  • Patent number: 11898829
    Abstract: A system includes a guided munition having a housing. A first reservoir is defined within the housing holding a first chemical reactant. A second reservoir is defined within the housing, wherein the second reservoir holds a second chemical reactant configured to undergo an endothermic reaction with the first chemical reactant. A frangible barrier separates between the first and second reservoirs. The frangible barrier is configured to break under forces acting on the guided munition as the guided munition is fired from a weapon. An electronic device can be housed within the housing in thermal contact with at least one of the first reservoir and/or second reservoir for cooling the electronic device with an endothermic reaction upon mixing of the first and second chemical reactants.

  • Patent number: 11852435
    Abstract: 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.

  • Patent number: 11835316
    Abstract: A revolver-type firearm has a barrel-cylinder gap created between its barrel and a rotatable cartridge cylinder. The cartridge cylinder has a plurality of cartridge chambers each with corresponding counterbore retaining a translatable shuttle. When a cartridge is fired, the shuttle expands and translates forward toward the breech-end of the barrel and seals the barrel-cylinder gap to prevent the escape of gases, flames, and residue through the barrel-cylinder gap. When pressure drops as the cartridge projectile exits the barrel, the shuttle contracts. The barrel-cylinder gap opens upon rotation of the cartridge cylinder as the shuttle translates away from the breech-end of the barrel. The shuttle has a thin cylindrical body, a beveled front end, and a conical central bore and is manufactured from a hard elastic metal or metal alloy such as one comprising titanium.
