CPC H02J 50/23 (2016.02) [H02J 50/80 (2016.02); H02J 50/90 (2016.02); H02J 50/10 (2016.02)] | 20 Claims |
1. A wireless 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;
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, a power level of the AC wireless signals, or combinations thereof; and
a transmitter integrated circuit including:
a demodulation circuit including a slope detector circuit and a high pass filter circuit, the high pass filter circuit configured to variably alter a resistance of the high pass filter circuit based on the electrical information, the demodulation circuit configured to (i) receive the electrical information from the at least one sensor, (ii) detect a change in the electrical information, (iii) determine if the change in the electrical information meets or exceeds one of a rise threshold or a fall threshold, (iv) if the change exceeds one of the rise threshold or the fall threshold, generate an alert, and (v) 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.
