Abstract
A control system for the remote control of functions on a rotating object from a stationary location is disclosed. The control system, in the disclosed embodiment, constitutes a single channel, four function-select, power transmission system with an encoder at the stationary location and a decoder on the rotating object. The encoder is used to develop selected electrical waveform patterns each of which is uniquely correlated with a particular control function to be performed on the rotating object. Each waveform pattern consists of a unique pattern of electrical waveform half cycles. The particular electrical waveform pattern for the particular control function to be performed is transmitted to the rotating object via center contact assemblies which engage opposite ends of a spindle on which the rotating object is supported for rotation. The decoder circuit detects the particular electrical waveform pattern which is received on the rotating object and causes the electrical power of that waveform pattern to be used to perform the particular control function. The disclosed application of the invention is in an unbalance compensator.
