SPREAD SPECTRUM WIRELESS RESONANT POWER DELIVERY
First Claim
1. A spread spectrum power delivery system for wirelessly delivering electric power to a target device, the spread spectrum power delivery system comprising:
- a spread spectrum power source comprising;
a power source operable to source spread spectrum alternating current power;
a sending resonant coupling component operable to couple the spread spectrum alternating current power to a transmitting element for wireless power transmission by a non-radiated magnetic field;
the spread spectrum power source capable of dynamically tuning the wireless power transmission according to a spread spectrum sequence; and
a communication module coupled to the spread spectrum power source and operable to communicate the spread spectrum sequence to the target device.

Abstract
Wirelessly delivering electric power to a target device. Operation includes generating a spread spectrum sequence, generating spread spectrum alternating current power based upon the spread spectrum sequence, coupling the spread spectrum alternating current power to a transmitting element for wireless power transmission by a non-radiated magnetic field, dynamically tuning the wireless power transmission according to the spread spectrum sequence, and communicating the spread spectrum sequence to the target device. The spread spectrum sequence may include a frequency hopping sequence and/or a phase hopping sequence. Communicating the spread spectrum sequence to the target device may employ Radio Frequency (RF) communications and be used to exchange a target device identity, target device billing information, target device power receipt level(s), a target device battery charge state, a request for power delivery from the target device, and/or authentication information from the target device.
