Abstract
Methods and apparatus to detect a cross-connect situation in a wireless power transfer system having one or more power receiving units (PRUs) and one or more power transmitting units (PTUs). The PTU can perturb a transmit coil signal and look for expected correlation on wirelessly connected PRU to determine the presence of absence of a cross-connect condition.
Claims21
A method comprising:
- transmitting first data from a power transmitter unit (PTU), via a first channel, by controlling a transmission parameter to a transmit coil of the PTU;
- receiving at the PTU, via a second channel, second data from a power receiving unit (PRU);
- and
- processing the received second data to determine a level of correlation between the first data and the second data to determine if the PRU is connected to the PTU.

A system, comprising:
- a power transmitter unit (PTU) configured to transmit first data via a first channel by controlling a transmission parameter to a transmit coil of the PTU, and to receive via a second channel second data from a power receiving unit (PRU);
- and
- a processor module configured to process the received second data to determine a level of correlation between the first data and the second data to determine if the PRU is connected to the PTU.
