ABSTRACT:
There is disclosed an automated flush system which senses the approach and departure of an object or person and produces control signals indicative of said approach and departure, respectively. A discriminator unit receives and decodes the approach and departure signals to produce a flush control signal which controls a flush valve in the flush system as a result of the occurrence of the departure signal following the occurrence of the approach signal.
