    Abstract: Embodiments describe a portable electronic device that includes a housing having an interface surface and an inductor coil disposed within the housing and comprising a conductive wire wound in a plurality of turns about a center point and in increasing radii such that the inductor coil is substantially planar. The portable electronic device further includes charging circuitry coupled to the inductor coil and configured to operate the inductor coil to wirelessly receive power and wirelessly transmit power, control circuitry coupled to the charging circuitry and configured to instruct the charging circuitry to operate the inductor coil to wirelessly receive power and to wirelessly transmit power, and a device detection coil coupled to the control circuitry and configured to detect the presence of an external device on the charging surface, the device detection coil is configured to operate at a different frequency from the inductor coil.

    Abstract: A cold worked stainless steel bezel for a portable electronic device is provided. The bezel is secured flush to a housing to form part of the case of the portable electronic device. A brace that includes a slot for receiving a wall extending from the bezel is fixed to the housing. When the bezel engages the housing, the wall of the bezel is inserted in the slot of the brace and releasably held by a spring that engages both the brace and the wall. The bezel can be released by disengaging the spring, (e.g., using a special tool or a magnetic field). Because the bezel is manufactured from cold worked stainless steel, it is hard and resistant to impacts. Cold worked steel also facilitates manufacturing within design constraints and tolerances, and requires very little machining after manufacturing to comply with those constraints.

    Abstract: This is directed to connecting two or more elements using an intermediate element constructed from a material that changes between states. An electronic device can include one or more components constructed by connecting several elements. To provide a connection having a reduced or small size or cross-section and construct a component having high tolerances, a material can be provided in a first state in which it flows between the elements before changing to a second state in which it adheres to the elements and provides a structurally sound connection. For example, a plastic can be molded between the elements. As another example, a composite material can be brazed between the elements. In some cases, internal surfaces of the elements can include one or more features for enhancing a bond between the elements and the material providing the interface between the elements.
