Electromechanical non-numeric control for locks

A light fence represented by aligned apertures in a plurality of wheels permits the passage of a light beam to a sensor to activate an electro-mechanical control for a lock. Such an arrangement avoids the sound-producing mechanical action of the typical tumbler lock and safeguards discovery of the opening combination. Rather than the typical case of a numerical sequencing combination, a novel approach is taken by using visual pattern recognition to align the apertures. The electro-mechanical control of the present invention additionally features optimized energy use, customizable settings, precision positioning, and an expansion of possible combination permutations by including direction of rotation.
