The invention relates to a device for detecting and counting live bullet shots, blank shots and dry-firing actuation of the striker for all types of semi-automatic or automatic weapons, said device being able to discriminate between said three events and comprising: an electronic circuit; a first sensor for detecting a movement of a part of the weapon preceding a potential live bullet shot or blank shot; and a second sensor for measuring recoil acceleration when the live bullet shot or blank shot has been fired.

Device for counting live shots, blank shots and dry shots

The invention relates to a device for detecting and counting live bullet shots, blank shots and dry-firing actuation of the striker for all types of semi-automatic or automatic weapons, said device being able to discriminate between said three events and comprising: an electronic circuit (); a first sensor for detecting a movement of a part () of the weapon preceding a potential live bullet shot or blank shot; and a second sensor () for measuring recoil acceleration when the live bullet shot or blank shot has been fired.

Improved sighting system for a fire arm, characterised in that it comprises a single indicator light (); a sighting device () providing an alignment opening () with a longitudinal reference plane (XoX') which is parallel or mainly parallel to the axis (Y-Y&#x2032;) of the barrel () and which is aligned with the indicator light (); an inclinometer to measure the elevation angle (A) of the fire arm (); a ballistic calculator () connected to the indicator light () and to the inclinometer, making it possible to calculate the desired angle of inclination of the fire arm () as a function of the distance of the target () and to control the indicator light () so as to signal at what moment the measured elevation angle (A) corresponds to the calculated elevation angle.

Sighting system for a fire arm

An authorization system for a firearm () includes an authorizing device () worn by the authorized user, and a firearm () with a fire control system, a computer controller (), and a piezo-electric disabler (). The computer controller () communicates with the authorizing device (), and if no authorizing signal is received from the authorizing device, sends an electric output signal to the disabler () to prevent the fire control system from allowing the firearm to fire. The disabler, upon application of the electrical signal from the computer controller, cams the rearward moving trigger bar () of the fire control system clear of the hammer link () to disrupt the fire control system. Consequently, the firearm () will not fire.

Firearm authorization system with piezo-electric disabler

The invention concerns a fire arm equipped with an enabling system which comprises a transmitter/receiver (,) of ultrasonic waves mounted on the fire arm, a unit (,) to be carried by the shooter, containing means (,) for sending back a signal transmitted to the latter by said transmitter/receiver (,) and a monitoring device (,) monitoring the signal received by the above-mentioned receiving part, controlling a device (,) which can prevent any firing. The enabling system contains a timer (,) which can measure the length of time between the transmission of a signal by the transmitter/receiver (,) and its reception by the latter, and a device (,) to calculate the distance covered by said signal, whereby the monitoring device (,) only makes it possible to fire when it recognizes the signal and when on top of that the above-mentioned distance is inferior to a certain limit.
