    This article describes a method of detecting errors in a space switch arising from faults in one or more input or output lines. In the disclosed technique, knowledge of the permutation function performed by the switch is not required. A space switch is a device that maps an input binary n-tuple to an output binary...

    This article describes a technique for operating a personal computer (PC) network at lower than usual power levels, while avoiding intermodulation distortion characteristically expected for such operation. The latter result is achieved by insertion of filters in reception and transmission paths between each network...

    A method has been developed for curtailing the dip which occurs in wide open areas of semiconductor devices during fully recessed oxide isolation planarization. The new approach uses a re-flow glass as the planarization fill material and a mask to remove excess material so planarization can take place in a short...

    Personal computers contain a Basic Input Output System (BIOS) which provides routines to service the computer hardware. Access to this support is through documented interfaces structured within software interrupt routines, and such routines are placed in Read-Only Memory (ROM). The routines are designed to support...

    Image data generally originates at a camera or an array of sensors. Image data can also originate from computer simulations. The demand for storage, processing and transmission of image data is increasing very rapidly. High performance and/or special processors are built to process image data, but the high data rates...

    A technique is described whereby a 3-1/2-inch diameter magnetic disk drive mechanism may be installed in a position provided for a 5-1/4- inch diameter magnetic disk drive mechanism, through the use of an interface assembly and a circuit adapter card. The interface assembly consists of a tray assembly, with a pair of...

    This publication describes a technique to improve the electromigration life-time by reducing extrusion-shorts in fine line interconnects and electrical opens on anode contact pads. In the Al-Cu fine line interconnects, electromigration-induced failure mainly comes from void-opens because it occurs at an earlier time...

    This article describes a technique which conserves microcomputer power by using special low power consumption modes of operation when the computer system is inactive. This is accomplished by inclusion of plural "sleep modes" wherein the system clock is either stopped or operated at a reduced rate, provision of system...

    Ablative photodecomposition (APD) is the rapid photodecomposition and etching of a material by the irradiation of the material with far ultraviolet (UV) light, via an effect which is not purely thermal and in which adverse thermal effects are not produced. Application of APD as a technology for the dry etching of...

    A technique is described whereby a bridge assembly provides a support frame for mounting electromagnetic devices, such as fixed disk or floppy disk drive units. The bridge assembly is unique in that the drive units are bridged over a planar circuit board in such a way so as to allow simplified installation and...
