Automatic firearm user identification and safety module

Abstract

An automatic firearm safety system where power consumption is reduced and safety is increased is disclosed. The system includes a movement detector operatively associated with a trigger of a firearm for detecting movement of the trigger. The system also has a transceiver operatively associated with the movement detector for sending a coded signal when movement of the trigger has been detected. The coded signal is received by at least one remote token which receives the coded signal and transmits a coded acknowledgement signal upon receipt of the coded signal. A solenoid is also provided for locking and unlocking the trigger, operatively associated with the transceiver for allowing operation of the trigger and thereby the firing of the firearm when the coded acknowledgement signal has been received by the transceiver. The system may include two tokens, both of which are worn by the authorized user. In this case, the transceiver further includes an anti-collision module to discriminate between the different tokens and select which one will be permitted to issue the coded acknowledgement signal. Also preferably, the transceiver includes an anti-jamming module. Since verification of the token is done every time the trigger is depressed, safety is increased. Furthermore, since bi-directional RF communication is effected only when the trigger is depressed, power consumption is reduced.
