Abstract: An aspect of this disclosure is an apparatus for transmitting power wirelessly. The apparatus comprises a detection circuit and a processor. The apparatus also includes a power amplifier driving an antenna circuit of flexible antenna(s) configured for wireless power transfer. The processor determines that at least one measured variable of the power amplifier falls outside of a corresponding threshold range, indicative of a deformation of a physical shape of one of the flexible antennas or indicative of misalignment of the flexible antennas from a power receiver. The processor further commands the power amplifier to transition to a first power mode from a second power mode based on the determination that at least one of the measured variables falls outside of the corresponding threshold range. The antenna circuit in the first power mode transmits power at a power level less than the power level in the second power mode.

Abstract: The present disclosure describes a power receiving unit for charging while in pre-overvoltage protection. In some aspects, reduced operation of an electronic implant device is initiated before resorting to overvoltage protection. In aspects, the electronic implant device has a power receiving unit capable of receiving power wirelessly from a wireless power transmitter. The power receiving unit can also detect an induced voltage and trigger pre-overvoltage protection when the detected voltage reaches a pre-overvoltage protection threshold. Additionally, a power management integrated circuit (PMIC) of the electronic implant device draws power from the power receiving unit to carry out corresponding functionality. The PMIC also obtains an indication when the detected voltage reaches the pre-overvoltage protection threshold. Based on the indication, the PMIC may reduce the power it draws from the power receiving unit to a predefined, reduced level instead of a normal operating level.
