Abstract
A hinge assembly for an electronic device. The hinge assembly includes a first component coupled to a second component by a cam. The cam includes a cylinder coupled to the first component and a bottom cap coupled to the second component by a fastener. The cylinder includes a first port and a second port, where an energy waveguide passes from the first component into the first port and through the second port into the second component. The first component rotates about an axis of rotation in relation to the second component from a first rotational position to a second rotational position. The first component is offset relative to the second component in the second rotational position. The offset includes a translation along an axis parallel to an axis of rotation and a rotation about the axis of rotation.

An assembly comprising:
- a hinge mechanism that couples a first component to a second component, the hinge mechanism including an axis of rotation about which the first component rotates relative to the second component, the hinge mechanism comprising:
- a cam coupled to the first component, the cam comprising a first port and a second port, and the relative position of the first port to the second port translates parallel to the axis of rotation as the first port rotates relative to the second port about the axis of rotation,
- wherein an energy waveguide passes through the first component into the first port and out of the second port into the second component.
An eyeglass assembly comprising:
- a frame holding at least one optical element;
- a temple arm;
- a hinge mechanism that couples the temple arm to the frame, the hinge mechanism including an axis of rotation about which the temple arm rotates relative to the frame, the hinge mechanism comprising;
- a cam coupled to the temple arm, the cam comprising a first port and a second port, and the relative position of the first port to the second port translates parallel to the axis of rotation as the first port rotates relative to the second port about the axis of rotation,
- wherein a wire passes through the temple arm into the first port and out of the second port into the front frame.
