20020111181, Aug 15, 2002

Filed:

Feb 12, 2002

Appl. No.:

10/076014

Inventors:

Brent Jaybush - Los Angeles CA, US
Han Lee - Cypress CA, US
Hong Lim - Rosemead CA, US

International Classification:

H04B007/00

US Classification:

455/519000, 455/517000

Abstract:

A radio dispatch system has a plurality of base stations covering a large geographic area. The base stations are connected to the Internet so voice messages can be sent between them. Each of a plurality of mobile transceivers is adapted to send voice messages to one of the base stations and receive voice messages from one of the base stations. As a result, the mobile transceivers can communicate with each other and the base stations over a wide geographic area limited only by the reach of the Internet.

US Patent:

Filed:

Dec 17, 1990

Appl. No.:

7/628823

Inventors:

Hong S. Lim - Agoura Hills CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

H01M 1000

US Classification:

320 2

Abstract:

Excess electrolyte fluid from a nickel cadmium battery cell is removed by a method in which the battery cells are overcharged to generate oxygen pressure which acts to force the excess fluid out of the cells. After the required amount of fluid is removed from the battery, the generated oxygen may be replaced to ensure proper operation of the finished battery.

International Classification:

B05D 300
B05D 118
B05D 302
H01M 216

US Classification:

427352

Abstract:

Chemically stable polymers in aqueous alkaline solutions are dissolved in a strongly polar solvent, thoroughly dispersed from this solvent into and throughout the interstices of porous inorganic fabrics and subsequently separated from said solvent by precipitation to provide a homogeneous reinforcement of the structural properties of said fabrics.

Filed:

Mar 12, 1984

Appl. No.:

6/588620

Inventors:

Hong S. Lim - Agoura CA

Assignee:

Hughes Aircraft Company - El Sequndo CA

International Classification:

H01M 1036

US Classification:

429 59

Abstract:

A nickel-hydrogen bipolar battery comprises a plurality of unit cells organized in assemblies wherein the assemblies are stacked and positioned within a hydrogen space. Each unit cell includes a porous hydrogen electrode loaded on its lower surface with a platinum catalyst layer. Adjacent the platinum loaded lower surface of the porous hydrogen electrode lies a separator. A nickel electrode lies against the separator opposite the surface adjacent to the platinum loaded surface. One or more openings through the nickel electrode and separator cooperate to permit oxygen gas, generated at the nickel electrode, to reach to the hydrogen electrode of the same unit cell. Recombination of hydrogen gas and oxygen gas occurs at the hydrogen electrode platinum catalyst layer. The assembly provides serial connection of the unit cells through conductive end plates for axial current flow through the assembly stack.

Inventors:

Hong Sup Lim - Agoura CA

Assignee:

Hughes Aircraft Company - Culver City CA

International Classification:

C09K 334
G02F 113

US Classification:

252299

Abstract:

Metallocenes when mixed with conjugated cyano-organic compounds such as 7,7'8,8'-tetracyanoquinodimethane (TCNQ) and (2,4,7,-trinitro-9-fluorenylidene)-malononitrile (TFM) function as excellent dopants for liquid crystals.

Filed:

Jun 6, 1995

Appl. No.:

8/470551

Inventors:

Hong S. Lim - Agoura Hills CA

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

H01M 404
H01M 452

US Classification:

296235

Abstract:

A nickel electrode having a lightweight porous nickel substrate is subjected to a formation cycle involving heavy overcharging and under-discharging in a KOH electrolyte having a concentration of 26% to 31%, resulting in electrodes displaying high active material utilization.

Appl. No.:

5/839224

Inventors:

Hong S. Lim - Agoura CA
Michael J. Little - Tarzana CA

Assignee:

Hughes Aircraft Company - Culver City CA

International Classification:

G02F 113
C09K 334

US Classification:

350336

Abstract:

Reflective mode dynamic scattering displays are disclosed which operate under dc excitation for extremely long hours with excellent contrast. These displays are the results of a combination of a high reflectivity cathode, obtained by the use of silver mirror electrodes, with a redox doped ester liquid crystal in an otherwise conventional liquid crystal cell arrangement.

Assignee:

Hughes Aircraft Company - Los Angeles CA

International Classification:

H01M 1044
