First Claim
Patent Images
1. A hybrid charging method for wireless transmission of power to a portable electronic device, comprising:
- connecting a hybrid receiver to an internal power source and a backup battery;
receiving pockets of energy comprised of power RF signals at receiver antenna elements to produce an AC voltage from a RF circuit connected to a transmitter;
rectifying the AC voltage to a direct current voltage;
converting the direct current voltage to a constant direct current voltage output; and
;
providing the constant direct current voltage output to power either or both the backup battery and the internal power source of the hybrid receiver.
