  • Patent number: 8688393
    Abstract: A system includes a capacitance adjustment module and a control module. The capacitance adjustment module is configured to connect one or more of N capacitors in parallel with one of a first and second capacitance. The control module identifies the smaller of the first and second capacitances and identifies the larger of the first and second capacitances. Subsequently, the control module, during each of M iterations, instructs the capacitance adjustment module to connect at least one of the N capacitors across a set of nodes in parallel with the smaller identified capacitance, and determines whether the capacitance associated with the set of nodes is greater than the larger identified capacitance. After the M iterations, the control module approximates the difference between the first and second capacitances based on which of the N capacitors are connected across the nodes. M and N are integers greater than or equal to 1.

  • Patent number: 8682612
    Abstract: There is described herein the extension of the application of the Laplace Test Statistic for trend analysis and prediction of incipient faults for power systems. The extensions consider the situation where two parameters believed to contribute explicitly to the eventual failure are monitored. The developed extensions applied to actual incipient failure events provide promising results for prediction of the impending failure. It is demonstrated that by incorporating two parameters in the trend analysis, the robustness to outliers is increased and the flexibility is augmented by increasing the degrees of freedom in the generation of the alarm signal.

    Abstract: A method of detecting the position of a wavefront in a time-varying signal corresponding to an event is disclosed. According to one aspect, the method includes digitizing a signal received by a detector to produce a working signal, filtering the working signal N4 times with a band-pass filter to obtain N4 filtered working signals with different pass-bands, detecting a peak of the N4 filtered working signals to detect the position of a first wavefront as a function of time of occurrence. The N4 points are plotted such that an ordinate is one of the times of occurrence and an abscissa is the width of the associated band. An exponential asymptote that fits a maximum number of the N4 points is applied, and the position of the wavefront is determined as the ordinate of the point that has the maximum abscissa and substantially fits the exponential asymptote.

  • Patent number: 8676543
    Abstract: Mechanical oscillators employ the use of resonance parameters, frequency and the quality factor Q, for the measurement of corrosion or deposition. The ability of a mechanical oscillator to measure small amounts of metal loss or deposition is not only dependent upon the mechanical design but is limited by the precision in determining the resonance frequency and Q. Methods for measuring these resonance parameters with a high precision in the presence of noise are provided. The increased degree of precision improves the utility of these devices as sensitive probes for corrosion and deposition (fouling) measurement. The increased degree of precision is enabled in part by employing curve fitting consistent with modeling the mechanical oscillator as a simple harmonic oscillator. This curve fitting procedure, combined with averaging and utilizing signal processing parameters to mitigate noise effects, adds precision in measuring resonance parameters.

  • Patent number: 8675327
    Abstract: The present invention relates to methods for providing impedance protection differentiating between in-zone and out-of-zone faults based on instantaneous, digitally derived operating and polarizing distance comparator signals. The method uses a pair of fast orthogonal filters to derive D and Q components of the input voltages and currents. Two sets of operating and polarizing signals are derived for better speed of response under varying fault moment with respect to the peaks and zero crossings of power signals. Three stages of comparison between the operating and polarizing impedance terms are used. These comparator stages use half a cycle averaging windows, and three-quarters-of-a-cycle windows. The first stage of comparison is based on energy comparator responding to both magnitude and phase information in the signals. Stages 2 and 3 are of phase comparison type, responding mostly at the phase information and neglecting the magnitude information for better immunity to noise and signal distortions.

A searcher searches for a highest amplitude value in each subsignal, which is determined to be non-gaussian. A generator may form a radio channel for a radio channel simulation, the radio channel including each propagation path corresponding to the highest amplitude value in each subsignal determined to be non-gaussian.

  • Publication number: 20130317767
    Abstract: In a measurement error correction method and an electronic component characteristic measurement apparatus, for each of correction-data acquisition samples having electrical characteristics different from one another, electrical characteristics SD, ST are measured in a first state in which the correction-data acquisition sample is mounted on a standard fixture and in a second state in which the correction-data acquisition sample is mounted on a test fixture, respectively. For each signal source port of a measurement system including a measuring instrument for measuring electrical characteristics, a mathematical expression that assumes the existence of a leakage signal that is transmitted directly between at least two ports of at least one of the standard fixture and the test fixture is determined. Electrical characteristics of a given electronic component are measured in the second state.
