6711418, Mar 23, 2004

Filed:

Oct 13, 1995

Appl. No.:

08/543101

Inventors:

Weijia Wang - Sunnyvale CA
Nhan Tri Nguyen - San Jose CA

Assignee:

General Wireless Communications Inc. - Santa Clara CA

International Classification:

H04Q 700

US Classification:

4555531, 4555561, 455466

Abstract:

A wireless personal mobile terminal in a cellular data network includes a packet radio transceiver for communicating with cellular base stations and a paging receiver for receiving paging signals from a paging transmitter serving a large geographical area. The wireless personal mobile message unit has power-saving features built into the signal format. This personal mobile message unit accommodates many communication applications due to the high bandwidth and the low latency achieved in the cellular data network. Low-power operation and wide coverage is achieved using existing one-way paging infrastructure. The wireless personal mobile unit can be achieved inexpensively by modifying a conventional one-way pager.

International Classification:

G06Q 30/00

US Classification:

705014000

Abstract:

Methods and systems for utilizing promotion data accessible via a mobile device are disclosed. A digital record of promotion data from a product provider may be stored in a database. A plurality of such digital records may be aggregated for one or more providers. A digital record may be associated with an incentive account associated with an individual. An electronic request to apply promotion data associated with the individual to a transaction and authentication data identifying the individual may be received. A digital record associated with the individual's incentive account may be located and transmitted to a transaction processing system. A processing result record associated with the digital record may be received from the processing system. Usage information derived from the processing result record may be associated in a database.

International Classification:

G06Q 40/06

US Classification:

705 36 R

Abstract:

A method comprising creating and storing a graph having nodes and edges that represent financial assets and accounts in which the assets are held; individuals who own the assets; or legal entities who own the assets; receiving and storing bucketing factors and column factors; traversing the graph and creating a list of a plurality of paths of nodes and edges in the graph; applying the bucketing factors to the paths to result in associating each set among a plurality of sets of the nodes with a different value node among a plurality of value nodes; applying the column factors to the paths and the value nodes to result in associating column result values with the value nodes; creating and causing displaying a table view by forming rows based on the value nodes and forming columns based on the column result values.

Assignee:

Zeneca Limited - London

International Classification:

A01N 4354
C07D23926

US Classification:

504239

Abstract:

Herbicidal substituted hydroxybenzyl-heteroaryl compounds and derivatives thereof of the formula ##STR1## wherein Ar is a substituted or unsubstituted 5- or 6-membered heteroaryl group having 2 or 3 ring nitrogen atoms or a substituted or unsubstituted 5-membered heteroaryl group having two ring heteroatoms, one of the ring heteroatoms being nitrogen and the other being sulfur or oxygen.
