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.

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.

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:

A61M 29/00

US Classification:

606195

Abstract:

A medical device detachment system receives an elongate delivery member, having a lumen, and an elongate core member. The system includes a housing, a user input mechanism for receiving a user input to effect detachment of a medical device, such as an embolic coil, from a distal end of the delivery member, and a grasping mechanism for grasping and moving a proximal end of the core member relative to a proximal end of the delivery member. The system also includes a first sensor detecting positioning of the proximal end of the core member within the housing, and a second sensor, detecting movement of the grasping mechanism. An indicator is connected to the first and second proximity sensors and provides feedback to a user.

Hoai Nguyen - Westminster CA, US

International Classification:

A61B 17/22
A61F 2/95
A61B 17/221

Abstract:

Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the removal device. The removal device can have a core assembly that includes a hypotube coupled to a first electrical terminal and a pushwire coupled to a second electrical terminal, the pushwire extending through the hypotube lumen. An insulating layer separates the hypotube and the pushwire, and an interventional element is coupled to a distal end of the pushwire. The interventional element can be disposed adjacent to a thrombus. An electrical signal is delivered to the interventional element to promote adhesion of the thrombus to the interventional element. The electrical signal can optionally be a periodic waveform, and the total energy delivered can be between 0.75-24,000 mJ and the peak current delivered via the electrical signal can be between 0.5-5 mA.

H04L 29/06

Abstract:

The disclosure relates to a portable computing device configured to selectably switch between a wired zero client mode in which the portable computing device operates as a terminal for a host computer via a wired communication channel, a wireless zero client mode in which the portable computing device operates as a terminal for the host computer via a wireless communication channel, and a local mode in which the portable computing device operates independently from the host computer. The portable computing device may include one or more zero client processors that facilitate operation in the wired or wireless zero client mode and one or more local control processors that facilitate operation in the local mode. The portable computing device may include input devices used to receive inputs for the host computer during the wireless or wired zero client modes or for the local control processors during the local mode.
