US Patent:

D455012, Apr 2, 2002

Filed:

Apr 9, 2001

Appl. No.:

29/139968

Inventors:

Robert Perez - Villa Park CA 92861

International Classification:

0402

US Classification:

D 4105, D4111, D4128

US Patent:

6445732, Sep 3, 2002

Filed:

Sep 23, 1998

Appl. No.:

09/159328

Inventors:

Norman J. Beamish - Costa Mesa CA
Robert K. Perez - Laguna Beach CA

Assignee:

Conexant Systems, Inc. - Newport Beach CA

International Classification:

H04B 346

US Classification:

375224, 4552261, 4552491

Abstract:

A method and apparatus which reduces the computational complexity of a receiver subject to power swings in excess of the power swings inherent in wireless communication from normal fading. To accomplish this, attenuation or some other form of signal modification occurs prior to the digital circuitry to reduce the required resolution of the analog to digital converter and other receiver components. A power signal estimator in conjunction with an attenuation control module may control the level of attenuation.

Appl. No.:

09/602173

Inventors:

Jerry Qixin Huang - Hacienda Heights CA
Robert J. Perez - Westminster CA
Leo M. DeLangis - Lomita CA

Assignee:

The Boeing Company - Seattle WA

International Classification:

G01N 2918

US Classification:

73597, 73602, 73644

Abstract:

A method for determining stiffness of a composite laminate plate entails disposing a device for generating an acoustical pulse against a surface of the plate and disposing a detecting device against the same surface spaced a known distance from the pulse-generating device, and using the pulse-generating device to emit a pulse so as to create an extensional wave in the plate. The detecting device is used to determine a time of flight of the wave over the known distance, and the wave velocity is calculated. A Youngs modulus of the plate is determined based on the wave velocity. Methods for both anisotropic and quasi-isotropic laminates are disclosed.

International Classification:

G01N029/18

US Classification:

73597, 73602, 73644

Abstract:

A method and apparatus for determining stiffness of a plate-like structure including a monolithic or composite laminate plate entails disposing a device for generating an acoustical pulse against a surface of the plate and disposing a detecting device against the same surface spaced a known distance from the pulse-generating device, and using the pulse-generating device to emit a pulse so as to create an extensional wave in the plate. The detecting device is used to determine a time of flight of the wave over the known distance, and the wave velocity is calculated. A Young's modulus of the plate is determined by a processor based on the wave velocity. Methods and apparatus for evaluating both isotropic plates and anisotropic laminates are disclosed.

US Patent:

44510934, May 29, 1984

Filed:

Mar 7, 1983

Appl. No.:

6/472630

Inventors:

Robert Perez - Santa Clara CA

International Classification:

E21C 3518
E21B 1058

US Classification:

299 88

Abstract:

Presented is a tool adapted for use in rupturing the surface of smooth concrete so as to provide a roughened surface. This process is commonly known as "scarifying" concrete. The tool comprises a bit adapted to be mounted in a conventional roto-hammer or other type actuating mechanism that provides a reciprocating and/or rotating motion, the bit being provided with a multiplicity of carbide tips which are driven repeatedly into the concrete surface to effect scarifying thereof.

International Classification:

B64G 1/58
B64G 1/14
B64C 1/40
B64C 1/12
B64C 3/26

Abstract:

A method for building an aerodynamic structure, an aerodynamic structure, and a vehicle that includes the aerodynamic structure are provided. The method includes providing a structure with at least one substantially-flat exterior surface. The method also includes attaching blocks of rigid fibrous insulation to the at least one substantially-flat outer surface of the structure. Outward-facing surfaces of the blocks of rigid fibrous insulation extend past a target outer mold line of a final aerodynamic shape. The method also includes machining the outward-facing surfaces of the attached blocks to the outer mold line.
