US Patent 11480802 Electronic eyewear featuring hinge circuit

An electronic eyewear device includes a frame having a first electronic subsystem that includes a near-eye graphical display, a temple portion having a second electronic subsystem, and a hinge assembly rotatably coupling the frame to the temple portion. According to an example, the hinge assembly includes a hinge core defining a hinge axis, a cover that spans a gap between the frame and the temple portion on at least one side of the hinge axis, and a flexible ribbon circuit electrically coupling the first electronic subsystem to the second electronic subsystem. In at least some examples, the flexible ribbon circuit spirals around the hinge core between the cover and the hinge core.
