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.
Apparatus And Method For Unity Gain Buffer With High Switching Speed And Low Quiescent Current

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.

International Classification:
G06F 1/16 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.

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.
