Audio controlled gun locking mechanism
First 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.

Abstract
A firearm (W) is for discharging a projectile such as bullet (B) through a barrel (L). The firearm includes a firing mechanism (F) for firing the bullet through the barrel. The firing mechanism includes a trigger (T) which is operable by the person using the firearm to fire the weapon. A firing pin (P) is operatively connected to the trigger for contacting a cartridge (C) and effecting discharge of the bullet. A safety mechanism (10) is provided to inhibit operation of the firing mechanism. The safety mechanism includes a blocking element (28) movable into and out of contact with the firing mechanism. The blocking element has 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. An audio receiver (14) is mounted on the firearm for receiving audio frequency signals such as a word or words spoken by the person using the firearm. An audio recognition unit (18) also mounted on the firearm has an input from the receiver. Received audio signals are directed to the audio recognition unit which includes a processor for processing the received audio frequency signal. If the received signal corresponds to a predetermined audio frequency signal, the blocking element is moved from its inhibiting position to its enabling position.
