摘要：
Disclosed is an apparatus and methodology for detecting anomalies in cables within a tire structure. A plurality of magnetic field sensitive sensors are aligned within a magnetic field provided by a magnet. The alignment of sensors and magnet is such that flux lines from the magnet are generally parallel to the plane occupied by the magnetic sensors. A tire cable anomaly present between the magnetic field sensitive sensors produces a detectable difference in signals produced by the magnetic field sensitive sensors as a result of the formation of perpendicular flux patterns produced by the anomaly. A signal processing circuit receiving input signals from the sensors evaluates differences between the signals from each of the plurality of sensors by pairing the output signal from each sensor with the output signal from each of the others of the plurality of sensors and produces an output signal upon the differences meeting selected criteria. The output signal may include an externally measurable signal and/or ma
