Abstract

A lock and target authentication apparatus for handguns and rifles. The apparatus is designed to fit into handgrips that replace the factory provided handgrips. Flexible membrane circuitry is contained within the handgrips as well as the power source for the apparatus so that the unit does not have to made part of the weapon and can easily be added afterward. The only other modification of the weapon that is necessary is to make a slight change to the trigger assembly or trigger bar. An infra red signal is communicated from a remote transmitter that unlocks a solenoid mechanism that prevents the weapon from being fired. The signal is unique to the weapon. The apparatus also features a target authentication ability so that a number of weapons can communicate with one another to prevent a weapon from being fired at them if that weapon receives a preselectable infra red signal that indicates to the apparatus that the other weapon is a "friend" and not a "foe".

Claims5

Dependent claims

A lock and target authenticating apparatus for a weapon having a trigger that when pulled activates a discharge assembly causing said weapon to discharge, said apparatus comprising:

self-contained, remote transmitter means, located at a distance from said weapon, for emitting a unique signal that corresponds only to said weapon;
sensing means for detecting the signal emitted by said emitter means, wherein said sensing means is attached to said weapon;
locking means, connected to the discharge assembly of said firearm, for preventing the activation of said weapon when said trigger is pulled;
central processing means, connected to said sensing means and said locking means, for evaluating the signal received by said sensing means to verify that is corresponds to only that weapon
internal transmitting means, connected to said central processing means, for sending a unique selectable authentication signal wherein when said authentication signal is detected by a different weapon equipped with said apparatus via its sensing means, said central processing means of said different weapon causes said locking means of said different weapon to lock which cannot be overridden by said self-contained, remote transmitter means corresponding to said different weapon as long as said authentication signal is being detected;
wherein said central processing means causes said locking means to unlock when the signal received by said sensing means is verified.
