  • Patent number: 6253540
    Abstract: An infrared suppressor system for a gas turbine engine is provided for suppressing infrared radiation associated with the hot metal parts of the engine and with the hot exhaust gases exhausted from the engine. The system features a unique arrangement of multiple baffles that are connected together as a single baffle module. The baffle arrangement permits mixing of hot and cool gas flows while eliminating line-of-sight infrared radiation in an axially compact suppressor. The baffles are additionally linked together into a single insertable baffle module that permits removal of the baffle module when infrared suppression is unnecessary.

  • Patent number: 5107491
    Abstract: There is disclosed a collision filter for use in a network to detect a fault condition wherein two or more nodes are simultaneously transmitting on the network. The fault condition is characterized by an increased average DC voltage level on the network. The collision filter includes a low pass filter stage having an input coupled to the network and an output and a notch filter having an input coupled to the low pass filter stage output. The notch filter has at least one attenuation notch at a desired frequency and an output for providing the increased average DC voltage level responsive to a fault condition.

  • Patent number: 5012384
    Abstract: There is disclosed an improved output circuit for use with a differential line driver which drives a parallel inductance and resistance load coupled across the line driver output. The output circuit substantially reduces the kickback voltage produced across the load which results from a residual magnetizing current being stored in the load inductance. The output circuit includes an impedance means which is coupled across the output terminals and a common mode current source coupled between the impedance means and a common potential for sinking a portion of the residual magnetizing current to reduce the amount of residual magnetizing current flowing through the load resistance.

  • Patent number: 4002024
    Abstract: An infrared suppression system is provided for an aircraft gas turbine engine for reducing the level of emitted infrared radiation from the engine exhaust. The hot exhaust stream emitted from the engine is mixed with the cooling airflows received from a plurality of sources in order to more effectively reduce the level of emitted infrared radiation. In addition, the infrared suppression system prohibits a direct line of sight back into the core engine.
