A ballistic detection system includes one or more light sources configured to transmit collimated light through a detection area; a receiver array arranged with respect to the detection area to receive the collimated light in multiple side-by-side channels, the receiver array including (i) light detectors corresponding to the multiple side-by-side channels, and (ii) lenses arranged to focus respective portions of the collimated light, which has transited the detection area, onto respective ones of the light detectors corresponding to the multiple side-by-side channels; and a ballistics analysis computer coupled with the receiver array and programmed to identify a location of a projectile that passes through the detection area by performing ratiometric comparison of signal data from the light detectors, the signal data corresponding to fractional blockage, by the projectile, of the collimated light in one or more of the multiple side-by-side channels.

A firearm system for monitoring the displacement of a firearm trigger during a trigger pull includes a firearm body including a handle and a barrel attached to the handle. A trigger is attached to the firearm body, and a position input circuit is attached to the trigger. The position input circuit emits a trigger position signal including information representative of the trigger displacement. The firearm body is in wired or wireless communication with an electronic device. The electronic device can include a monitor, or screen, for graphically displaying a trigger position indicator representative of the displacement of the trigger along one or more axes. The firearm body can include a motion sensing circuit generally adapted to detect motion of the firearm body. The motion sensing circuit can include one or more accelerometers or gyroscopes. A wireless transmitter or transceiver can be positioned on the firearm body for communicating trigger displacement information and/or firearm body motion information to the electronic device. Methods of providing firearm user input information to a firearm user are also provided.

A method for calculating a position of a dart pin attached to a dart board divided into a plurality of segments in an apparatus for calculating a position of a dart pin is provided. The method includes obtaining a plurality of optical data from a plurality of optical devices corresponding to at least one of a plurality of holes formed in each segment and installed on the rear surface of the dart board; and calculating a position of a dart pin attached to the dart board using the plurality of optical data.

A target system can detect the location of a projectile disposed within a target and subsequently alter an image being displayed on the target in response to the location of the detected projectile. The target system can include a sensor, an image source, a portable electronic device, and a computing device. The sensor can be positioned on the target to detect the location of the projectile on a face of the target. The image source can project an image onto the face of the target. The portable electronic device can receive input from a user to dictate the image(s) displayed on the target. The computing device can be communicatively coupled to the sensor, the image source, and the portable electronic device and cause the target system to detect the location of the projectile and subsequently alter the image displayed on the target in response to the location.

An assembly-type physical dart target includes assembly plates, engagement strips, and a frame. Each assembly plate is formed by an arrow standing layer and a projection layer, and has surface gloss higher than that of the arrow standing layer. The arrow standing layer has two sliding slots disposed on two sides thereof, respectively, and each sliding slot has a retraction side disposed on a side edge thereof away from the projection layer. Each engagement strip has two protruding side edges and an assembly part disposed thereon, and each protruding side edge is engaged with the sliding slot. Therefore, the target can provide a good projection effect, and make image projection technology work well in physical throwing exercise, and has nice structural strength to form a large target, so that a user can quickly assemble the target or partially disassemble the target for replacing a damaged part.

An imaging device captured images of a scene that includes at least one shooter. Each shooter of the at least one shooter operates an associated firearm to discharge one or more projectile. A positioning mechanism positions an infrared filter in and out of a path between the imaging device and the scene. A processing system processes images of the scene when the infrared filter is positioned in the path to detect projectile discharges in response to each shooter of the at least one shooter firing the associated firearm. The processing system processes images of the scene captured when the infrared filter is positioned out of the path to identify, for each detected projectile discharge, a shooter of the at least one shooter that is associated with the detected projectile discharge.

A system has at least one processor, a control subsystem, and an end unit with at least one image sensor. The control subsystem switches operation of the system between first and second modes. In the first mode, an image sensor captures a visible light image of a scene, and a processor analyzes the visible light image to identify a target in the scene and extract target spatial information. In the second mode, an image sensor captures a series of IR images of the scene, and a processor analyzes the IR images to identify firearm projectile strikes on the target based on the extracted spatial information and comparisons between the IR images. In certain embodiments, the same image sensor is used for visible light and IR image, and an IR filter is selectively positioned in an optical path from the scene to the image sensor according to the mode of operation.
