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: This disclosure describes a portable electronic device that includes an inductive charging receiver for receiving power wireless from a charging device. The portable electronic device includes a device housing including a wall having a channel formed in an interior-facing surface of the wall. The portable electronic device also includes an inductive coil assembly for receiving power wirelessly that is coupled to the interior facing surface. The inductive coil assembly is a flat coil that includes concentric loops of electrically conductive material that define a central opening. A first electrical lead extends away from a peripheral portion of the flat coil and a second electrical lead extends from the central opening, into the channel formed in the back wall and beneath one side of the concentric loops.

Abstract: An inductive charging dock is disclosed that includes a charging dock housing defining an interior volume. The inductive charging dock housing is configured to support a portable electronic device during a wireless charging operation and includes a radio frequency (RF) transparent window. An induction coil is disposed within the interior volume and configured to generate a magnetic flux that exits the charging dock housing through the RF transparent window.
