Abstract
An electrical control device having a transducer for producing a plurality of indicating signals proportional to actual components of a force applied to that transducer by an actuator, which actuator has a capacitance relative to electrical ground. The control device further includes a processor for receiving the plurality of indicating signals and producing a plurality of control signals proportional to the indicating signals. The processor communicates the plurality of control signals to a responding device such a computer having a visual display. The control device further includes a circuit connected to the processor and to the actuator of the transducer for monitoring the capacitance of the actuator wth respect to electrical ground. The circuit cooperates with the processor to operate as an oscillator, which oscillator has a frequency proportional to the capacitance of the actuator with respect to electrical ground. The processor is configured to recognize variance of the frequency beyond a specified excursion and to respond to such a variance by generating a plurality of updated reference control signals and communicating those updated signals to the responding device.
