  • Patent number: 9960631
    Abstract: A method of monitoring and inductively charging a firearm is implemented with an inductive charging base that includes a chipset, a GPS module, and a wireless communication module. When the firearm is placed onto the inductive charging base, the base charges a portable power source of the firearm and receives a current location of the base from the GPS module. If the firearm is physically separated from the base, then the chipset generates a separation notification. The chipset then sends both the separation notification and the current location of the base with the wireless communication module to contact information stored on the chipset. The contact information is for an authorized user profile of the firearm.

    Abstract: A firearm-magazine interface for replacing an existing firearm-magazine interface of many existing firearms such as assault rifles, namely AK series (AK74, AK47, etc.) provides a lock that holds open the bolt after a last round is fired from a magazine. The firearm-magazine interface also includes a single-button magazine eject. After firing the last round, a bolt-hold lock is urged upwardly in the path of the returning bolt and catches a face of the bolt, thereby locking the bolt open until the magazine is replaced with a replacement magazine, at which time a bolt-hold release paddle pulls the bolt-hold lock downwardly, releasing the bolt to chamber a first round from the replacement magazine.

  • Patent number: 8191297
    Abstract: A device for indicating a limited amount of remaining ammunition in a firearm magazine is disclosed. A switch is mounted within the magazine, to a plate at a bottom end of the magazine. The plate may be a magazine insert, a floor plate, a base plate or a base pad. The switch cooperates with or responds to a segment or portion of a magazine spring. An indicating terminal is coupled with the switch. A change in state of the switch activates and deactivates the indicating terminal. The indicating terminal may be electrically connected to an indicating device. The indicating device may be an LED, an incandescent bulb or a light. The “on” and “off” states of the switch correspond to differing positions of the segment of the spring relative to the switch or to the plate and attendant differing amounts of ammunition in the magazine.

  • Patent number: 8176667
    Abstract: A system for resolving at least one use parameter relating to a firing of a machinegun or of a semi-automatic firearm having a receiver, an action within the receiver and that includes a piston, and a buffer tube that receives at least a portion of the piston during a cycling of the action in response to a recoil. The system includes: a display configured to display at least an indication of at least one use parameter; a sensor disposed in the buffer tube, the sensor sensing a cycling of an action via movement of the piston in the buffer tube; a processor that receives sensed data from the sensor and, based on the received sensed data, calculates the at least one use parameter, the processor causing the display to display the at least an indication; and a power source disposed in the stock or the display and energizing the sensor, the processor, and the display.

  • Patent number: 8109023
    Abstract: A shot counter includes a firearm with a loaded chamber indicator and a striker status indicator. A first switch operates with the loaded chamber indicator and a second switch operates with the striker status indicator. When the loaded chamber indicator moves it activates the first switch and when the striker status indicator moves it activates the second switch. If one of the first and second switches is activated, an electrical signal is sent to a processor and the processor interprets the electrical signal as an indication that a shot has been fired. If the electrical signal is from the first switch, the processor actually counts a number of cartridges going in and out of a chamber of the firearm, and if the electrical signal is from the second switch, the processor actually counts a number of times the firearm was cocked.

  • Publication number: 20110308125
    Abstract: A magazine add-on comprising a platelet arranged to replace the bottom platelet of the magazine and allow measuring the distance, e.g., via an aperture in the platelet, to the magazine's spring-loaded follower either mechanically by an elastic strap, optically by a rangefinder or by measuring the pressure applied by the spring on the platelet. The add-on further displays a number of bullets left in the magazine in a window, either mechanically by numbers on the back of the strap, or electronically on a display attached to the window and connected to the optical or pressure sensor. The add-on is reusable and may be separated and re-attached to various magazines.
