    • 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 may include a visual signal indicating presence of a tire anomaly.
    • 公开了一种用于检测轮胎结构内的电缆异常的装置和方法。 多个磁场敏感传感器在由磁体提供的磁场内对准。 传感器和磁体的对准使得来自磁体的磁通线通常平行于由磁性传感器占据的平面。 存在于磁场敏感传感器之间的轮胎电缆异常由于由异常产生的垂直通量图形的形成而产生由磁场敏感传感器产生的信号的可检测差异。 从传感器接收输入信号的信号处理电路通过将来自每个传感器的输出信号与来自多个传感器中的其他传感器的输出信号的输出信号进行配对来评估来自多个传感器中的每一个的信号之间的差异,并产生一个输出信号 差异符合选定标准。 输出信号可以包括可外部测量的信号和/或可以包括指示轮胎异常存在的视觉信号。

    • An apparatus and method for high voltage discharge testing of a tire is disclosed. In particular embodiments, a high voltage probe is maintained against the surface of a tire. The high voltage probe is energized and relative motion is provided between the surface of the tire and the high voltage probe. At the presence of an anomaly that penetrates the insulating material of the tire surface, an electrical discharge will occur between the conductive spring electrode and a reference electrode. The reference electrode is positioned adjacent the bead portion of the tire such that the electrical discharge will travel from the high voltage probe through the anomaly in the surface of the tire to one or more carcass plies in the tire. The carcass plies will carry the electrical discharge to the bead portion of the tire, where the electrical discharge will pass to the reference electrode.
    • 公开了一种用于轮胎的高压放电测试的装置和方法。 在具体实施例中,高压探针保持抵靠轮胎的表面。 高压探头通电,轮胎表面和高压探头之间提供相对运动。 在存在穿透轮胎表面的绝缘材料的异常的情况下,在导电弹簧电极和参考电极之间将发生放电。 参考电极定位成与轮胎的胎圈部分相邻,使得放电将从高压探针行进通过轮胎表面中的异常到轮胎中的一个或多个胎体帘布层。 胎体帘布层将放电到轮胎的胎圈部分,其中放电将通过参考电极。
