International Classification:

B05D 300

US Classification:

427294

Abstract:

A low-density resin impregnated ceramic article advantageously employed as a structural ceramic ablator comprising a matrix of ceramic fibers. The fibers of the ceramic matrix are coated with an organic resin film. The organic resin can be a thermoplastic resin or a cured thermosetting resin. In one embodiment, the resin is uniformly distributed within the ceramic article. In a second embodiment, the resin is distributed so as to provide a density gradient along at least one direction of the ceramic article. The resin impregnated ceramic article is prepared by providing a matrix of ceramic fibers; immersing the matrix of ceramic fibers in a solution of a solvent and an organic resin infiltrant; and removing the solvent to form a resin film on the ceramic fibers.

US Classification:

428218

Abstract:

A low-density resin impregnated ceramic article advantageously employed as a structural ceramic ablator comprising a fired preform of ceramic fibers. The fibers of the ceramic preform are coated with an organic resin film. The organic resin can be a thermoplastic resin or a cured thermosetting resin. In one embodiment, the resin is uniformly distributed within the ceramic article. In a second embodiment, the resin is distributed so as to provide a density gradient along at least one direction of the ceramic article. The resin impregnated ceramic article is prepared by providing a fired preform of ceramic fibers; immersing the preform of ceramic fibers in a solution of a solvent and an organic resin infiltrant; and removing the solvent to form a resin film on the ceramic fibers.

Appl. No.:

8/878089

Inventors:

Sudhakar Gouravaram - Fremont CA
Huy Tran - San Jose CA

Assignee:

LSI Logic Corporation - Milpitas CA

International Classification:

G01R 3500

US Classification:

3241581

Abstract:

A multi-sided, integrated circuit die includes a plurality of read only memory (ROM) circuits, positioned only at the corners of the die, to simplify qualification testing of new package designs. During qualification testing, electrical and environmental stresses are applied to the package and die combination. The package and die are electronically evaluated at predetermined intervals to determine whether a failure has occurred during testing. When a failure occurs during testing, the package and die are diagnosed to isolate and determine the cause or source of the failure. Package design parameters are adjusted accordingly to reduce or eliminate the occurrence of the failures. An optional 12-bit counter is fabricated onto the die for each ROM circuit to exercise the ROM during qualification testing. An optional process monitor is also fabricated onto the die for each ROM circuit to determine the strength of the fabrication process and the resulting quality of circuit elements produced therefrom.

H04W 24/04
H04W 64/00
G01S 5/06

Abstract:

Systems and methods provide for improving the accuracy of a location system. The location system can capture partial phase vector data from one or more access points (APs). The location system can capture associated data associated with the partial phase vector data across multiple dimensions, such as identity data of the APs and client devices generating the partial phase vector data and frequency band data, location data, a time and date, and other data associated with the partial phase vector data. The location system can determine correlation data across the multiple dimensions using the first partial phase vector data and the associated data. The location system can a cause of the partial phase vector data based on the correlation data. The location system can perform one or more remediation actions based on the cause of the partial phase vector data.

H04W 76/15

Abstract:

Techniques are disclosed for intelligent management of multiple communications links. One communications link can be used to bring up another communications link with little or no user input. Selective enablement/disablement of one or more of the communications links is based on system needs and other criteria. Utilizing one more-secure communications link to improve security on another less-secure communications link between the same devices is also contemplated.
