435 6, 435 71, 435 911, 435 912, 435 9132, 435194, 435196, 4352883, 436501, 536 231, 536 2433, 536 253

Abstract:

The presently claimed invention provides methods, compositions, and apparatus for studying nucleic acids. Specifically, the present invention provides a novel enrichment and labeling strategy for ribonucleic acids. In one embodiment, the invention provides enriching for a population of interest in a complex population by diminishing the presence of a target sequence. In a further embodiment, the invention can be used to reproducibly label and detect extremely small amounts of nucleic acids.

Appl. No.:

11/518115

Inventors:

Pantas Sutardja - Los Gatos CA, US

Assignee:

Marvell International Ltd.

International Classification:

H03D 13/00

US Classification:

327 12, 327156

Abstract:

In one embodiment, a phase detector is provided comprising a first input, a second input, and first circuitry in communication with the first and second inputs, the first circuitry operative to provide an indication of a phase difference between a first signal supplied by the first input and a second signal supplied by the second input, wherein an aberration in one of the first and second signals results in an incorrect indication of phase difference. The phase detector also comprises second circuitry in communication with the first circuitry, the second circuitry operative to provide a correct indication of phase difference despite the aberration in the at least one of the first and second signals. In another embodiment, a differential phase detector is provided.

Appl. No.:

12/139979

Inventors:

Yingxuan Li - Saratoga CA, US
Qing Yang - San Jose CA, US

Assignee:

Marvell International Ltd.

International Classification:

H04B 1/16

US Classification:

455340, 455339, 4552261, 455227

Abstract:

The following embodiments relate to an analog filter having an adjustable transfer function for use in a system or circuit that processes a signal having a changing data rate. The transfer function may be adjusted by adjusting the resistance and/or capacitance of components of the analog filter. The analog filter is calibrated based on an optimum operational parameter at a certain data rate, such as a median data rate. The analog filter may be further adjusted as the data rate of the signal changes.

Abstract:

The present disclosure provides reliable systems and methods for network notifications, i.e. Simple Network Management Protocol version 2 Protocol Data Unit (SNMPv2-Trap-PDU) messages, asynchronous notifications, InformRequest-PDU messages, and the like, between network elements, element managers, and other element managers. In an exemplary embodiment, the present invention includes a network management system and method with a plurality of network elements operating a management agent communicatively coupled to an element manager which in turn is communicatively coupled to another element manager, a network management system (NMS), an operations support system (OSS), or the like. The present invention may utilize SNMPv2 and/or v3, and includes various techniques and processes ensuring reliable notifications between any of the network elements, element managers, or the like in the network management system.
