and systems. This applies to all aspects of this application including, but not limited to, steps in the disclosed methods. Thus, if there are additional steps that can be performed, it is understood that each of these additional steps can be performed with any specific embodiment or combination of embodiments of the disclosed methods.

The present methods and systems can be understood more readily by reference to the following detailed description of preferred embodiments and the examples included therein and to the Figures and their previous and following description.

As generally illustrated in FIGS. 1A-9E embodiments of the present disclosure are directed to dispensing systems 500 that include at least one dispenser 10. In embodiments, the dispenser generally can comprise an automated dispenser 10 for feeding or dispensing a selected material. For example, in some embodiments, the dispenser can be configured to dispense a sheet material 12, which, in embodiments, can include a dispenser 10 adapted to dispense a sheet material from a single supply as illustrated in FIGS. 1A-1C, or from multiple (e.g., two) supplies of sheet materials such as illustrated in FIGS. 2B-2G. In other embodiments, the dispenser can comprise a fluid dispenser 300 configured for dispensing fluid or liquid materials.

In addition, in embodiments, such as shown in FIGS. 7A-7D, the dispensing system 500 can include one or more dispensers. For example, in some embodiments, such as illustrated in FIG. 7D, the dispensing system 500 can include a plurality of dispensers that can be located at different selected locations within a facility. In embodiments, the dispensers of the dispensing system can be located, such as, for example, within bathrooms, patient rooms, personnel stations, etc. of a facility such as a hospital, clinic or other, similar facility. In other embodiments, the dispensers of the dispensing system can be arranged in sets or series that can include a lead dispenser and one or more drone dispensers that communicate with the lead dispenser as illustrated in FIG. 7D.

In embodiments, the dispenser may be recessed into a wall with a lower profile or configuration to help reduce a footprint of the dispenser or can be mounted to a wall. The dispenser may dispense rolled sheet material for a user to dry an object or in a commercial setting, dispense material for wrapping products such as packages, meat, etc. where rolled material is needed; or can be used to dispense liquids or fluid materials such as liquid soap, hand sanitizer, shampoo, etc. The dispenser housing can further include a housing 16 that can include or can be formed from an antimicrobial plastic or composite material or can be formed from a metal or composite material treated with an antimicrobial coating on all touchable surfaces.

In one aspect, as shown in FIGS. 1A-2G, the dispenser 10 can be configured to dispense various types of sheet materials 12 including paper sheet materials such as towels, tissue, napkins, etc. In embodiments, the dispenser 10 generally will include a dispensing mechanism 15 including a driven roller drive assembly 14 mounted or otherwise disposed within a dispenser housing 16 and operable to dispense prescribed amounts/lengths of sheet material. For example, upon activating the dispenser 10, the feed roller drive assembly 14 is engaged and operates to drive or cause rotation of a drive spindle or feed roller 18 (FIG. 1C). In addition, in some embodiments, the dispensing mechanism 15 can be incorporated into a housing or a cassette 17 that can be replaceable mounted within the dispenser housing.

FIGS. 1A-1C show an example embodiment of a sheet material dispenser 10 configured to dispense a sheet material 12 from a single supply 20 of sheet material 12. For example, the dispenser of FIGS. 1A-1C can be configured to dispense tissue paper from a supply roll 20 of tissue paper. In other embodiments, such as shown in FIGS. 2B, 2C, and 2E-2G, the dispenser 10 can be configured to dispense sheet materials 12 from two or more supply rolls 20.

It further should be appreciated that the dispenser 10 described herein should not be considered to be limited to any particular style, configuration, or intended use, or to a particular type of sheet material. For example, the dispenser 10 may be operable to dispense paper towels, toilet tissue, or other similar paper or sheet materials, including dispensing or feeding non-perforated and/or perforated sheet materials. In addition, the dispensers and dispensing system can be used in a variety of different environments, including, without limitation, use in a residential setting (e.g., in a bathroom in a person's home), as well as in commercial locations (e.g., in bathrooms and/or kitchens of restaurants, large venues such as arenas, airports, etc., and other locations such as in hospitals, schools, etc.).

In embodiments, the feed roller drive assembly 14 of the dispensing mechanism 15 of the dispenser 10 can include at least one feed roller 18 and one or more pressing rolls 19. The rotation of the feed roller 18 in turn pulls the sheet material 12 from a supply of sheet material supply 20 for feeding a predetermined, prescribed, measured or selected amount or length L (e.g., a 10″-12″ or other desired length) of the sheet material 12 along a conveying or feed path P (FIG. 1B) from the roll or the sheet material supply 20 of the sheet material 12 through and out of a discharge, such as a discharge chute 22 or other suitable opening provided/defined in the dispenser housing 16 of the dispenser 10, as is generally indicated in FIG. 1C.

The feed roller drive assembly 14 can be activated and driven/rotated to pull and feed the sheet material 12 from the sheet material supply 20 to and through the discharge chute 22 under control of a control system 506 of the dispenser 10. Example embodiments of control systems 506 for the dispensers 10 of the dispensing system 500, which will be configured for operating their dispensers 10, and in some embodiments, can be configured to communicate with and control operation of multiple dispensers of a dispensing system, are generally shown in FIGS. 7A-7D.

For example, in embodiments such as shown in FIGS. 7A-7C, each dispenser can include a control system 506 including a controller 514 that can comprise one or more processors, such as a microprocessor, CPU, etc., a memory 516, and computer programming stored in the memory 516 and executed by the controller 514 for control of the feed roller drive assembly 14 to feed the selected or desired length of sheet material and to monitor the dispenser 10 and components such as the supply of sheet material and usage/operation of the dispenser. The control system 506 further will be in communication with, and will receive a plurality of signals, from at least one activation sensor 414 of an activation system 400, which, in embodiments, can comprise at least one activation sensor or an array or series of activation sensors configured to detect the presence of an individual or user within a selected activation zone, proximity of range and generate an activation signal to initiate dispensing of the sheet material or other material being dispensed.

The activation system 400 can include an activation sensor assembly 401, which, in embodiments, can include one or more activation sensors 414, which, in various embodiments, can comprise various type sensors or detectors, for example, including an adjustable proximity sensor that can be configured/adjusted to detect the presence of a user's hand or other object at a desired range/location and dispense measured/selected amounts of the sheet material. The proximity sensor can be manually or automatically adjustable. In addition, or in the alternative, one or more pairs of IR sensors (e.g., an emitter and a corresponding detector) that are arranged about/within the discharge chute 22 and transmit/receive signals across the discharge path P to sense or detect the presence or absence of sheet material or other object within the discharge chute or otherwise along the feed path.

In embodiments, any suitable sensor, however, such as a photoelectric, light curtain, or other similar sensing systems/detectors, can be used to detect the presence of a user's hands or other object placed along the dispenser housing 16, and/or the feeding of a selected amount of the sheet material 12 can be used, without departing from the present disclosure. In addition, various sensor arrays and/or control systems can be used, such as disclosed in U.S. patent application Ser. Nos. 15/185,937, and Ser. No. 14/256,019, the complete disclosures of which are incorporated by reference as if set forth fully herein.

As indicated in FIGS. 1A and 1C, the dispenser housing 16 includes a roll support mechanism 30, for holding at least one of a roll 32 of the sheet material supply 20 of the sheet material 12. The roll support mechanism 30 can include a pair of supports or arms 34 coupled to the dispenser housing 16 and supporting the roll of sheet material 12, such as indicated at 36. These support arms 34 may be fixedly arranged to hold the sheet material supply 20 of sheet material in a spaced relationship with respect to the feed roller 18. For example, the support arms 34 can be attached or coupled to the dispenser housing 16 by sliding or snap-fitting at least a portion of the supports/arms within grooves or slots 37 defined along a rear portion 36 of the dispenser housing 16. However, in other embodiments, the support arms 34 further can be connected to the dispenser housing 16 in any suitable manner, such as with one or more fasteners or other suitable connection mechanisms. As a further alternative, the support arms also can be integrally formed with the housing without departing from the present disclosure. In additional or alternative constructions, the support arms 34 also may be biased or urged, such as by a spring or other suitable biasing mechanism(s), or by a general resiliency, toward the feed roller 18 to urge or direct the sheet material supply 20 of sheet material downwardly toward or against the feed roller 18.

In addition, the feed roller 18 will be movably or rotatably mounted within the dispenser, for example, being rotatably coupled to one or more walls or other portions of the dispenser housing 16. For example, the ends of the feed roller 18 can be connected, mounted, or otherwise coupled to the dispenser housing 16 by one or more bearing assemblies and/or other suitable support mechanisms that support and allow for rotation of the feed roller 18 in relation to the dispenser housing 16.

As illustrated in FIG. 1B, the dispenser 10 further generally can include one or more pressing roller(s) 60. The pressing roller(s) 60 can be biased toward engagement with the feed roller 18, so as to engage and urge or press the sheet material against the feed roller 18 with a force sufficient to draw or pull the sheet material therebetween upon rotation of the feed roller 18. The pressing roller(s) 60 can be mounted within the dispenser housing 16, such as with the ends thereof held within one or more arms or supports of a bracket 60A in a manner to enable rotation of the pressing roller(s) 60. The bracket 60A also can be biased by a biasing member, such as a spring, so that the pressing roller(s) 60 can be urged toward the driven feed roller 18.

Additionally, or in the alternative, one or more of the pressing roller(s) 60 further can be disposed within a frame or other structure and biased toward the feed roller 18 such as by compressing/tension springs or other suitable springs, biased cylinders, or other biasing mechanisms. In one construction, the frame can support at least two pressing rollers and also can be pivotable to enable one pressing roller to move away from the feed roller as needed, while the other roller is pivoted into closer contact with the feed roller (not shown). In addition, or alternatively, in some embodiments, the pressing roller(s) 60 may be driven by drive mechanism, for example, off of the motor that drives the feed roller or by a separate drive, so as to help facilitate feeding of the sheet material 12.

The feed roller drive assembly 14 includes at least one driving mechanism, e.g., a motor 74, that is in communication with the feed roller 18 so as to drive movement/rotation thereof (FIG. 1C). The motor 74 can include a brushless servo or stepper motor or other, similar type of variable speed electric motor, and communicates with the control system 506 of the dispenser 10 to receive instructions and power for activating and driving the feed roller 18 through a dispensing cycle (e.g., a determined time, number of revolutions, etc.), so as to feed the selected or desired amount/length of the sheet material through the discharge chute 22 of the dispenser 10.

In one additional aspect, the drive system/assembly 14 also can include a transmission assembly 76 for transferring power between the motor 74 and the feed roller 18. For example, the transmission assembly 76 can include a drive belt 78 and/or drive gears coupling the motor 74 to the feed roller 18. In alternative constructions, the feed roller drive assembly 14 can include a gear assembly including a plurality of intermeshing gears that operatively connect the motor 74 and the feed roller 18. Any suitable transmission mechanisms, device, assemblies, etc. can be used for transferring power between the driving mechanism and the feed roller, without departing from the scope of the present disclosure.

In addition, FIGS. 2A-2G illustrate an embodiment of a dispenser 10, which can be configured for dispensing sheet materials from multiple supplies 20 of a sheet material 12. The dispenser 10 of the FIGS. 2A-2G can have a substantially similar construction to the dispenser of FIGS. 1A-1C, including a housing 16 within which multiple (e.g., two) supplies 20 of sheet material 12 are received. For example, an embodiment, the dispenser 10 of FIGS. 2A-2G can be used feed tissue, toilet paper, or other, similar sheet materials, with each roll of sheet material being supported by a roll support mechanism 30. As indicated in FIG. 2C, an embodiment, the roll support mechanism can include a pair of supports or arms 34 can be pivotally attached to a portion of the housing 16, for example, being pivotally attached to a cover portion 16A of the housing. As indicated in FIG. 2C, the rolls of sheet material can be received on the support arms 34 when the support arms are in a raised or pivoted up configuration, and then can be lowered into a feeding configuration with a portion and of the sheet material of each roll of sheet material being engaged with the dispensing mechanism 15 as shown in FIG. in 2B.

In embodiments, the dispensing mechanism 15 of the dispenser of FIGS. 2A-2G can include a pair of feed rollers 18, sets of pressing rollers 60 and a feed roller drive assembly 14 that can be coupled to each of the feed rollers 18 or selectively driving each of the feed rollers as needed for feeding for selectively feeding the sheet material from one or the other of the supply rolls. For example, in embodiments, the feed roller drive assembly 14 can include at least one driving mechanism such as a motor 74 can be linked in communication with each of the feed rollers 18. The driving mechanism can be in communication with the control system 506 of the dispenser to receive control instructions and power for activating and driving a selected one of the rollers 18 during a dispensing operation or cycle (e.g., a selected time, number of revolutions, etc.), so as to feed the selected or desired amount/length of the sheet material through the discharge chute 22 of the dispenser 10.

According to some aspects, the feed roller drive assembly 14 can have a similar construction as shown FIG. 1C, including, in embodiments, a transmission assembly 76 for transferring power between the motor 74 and the feed rollers 18. For example, the transmission assembly 76 can include a drive belt 78 and a drive gear assembly that can include a series of drive gears coupling the motor 74 to the feed roller 18. In addition, a gear clutch or one-way bearing assembly 80 can be provided, for example, being positioned between the drive gears linked to each of the feed rollers and with the drive belt being extended thereabout. In embodiments, the drive motor can be a reversible motor and can be selectively driven by the control system in a first direction to feed the sheet material form a first one of the supply rolls, and in a second direction to feed the sheet material form the second supply roll (e.g., when the first supply roll has been exhausted or depleted). When the driving direction of the motor is switched, the gear clutch or one-way bearing assembly can cause the drive belt to be disengaged from the drive gear associated with one of the supply rolls (e.g., the first supply roll) and engaged with the drive gear of the other supply roll (e.g., the second supply roll) to selectively switch feeding between the supply rolls as needed. Any suitable transmission mechanisms, device, assemblies, etc. can be used for transferring power between the driving mechanism and the feed roller, without departing from the scope of the present disclosure.

Still further, is some other embodiments, a pair of drive motors could be provided, each linked to an associated one of the feel rollers. In embodiments, the drive motors can be selectively operable by the control system for selectively feeding sheet material from one or the other of the supplies of sheet material.

In addition, in embodiments of the dispensers such as shown in FIGS. 1A-2G, one or more paper detection sensors 608 can be positioned along/adjacent the discharge of the dispenser, for example, being located within a throat portion of the discharge, while in other embodiments, the paper detection sensor(s) can be positioned above the throat or below the outlet of the discharge. In embodiments, the paper detection sensor(s) 608 can comprise a signal device such as a proximity sensor switch or the like adapted to detect the presence or absence of paper within the discharge or throat and send a signal to notify the controller of the control system of the dispenser that the sheet material has or has not been removed once the dispensing operation has ended. By way of example, the paper detection sensor(s) can include an infrared emitter and detector that can be adapted to detect the presence or absence of the sheet material, though any suitable sensor can be employed such as a proximity sensor or other detector, a magnetic switch, or a mechanical switch. After receiving a signal indicating removal of the sheet material, the control system 506 further can reset the dispensing mechanism for a next dispensing operation of cycle.

In addition, in embodiments, the dispenser also could include a pawl member or additional paper sensor configured to indicate the removal of the sheet material from the dispenser. In such embodiments, the pawl member can be positioned to be engaged by the sheet material as a user pulls/removes the paper from the dispenser, and when released, can indicate the sheet material has been removed, and if not released or returned to a home position when the dispensing operation is completed, a signal can be sent to the controller to indicate the sheet material has not been removed.

Still further, in some constructions, the dispenser can include a cutting mechanism configured to move or be actuated at a prescribed or preset point during a revolution of the feed roller 18, or after a prescribed rotation of the feed roller 18 so as to selectively cut or perforate the sheet material after a desired or prescribed length or portion of the sheet material has been fed or dispensed. In embodiments, the dispenser may include one or more suitable moveable cutting members or can include a stationary blade or tear bar or other cutting member disposed adjacent or along the dispenser housing 16 so that a user can separate a sheet or measured amount of the material by grasping and pulling the sheet across the stationary tear bar.

FIGS. 3A-3C illustrate an additional example embodiment of a dispenser 300 that can be part of the dispensing system, which dispenser comprises a liquid or fluid dispenser such as soaps, sanitizers, shampoos and/or conditioners, lotions, and other fluids. In addition, it will be understood that the terms “fluid” and “liquid” can refer to any type of fluid media and are not to be construed as limited to particular fluids or liquids.

In embodiments, the fluid dispenser 300 generally includes a dispenser housing 302 that supports/houses a supply or reservoir 304 that contains/stores a liquid, e.g., liquid soap, hand sanitizer, etc. For example, in embodiments, such as shown in FIGS. 3B-3C, the dispenser 10 generally will include at least one supply 304 of a fluid or liquid “F”, which can comprise a bottle, bag, or other, similar container defining a supply chamber configured to hold a selected volume of the fluid material. For example, in embodiments, the fluid supply can contain a selected or predetermined volume of fluid that can provide a preferred or selected number of fluid dispenses (e.g., the supply can include a container with approximately 1000 ml to 2000 ml, or other volumes as needed). Still further, in some embodiments, the supply 304 can be configured to be refillable, while in other embodiments, the supply can be provided as a single use container that can be recycled once empty to help protect against contamination of the fluid therein.

As further illustrated in FIG. 3C, in embodiments, the dispenser 300 further will include a dispensing assembly 320 including a dispensing mechanism 321 in communication with the fluid supply 304 and configured to selectively draw and dispense prescribed amounts or “shots” of the fluid from the fluid supply, and a control system 325. In embodiments, the control system 325 can comprise a controller 326 that can include one or more processors, and, in embodiments, can be contained within a housing or cassette 322 within which the dispensing mechanism 321 is housed, or, in other embodiments, can be separate from the dispensing assembly and dispensing mechanism.

In embodiments, the dispenser 300 can include an internal power supply 330, such as a series of batteries 331, while in other embodiments, the dispenser could be coupled to an external power source, such as a building power supply, external batteries, or other sources. In embodiments, the controller will include programming or otherwise will be configured to initiate and control operation of the dispensing mechanism to perform a dispensing operation to dispense the fluid.

In embodiments, the dispensing mechanism 321 can include at least one pump 323 that will be driven by a motor or other actuator to draw an amount of fluid from the fluid supply 304 and direct the fluid to a discharge for the dispenser. In addition, in embodiments, the fluid dispenser 300 further can include one or more nozzles 335 located at a discharge outlet 336 for providing the fluid to the user. In some embodiments, the nozzles can be configured to cause the fluid to be dispensed as a foam, while in other embodiments, the fluid can be dispensed in a substantially liquid or gel form.

The fluid dispenser 300 further can include one or more activation sensors 310 or an array of activation sensors, e.g., including an IR sensor, proximity sensor or other detector configured to detect the presence of an individual within a selected activation zone, proximity or range adjacent the dispenser. The one or more activation sensors generally will be in communication with the control system 325 of the dispenser, so as to communicate/transmit an activation signal to the controller 326 upon detection of a user within the selected activation zone, proximity of range, in response to which the controller can control operation of the pumping mechanism 308 to initiate and conduct a dispensing operation.

In embodiments, the one or more activation sensors 310 can be configured as proximity sensors to gather information that is related to the presence of an object, such as a user's hand, near or proximate the fluid dispenser 300. Accordingly, in operation, when a user places their hand in proximity to the one or more sensors 310, the one or more sensors 310 provide a signal to the controller to activate the pumping mechanism 308 for dispensing a select or prescribed amount of liquid. Still further, in embodiments, the control system, including the controller and at least one activation sensor, and the dispensing mechanism and other operative components of the dispenser can be in communication with a power management system that further is coupled to the power source, e.g., one or more batteries or an AC power source, and will be operable to control the supply of power to the controller 326, at least one activation sensor 310, dispensing mechanism 308, and other operative components to minimize power usage by the dispenser, as discussed further below.

FIGS. 4A-6D illustrate example embodiments of dispensers with embodiments of activation sensor assemblies 401 of the activation system 400 of the dispensers that can be located in various locations along portions of the dispensers and which can provide varying activation zones, proximities or ranges for the capture of a user (e.g., capture of infrared radiation form the hand or other part of a user) to generate an activation signal to initiate a dispensing operation. FIG. 4A shows an example embodiment of a dispenser 10, which is shown as similar to the embodiment of a dispenser shown in FIGS. 2A-2G, generally including a dispenser housing that can support/house one or more supplies of a material to be dispensed, e.g., paper towel, hand towel, fluid containers, etc. The dispenser further can include a discharge outlet through which the sheet material can be dispensed from the dispenser housing to the user, and a dispensing mechanism (FIGS. 4C-4D), for directing or moving the material to be dispensed from the supply to the discharge outlet.

In embodiments, as shown in FIGS. 2A, 4A, 5A, and 6A-6F, the dispenser 10 can include a recess or pocket 100 in which an activation system 400 can be located. As indicated in FIGS. 4A-6F, the pocket or recess of the dispenser can have various configurations. For example, in FIGS. 2A and 4A-4D, the pocket or recess can have a generally elongated substantially rectangular construction, while in FIGS. 5A-5B, the pocket or recess can have a smaller area. FIG. 6A shows another embodiment in which the pocket or recess is formed without a bottom or lower edge, and which also may be configured with open sides.

In embodiments, the activation system 400 may include at least one activation sensor 414 e.g., including an IR sensor, proximity sensor or other, similar sensor in communication with a controller 510 of a control system 506 of the dispenser/dispensing system and with a power management system 510. As shown in FIG. 7C, the power management system will be configured to selectively control the flow/transmission and use of power by the operative components of the dispenser, including the controller, the dispensing mechanism, the one or more activation sensors of the activation system 400, and other potential operative components (e.g., one or more transmitters, status indicators, lights, dispenser controls such as resets, etc.). In embodiments, the power management system can be configured to separately and independently connect or disconnect the operative components and the power supply. For example, in embodiments, the power management system can be configured to connect only the one or more sensors of the activation system upon detection of infrared radiation withing the prescribed detection area, zone, or range while maintaining the other components in a powered-off or decoupled state; while in other embodiments, the power management system can be configured to periodically power on or off the operative components, for example, disconnecting one or more of the components from the power supply after a prescribed time or other event; and/or connecting the control system or a Wi-Fi transmitter of the dispenser to the power supply at intervals to send updated dispenser information including dispenser usage information such as amounts dispensed, times of dispensing, personnel using the dispenser, error conditions such as jams, no supply or low supply or low power.

In embodiments, the activation system 400 can be located within the pocket or recess 100 formed or defined along a portion (e.g., a front or lower forward edge) of the housing 16 of the dispenser, such that at least one activation sensor 414 (e.g., a hand sensor) thereof can be located within a generally protected area. The at least one activation sensor can be arranged/oriented within the pocket or recess for sensing the presence of a user or a portion thereof within a selected activation zone, proximity or range, for example, when the user places their hand within the pocket or recess 100. The location of the at least one activation sensor within the pocket or recess can help define or focus the activation zone, proximity or range and help avoid inadvertent detections that could initiate an unwanted dispensing operation. In response to detection of a user by the at least one activation sensor 414, the controller 506 may determine which of the plurality of supplies 404 for the dispensing mechanism 408 to activate and start a dispensing cycle or operation for dispensing sheet material from the selected supply of sheet material.

In embodiments, the activation sensor 414 of the activation system 400 can be configured as a proximity sensor with a focused/selected activation zone, proximity, range or area 405 for detection of the presence of an object, such as a user's hand, near or proximate the dispenser 400, such as, for example, detecting the user's hand when it is placed in the pocket or recess 100, but not when it is simply near the dispenser, to help reduce activations or the dispenser being fully powered up and in a “powered on,” ready to dispense state such as shown in FIGS. 8D-8E and 9C-9E. FIG. 2B, and 4A-6F illustrate various example embodiments or arrangements of activation sensors, activation sensor arrays, and different configurations of activation zones for the activation systems 400 according to principles of the present disclosure.

For example, one non-limiting example embodiment sensor that could be used as an activation sensor 414 of the activation system 400 is generally shown in FIG. 4B and can include an infrared emitter 402A and an infrared receiver or detector 402A, which can be configured to emit an IR beam (indicated by 403). Other types or configurations of sensors also can be used.

In other embodiments such as illustrated in FIGS. 4A, 4B-4C, 5A-5B, 6A, and 6C-6F, the activation system 400 can include a variety of types and arrangements of activation sensors 414. For example, FIGS. 4A and 4C-4D show arrangement of activation sensors including one or more emitters 402A and one or more receivers 402B that can be located along an upper portion or surface 101 and a lower portion or surface 102 of the pocket or recess 100. The emitters and receivers can be arranged in an opposing relationship, with one or more IR beams being transmitted therebetween. The transmission of the IR beams can be varied so as to provide different activation zone configurations as indicated at 405.

In addition, in other embodiments such as shown in FIGS. 5A-5B, a pair of activation sensors can be positioned along opposite sides 104A/104B of the pocket or recess 100 and can project generally conically shaped sensing beams that can cross to define an activation zone with overlapping fields of coverage.

FIGS. 6A-6F show still further arrangements of activation sensors 414 and sensor arrays 401, which can define/create still other activation zone configurations and can extend in varying directions, including forwardly, towards the sides of the dispenser, downwardly below the bottom of the dispenser (e.g., where the pocket or recess does not include a bottom portion), or combinations thereof. As also shown in FIGS. 6E-6F, in embodiments, an activation sensor array, which can include one or more activation sensors 414 positioned along a rear portion 107 of the pocket or recess, adjacent the PIR sensor of the power management system of the dispenser, and which can project a sensing beam forwardly out to the open front portion 108 and, in embodiments, at least partially downwardly and/or to the sides.

Accordingly, in operation, in embodiments, when a user places their hand in proximity to the one or more activation sensors 414, the activation system 400 provides a signal to the controller of the dispenser to activate the dispensing mechanism for dispensing the sheet material. The controller further is coupled to a power source, e.g., one or more batteries or an AC power source (e.g., the dispenser could include a plug-in type of connector for connecting to a building power supply), such as the power source 508 in FIG. 7A to power the controller, the dispensing mechanism 408, and the activation system 400.

In an embodiment, after receiving a signal indicating removal of the sheet material, the controller further can activate a paper detection sensor 416 to verify that the sheet material has been removed from the discharge chute.

FIG. 7A-7D shows an exemplary embodiment of the dispensing system 500 for at least one dispenser as previously described. The elements of FIG. 7A-7D are herein described in relation to elements of the previous figures. In FIG. 7A, the dispensing system 500 can include at least one dispenser including a dispensing assembly 501, which, in embodiments, can comprise a dispensing mechanism 502, at least one activation sensor 414, and a control system 506 including a controller 514 (which can, in embodiments, include one or more processors). The dispensing system 500 further generally will include a power source or supply 508, and a power management system 510 in communication with or coupled to the dispensing assembly 501 and the power source 508 and having at least one passive infrared radiation (PIR) sensor 512.

In embodiments, the power source or supply 508 can comprise an internal power supply (e.g., one or more batteries or power cells such as shown in FIG. 3D), or can comprise an external power source (e.g., the dispensing system and/or one or more individual dispensers thereof can be coupled to a building power source, battery pack, etc.). In embodiments, the power management system 510 associated with the dispensing system (e.g., with each dispenser or multiple dispensers of the dispensing system also can include or can be in communication with one or more switches 518, which can be integrated with the power management system, or, in some embodiments, can be a separate component(s) positioned between the operative components of an associated dispenser (e.g., the controller of the control system, one or more activation sensors, the dispensing mechanism, indicators, dispenser controls, etc.) and the PIR sensor 512.

FIG. 7B, in an embodiment, shows the dispensing system 500. The dispensing system 500 may include the dispensing assembly 501 in communication with the activation sensor 414. The activation sensor may be in further communication with the switch 518. In embodiments, the switch may be in further communication with the PIR sensor 512 and the power management system 510. The PIR sensor 512 and the power management system 510 may be in further communication with the power source 508.

FIG. 7C, in an embodiment, shows the dispensing system 500 with two switches 518, a first switch 518A and a second switch 518B. The dispensing system 500 may include the dispensing assembly 501 in communication with the second switch 518B. The second switch 518B may be in further communication with the power source 508 and the activation sensor 414. The activation sensor 414 may be in further communication with the first switch 518A. The first switch 518A may be in further communication with the PIR sensor 512 and the power management system 510. The PIR sensor 512 and the power management system 510 may be in further communication with the power source 508.

FIG. 7D shows an example embodiment of a dispensing system 500 according to principles of the present disclosure. The dispensing system 500 generally can include a dominant or lead dispenser 520 and a plurality of follower or drone dispensers 522 in communication with the lead dispenser 520. The plurality of drone dispensers 522 can include one or more liquid dispensers 522A, such as soap dispensers, hand sanitizer dispensers, etc. and/or one or more sheet material dispensers 522B, such as tissue dispensers, paper towel dispensers, etc. In embodiments, the dispensers 520/522 can include the dispensers 10, 300, or 400. The lead dispenser 520 can include a sheet material dispenser (e.g., tissue dispensers, paper towel dispensers, etc.) or a liquid dispenser (e.g., a soap dispenser or a hand sanitizer dispenser). Each of the dispensers 520/522 can generally include the power management system 510, the activation sensor 414, and the dispensing assembly 501 as shown in FIG. 7A-7C.

The lead dispenser 520 further can be in communication with a network 524, such as cloud based network or other suitable public (e.g., the Internet) or private network, and the lead dispenser 520 can provide one or more signals, packets, etc. including, or otherwise related to, dispenser information and/or alerts, notifications, etc., generated by the lead dispenser 520 and the drone dispensers 522 to the network 524 for access by a system operator, maintained personnel, etc. The dispenser information can include information related to power levels (e.g., battery levels), supply levels (e.g., information related to remaining amounts of sheet material or liquid), usage (e.g., times and dates of when the dispenser was used, amounts the dispenser was activated during a specific time period, other usage rates or statistics, etc.) The alerts, notifications, etc. can be generated, e.g., if the dispensers 520/522 are experiencing a low power, low supply, error states, etc.

The lead dispenser 520 and drone dispensers 522 may include a short-range receiver/transmitter 526A/526B, such as a Bluetooth® or other suitable RF or short-range signal receiver/transmitter, to facilitate communication between the lead dispenser 520 and the drone dispensers 522 (see, e.g., FIG. 7D). The lead dispenser 520 also can include an additional, long-range receiver/transmitter 528, such as a narrowband (“NB”) receiver/transmitter (e.g., 4G, LTE, 5G, etc.) or other suitable transmitter/receiver, e.g., Wi-Fi, for transmitting and/or receiving information to/from or otherwise communicating with the network 524.

Further, in some variations, the drone dispensers 522 can have a substantially similar construction to the lead dispenser 520 and will include a long-range receiver/transmitter 528, such as a narrowband (“NB”) receiver/transmitter (e.g., 4G, LTE, 5G, etc.) or other suitable transmitter/receiver, e.g., Wi-Fi, etc. In these variations, the long-range transmitter/receivers 528 of one or more of the drone dispensers 522 can be deactivated or generally maintained in a low power state.

As further indicated in FIG. 7D, the lead dispenser 520 and drone dispensers 520 each can include the at least one PIR sensor 512A/512B configured to detect infrared radiation of a person or people (e.g., that is indicative of the presence or movement of individuals within a prescribed detection range, area, zone, etc. covered by each of the PIR sensors 512A/512B around their respective dispensers 520/522). The PIR sensors 512A/512B can be in communication with the control system 506 and the power management system 510 of their respective dispensers 520/522. The control system 506 and dispensing assembly 501 of the respective dispensers 520/522 can be deactivated and activated based upon/responsive to signals received from their corresponding PIR sensors 512A/512B and their corresponding activation sensor 414 of the power management system 510.

When the PIR sensors 512A/512B detects infrared radiation from a person or persons (e.g., indicating an occupied state or mode—such as a person entering a bathroom or an individual stall), at least one respective activation sensor 414 for that dispenser can be connected to or otherwise placed in communication with a corresponding power source 508 so as to receive power/current therefrom. In another embodiment, when one of the respective PIR sensors 512A/512B detects infrared radiation from a person or persons, everyone or more of the dispensers 520/522 may be directed (e.g., receive a signal) to connect their corresponding activation sensor 414 to the power source 508 while the other dispenser components (e.g., the controller/control system 506, the dispensing assembly 501, and dispensing mechanism 502, various other sensors, etc.) remain disconnected from the power source 508.

For example, in embodiments, power management systems of each of the dispensers can include a transmitter and receiver that can send a signal to other power management systems to power-on or wake up (e.g., connect to the power supply) at least one activation sensor associated therewith. In other embodiments, the lead dispenser could be configured such that its power management system can connect its control system to power to enable the control system to send a signal to the other dispensers (e.g., drone dispensers) to place their activation sensors in a powered on or active state.

Thereafter, when the activation sensor 414 of a respective dispenser 520/522 detects infrared radiation from a person or persons, their respective control system 506, dispensing assembly 501, and other dispenser components in communication therewith can be connected to or otherwise placed in communication with their corresponding power source 508 so as to receive power/current therefrom. The other non-activated dispensers 520/522 may remain in a low power state.

When the PIR sensors 512A/512B do not detect infrared radiation from a person or people, indicating an unoccupied state or mode (e.g., no one is detected within the room or within an individual stall), their respective control system 506 and other dispenser components in communication therewith can be placed in a low or minimal power state and disconnected from the power source 508 such that no power/current is provided to the control system 506 and the dispensing assembly 501 such that the dispensing assembly 501, the activation sensor 414, and other dispenser components in communication therewith are deactivated and do not draw or consume power from the power source 508. That is, in the low or minimized power state, only the PIR sensors 512A/512B will draw or consume power from the power source 508.

In some aspects, the control systems 506 (and other dispenser components in communication therewith) can finish or complete any on-going work, functions, operations, etc. thereof and generate and transmit one or more command signals to place the short-range transmitter/receivers 526A/526B (as well as the long-range transmitter/receiver 528) into a low power/power off state. As the control system 506 enters into its power down sequence, the control system 506 can generate and output one or more signals, e.g., a low level signal, to the switch 518 such that the switch 518 is in an open or “off” state, disconnecting the power source 508 from their associated dispenser controllers 506 to completely shut down/power off the dispenser controllers 506 and substantially all other components of the dispensers 520/522 including the activation sensors 414, except for the PIR sensors 512A/512B, and, in some variations, the short-range 526/526B and long-range 528 transmitter/receivers. In these variations, the transmitters/receivers 526/526B and 528 can be placed in a low power or sleep state. In this regard, the control system 506 and substantially all other components of the dispensers 520/522 (e.g., activation sensors 414, dispensing mechanisms 502, etc.) are generally decoupled from the power sources 508 such that the control systems 506 and other operative components of the dispensers 520/522 do not consume or draw power from the power sources 508 while in such low/minimal power state.

FIGS. 8A-8E show additional elements of the dispensing system 500 of FIG. 7A-7D in various states of operation. In embodiments, the dispensing system 500 in FIGS. 8A-8E may further include the dispensing mechanism 502, which may include at least one motor. In some embodiments, more than one motor circuit 602 can also be provided, including, for example, a motor one circuit 602A and a motor two circuit 602B. Two motor circuits 602A/602B may be used when the dispenser 400 includes a plurality of supplies 404 as shown in FIG. 4B.

In addition, as shown in FIGS. 8A-8E, in embodiments, the power management system 510 may be in communication with the power source 508, and a voltage regulator or limiter 604 can also be provided along the pathway between the power management system 510 and the power source. The voltage limiter also can be provided at other locations, such as between the motor circuits or other components of the dispensing assembly 501.

In some embodiments, the dispensing system 500 may further include a push button system 606, which may include a push button left 606A and a push button right 606B, the paper detection system 608 for detecting the supply level of the fluid or sheet material, which may include a paper detection left sensor 608A and a paper detection right sensor 608B depending on the type of dispenser 10/300/400/520/522 implemented, a Wi-Fi dedicated CPU 610, and a night light circuit 612. The PIR sensor 512 and the switch 518 may be included in the power management system 510 in FIGS. 8A-8E.

The dispensing system 500 is configured to selectively activate and deactivate certain elements of the dispenser based on the detected presence of a user within a prescribed area or zone around the dispenser using the PIR sensor 512 and the activation sensor 414. The elements will be further described in connection with dispensers such as previously described.

In embodiments, the power management system 510 can include a switch 518, e.g., a triode, or other suitable switching mechanism, which is coupled to a lead or other coupling/connector connecting the power source 508, and the PIR sensor 512. The control system 506, the activation sensor 414, and dispensing mechanism, and transmitter can be linked to the power management system, or the power management system can be incorporated into the control system. The switch 518 can be activated by the power management system 510 to connect and disconnect the control system 506 from the power source 508 (e.g., in FIG. 7A, the switch 518 includes a first, disconnected position wherein the control system 506 and the activation sensor 414 are disconnected from the power source 508 and the PIR sensor 512 is connected to the power source, the switch 518 includes a second, connected position wherein the activation sensor 414 is connected to the power source 508 and the control system 506 is disconnected from the power source 508, and the switch 518 includes a third, connected position wherein the control system 506 and the power source 508 are connected).

In this regard, when closed by the power management system, the switch 518 can connect or couple the controller of the control system 506 to the power source 508 such that the controller can draw or consume power from the power source 508, and when opened by the switch 518 can disconnect or decouple the controller from the power source 508 such that the control system 506 does not draw or consume power from the power source 508.

In embodiments, the switch 518 can further couple the activation sensor 414 to the power source 508 such that the activation sensor 414 can draw or consume power from the power source 508 independently of the control system and other operative components (e.g., while the controller, etc . . . remain disconnected from the power supply). The switch 518 also can disconnect or decouple the activation sensor 414 from the power source 508 such that at least one activation sensor 414 does not draw or consume power from the power source 508 upon a signal from the controller or other condition (e.g., expiration of a prescribed time period of no activity).

In FIG. 7C, in embodiments, there may be two switches 518, 518A and 518B. The power management system 510 may couple the activation sensor 414 to the power source 508 via the first switch 518A upon a signal from the PIR sensor 512 to the first switch 518A. Thereafter, the activation sensor 414 may couple the dispensing assembly 501 to the power source 508 via the second switch 518B one it detects a user withing a selected activation zone, by sending a signal from the activation sensor 414 to close the second switch 518B and connect the control system to the power supply.

In embodiments, the power management system 510 may operate the PIR sensor 512 to determine if the activation sensor 414 shall connect/couple or disconnect/decouple from the power source 508 via the switch 518. The power management system 510 may operate the activation sensor 414 to determine if the control system 506 shall connect/couple or disconnect/decouple from the power source 508.

Once a dispensing operation is initiated, the dispensing mechanism 502 can dispense a selected amount of fluid or sheet material when activated by the control system 506. For example, in embodiments, the dispensing mechanism 502 may include a motor 74 shown in FIG. 1B and feed roller 18 and in response to the activation signal, the controller can connect the motor to the power supply and operate the motor to drive the feed roller to feed a length of sheet material. Alternatively, in other embodiments, the dispensing mechanism, such as shown in FIG. 3, can be configured for dispensing fluids such as soap or sanitizer.

In addition, in still other embodiments, the dispenser can include dispensing mechanism 502 as shown in FIGS. 8A-8E that may include two motor circuits, a motor one circuit 602A and a motor two circuit 602B, for selectively feeding from a plurality of supplies of material. However, the dispensing mechanism 502 may only require one motor circuit depending on the type of dispenser used. The dispensing mechanism may be in communication with the power source 508 or receive power from the control system 506, e.g., the dispensing mechanism 502 may receive power from the power source 508 through the control system 506 or directly from the power source 508 as shown in FIG. 8A.

The activation sensor 414 is configured to be activated by a user to initiate dispensing of the selected amount of the fluid or sheet material. In embodiments, the activation sensor 414 may include a proximity sensor, or an infrared sensor configured to capture infrared radiation of a user within a defined activation range, area, or zone. For example, as shown in FIGS. 2 and 4A-4B, the dispenser 10 can include an activation area or zone 405 that can, in embodiments, be located above or within a recess or pocket 406 in the dispenser into which the user will place their hand for activation of a dispensing operation. In embodiments, the activation sensor 414 may be configured such that it may not detect the presence of the user to initiate a dispensing cycle or operation until the user has placed their hand inside the pocket or recess 100 In other embodiments, the activation zone can be directed along the front or a lower portion of the dispenser housing and can be focused to minimize inadvertent activations. In embodiments, the activation sensor 414 also may include a dedicated CPU for processing signals from the control system 506 and the power management system 510.

The at least one activation sensor may be powered by the power management system 510 through the switch 518 or the control system 506, depending on different embodiments of the disclosure. When the activation sensor 414 is activated and detects a user, the activation sensor 414 may send a signal to the control system 506 to activate the dispensing mechanism 502. The activation sensor 414 may operate the switch 518 to connect the control system 506 to the power source 508. In another embodiment, the activation sensor 414 may send a signal to the power management system 510 to activate the switch 518 to connect the controller of the control system 506 to the power source 508.

In embodiments where the activation zone is focused inside a pocket or recess or otherwise, the user may be generally required to take some action, such as putting their hand in the pocket or recess, to activate the activation sensor. Otherwise, the activation sensor can remain in a standby mode and will not cause the controller/main CPU of the control system to be reconnected to the power supply and signal the controller to start a dispensing cycle or operation. This can help conserve power/reduce current draw by the dispenser, by maintaining the control system, dispensing mechanism and other operative components of the dispenser in a powered off condition disconnected from then power supply, which in turn, can help conserve and extend the life of batteries or a rechargeable power supply for the dispenser.

In embodiments, the control system 506 may be in communication with the activation sensor 414, the power source 508, the power management system 510, the PIR sensor 512, the switch 518, the push button system 606, the paper detection system 608, the Wi-Fi dedicated CPU 610, and the night light circuit 612. The control system 506 may control when the attached elements are activated and receive power. The control system 506 may connect to the power source 508 by the power management system 510 when the activation sensor 414 captures infrared radiation of one or more individuals within the prescribed detection range, area, or zone.

The power source 508 of the dispensing system 500 may be one or more batteries, an alternating current (AC) distribution system, or other AC or direct current (DC) power sources. The power source 508 may be in communication with the power management system 510, the control system 506, and the power management system 510.

In embodiments, the power management system 510 includes the PIR sensor 512 and the switch 518. In some embodiments, the switch 518 or other connector could be a separate element in communication with the power management system 510. The PIR sensor 512. An embodiment of PIR sensor 512 is shown in FIG. 9. The PIR sensor 512 may have a larger prescribed detection range, area, or zone than the activation sensor 414. The power management system 510 may be in communication with the control system 506, the activation sensor 414, and the switch 518. In addition, in some embodiments, the activation sensor 414 could comprise a similar infrared sensor.

In embodiments, the power management system 510 may be in communication with the paper detection system 608, the Wi-Fi dedicated CPU 610, and the night light circuit 612. The power management system 510 may operate the switch 518 to connect and disconnect the control system 506, the activation sensor 414, and other elements to the power source 508.

In embodiments, the power management system 510 may determine which elements need power based on sensor inputs from the PIR sensor 512 and the activation sensor 414. The power management system 510 further includes a processor, such as a microprocessor, CPU, etc., memory, and computer programming stored in the memory and executed by the processor for control of the switch 518 and the PIR sensor 512. In embodiments, the PIR sensor can include a processor and a memory (or can be in communication with a memory) and programming sense or detect infrared radiation and operate the switch. The power management system 510 (e.g., the CPU of the PIR sensor) also may include a timer to determine a time period lapsed during the power saving states as described below in relation to FIGS. 8B-8E.

The Wi-Fi dedicated CPU 610 can include a long-range receiver/transmitter such as a narrowband (“NB”) receiver/transmitter (e.g., 4G, LTE, 5G, etc.) or other suitable transmitter/receiver, e.g., Wi-Fi, for transmitting and/or receiving information to/from or otherwise communicating with a network. Further, in some variations, the long-range transmitter/receivers of the dispensing system 500 can be deactivated or generally maintained in a low power state. The Wi-Fi dedicated CPU 610 may transmit sensor information and the status of the fluid or sheet material supply as determined by the paper detection system 608. The Wi-Fi dedicated CPU 610 may include the short-range receiver/transmitter 526A/526B as shown, e.g., in FIG. 7D, such as a Bluetooth® or other suitable RF or short-range signal receiver/transmitter, to facilitate communication. The paper detection system 608 may include the paper detection sensor 416 in FIG. 4B to verify that the sheet material has been removed from the discharge chute.

The night light circuit 612 can illuminate at least a portion of the front recess of the dispenser assembly with visible light (e.g., proximate to and/or adjacent the dispenser activation sensor assembly 401). Accordingly, the night light circuit 612 can guide a user with respect to where the user should gesture in order to activate a dispensing operation. The night light circuit 612 can be configured to illuminate in one or more colors of light in order to provide information about the state and/or status of aspects of the dispenser assembly (e.g., supply levels, battery life, etc.). In addition, in embodiments, the night light circuit 612 can be turned on when the PIR sensor 512 detects a user and can be configured to use a minimal power draw, while one or more components of the dispensing assembly 501 can be placed in a low-power or non-active but ready state. For example, the activation sensor 414 can be connected to the power source 508 but maintained in a low power or sleep state until the user is detected by the activation sensor 414, and the other components such as the control system 506 and dispensing mechanism 502 can be maintained in a powered-off state.

Example embodiments of the power saving states of the dispensing system 500 will now be described in reference to FIG. 7A-7D and FIGS. 8B-8E.

During an unoccupied state, as shown in FIG. 7B, the PIR sensor 512 (an example of which is generally illustrated in FIG. 10), of the power management system 510 (FIG. 7B) will be in a powered on state, coupled to the power source 508 while the switch 518 is placed in an open state to disconnect from the power source 508 all other elements of the dispensing system 500, including the dispensing assembly 501, the controller/control system 506, at least one activation sensor 414, the dispensing mechanism 502 and Wi-Fi transmitter and CPU. In an embodiment, in the unoccupied state, the current draw from the power source 508 may be limited to the power necessary to activate the power management system 510 and the PIR sensor 512.

For example, in embodiments, the power management system can substantially lower the current draw by the dispensing system, such as by disconnecting or shutting the control system, dispensing mechanism and activation sensor(s) from the power supply such that those components are effectively powered down or off, and only the PIR sensor may be drawing power from the power supply. In embodiments, the current draw can be lowered to as low as about 40 μA or lower, and in some embodiments, in a range from about 10 μA to about 80 μA, about 10 μA to about 70 μA, about 10 μA to about 60 μA, about 10 μA to about 50 μA, about 10 μA to about 40 μA, about 10 μA to about 30 μA, about 10 μA to about 20 μA, about 20 μA to about 80 μA, about 20 μA to about 70 μA, about 20 μA to about 60 μA, about 20 μA to about 50 μA, about 20 μA to about 40 μA, about 20 μA to about 30 μA, about 30 μA to about 80 μA, about 30 μA to about 70 μA, about 30 μA to about 60 μA, about 30 μA to about 50 μA, about 30 μA to about 40 μA, about 40 μA to about 80 μA, about 40 μA to about 70 μA, about 40 μA to about 60 μA, about 40 μA to about 50 μA, about 50 μA to about 80 μA, about 50 μA to about 70 μA, about 50 μA to about 60 μA, about 60 μA to about 80 μA, about 60 μA to about 70 μA, and finally, about 70 μA to about 80 μA.

The control system 506, the dispensing assembly 501, dispensing mechanism, and at least the at least one activation sensor 414 will remain disconnected from the power source 508 when the dispensing system 600 is in the unoccupied or non-triggered state. The dispensing system 500 may remain in an unoccupied state until the PIR sensor 512 captures infrared radiation of one or more individuals within the prescribed detection range, area, or zone.

The dispensing system 500 may be in an occupied state as shown in FIG. 8C when an individual's presence is detected by the PIR sensor 512. The occupied state may be activated when the PIR sensor 512 captures infrared radiation of one or more individuals within the prescribed detection range, area, or zone. In the occupied state, the power management system 510 may connect or couple via the switch 518 the activation sensor 414 to the power source 508. The power management system 510 may disconnect or decouple from the power source 508 the control system 506, the dispensing mechanism 502, and the paper detection system 608, and other components of the dispensing assembly 501 while the activation sensor 414 is connected to the power source 508. Therefore, the only elements drawing current are the activation sensor 414 and the power management system 510 including the PIR sensor 512. In an embodiment, in the occupied state, the dispensing system may draw an electric current of about 260 μA.

In an embodiment, the power management system 510 may connect or couple, via the switch 518A, the activation sensor 414 to the power source 508. The other operative components such as the control system, dispensing assembly, other sensors, etc. can stay disconnected from power.

In an alternative embodiment, when the dispensing system 500 is in an occupied state, the power management system 510 may connect or couple the dispensing assembly 501 to the power source 508 so as to be ready to dispense, while the controller of the control system 506 may remain in a low power or sleep mode. The sleep mode of the control system 506 draws less power than when the control system 506 is activating the dispensing mechanism 502 and is in a ready to dispense state. The control system 506 may draw enough power from the power source 508 to activate the activation sensor 414 and the night light circuit 612.

In another embodiment, when the dispensing system 500 is in an occupied or fully powered-on and operational state, the power management system 510 may connect the night light circuit 612 to illuminate the activation zone of the activation sensor 414.

In an embodiment, the dispensing system 500 may remain in the occupied state for a predetermined period of time and then return to the unoccupied state.

The dispensing system 500 may be in a ready to dispense state as shown in FIG. 8D. The ready to dispense state may be activated when the dispensing system is in the occupied state and the activation sensor 414 detects a user within the prescribed detection range, area, or zone of the activation sensor 414. When a user is detected by the activation sensor 414, the power management system 510 may connect or couple the dispensing assembly 501 including the control system 506 to the power source 508. The power management system 510 and the control system 506 may further connect to the power source 508 the paper detection system 608, the dispensing mechanism 502, the night light circuit 612, the push button system 606, and the paper detection system 608. In the ready to dispense state, the control system 506 may signal the dispensing mechanism 502 to dispense the fluid or sheet material when the activation sensor 414 detects a user within the prescribed detection range, area, or zone.

In an embodiment, the activation sensor 414 may connect or couple the dispensing assembly 501 to the power source 508 via the second switch 518B.

In an embodiment, the dispensing system 500 may remain in a ready to dispense state for a period of time for the dispensing mechanism 502 to dispense the fluid or sheet material and then the dispensing system 500 may return to the occupied state. In another embodiment, the dispensing system 500 may remain in the ready to dispense state for a predetermined period of time before returning to the occupied state.

The dispensing system 500 may be in a ready to dispense and ready to send state, ready to send a data packet including dispenser status information as shown in FIG. 8E when the control system 506 receives a signal from the push button system 606 while in the ready to dispense state. When in the ready to dispense and ready to send state, the control system 506 and the power management system 510 may activate the Wi-Fi dedicated CPU 610. The Wi-Fi dedicated CPU 610 may transmit dispenser status information or data from the paper detection system 608 to notify an administrator of the usage and/or status of the dispenser. For example, the dispenser status information can include dispenser usage information (e.g., activity such as a number of dispensing operations, times of peak use, who used the dispenser, fault conditions, a supply status of the liquid or sheet material within the dispensing system 500, and/or other data. The dispensing system 500 may remain in the ready to dispense and ready to send data packet state for a predetermined period of time before returning to the occupied state or the ready to dispense state.

In addition, in embodiments, the dispenser(s) of the dispensing system, and/or individual components such as the power management system, control system, activation system, and other components, can incorporate a smart architecture. For example, in embodiments, a dedicated CPU or processor of the PIR sensor 512 of the power management system, the main CPU or controller of the dispenser control system 506, the CPU 610 for the Wi-Fi connection and/or transmission system, the CPU for the activation/hand sensor 414 and CPUs for the one or more paper detection sensors, and a dedicated CPU or processor for the dispensing mechanism (e.g., in embodiments, each motor of the dispensing mechanism can include a dedicated CPU, or in some embodiments, the motors could be linked as part of a package or series responsive to a common CPU), can be configured as replaceable, “plug-and-play” components that can be replaced or changed as needed without substantively affecting the operation of the dispenser. This can enable the dispenser to be scalable or adapted to meet different uses and/or changing usage conditions.

In addition, with each of the operative components having its own CPU or processor/controller, each component can be selectively operated, independently of the others, which can further promote load shedding to help reduce power consumption by the dispenser. For example, as indicated in FIGS. 8A-9E, in embodiments, when the dispenser is initially set-up for operation, the PIR sensor may be the only component in operation and receiving power (e.g., FIG. 86B).

In embodiments, when the PIR detects infrared radiation, it can cause one or more other components to be activate, for example, connecting the activation sensor to the power supply and sending a signal to the CPU of the activation sensor to cause the activation sensor 414 to activate/be readied for detection of a user (e.g., detecting a user's hand being placed near the activation/hand sensor 414). The activation sensor can be controlled by its CPU to actively or passively scan for a user, and in embodiments, can be maintained in its activated state for a selected time period, after which, if not activated, it can be powered down, or can be put in a sleep mode at a lower power if the PIR sensor detects infrared radiation within its predefined zone or area, while the main CPU of the control system, the CPU's of the dispensing mechanism, paper detection sensors, Wi-Fi connection/transmitter, and night light circuit can remain disconnected from the power supply. Thereafter, when the activation sensor detects the presence of a user, its CPU can cause the main CPU to be connected to the power supply and can send an activation signal to the main CPU to start a dispensing cycle, at which point, the main CPU can connect the dispensing mechanism to the power supply and cause the motor(s) thereof to feed a length of sheet material or supply a selected amount of a fluid.

The other components (e.g., the paper detection sensor(s), Wi-Fi connection/transmitter, and night light circuit) each can selectively remain disconnected from the power supply or can be powered on with the reconnection or powering up of the activation sensor, the main CPU, and/or the dispensing mechanism. Alternatively, one or more of the components such as the paper detection sensor(s), Wi-Fi connection/transmitter, night light circuit, or other components can be individually connected to power and placed in an operable state, while other components such as the activation/hand sensor can remain powered-off (e.g., disconnected from the power supply). In some embodiments, some such other components (e.g., the control system) can be connected to power but can be put into a low power or sleep mode, or, in some embodiments, disconnected from power to further help minimize power consumption by the dispenser.

In various embodiments, the control system 506 of each dispenser of the dispensing system 500 also can be configured to send an alert or transmit notifications and/or data to a building control or server, or to an administrator to notify them of a fault condition such as low power, low sheet material or fluid supplies, malfunctions, usage data, etc. The control system 506 further can be programmed to send such an alert or transfer usage data, etc. once the control system 506 has been reconnected to power, as a generally automated function. By way of example, in embodiments such as indicated in FIG. 7E, once the control system 506 is connected to power, the CPU controlling the Wi-Fi connection can likewise be connected to power, either in conjunction with the control system, or upon command of the control system establishing the power connection, and once a network connection (e.g., to building personnel/management, a central server, building/facility management server, the cloud, etc.) has been established, an alert or notification can be sent automatically. After the alert or notification has been sent, the Wi-Fi CPU can be powered down or disconnected from the power supply, even if the dispenser is still in an occupied/dispensing state. In embodiments, the Wi-Fi CPU can remain in its powered on state until a confirmation of receipt of the alert or notification by a recipient (e.g., building personnel/management, a central server, building/facility management server, the cloud, etc.), and once confirmation is received, can then be powered down or off.

In other embodiments, such alerts, notifications, data transfers or other communications can be sent at selected time intervals (e.g., the power management system 510 can include programming to wake up the control system 506 after an elongated period of inactivity to communicate with a central server, such as an administrator control, etc.). Alternatively, the CPU of the Wi-Fi transmitter or communication assembly can be connected to power while the control system, etc. remain disconnected. The Wi-Fi CPU can be connected at specified times, or when the PIR detects infrared radiation and can send a data pocket transmission and then can be powered off or down. For example, as indicated in FIG. 9E, the Wi-Fi CPU can be placed in a sleep or low power mode while the dispenser is in a ready to dispense mode, and activated when an alert of notification is to be sent, and then can be put back in a low power or sleep mode.

Alternatively, or in addition to communications sent on a selected time basis, such alerts, notifications, data transfers or other communications can be sent when a problem is detected. For example, if a low supply, paper jam, low power, or other fault condition is detected when the control system is connected to power by the power management system, the Wi-Fi CPU can be transitioned to a powered on state and can send the alert or notification to the dispenser, such as indicated in FIG. 9E.

Still further, in some embodiments, the dispensing system 500, and individual dispensers thereof, can be configured to download data, alerts, etc. regarding the performance of the dispenser(s)/dispensing system 500 to a storage medium such as a hosted, cloud-based storage. For example, the control system 506 of each dispenser, or a lead dispenser 520 of a system of multiple dispensers (FIG. 7D), can be programmed to automatically download date regarding the dispenser(s) performance, fault conditions, etc., such as when powered on, or at a time interval such as specified time or times of the day. Users, such as homeowners, businesses, etc. can be provided with a storage subscription where such data can be stored and accessed as needed.

FIGS. 9A-9E show an embodiment of the dispensing system 700, which incorporates similar features and components as shown with respect to the dispensing system 500. FIGS. 9A-9E show the dispensing system in unpowered, unoccupied, occupied, ready to dispense, and Wi-Fi powered on states as determined by the power management system 510 and the control system 506.

FIGS. 9A-9E further show additional details of the power management system 510. For example, switch 518 is shown. The dispensing system 700 may also include a boost IC 702 (boost converter integrated circuit) for increasing a lower input voltage to a higher output voltage. Additionally, a second voltage regulator or limiter 604B may be used to provide a stable output voltage to the control system 506.

In embodiments, the activation sensor 414 (e.g., a hand sensor), in addition to its dedicated CPU, can include a hand receiving infrared motion sensor (IRM) 704, which is used to monitor movement near the dispenser when the dispenser is in the occupied state. For example, in embodiments where the dispenser can include a pocket or recess in which at least one activation sensor is positioned, the activation sensor can generate an activation zone that can be focused e.g., can be configured to have a selected detection range, within the confines of the pocket, or in a selected area along a portion of the dispenser such that a user will be required to take some affirmative action, such as placing their hand within the pocket or recess to be detected by the activation sensor.

In embodiments, the IRM can be configured to operate in similar fashion to the PIR sensor of the power management system. For example, the activation sensor can be maintained in a powered off state disconnected from the power supply, and when the PIR sensor or the power management system detects infrared radiation within the prescribed area, space or zone, it can initially activate a switch to connect the IRM to power, while, in embodiments, the CPU of the activation sensor remains in a low power mode (an in some embodiments, possibly remaining disconnected from the power supply) until the IRM detects the presence of the user and wakes the activation sensor CPU.

Alternatively, in some embodiments, the IRM sensor can remain connected to the power supply and can separately wake-up or cause the operative components of the dispenser to be connected to the power supply. For example, in embodiments, the PIR sensor can, upon detection of infrared radiation, connect the control system to the power supply, but the control system can be maintained in a low power or sleep mode. When the IRM sensor detects the user's hand and wakes up the activation sensor and causes an activation signal to be sent to the control system, the control system can be placed in a fully powered on (occupied) and awake/ready to dispense state (FIGS. 9C-9E).

As indicated in FIGS. 9C-9E, in embodiments, when the dispenser is in its powered on (occupied) state, some of the operative components such as the motors and paper detection sensors can remain in a powered off or low power state and can be turned on when the dispenser is ready to dispense, as indicated in FIG. 9D. However, in embodiments, some features of the dispenser, such as the Wi-Fi connection can remain in a powered off condition. As noted, the Wi-Fi CPU can be maintained disconnected from the power supply, or it can be placed in a sleep or low power mode until the dispenser is placed in the ready to dispense state.

According to the present disclosure, the term “about” can be understood to cover values in the range of ±0.5 μA, though about can reflect any suitable value range, such as ±0.1 μA, ±1 μA, or up to ±3 μA, or other value ranges as will be understood by those skilled in the art. In this regard, the dispensing system according to embodiments of the present disclosure helps to save significant power in comparison to typical steady state dispensing systems. In still other still other embodiments, if, for example, an alert indicating a fault condition such as a low supply condition, has been generated, the dispenser can further be configured to connect to the network and transmit an update to indicate if/when the fault condition has been cleared.

In addition, in various embodiments, the control system 506 (FIGS. 7A-9E) of the dispenser can include or can be in communication with a communication system including one or more transmitters and/or receivers (e.g., Wi-Fi transmitter module 610) configured to at least periodically monitor the selected activation area or zone within a determined proximity of the dispenser to detect signals being transmitted by transmitters carried by individuals. For example, each dispenser can be part of a dispensing system 560 located within a hospital or other, similar facility in which compliance with certain health and safety protocols (e.g., requirements for doctors, nurses and other personnel to perform handwashing and other sanitizing operations upon entering and/or leaving a patient's room). In some such instances, the dispensing system can communicate with or be integrated with or as a part of a compliance system for the facility.

In some embodiments, the compliance system can include a facility control system and a plurality of badges or other identifying devices that can be assigned to or otherwise associated with a particular individual. Each badge can include at least one transmitter that can be configured to transmit identifying signals that can include codes or other identification information for the individual carrying or associated with the badge. The badge transmitters can be configured to periodically send out signals that can be received by the control system of the dispenser (e.g., by one or more receivers of the control system) to announce to the dispenser that a particular individual has moved into sufficient proximity to the dispenser to require the individual to perform mandated health and safety protocols.

In embodiments, the control system of each dispenser of the dispensing system can look for or request identification signals from an individual's badge and multiple points/times within a dispensing operation. For example, when the control system of the dispenser initially receives a first signal from the individual's badge, it can identify the presence of that particular individual and proximity to the dispenser. The dispenser control system can then search for one or more additional identification signals (e.g., at least a second signal) in conjunction with the activation of the dispensing mechanism, and search for an additional identification signal from the individual's badge (e.g., a third signal) upon completion of the dispensing operation.

In embodiments, if, for example, one or more of the additional (e.g. second and/or third) identification signals are not received and/or a dispensing operation is not initiated after the first identification signal from the individual's badge is detected (e.g., within a prescribed time or if some other event occurs), the control system can generate a noncompliance record indicating that the individual failed to use the dispenser. In embodiments, such a noncompliance record can be transmitted together with the identification of the individual associated with a detected badge to server, network, mobile application, facility control, or other system, for tracking and monitoring of movements of individuals throughout the facility and their compliance with health and safety protocols. In embodiments, the non-compliance record can be included as part of the dispenser usage information transmitted at selected times (e.g., upon powering on the control system, when the PIR sensor detects infrared radiation of one or more individuals, or at a selected time interval).

By recording the information regarding which individuals have been in proximity to a dispenser, and if they were detected as present during the entirety of a dispensing operation, records can be generated to ensure compliance with safety protocols, and also to monitor and track movements of individuals to determine if they were in areas where the should not be, or where a potentially dangerous or other condition or event occurred. The records also can be compared to a database of the facility control system to help in tracking and other purposes.

FIG. 10 illustrates an example of a PIR sensor 512, which can include a lens 513 that can be configured to create a selected detection zone, area, range or distance as shown at 511. For example, a generally comical IR transmission, having an angle “α” can be generated, extending for a predetermined distance and/or width. Other configurations also can be provided.

Any of the features of the various embodiments of the disclosure can be combined with, replaced by or otherwise configured with other features of other embodiments of the disclosure without departing from the scope of this disclosure.
