Filed:

Sep 30, 2003

Appl. No.:

10/676531

Inventors:

Dinh Quoc Nguyen - San Jose CA, US

Assignee:

National Semiconductor Corporation - Santa Clara CA

International Classification:

H01L023/62
H01L029/74
H01L031/111
H02H009/00

US Classification:

257173, 257111, 257162, 257168, 257355, 257356, 257357, 257546

Abstract:

A bi-directional silicon controlled rectifier structure provides electrostatic discharge (ESD) protection against both positive and negative voltage spikes. The structure utilizes a pair of wells, n+ and p+ regions formed in both wells, a first ring formed around the junction between the first well and the semiconductor material, and a second ring formed around the junction between the second well and the semiconductor material.

Appl. No.:

12/179458

Inventors:

Chang Chia Hsiao - San Jose CA, US
Dinh Nguyen - San Jose CA, US

Assignee:

National Semiconductor Corporation - Santa Clara CA

International Classification:

H03F 3/26

US Classification:

330267, 330263

Abstract:

A unity gain buffer is provided. The unity gain buffer includes two complementary pairs of emitter followers and two bias current sources. The top bias current source is arranged to provide a bias current so that, if the input voltage is greater than zero, the bias current provided by the top current source increases at the input voltage increases. The bottom current source is arranged to provide a bias current so that, if the input voltage is less than zero, the bias current provided by the bottom current source decreases as the input voltage decreases.

G06F 1/20

US Classification:

36167908, 36167958, 36167947

Abstract:

The adaptive computing system described herein may generally include a modular control, switching, and power supply architecture. In particular, the adaptive computing system may provide a platform supporting multiple independent desktop computer modules that occupy less physical space than a standalone commercial computer, provide performance density comparable to current server solutions, and address concerns relating to stability, safety, productivity, performance, assembly, service, and other factors important to diverse desktop computer user communities. Moreover, mechanical, electrical, and functional components associated with the adaptive computing system may have various certifications or otherwise be relied upon to demonstrate compliance with criteria in regulatory, environmental, consumer safety, and other contexts.

International Classification:

A61B 17/12

Abstract:

Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, includes an occlusive device comprising a mesh having a low-profile state for intravascular delivery to the aneurysm and a deployed state, the mesh comprising a first end portion, a second end portion, and a length extending between the first and second end portions, and a first lateral edge, a second lateral edge, and a width extending between the first and second lateral edges. The mesh may have a predetermined shape in the deployed state in which (a) the mesh is curved along its width, (b) the mesh is curved along its length, and (c) the mesh has an undulating contour across at least a portion of one or both of its length or its width. The mesh is configured to be positioned within the aneurysm in the deployed state such that the mesh extends over the neck of the aneurysm.
