  • Multiple memory bank parity checking system
    Patent number: 5052001
    Abstract: A ROM/PROM memory system circuit structure provides for vertical expansion of data words while providing for enablement of parity checking by the addition of a single auxiliary ROM/PROM memory chip which duplicates the type and size of data memory chips. Additionally, selection means is provided to choose either an odd parity or an even parity format.
    Type: Grant

    Date of Patent: September 24, 1991
    Assignee: Unisys Corporation
    Inventors: James H. Jeppesen, III, Bruce E. Whittaker
  • Power control network for multiple digital modules
    Patent number: 4677566
    Abstract: A power network control system has a plurality of digital modules interconnected. A master logic unit in the network communicates with a specialized protocol to slave logic units in each module. The slave logic unit can instruct a power control circuit to turn-off or turn-on various power supply modules in addition to adjusting a power module in steps of plus or minus fixed percentage amounts.

  • System control network for multiple processor modules
    Patent number: 4658353
    Abstract: A system for controlling communication in a network of digital modules where each digital module has a maintenance processor which connects the digital module through a network bus to every other digital module's maintenance processor. Each transmitting module can lock up the network bus temporarily for data transmission operations to a specifically addressed receiver module. This system basically permits free communication access of any digital module to any other digital module.

  • Power control network using reliable communications protocol
    Patent number: 4635195
    Abstract: A power network control system has a plurality of digital modules interconnected. A master logic unit in the network communicates with a specialized protocol to slave logic units in each module to provide a reliable power control system for selectively (or generally) instructing modules to turn on or to turn off the local power source.
