Filed:

Jan 21, 1998

Appl. No.:

09/010076

Inventors:

Thomas Yat Chung Woo - Red Bank NJ

Assignee:

Lucent Technologies, Inc. - Murray Hill NJ

International Classification:

H04L 516

US Classification:

370278, 370236, 370462, 455422, 375220

Abstract:

The present invention is a method and system of half-duplex wireless communication where a premises has a base station that services a defined communication cell. The base station transmits and receives Request to Send and Clear to Send announcements to and from mobile stations to indicate that the base station can send and receive data. A plurality of mobile stations send and receive data after transmitting and receiving Clear to Send and Request to Send announcements to and from the base station based on the respective time period in which the base station has received the Clear to Send and Request to Send announcements from respective mobile stations.

International Classification:

G06F 1300

US Classification:

709206, 709219, 709223, 709329

Abstract:

A wireless multimedia messaging communications method and apparatus that permits a subscriber to a wireless telecommunications service to receive and generate multimedia messages from known wireless personal communications devices, i. e. , cellular/PCS telephones. A multimedia message may be received by the network and selectively delivered to a subscriber of the wireless service. Upon receipt of the message, the network determines an appropriate action to take with respect to the message based upon a profile of the subscriber. The subscriber is then notified by the network of the message and then delivers the message and any multimedia attachments to the message to the subscriber, according to a delivery indication sent by the subscriber to the network. Advantageously, the method allows for the conversion of messages as appropriate, i. e. , text-to-speech, text-to-fax, provides gateways to varieties of multimedia information such as that found on the Internet and provides an active messaging format wherein message templates are stored on a mobile device that interprets the active messages thereby permitting a subscriber to quickly compose a message by supplying simple, dynamic components of the message.

Appl. No.:

8/868280

International Classification:

G01N 3353

US Classification:

435 71

Abstract:

A homogeneous high throughput assay is described which screens compounds for enzyme inhibition, or receptor or other target binding. Inhibition (or binding) by the library compounds causes a change in the amount of an optically detectable label that is bound to suspendable cells or solid supports. The amounts of label bound to individual cells or solid supports are microscopically determined, and compared with the amount of label that is not bound to individual cells or solid supports. The degree of inhibition or binding is determined using this data. Confocal microscopy, and subsequent data analysis, allow the assay to be carried out without any separation step, and provide for high throughput screening of very small assay volumes using very small amounts of test compound.

Appl. No.:

9/207196

Inventors:

Thomas Yat Chung Woo - Red Bank NJ

Assignee:

Lucent Technologies Inc. - Murray Hill NJ

International Classification:

G06F 1300

US Classification:

709247

Abstract:

The amount of information that must be transmitted from an Internet server to a user's computer or workstation when the user requests an Internet object, for example, by clicking on a URL in a web browser application, is reduced using a cache-based compaction technique in which the requested object is encoded in the server using information relating to similar objects that were previously supplied to the user. Similar objects available in both a client side cache and a server side cache are selected by comparing the URL of the requested object to the URL's of stored objects. Differential encoding is performed in the server such that the server transmits to the client information indicative of the differences between the requested object and the reference (similar) objects available in the server cache. A corresponding decoding operation is performed in the client, using the encoded version and reference objects available in the client cache.
