Patent number: 10007113Abstract: In a motor vehicle, a display device has a display area displaying an image projected by an optical device by way of a reflection area as a virtual image. The optical device has at least one reflector and an actuator which moves the reflector. The actuator includes a shape memory material, which is designed to be deformed by a temperature-dependent phase transition and thereby move the reflector. By the provision of a thermal shape memory actuator that functions without an electric current, the optical path can be changed, so that overheating of internal temperature-sensitive components of the display device can be prevented in a way that is particularly inexpensive and efficient in terms of installation space and it is also possible to dispense with electronic sensing, evaluation and activation entirely.Type: GrantFiled: April 30, 2015Date of Patent: June 26, 2018Assignee: AUDI AGInventor: Christian Wall

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.
