High speed read/write AVI system

摘要: A transponder (14) for communicating with an interrogator (12) has a high Q-factor resonant circuit (34) of frequency f 1 receiving RF powering signals. The also tuning (56,58) which when in electrical communication the is operable to form lower (60) 3 communications from unit. includes demodulator (66) said (34). Additionally, included control (40) receives demodulated data signal (66). further connected and connect order (60). Control converts signals DC current storing energy. energy stored storage device such as capacitor (46). Other devices, methods systems are disclosed.
