Abstract
A signal emitting stylus for operation with a digitizer system includes a resonant circuit including a first capacitor and an inductor, the circuit operative to alternate between receiving a wirelessly transmitted first signal and generating electrical field; a controller and a power source. The controller operates the resonant circuit in a receive mode for receiving the first signal, decodes the received first signal and switches operation of the resonant circuit to a transmit mode for generating the electrical field and coupling the electrical field to a digitizer system in response to detecting the first signal. The power source powers generation of the electrical field.
