Eric X. Zhou - San Jose CA, US

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 wireless charging mat and method of operating the same. The wireless charging mat includes a detection system configured to determine a location and an orientation of an electronic device on the wireless charging mat. The location and orientation are determined based on detected locations of one or more structural features of the electronic device. The wireless charging mat is operated according to the detected location and orientation.
