An apparatus provides storage for cable slack and also provides for segregation of interface cables on the front of a chassis and for segregation of intrasystem cables on the back of the chassis. A and B copies of intrasystem cables are segregated on opposite sides of the chassis. Cable slack spools are provided at the top and bottom, on each side of the front and rear surfaces. This configuration allows for convenient cable slack storage for both top-entry and bottom-entry cables.

A method and apparatus that couple a change input scan chain test pattern with an initialization scan chain test pattern such that a resultant scan chain test pattern is produced, and apply the resultant scan chain test pattern to at least one combinational logic path. In one embodiment, the coupling is achieved by interleaving the change input scan chain test pattern with the initialization scan chain test pattern. In another embodiment, the coupling is achieved by creating a constructed test p...

A method and system for use in wafer fabrication systems. The method and system capture an evolving wafer fabrication system by mapping at least one interaction between a selected at least one integral part associated with the wafer fabrication system and at least one other integral part associated with the wafer fabrication system.

An EMI cable passthrough shield for a cable opening in an electronic system housing. The EMI cable passthrough shield includes portions made of an electrically conductive, deformable material having cable passageways to receive cable. A plurality of shields can be stacked in a cable opening of an electronic system housing. The shields can be compressed such that the deformable material completely encloses a cable. An example of a deformable electrically conductive material is an electrically con...

An automatic and parameterized compute implemented method for transposing wires in an integrated circuit design can y bus lines with similar impedances, and therefore similar signal transmission characteristics. Using a specially designed CAD tool, a user can specify a transposing porn, intervals at which to transpose wires, and a metal layer through which to accomplish the transposing in the integrated circuit. Using a routing database the tool then automatically determines the locations in the...

Described herein is an apparatus for producing three-dimensional staic or moving images. In one embodiment, the apparatus includes an image generator and an optical device. The image generator generates a plurality of image elements including first and second image elements. In one embodiment the image elements constitute coherent beams of light encoded with image information, wherein the coherent beams of light are sequentially generated by one or more laser scanners of the image generator. The...

A memory system having a main memory which is coupled to a plurality of parallel virtual access channels. Each of the virtual access channels provides a set of memory access resources for controlling the main memory. These memory access resources include cache resources (including cache chaining), burst mode operation control and precharge operation control. A plurality of the virtual access channels are cacheable virtual access channels, each of which includes a channel row cache memory for sto...

Guided self-help is facilitated through use of so-called "active content" pages that are selectively viewable by given "audiences" within a technical support chain automation system. Active content is Web-based content (e.g., content viewable by a Web browser) that has one or more diagnostic maps initiated when certain actions are taken According to the invention, users are assigned to a hierarchy of audiences. A given audience within the hierarchy has the right to view active content written fo...

An apparatus, method, communications device and computer readable medium for phase aligning two clocks and providing a graceful switch between active and standby circuitry is disclosed. A reporting circuit receives a measured phase difference between a first clock signal and a second clock signal, a selection circuit selects a configurable phase adjustment according to the measured phase difference, and a granularity adjustment circuit adds the configurable phase adjustment to the first clock si...

In a telephone system having multiple working metallic interface units, a method and a structure provide protection by assigning to each metallic interface unit a partner unit, which is another metallic interface unit. Under this arrangement, when a failure occurs in a working metallic interface unit, its partner unit switches the ring/tip input signals of the failed metallic interface unit to a protection bus. A standby or protective unit then takes over by receiving the rerouted tip/ring signa...
