Abstract: The disclosure relates to a method, apparatus and system to wirelessly charge a device. Specifically, the disclosed embodiments provide improved charging stations for increased active charging area. In one embodiment, the disclosure relates to an offset device for use with a Power Receiving Unit (PRU). The offset device includes a conductive layer supporting an aperture, the aperture aligned with an inner most coil loop of the PRU; and a first slot formed in the conductive layer extending from the aperture to an outside edge of the conductive layer.

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.
