ABSTRACT:
A receptacle counting system includes an ultrasonic sound wave transducer for emitting ultrasonic sound waves and for receiving ultrasonic sound waves reflected from a receptacle whose contact level is to be sensed. There is a rim detector, responsive to the reflected ultrasonic sound waves, for determining the location of the rim of the receptacle and a receptacle detector, responsive to the rim detector, for indicating when a receptacle is present. One or more counters, responsive to the receptacle detector, are provided for monitoring the number of receptacles presented to the system.
