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: A computing device includes a charging coil for producing a charging current when placed in a magnetic field of a wireless power transmitter. A wireless charging operating frequency is associated with wireless charging of a battery of the computing device by the charging coil and the wireless power transmitter. An electrically conductive substrate has a plurality of gaps for reducing eddy currents when the electrically conductive substrate is disposed between the charging coil and the wireless power transmitter during charging of the battery. A plurality of filters each electrically bridge a respective one of the gaps. Each filter attenuates signals within a range of frequencies including the wireless charging operating frequency.

Abstract: An apparatus is described. The apparatus includes a transmission coil and a power amplifier. The power amplifier includes a microcontroller and a memory. The memory includes instructions to determine electric current output of the power amplifier, perform a lookup of load reactance range based on target electric current, detect load impedance, calculate reactance based on the load impedance, determine if reactance is within the load reactance range, and adjust reactance shift compensation to bring the reactance within the load reactance range if the reactance is not within the load reactance range.

Abstract: Described herein are techniques related one or more systems, apparatuses, methods, etc. for reducing induced currents in a apparatus chassis. For example, a fractal slot is constructed in the apparatus chassis to reduce the induced currents, and enhance passage of magnetic fields through the apparatus chassis. In this example, the fractal slot may include a no-self loop fractal space filling curve shape to provide high impedance to the induced currents.
