    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: 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: 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: 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.

    Abstract: Techniques for wireless transmitting power are described. An example power transmitting unit includes a magnetic resonance-type transmit coil array comprising a plurality of coil elements, wherein each coil element is tuned to a same resonant frequency. The power transmitting unit also includes a power generating circuitry to deliver current to the transmit coil array to wirelessly power a device within an active wireless charging area of at least one of the plurality of coil elements. Each coil element exhibits a plurality of zero point distances and the spacing between neighboring coil elements corresponds with the plurality of zero point distances.
