Abstract

A firearm, such as a shotgun, is normally-enabled at all times for firing. An authorized user, such as a police officer, wears a transmitter that transmits signal energy in all directions. The transmitter may be worn by the authorized user on the user's person. The transmitter transmits a "disable" system that is received by a corresponding signal receiver built into the firearm only when the muzzle of the firearm is pointed in the direction of the authorized user. That is, the receiver has a narrow angular spatial range of signal reception. In this way, if the firearm is taken away from the authorized user, or the authorized user accidentally points the firearm at his/her person, then the firearm will be disabled automatically from firing by reception of the "disable" signal sent by the transmitter worn by the authorized user.
