Patent ID: 7952360

Claim:
A method for passively monitoring a wire for defects, the method comprising: attaching a first sensor to a wire at a first location; attaching a second sensor to the wire at a second location; capturing a first segment of data from the first sensor, a second segment of data from the second sensor, and a time stamp when a pulse is detected in at least one of the first sensor and the second sensor; calculating a set of signal features associated with the pulse from the first segment of data, the second segment of data and the time stamp, using an analysis module comprising a curve fitting model, a noise model, an FFT model and a statistical model, each of which is used to generate at least one of the signal features; determining a defect decision that indicates whether or not the detected pulse represents a defect in the monitored wire using the signal features associated with the pulse; and storing the defect decision associated with the pulse and the time stamp in a storage database.
