Abstract: Embodiments describe a wireless power receiving module to receive magnetic flux for wireless power transfer. The wireless power receiving module includes a receiver coil comprising a single length of wire wound into a plurality of turns, an electromagnetic receiver shield coupled to a first side of the receiver coil, a ferrite layer coupled to a second side of the receiver coil opposite of the first side, the ferrite layer positioned to redirect magnetic flux during the charging event to improve charging efficiency, and a thermal mitigation shield comprising a thermally conductive layer adhered to an electrically conductive layer where the electrically conductive layer is coupled to ground, and where the ferrite layer is sandwiched between the thermal mitigation shield and the receiver coil.

Abstract: A wireless transmitter device is configurable and operable to transfer energy to multiple receiver devices at the same time. The transmitter device is configured to enable one or more sections of a charging surface to transfer energy by selectively choosing one or more conductive traces in the transmitter device based on the position of the receiver device on the charging surface. The size and shape of each section of the charging surface that is used to transfer energy to a receiver device can change dynamically based on each receiver device. Additionally, the process of transferring energy to each receiver device may be adjusted during energy transfer based on conditions specific to each receiver device.

Abstract: Methods of and systems for directing flux from a transmit coil to a receive coil within an inductive power transfer system are disclosed. For example, a transmit coil may be shielded with a contoured shield made from a ferromagnetic material. The contoured shield may contour to several surfaces of the transmit coil so as to define a single plane through which flux may be directed to a receive coil.

Abstract: This disclosure relates to the inductive charging of portable electronic devices. In particular, a charging assembly is disclosed that allows a portable electronic device to be charged in multiple orientations with respect to a charging device. The charging assembly includes two or more separate inductive receiving coils. The inductive receiving coils can be arranged orthogonally with respect to one another by wrapping one or more secondary receiving coils around a ferritic core having two legs extending in different directions from a joint region. By orienting the receiving coils orthogonally with respect to one another, the likelihood of at least one of the receiving coils being aligned with a charging field emitted by a charging device increases substantially.
