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.

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.

Abstract: Examples are disclosed to track sport implements and/or objects of interest. An example apparatus includes a first coil to generate a first magnetic field having a first vertical component with a zero magnitude along a first line of interest and a second coil partially overlapped with the first coil, where the second coil is to generate a second magnetic field. The example apparatus also includes a sensor to measure a magnitude of the first magnetic field in the first line of interest and a processor to determine an object of interest has crossed the first line of interest based on the magnitude of the first magnetic field measured by the sensor.

Abstract: Example wirelessly powered unmanned aerial vehicles and tracks for providing wireless power are described herein. An example apparatus includes a track section having a transmitter coil to generate an alternating magnetic field and an unmanned aerial vehicle having a receiver coil. The alternating magnetic field induces an alternating current in the receiver coil when the unmanned aerial vehicle is disposed in the alternating magnetic field.

Abstract: In a wireless charging device that includes a resonator having coil windings, a magnetic field can be generated by the resonator. The wireless charging device can include a feed point connected to an inner winding of the coil windings of the resonator. The resonator can inductively couple with a power receiving unit such that the an outer winding of the coil windings limit Eddy current generation in one or more conductive surfaces positioned adjacent to the power receiving unit. The feed point can be selectively connected to the inner winding of the coil in a first mode of operation and the outer winding of the coil in a second mode of operation. The inner winding can have a larger current than the outer winding.

Abstract: Embodiments of the present disclosure provide techniques and configurations for controlled power level adjustment of a wireless charging apparatus. In one instance, the apparatus may comprise a charging module to radiate an electromagnetic field to wirelessly charge an electronic device in proximity to the wireless charging apparatus; and a control module communicatively coupled with the charging module to adjust a power level of the electromagnetic field, radiated by the charging module, in response to a determination of an environmental condition in relation to the wireless charging apparatus. The control module may be configured to receive information indicative of the environmental condition from multiple sources distributed between the apparatus and the electronic device, and make the determination based at least in part on the received information. The environmental condition may comprise a presence of human tissue in proximity to the wireless charging apparatus. Other embodiments may be described and/or claimed.

Abstract: Techniques for focusing the energy radiated by a wireless power transmitting unit are described. An example power transmitting unit includes a transmitter coil configured to generate a magnetic field to wirelessly power a device within an active wireless charging area. The power transmitting unit also includes a power generating circuitry to deliver current to the transmitter coil to generate the magnetic field. The power transmitting unit also includes a shield disposed around the transmitter coil to reduce the strength of the magnetic field outside of the active wireless charging area.
