Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: This disclosure describes systems, methods, and devices related to enhanced power management. A device may identify one or more first radio frequency waves received from a second device during a time period. The device may determine a first transmission power associated with a first radio frequency wave of the one or more first radio frequency waves. The device may determine a time-averaged power density associated with the one or more first radio frequency waves. The device may determine a transmission power limit. The device may send an indication of the transmission power limit to the second device.
