A locomotive diagnostic system. A first sensor outputs a measurement of a first state variable (such as vibration) of a first locomotive component, such as a blower fan bearing set, and a second sensor outputs a measurement of a second state variable (such as rotational speed) of a second locomotive component, such as a blower fan shaft. The first state variable is indicative of the operation of the first component and is dependent on the second state variable. Data represents, for each of a number of different values of the second state variable, first, second, and third ranges of values of the first state variable which indicate, respectively, normal, worn, and failed operation of the first component. A mechanism, such as a digital computer, determines if the measurement of the first state variable is within the first, second, or third range of values of the first state variable for the measurement of the second state variable.

A self-shielded gradient coil assembly for an MR imaging system has inner and outer gradient coil windings disposed in coaxial relationship and defining a hollow annular space therebetween. Inner and outer helical cooling tubes are affixed to the outer and inner surfaces of the inner and outer gradient coil windings, respectively, by a thermally conductive epoxy, and a concrete filler material substantially fills the remaining hollow annular space. The concrete filler material may be poured into the hollow annular space to fill the space, or a pre-formed hollow concrete cylinder may be inserted coaxially into the space, defining remaining inner and outer annular volumes which are then filled with a thermally conductive epoxy bonding together the inner and outer gradient coil windings, the cooling tubes and the hollow concrete cylinder.

The present invention is for a system ( ) or method for conditioned based monitoring of a bearing assembly. The system ( ) comprises a sensor ( ) placed in proximity to a bearing assembly ( ). The sensor ( ) generates a signal indicative of the amplitude and frequency of the vibrational movement of the bearing assembly. A process ( ) in communication with the sensor ( ) receives the signal from the sensor ( ) and generates spectral data representative of the bearing vibrational movement. A database ( ) comprises data representative of an amplitude threshold, for at least one predetermined frequency, characteristic of a bearing fault. The processor ( ) compares the spectral data to the amplitude threshold and generates a signal indication of the bearing assembly.

In one embodiment, the invention is a pressure sensor calibration system comprising a pressure chamber in fluid communication with a pressure sensor to be calibrated, the chamber is pressurized to a static pressure level. An oscillating surface on a wall of the chamber imparts a rapid pressure fluctuation in the static pressure level of the chamber. These rapid pressure fluctuations in a high-static pressure level chamber are used to calibrate the pressure sensor.

A system for monitoring the condition of a vehicle has at least one wireless transmitter in on the vehicle, and in communication with the vehicle computer system. Data representative of operating parameters generated during the operation of the vehicle is downloaded to the transmitter, which transmits the data to a wireless receiver positioned proximal to a path of travel of the vehicle. The receiver is linked to a processor for transmission of the data to the processor for storage and processing if necessary. The system may also include at least one sensor, positioned proximal the path of travel, for detecting a physical phenomenon emanating from at least one vehicle component. The sensor generates a signal, which is transmitted to the processor. The processor is capable of analyzing the signal generating data indicative of operating condition of the vehicle component. The sensor, and/or receiver, mounted to a structure positioned proximal the path of travel of the vehicle.

A system and method are provided to monitor the health of a wind turbine gearbox. The system includes a plurality of sensors coupled to the wind turbine gearbox and a controller coupled to the plurality of sensors. The controller is configured to acquire vibration information from a vibration sensor, acquire a tachometer signal, convert the tachometer signal and the vibration information into a cycle domain signal, and perform an order analysis on the cycle domain signal, the order analysis providing information that identifies potential and actual damage within the wind turbine gearbox.
