Оптоелектронний годинник

Abstract

An optoelectronic watch comprises a pulse generator, four switches, a correction pulse shaper, five univibrators, two differentiating circuits, a monitoring key, three toggle flip-flops, an OR-circuit, three series circuits consisted of a light-emitting diode and a resistor, an indicator made as a optoelectronic scales of seconds, minutes and hours, each charge being involved a light-emitting diode for time indication, the anodes in the optoelectronic scale of seconds being united and connected to a key output. There is a sensing element, a pulse counter, a decoder, five light-emitting diodes, electric power supply, two optoelectronic NOT-AND circuits, AND-circuit.
