  • Spring hinge with accommodation for flexible printed circuit
    Patent number: 11409130
    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.

  • System and method for generating white light for projectors
    Patent number: 11402617
    Abstract: A system and method of generating white light for a projection system in a compact form factor using laser diodes, a reflection system, and a phosphor target. Light emitted from the laser diodes can be directed towards a region of the phosphor target, where the phosphor target is excited and emits light in a desired spectrum in all directions. Some emitted light is collected by a collection lens. The emitted light collected by the collection lens can be combined with light from the original laser diodes to create white light for use in the projection system. Light emitted in a direction away from the collection lens can be redirected to the collection lens by the reflection system that employs a curved reflector on one side of the phosphor target and a flat reflector on the opposite side of the phosphor target.
