Abstract
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.
Claims10
A method for identifying firing events of a weapon, the firing events including live bullet shots, blank shots, and dry-firing actuations of a striker of the weapon, the method comprising:
- detecting and analyzing a movement of a part of the weapon prior to a potential live bullet shot or blank shot, and
- measuring a recoil acceleration of the weapon when the potential live bullet shot or blank shot has taken place, and
- detecting and discriminating between the firing events including:
- detecting a firing event as a dry-firing actuation of the striker when the part of the weapon is displaced in a single direction,
- detecting the firing event as a live bullet shot or a blank shot when the part of the weapon is displaced successively in two opposite directions,
- detecting the firing event as a blank shot when the recoil acceleration comprises two components of opposite directions, and
- detecting the firing event as a live bullet shot when the recoil acceleration comprises one component in a single direction.
