Boyd B Bushman: Object locator. Lockheed Corporation, James E Bradley, September 19, 1995: US05452089 (38 worldwide citation)

A search light employs variable polarization angles to enhance target identification. The search light shines a beam of light which may be directed across terrain. The beam of light is alternated in polarization angles at a rate of about five to twelve cycles per second. The alternating contrast in ...

Boyd B Bushman: Towed target. Lockheed Corporation, James E Bradley, March 5, 1996: US05497156 (15 worldwide citation)

A towed target or decoy serves to avoid heat-seeking and radar missile attacks on a jet aircraft. The decoy has a body with a nose and a sidewall. A ring surrounds the body and the spaced from it. The interior of the ring and the exterior of the body have reflective surfaces. The reflective surfaces ...

Boyd B Bushman: Object detection system. Lockheed Corporation, James E Bradley, Charles E Schurman, November 23, 1993: US05264916 (14 worldwide citation)

A device will detect man-made objects by using a polarizer. The polarizer rotates about an axis in front of a lens array. The rotation of the polarizer alternately polarizes light received in proportion to the speed of rotation. This produces flashing in intensity for detecting the object as well as ...

Boyd B Bushman: Object detection system. Lockheed Corporation, James E Bradley, July 4, 1995: US05430448 (10 worldwide citation)

A detection system will detect and identify self-propelled objects, such as missiles, which create a hot exhaust plume. The exhaust plume has radiation which flickers with a frequency range of interest. This frequency range can be detected with various detectors, such as an ultraviolet detector or r ...

Boyd B Bushman: Object detector. Lockheed Corporation, James E Bradley, April 4, 1995: US05404225 (9 worldwide citation)

A device will assist in detecting man-made objects by using a liquid crystal retarder and a stationary polarizer. The liquid crystal retarder shifts impinging light 90 degrees between a nonrotated and a rotated mode. In the nonrotated mode, the retarder is essentially transparent, with the light pas ...

Boyd B Bushman: Object discriminator. Lockheed Corporation, James E Bradley, September 6, 1994: US05345308 (7 worldwide citation)

A device will detect man-made objects by using a polarizer mounted to a video camera. The polarizer rotates about an axis in front of a lens array of the video camera. The rotation of the polarizer alternately polarizes light received in proportion to the speed of rotation. This produces flashing in ...
