  • Exhaust device with noise suppression system
    Patent number: 11319847
    Abstract: An exhaust device includes a housing, first and second pipes, and a spacer. The first and second pipes are at least partially disposed within the housing. The first and second pipes include respective first and second surfaces. A portion of the second pipe is disposed inside the first pipe. The first and second surfaces cooperate to define an annular volume into which the spacer is disposed to prevent direct communication between the first and second pipes. One of the first and second pipes is fluidly connected to an exhaust gas inlet. The other of the first and second pipes is fluidly connected to an exhaust gas outlet. One of the first and second surfaces defines a radial indentation. The other of the first and second surfaces defines a radial protrusion. The spacer is disposed at least partially within the radial indentation and is in direct communication with the radial protrusion.
    Type: Grant

  • Wye winding radial air-core gauge system
    Patent number: 5004976
    Abstract: A wye-type air-core gauge system provides magnitude indications of measurands in response to PWM signals generated by a control unit that receives electrical signals from a sensor that represents magnitude variations of the measurand. The size of the stator coils of the gauge makes possible a very low profile gauge suitable for mounting in an instrument cluster.
