ABSTRACT:
This invention teaches a novel method of safeguarding and protecting a weapon from being accidentally fired or misused by an unauthorized person. Without a verified pre-registration signal, an arming safety solenoid remains in a fail-safe position, preventing use of the weapon. The electronically actuated solenoid enables the use of trigger only when a valid identification signal is received. The system is comprised of microminiature circuits contained within the grip of the weapon and a ring that is worn on same hand that uses the firearm.
When the weapon is first pickup by the intended user, a switch closure in the grip of the gun turns on a transmitter, which sends a low power, limited range interrogation signal to the finger ring. Upon receipt of this signal, a transponder mounted within the finger ring responds by sending a coded signal that contains a serial number identification. A microprocessor contained within the weapon then compares this decoded signal with one preregistered serial number stored in memory and if the comparison is valid, actuates the arming safety solenoid, allowing the gun to be fired.
Arming the weapon for firing can only be accomplished upon receipt of a verifiable identification signal from the finger ring; the finger ring must be worn by user and be within the range of the electromagnetic transceivers and must be within the range of the magnetic metal sensors.
