Audio controlled gun locking mechanism

Claim 1

In a firearm for discharging a projectile and having a barrel through which the projectile is discharged and a firing mechanism for firing the projectile through the barrel, the firing mechanism including a user operable trigger operable to activate the firing mechanism, and means operatively connected to the trigger for effecting projectile discharge, a safety mechanism for inhibiting operation of the firing mechanism, comprising: blocking means movable into and out of contact with the firing mechanism, said blocking means having a first position inhibiting the firing mechanism from discharging the projectile and a second position at which the firing mechanism is enabled to discharge the projectile; receiving means installed on the firearm for receiving audio frequency signals spoken by the user; and, audio recognition means installed on the firearm and having an input from the receiving means for audio signals received by the receiving means to be directed to the audio recognition means, and said audio recognition means including means for processing received audio frequency signals to determine if a received signal corresponds to a predetermined audio frequency signal to move the blocking means from one position to another, the processing means including a processor in which is stored information corresponding to a predetermined audio input signal spoken by the weapon user, comparing means for comparing a received audio input signal with the stored information to determine if the received signal matches the predetermined audio input signal, means responsive to an output from the comparing means if a match occurs to move the blocking means from one position to the other, and the processing means including means for storing a first predetermined audio frequency signal for comparison with an audio frequency signal spoken by the user when the user wants to fire the weapon and a second predetermined audio frequency signal for comparison with a second audio frequency signal spoken by the user when the user wants to inhibit the weapon from being fired.
