    This article describes a combination heatsink and shield for printed circuit (PC) card assemblies with cryptographic functions which improves the transfer of heat to the ambient of any shielded multilayer assembly. PC card designers receive frequent requests to incorporate cryptographic capabilities into their card...

    In the Hebrew alphabet there are five consonants which have two shapes. A regular shape is most often used, however, at a word end the second, or terminal, shape is used. To enable efficient operation of a keyboard, it is desirable that the keyboard operator not have to select the particular shape but, rather, the...

    A method is described which improves productivity by formatting the Virtual Resource Manager (VRM) system control blocks and provides a control block display without having to disclose the internal formats of the blocks. The VRM Debugger program contains a control block formatter. The formatter formats VRM system...

    This article describes a second level cache (L2) in a storage hierarchy which utilizes a relatively simple directory, which is managed in a way different from that of the first level cache (Ll). Both the first and second level caches are private to each CPU in a multiprocessor (MP) to avoid CPU contention for either...

    A method is described to provide a user interface to coded test cases written to test Virtual Resource Manager (VRM) function interfaces. In accordance with the new method, a set of user-interface routines is made available to testers, so that they can better control the execution of their test cases coded in PL.8...

    The instantaneous power going into a resistive ribbon is measured when used to control the average power to a desired level by a pulse-width modulation technique. The instantaneous power into the printing part of a resistive ribbon for each electrode is the product of the voltage across the printing part of the ribbon...

    A control unit simulator (CUS) tests channel functions in IBM System/ 370 processors in an automated test environment. The CUS works in the following manner. The CUS is a mode-controlled test device which operates in any S/370 channel. A six-card simulator contains the necessary logic to simulate an input/output...

    The world of document processing may be said to be divided into two general camps: 1. Those that believe the creator of a document should be able to see exactly how the document will look when it is finally printed, sometimes known as the "What You See Is What You Get" (or WYSIWYG) concept. 2. ...

    The article describes a technique (called Short Order Poll) that allows a station on a local area network (LAN) to determine the identity of the next active upstream neighbor (NAUN). The technique requires a short-order poll request MAC frame and a short-order poll response MAC frame. The technique can be used by...

    The CECL (cascode emitter coupled logic) network described in this article can be used to increase the density of more complicated logic functions, in gate arrays or custom designs. In the conventional CECL gate shown in Fig. 1, one current path always exists in the logic tree, which reaches one of the two logic tree...
