  • METHODS AND APPARATUS FOR WIRELESS CHARGING
    Publication number: 20170093175
    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.
