58501452, Dec 15, 1998

Filed:

Sep 9, 1996

Appl. No.:

8/707848

Inventors:

Gregory D. Burroughs - Sunnyvale CA
Edward G. Weaver - Sunnyvale CA
Donald L. Rogers - San Jose CA

Assignee:

Hewlett-Packard Co. - Palo Alto CA

International Classification:

G01R 3128

US Classification:

324751

Abstract:

A method and apparatus for soft error comparison testing of electronic components exposed to a flux of high energy particles, while providing for simultaneous comparison testing of different components at full rated operating speed, and providing for programmable control of level of the supply voltage applied to the components. Included a method and apparatus for simultaneously exposing electronic components to a flux of high energy particles, operating the components, and simultaneously measuring soft errors of the components induced by the flux of high energy particles.

Filed:

Aug 26, 1994

Appl. No.:

8/296779

Inventors:

Donald Z. Rogers - Santa Rosa CA

Assignee:

Deposition Sciences, Inc. - Santa Rosa CA

International Classification:

B32B 904

US Classification:

428446

Abstract:

An article useful as a gemstone or decorative object. A formed substrate is used as a base for an optical interference coating applied on the exterior of the substrate. The optical interference coating is made of alternating layers of materials with relatively high refractive indices and relatively low refractive indices, the refractive indices and thicknesses of the alternating layers being chosen so that at least part of the light of wavelengths between 400 nanometers and 700 nanometers incident on the article is reflected. The optical coating creates an interference filter formed of alternating layers of a material with a low refractive index and a material with a high refractive index. The article provides a visual appearance that is novel and different from other gemstones or decorative objects, either man-made or natural.

Appl. No.:

6/935630

Assignee:

Northrop Corporation - Hawthorne CA

International Classification:

B65G 4300

US Classification:

428260

Abstract:

A flexible electrically conducting cloth is described which comprises a plurality of intermingled or interwoven refractory fibers the sheet resistance of which exceeds 1,000 ohms per square inch and a conducting coating encapsulating a majority of the fibers, the coating including at least about 70 atomic percent carbon and being applied in sufficient quantity to render the cloth electrically conducting with a sheet resistance which lies between about 0. 1 ohm per square inch and about 1,000 ohms per suqare inch. The cloth is useful as an electrical resistance heater, an electromagnetic shield, an electromagnetic reflector, or as an antenna. It is formulated by contacted substantially the entire surfaces of the intermingled or interwoven fibers with a carbon containing precursor, the fibers being at a temperature between about 700. degree. C. and 1200. degree. C. , whereby the fibers are covered with a pyrolyzed coating formed from the precursor in an amount of at least about 0. 001 weight percent.
