Filed:

Feb 18, 1997

Appl. No.:

08/802187

Inventors:

JAMES JEN-CHEI CHANG - RANDOLPH NJ, US
ALBERT CHOW - HILLSDALE NJ, US

International Classification:

H04Q007/20
H04M011/00

US Classification:

455/406000, 455/407000, 455/408000, 455/426000, 455/445000

Abstract:

Systems and methods for providing intelligent wireless access systems are presented. A microcell cellular architecture is provided in which a digital switch and controller are provided in conjunction with a number of intelligent radio ports. Each of the intelligent radio ports provides at least one voice channel to both the microcell and to the traditional wireless macrocell. Calls placed within the microcell, however, do not access the traditional public macrocell. This architecture enables the microcell to be easily integrated into an existing wire-based system such that calls placed to the wire-based system are simultaneously forwarded to a cell phone (thereby ringing at both phones using a single phone number). If the call is answered by the cell phone within the confines of the microcell (i.e., via an intelligent radio port rather than a conventional wireless base station), the call is handled as a wire-based call and the type of phone used to answer the call is transparent to the caller.

Filed:

Jun 30, 1994

Appl. No.:

8/268468

Inventors:

James J. Chang - Randolph NJ
Anil T. Kripalani - Randolph NJ
Ashok N. Rudrapatna - Basking Ridge NJ
Jesse E. Russell - Piscataway NJ

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

H04Q 738

US Classification:

379 58

Abstract:

A telephone signaling system is operative outside of the traditional calling and data transmission paths to provide originating to termination signaling. Routing of the signaling is in response to a locator system which includes a data base of terminations and a system for keeping up to date information of current termination locations of the intended recipient. In one illustrative embodiment the termination equipment includes locator devices such as GPS locating devices. The information supplied by the GPS locating device is provided to a central data base which routes the signaling system to the intended recipient termination device. The central routing system then selects a voice and data transmission path that optimizes some preselected criteria of transmission. A typical criteria could be cost, or bandwidth or some combination of criteria to be optimized.

Filed:

May 31, 1977

Appl. No.:

5/802127

Inventors:

James F. Chang - Miami FL

International Classification:

A47C 302

US Classification:

297270

Abstract:

An article of furniture that includes a curved lower outer surface so that the article of furniture or chair can be rocked back and forth, the chair including stop members for limiting rocking motion or movement of the chair, and wherein reinforced portions are provided for supporting occupants of the chair so that the occupants will not sink down too far in the chair.

Filed:

Mar 25, 1994

Appl. No.:

8/218010

Inventors:

Douglas A. Usifer - Belle Mead NJ
Melvin Brauer - East Brunswick NJ
James C. Chang - Crystal Lake IL
Yuan Chieh Chu - East Windsor NJ

Assignee:

Caschem, Inc. - Bayonne NJ

International Classification:

B32B 900

US Classification:

428457

Abstract:

An electrical component comprising an electrical component having an exterior protective layer on at least a portion of a surface. The layer is a cured copolymer of a reaction between at least one oligomer having a terminal ethylenically unsaturated group and at least one monomer having a terminal ethylenically unsaturated group. Alternatively, the layer is a cured copolymer of a reaction between at least two oligomers having a terminal ethylenically unsaturated group. The copolymerization reaction is preferably in the presence of a free radical initiator curing agent and a transition metal catalyst.
