Abstract

See full text

A control system comprises a liquid crystal display panel; a light source; and a light detector. Light from the source is directed through at least a portion of the liquid crystal display panel to the light detector. A control circuit is provided for holding the liquid crystal display in generally opaque condition while preferably sequentially momentarily clarifying segments of the portion, whereby momentary, sequential, transversely spaced light beams are generated between the light source and the light detector. A timer and logic circuit is provided for correlating signals received from the light detector with generated, individual, spaced light beams that create the signals. Accordingly, occlusion of at least one of the individual light beams with an opaque member causes a specific characteristic response by the timer and logic circuit. In other words, when one of the individual light beams is occluded, the timer and logic circuit emits a characteristic signal which might activate a relay, send an instruction to a microprocessor, or cause some other action.
