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: A battery pack comprises a pair of physically separate battery cells share a single protection circuit module (PCM). Each further saw comprises a respective pair of electrodes, with both pairs of electrodes being connected to a single, common protection circuit board (PCB) of the PCM. The common PCM may be located in a spacing between adjacent ends of the batteries such that a widthwise dimension of the PCB has an upright orientation between the two batteries.

Abstract: An electronic device includes a heat generating component, an electrical ground, a radio-frequency (RF) sensitive component, a conductor extending from the heat generating component to the electrical ground, and a non-metallic barrier at least partially surrounding the conductor and disposed between the conductor and the RF sensitive component. An electronic component includes a heat source, an electrical ground, a non-conductive body defining a pathway extending from the heat source to the electrical ground, and a conducting material disposed in the pathway.

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: Eyewear that includes a frame supporting an optical element. The frame has a first side and a second side. The eyewear also includes a temple adjacent the first side of the frame. The temple includes a first portion adjacent the frame and a second portion releasably connected to the first portion. An electronic device is provided in the releasable second portion. The electronic device may be passive or active, such as a battery configured to power the eyewear. The electronic device may communicate with an electronic component in the first portion, and may also operate independently when the second portion is removed.

Abstract: A head-mounted device may include display projectors and waveguides. The head-mounted device may have a head-mounted housing in which the display projectors and waveguides are mounted. The head-mounted housing may have a housing wall forming cavities containing the display projectors and waveguides. A moisture-impermeable cover may be used to cover and protect each of the display projectors. The cover may be formed from an elastomeric sock. The sock may have an opening that allows the display projector to emit image light that is received by a corresponding one of waveguides. Partitions may also be formed in the housing to block moisture and other contaminants. An elastomeric gasket or bellows serving as a partition may be used to separate a display projector cavity from a waveguide cavity.

Abstract: An antenna system comprises a combination of a loop antenna and a non-loop antenna. The loop antenna and the non-loop antenna is connected in common to a transceiver mechanism or signal feed mechanism. The non-loop antenna is in some embodiments provided by a dipole conductor. An eyewear device incorporates the antenna system, a loop conductor and a dipole conductor of the antenna system being integrated in a body of the eyewear device. The loop conductor may be provided by a lens ring that extends around a lens held by the body. The lens ring may serve both as loop conductor and as a lens retention mechanism.

Abstract: Eyewear devices including a tether and methods for identifying proper installation of the tether are disclosed. An eyewear device includes transmission lines extending through the temples to electrical and electronic components positioned adjacent to edges of a frame. A tether is attached to the temples to enable power and communication flow between the electrical and electronic components rather than through the frame. Proper installation is identified based on communications passing between the electrical and electronic components via the tether.

Abstract: Electronic devices may be provided that contain multiple housing portions. The housing portions may be coupled together using hinges. The hinges may include hinges based on a three-bar linkage, hinges based on a four-bar linkage, hinges with slotted members, hinges formed from flexible support structures, and hinges based on flexible housing structures. Flexible displays may be mounted to the housing portions overlapping the hinges. When the housing portions in a device are rotated relative to each other, the flexible display may bend. The hinge may be configured to allow the flexible display to be placed in a front-to-front configuration in which an active side of the display faces itself or a back-to-back configuration. Engagement structures may be used to help the housing grip external objects and to hold the housing portions together. The hinges may be provided with rotational detents to help hold the flexible display in desired positions.

Abstract: An electronic device having a housing structure that is configured to receive at least one glass cover is disclosed. The glass cover serves to cover a display assembly provided within the electronic device. The glass cover can be secured to the housing structure so as to facilitate providing a narrow border between an active display area and an outer edge of the housing structure. The enclosure for the electronic device can be thin yet be sufficiently strong to be suitable for use in electronic devices, such as portable electronic devices.
