METHODS AND APPARATUS FOR WIRELESS CHARGING
First Claim
1. A method to detect eligibility for wireless charging at a power transmitting unit, the method comprising:
- receiving a measured charging pattern from a power receiving unit that is in communication with the power transmitting unit;
when the measured charging pattern does not match a reference charging pattern used to modulate an electrical current at a transmitter resonator of the power transmitting unit, determining that the power receiving unit is not eligible for wireless charging by the power transmitting unit; and
when the measured charging pattern does match the reference charging pattern, determining that the power receiving unit is eligible for wireless charging by the power transmitting unit.

Abstract
A disclosed example method to detect eligibility for wireless charging at a power transmitting unit involves receiving a measured charging pattern from a power receiving unit that is in communication with the power transmitting unit. When the measured charging pattern does not match a reference charging pattern used to modulate an electrical current at a transmitter resonator of the power transmitting unit, the power receiving unit is not eligible for wireless charging by the power transmitting unit. When the measured charging pattern does match the reference charging pattern, the power receiving unit is eligible for wireless charging by the power transmitting unit.

12. A power transmitting unit to detect eligibility of a power receiving unit for wireless charging, the power transmitting unit comprising:
-
a communication interface to receive a measured charging pattern from the power receiving unit that is in communication with the power transmitting unit; and a processor to; determine that the power receiving unit is not eligible for wireless charging by the power transmitting unit when the measured charging pattern does not match a reference charging pattern used to modulate an electrical current at a transmitter resonator of the power transmitting unit; and determine that the power receiving unit is eligible for wireless charging by the power transmitting unit when the measured charging pattern does match the reference charging pattern. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
