ABSTRACT:
A wireless foot control system includes a receiver and at least one transmitter. The transmitter includes a medium generator for emitting a communication medium, a power supply and at least one foot pedal. The power supply includes a power source, a capacitor bank having a discharge current capacity sufficient to power the medium generator, and a current limiter. The current limiter connects the power source to the capacitor bank, charging the capacitor bank from the power source over a period of time. The foot pedal selectively energizes the medium generator from the capacitor bank. The receiver includes a medium collector for collecting the emitted medium and an electronic circuit. The electronic circuit includes a converter for converting the collected medium to an input control signal and a microprocessor in communication with the converter, the microprocessor having an operating system for generating an output control signal commensurate with the input control signal.
