Patent number: 6072444Abstract: A head up display (HUD) mounting assembly (MA) enables the secure, yet flexible mounting of major HUD components within vehicles and particularly within the cockpit of an aircraft. Flexibility is desirable because of slight movement of airframe members during maneuvers and changing temperature and air pressure conditions, yet stability must be maintained in order to preserve optical alignment between the HUD projector and image combiner components. The inventive MA provides an integrated support for the HUD projector and image combiner thus improving optical stability over discretely mounted systems. The MA has a relatively rigid support arm attached to two end brackets, where one is a spring bracket and the other is an anti-twist bracket. The brackets are mounted to the ceiling of an aircraft cockpit to support the arm and to resiliently hold the HUD components in optical alignment.Type: GrantFiled: June 15, 1998Date of Patent: June 6, 2000Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: Fletcher A.

Patent number: 5867133Abstract: A dual use heads-up display panel for a vehicle may be orientated in a first orientation wherein it displays information onto the window of a vehicle. The display panel may be selectively moved to a facing-forward position wherein it directs information towards the operator of the vehicle. The control for the display panel determines which of the two positions the display panel is in, and modifies the information displayed on the panel accordingly. The information should be reversed in a mirror image between the two orientations such that it is properly orientated when read off of the windshield, and is also properly orientated when read from the facing-forward position. In a further feature, a convergent optical system, which may be a lens, is placed in the path of the light from the display panel when in the heads-up position. The lens causes the size of the information displayed on the windshield to be reduced such that its intensity is increased.Type: GrantFiled: December 13, 1996Date of Patent: February 2, 1999Assignee: UT Automotive Dearborn, Inc.Inventors: Daniel Toffolo, Silviu Palalau

Patent number: 5229755Abstract: Various indication display units, for vehicles provided with a head-up display including an indication projector with a display device at the ceiling of a vehicle and a reflecting device forwardly of a driver seat, have been introduced so far due to the fact that there are increasing requirements for space for the installation of many kinds of indicators in vehicles. The problem remains that the displayed image on the reflecting device can hardly be seen on the indication display unit of the conventional type when external strong rays of light are radiated to the above reflecting surface from outside the vehicle through the windshield, and a part of the ceiling reflected on the reflecting device together with the indicating image projected from the projector also causes a bad effect to the displayed image when the vehicle is illuminated by another vehicle following there behind.Type: GrantFiled: May 13, 1992Date of Patent: July 20, 1993Assignee: Yazaki CorporationInventor: Kunimitsu Aoki

The driver and power supply circuits associated with the display unit feature improved arrangements which attenuate surges and spikes. The voltage appearing on the grid of the VFD is controlled by a circuit which is responsive to a signal produced by a microcomputer which controls the illumination and which induces changes in the voltages applied across the filament of the VFD. The level of illumination can be automatically controlled by light sensor and illumination levels above default values which are automatically reset to optimal values each time the system is initially energized.Type: GrantFiled: April 12, 1989Date of Patent: April 13, 1993Assignee: Kanto Seiki Co., Ltd.Inventor: Masafumi Nagami

Patent number: 5198797Abstract: A heads up display arrangement for a vehicle comprises a combiner arranged on a front window panel, and a projector arranged for projecting a value of a frequency received by a radio receiver. During operation of an automatic tuning mechanism of the radio receiver, the value of received frequency is not outputted to the projector.Type: GrantFiled: April 12, 1991Date of Patent: March 30, 1993Assignee: Nissan Motor Co., Ltd.Inventor: Shigetoshi Daidoji

Patent number: 5123728Abstract: A rear screen projection system integrated into the passenger cabin of an airplane. The system has a projector that directs a picture into the inner cavity of a housing. Also attached to the housing is a screen that has a first surface that faces the audience and a second opposite surface exposed to the inner cavity of the housing. Located between the projector and the housing is a mirror that reflects the picture from the projector onto the second surface of the screen. The screen is transparent to light so that the audience can view the picture on the first surface of the screen. The mirror is positioned such that the distance between the projector and the top and bottom edges of the screen are essentially equal. The mirror is also positioned such that even with an overhead projector, the incidence of light is normal to the screen and the picture is directed down toward the audience.Type: GrantFiled: March 18, 1991Date of Patent: June 23, 1992Assignee: Sony Trans Com, Inc.Inventors: James H. Gradin, Donovan T. Nguyen

Patent number: 5071209Abstract: The invention provides a non-linear projection system, which includes a variable acuity non-linear holographic optical element (HOE), and an apparatus for creating the HOE. The projection system comprises a computer, a light valve which projects images generated by the computer, a lens train for focusing the images projected by the light valve, an HOE for the non-linear refraction of the focused images and a hemispherical viewing screen. The system additionally provides means for maintaining the center of the projected images in alignment with center of the field of view of an observer. The variation of the pixel size and spacing created by the system matches the variation of the human visual acuity of the observer permitting a realistic view to be presented while requiring a minimum of computer data to be generated and projected. The apparatus for creating the HOE utilizes a laser beam, three lens trains and a holographic recording medium.Type: GrantFiled: May 7, 1990Date of Patent: December 10, 1991Assignee: Hughes Aircraft CompanyInventors: David B. Chang, Norton L. Moise, I-Fu Shih

Patent number: 5059957Abstract: A CRT display system for a vehicle is provided, the system comprises a CRT for displaying images, vehicle information, or so forth, a liquid crystal panel assembly disposed in front of the CRT, a vehicle information sensor, and control means for the liquid crystal panel. The vehicle information sensor is adapted for determining whether the vehicle is running or not and whether an ambient light level is high or low to provide signals indicative thereof. The control means is operable to control the transmission factor of the liquid crystal panel so as to limit a visual angle for the driver in response to the signals output from the vehicle information sensor. When the ambient light level is low and the vehicle is running, the control means controls the liquid crystal panel assembly so as to reduce the transmission factor thereof to a first level with the result that no images from the CRT are projected to the driver through the panel assembly although passengers may clearly see the images.Type: GrantFiled: March 27, 1989Date of Patent: October 22, 1991Assignee: Nissan Motor Company, LimitedInventors: Tsuyoshi Todoriki, Shigeru Okabayashi, Masao Sakata
