Abstract: The disclosure generally relates to methods, system and apparatus to optimize wireless charging while allowing FM radio reception. In an exemplary embodiment, presence of an active FM radio on a wireless platform is detected and the active FM channel is identified. To reduce radio frequency interference between the wireless charging magnetic field and the FM channel, the PTU may adaptively shift the A4WP frequency. The disclosed embodiments improve user experience with FM radios in wireless charging systems.

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.

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: 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: In an example, a mobile computing device such as a tablet, laptop, or convertible is operable to couple to a docking station via high-frequency wireless such as WiGig at 60 GHz. Because high-frequency signals are highly directional, the mobile computing device is provided with a high-frequency antenna operable as a rotor. In one embodiment, the antenna is freely hinged to a gravitational pivot, and pivots toward the docking station responsive to gravitational torque. In another embodiment, an actuator drives the antenna to a correct angle responsive to a rotational sensor. In this case, an angle sweep may be performed around a midpoint to identify a best angle for high-frequency communication.
