Filed:

Jun 5, 2001

Appl. No.:

09/874570

Inventors:

Gregory Scharosch - Everett WA, US
Kurt Swanson - Redmond WA, US

Assignee:

AT&T Wireless Services, Inc. - Redmond WA

International Classification:

H04Q 720
G06F 1750
G06G 762

US Classification:

703 13, 703 1, 703 5, 455446

Abstract:

A method of determining RF coverage area in a point-to-multi-point RF transmission system and creating model maps showing serviceable business addresses within a given region. The method includes selecting a standard design signal strength level required to provide suitable service; obtaining field measurements of received signal strength from base stations at various points in the region under investigation; creating a model map of received signal strength having a signal strength level greater than the system standard signal strength level and excluding areas whose field strength measurements do not indicate suitable service; and creating a model map having a signal strength level smaller than the system standard signal strength level. The method is capable of providing more than 90% accuracy, and prevents needless dispatching of installation crews to a customer premise that is outside the effective RF coverage of the system.

Appl. No.:

7/528390

Inventors:

Kurt W. Swanson - Kent WA

Assignee:

General Dynamics Corporation, Convair Division - San Diego CA

International Classification:

F16B 1304
F16B 3902

US Classification:

411 19

Abstract:

The fastening together of structural elements formed from carbon-carbon is accomplished by a fastener constructed from 2-D or 3-D carbon-carbon in the form of a high angle helical threads on one end and a countersunk head with a carbon-carbon central insert on the other end with the threaded end inserted through the carbon-carbon structural elements to be joined. A metal is painted on the threads and the shank on the fastener. A collar formed from carbon-carbon is fitted over the course threaded end of the fastener with the distal end of the threads extending therefrom. While passing a heating current through the fastener, the head and the collar of the fastener are forced together. The fastener is heated to an elevated temperature in the presence of an Oxygen gas cover which causes the powered metal to expand up to 100% binding the fastener to the carbon-carbon components, collar and insert.

Appl. No.:

7/528409

Inventors:

Kurt W. Swanson - Kent WA

Assignee:

General Dynamics Corporation, Convair Division - San Diego CA

International Classification:

F16B 1304

US Classification:

411 19

Abstract:

A method for joining carbon-carbon structural elements together using a carbon-carbon pin type fastener for transfer of shear loads. A coating of powdered metal which undergoes a large expansion when reacted in the presence of a gas is used to coat the outer surfaces of a pin which extends through the structural elements to be joined, with the powdered metal coating between the body of the pin and the surfaces of the structural elements through which the pin passes. After installation through the structural elements the pin is heated in an oxygen atmosphere causing the powdered metal coating to expand up to 100% from its unheated volume binding the pin to the structural elements. A fluted or scalloped edge on the pin increases the surface area of the pin increasing its friction holding force.

Appl. No.:

8/414631

Inventors:

Assignee:

Ocean Spar Technologies, LLC - Bainbridge Island WA

International Classification:

A01K 7100

US Classification:

119223

Abstract:

Anchorable mobile pens for growing fish or shellfish that have an elongate central vertical spar buoy surrounded by at least one horizontal net-supporting ring with continuous netting extending from an upper end of the buoy to the ring and thence to a lower, submerged end of the buoy to produce an enclosed pen. The pen is optionally not anchored and free to float with the currents although it may more often be anchored by conventional means. The mobility of the pens provides the benefits of avoidance of localized hazards, like toxic plankton blooms, and the capability to move the pen to a more convenient fish-harvesting location, if necessary.

Filed:

Appl. No.:

7/255676

Inventors:

Kurt W. Swanson - Kent WA

Assignee:

General Dynamics Corporation, Convair Division - San Diego CA

International Classification:

F16C 900

US Classification:

403 30

Abstract:

A fastener for connecting structures having significantly different coefficients of thermal expansion (CTE) which substantially eliminates thermal stress with varying ambient temperatures, while allowing said structures to be either abutting or spaced from each other. A frusto-conical bore through a wall of a first structure receives a frusto-conical surface of an elongated fastener which is coincident with said bore. The fastener has a base secured to a second structure. A shoulder is formed on the first structure around the narrow end of the bore, the shoulder having a frusto-conical outer edge. A flange member is secured to the vertex end of said fastener, the flange member having a surface configured to engage the outer edge in a coincident relationship. The fastener is tightened to bring both pairs of coincident conical surfaces into pressure contact. Both parts of conic surface preferably have a common vertex which lies outside the fastener.
