Filed:

Aug 12, 2004

Appl. No.:

10/921357

Inventors:

Richard Wolfe - Londonderry NH, US

Assignee:

Kollsman, Inc. - Merrimack NH

International Classification:

G05D 1/00
G09B 9/08

US Classification:

701 10, 434 36

Abstract:

A testing apparatus for determining the enhanced vision capabilities of a system that is designed to assist a pilot in detecting lights and ground features in night and low visibility conditions. One embodiment of the apparatus is suitable for laboratory or production facilities, the other embodiment is used for the flight line by installing it in the aircraft. A simulated pattern is presented by the apparatus wherein the enhanced vision system (EVS) can be calibrated. Further, fog can also be simulated over the spectral band of the EVS. Runway landing lights are also able to be simulated using a readily available light source.

International Classification:

H01L 31/00

US Classification:

250332

Abstract:

An aviation vision apparatus. Its purpose assists a pilot's ability to fly an aircraft by providing increased visibility. The apparatus features an uncooled IR sensor for vision enhancement. An integrated window assembly is provided which permits the sensor to obtain its imagery. The apparatus also has an integrated aerodynamic enclosure. The apparatus features electronics responsible for window assembly window control functions and IR sensor control. The apparatus is a single line replaceable unit that receives control commands from the aircraft's head-down display or other control modules. The unit also provides for the video display.

International Classification:

A61B 3/14

US Classification:

351208, 351205, 351246

Abstract:

An apparatus and method by which an image is projected to pupils of a viewer. Preferably, the image covers only areas occupied by the pupils and tracks the areas occupied by the pupils such as to provide continuous display of the imagery to a viewer. The method is to dynamically control the direction of light into sub-apertures selected by a tracking device. By imaging selectively into the sub-apertures where the pupils are temporally located instead of imaging into a generally large area, the disclosed apparatus is power efficient and exclusive because the projected images are covert. This method is applicable to most biocular displays, for instance, but not limited to “see through” systems, which overlay imagery over real world scenes and where geometrically precise projection is critical. In one embodiment, the pupil scan apparatus is combined with a retinal scan apparatus to provide security. In this manner, only an authorized user of the apparatus can operate it.

International Classification:

G02B 27/01
G03B 21/28

US Classification:

359630, 353 98, 353 81, 353 99, 359900

Abstract:

In accordance with one embodiment of the present disclosure, a system comprises a projection system. The system further includes an image generator disposed in the projection system. The image generator is operable to generate a plurality of rays. The system further includes an objective lens disposed in the projection system. The objective lens is operable to refract the plurality of rays. The system further includes a component operable to reflect the refracted rays onto a target in order to form an image. The image is operable to be moved in relation to the target. The movement of the image is independent of any displacement of the projection system in relation to the target.

Elbit Systems of America, LLC - Fort Worth TX

International Classification:

G02B 27/01
G02B 27/28

US Classification:

353 20, 35948908

Abstract:

In accordance with one embodiment of the present disclosure, a system may include a polarizing beamsplitter for splitting one or more unpolarized rays received from an illumination source into a first polarized component and a second polarized component, the first polarized component and the second polarized component having orthogonal polarizations to each other. The system may also include a half-wave plate for rotating the second polarized component to the same polarization as the first polarized component. The system may further include a lens group for passing the first polarized component to a target plane as a first polarized ray, and further for separately passing the second polarized component to the target plane as a second polarized ray.
