  • Bearing fault signature detection
    Patent number: 7421349
    Abstract: A device, and method, detects the presence of developing faults in rolling element bearings. Detection is accomplished by measuring the vibration of the apparatus in which the bearing is operating (motor, generator, engine, etc.) and searching for signatures unique to bearing faults. These signatures are predicted by a fault signature model and recognized by a detector, both of which are part of this invention.
