DETAILED DESCRIPTION

The detailed description of exemplary embodiments herein makes reference to the accompanying drawings, which show exemplary embodiments by way of illustration. While these embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosures, it should be understood that other embodiments may be realized and that logical changes and adaptations in design and construction may be made in accordance with this disclosure and the teachings herein. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation.

The scope of the disclosure is defined by the appended claims and their legal equivalents rather than by merely the examples described. For example, the steps recited in any of the method or process descriptions may be executed in any order and are not necessarily limited to the order presented. Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component or step may include a singular embodiment or step. Also, any reference to attached, fixed, coupled, connected, or the like may include permanent, removable, temporary, partial, full, and/or any other possible attachment option. Surface shading lines may be used throughout the figures to denote different parts but not necessarily to denote the same or different materials.

Systems, methods, and apparatuses may be used to interfere with voluntary locomotion (e.g., walking, running, moving, etc.) of a target. For example, a conducted electrical weapon (e.g., “CEW”) may be used to deliver a current (e.g., stimulus signal, pulses of current, pulses of charge, etc.) through tissue of a human or animal target. Although typically referred to as a conducted electrical weapon, as described herein a “CEW” may refer to a conducted electrical weapon, a conducted energy weapon, an electronic control device, and/or any other similar device or apparatus configured to provide a stimulus signal through one or more deployed projectiles (e.g., electrodes). Moreover, principles of the present disclosure may be applied to other less-lethal and non-lethal weapons and devices, including, for example, electronic devices configured to deploy projectiles towards a target, electronic devices configured for training purposes (e.g., to imitate less-lethal and/or non-lethal weapons), electronic devices configured for virtual reality (e.g., to imitate real-world use of less-lethal and/or non-lethal weapons), and/or the like.

A stimulus signal carries a charge into target tissue. The stimulus signal may interfere with voluntary locomotion of the target. The stimulus signal may cause pain. The pain may also function to encourage the target to stop moving. The stimulus signal may cause skeletal muscles of the target to become stiff (e.g., lock up, freeze, etc.). The stiffening of the muscles in response to a stimulus signal may be referred to as neuromuscular incapacitation (“NMI”). NMI disrupts voluntary control of the muscles of the target. The inability of the target to control its muscles interferes with locomotion by the target.

A stimulus signal may be delivered through the target via terminals coupled to the CEW. Delivery via terminals may be referred to as a local delivery (e.g., a local stun). During local delivery, the terminals are brought close to the target by positioning the CEW proximate to the target. The stimulus signal is delivered through the target's tissue via the terminals. To provide local delivery, the user of the CEW is generally within arm's reach of the target and brings the terminals of the CEW into contact with or proximate to the target.

A stimulus signal may be delivered through the target via one or more (typically at least two) wire-tethered electrodes. Delivery via wire-tethered electrodes may be referred to as a remote delivery (e.g., a remote stun). During a remote delivery, the CEW may be separated from the target up to the length (e.g., 15 feet, 20 feet, 30 feet, etc.) of the wire tether. The CEW launches the electrodes towards the target. As the electrodes travel toward the target, their respective wire tethers deploy behind the electrodes. The wire tether electrically couples the CEW to the electrode. The electrode may electrically couple to the target thereby coupling the CEW to the target. In response to the electrodes connecting with, impacting on, or being positioned proximate to the target's tissue, the current may be provided through the target via the electrodes (e.g., a circuit is formed through the first tether and first electrode, the target's tissue, and the second tether and second electrode).

Terminals or electrodes that contact or are proximate to the target's tissue deliver the stimulus signal through the target. Contact of a terminal or electrode with the target's tissue establishes an electrical coupling (e.g., circuit) with the target's tissue. Electrodes may include a spear that may pierce the target's tissue to contact the target. A terminal or electrode that is proximate to the target's tissue may use ionization to establish an electrical coupling with the target's tissue. Ionization may also be referred to as arcing.

In use (e.g., during deployment), a terminal or electrode may be separated from the target's tissue by the target's clothing or a gap of air. In various embodiments, a signal generator of the CEW may provide the stimulus signal (e.g., current, pulses of current, etc.) at a high voltage (e.g., in the range of 40,000 to 100,000 volts) to ionize the air in the clothing or the air in the gap that separates the terminal or electrode from the target's tissue. Ionizing the air establishes a low impedance ionization path from the terminal or electrode to the target's tissue that may be used to deliver the stimulus signal into the target's tissue via the ionization path. The ionization path persists (e.g., remains in existence, lasts, etc.) as long as the current of a pulse of the stimulus signal is provided via the ionization path. When the current ceases or is reduced below a threshold (e.g., amperage, voltage), the ionization path collapses (e.g., ceases to exist) and the terminal or electrode is no longer electrically coupled to the target's tissue. Lacking the ionization path, the impedance between the terminal or electrode and target tissue is high. A high voltage in the range of about 50,000 volts can ionize air in a gap of up to about one inch.

A CEW may provide a stimulus signal as a series of current pulses. Each current pulse may include a high voltage portion (e.g., 40,000-100,000 volts) and a low voltage portion (e.g., 500-6,000 volts). The high voltage portion of a pulse of a stimulus signal may ionize air in a gap between an electrode or terminal and a target to electrically couple the electrode or terminal to the target. In response to the electrode or terminal being electrically coupled to the target, the low voltage portion of the pulse delivers an amount of charge into the target's tissue via the ionization path. In response to the electrode or terminal being electrically coupled to the target by contact (e.g., touching, spear embedded into tissue, etc.), the high portion of the pulse and the low portion of the pulse both deliver charge to the target's tissue. Generally, the low voltage portion of the pulse delivers a majority of the charge of the pulse into the target's tissue. In various embodiments, the high voltage portion of a pulse of the stimulus signal may be referred to as the spark or ionization portion. The low voltage portion of a pulse may be referred to as the muscle portion.

In various embodiments, a signal generator of the CEW may provide the stimulus signal (e.g., current, pulses of current, etc.) at only a low voltage (e.g., less than 2,000 volts). The low voltage stimulus signal may not ionize the air in the clothing or the air in the gap that separates the terminal or electrode from the target's tissue. A CEW having a signal generator providing stimulus signals at only a low voltage (e.g., a low voltage signal generator) may require deployed electrodes to be electrically coupled to the target by contact (e.g., touching, spear embedded into tissue, etc.).

In various embodiments, a CEW may include at least two terminals at the face of the CEW. A CEW may include two terminals for each bay that accepts a deployment unit (e.g., cartridge). The terminals are spaced apart from each other. In response to the electrodes of the deployment unit in the bay having not been deployed, the high voltage impressed across the terminals will result in ionization of the air between the terminals. The arc between the terminals may be visible to the naked eye. In response to a launched electrode not electrically coupling to a target, the current that would have been provided via the electrodes may arc across the face of the CEW via the terminals.

The likelihood that the stimulus signal will cause NMI increases when the electrodes that deliver the stimulus signal are spaced apart at least 6 inches (15.24 centimeters) so that the current from the stimulus signal flows through the 6 or more inches of the target's tissue. In various embodiments, the electrodes preferably should be spaced apart at least 12 inches (30.48 centimeters) on the target. Because the terminals on a CEW are typically less than 6 inches apart, a stimulus signal delivered through the target's tissue via terminals likely will not cause NMI, only pain.

A series of pulses may include two or more pulses separated in time. Each pulse delivers an amount of charge into the target's tissue. In response to the electrodes being appropriately spaced (as discussed above), the likelihood of inducing NMI increases as each pulse delivers an amount of charge in the range of 55 microcoulombs to 71 microcoulombs per pulse. The likelihood of inducing NMI increases when the rate of pulse delivery (e.g., rate, pulse rate, repetition rate, etc.) is between 11 pulses per second (“pps”) and 50 pps. Pulses delivered at a higher rate may provide less charge per pulse to induce NMI. Pulses that deliver more charge per pulse may be delivered at a lesser rate to induce NMI. In various embodiments, a CEW may be hand-held and use batteries to provide the pulses of the stimulus signal. In response to the amount of charge per pulse being high and the pulse rate being high, the CEW may use more energy than is needed to induce NMI. Using more energy than is needed depletes batteries more quickly.

Empirical testing has shown that the power of the battery may be conserved with a high likelihood of causing NMI in response to the pulse rate being less than 44 pps and the charge per pulse being about 63 microcoulombs. Empirical testing has shown that a pulse rate of 22 pps and 63 microcoulombs per pulse via a pair of electrodes will induce NMI when the electrode spacing is about 12 inches (30.48 centimeters).

In various embodiments, a CEW may include a handle and one or more deployment units. The handle may include one or more bays for receiving the deployment units. Each deployment unit may be removably positioned in (e.g., inserted into, coupled to, etc.) a bay. Each deployment unit may releasably electrically, electronically, and/or mechanically couple to a bay. In various embodiments, a CEW may include a bay configured to receive a magazine comprising one or more electrodes. A deployment (e.g., launch) of the CEW may launch one or more electrodes toward a target to remotely deliver the stimulus signal through the target.

In various embodiments, a deployment unit may include two or more electrodes that are launched at the same time. In various embodiments, a deployment unit may include two or more electrodes that may be launched at separate times. Launching the electrodes may be referred to as activating (e.g., firing) a deployment unit. After use (e.g., activation, firing), a deployment unit may be removed from the bay and replaced with an unused (e.g., not fired, not activated) deployment unit to permit launch of additional electrodes.

In various embodiments, and with reference to FIGS. 1A and 1B, a CEW 1 is disclosed. CEW 1 may be similar to, or have similar aspects and/or components with, any other CEW disclosed herein including the CEWs previously discussed herein. It should be understood by one skilled in the art that FIG. 1B is a schematic representation of CEW 1, and one or more of the components of CEW 1 may be located in any suitable position within, or external to, housing 10. CEW I may comprise a housing 10 and one or more deployment units 20.

Housing 10 (e.g., handle, CEW handle, etc.) may be configured to house various components of CEW 1 configured to enable deployment of the deployment units 20, provide an electrical current to the deployment units 20, and otherwise aid in the operation of CEW 1, as discussed further herein. Although depicted as a firearm in FIGS. 1A and 1B, housing 10 may comprise any suitable shape and/or size. Housing 10 may comprise a handle end 12 opposite a deployment end 14. Deployment end 14 may be configured, and sized and shaped, to receive one or more deployment units 20. Handle end 12 may be sized and shaped to be held in a hand of a user. For example, handle end 12 may be shaped as a handle to enable hand-operation of the CEW by the user. In various embodiments, handle end 12 may also comprise contours shaped to fit the hand of a user, for example, an ergonomic grip. Handle end 12 may include a surface coating, such as, for example, a non-slip surface, a grip pad, a rubber texture, and/or the like. As a further example, handle end 12 may be wrapped in leather, a colored print, and/or any other suitable material, as desired.

In various embodiments, housing 10 may comprise various mechanical, electronic, and electrical components configured to aid in performing the functions of CEW 1. For example, housing 10 may comprise one or more triggers 40, control interfaces 45, processing circuits 50, power supplies 60, and/or signal generators 70. Housing 10 may include a guard 30. Guard 30 may define an opening formed in housing 10. Guard 30 may be located on a center region of housing 10 (e.g., as depicted in FIGS. 1A and 1B), and/or in any other suitable location on housing 10. Trigger 40 may be disposed within guard 30. Guard 30 may be configured to protect trigger 40 from unintentional physical contact (e.g., an unintentional activation of trigger 40). Guard 30 may surround trigger 40 within housing 10.

In various embodiments, trigger 40 be coupled to an outer surface of housing 10, and may be configured to move, slide, rotate, otherwise become physically depressed upon application of the physical contact. For example, trigger 40 may be actuated by physical contact applied to trigger 40 from within guard 30. Trigger 40 may comprise a mechanical or electromechanical switch, button, trigger, or the like. For example, trigger 40 may comprise a switch, a pushbutton, and/or any other suitable type of trigger. Trigger 40 may be mechanically and/or electronically coupled to processing circuit 50. In response to trigger 40 being activated (e.g., depressed, pushed, etc. by the user), processing circuit 50 may enable deployment of one or more deployment units 20 from CEW 1, as discussed further herein.

In various embodiments, power supply 60 may be configured to provide power to various components of CEW 1. For example, power supply 60 may provide energy for operating the electronic and/or electrical components (e.g., parts, subsystems, circuits) of CEW 1 and/or one or more deployment units 20. Power supply 60 may provide electrical power. Providing electrical power may include providing a current at a voltage. Power supply 60 may be electrically coupled to processing circuit 50 and/or signal generator 70.

The memory may comprise a tangible, non-transitory computer-readable memory. Instructions stored on the tangible non-transitory memory may allow processing circuit 50 to perform various operations, functions, and/or steps, as described herein.

The term “non-transitory” is to be understood to remove only propagating transitory signals per se from the claim scope and does not relinquish rights to all standard computer-readable media that are not only propagating transitory signals per se. Stated another way, the meaning of the terms “non-transitory computer-readable memory” and “non-transitory computer-readable storage medium” should be construed to exclude only those types of transitory computer-readable media which were found in In re Nuijten to fall outside the scope of patentable subject matter under 35 U.S.C. § 101.

In response to detecting the control event, processing circuit 50 may be configured to perform various operations and/or functions, as discussed further herein. Processing circuit 50 may also include a sensor (e.g., a control sensor) attached to control interface 45 and configured to detect a control event of control interface 45. The sensor may comprise any suitable mechanical and/or electronic sensor capable of detecting a control event in control interface 45 and reporting the control event to processing circuit 50.

In various embodiments, processing circuit 50 may be electrically and/or electronically coupled to power supply 60. Processing circuit 50 may receive power from power supply 60. The power received from power supply 60 may be used by processing circuit 50 to receive signals, process signals, and transmit signals to various other components in CEW 1. Processing circuit 50 may use power from power supply 60 to detect an activation event of trigger 40, a control event of control interface 45, or the like, and generate one or more control signals in response to the detected events. The control signal may be based on the control event and the activation event. The control signal may be an electrical signal.

In various embodiments, processing circuit 50 may be electrically and/or electronically coupled to signal generator 70. Processing circuit 50 may be configured to transmit or provide control signals to signal generator 70 in response to detecting an activation event of trigger 40. Multiple control signals may be provided from processing circuit 50 to signal generator 70 in series. In response to receiving the control signal, signal generator 70 may be configured to perform various functions and/or operations, as discussed further herein.

In various embodiments, signal generator 70 may be configured to receive one or more control signals from processing circuit 50. Signal generator 70 may provide an ignition signal to deployment unit 100 based on the control signals. Signal generator 70 may be electrically and/or electronically coupled to processing circuit 50 and/or deployment unit 100. Signal generator 70 may be electrically coupled to power supply 60. Signal generator 70 may use power received from power supply 60 to generate an ignition signal. For example, signal generator 70 may receive an electrical signal from power supply 60 that has first current and voltage values. Signal generator 70 may transform the electrical signal into an ignition signal having second current and voltage values. The transformed second current and/or the transformed second voltage values may be different from the first current and/or voltage values. The transformed second current and/or the transformed second voltage values may be the same as the first current and/or voltage values. Signal generator 70 may temporarily store power from power supply 60 and rely on the stored power entirely or in part to provide the ignition signal. Signal generator 70 may also rely on received power from power supply 60 entirely or in part to provide the ignition signal, without needing to temporarily store power.

In various embodiments, signal generator 70 may include circuits for receiving electrical energy and for providing the stimulus signal. Electrical/electronic circuits (e.g., components) of signal generator 70 may include capacitors, resistors, inductors, spark gaps, transformers, silicon controlled rectifiers (“SCRs”), analog-to-digital converters, and/or the like.

Signal generator 70 may be controlled entirely or in part by processing circuit 50. In various embodiments, signal generator 70 and processing circuit 50 may be separate components (e.g., physically distinct and/or logically discrete). Signal generator 70 and processing circuit 50 may be a single component. For example, a control circuit within housing 10 may at least include signal generator 70 and processing circuit 50. The control circuit may also include other components and/or arrangements, including those that further integrate corresponding function of these elements into a single component or circuit, as well as those that further separate certain functions into separate components or circuits.

Signal generator 70 may be controlled by the control signals to generate an ignition signal having a predetermined current value or values. For example, signal generator 70 may include a current source. The control signal may be received by signal generator 70 to activate the current source at a current value of the current source. An additional control signal may be received to decrease a current of the current source. For example, signal generator 70 may include a pulse width modification circuit coupled between a current source and an output of the control circuit. A second control signal may be received by signal generator 70 to activate the pulse width modification circuit, thereby decreasing a non-zero period of a signal generated by the current source and an overall current of an ignition signal subsequently output by the control circuit. The pulse width modification circuit may be separate from a circuit of the current source or, alternatively, integrated within a circuit of the current source. Various other forms of signal generators 70 may alternatively or additionally be employed, including those that apply a voltage over one or more different resistances to generate signals with different currents. In various embodiments, signal generator 70 may include a high-voltage module configured to deliver an electrical current having a high voltage. In various embodiments, signal generator 70 may include a low-voltage module configured to deliver an electrical current having a lower voltage, such as, for example, 2,000 volts.

Responsive to receipt of a signal indicating activation of trigger 40 (e.g., an activation event), a control circuit provides an ignition signal to deployment unit 100. For example, signal generator 70 may provide an electrical signal as an ignition signal to deployment unit 100 in response to receiving a control signal from processing circuit 50. In various embodiments, the ignition signal may be separate and distinct from a stimulus signal. For example, a stimulus signal in CEW 1 may be provided to a different circuit within deployment unit 100, relative to a circuit to which an ignition signal is provided. Signal generator 70 may be configured to generate a stimulus signal. In various embodiments, a second, separate signal generator, component, or circuit (not shown) within housing 10 may be configured to generate the stimulus signal. Signal generator 70 may also provide a ground signal path for deployment unit 100, thereby completing a circuit for an electrical signal provided to deployment unit 100 by signal generator 70. The ground signal path may also be provided to deployment unit 100 by other elements in housing 10, including power supply 60.

In various embodiments, power supply 60 may comprise an electrical circuit (e.g., a power supply electrical circuit, a power supply circuit, etc.) defining an electrical coupling between processing circuit 50 and power supply 60. For example, the electrical circuit may comprise an electrical path (e.g., a conductive path), one or more switches controlling the electrical circuit, and/or any other suitable or desired electrical circuit components. The electrical circuit may be configured to provide energy (e.g., electricity) from power supply 60 to processing circuit 50. In some embodiments, the electrical circuit may also be configured to provide energy from power supply 60 to one or more other components of CEW 1, such as control interface 45 and/or signal generator 70. Processing circuit 50 may be in electrical communication with one or more components of the electrical circuit. Processing circuit 50 may be configured to detect an electrical property of the electrical circuit. Processing circuit 50 may be configured to sample a voltage (e.g., a power supply voltage, a power supply circuit voltage, a power supply switch voltage, etc.) of the electrical circuit.

In various embodiments, trigger 40 may comprise an electrical circuit (e.g., a trigger electrical circuit, a trigger circuit, etc.) defining an electrical coupling between processing circuit 50 and trigger 40. For example, the electrical circuit may comprise an electrical path (e.g., a conductive path), one or more switches controlling the electrical circuit, and/or any other suitable or desired electrical circuit components. The electrical circuit may be configured to allow trigger 40 to provide trigger signals to processing circuit 50. The electrical circuit may be configured to allow processing circuit 50 to detect trigger signals from trigger 40. Processing circuit 50 may be in electrical communication with one or more components of the electrical circuit. Processing circuit 50 may be configured to detect an electrical property of the electrical circuit. Processing circuit 50 may be configured to sample a voltage (e.g., a trigger voltage, a trigger circuit voltage, a trigger switch voltage, etc.) of the electrical circuit.

In various embodiments, signal generator 70 may comprise one or more electrical circuits (e.g., signal generator electrical circuits, signal generator circuits, etc.) defining electrical couplings between signal generator 70 and one or more components of CEW 1.

For example, signal generator 70 may comprise a first electrical circuit (e.g., a first signal generator circuit, a signal generator input circuit, a charging circuit, etc.) defining an electrical coupling between power supply 60 and signal generator 70. The first electrical circuit may comprise an electrical path (e.g., a conductive path), one or more switches controlling the first electrical circuit, and/or any other suitable or desired electrical circuit components. The first electrical circuit may be configured to provide energy (e.g., electricity) from power supply 60 to signal generator 70. In some embodiments, the first electrical circuit may comprise one or more capacitors configured to store (e.g., accumulate) the energy received from power supply 50. In some embodiments, the first electrical circuit may comprise one or more switches and/or other suitable or desired electrical circuit components configured to control the provision of energy from power supply 60 to the one or more capacitors. In some embodiments, the first electrical circuit may comprise a high-voltage module (HV module) (e.g., a high-voltage transformer, an HV transformer, etc.) configured to receive energy from power supply 60. The HV module may receive pulses of energy from power supply 60. The pulses of energy may charge the HV module. Processing circuit 50 may be in electrical communication with one or more components of the first electrical circuit. Processing circuit 50 may be configured to detect an electrical property of the first electrical circuit. Processing circuit 50 may be configured to sample an input (e.g., an electrical input) of the first electrical circuit. In some embodiments, processing circuit 50 may be configured to determine (e.g., count) whether pulses of energy from power supply 60 successfully charged the HV module. For example, during a startup of CEW 1, during a load test of a CEW, and/or at any other suitable time, the HV module may receive a number of pulses from power supply 60 to charge the HV module and/or to ensure the HV module is capable of delivering a current. Processing circuit 50 may determine the number of pulses of energy that successfully charge the HV module and/or the number of pulses of energy that did not successfully charge the HV module.

As a further example, signal generator 70 may comprise a second electrical circuit (e.g., a second signal generator circuit, a signal generator output circuit, a discharging circuit, etc.) defining an electrical coupling between signal generator 70 and one or more electrical contacts proximate a bay 20 of housing 10. The second electrical circuit may be different from the first electrical circuit. The second electrical circuit and the first electrical circuit may share one or more electrical components. The second electrical circuit may comprise an electrical path (e.g., a conductive path), one or more switches controlling the electrical circuit, and/or any other suitable or desired electrical circuit components. The second electrical circuit may be configured to provide energy (e.g., electricity) from signal generator 70 to the one or more electrical contacts proximate bay 20 of housing 10. For example, the second electrical circuit may be configured to provide one or more stimulus signals from signal generator 70 to deployment unit 100 via electrical contacts coupling housing 10 to deployment unit 100. As a further example, the second electrical circuit may be configured to provide one or more electrical signals from signal generator 70 to one or more exposed terminals on deployment end 14. The exposed terminals may be configured to provide a local delivery (e.g., a local stun) to a target. In some embodiments, the second electrical circuit may comprise one or more capacitors configured to store (e.g., accumulate) the energy received from power supply 50 and discharge the stored energy to provide an electrical signal and/or stimulus signal. In some embodiments, the second electrical circuit may comprise one or more switches and/or other suitable or desired electrical circuit components configured to control the provision of energy from the one or more capacitors.

In various embodiments, a deployment unit 100 may comprise a propulsion system 80 and a plurality of projectiles, such as, for example, a first projectile 90 and a second projectile 95. Deployment unit 100 may comprise any suitable or desired number of projectiles, such as, for example, two projectiles, three projectiles, ten projectiles, and/or any other desired number of projectiles.

In various embodiments, propulsion system 80 may be coupled to, or in communication with, each projectile in deployment unit 100. In various embodiments, deployment unit 100 may comprise a plurality of propulsion systems 80, with each propulsion system 80 coupled to, or in communication with, one or more projectiles. Propulsion system 80 may comprise any device, propellant (e.g., air, gas, etc.), primer, or the like capable of providing a propulsion force in deployment unit 100. The propulsion force may include an increase in pressure caused by rapidly expanding gas within an area or chamber. The propulsion force may be applied to projectiles 90, 95 in deployment unit 100 to cause the deployment of projectiles 90, 95. Propulsion system 80 may provide the propulsion force in response to deployment unit 100 receiving the ignition signal.

In various embodiments, the propulsion force may be directly applied to one or more projectiles 90, 95. For example, the propulsion force may be provided directly to first projectile 90 or second projectile 95. Propulsion system 80 may be in fluid communication with projectiles 90, 95 to provide the propulsion force. For example, the propulsion force from propulsion system 80 may travel within a housing or channel of deployment unit 100 to one or more projectiles 90, 95. The propulsion force may travel via a manifold in deployment unit 100.

In various embodiments, the propulsion force may be provided indirectly to first projectile 90 and/or second projectile 95. For example, the propulsion force may be provided to a secondary source of propellant within propulsion system 80. The propulsion force may launch the secondary source of propellant within propulsion system 80, causing the secondary source of propellant to release propellent. A force associated with the released propellant may in turn provide a force to one or more projectiles 90, 95. A force generated by a secondary source of propellent may cause projectiles 90, 95 to be deployed from the deployment unit 100 and CEW 1.

In various embodiments, each projectile 90, 95 may comprise any suitable type of projectile. For example, one or more projectiles may be or include an electrode (e.g., an electrode dart), an entangling projectile (e.g., a tether-based entangling projectile, a net, etc.), a payload projectile (e.g., comprising a liquid or gas substance), or the like. A projectile may include a spear portion, designed to pierce or attach proximate a tissue of a target in order to provide a conductive electrical path between the electrode and the tissue, as previously discussed herein. For example, projectiles 90, 95 may each include a respective electrode. Projectiles 90, 95 may be deployed from deployment unit 100 at the same time or substantially the same time. Projectiles 90, 95 may be launched by a same propulsion force from a common propulsion system 80. Projectiles 90, 95 may also be launched by one or more propulsion forces received from one or more propulsion systems 80. Deployment unit 100 may include an internal manifold configured to transfer a propulsion force from propulsion system 80 to one or more projectiles 90, 95.

In various embodiments, signal generator 70 may be in electrical series with deployment unit and each projectile 90, 95. For example, signal generator 70 may be in electrical series with one or more electrical contacts (e.g., a handle contact, a handle electrical contact, etc.) disposed within bay 20 of handle 10. The electrical contact may be at least partially exposed within bay 20. In response to deployment unit 100 being inserted within bay 20, the electrical contact may engage (e.g., electrically couple to) one or more electrical contacts or features of deployment unit 100 (e.g., a deployment unit contact, a deployment unit electrical contact, etc.). Propulsion system 80 may be in electrical series with the one or more electrical contacts or features of deployment unit 100. Each projectile 90, 95 may be in electrical series with the one or more electrical contacts or features of deployment unit 100.

Signal generator 70 may be configured to provide one or more electrical signals to deployment unit 100 via the one or more electrical contacts. For example, signal generator 70 and/or processing circuit 50 may control provision of electrical signals to deployment unit 100, via the electrical contact. Signal generator 70 and/or processing circuit 50 may control provision of electrical signals by enabling and/or disabling an electrical connection. The electrical connection may define the electrical coupling between signal generator 70 and the electrical contact. Signal generator 70 and/or processing circuit 50 may enable and/or disable the electrical connection using any suitable technique or process, such as, for example, by selectively providing electrical signals, opening and/or closing circuits or switches, and/or the like. In some embodiments, providing an electrical signal may include providing a low voltage detection signal, an ignition signal, a stimulus signal, and/or the like.

In various embodiments, control interface 45 of CEW 1 may comprise, or be similar to, any control interface disclosed herein. In various embodiments, control interface 45 may be configured to control selection of firing modes in CEW 1. Controlling selection of firing modes in CEW 1 may include disabling firing of CEW 1 (e.g., a safety mode, etc.), enabling firing of CEW 1 (e.g., an active mode, a firing mode, an escalation mode, etc.), controlling deployment of a projectile, and/or similar operations, as discussed further herein. In various embodiments, control interface 45 may also be configured to perform (or cause performance of) one or more operations that do not include the selection of firing modes. For example, control interface 45 may be configured to enable the selection of operating modes of CEW 1, selection of options within an operating mode of CEW 1, or similar selection or scrolling operations, as discussed further herein.

Control interface 45 may be located in any suitable location on or in housing 10. For example, control interface 45 may be coupled to an outer surface of housing 10. Control interface 45 may be coupled to an outer surface of housing 10 proximate trigger 40 and/or a trigger guard of housing 10. Control interface 45 may be electrically, mechanically, and/or electronically coupled to processing circuit 50. In various embodiments, in response to control interface 45 comprising electronic properties or components, control interface 45 may be electrically coupled to power supply 60. Control interface 45 may receive power (e.g., electrical current) from power supply 60 to power the electronic properties or components.

Control interface 45 may be electronically or mechanically coupled to trigger 40. For example, and as discussed further herein, control interface 45 may function as a safety mechanism. In response to control interface 45 being set to a “safety mode,” CEW 1 may be unable to launch electrodes from deployment unit 100. For example, control interface 45 may provide a signal (e.g., a control signal) to processing circuit 50 instructing processing circuit 50 to disable deployment of electrodes from deployment unit 100. As a further example, control interface 45 may electronically or mechanically prohibit trigger 40 from activating (e.g., prevent or disable a user from depressing trigger 40; prevent trigger 40 from launching an electrode; etc.).

Control interface 45 may comprise any suitable electronic or mechanical component capable of enabling selection of firing modes. For example, control interface 45 may comprise a fire mode selector switch, a safety switch, a safety catch, a rotating switch, a selection switch, a selective firing mechanism, and/or any other suitable mechanical control. As a further example, control interface 45 may comprise a slide, such as a handgun slide, a reciprocating slide, or the like. As a further example, control interface 45 may comprise a touch screen, user interface or display, or similar electronic visual component.

The safety mode may be configured to prohibit deployment of a projectile from deployment unit 100. For example, in response to a user selecting the safety mode, control interface 45 may transmit a safety mode instruction to processing circuit 50. In response to receiving the safety mode instruction, processing circuit 50 may prohibit deployment of a projectile from deployment unit 100. Processing circuit 50 may prohibit deployment until a further instruction is received from control interface 45 (e.g., a firing mode instruction). As previously discussed, control interface 45 may also, or alternatively, interact with trigger 40 to prevent physical activation of trigger 40. In various embodiments, the safety mode may also be configured to prohibit deployment of a stimulus signal from signal generator 45, such as, for example, a local delivery.

The firing mode may be configured to enable deployment of one or more projectiles from deployment unit 100 in CEW 1. For example, and in accordance with various embodiments, in response to a user selecting the firing mode, control interface 45 may transmit a firing mode instruction to processing circuit 50. In response to receiving the firing mode instruction, processing circuit 50 may enable deployment of a projectile from deployment unit 100. In that regard, in response to trigger 40 being activated, processing circuit 50 may cause the deployment of one or more projectiles. Processing circuit 50 may enable deployment until a further instruction is received from control interface 45 (e.g., a safety mode instruction). As a further example, and in accordance with various embodiments, in response to a user selecting the firing mode, control interface 45 may also mechanically (or electronically) interact with trigger 40 of CEW 1 to enable activation of trigger 40.

In various embodiments, CEW 1 may comprise other modes operable into by control interface 45. For example, CEW 1 may comprise modes including a training mode, a manufacturing mode, a functional test mode, a stealth mode, a virtual reality mode, and/or the like. In these modes, one or more features or components of CEW 1 may be enabled or disabled compared to the standard firing mode and/or safety mode. For example, in the training mode a provision of a stimulus signal may be disabled. As a further example, in the stealth mode audio and/or light components may be disabled. As a further example, in the virtual reality mode, signals for deploying cartridges and/or provisional of a stimulus signal may be disabled.

In various embodiments, CEW 1 may further comprise one or more user interfaces. A user interface may be configured to receive an input from a user of CEW 1 and/or transmit or provide an output to the user of CEW 1. A user interface may be located in any suitable location on or in housing 10. For example, a user interface may be coupled to an outer surface of housing 10, or extend at least partially through the outer surface of housing 10. A user interface may be electrically, mechanically, and/or electronically coupled to processing circuit 50. In various embodiments, in response to a user interface comprising electronic or electrical properties or components, the user interface may be electrically coupled to power supply 60. The user interface may receive power (e.g., electrical current) from power supply 60 to power the electronic properties or components.

In various embodiments, a user interface may comprise one or more components configured to receive an input from a user. For example, a user interface may comprise one or more of an audio capturing module (e.g., microphone) configured to receive an audio input, a visual display (e.g., touchscreen, LCD, LED, etc.) configured to receive a manual input, a mechanical interface (e.g., button, switch, etc.) configured to receive a manual input, and/or the like.

In response to the interfacing with the compliant material, the compliant material may be configured to deform, displace, compress, flex, and/or the like between the outer surface of the deployment unit and the inner surface of the bay.

The compliant material may be configured to deform, displace, compress, flex, and/or the like before, during, and/or after deployment of the deployment unit (e.g., launch of projectiles from the deployment unit). For example, the compliant material may be configured to deform, displace, compress, flex, and/or the like before, during, and/or after deployment of the deployment unit (e.g., against the outer surface of the deployment unit and the inner surface of the bay). As a further example, the compliant material may be configured to deform, displace, compress, flex, and/or the like during deployment of the deployment unit (e.g., in response to receiving recoil forces from the deployment). In that regard, the compliant material may be configured to deform, displace, compress, flex, and/or the like in response to receiving a first force (e.g., compression force) before and/or after deployment of the deployment unit and/or in response to receiving a second force (e.g., recoil force, compression force, etc.) during deployment of the deployment unit.

In various embodiments, the compliant material may be configured to at least partially receive a recoil force during deployment of a deployment unit. The compliant material may be positioned and configured to at least partially receive the recoil force in response to a deployment of the deployment unit. For example, the compliant material may cushion and/or absorb along the firing axis in opposition to the recoil force. At least partially receiving a recoil force during deployment may dampen the recoil force. At least partially receiving a recoil force during deployment may improve accuracy of projectiles deployed from the deployment unit.

In various embodiments, the compliant material may be configured to apply increased normal force between the deployment unit and the CEW handle. The compliant material may be positioned and configured to apply an increased normal force between the outer surface of the deployment unit and the inner surface of the bay. The compliant material may be configured to provide a higher friction coefficient between the deployment unit and the CEW handle compared to a deployment unit that does not interface with a compliant material. In that regard, the compliant material may be configured to improve drop performance of the CEW and may be configured to provide a more robust installation of the deployment unit into the CEW handle.
