Electronic transponder tuning circuitry

摘要: A method is disclosed herein for tuning a responder unit (12). The comprises the stops of storing energy in accumulator (136) contactless fashion by RF transmitted from interrogator (10) to (12), and exciting within (12) an carrier wave. further transmitting wave first response measuring received signal strength response. In accordance with invention data may be sending at least one programming sequence upon receiving would preferably modify internally stored frequency setting memory (244) set data. Other devices, systems methods are also disclosed.
