  • Patent number: 10670858
    Abstract: Methods and apparatus for maintaining, adjusting and/or accurately determining the position of a moveable element, e.g., a moveable shaft mounted component are described. The moveable component may be, for example, a mirror or mirror support of a camera module. A hall sensor is used to measure distance to the moveable component. To facilitate the distance measurement a magnet is secured to the moveable component. The hall sensor is used to determine the distance between the magnet and sensor. A metal plate is placed along a side of one of the supports used to support the shaft to which the moveable component is attached. The magnet which facilitates distance measurement is attracted to the plate reducing the risk of side to side movement even when the shaft fits loosely in the supports and is rotated. The magnet facilitates distance measurements and reliable control of position relative to the sidewall plate.

  • Patent number: 10670862
    Abstract: In an optical display system that includes a waveguide with multiple diffractive optical elements (DOEs), gratings in one or more of the DOEs may have an asymmetric profile in which gratings may be slanted or blazed. Asymmetric gratings in a DOE can provide increased display uniformity in the optical display system by reducing the “banding” resulting from optical interference that is manifested as dark stripes in the display. Banding may be more pronounced when polymeric materials are used in volume production of the DOEs to minimize system weight, but which have less optimal optical properties compared with other materials such as glass. The asymmetric gratings can further enable the optical system to be more tolerant to variations—such as variations in thickness, surface roughness, and grating geometry—that may not be readily controlled during manufacturing particularly since such variations are in the submicron range.

  • Patent number: 10670872
    Abstract: An all-fiber optical beam switch mechanism includes a first length of fiber through which an incident optical beam having beam characteristics propagates along a first propagation path and which has a first refractive index profile (RIP). The first RIP enables, in response to an applied perturbation, modification of the optical beam to form an adjusted optical beam that is movable to propagate along a second propagation path. A second length of fiber is coupled to the first length of fiber and formed with multiple spaced-apart, non-coaxial confinement cores. A selected state of applied perturbation moves the second propagation path of the adjusted optical beam to a position of a selected corresponding one of the multiple confinement cores to confine and thereby direct the adjusted optical beam to a corresponding beam output location at the output of the second length of fiber.

  • Patent number: 10670874
    Abstract: An optical computed tomography system for comprehensive end-to-end verification of the delivered dose in phantoms is described. The optical computed tomography system includes a light source that emits light; a detector; and a light-collimating tank arranged between the light source and the detector. The light-collimating tank itself includes a transparent substrate having a recessed region formed therein; an incident light surface formed on the transparent substrate; and an exit light surface formed on the transparent substrate opposite the incident light surface and shaped to focus light toward a focal region located outside of the transparent substrate. In some configurations, the incident light surface is shaped to collimate light impinging on the incident light surface into parallel rays that pass through the tank towards the exit light surface.

  • Patent number: 10670880
    Abstract: A display image is superimposed and displayed on an outside image in a preferred manner. An optical system superimposes a display image displayed on a display device onto an outside image, and leads the display image to an eye of an observer. A display control unit controls the display size and the display position of the display image on the display device so that the display image is displayed in an image superimposition region (a flat region) detected from the outside image. For example, the display control unit controls the display state of the display image in accordance with the state of the image superimposition region in the outside image. Also, the display control unit performs control to selectively display the display image in a line-of-sight region or outside the line-of-sight region in accordance with the line of sight of the observer.

  • Patent number: 10670882
    Abstract: A pair of goggles with a lens assembly, a goggle frame, and at least one lens retention shelf is disclosed. The lens assembly includes a lens with a projection extending from the assembly. The goggle frame is made of a first material and has a frame aperture sized large enough to receive the projection from the lens assembly through it. The lens retention shelf is made of a second material harder than the first material and is disposed behind the frame. The first lens retention shelf includes a projection connector corresponding to the projection, the projection connector is aligned with the frame aperture and sized sized to receive and engage the projection with the goggle frame interposed between the lens retention shelf and the lens.

  • Patent number: 10670886
    Abstract: A customizable eyeglass system for use in any remote situation, and which is ideal for use in third-world countries or areas where electrical power and typical machinery for manufacturing eyeglasses is lacking. The system includes a frame with receivers for the temples to connect into and lock into place. A pair of customizable lenses is connected to the front of the frame. The lenses can be rotated to dial in the correct prescription for the patient and then locked into place as well. Thus, the invention corrects near and distance vision while also correcting astigmatism. If adjustments need to be made, the patient can easily unlock the lenses, rotate them to a proper orientation for proper sight, and then lock the lenses into place again. The replacement lenses can be used with optical enhancement scopes such as telescopes, firearm scopes, and binoculars.
