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.

Detecting objects placed on wireless charger

A sensor system can include a sensor coil and a sensor coupled to the sensor coil. The sensor coil can include coil portions that generate signals based on magnetic coupling induced in the coil portions by a receiving coil device (e.g., a NFC tag) and magnetic distortion induced in the coil portions by magnetic coupling of a power transmitting unit (PTU). The sensor can reduce the magnetic distortion induced in the first and the second coil portions by the PTU, detect the receiving coil device based the first and the second signals, and control the PTU based on the detected receiving coil device.

Sensing coil system

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.

Method and apparatus for PTU detection of NFC devices

Techniques related to wireless communication of an input device are described herein. An apparatus may include a display at the input device, a wireless transmission architecture, and a wireless receiver. The wireless transmission architecture is to broadcast a signal to the display, and wireless receiver to receive the broadcast signal at the display. The broadcast signal is configured to provide a power signal to initiate operations of the display, a data signal to provide content to be displayed at the display, or any combination thereof.

Wireless energy and data transfer to a display of an input device

A wireless power transfer device and method including a first coil of wire having a first winding to receive electrical current and emit a first electromagnetic field, a second coil of wire having a second winding to receive electrical current and emit a second electromagnetic field, the second electromagnetic field weaker than the first electromagnetic field. A combined electromagnetic field of the first electromagnetic field and the second electromagnetic field to transmit power wirelessly through a first external surface of the wireless power transfer device to a receiving device, and decay faster over distance through a second external surface of the wireless power transfer device than through the first external surface.

Multiple coils for wireless power

This disclosure describes systems, methods, and apparatus related to near field communication (NFC) detection. A device may determine a first device in proximity to a charging area of the device. The device may detect a presence of a first NFC device in proximity to the charging area of the device. The device may determine the first NFC device is associated with the first device. The device may determine to transition the device to one or more operating modes based at least in part on the presence of the first NFC device.
