  • Patent number: 10663244
    Abstract: An electromagnetic actuator in one embodiment includes characteristics of very fast actuation, shock invariant design, and compact size. The actuator may be controlled via a small low voltage power source such as a battery and simple switching logic. Such characteristics are ideally suited for incorporating the actuator into the firing mechanism of a firearm, which are subjected to drop tests to confirm the firearm will not discharge in the absence of trigger pull. Very fast snap-like action is attained by balancing the magnetic forces of two opposing permanent magnets around a stationary yoke and rotating member to create three circulating magnetic flux circuits. A central electromagnet coil on the yoke amplifies the magnetic flux of one side of the rotating member or the other depending on the power source actuation polarity, thereby creating two possible snap-like actuation positions. The actuator is usable in firing mechanism release or blocking applications.

    Abstract: The invention is directed toward a heated grip for a firearm. The heated firearm grip comprises a grip body, an electrically resistive heating element, and a power source. The grip body is shaped as a pistol style firearm grip, has a hollow internal cavity, and has a hinged lower lid located on the bottom of the grip body. The power source is located within the hollow internal cavity of the grip body and is electrically connected to the electrically resistive heating element. The grip body is interchangeable with the factory installed grip of a firearm. The electrically resistive heating element may be embedded in a polyurethane sleeve surrounding the external surface of the grip body. The electrically resistive heating element may also be located within the hollow internal cavity of the grip body or molded into the body of the grip body.

  • Publication number: 20150075048
    Abstract: A method and apparatus for intentionally slowing the speed at which detachable ammunition magazines can be interchanged in a firearm receiver. A magazine catch assembly includes a latch adapted to engage a recess of a standard magazine in the magazine well. A hand-activated crank interacts with threads of a push-rod portion of the latch so that manual rotation of the hand crank in one direction (e.g., counter-clockwise) displaces the latch after a sufficient number of turns. Reverse rotation of the hand crank returns the latch to its engaged condition ready to automatically re-engage the next magazine inserted into the firearm receiver. Alternatively, viscoelastic foam or other mechanical time-delay feature can be used instead of screw threads to introduce a mechanically transmitted dwell period before the latch is actuated.

  • Patent number: 8931195
    Abstract: A gun locking and unlocking device, which may be configured to be disposed adjacent the trigger of a gun to alternatively prevent or enable firing, includes a data receiver, a data memory and a logic device for determining whether data received by the receiver is the same, or substantially the same, as data stored in the data memory. One or more separate electronic gun keys are provided to transmit gun lock/unlock data to the data receiver of the gun lock device. The logic device responds to a gun control signal transmitted by one of the gun key devices with priority over a gun control signal transmitted by another gun key device. The logic device automatically locks the gun when it is located in a prohibited area, such as a school. The logic device also locks the gun when the gun user is intoxicated or acting in an irrational manner. Once locked, the user must set a timer which allows the gun to be unlocked only after a specified “wait” time.

  • Publication number: 20140360077
    Abstract: A tactical rail incorporating integral conductive elements positioned in rail channels or grooves wherein the conductive elements are powered by a single battery. Accessory mounts incorporate conductive elements positioned to contact the conductive elements in the rail grooves thus receiving electric current from the conductive elements and delivering the same to the connected accessories. A rubber O-ring strip or gasket may be removably positioned over the conductive elements positioned in the rail grooves thereby preventing the system from shorting out and protecting the conductive elements from external conditions, including moisture. When needed, portions of the O-ring strip may be cut-away to accommodate the conductive elements of one or more accessory mounts.

    Abstract: A method and apparatus for intentionally slowing the speed at which detachable ammunition magazines can be interchanged in a firearm receiver. A magazine catch assembly includes a latch adapted to engage a recess of a standard magazine in the magazine well. An input pad receives an input signal from a user that initiates a count-down sequence. When the count-down sequence is finished, an actuator mechanism is displaces the latch to disengage the magazine for replacement. Return of the latch to the engaged position may be automatic or user-initiated. The count-down sequence may be electronic or manual. User input may require use of a specialized tool. The latch may be spring-biased toward the engaged condition. The input pad may be responsive to an authoritative wireless over-ride signal to remotely disable the firearm.
