    • A broadside small array microphone beamforming apparatus comprises first and second omni-directional microphones, a microphone calibration unit, and a directional microphone forming unit. The first and second omni-directional microphones respectively convert voice from a desired near-end talker into first and second signals. The second and first omni-directional microphones and the desired near-end talker are respectively arranged at three points of a triangle. The microphone calibration unit receives the first and second signals and correspondingly outputs first and second calibration signals. The directional microphone forming unit receives the first and second calibration signals to generate a first directional microphone signal with a bidirectional polar pattern. The adaptive channel decoupling unit receives the first calibration signal and the first directional microphone signal to generate a first main channel signal and a first reference channel signal for noise detection.

    • The present invention is an apparatus and method that regulates the size of an ice bank (50) and that prevents short cycling of the compressor (30) therefor and operation thereof at undesired voltages. A microprocessor based control circuit (10) includes a circuit for sensing line voltage (14) combined with an ice bank sensing circuit (18, 20). The ice bank sensing circuit is of the conductivity sensing type wherein the electrical conductivity between two probes (P1, P2) is sensed. The microprocessor (16) continually monitors the probes (P1, P2) to determine if refrigeration is needed or not, and continually senses the line voltage to determine if that voltage is within the design limits of the refrigeration compressor (30). The voltage sensing circuit (14) can also sense if power has been interrupted where the voltage drops to zero.
