Patent ID: 7822694

Claim:
A control system comprising: a plurality of control circuits, each control circuit comprising the following elements: an input receiving connection for receiving an input signal; an oscillation generation circuit for generating at a first output terminal an oscillation output signal having an amplitude, phase and a frequency; a first spike generation circuit in communication with the oscillation generation circuit for generating a first spike signal when the oscillation output signal crosses a first threshold value, the first spike signal being provided at the first output terminal; a second spike generation circuit in communication with the oscillation generation circuit for generating a second spike signal when the oscillation output signal crosses a second threshold value, the second spike signal being provided at the first output terminal; wherein the oscillation output signal, the first spike signal and the second spike signal collectively form a composite output signal which is capable of controlling an actuating element, and wherein characteristic information of the actuating element is provided as part of the input signal to the control circuit to thereby adjust one of the amplitude, phase and frequency of the oscillation output signal.
