    摘要: A fault-tolerant computer system provides information transfers between the units of a computing module, including a processor unit and a memory unit and one or more peripheral control units, on a bus structure common to all the units. Information-handling parts of the system, both in the bus structure and in each unit, can have a duplicate partner. Error detectors check the operation of the bus structure and of each system unit to provide information transfers only on fault-free bus conductors and between fault-free units. The computer system can operate in this manner essentially without interruption in the event of faults by using only fault-free conductors and functional units.Arbitration circuits of unusual speed and simplicity provide units of the computing module with access to the common bus structure according to the priority of each unit.The units of a module check incoming and outgoing signals for errors, signal other module units of a detected error, and disable the unit from sending potentially erroneous information onto the bus structure.

    摘要: Electronic apparatus and method for determining location of the sensing aperture of a light pen on the face of a raster scan monochrome CRT is disclosed. In a preferred embodiment, logic circuitry and cascaded counters are used to determine position information for the earliest horizontal detection of light during each frame. Apparatus is included for retaining the position information and making it available to the CRT processor for use in generating a cursor.

    摘要: Electronic apparatus and method is disclosed for generating a linearity correction signal for use in or with a CRT electron beam deflection circuit. In a preferred embodiment, transistor is used to vary the parameters of a multiple feedback infinite gain bandpass filter such that the filter is essentially on the point of oscillation during trace, but is highly damped during retrace.

    摘要: A multinodal system is one-way interconnected, two-way interconnected or, more generally, (n)-way interconnected, where (n) is an integer. In a one-way interconnected system, only one connection element couples any two nodes. Or, put another way, only one communication path exists between every node and every other node. A two-way interconnected system, on the other hand, has two connection elements coupling each pair of nodes. Likewise, an (n)-way interconnected system provides (n) independent connection paths between each pair. Such systems are characteristic in that the relationship between the number of independent buses (b), the number of nodes (v), the number of ports (r), and the degree of interconnectedness (n) can be expressed by the equation ##EQU1## Two-way and (n)-way interconnect arrays may be adapted for use in fault-tolerant communications.
