A head-mounted wearable device utilizes electronics placed in one or more of a left temple or a right temple. The temples are joined to a front frame using hinges. The hinges provide passageways, slots, or other openings to permit passage of a flexible printed circuit (FPC) within an open core of the hinge. The FPC allows communication between the left temple and the right temple. During motion of the hinge, the FPC may twist such that the ends within the hinge are rotated relative to one another while remaining substantially parallel to one another. The overall length of the FPC passing through the hinge remains substantially unchanged between the hinge being open or closed. The FPC remains protected within the hinge and is minimally displaced, preventing the introduction of a crease in the FPC at a hinge line.

A wearable device and an electrical connector with magnetic attraction are provided. The wearable device includes a first body and a second body. The first body has a first pivotal structure and two inner walls respectively provided with a first magnetic attraction member and a plurality of first terminal structures. The second body has a second pivotal structure, and is provided with a second magnetic attraction member and a plurality of second terminal structures. When the second pivotal structure is pivotally connected to the first pivotal structure, the second body is rotatable relative to the first body, and the first and second magnetic attraction members are moved by following the first and second bodies. When the first and second magnetic attraction members are magnetically attracted to each other so as to fix the first body and the second body, the first terminal structures contact the second terminal structures.

An eyeglass frame is disclosed comprising a bridge and two rims connected by the bridge. Each rim is configured to contain a lens. The eyeglass frame also comprises two split end pieces. Each split end piece comprises a first portion and a second portion. Each split end piece is coupled to and extends outward from a corresponding rim of the two rims on a side of the corresponding rim opposite the bridge. The eyeglass frame further comprises two temples. Each temple comprises a lock on an end of the temple. The lock is configured to at least partially contain both the first portion and the second portion of the split end piece and secure the temple to the corresponding rim and secure the lens within the corresponding rim.

Detachable spectacle frame formed by a front, which in turn includes some rims, a bridge, some lugs and some nose pads; a pair of temples; in which each of the temples includes a hinge to engage the front, and a terminal end, where each of the rims and their corresponding temples has a defined slot. The removable frame being characterized in that each of the lugs further includes a laminar projection, finished by a hook; the hinge of each of the temples incorporates a recess and a kink and; further incorporates a fastening clip engaging the lug.

A screwless hinge system for connecting a temple to a front frame portion of eyewear includes a hooked tab with a single hook and a base. The hooked tab extends through the front frame portion and a u-spring until the base engages the frame. A temple receiver of a temple compresses the u-spring and engages the single hook, allowing for opening and closing of the temple and removal and replacement of the temple without tools.

Eyewear including an optical functional member, control electronics, and a sealed electrical connective element connecting the electronics to the optical functional member. The connective element can directly connect the electronics to the optical functional member, or can connect through an intermediate contact, e.g., a plug-and-receptacle. The connective element can be muted from the electronics, around a rimlock of the eyewear to the optical functional member. The connective element can be a conductive compressible member, such as conductive rubber. In some embodiments, the connective element can be a multiconductor cable.

Various aspects include audio eyeglasses with through-hinge wiring configurations. In particular aspects, audio eyeglasses include: a frame for resting on a head of a user, the frame comprising: a lens region; a pair of arms extending from the lens region; and a hinge coupling the lens region and one of the pair of arms, the hinge comprising: a body; a friction element coupled to the body for damping the movement of the arm relative to the lens region; and a cavity within the body, the cavity sized to accommodate a cable extending therethrough, the hinge permitting movement of the arm relative to the lens region; and an electro-acoustic transducer at least partially housed in the frame and comprising a sound-radiating surface for providing an audio output.

A head-mounted wearable device incorporates a channel inset into a front frame. A flexible printed circuit (FPC) is arranged within the channel and allows communication between a left side of the front frame to a right side. Using the FPC, electronics in a left temple attached to the front frame are connected to the electronics in a right temple attached to the front frame. A retention piece is used to maintain the FPC within the channel, provide protection from an external environment, and so forth. The retention piece may comprise an overmold of silicone plastic.

An optical transmission hinge includes a first hinge body and a second hinge body. A pivot joint is formed between the first hinge body and the second hinge body. The pivot joint defines a pivot axis. A first optical element and a second optical element are positioned on the pivot axis, and the second optical element is spaced apart from the first optical element. An intermediary optical path that is coincident with the pivot axis extends between the first optical element and the second optical element. Temples and wearable heads-up displays including the optical transmission hinge are disclosed.

Eyewear including an optical functional member, control electronics, and a sealed electrical connective element connecting the electronics to the optical functional member. The connective element can directly connect the electronics to the optical functional member, or can connect through an intermediate contact, e.g., a plug-and-receptacle. The connective element can be routed from the electronics, around a rimlock of the eyewear to the optical functional member. The connective element can be a conductive compressible member, such as conductive rubber. In some embodiments, the connective element can be a multiconductor cable.
