  • Systems and methods for predicting failure of electronic systems and assessing level of degradation and remaining useful life
    Patent number: 8600685
    Abstract: Disclosed are systems and methods for prognostic health management (PHM) of electronic systems. Such systems and methods present challenges traditionally viewed as either insurmountable or otherwise not worth the cost of pursuit. The systems and methods are directed to the health monitoring and failure prediction of electronic systems, including the diagnostic methods employed to assess current health state and prognostic methods for the prediction of electronic system failures and remaining useful life. The disclosed methodologies include three techniques: (1) use of existing electronic systems data (circuit as a sensor); (2) use of available external measurements as condition indicators and degradation assessor; and (3) performance assessment metrics derived from available external measurements.

  • Sensor for measuring jerk and a method for use thereof
    Publication number: 20060021435
    Abstract: Disclosed is a method and apparatus for measurement of the derivative of acceleration with respect to time (jerk) and the use of demodulation to analyze the jerk signal. The sensor used to measure jerk consists of a piezoelectric transducer coupled with an amplifier that produces a voltage or current signal that is proportionate to jerk. In applications including rolling element bearing diagnostics, demodulation is used to measure changes in the jerk signal over time.
