Appl. No.:

09/561536

Assignee:

Sarnoff Corporation - Princeton NJ

International Classification:

H01J 2972

US Classification:

313433, 313427, 313432, 313439

Abstract:

A cathode ray tube includes an electron gun directing electrons away from a faceplate having an electrode biased at screen potential. A plurality of electrodes located on or near the rear wall of the tube envelope are biased at graduated potentials so that the electron beam is deflected by the electrostatic field produced thereby to impinge upon the faceplate. The electron beam is magnetically deflected over a relatively small angle as it exits the electron gun to scan across the faceplate to impinge upon phosphors thereon to produce light depicting an image or information. The electrodes may be biased at or below screen potential, with the electrode closest the electron gun typically biased at a negative or ground potential and the electrode closest the faceplate (i. e. distal the electron gun) typically biased below screen potential to direct electrons towards the faceplate, thereby to increase the landing angle thereof.

International Classification:

H01J 2970

US Classification:

313440, 335210, 335213

Abstract:

A cathode ray tube deflection yoke is provided wherein the deflection yoke includes a plurality of deflection coils. One or more of the deflection coils have a non-constant distribution of turns, whereby an electron beam passing through the deflection yoke is deflected by a magnetic field that varies according to different numbers of turns relative to position of electrons of the electron beam between the entrance and exit of the deflection yoke. The non-constant turns distribution may be linear or non-linear, may be monotonic or non-monotonic, and/or may have a positive or negative turns bias, either in whole or in part. The horizontal deflection coil and/or the vertical deflection coil, or both, may have a non-constant turns distribution.

Abstract:

The present invention provides a collision avoidance apparatus and method employing stereo vision applications for adaptive vehicular control. The stereo vision applications are comprised of a road detection function and a vehicle detection and tracking function. The road detection function makes use of three-dimensional point data, computed from stereo image data, to locate the road surface ahead of a host vehicle. Information gathered by the road detection function is used to guide the vehicle detection and tracking function, which provides lead motion data to a vehicular control system of the collision avoidance apparatus. Similar to the road detection function, stereo image data is used by the vehicle detection and tracking function to determine the depth of image scene features, thereby providing a robust means for identifying potential lead vehicles in a headway direction of the host vehicle.

US Classification:

313422

Abstract:

An evacuated envelope is divided into a plurality of electron propagation channels. Each channel includes an electron gun section and a beam guide section. The electron gun section provides electrons in the form of beams to the guide section. The guide section includes spaced guide meshes and the electrons are propagated along the channel in the space between the guide meshes. A launch section, in the form of at least one pair of launch electrodes, is arranged between the electron gun section and the beam guide section. The conditions under which electrons leave the gun section and enter the guide section are selected by the application of selected voltages to the launch electrodes.
