  • Patent number: 10241346
    Abstract: Disclosed are an apparatus and method for providing additional degrees of freedom for diffraction gratings of an output waveguide in a near-eye display device. The near-eye display device includes an imager to generate an image based on light from a light source. The device further includes a waveguide to input a light wave representing the image received from the imager and to output the light wave representing the image toward an optical receptor of a user. The waveguide includes a plurality of diffractive optical elements (DOEs) in a common light path from an input of the waveguide to an output of the waveguide. The DOEs include a plurality of periodic diffraction patterns. Each of the periodic diffraction patterns is represented by a diffraction pattern vector. The periodic diffraction patterns are determined such that a vector summation of the diffraction pattern vectors equals zero.

  • Patent number: 10228110
    Abstract: An handheld illuminating device with orb-shaped lens for enhancing forward and lateral visibility including a flashlight having at least one light source that emits light rays through an orb-shaped lens. The orb-shaped lens is semi-spherical and adapted to disperse the light rays through a substantially 270° arc of uniform light for illuminating more than one area around the user, diffusing the light rays to soften the illumination from the light source, and eliminates shadows that are inherent in flat or curvilinear lenses. A reflector reflects light rays from the light source to the orb-shaped lens. A power supply powers the light source. A switch regulates power and intensity of the light source. A transparent cover protects the orb-shaped lens from physical damage.
