Abstract: The present invention is for a system (11) or method for conditioned based monitoring of a bearing assembly. The system (11) comprises a sensor (13) placed in proximity to a bearing assembly (12). The sensor (13) generates a signal indicative of the amplitude and frequency of the vibrational movement of the bearing assembly. A process (14) in communication with the sensor (13) receives the signal from the sensor (13) and generates spectral data representative of the bearing vibrational movement. A database (15) comprises data representative of an amplitude threshold, for at least one predetermined frequency, characteristic of a bearing fault. The processor (15) compares the spectral data to the amplitude threshold and generates a signal indication of the bearing assembly.

Abstract: 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.
