Abstract
An apparatus for monitoring and controlling the level of ice in an ice storage container includes an emitter mounted within the ice storage container and a detector mounted directly opposite from the emitter. A pulse circuit drives the emitter such that it outputs a pulse train that triggers the detector. A receiver circuit outputs a signal responsive to the detection of the pulse train by the detector. A controller activates an ice maker responsive to the output of the receiver circuit.
