Abstract: An eyewear device has a lens retention mechanism that establishes electrical contact between onboard electronics and a lens ring by a resiliently compressible electrical contact member, such as a spring washer, located within a housing defined by a body of the eyewear device. The retention mechanism can further include a lock screw that is selectively engageable with the lens ring to allow disposal between retention and release of a lens by the lens ring, the lock ring being captured in the housing such as to resist removal of the lock screw from the housing when the lens ring is released for lens removal.

Abstract: An antenna system includes a loop conductor and non-loop conductor configured to provide respective loop and dipole antenna functionality. A signal feed mechanism connects to both conductors at a signal feed point for simultaneous signal transceiving. The non-loop conductor comprises two elongate arms with an offset feed point creating shorter and longer arms, where the longer arm has increased width via a loop-shaped portion. When incorporated in eyewear devices, the loop-shaped portion extends circumferentially along a lens holder to retain lenses. The conductors may be configured through a diplexer for different frequency domains, with the non-loop conductor serving as a GPS antenna and the loop conductor as a data communication antenna. The radiation patterns of the conductors may be substantially orthogonal when driven by the signal feed mechanism. The system provides integrated antenna and mechanical functionality in wearable devices.

Abstract: A housing assembly for an electronics-enabled device includes a housing wall having parallel inner and outer faces, with a hinge base affixed through the wall. The hinge base has a shank extending through the wall and a joint mount exterior to the housing for hingedly mounting an external component. An anchor plate inside the housing is welded to the shank, preventing axial withdrawal of the hinge base by obstruction against the inner face. The welded connection rotationally keys the anchor plate to the hinge base. The assembly enables integration of electronics components mounted on the anchor plate, which can serve as a thermal conductor between heat-generating components and an external heatsink via the hinge base. In electronics-enabled eyewear, the hinge base provides hinged connection of a temple to an eyewear frame. Manufacturing involves locating the hinge base and anchor plate, translationally fastening them together threadedly, and spot-welding for rotational keying.
