Apparatus and method for actuating a weapon accessory by a laser sighting beam

摘要

A system for actuating an accessory mounted on a weapon with the sighting light beam generated by a laser sighting device. A light probe, adapted to be mounted on the weapon proximate the optical pathway of a sighting beam of light generated by a laser sighting device, is provided for detecting the sighting beam and producing in response thereto an electrical detection signal. An actuation circuit, adapted to be mounted on the weapon, is provided for receiving the detection signal and, in response thereto, actuating an electrical accessory mounted on the weapon. An ambient light sensor is provided for receiving ambient light and producing an electrical reference signal. The actuation circuit includes a comparator for comparing the detection signal to the ambient light signal and actuating a flashlight or other accessory when the detection signal passes the reference signal by a predetermined amount. The system inhibits the accessory when the ambient light passes a predetermined intensity.
