ABSTRACT:
An electrical circuit for sensing the position of an object with respect to its receptacle. Within the receptacle is mounted a light emitting diode (LED) that generates coded pulses of light. The pulses are sensed by a photodetector mounted on the object. The circuit further includes a clock, gates and a D-flip-flop that together determine whether the photodetector is sensing the coded pulses from the light emitting diode. The light emitting diode and the photodetector are positioned such that the photodetector only senses the coded pulses when the object is located within the receptacle.
