Assignee:

Apple Inc. - Cupertino CA

International Classification:

H02J 50/90
H01F 7/02

Abstract:

A bimodal annular magnetic alignment component can be included in an electronic device that attaches to other electronic devices using a magnetic alignment system that includes a primary annular alignment component and a secondary annular alignment component having complementary (and fixed) magnetic orientations. In a bimodal alignment component, a set of alignment magnets can be reoriented or shifted between a first position in which a magnetic orientation of the bimodal alignment component is complementary to a primary annular alignment component and a second position in which a magnetic orientation of the bimodal alignment component is complementary to a secondary annular alignment component. A bimodal electronic device incorporating a bimodal alignment component can be interchangeably attached to another device via either a primary annular alignment component or a secondary annular alignment component.

Abstract:

A case a portable listening device. The case includes a housing having an interior space to receive the portable listening device; a lid attached to the housing; a rechargeable battery and first and second wireless power receiving elements configured to receive electric charge from a wireless power transmitter during a charging event. The case further includes switching circuitry that is configured to disable one of the first or second wireless power receiving elements during a charging event when the disabled element is receiving power less efficiently than the other element.

Abstract:

A shield for redirecting magnetic field generated from a plurality of transmitter coils includes a ferromagnetic structure divided into segments by a plurality of boundary regions, each segment comprises a first material having a first magnetic permeability and each boundary region comprises a second material having a second magnetic permeability lower than the first magnetic permeability, where the plurality of boundary regions are configured to resist a propagation of magnetic field from a first area of the ferromagnetic structure to a second area of the ferromagnetic structure, where the first area intercepts the magnetic field generated from at least one active transmitter coil of the plurality of transmitter coils.
