ABSTRACT:
Circuit and method for coupling signals to a tire pressure monitoring system assembled within the interior of a tire in the absence of a receiver are provided. The circuit comprises a coupling circuit that provides capacitance or electromagnetic coupling to pass an externally-derived stream of pulses to a microprocessor therein by either, in the case of capacitance coupling, connecting an external device that generates the stream of externally-derived of pulses to a valve stem of the tire and an electrical ground. In the case of electromagnetic coupling, by placing a suitable external device proximate the coupling circuit. The stream of pulses carries information usable by the microprocessor to perform a respective operational function.
