  • Bearing health monitor
    Patent number: 8146358
    Abstract: A turbocharger monitor including a sensor adapted and positioned with respect to a turbocharger housing to sense passing compressor blades, generating both rotor rotation information and rotor displacement information. A controller is configured to receive the generated information from the blade sensor, and to establish rotor rotation speed and an indicator of bearing condition.
    Type: Grant

  • Vane control
    Patent number: 7426829
    Abstract: An exemplary controller includes a control valve that includes an electric actuator operatively coupled to a valve stem, a piston operatively coupled to one or more hydraulic fluid paths controlled by the control valve and including a piston shaft, a rotatable shaft operatively coupled to the piston shaft and mechanically isolated from the valve stem and capable of adjusting geometry of the variable geometry turbine, and an electronic sensor capable of sensing an angular position of the rotatable shaft. Various other exemplary systems, methods, devices, etc., are also disclosed.
