摘要： A linear encoder may be used to accurately determine a number of cartridges within a magazine. Further, using a set of magnetic sensors within a buffer tube of a firearm, it is possible to determine whether a cartridge is loaded within a chamber of the weapon and/or whether the firearm is jammed. The determination of cartridges within the magazine in conjunction with the determination of whether a cartridge is in a chamber of a firearm can give a user an accurate ammunition count. Further, the use of the linear encoder makes it possible to accurately determine the cartridge count when different cartridges are loaded into the magazine or when the magazine degrades in quality over time. Moreover, the ability for magazines to communicate with a firearm enables a user to determine a total available ammunition to the user in a single display without individually checking each magazine.

摘要： The subject matter described herein includes methods, systems, and computer program products for determining an ammunition round count by resistive encoding. According to one embodiment, a system for providing an indication of a number of rounds of ammunition in a magazine of a firearm includes a follower for the rounds to rest upon, where the follower is internal to the magazine and pushes the follower and the rounds toward a mouth of the magazine to facilitate feeding the rounds into the firearm. The system also includes a resistive strip membrane potentiometer sensor arranged substantially along a length of the magazine that generates an output voltage when a first and a second circuit are connected by applying pressure to a surface of the sensor. The output voltage varies based on a position where the pressure is applied to the surface of the sensor and the first and second circuits are connected. A power source, such as a battery or AC/DC adapter, applies power to the system which contains a constant current source to generate and provide an input voltage to the resistive strip membrane potentiometer sensor. A wiper applies pressure to the surface of the sensor and connects the first and second circuits. The wiper is a non-conductive mechanism attached to the follower and configured to move along the length of the magazine corresponding to the resistive strip membrane potentiometer sensor. A round counter converts the output voltage generated by the resistive strip membrane potentiometer sensor into an indication of the number of rounds of ammunition in the firearm magazine (“round count data”).

摘要： A firearm includes a barrel portion, a slide, and a frame. The frame includes a grip, and the grip includes a magazine chamber and a rear surface adjacent the slide. At least one sensor is carried by the grip, and the at least one sensor adapted to sense a state of the magazine detachably received in the magazine chamber corresponding to a number of cartridges of ammunition remaining in the magazine. A display is carried on the rear surface of the grip, and the display includes a plurality of illuminating devices. The display is operatively coupled to the at least one sensor and is operable to visually present the number of cartridges of ammunition remaining in the magazine by illuminating at least one of the plurality of illuminating devices.

摘要： The system includes various components to track and graphically display data related to a user, a weapon, munitions for the weapon, other munitions and equipment used by the user, and similar information about other users. The system can include a display device that can be attached to the weapon. A user can look through the display device while looking down the line-of-sight of the weapon to obtain the data on a heads-up-display. The information displayed can include the point-of-impact of a projectile to be fired from the weapon, the number of unused rounds in the user's inventory, whether a magazine is inserted into the weapon, a map of the field of view, identification of friendlies and hostiles, a distance to a target, a count of other assets (e.g., munitions and other equipment) in the user's inventory, and other information about other users.

摘要： A circuit board that is added to a slide of an semiautomatic handgun for the purpose of counting fired rounds and providing a low ammunition round count signal, as well as a slide lock warning signal, indicating an out of ammunition condition. The circuit board is preferably saddle shaped with downwardly depending wings where warning lights can be located. The board is positioned between front and rear gun sights, below the aiming line of sight, with the saddle shape allowing placement of LEDs that can be seen behind the rear gun sight. In one embodiment, circuitry on the circuit board faces the slide so that the normal underside of the circuit board faces upwardly but below portions of gun sights that establish aiming.
