  • Publication number: 20170178421
    Abstract: A sensor assembly includes one or more accelerometers that generate movement signals indicative of movement of a powered system, a fluid level sensor that generates fluid level signals indicative of an amount of fluid in the powered system, and one or more processors that receive the movement signals and the fluid level signals. The one or more processors also (a) filter at least some of the movement signals based on a speed at which the powered system operates and/or (b) calculate one or more of (1) a statistical measure, (2) a fast Fourier transform (FFT), or (3) a discrete Fourier transform (DFT) of the movement signals. The assembly also includes a first antenna that wirelessly communicates the one or more of the movement signals, the amount of fluid, the statistical measure, the FFT, or the DFT to a remote location.

  • Publication number: 20170089446
    Abstract: A vehicle sensor system includes a fluid sensor configured to be disposed onboard a vehicle system and at least partially extend into a gearbox of a traction motor of the vehicle system. The fluid sensor is configured to output data representative of an amount of a lubricating fluid in the gearbox. The system also includes a positioning system configured to output data representative of movement or an absence of movement of the vehicle system, and one or more processors configured to determine the amount of the lubricating fluid in the gearbox based on the data that is output by the fluid sensor responsive to the data output by the positioning system indicating that the vehicle system has not moved or has moved by less than a designated distance for at least a designated, non-instantaneous period of time.

  • Publication number: 20170084094
    Abstract: A sensor system includes one or more sensors that sense vibrations of a vehicle and one or more processors that can determine a speed of the vehicle and determine whether the vibrations occurring at one or more frequencies of interest (that are based on the speed of the vehicle) indicate damage to a propulsion system of the vehicle. The one or more processors optionally may determine a hunting frequency of a wheel and axle set and/or a lateral acceleration of the wheel and axle set from the vibrations. The one or more processors can determine a conicity of a wheel in the wheel and axle set based on the hunting frequency and/or the lateral acceleration that is determined.

  • Publication number: 20160018381
    Abstract: System includes a sensor operably coupled to a device body. The sensor includes a sensing region and at least one resonant inductor-capacitor-resistor (LCR) circuit. The sensing region is configured to be placed in operational contact with an industrial fluid. The at least one resonant LCR circuit is configured to generate an electrical stimulus that is applied to the industrial fluid via electrodes at the sensing region. The device body includes one or more processors configured to receive an electrical signal from the sensor that is representative of a resonant impedance spectral response of the sensing region in operational contact with the industrial fluid responsive to the electrical stimulus. The one or more processors are further configured to analyze the resonant impedance spectral response and determine both a water concentration in the industrial fluid and an aging level of the industrial fluid based on the resonant impedance spectral response.

  • Patent number: 8684150
    Abstract: A control assembly includes a monitoring module and a switching module. The monitoring module determines a load demand of a first rail vehicle traveling along a track, wherein the first rail vehicle is supplied with electric current from a plurality of power sources over a conductive pathway extending along the track. The switching module is communicatively coupled with the monitoring module and is joined with a switch controller disposed between the power sources and the conductive pathway. The switching module directs the switch controller to change which of the power sources supply the electric current to the first rail vehicle over the conductive pathway based on the load demand.

  • Patent number: 8468952
    Abstract: Methods and system are provided for a vehicle truck assembly which includes a spring coupling an axle carrier to a truck frame. In one example, the system comprises a substantially vertically-mounted hydraulic actuator which generates hydraulic forces between the axle carrier and the truck frame. The actuator includes a cylinder, a piston, and a piston rod. Further, the actuator is coupled between the axle carrier and the truck frame with longitudinal and lateral play so that the axle carrier can move laterally and longitudinally with respect to the truck frame while the actuator applies hydraulic force.
