Abstract:
This disclosure provides systems, methods and apparatus for waking a wireless power transmitter from beacon mode. In one aspect a wireless power receiver apparatus is provided. The wireless power receiver apparatus includes a receive circuit comprising a receive coil. This receive circuit is coupled to a load. The receive circuit is configured to wirelessly receive power from a transmitter device at a first power level to power the load. The wireless power receiver apparatus further includes an adjustment circuit configured to be powered by using the wirelessly received power. The adjustment circuit is further configured to adjust a characteristic of the load using the wirelessly received power for a period of time to cause a detectable change in an operating characteristic of the transmitter device for the period of time.
