Abstract: Embodiments related to systems, methods, and computer-readable media to enable a power transmit unit (PTU) device are described. In one embodiment a PTU comprises a transmit coil configured for wireless charging via magnetic coupling, a power delivery system coupled to the transmit coil, signal processing circuitry to detect harmonic distortion that is induced in the transmit coil by a device inside the near field of the transmit coil, and control circuitry configured to adjust an output power of the power amplifier when triggered by a detection of an Near Field Communications (NFC) device, a Radio Frequency Identification Device (RFID), or any other such device which may be damaged by the energy emitted from the transmit coil.

Abstract: The disclosure relates to a method, apparatus and system for power transmission unit (PTU) having a sensing unit. The sensing unit may be integrated with the PTU to determine when a power receiving unit (PRU) is proximal and awaken the PTU's charging coil. When a PRU is not present, the PTU may be in Deep Sleep state to save power.

Abstract: A method of wirelessly charging batteries of devices includes detecting at least two devices being simultaneously present on a charging mat. It is determined, for each of the at least two devices, whether the device is compatible with a wireless charging standard. It is determined, for each of the two devices, whether the device is enabled for a near field communication. Charging of the devices is prevented if at least one of the devices is enabled for a near field communication but not compatible with the wireless charging standard.
