  • Patent number: 11802747
    Abstract: The invention relates to a firearm analysis device for determining parameters which are indicative for a firearm from a shot which has been discharged from the weapon, as well as a corresponding method, a corresponding firearm and a computer program product. The device comprises a voltage generating unit which generates an alternating voltage (Ue) during a counter-recoil travel and/or recoil travel of a movable weapon part occurring during a firing. The device is characterized by a signal processing unit which generates a measurement signal (IN+) from the generated AC voltage (Ue), a signal evaluation unit which determines a first time point and a second time point during the counter-recoil travel and/or recoil travel of the movable weapon part, and a time determination unit which determines a time period duration between the first time point and the second time point.

  • Patent number: 11435152
    Abstract: The invention relates to a firearm comprising one or more retractable loading system elements, specifically at least one from a loading device, breechblock carrier, or slide. These each follow a trajectory when retracted. The firearm also comprises one or more reference elements, which indicate such a predetermined position of the loading system elements along their respective trajectories, at which the chamber is opened, such that a cartridge potentially located in the chamber can be seen and/or felt, but is not ejected. The predetermined position of the loading system element is distanced to possible positions for disassembling the firearm, and the one or more reference elements are formed such that they ensure that the loading system elements can travel freely along their respective trajectories when the safety for the firearm is either on or off.
