Magazine Shot Patents (Class 42/1.02)
  • Patent number: 10900727
    Abstract: 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.

    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.

  • Publication number: 20140250750
    Abstract: A magazine is disclosed including a storage tube and a biasing member positioned within the storage tube. A strip engages the follower and extends toward a distal end of the storage tube. A display member is coupled to the strip and is viewable through the storage tube. The display member displays a state of the strip. The strip may be coupled to the follower and wrap around an axle or spool engaging an axle. The display member may be a window such that a portion of the strip around the axle is viewable. The strip may include visual indicators that are visible through the window and indicate a number of rounds within the magazine. A switch may be selectively activated to illuminate a portion of the strip viewable through the window.

  • Publication number: 20140202056
    Abstract: An apparatus known as a self-illuminating light-emitting firearm magazine indicator, or simply, light-emitting magazine indicator, (LEMI), is described here forth. The light-emitting firearm magazine indicator makes use of a self-illuminating device. The device and/or materials could comprise: radioactive gaseous isotopes, self-illuminating paint or any other substance that contains self-luminous properties. The light-emitting firearm magazine indicator will make use of any form of self-illumination technology that require no external power source or battery technology in order to give off light emissions. The light-emitting firearm magazine indicator will use the properties of radio-luminescence as a primary, but not exclusive source to create such attributes.

  • Patent number: 8733007
    Abstract: A magazine assembly (10) for receiving and storing cartridges (28) for a firearm (1). At least one gate member (58, 60) is pivotally mounted at an open end of a monoblock (20) and has a first blocking member (58.1, 60.1) to inhibit feeding of an end cartridge from a feed port until the firearm (1) is cocked. The gate member (58, 60) further includes a second blocking member (58.4, 60.4) to prevent multiple cartridges (28) from feeding from the same feed port (20.3, 20.4) during a given cocking cycle. The gate member (58, 60) is operable to displace the first blocking member (58.1, 60.1) out of a cartridge feed path while placing a second blocking member (58.4, 60.4) in the feed path to of the next cartridge (28) to be fed. An interrupter (62) prevents cartridges (28) supplied by a plurality of feed ports (20.3, 20.4) from being fed simultaneously.

  • Publication number: 20140109451
    Abstract: The present invention involves techniques for rapid, flexible, partial and supplemental reloading of firearms using specialized actions, intermediate storage devices/feeds and multiple magazines, which may, in some embodiments, be simultaneously engaged with a firearm. The techniques disclosed include a feeding system, which may be a multiple-magazine feeding system, that allows a firearm to remain loaded and firing-ready with multiple loaded cartridges at all times, even during reloading operations. The invention also includes other techniques for flexible, non-wasteful, partially-empty reloading, to eliminate reloading paralysis, and allow the soldier or other user, not the size of a magazine, to determine when firing should continue and when and if it should pause.

  • Patent number: 8601733
    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.

  • Patent number: 8572875
    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.
