APPARATUSES AND RELATED METHODS FOR DETECTING COIL ALIGNMENT WITH A WIRELESS POWER RECEIVER
First Claim
1. A wireless power enabled apparatus, comprising:
- a wireless power receiver, including;
a receive coil configured to generate an AC power signal responsive to wireless power transfer from a wireless power transmitter; and
control logic configured to detect misalignment of the receive coil and a transmit coil of the wireless power transmitter responsive to a determination of efficiency of wireless power transfer therebetween.

Abstract
A wireless power receiver may include a receive coil configured to generate an AC power signal responsive to wireless power transfer from a wireless power transmitter, and control logic configured to detect misalignment of the receive coil and a transmit coil of the wireless power transmitter responsive to a determination of efficiency of wireless power transfer therebetween. A method for operating a wireless power receiver may include detecting misalignment between a receive coil and a transmit coil of a wireless power transmitter responsive to detecting monitoring a value indicative of efficiency of wireless power transfer between the wireless power transmitter and the wireless power receiver, and causing an indication to be provided to a user to assist with correcting the misalignment.
