Abstract

A gun safety system for use with a gun having a barrel, a handle and a safety latch structured for movement from a first disabled position wherein the firing mechanism is inoperable to a second enabled position wherein the firing mechanism operable, comprising a substantially flat main housing attached to the gun handle over the safety latch and having voice and finger print sensing and verification circuitry and means for blocking access to the gun safety latch. The voice and finger print sensing and verification circuitry includes a sensing integrated circuit, having a finger print image surface matrix and a microphone sound sensor, and an authentication integrated circuit electrically interconnected to the sensing integrated circuit, structured to compare the gun user's voice pattern and finger print image to those stored in memory. The means for blocking the safety latch includes a bimetallic strip centrally disposed within a cavity, a capacitor electrically interconnected to a battery, the authentication integrated circuit and the strip, and a substantially flat blocking disk. The blocking disk is sized and shaped to cover access ports in the main housing so that in the absence of user authentication the safety latch is inaccessible. Upon user authentication, the blocking disk moves away from the access ports rendering the safety latch accessible.
