Abstract
An authorization system for a firearm includes a personal device worn by the authorized user, modifications to the firearm's fire control system, and an authorization control circuit carried in the backstrap of the firearm handle. The authorization control circuit controls the fire control system and communicates with the personal device. In particular, the authorization control circuit will send a first signal to the personal device via an ultrasonic transponder and wait for a coded response. If the personal device is worn by a user and is within range and properly oriented, it will respond to the first signal. If the correct coded response is not received, the authorization control circuit signals a bi-stable solenoid located near the trigger arm to move its plunger to an extended position where it will cam the edge of the trigger bar out of engagement with the sear when the trigger is pulled. Consequently, the trigger bar will not move the sear. The firearm also forces the user to obtain authorization by not allowing the trigger to be pulled unless the firearm is held in normal firing position grasp. In that position, the user depresses a pressure sensing device on the handle. Depressing that device enables the trigger and initiates the authorization request.
