  • Integrated hazard avoidance system
    Patent number: 6127944
    Abstract: A hazard alert device for aircraft prioritizes various alerts according to predefined criteria. The device enables more optional alerting of hazardous conditions than a system of separate independent and discrete devices.
    Type: Grant
    Filed: April 20, 1999
    Date of Patent: October 3, 2000
    Assignee: Allied Signal Inc.
    Inventors: Francis W. Daly, Daryal Kuntman, Frank Doerenberg, James J. McElroy
  • Fault tolerant data bus
    Patent number: 6052753
    Abstract: A fault tolerant bus architecture and protocol for use in applications wherein data must be handled with a high degree of integrity and in a fault tolerant manner. As applied to an integrated flight hazard avoidance system, the system is constructed of two or more microprocessor-driven modules that generate data, two independent bus interface controllers per module, and an inter-module backplane data bus that links each module. The system allows comparison of identical data from multiple sources. If invalid data is detected, the system either passes the correct data copy or generates a system fault message. The bus architecture utilizes a distributed synchronization protocol, and does not require a master synchronization source.
