Abstract
Abstract A control circuit in which one of a plurality of different frequency input signals is effective to operate one of a plurality of control stations. The input signals, which may be ultrasonic signals, are converted to electrical signals and then to a train of pulses, in which the frequency of the pulse train is related to the frequency of the input signal. The pulses are counted in a dividing circuit in which the divisor is equal to the number of control stations.
