A docking station apparatus and method provides wireless power and wireless communications to a mobile device, and provides or establishes connections to one or more external devices such as monitors, keyboards, mice, printers, and networks. In response to detection of the presence of the mobile device, the docking station is enabled to transfer wireless power to the mobile device and communicate wirelessly with the mobile device. The docking station also provides or establishes connections to external devices in response to one or more connectivity assignments.

This disclosure describes methods, apparatus, and systems related to a maximum coil current system. A device may determine a presence of a first device placed on a charging area of the device, the charging area including a power transmitting surface. The device may establish a connection with the first device using one or more communication protocol. The device may identify device information associated with the first device using the established connection. The device may determine a maximum charging current for the first device based at least in part on the device information.

Device dependent maximum coil current

This disclosure is directed to power delivery including out-of-band communication. In general, a device to be charged and a charging device may interact using two separate wireless signals. A first wireless signal (e.g., a radio frequency (RF) signal) may be employed to charge the device. A second wireless signal of a different type (e.g., an infrared (IR) signal) may be employed for inter-device communication. An example device may comprise a power module to receive a first wireless signal, a transmitter to transmit a second wireless signal, and a charging control module. The first wireless signal may be for conveying power from a charging device to the device, the second wireless signal may be for transmitting information from the device to the charging device, and the charging control module may be to cause the transmitter to transmit the second wireless signal based on an indication received from the power module.

Power delivery including out-of-band communication

Techniques for proximity sensing in a wireless power transmitter in a system, method, and apparatus are described herein. For example, an apparatus may include a transmitter coil configured to generate a magnetic field. The apparatus may also include a controller configured to reduce a strength of the magnetic field based on a proximity detection of an object.

Controlling a wireless power transmitter based on human presence

Transmission power control methods and devices are described In a transmission power control method, a specific absorption rate (SAR) is calculated based on a transmission power of the communication device and a proximity distance of the communication device with an external object A time average specific absorption rate can be calculated based on the SAR A power absorption budget value can be calculated based on the time average specific absorption rate and a time average specific absorption rate threshold value Further, the transmission power of the communication device can be adjusted based on the power absorption budget value
