WIRELESS POWER TRANSFER PROTECTION
First Claim
1. A method for wireless power transfer, the method comprising:
- operating a wireless power receiver in a default protection state in which charging or powering of a load coupled to the wireless power receiver is inhibited except upon detection of one or more safety charging conditions for safely charging the wireless power receiver;
determining that a safety charging condition, of the one or more safety charging conditions, is met; and
operating the wireless power receiver in a charging state at least in part in response to determining that the safety charging condition, of the one or more safety conditions, is met, the wireless power receiver powering or charging the load while in the charging state and receiving power.

17. A wireless power receiver comprising:
-
a detection circuit configured to determine that a safety charging condition is met and to produce a charge control signal in response to determining that the safety charging condition is met; and a charging circuit, communicatively coupled to the detection circuit and to a load, and configured to power or charge the load using wirelessly transferred power, the charging circuit configured to operate in a charging state in response to receiving the charge control signal, and in the absence of receiving the charge control signal to operate in a default protection state in which powering or charging of the load is inhibited. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

30. A non-transitory computer readable media programmed with instructions, executable on a processor, to:
-
operate a wireless power receiver in a default protection state in which charging or powering of a load coupled to the wireless power receiver is inhibited except upon detection of one or more safety charging conditions for safely charging the wireless power receiver; determine that a safety charging condition, of the one or more safety charging conditions, is met; and operate the wireless power receiver in a charging state at least in part in response to determining that the safety charging condition, of the one or more safety conditions, is met, the wireless power receiver powering or charging the load while in the charging state and receiving power.
