    摘要： Systems and methods for monitoring electrical contacts are provided. One method includes calculating an impedance of an electrical contact based on an electrical signal applied to the electrical contact and a measured electrical signal after passing through the electrical contact. The method also includes determining a condition of the electrical contact using the calculated impedance.

    摘要： In some aspects, the present invention provides a method for estimating at least one measurement/object property of a metal object. The method includes generating (102) a time-varying eddy current in a wall of the metal object utilizing a pulsed-signal transmitter. The method further includes measuring (104) the time-varying eddy current, fitting (106) the time-varying measured eddy current to a parameterized polynomial, and interpreting (108) the parameterized polynomial to determine one or more measurement/object properties of the metal object.
