Filed:

Apr 11, 2001

Appl. No.:

09/833528

Inventors:

Jing W. Jiang - San Jose CA, US
Xiaojun Fang - Hayward CA, US
Robert J. Deri - Pleasanton CA, US
Lawrence J. Pelz - Livermore CA, US

Assignee:

Terawave Communications, Inc. - Hayward CA

International Classification:

H04J 3/06

US Classification:

370465, 370509

Abstract:

A technique for communicating a change in bit rates that dependent transponders should each transfer. In one implementation, an upstream transponder outputs a specific frequency communications signal to a downstream transponders. The downstream transponder reacts to receipt of the specific bit rate by requesting new bit rate window information. The upstream transponder communicates such new bit rate window. Thereafter both the upstream and downstream transponders transfer payloads of signals having bit rates within the programmed bit rate windows.

International Classification:

G06F 17/50

US Classification:

716 5, 716 4

Abstract:

A method and system for formally verifying designs having elements from more than a single design domain is described. An example system allows formal verification of a design containing mixed analog and digital subparts. The system may use different proof engines to solve an appropriate sub-partition of the entire design, and may provide a framework for translating between the different domains to create a unified result. For example, a digital proof engine may be used for a digital only subpart, while an analog proof engine may be used for an analog only subpart. The system may use the partitioning results to determine translators between the various domains, and an order in which the proof engines are applied.

International Classification:

G06F 17/50

US Classification:

716 5, 716 11

Abstract:

A method and system for performing consistency checking of one or more design representations having different design types. A translator for each design type obtains information from each design needed to evaluate rules that are design type-neutral. The described examples also allow a user to add rules using predefined rule terms. In addition, certain examples allow the user to add terms to the rule set and to make new rules with the added terms. Each new term added to a rule set has a corresponding abstraction function in a translator for each design type. Thus, the abstraction functions are not design type-neutral.

Appl. No.:

11/581502

Inventors:

James Li - Santa Clara CA, US
Jing Jiang - San Jose CA, US

Assignee:

Marvell World Trade Ltd. - St. Michael

International Classification:

H01Q 1/24

US Classification:

343702, 343700 MS

Abstract:

An antenna system comprises first, second, and third antennas that are arranged on a printed circuit board (PCB) and that include an arc-shaped element having a concave side and a convex side. A conducting element extends substantially radially from a center of the concave side. A U-shaped element has a base portion with a center that communicates with the conducting element and two side portions that extend from ends of the base portion towards the concave side.
