Claim 16:
17. A wireless power transmission system comprising:
a transmitter antenna configured to couple with at least one other antenna of at least one other system and transmit alternating current (AC) wireless signals to the at least one other antenna, the AC wireless signals including wireless power signals and wireless data signals, the wireless data signals generated by altering electrical characteristics of the AC wireless signals at the at least one other system, the transmitter antenna including a source coil and an internal repeater coil;
at least one sensor configured to detect electrical information associated with the electrical characteristics of the AC wireless signals, the electrical information including one or more of a current of the AC wireless signals, a voltage of the AC wireless signals and a power level of the AC wireless signals;
a demodulation circuit configured to (i) receive the electrical information from the at least one sensor, (ii) apply automatic bias control and gain control to the electrical information to generate a modified electrical information signal (iii) detect a change in the modified electrical information signal, (iv) determine if the change in the modified electrical information signal meets or exceeds one of a rise threshold or a fall threshold, (v) if the change exceeds one of the rise threshold or the fall threshold, generate an alert, (vi) and output a plurality of data alerts; and
a transmitter controller configured to (i) receive the plurality of data alerts from the demodulation circuit, and (ii) decode the plurality of data alerts into the wireless data signals.
