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 primary receiving coil. 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.

Abstract: Contacts that may be highly corrosion resistant, may be readily manufactured, and may conserve precious materials. One example may provide contacts having a layer of a precious-metal alloy to improve corrosion resistance. The precious-metal-alloy layer may be plated with a hard, durable, wear and corrosion resistant plating stack for further corrosion resistance and wear improvement. The resources consumed by a contact may be reduced by forming a bulk or substrate region of the contact using a more readily available material, such as copper or a material that is primarily copper based.

Abstract: Embodiments describe a wireless charging device including a housing having a charging surface and first and second walls defining an interior cavity, and a transmitter coil arrangement disposed within the interior cavity and configured to generate a time-varying magnetic flux and an electric field during wireless power transfer, where each of the plurality of transmitter coils has a central axis positioned a lateral distance away from the central axes of all other transmitter coils of the plurality of transmitter coils. The wireless charging mat also includes an electromagnetic shield positioned between the transmitter coil arrangement and the first wall, an interconnection structure positioned within the interior cavity between the transmitter coil arrangement and the second wall, and a ferromagnetic shield positioned within the interior cavity between the transmitter coil arrangement and the interconnection structure, the ferromagnetic shield is configured to redirect the magnetic flux away from the interconnection structure.
