Over-extension hinge for a pair of augmented-reality glasses

A hinge system of a pair augmented-reality glasses, comprising:

• a primary hinge that includes a primary pivot axis defining movement between a temple arm attached to a glasses frame, wherein the primary pivot axis provides an axis of rotation during closure and extension of the temple arm relative to the glasses frame between a first position and second position;
• a secondary hinge that includes a secondary pivot axis along an outer edge of the temple arm, wherein the secondary pivot axis is parallel to the primary pivot axis, wherein the secondary pivot axis provides an axis of rotation during an over-extension of the temple arm relative to the frame;
• and
• an AR projection system coupled to the frame;
• a battery located in the temple arm that is configured to provide power to the AR projection system coupled to the frame.
