US Patent 11422384 Conductive connection through eyewear hinge

An eyewear device provides for routing a flexible conductive element or conductor through a hollow interior of a hinge mechanism that connects a temple of the eyewear device to its lens-supporting frame. The conductor establishes an electrically conductive connection between electronic components housed in the frame and the temple respectively. The hinge mechanism comprises a pair of hinge pieces that defines a composite conduit through the hinge mechanism, the conduit and hence the conductor routed through the passage being hidden or obscured from external view in any operational position of the hinge mechanism.
