Patent number: 6151081Abstract: A system and a method for controlled concurrent viewing of images, in their entirety, by the use of a dual viewer controllable dual display system having the added capability of individually presented resolution is disclosed. In operation, a viewer first selected image is provided by a first controllable display device and a viewer selected second image, typically different from the first, is provided by a second controllable display device. A viewer looks through the second display and sees the image presented by the first display and the image presented by the second display provided at the plane of the first display. Additionally, the displays can be interactive, in that an image or event provided on one display results in the presentation of an image or other data on the other display, all the while allowing the viewer to select from other information. Also the position of one image can be varied with respect to the other image.Type: GrantFiled: December 2, 1997Date of Patent: November 21, 2000Assignee: Raytheon CompanyInventors: Ronald S.

Patent number: 5924377Abstract: A modular enclosure system particularly suited for use aboard a ship comprises a modular enclosure which is easily installed into and removed from an exoskeletal frame that is shock-mounted to a fixed surface, such as the deck of a ship. An enclosure is installed by placing it within a respective frame via complementary guide rails. A securing mechanism locks the enclosure into place within the frame, and an ejection mechanism enables an enclosure to be easily removed for purposes of maintenance, repair or reconfiguration, or in the event of an emergency. The enclosures are preferably water-tight and float if ejected into the sea. Rubberized boots surrounding all points of entry enhance the survivability of the enclosures in a nuclear/biological/chemical (NBC) environment. Shock-mounting the frames to the deck eliminates the need to shock-mount individual pieces of equipment and enables the use of cheaper and more readily available commercial off-the-shelf equipment.Type: GrantFiled: June 26, 1997Date of Patent: July 20, 1999Assignee: Raytheon CompanyInventors: Gregory P.

Patent number: 5788352Abstract: A projection system wherein two or more separate display sources, such as high brightness sources, or active matrix liquid crystal display (AMLCD) or other flat panel displays are used to write information directly onto a display screen, or onto a photoactivated reflective light valve for projection onto the display screen. Sequential imaging apparatus is used to alternately generate first and second images for display. For example, such images are coupled to the photoactivated reflective light valve and an illumination source is employed to illuminate the light valve and project a composite image onto the display screen. The flat panel displays may be transmissive, reflective, or self-emissive with the use of an optical shutter. A writing illumination source is used for non-self-emissive flat panel displays. Using high brightness display sources, the images may be directly written onto the display screen without the use of the reflective photoactivated light valve and the illumination source.Type: GrantFiled: October 25, 1994Date of Patent: August 4, 1998Assignee: Hughes Aircraft CompanyInventors: John T. Montroy, John P. Garcia, Ronald S. Gold, Jerry E. Freeman

Patent number: 5676446Abstract: A light source system (10) for collecting and directing light. The light source system (10) includes light cubes (12) including an enclosure (22) substantially surrounding a light emitter (26). The enclosure includes a body (22) enclosing a cavity (24). A plurality of light pipes (32) are disposed to extend through the body into the interior of the cavity, so that the light pipes (32) carry light from inside to outside the cavity. By utilizing a plurality of these light cubes (12), the intensity of light can be controlled by combining light from a plurality of such light sources into a combiner unit (16) which combines the light from all of these sources into a single path. The intensity of light in the combiner output can be controlled by selectively turning on or off one or more of the light sources. The present invention thereby provides a high intensity light source which is rugged and easy to manufacture at low cost. The modular design provides built in redundancy and light intensity control.Type: GrantFiled: August 14, 1996Date of Patent: October 14, 1997Assignee: Hughes Aircraft CompanyInventor: Ronald S. Gold
