    Abstract: A head mounted wearable computing device includes a frame including arm portions rotatably coupled to a front frame portion, with electronic components housed in and/or on the front frame portion and the arm portions. Cables run through hinge mechanisms rotatably coupling the arm portions and the front frame portion for connection of electronic components in the arm portions and the front frame portion. The hinge mechanism includes a dual pivot structure that guides the bending of cables through the hinge mechanism through approximately 90 degrees of bending through two pivot points. The dual pivot structure reduces localized strain on the cable through the range of motion of the hinge mechanism. The dual pivot structure allows for a rotation through the range of motion with little to no extra cable length to accommodate the bending of the cable.

    Abstract: Systems and methods for adjusting a level of force exerted by the temple arm portions of a frame of a head mounted wearable device are provided. Hinge mechanisms that provide for the rotatable coupling of a temple arm portion to a rim portion of a frame of the head mounted wearable device, or glasses, may include a rotation mechanism that facilitates rotation of the temple arm portion relative to the rim portion, and a biasing mechanism that can be adjusted to apply a desired level of lateral force to a head of a user wearing the glasses. The hinge mechanisms may allow for adjustments to biasing rates and/or pre-load levels and/or amounts of temple arm portion rotation prior to engagement to adjust the applied force to desired levels and maintain user comfort.

    Abstract: Display systems, such as near eye display systems or wearable heads up displays, may include a laser projection system having an optical engine and an optical scanner. Light output by the optical engine may be directed into the optical scanner as two angularly separated laser light beams. The angularly separated laser light beams typically have different angles of incidence on a second scan mirror of the optical scanner. Respectively different levels of magnification are applied to the beam diameter of each of the angularly separated laser light beams in a first dimension, such that the angularly separated laser light beams have respectively different beam diameters upon incidence at the second scan mirror. In some embodiments, the different beam diameters of the angularly separated laser light beams result in regions of incidence of each of the angularly separated laser light beams on the second scan mirror being equal or substantially similar.

    Abstract: A head-mounted display (HMD) system includes a lens element supported by a support structure. The lens element includes a waveguide that includes an incoupler, an outcoupler, and an exit pupil expander. The incoupler is disposed within a first area of the waveguide. The outcoupler is disposed within a second area of the waveguide. The exit pupil expander is disposed within a third area of the waveguide. An anti-reflection coating is formed via fabrication used to form the incoupler, the outcoupler, and the exit pupil expander. The anti-reflection coating is disposed within a fourth area of the waveguide different than the first, second, and third areas of the waveguide.

    Abstract: There is provided an optical element including a light guide, an incoupler, and a beam splitter disposed in an optical path of a display beam between the incoupler and a light engine to generate the display beam. The display beam may comprise first and second beams. The beam splitter may split the display beam to form a first offspring beam including the first beam and a first portion of the second beam, and to form a second offspring beam including a second portion of the second beam. The first and second offspring beams may be incident upon the incoupler at first and second incidence positions respectively. The first incidence position may be different than the second incidence position. The incoupler may direct at least a portion of each of the first and second offspring beams into the light guide to form incoupled first and second offspring beams respectively.

    Abstract: Systems, devices, and methods for accommodating multiple sets of laser light sources in an optical engine of a display system such as a laser projection system are described. Laser light beams may be combined via wavelength-, polarization-, and/or angular-separation-based techniques. First and second sets of laser light beams may be angularly separated such that different sets of partially overlapping pixels are projected by the system, thereby increasing the display pixel density and/or an expanding the field of view of the display. One or more laser die may be mounted to each submount of the optical engine. For embodiments with two laser dies on each submount, collimating lenses may introduce angular separation between laser light beams output by each pair of commonly mounted laser dies. A retroreflector prism may be disposed at a beam combiner to provide a compact extension of the optical path through the beam combiner.
