  • Apparatus for minimizing the effects of laser intensity reduction at cold temperatures in ring laser gyros
    Patent number: 6108358
    Abstract: A circuit for controlling the run current in a ring laser gyro includes circuitry for sensing temperature, supplying a current to the ring laser gyro and controlling the current supplied to the ring laser gyro and the current varies depending on the temperature. The current changes at predetermined temperature points.

    Assignee: Honeywell Inc.
    Inventors: Steven C. Albers, Stephen M. Baker, Timothy J. Callaghan, Lloyd W. Priddy
  • Arinc 629 data receiver system having an interface for providing identification to each of the received data word types
    Patent number: 5864687
    Abstract: A memory interface system is operable with a ARINC 629 terminal controller for directing storage of data message received by the terminal controller into a memory device, and associating with each of the words stored in the memory device a tag word which identifies the word type being stored.

  • FIFO fail-safe bus
    Patent number: 5600786
    Abstract: The invention is an apparatus which utilizes relatively few conductors to provide fail-safe communication between multiple electrical subsystems and a redundant pair of data processors. This is accomplished by including two first-in, first-out memory units within each electrical subsystem, and utilizing these memory units to send the output data from the electrical subsystems on a pair of parallel data buses to a redundant pair of data processors, which then perform error tests on the data to ensure its integrity.

  • Data backup and recovery in a data processing system
    Patent number: 5381545
    Abstract: A data processing system for managing stored data is described. A log recording incremental updates to the data is provided for data recovery purposes in the event of a system failure. A backup copy of at least a portion of the stored data can be made without closing that portion for update. Any in-progress modifications at the time the backup is taken are allowed for by calculating a recovery point before the time of the backup, from which point recovery is to be performed using the recovery log. The recovery point depends at least in part on the start time of the oldest in-progress data file update.

    Date of Patent: January 10, 1995
    Assignee: International Business Machines Corporation
    Inventors: Stephen M. Baker, Peter J. Lupton
  • Line reel mower
    Patent number: 4653255
    Abstract: A lawnmower apparatus having a plurality of elongated lines or cables fabricated from a plastic material and the like that are arranged for movement about an axis. The lines are attached to rotatable plates or discs such that the apparatus acts as a reel-type lawnmower to cut grass in conjunction with an elongated bar. A resilient assembly maintains appropriate tensioning of the lines during operation of the lawnmower.
