Patent number: 10001646Abstract: A head-up display includes a concave mirror actuator that changes, based on external instructions, a reflection angle by which a concave mirror reflects display light. A drawing unit includes a beam generator, a scanner, an optical actuator, and a controller, The beam generator emits a beam, and the scanner scans the beam in two dimensions by moving a reflection surface to draw an image. The optical actuator changes an angle of incidence of when the beam is emitted to the scanner. The controller drives the optical actuator to change the angle of incidence such that display light distortions generated at the concave mirror are offset by display light distortions generated at the scanner.Type: GrantFiled: May 13, 2015Date of Patent: June 19, 2018Assignee: DENSO CORPORATIONInventors: Hiroshi Ando, Makoto Sakai

Patent number: 10001648Abstract: Embodiments herein describe AR systems that provide occluded AR content to a user while maintaining the perspective of the user. In one embodiment, the AR system includes an optical cloak that contains a mask display device and an AR display device and one or more focusing elements for focusing light captured from the user's environment. As the light enters the optical cloak, the mask display device occludes a portion of the user's view to generate a black silhouette. The AR system then combines AR content displayed by the AR display device with the image of the environment such that the location of the AR content overlaps with the location of the black silhouette. Furthermore, the spacing and characteristics of the focusing elements is set to maintain the perspective of the user as the light passes through the optical cloak.Type: GrantFiled: April 14, 2016Date of Patent: June 19, 2018Assignee: Disney Enterprises, Inc.Inventor: Quinn Yorklun Jen Smithwick

Patent number: 10001651Abstract: A display device includes a first diffraction element configured to diffract image light and a second diffraction element disposed on an optical path between a light source and the first diffraction element. The first and the second diffraction element emit light beams that have highest diffraction efficiencies in one direction when a single wave light enters from directions of normals. If the sum of the number of reflections of light and the number of times of intermediate image generation between the second diffraction element and the first diffraction element is an even number, in the first and the second diffraction element, the directions of the diffraction light having the highest diffraction efficiencies are output when light enters from the directions of the normals are the same with respect to the directions of the normals to the incident planes. If the sum is an odd number, the directions are opposite.Type: GrantFiled: February 21, 2017Date of Patent: June 19, 2018Assignee: SEIKO EPSON CORPORATIONInventors: Toshiyuki Noguchi, Masatoshi Yonekubo

Patent number: 10001654Abstract: A display system is provided that combines the use of a display element with a beamsplitter and at least one retroreflector to provide an image (2D or 3D depending upon the output image from the display element) that appears to be floating in space some distance from the beamsplitter. For example, light that is bounced off/reflected and/or that is transmitted through the beamsplitter may be reflected from the reflective surface of the retroreflector toward the beamsplitter. The beamsplitter directs this light, through reflection or transmission, into a viewing space such that the 2D or 3D image can be viewed by a viewer as it appears to float a distance from the nearest surface of the beamsplitter and, typically, some distance above the ground/floor upon which viewers are walking. The floating image may be relatively bright so that it is viewable in low and brighter light conditions.Type: GrantFiled: July 25, 2016Date of Patent: June 19, 2018Assignee: Disney Enterprises, Inc.Inventors: Daniel M.
