Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority benefit of U.S. Provisional Patent Application No. 63/641,460, filed on May 2, 2024, the content of which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

The disclosure relates generally to an archery targeting system and, more particularly, to an archery sight; having a detachable range-finding electronics module and connect/disconnect system.

BACKGROUND

Archery sights have historically been comprised of a mounting system, aiming pin alignment system, and an aiming pin housing. The mounting system allows the archery sight to be fixed to the frame of a bow. Many existing mounting systems do not allow the archery sight to have any degrees of freedom; however, a few allow the archery sight to be adjusted in the z-axis direction using a captured sliding mount system. U.S. Pat. No. 7,832,109 is an example of this adjustable technology. This design allows the user to adjust the sight picture of the archery sight and allows the archery sight to be easily detached from the frame of the bow.

The aiming pin alignment system of a fixed-pin archery sight is a 2-axis adjustment system that allows the user to align the pins horizontally (x-axis) and vertically (y-axis), resulting in a more accurate shot.

The aiming pin housing integrates an annular shaped frame, aiming pins, and an aiming pin adjustment system. Traditionally, the aiming pins integrate fiber optic fibers to serve as aiming reticles. A fixed-pin archery sight comprises of a plurality of fiber optic aiming pins, aligned in a vertically stacked orientation. Each pin is vertically adjustable (y-axis) using the aiming pin adjustment system, and is sighted in for a specific range. For example, the pins of a four-pin archery sight might be calibrated for target distances of 20, 30, 40, and 50 yards. The frame of the housing has the utility of protecting the aiming pins from damage and provides a place for the aiming pins and other instruments to be secured to the archery sight.

Contemporary archery sights incorporate additional instruments such as a bubble level, a fiber optic aiming pin illuminating light, and a cant indicator. U.S. Pat. No. 7,921,570 discloses the attributes of a cant indicator.

When using a fixed-pin archery sight, the user is required to either actively measure the distance to the target or accurately guess the distance to make an accurate shot. Because some targets may move while performing a shot sequence, accurately guessing the distance to a target can be challenging. In response to this challenge, multiple bow sights have been created that integrate a rangefinder, allowing the user to make a more accurate shot. Examples of such range-finding archery sights are disclosed in U.S. Pat. Nos. 8,316,551, 8,739,419, and 11,022,403.

U.S. Pat. No. 8,316,551 discloses the use of a rangefinder, inclinometer, processor, manually actuated trigger button, LEDs, and an anemometer in its version of a range-finding archery sight. The user presses the trigger button to start the active ranging process. The inclinometer measures the slope angle of the archery shot, and the anemometer measures the wind strength and direction. The archery sight's processor receives inputs from these sensors to calculate a more accurate target distance calculation and allows the user to actively adjust for wind strength and direction. After calculating an accurate target distance, the processor illuminates one or more light emitting diodes (LEDs) that are aligning in a vertically and horizontally stacked orientation within the aiming pin housing. Once illuminated, these LEDs are employed as aiming reticles to make an accurate shot. In addition to these attributes, the archery sight also stores one or more arrow profiles to further account for arrow and broadhead weight and drag characteristics. The electronics of this archery sight are fully integrated into the archery sight and cannot be easily removed. Finally, as designed, this archery sight is not functional if the electronics were removed, or if the archery sight lost power, making the sight not functional as an archery targeting system.

U.S. Pat. No. 11,022,403 discloses the use of a ranging module, projector, processor, memory, ambient light sensor, user interface, and arrow profiles in its version of a range-finding archery sight. The processor receives inputs from the ranging module to calculate the target distance and sends signals to the projector to display one or more aiming reticles. The projector uses one or more lasers and a mirrored system to project one or more digital aiming reticles onto a heads-up display. The projector system moves the aiming reticle vertically on the display based on the calculated target distance, giving the user an aiming point to make an accurate shot. The archery sight can store multiple arrow profiles in memory, which the processor uses to account for arrow weight and drag characteristics. If the archery sight is close to running out of power, the archery sight will project a plurality of digital fixed aiming reticles onto the heads-up display for a limited amount of time. Once the power fully runs out, the archery sight is not functional as an archery targeting system. Finally, the electronics are integrated into the archery sight, making it difficult to remove the electronics.

U.S. Pat. No. 8,739,419 discloses the use of a laser rangefinder, processor, power supply, trigger, and display in conjunction with a traditional fixed-pin archery sight. The user presses the trigger button to start the active ranging process. The laser rangefinder actively calculates the distance to the target, and the processor displays the distance on a backlit display. After the distance is displayed, the user reads the display and aligns the appropriate fiber optics aiming pin(s) with the target to make an accurate shot. Unlike the range-finding archery sights of U.S. Pat. Nos. 8,316,551 and 11,022,403, the range finding archery sight disclosed in U.S. Pat. No. 8,739,419 is still functional without the electronics, or if the electrical package lost power. However, like the other range-finding archery sights, the electronics are integrated into the archery sight and cannot be easily detached from the archery sight.

The contemporary range-finding archery sights discussed above address the challenge of accurately guessing a target's distance; however, U.S. state regulations have presented additional challenges for the use of these contemporary technologies. Since these designs have become available, multiple states have passed hunting regulations that outlaw the use of archery sights that integrate electronics and/or rangefinders that aid a hunter in making a more accurate shot. Though some states have passed regulations outlawing the technology, most U.S. states still allow the use of the new technology. In addition to the new hunting regulations, the use of range-finding archery sights is typically illegal in competitive archery.

The challenges discussed above make it difficult to use existing range-finding archery sights in many situations. The current designs do not allow a user to remove the electronics that are fully integrated into the archery sight when hunting in a state that restricts the use of range-finding archery sights, or when participating in an archery competition. If the electronics are fully removed, two of the three designs discussed above would become non-functional as archery targeting systems. Furthermore, these restrictions and challenges potentially require the user to purchase multiple archery sights to comply with all rules and regulations that apply to the user's situation while using a bow.

SUMMARY

The following introduces a selection of concepts in a simplified form in order to provide a foundational understanding of some aspects of the present disclosure. The following is not an extensive overview of the disclosure, and is not intended to identify key or critical elements of the disclosure or to delineate the scope of the disclosure. The following merely presents some of the concepts of the disclosure as a prelude to the more detailed description provided thereafter.

The present disclosure relates generally to an archery sight that includes a fixed-pin archery sight, detachable range-finding electronics module, and connect/disconnect system.

The archery sight with detachable range-finding electronics module disclosed herein addresses all of the challenges involved with using the contemporary range-finding archery sights discussed above by coupling a fixed-pin archery sight with a detachable range-finding electronics module and connect/disconnect system. The electronics associated with the archery sight with detachable range-finding electronics module are integrated in the detachable range-finding electronics module, which is connected to the fixed-pin archery sight via the connect/disconnect system. Depending on the shooting situation, the detachable range-finding electronics module can be installed on, or remove from, the fixed-pin archery sight, complying with all rules and regulations. Furthermore, the archery sight with detachable range-finding electronics module of the present disclosure allows the archery sight to remain functional when the electronics are removed, or in the case when the detachable range-finding electronics module loses power.

An additional feature that sets the archery sight with detachable range-finding electronics module of the present disclosure apart from contemporary range-finding archery sights is the use of wireless technology for the user interface and the ranging trigger. The use of wireless technology in the ranging trigger provides more trigger placement options. The flexibility of a wireless trigger can also mitigate the problem of canting the bow while using the trigger design of the contemporary range-finding archery sights. By reducing the potential of canting the bow, the wireless ranging trigger design increases the accuracy of the archery shot.

In an embodiment, the fixed-pin archery sight is secured to the frame of a bow using a detachable mounting system. The aiming pin housing, located on the fixed-pin archery sight, holds a plurality of fiber optic aiming pins, creating a sight picture.

In an embodiment, the detachable range-finding electronics module contains the electronics required for the archery sight with detachable range-finding electronics module. The connect/disconnect system allows the detachable range-finding electronics module to be installed on, or removed from, the fixed-pin archery sight. Among the electronics housed in the detachable range-finding electronics module are a processor, rangefinder sensor, a plurality of illuminating elements, ranging trigger, power source, global positioning system (GPS) sensor, accelerometer, and visible calibration laser.

In an embodiment, the processor is configured to receive inputs from the ranging trigger, to start and stop the ranging process, and from the rangefinder sensor, to calculate the ranged distance to a target. Once the actual distance to the target is calculated, the processor illuminates one or more illuminating elements, which in turn illuminates the respective fiber optic aiming pins on the fixed-pin archery sight.

When the detachable range-finding electronics module is removed, the fiber optic aiming pins are illuminated by ambient light, returning the archery sight to a traditional fixed-pin archery sight. In other embodiments of the archery sight, the detachable range-finding electronics module incorporates one or more displays, display and parameter inputs, an illuminating element luminosity calibrator, a wireless communication module, one or more cameras, memory, and a timer switch to enhance the functionality of the archery sight.

Other features and advantages of the present disclosure will become apparent from the more detailed description given below. However, it should be understood that the following detailed description and specific examples, while indicating embodiments of the methods, systems, and apparatuses, are given by way of illustration only, since various changes and modifications within the spirit and scope of the concepts disclosed herein will become apparent to those skilled in the art from the following detailed description.

Embodiments of the present disclosure and their advantages are best understood by referring to the detailed description that follows. It should be appreciated that like reference numbers are used to identify like elements illustrated in one or more of the figures, wherein showings therein are for purposes of illustrating embodiments of the present disclosure and not for purposes of limiting the same.

DETAILED DESCRIPTION OF SOME EMBODIMENTS

Various examples and embodiments of the present disclosure will now be described. The following description provides specific details for a thorough understanding and enabling description of these examples. One of ordinary skill in the relevant art will understand, however, that one or more embodiments described herein may be practiced without many of these details. Likewise, one skilled in the relevant art will also understand that one or more embodiments of the present disclosure can include other features and/or functions not described in detail herein.

In an embodiment, an archery sight with detachable range-finding electronics module is comprised of a fixed-pin archery sight 94, a detachable range-finding electronics module 1, and a connect/disconnect system 95 (sometimes referred to herein as a “connection system”). The fixed-pin archery sight 94 includes the basic non-electronic tools and features that aid in completing an accurate archery shot. The detachable range-finding electronics module 1 houses the electronics necessary to enhance the archery sight. The connect/disconnect system 95 allows the detachable range-finding electronics module 1 to be secured to, and removed from, the fixed-pin archery sight 94.

FIG. 1A illustrates an embodiment of a fixed-pin archery sight 94 with a sliding frame mount. The fixed-pin archery sight 94 of this embodiment is comprised of a mounting bracket 2, sliding mount arm 3, clamping finger 4, horizontal alignment bar 5, vertical adjustment fixture 6, aiming pin housing 7, a plurality of aiming pins 8, a plurality of fiber optic fibers 9 with opaque shielding 10, a plurality of fiber optic channels 11, and a plurality of fiber optic repositories 12.

FIG. 1D is a side plane view of the fixed-pin archery sight shown in FIG. 1A, illustrating an embodiment of the mounting bracket 2. The mounting bracket 2 bolts to the frame 13 of a bow using a common bolt pattern and is designed to hold and secure the sliding mount arm 3 using a dovetail feature and a set screw 14. FIG. 2A illustrates a fixed-pin archery sight 94 with a sliding frame mount mounted to the frame 13 of a compound bow, according to an embodiment.

The sliding mount arm 3 allows the archery sight to be adjusted along the z-axis, adjusting the sight picture. FIG. 1C illustrates the sight picture of an embodiment of a fixed-pin archery sight 94. As the sliding mount arm 3 is slid further back in the mounting bracket 2, the aiming pins 8 appear to be larger on a distant target 15 (e.g., as shown in FIG. 14). As the sliding mount arm 3 is slid further forward in the mounting bracket 2, the aiming pins 8 appear to be smaller on the distant target 15. The sight picture is comprised of the appearance of the aiming pins 8 on the distant target 15 and how much of the distant target 15 and the surrounding area is seen within the annular shape of the aiming pin housing 7.

FIG. 3 illustrates an embodiment of a static fixed-pin archery sight 96, which incorporates a static frame mount 16. In this embodiment, the static frame mount 16 replaces the sliding mount arm 3 and mounting bracket 2 features of the embodiment that incorporates a sliding frame mount, as described above and shown in FIGS. 1A-1D. The sight picture may not be adjustable along the z-axis in this embodiment.

As shown in FIG. 1D, the clamping finger 4 enables the sliding mount arm 3, or static frame mount 16, to be secured to the horizontal alignment bar 5, in an embodiment. The clamping finger 4 is tightened around the horizontal alignment bar 5 using a screw 17, fixing the sliding mount arm 3, or static frame mount 16, to the horizontal alignment bar 5.

As shown in FIG. 1B, the horizontal alignment bar 5 allows the aiming pins 8 to be adjusted along the x-axis, in an embodiment. This x-axis adjustment of the aiming pins 8 adjusts the archery shot in the windage direction (along the x-axis).

FIG. 4A illustrates an embodiment of a micro adjusting fixed-pin archery sight 97, which integrates a horizontal alignment bar 5 that includes an integrated horizontal adjustment screw 18. In this embodiment, the sliding frame mount, as described above and shown in FIGS. 1A-1D, is attached to the integrated horizontal adjustment screw 18 using a traveler. As the integrated horizontal adjustment screw 18 is rotated in the clockwise and counterclockwise directions, the horizontal alignment bar 5 moves in and out along the x-axis.

As shown in FIGS. 1B and 1D, the vertical adjustment fixture 6 incorporates slots 19, where a plurality of aiming pins 8 are attached and secured in a vertically stacked orientation, in an embodiment. FIG. 1C illustrates a plurality of aiming pins 8 in a vertically stacked orientation inside an embodiment of an aiming pin housing 7. The slots 19 in the vertical adjustment fixture 6 allow the aiming pins 8 to be adjusted in the vertical direction (y-axis) so that each aiming pin 8 can be calibrated for its intended target distance.

FIG. 1B illustrates an embodiment of a horizontal alignment bar 5 that is secured to the vertical adjustment fixture 6 using a screw 20 that tightens the horizontal alignment bar 5 around the vertical adjustment fixture 6. In this embodiment, a dovetail slot feature is integrated into the horizontal alignment bar 5 in the shape of a feature on the vertical adjustment fixture 6. Loosening the securing screw 20 in this embodiment allows the vertical adjustment fixture 6 to be adjusted in the vertical (y-axis) direction, giving additional room for the aiming pins 8 to be adjusted in the y-axis.

FIG. 4B illustrates an embodiment of a micro adjusting fixed-pin archery sight 97, which integrates a vertical adjustment fixture 6 that includes an integrated vertical adjustment screw 21. In this embodiment, the horizontal alignment bar 5 is attached to the integrated vertical adjustment screw 21 using a traveler. As the integrated vertical adjustment screw 21 is rotated in the clockwise and counterclockwise directions, the vertical adjustment fixture 6 moves up and down along the y-axis, also moving the aiming pins 8 along the y-axis.

In another embodiment, the vertical adjustment fixture 6 and aiming pin housing 7 are integrated into each other as one piece. In this embodiment, the vertical adjustment fixture 6 is not secured to the aiming pin housing 7 using screws or other means.

As shown in FIG. 1C, the aiming pin housing 7 is a shroud that protects the aiming pins 8 from damage, in an embodiment. In this embodiment, the aiming pin housing 7 also allows additional tools to be integrated into the fixed-pin archery sight 94. These additional tools can include a level indicator 22 and cant indicator 23. Furthermore, the fiber optic channels 11 and fiber optic repositories 12 features of the fixed-pin archery sight 94 are integrated into the aiming pin housing 7, in an embodiment.

As shown in FIG. 1C, the level indicator 22 aids the user in keeping the bow frame 13 oriented in a vertical position that is perpendicular to the x-z plane, in an embodiment. This ensures that the bow is not canted in the roll direction (around z-axis) during an archery shot. In this embodiment, the level indicator 22 is a bubble level. The bubble level contains an air bubble within a liquid filled transparent tube. When the bow frame 13 is held perpendicular to the x-z plane, the air bubble becomes oriented between two indica that are centered on the transparent tube. In this orientation, the level indicator 22 informs the user that the bow frame 13 is being held in a vertical position that is perpendicular to the x-z plane. In this embodiment, the level indicator 22 is attached to the aiming pin housing 7 in a horizontal position, adjacent to the aiming pins 8.

FIG. 5 illustrates another embodiment of a level indicator 22 that is integrated into an embodiment of a detachable range-finding electronics module 1. This embodiment uses an accelerometer 24 and a display 25 to display the orientation of the bow frame 13. The accelerometer 24 measures the angle at which the detachable range-finding electronics module 1 is being held in the roll (around z-axis) direction, and the display 25 displays the detachable range-finding electronics module's 1 orientation using an indica. In this embodiment, the accelerometer 24 is secured inside the detachable range-finding electronics module 1. The display 25 is attached to the outside of the detachable range-finding electronics module 1 in an orientation that is rearward facing to the user and adjacent to the aiming pin housing 7, in an embodiment.

An additional embodiment of the aiming pin housing 7 integrates a cant indicator 23. The cant indicator 23 allows the user to determine if the bow frame 13 is being canted in the pitch (around x-axis) and/or yaw (around y-axis) directions during the process of an archery shot. In one embodiment, the cant indicator incorporates a display indica and a fiber optic fiber 9. The fiber optic fiber 9 backlights the display indica. For calibration purposes, the indica is adjustable in the x and y-axes. The cant indicator 23 is oriented adjacent to the aiming pins 8. Additional embodiments of the cant indicator 23 are described in U.S. Pat. No. 7,921,570 B1.

FIG. 5 illustrates another embodiment of a cant indicator 23 that is integrated into an embodiment of a detachable range-finding electronics module 1. This embodiment uses an accelerometer 24 and a display 25 to display the orientation of the detachable range-finding electronics module 1, much like the embodiment of a digital level indicator 22 discussed above. In this embodiment, the accelerometer 24 measures the angles at which the detachable range-finding electronics module 1 is being held in the pitch (around x-axis) and yaw (around y-axis) directions, and the display 25 displays the detachable range-finding electronics module's 1 orientation using an indica.

As shown in FIG. 1B, the fiber optic channels 11 secure the shielded fiber optic fibers 9 to the aiming pin housing 7 before the fiber optic fibers 9 enter their respective fiber optic repository 12, in an embodiment. In this embodiment, the fiber optic channels 11 are integrated into the top face of the aiming pin housing 10 in a way that allows the top of the shielded fiber optic fibers 9 to sit below, or level with, the top surface of the aiming pin housing 7. This allows the top face of the aiming pin housing 7 to sit flush with the bottom face of the detachable range-finding electronics module 1 when the detachable range-finding electronics module 1 is installed on the fixed-pin archery sight 94.

As shown in FIG. 1B, the fiber optic repositories 12 allow the excess unshielded fiber optic fibers 9 to be wound around posts 26 in a pattern that increases the illuminating surface area of the fiber optic fibers 9, increasing the amount of light channeled to the tip of the fiber optic fibers 9 in the aiming pins 8, in an embodiment. In this embodiment, the fiber optic repositories 12 also secure the fiber optic fibers 9 to the aiming pin housing 7. The number of fiber optic repositories 12 is proportionate to the number of aiming pins 8 integrated into the fixed-pin archery sight 94. The fiber optic repositories 12 are spaced and oriented in a way where the illuminating elements 27 that are integrated into the detachable range-finding electronics module 1 are positioned directly above, and in-line with, each illuminating element's 15 respective aiming pin's 8 fiber optic fiber 9 when the detachable range-finding electronics module 1 is attached to the fixed-pin archery sight 94. For example, the 20-yard illuminating element 15 is positioned directly above, and in-line with, the 20-yard aiming pin 8 fiber optic repository 12. In this embodiment, the fiber optic repositories 12 are integrated into the top face of the aiming pin housing 7 in a way where the top face of the aiming pin housing 7 sits flush with the bottom face of the detachable range-finding electronics module 1 when the detachable range-finding electronics module 1 is installed on the fixed-pin archery sight 94.

FIG. 6C is a detailed section plane view of an embodiment of a fiber optic repository 12 that utilizes an embodiment of a securing feature 98 that includes a securing clamp 28 and a tightening screw 29. In this embodiment, the fiber optic fibers 9 are secured to their respective fiber optic repository 12 using the securing feature 98 described above. Each fiber optic repository 12 integrates a securing feature 98. In this embodiment, the securing clamp 28 is in the shape of the fiber optic repository 12 and fits around the posts 26 that the fiber optic fibers 9 are wound around. The securing clamp 28 is transparent, allowing ambient light and light from the illuminating elements 27 to pass through to illuminate the fiber optic fibers 9. The tightening screw 29 exerts a downward force on the securing clamp 28 as the tightening screw 29 is screwed into the top of the aiming pin housing 7, tightening the securing clamp 28 onto the fiber optic fiber 9 and preventing the fiber optic fiber 9 from becoming unsecured from the fiber optic repository 12.

FIG. 7C is a detailed section plane view of an embodiment of a fiber optic repository 12 that incorporates a simple securing feature 99, which integrates a securing post 30. In this embodiment, the securing post 30 incorporates through hole 31 and countersunk hole 32 features. The securing post 30 has a through hole 31 that starts at the top of the securing post 30 and exits out the side of the securing post 30 in a multitude of directions. Additionally, a countersunk hole feature 32 is located at the top of the securing post 30. The securing post 30 allows a fiber optic fiber 9 to be threaded through the securing post 30, entering the side of the securing post 30 and exiting out the top. This embodiment orients the tip of the fiber optic fiber 9 parallel to its respective illuminating element 15, improving aiming pin 8 illumination.

FIG. 1C illustrates an embodiment of the vertically stacked aiming pins 8 installed on an embodiment of a fixed-pin archery sight 94. Each aiming pin 8 holds a fiber optic fiber 9 which channels visible light to the tip of the aiming pin 8. The aiming pin 8 holds its fiber optic fiber 9 in an orientation where the end of the fiber optic fiber 9 is approximately parallel to the user's eye 33 when the user is at draw with the bow. In this embodiment, the fiber optic fibers 9 are threaded through the aiming pins 8 and routed to their respective fiber optic repositories 12, located on the top face of the aiming pin housing 7.

FIG. 8 is a plane break view of an embodiment of a fiber optic fiber 9. As discussed above, the fiber optic fiber 9 aids in channeling visible light to the tip of an aiming pin 8. In this embodiment, an opaque shielding 10 is used to shield the fiber optic fiber 9 from ambient light, reducing the amount of ambient light absorbed and channeled through each fiber optic fiber 9 while the detachable range-finding electronics module 1 is installed on the fixed-pin archery sight 94. In the embodiment illustrated in FIG. 8, the opaque shielding 10 is a heat shrink material. In another embodiment, the opaque shielding 10 is an opaque coating.

In another embodiment of the fixed-pin archery sight 94, the physical features of the aiming pins 8, aiming pin housing 7, and vertical adjustment fixture 6 act as the opaque shielding 10. In this embodiment, through holes are used to channel the fiber optic fibers 9 to their respective fiber optic repositories 12. Physical opaque material covers the fiber optic fibers 9 on all sides, preventing ambient light from illuminating the fiber optic fibers 9 in areas other than the fiber optic repositories 12.

As shown in FIGS. 10A-10C, the detachable range-finding electronics module 1 contains the electronics associated with the range-finding archery sight, in an embodiment. FIG. 9 illustrates the embodiment of this detachable range-finding electronics module 1 installed on an embodiment of a fixed-pin archery sight 94.

FIG. 11 is a schematic illustration of a basic embodiment of the electronics integrated in the detachable range-finding electronics module 1, in an embodiment. In this embodiment, a processor 34, rangefinder sensor 35, power source 36, ranging trigger 37, accelerometer 24, global positioning system (GPS) sensor 38, a plurality of illuminating elements 27, and a visible calibration laser 39 are contained in the detachable range-finding electronics module 1.

In the embodiment illustrated in FIG. 11, the processor 34 receives inputs from the rangefinder sensor 35, accelerometer 24, GPS sensor 38, and ranging trigger 37, calculates the actual distance 40 to the target 15, and determines which illuminating element(s) 27 should be illuminated based on the calculated actual distance 40 to the target 15. During the ranging process of an embodiment, the processor 34 modulates the illumination of the illuminating element 27 associated with the ranging pin; the top aiming pin 8 for example. In this embodiment, the processor 34 also illuminates a plurality of illuminating elements 27 in a static or modulating pattern in the cases where the processor 34 receives an error while calculating the actual distance 40 to the target 15, calculates the target 15 at an actual distance 40 greater than the calibrated distance of the furthest aiming pin 8, or calculates the target 15 at an actual distance 40 less than the calibrated distance of the closest aiming pin 8.

In this embodiment, illustrated in FIG. 11, the illuminating elements 27 are associated with fixed distances. For example, if the archery sight has four illuminating elements 27, the processor 34 could be permanently programmed to associate the calculated actual distances 40 of 20, 30, 40 and 50 yards to the illuminating elements 27. In this embodiment, the programming of variables in the processor 34 cannot be changed in a way that changes the associated calculated actual distances 40 of the illuminating elements 27. In the four aiming pin 8 configuration embodiment described above, the aiming pins 8 must be calibrated to set distances, for example, 20, 30, 40, and 50 yards.

In an embodiment, the processor 34 measures the voltage of the power source 36, where the embodiment of the power source 36 is in the form of a rechargeable battery. This allows the processor 34 to calculate the battery level, which is used to provide a battery level indicator 41. In an embodiment, when the battery level is displayed, the processor 34 uses the measured voltage of the rechargeable battery to determine which illuminating element(s) 27 should be illuminated. In this embodiment of the battery level indicator 41, the illuminating elements 27 communicate the battery level by illuminating the aiming pins 8 in a way that communicates the battery level in increments.

FIG. 12A is a plane view of an embodiment of a detachable range-finding electronics module 1 that uses a plurality of light emitting diodes (LEDs) as a battery level indicator 41, that are separate from the illuminating elements 27. When the battery level is displayed, the processor 34 uses the measured voltage of the rechargeable battery to determine which LED(s) to illuminate, communicating the battery level in increments.

FIGS. 5, 20, and 21 illustrate other embodiments of a battery level indicator 41, where the measured battery level is displayed on a display 25.

FIG. 13 is a plane view of an embodiment of a detachable range-finding electronics module 1 that illustrates the orientation of the rangefinder sensor 35 on the front of the detachable range-finding electronics module 1, where the rangefinder sensor 35 is pointed along the z-axis, towards the target 15. In this embodiment, the rangefinder sensor 35 is oriented adjacent to the aiming pins 8 when the detachable range-finding electronics module 1 is installed on the fixed-pin archery sight 94. The rangefinder sensor 35 actively calculates the ranged distance 42, shown in FIG. 14, to the target 15. In one embodiment, the rangefinder sensor 35 is a laser rangefinder sensor. In this embodiment, the laser rangefinder sensor actively emits a visible or nonvisible ranging beam 43 of light particles from the sensor's transmitter 44. To calculate the ranged distance 42 to the target 15, the laser rangefinder sensor 35 measures the round-trip time for the ranging beam 43 to return to the rangefinder sensor's 35 receiver 45. Dividing the round-trip time by two and multiplying by the speed of light calculates the ranged distance 42 to the target 15. In other embodiments, the rangefinder sensor 35 employs light detection and ranging (LIDAR), laser detection and ranging (LADAR), or radio frequency (RF) technology to calculate the ranged distance 42 to the target 15.

The power source 36 provides power to all electronics integrated in the detachable range-finding electronics module 1. In one embodiment, the power source 36 is made up of a single, or plurality, of rechargeable batteries.

FIG. 10A is a plane view of a detachable range-finding electronics module 1 that incorporates a rechargeable power source 36 and includes a charging port 68, in an embodiment. In this embodiment, the charging port 68 aids in recharging the power source 36 when the detachable range-finding electronics module 1 is not in use.

Shown in FIG. 10A, the charging indicator 69 provides information on the charging status of the rechargeable power source 36, in an embodiment. This could include the status on whether the power source 36 is still charging, and the current charge level of the rechargeable power source 36 while charging. In this embodiment, the charging indicator 69 is comprised of two LEDs. Charging status can be provided by statically illuminating or modulating the illumination of one or more LEDs.

FIG. 12A illustrates another embodiment of a charging indicator 69, where the charging indicator 69 makes use of a plurality of LEDs that are used for the battery level indicator 41 to display the charging status of the rechargeable power source 36.

In another embodiment of the charging indicator 69, the charging indicator 69 makes use of the plurality of illuminating elements 27, shown in FIG. 10C, used to illuminate the aiming pins 8 to display the charging status of the rechargeable power source 36.

FIG. 15 is a plane view of an embodiment of a detachable range-finding electronics module 1 that illustrates the orientation of a solar cell 46. In this embodiment, the power source 36 integrates with a solar cell 46, enabling the rechargeable battery to charge when other recharging methods are not available.

In another embodiment, the power source 36 is a single or plurality of replaceable non-rechargeable batteries.

As shown in FIG. 10A, the power switch 47 controls the supply of power to the electronics, in an embodiment. In this embodiment, the power switch 47 can be a toggle, rocker, or push-button switch.

FIG. 16 illustrates another embodiment of a power switch 47 that uses a piezoelectric sensor 48. In this embodiment, the piezoelectric sensor 48 is attached to one or more limbs 49 of the bow to determine when the detachable range-finding electronics module 1 should be powered on and off. In one embodiment, the piezoelectric sensor 48 is attached to the detachable range-finding electronics module 1 through a cable 50. In another embodiment, the piezoelectric sensor 48 can be detached from the detachable range-finding electronics module 1 by integrating a male connector 51 and female connector 108 into the detachable range-finding electronics module 1 and piezoelectric sensor 48 cable 50.

As shown in FIG. 2B, the ranging trigger 37 is used to start and stop the ranging process of the detachable range-finding electronics module 1, in an embodiment. In one embodiment, the ranging trigger 37 is a push button switch that is connected to the detachable range-finding electronics module 1 through a cable 50. In another embodiment, the ranging trigger 37 can be detached from the detachable range-finding electronics module 1 by integrating a male connector 51 and female connector 108 into the detachable range-finding electronics module 1 and ranging trigger 37 cable 50, shown in FIG. 2B.

FIG. 16 is a top perspective view of an embodiment of a detachable range-finding electronics module 1 that includes a piezoelectric sensor 48. In this embodiment the ranging trigger 37 uses a piezoelectric sensor 48 attached to one or more limbs 49 of the bow. The piezoelectric sensor 48 detects when the bow has been pulled back during the start of a shot sequence from the flex of the bow limbs 49, allowing the processor 34 to determine when to start the ranging process of the rangefinder sensor 35. In one embodiment, the piezoelectric sensor 48 is attached to the detachable range-finding electronics module 1 through a cable 50. In another embodiment, the piezoelectric sensor 48 can be detached from the detachable range-finding electronics module 1 by integrating a male connector 51 and female connector 108 into the detachable range-finding electronics module 1 and piezoelectric sensor 48 cable 50.

FIG. 17B is a detailed top perspective view of an embodiment of a ranging trigger 37 and detachable range-finding electronics module 1 that uses a wireless communications module 52. FIG. 18 is a schematic illustration of the electronics integrated in this embodiment of the detachable range-finding electronics module 1. FIG. 12B is a plane view of an embodiment of a detachable range-finding electronics module 1 that incorporates a wireless communications module 52. This embodiment of a ranging trigger 37 and detachable range-finding electronics module 1 allows the ranging trigger 37 to be placed anywhere that is preferred.

In one embodiment where the ranging trigger 37 and detachable range-finding electronics module 1 make use of a wireless communications module 52, the ranging trigger 37 and detachable range-finding electronics module 1 communicate through infrared (IR) sensors 53. In other embodiments, the ranging trigger 37 and detachable range-finding electronics module 1 communicate through Bluetooth® or WiFi.

The accelerometer 24 measures the angular orientation of the bow in the pitch (around x-axis), roll (around z-axis), and yaw (around y-axis) directions. As previously discussed above, these measurements can be used for displaying information with a digital level indicator 22 and cant indicator 23, in an embodiment. In another embodiment, pitch (around x-axis) angle measurements are used to calculate a more accurate actual distance 40 to the target 15.

FIG. 14 is an illustration that explains why an accelerometer 24 is necessary when using a rangefinder sensor 35 to measure the distance to a target 15. When measuring the distance to a target 15 using a rangefinder sensor 35, the rangefinder sensor 35 measures the direct line-of-sight distance to the target 15, which is the hypotenuse of the right triangle. If the target 15 is above or below the user in elevation, the bow must be angled up or down in the pitch (around x-axis) direction to align the correct aiming pin 8 with the target 15. In this orientation, the rangefinder sensor 35 measures the ranged distance 42, which is longer than the actual distance 40 to the target 15. The actual distance 40 to the target 15 is the horizontal distance to the target 15 with a pitch angle (θ) 54 of zero degrees. By using the pitch angle (θ) 54 measured by the accelerometer 24, the actual distance 40 to the target 15 can be calculated. The actual distance 40 is calculated using the following equation:

actual distance=ranged distance×cos(|θ|)

In an embodiment, the GPS sensor 38 integrated into the detachable range-finding electronics module 1 sends latitude and longitude data to the processor 34, allowing the processor 34 to enable and disable the range-finding capabilities of the detachable range-finding electronics module 1. In this embodiment, the GPS sensor 38 receives signals from a multitude of satellites or cellular towers to calculate the detachable range-finding electronics module's 1 latitude and longitude coordinates. The processor 34 receives the latitude and longitude data and determines whether the range-finding capabilities should be enabled or disabled based on other geospatial data.

Shown in FIG. 12A, a timer switch is integrated into the detachable range-finding electronics module 1 to determine when a timer should start and stop, in an embodiment. In this embodiment, the processor 34 calculates and stores the time that has elapsed since the detachable range-finding electronics module 1 was last installed on the fixed-pin archery sight 94. In the embodiment shown in FIG. 12A, the timer switch 55 is a plunger switch. In another embodiment, shown in FIG. 29, the timer switch 55 is comprised of an RFID tag 100 embedded in the fixed-pin archery sight 94, and an RFID scanner 101 integrated into the detachable range-finding electronics module 1. Finally, in another embodiment, the timer switch 55 is a magnetic switch.

In another embodiment of the detachable range-finding electronics module 1, the processor 34 receives information from an RFID tag 100, shown in FIG. 29, embedded in the fixed-pin archery sight 94, read by an RFID scanner 101 that is integrated into the detachable range-finding electronics module 1, enabling the processor 34 to determine whether the range-finding capabilities should be enabled or disabled. For example, if the data received from the RFID tag 100 embedded in the fixed-pin archery sight 94 does not match the identification stored in the non-volatile memory 56 of the detachable range-finding electronics module 1, the logic of the processor 34 determines that the range-finding capabilities should be disabled.

As shown in FIG. 10C, the illuminating elements 27 are oriented on the bottom face of the detachable range-finding electronics module 1, where the face of the detachable range-finding electronics module 1 mates with the top face of the aiming pin housing 7, in an embodiment. In this embodiment, the illuminating elements 27 are positioned in a way that allows each illuminating element 27 to be aligned with its respective fiber optic repository 12 when the detachable range-finding electronics module 1 is installed on the fixed-pin archery sight 94. The number of illuminating elements 27 is proportionate to the number of aiming pins 8. The illuminating elements 27 illuminate their respective aiming pin's 8 fiber optic fiber 9 with radiant light in the visible spectrum, illuminating the tip of the fiber optic fiber 9 in the aiming pin 8. One or more illuminating elements 27 illuminate the tip(s) of the aiming pin(s) 8 in a static or modulating pattern to convey target distance, operating status, or battery level information. In the embodiment shown in FIG. 10C, the illuminating elements 27 are LEDs. In another embodiment, the illuminating elements are visible light emitting lasers.

As shown in FIG. 10C, the illuminating element gasket 57, which surrounds each illuminating element 27 and its respective fiber optic repository 12, prevents radiant light from leaking over to other fiber optic repositories 12, preventing other aiming pins 8 from being inadvertently illuminated. This increases the accuracy of the information provided through the illumination of the aiming pins 8.

In another embodiment, the detachable range-finding electronics module 1 integrates a rangefinder sensor aiming calibration system 102. The rangefinder sensor aiming calibration system 102 allows the ranging beam 43 of the rangefinder sensor 35 to be adjusted in the pitch (around x-axis) and yaw (around y-axis) directions. The ability to adjust the direction that the ranging beam 43 is being emitted allows the rangefinder sensor 35 to calculate a more accurate ranged distance 42 to the target 15. FIG. 24A is a schematic illustration of a ranging beam 43 not aligned with the line-of-sight 67 on a target 15. FIG. 24B is a schematic illustration of a ranging beam 43 aligned with the line-of-sight 67, on a target 15. If the ranging beam 43 is not closely aligned with the line-of-sight 67 at distance, the ranging beam 43 could calculate the ranged distance 42 of an object other than the target 15. The rangefinder sensor aiming calibration system 102 ensures that the ranging beam 43 of the rangefinder sensor 35 is closely aligned with the line-of-sight 67 on a distant target 15.

FIGS. 25C and 25E are detailed section plane views of an embodiment of a detachable range-finding electronics module 1 that integrates a rangefinder aiming calibration system 102 that is comprised of a pivot point 70, and a multitude of plunger pin guides 71, plunger pins 72, plunger springs 73, traveler guides 74, travelers 75, adjustment screws 76, and captivating screws 77. This embodiment allows the rangefinder sensor 35 to be rotated in the pitch (around x-axis) and yaw (around y-axis) directions. The pivot point 70 fixes the rangefinder sensor 35 to the detachable range-finding electronics module 1 in the x-, y-, and z-axes, but allows the rangefinder sensor 35 to rotate in the pitch (around x-axis), roll (around z-axis), and yaw (around y-axis) directions. Two adjustment systems 103 are used to rotate the rangefinder sensor 35 in the pitch (around x-axis) and yaw (around y-axis) directions, one for each direction. In this embodiment, one adjustment system 103 is oriented along the x-axis, and the other is oriented along the y-axis.

As shown in FIGS. 25C and 25E, each adjustment system 103 includes a plunger pin guide 71, plunger pin 72, plunger spring 73, traveler guide 74, traveler 75, adjustment screw 76, and captivating screw 77, in an embodiment. The traveler guide 74 surrounds the traveler 75 and adjustment screw 76, and guides the traveler 75 to and from the rangefinder sensor 35. The traveler guide 71 has slots cut into its cylindrical shape, in the shape of features on the traveler 75, which prevent the traveler 75 from rotating. The traveler 75 is threaded on the inside of its cylindrical shape and mates with the threads of the adjustment screw 76. The traveler 75 is one of the features that provides a force onto the rangefinder sensor 35, rotating the sensor in either the pitch (around x-axis) or yaw (around y-axis) directions. The adjustment screw 76 is free to rotate and is what drives the traveler 75 in and out of the traveler guide 74. The captivating screw 77 captivates the adjustment screw 76 to the housing of the detachable range-finding electronics module 1. The captivating screw 77 also allows the adjustment screw 76 to be rotated from an external tool, outside of the detachable range-finding electronics module 1.

In the embodiment shown in FIGS. 25C and 25E, the plunger guide 71, plunger pin 72, and plunger spring 73 make up the subassembly of the rangefinder aiming calibration system 102 that exerts an opposite force onto the rangefinder sensor 35, in relation to the traveler 75. The plunger guide 71 holds the plunger spring 73 and plunger pin 73 in place, and guides the plunger pin 73 to the rangefinder sensor 35. The plunger spring 73 is a compression spring that allows the plunger pin 72 to retract when the traveler 75 is applying a greater force on the rangefinder sensor 35 compared to the force of the plunger spring 73, rotating the sensor in one direction. The plunger spring 73 also expands and generates a force onto the plunger pin 72 when the traveler 75 is retracted from the rangefinder sensor 35. This force is opposite of the force applied by the traveler 75 and allows the rangefinder sensor 35 to rotate in the opposite direction when the traveler 75 is retracted. The plunger pin 73 mates with the rangefinder sensor 35 and is what transfers the force of the plunger spring 73 to the rangefinder sensor 35.

In one embodiment of the rangefinder sensor aiming calibration system 102, a visible calibration laser 39 is incorporated, which emits a visible calibration beam 78. The laser is designed to be accurately aligned with the transmitter's 44 ranging beam 43 of the rangefinder sensor 35 in the x or y-axis. The visible calibration beam 78 allows the user to align the ranging beam 43 of the rangefinder sensor 35 using a visual reference, ensuring the accurate alignment of the ranging beam 43 with the line-of-sight 67 on a distant target 15. The visible calibration laser is attached to the outside of the detachable range-finding electronics module 1, in an embodiment.

FIG. 26A is a schematic illustration of one embodiment of a rangefinder sensor 35 that integrates a visible calibration laser 39. In this embodiment, the rangefinder sensor's 35 transmitter 44 and the visible calibration laser 39 are collocated adjacent to each other so that both beams exit the rangefinder sensor 35 at approximately the same point and direction.

FIG. 26B is a schematic illustration of an embodiment of a rangefinder sensor 35 that integrates a visible calibration laser 39 and one or more mirrors 79. In this embodiment, the mirrors 79 are used to reflect the ranging beam 43 and visible calibration beam 78 in a way where both beams are aligned with the line-of-sight 67 on a distant target 15. In this embodiment, the combination of the mirrors 79 and visible calibration laser 39 combine to make a mirrored rangefinder sensor aiming calibration system 104. The mirrors 79 can be adjusted in the pitch, and yaw directions, which changes the angle at which the ranging beam 43 and visible calibration beam 78 are reflected. This adjusts the azimuth (around the y-axis) and elevation (around the x-axis) angles at which the ranging beam 43 and visible calibration beam 78 exit the detachable range-finding electronics module 1.

FIG. 26C is a schematic illustration of an embodiment of a rangefinder sensor 35 that integrates a visible calibration laser 39 and a prism 80. In this embodiment, the prism 80 is used to refract the ranging beam 43 and visible calibration beam 78 in a way where both beams are aligned with the line-of-sight 67 on a distant target 15. In this embodiment, the combination of the prism 80 and visible calibration laser 39 combine to make a prismed rangefinder sensor aiming calibration system 105. The prism 80 can be adjusted in the roll, pitch, and yaw directions, which changes the angle at which the ranging beam 43 and visible calibration beam 78 are refracted. This adjusts the azimuth (around the y-axis) and elevation (around the x-axis) angles at which the ranging beam 43 and visible calibration beam 78 exit the detachable range-finding electronics module 1.

In the embodiments discussed above, where the visible calibration laser 39 is integrated into the rangefinder sensor 35, the detachable range-finding electronics module 1 incorporates two or more software modes that allow the user to use the rangefinder sensor 35 to range targets 15 during a shot sequence, or to use the rangefinder sensor 35 to calibrate and align the ranging beam 43 with the line-of-sight 67 on a distant target 15. In the mode where the ranging beam 43 is used to actively calculate the ranged distance 42 of a target 15 during a shot sequence, the transmitter 44 in the rangefinder sensor 35 is enabled and the visible calibration laser 39 is disabled. In the mode where the visible calibration beam 78 is used to calibrate and align the ranging beam 43 with the line-of-sight 67 on a distant target 15, the transmitter 44 in the rangefinder sensor 35 is disabled and the visible calibration laser 39 is enabled.

FIGS. 10A and 10B are plane views of an embodiment of a detachable range-finding electronics module 1 that includes an alignment pin 81 feature. FIG. 1D is a plane view of an embodiment of a fixed-pin archery sight 94 with an alignment slot 82 feature integrated into an embodiment of a vertical adjustment fixture 6. In these embodiments, the alignment pin 81 and alignment slot 82 features mate with each other when the detachable range-finding electronics module 1 is installed on the fixed-pin archery sight 94, and enables the rangefinder sensor 35 to be repetitively aimed accurately with respect to the ranging pin, discussed above, when the detachable range-finding electronics module 1 is installed on the fixed-pin archery sight 94. When mated together, the alignment pin 81 and alignment slot 82 features prevent the detachable range-finding electronics module 1 from moving along the y-axis and pitch (around x-axis) and roll (around z-axis) directions. The features ensure that the detachable range-finding electronics module 1 is attached to the fixed-pin archery sight 94 in the same orientation each time it is installed on the fixed-pin archery sight 94.

FIG. 19 is a schematic illustration of a complex embodiment of an electronics package included in the detachable range-finding electronics module 1. In addition to the electronics incorporated in the embodiment shown in FIG. 18 and discussed above, this embodiment of an electronics package integrates memory 56, one or more displays 25, display and parameter inputs 58, an illuminating element luminosity calibrator 59, one or more cameras 60, and an radio-frequency identification (RFID) scanner 101.

In one embodiment of the memory 56 integrated into the complex electronics package of the detachable range-finding electronics module 1, the memory 56 stores variable data that can be altered. For example, the target distance each aiming pin 8 is calibrated to. This allows the distance associated with each aiming pin 8 to be changed, unlike the more basic embodiments of the detachable range-finding electronics module 1 discussed above. When the aiming pin 8 distances are updated, the processor 34 uses the updated target distance variables to determine which illuminating element(s) 27 to illuminate when receiving data from the rangefinder sensor 35 during the ranging process of an archery shot. This embodiment of memory 56 is non-volatile. In another embodiment, the non-volatile memory 56 stores video or image data collected from an integrated camera 60.

In another embodiment, volatile memory 56 is integrated into the detachable range-finding electronics module 1 to store temporary data. In this embodiment, the volatile memory 56 stores data, such as GPS sensor 38 latitude and longitude data and illuminating element luminosity calibrator 59 variable data. This data can change over time while using the detachable range-finding electronics module 1 and become obsolete. The use of volatile memory 56 allows this temporary obsolete data to be cleared.

FIG. 5 is a plane view of a detachable range-finding electronics module that integrates a rear facing display 25, in an embodiment. The display 25 integrated into this complex embodiment of the detachable range-finding electronics module 1 provides information to the user during an archery shot sequence. As discussed above, one embodiment of the display 25 provides a battery level indicator 41, cant indicator 23, and level indicator 22. This embodiment can also display the actual distance 40 to the target 15. This embodiment of the display 25 is oriented on the back face of the detachable range-finding electronics module 1, adjacent to the aiming pins 8.

FIG. 20 is a plane view of another embodiment of a detachable range-finding electronics module 1 that includes a display 25, which is used to display a graphical user interface (GUI) 61. This embodiment displays menus and statuses to view and change variables associated with the detachable range-finding electronics module 1. FIG. 20 illustrates just some of the menus and variables that the display 25 can provide. This embodiment of a display 25 can be integrated into the same embodiment as previously discussed, shown in FIG. 5.

As shown in FIG. 20, the display and parameter inputs 58 allow the user to interact with, and move through, the GUI's 61 menus, and adjust variables associated with the detachable range-finding electronics module 1. In an embodiment, the display and parameter inputs 58 consist of a multitude of buttons and are oriented adjacent to the display 25. In another embodiment of the display 25 and display and parameter inputs 58, the two are combined into a touch-screen display 25.

In another embodiment, the detachable range-finding electronics module 1 makes use of a wireless communications module 52 for the display and parameter inputs 58. In this embodiment, the detachable range-finding electronics module 1 communicates with a mobile device 62, such as a cellular phone. FIG. 21 is a schematic illustration of an embodiment of a mobile device 62 used for the display and parameter inputs 58. The mobile device 62 has an application installed that provides a GUI 61. The GUI 61 displays menus that allow variables associated with the detachable range-finding electronics module 1 to be viewed and changed. In this embodiment, the display and parameter inputs 58 can be buttons or a touchscreen. When updating parameters, the mobile device 62 pushes the updates to the detachable range-finding electronics module 1 through wireless communication technology, such as IR, Bluetooth®, or WiFi.

As shown in FIGS. 12A and 12B, the illuminating element luminosity calibrator 59 adjusts the luminosity of the illuminating elements 27, in an embodiment. In this embodiment, the illuminating element luminosity calibrator 59 implements a potentiometer 63, and is adjusted manually.

FIG. 22A is a top perspective view of a detachable range-finding electronics module 1 that illustrates an embodiment of an illuminating element luminosity calibrator 59 that implements a phototransistor 64. In this embodiment, no user input is necessary. The phototransistor 64 automatically measures the luminosity of the ambient light, allowing the processor 34 to adjust the luminosity of the illuminating elements 27 accordingly.

FIG. 22B is a top perspective view of a detachable range-finding electronics module 1 that illustrate an additional embodiment of an illuminating element luminosity calibrator 59 that implements a photodiode 65. In this embodiment, no user input is necessary.

During the ranging process of an archery shot, one of the aiming pins 8 is used as the ranging pin to aim the ranging beam 43 of the rangefinder sensor 35. As shown in FIG. 24B, the ranging beam 43 is oriented so that it intersects the line-of-sight 67 at the target 15. As sown in FIG. 23, the line-of-sight 67 is the invisible line made by the user aligning their eye 33 with the peep sight 66, aiming pin 8 used for ranging, and the target 15. FIG. 23 is an illustration that depicts the line-of-sight 67. In one embodiment, the top aiming pin 8 is used as the ranging pin. In another embodiment, the aiming pin 8 that is used for ranging can be selected and changed through the use of a display 25 and display and parameter inputs 58. This embodiment also requires the use of non-volatile memory 56 to store the ranging pin variable data.

As shown in FIGS. 27A-27D, the connect/disconnect system 95 allows the detachable range-finding electronics module 1 to be installed and removed from the fixed-pin archery sight 94, in an embodiment. The connect/disconnect system 95 also generates a seal with the illuminating element gasket 57 around the fiber optic repositories 12 while the detachable range-finding electronics module 1 is installed. In this embodiment, the connect/disconnect system 95 is comprised of a slot 83, catch hook 84, hinge 85, snap-fit hinges 86, snap lock 87, and latch assembly 88.

FIG. 27A is a plane view of an embodiment of a fixed-pin archery sight 94 that illustrates an embodiment of the slot 83 and catch hook 84 features of the connect/disconnect system 95. In this embodiment, the slot 83 feature is integrated into the vertical adjustment fixture 6 of the fixed-pin archery sight 94 and receives the hinge 85 feature of the detachable range-finding electronics module 1. Once the hinge 85 feature is slid into the slot 83 feature, the slot 83 allows the hinge 85 to rotate in the roll (around x-axis) direction. In this embodiment, the catch hook 84 feature is integrated into the aiming pin housing 7 and enables the latch hook 91 feature of the latch assembly 88 to engage the fixed-pin archery sight 94. This aids in generating a downward force on the detachable range-finding electronics module 1, creating a seal with the illuminating element gasket 57.

FIGS. 27B and 27D are plane views of an embodiment of a detachable range-finding electronics module 1 that illustrates the hinge 85, snap-fit hinge 86, and snap lock 87 features of the connect/disconnect system 95. The hinge 85 feature allows the detachable range-finding electronics module 1 to rotate about the fixed-pin archery sight 94. This feature also aids in temporarily securing the detachable range-finding electronics module 1 to the fixed-pin archery sight 94, preventing the detachable range-finding electronics module 1 from rotating in the pitch (around x-axis) and yaw (around y-axis) directions, fixing it in the x- and y axes.

In the embodiment shown in FIGS. 27B and 27D, the snap-fit hinges 86 allow the latch assembly 88 to be secured to the detachable range-finding electronics module 1. Cylindrical features in the latch assembly 88 mate with the snap-fit hinges 86, and allow the latch assembly 88 to rotate while secured to the detachable range-finding electronics module 1. The snap lock 87 feature mates with the latch lock 93 feature of the latch assembly 88 when the latch assembly 88 is secured to the detachable range-finding electronics module 1 and the latch assembly 88 is engaging the catch hook 84 feature of the fixed-pin archery sight 94. The mating of the snap lock 87 and latch lock 93 features prevents the latch assembly 88 from rotating while the latch assembly 88 is securing the detachable range-finding electronics module 1 to the fixed-pin archery sight 94.

As shown in FIGS. 29A-29C, the latch assembly 88 is the feature of the connect/disconnect system 95 that generates a downward force on the detachable range-finding electronics module 1, allowing the illuminating element gasket 57 to create a seal around the fiber optic repositories 12, in an embodiment. In this embodiment, the latch assembly 88 also aids in temporarily securing the detachable range-finding electronics module 1 to the fixed-pin archery sight 94, fixing the detachable range-finding electronics module 1 in the z-axis and preventing it from rotating in the roll (around z-axis) direction. The latch assembly 88 is comprised of a slide button 89, rod 90, latch hook 91, compression spring 92, and latch lock 93. The slide button 89 is a feature that allows the compression spring 92 to be compressed, which releases the mating of the latch lock 93 feature of the latch assembly 88 from the snap lock 87 feature of the aiming pin housing 7. The rod 90 feature secures the two main bodies of the latch assembly 88 to each other, acts as a hinge, and secures the compression spring 92 in place. The latch hook 91 feature allows the latch assembly 88 to be connected and secured to the fixed-pin archery sight 94 when it is mated with the catch hook 84 feature of the aiming pin housing 7. The compression spring 92 generates a force on the latch lock 93 that keeps the latch lock 93 feature mated with the snap lock 87 feature when the detachable range-finding electronics module 1 is installed on the fixed-pin archery sight 94. When the compression spring 92 is compressed by the slide button 89 feature, the latch lock 93 feature becomes unmated from the snap lock 87 feature, allowing the latch assembly 88 to rotate away from the detachable range-finding electronics module 1. During this rotation, the latch hook 91 feature becomes unmated from the catch hook 84 feature, which removes the latch assembly 88 from the fixed-pin archery sight 94. This allows the detachable range-finding electronics module 1 to be removed from the fixed-pin archery sight 94. The latch lock 93 feature mates with the snap lock 87 feature of the aiming pin housing 7 and allows the latch assembly 88 to be locked in place while the detachable range-finding electronics module 1 is installed on the fixed-pin archery sight 94.

As shown in FIGS. 30A, 30B, 31A, and 31B, a magnetic connect/disconnect system 106 comprises of a multitude of magnets 107, in an embodiment. In this embodiment, the magnets 107 are installed on the mating faces of the fixed-pin archery sight 94 and/or detachable range-finding electronics module 1. The magnets 107 are the mechanism that provides a downward force on the detachable range-finding electronics module 1 onto the fixed-pin archery sight 94, creating a seal with the illuminating element gasket 57 around the fiber optic repositories 12. The attractive force of the magnets 107 is also the mechanism that secures the detachable range-finding electronics module 1 to the fixed-pin archery sight 94 when installed, preventing the detachable range-finding electronics module 1 from moving and rotating in all axes and directions. Magnetic material or polar opposite magnets 107 are used on the opposite mating surfaces of the magnets 107, allowing the magnets 107 to attract and become secured to the opposite surface.
