  • Direction finding method
    Patent number: 6646601
    Abstract: Determining the angle of arrival of a signal by providing a plurality of antennae, sampling, in turn, the output from each of the antennae to obtain a set of samples, each of the samples relating to different points in time, performing a Fourier transform on the set of samples, thereby producing a sequence of spectral lines, identifying a signal impinging on the antennae from the configuration of the spectral lines, and calculating, from phase and amplitude data gathered from at least a subset of the spectral lines, the direction of arrival of the signal at the antennae.
    Type: Grant

    Date of Patent: November 11, 2003
    Assignee: DSO National Laboratories

  • Aircraft monitoring and incident management system
    Publication number: 20030071743
    Abstract: The invention comprises a monitoring and incident management system for an aircraft including an on-board system on the aircraft, an incident management center on the ground, and a redundant secure communications link between the on-board system and the incident management center. The on-board system includes components that assist the aircraft crew in identifying and defending against potential threats to the aircraft, such as suspicious passenger activity. The incident management has access to a wide variety of information concerning the aircraft and activities taking place on the aircraft, as well as the ability to transmit commands to the on-board system. The on-board system includes a cockpit door module that combines double-doors and biometric identification to prevent unauthorized access to the cockpit.
