    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: 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.

    Abstract: A dual subscriber identity module (SIM) card connector is provided that includes a lower connector housing portion having a bottom surface and an upper connector housing portion having a top surface. The upper connector housing portion is coupled to the lower connector housing portion to define an opening for a receiving space between the upper and lower connector housing portions. The opening and receiving space are sized and shaped to slidably receive a SIM card tray. The connector includes a first plurality of electrical contacts disposed at the bottom surface of the lower connector housing portion and configured to make contact with a first SIM card disposed on a first side of the SIM card tray when the tray is received within the receiving space. The connector includes a second plurality of electrical contacts disposed at the top surface of the upper connector housing portion and configured to make contact with a second SIM card disposed on a second side of the SIM card tray opposite the first side when the tray is received within the receiving space.
