Abstract
A head-mounted wearable device (HMWD) with a form factor of eyeglasses incorporates hinges between a front frame and temples. The hinges provide a fully enclosed passage for a flexible printed circuit (FPC). The FPC allows electrical connectivity between devices in the front frame and in the temple. The hinge includes a cam device that provides a biasing force that allows the temples to remain in one of four configurations: closed, transit, neutral, and maximum neutral. When in the transit configuration the biasing force provided by the cam device tends to move the temples towards the closed configuration. When in the maximum neutral configuration the biasing force provided by the cam device tends to move the temples towards the neutral configuration. During use, this biasing of the temples provides a gentle clamping force that assists in maintaining the HMWD on the user's head.
