  • Sintered material for a magnetic track brake
    Patent number: 6364072
    Abstract: A sintered material is used as a friction material for a pole shoe area of a magnetic track brake, having at least one of a magnetic basic member and a carrier member. The sintered material contains at least one of a proportion of pulverized wear inhibitor and a proportion of powder forming a protective layer.

  • Method for determining a periodic pattern in a line spectrum
    Patent number: 5436847
    Abstract: The invention relates to a method for determining a periodic pattern in an amplitude spectrum, for example, in a Doppler spectrum of a radar echo. A residual spectrum is formed using Fuzzy Set Theory, and the periodic pattern is determined for each residual spectrum by histogramming the original spectrum. The method can be used for identifying aircraft, for example helicopters, that have periodically-moving components, e.g., rotors, that generate a periodic pattern in a Doppler spectrum.
