    • Practical apparatus that reports tyre status simplistically comprises a magnet (1) inside a wheel that will (proportional to proximity at the bottom) induce differing magnetic polarisation patterns into the steel bracing (7) in a tyre (5). When tyre profile is wrong due to under inflation the magnet will be closer and polarisation will differ. As wheel rotates the moving magnet filed will make a non rotating sensor generate signals that are processed by suitable electronics to deduce the tyre status and if differing from a pre-determined reports unsafe tyre conditions. Polarisation is then erased by another magnet housed with the sensor and the system is automatically reset to monitor the tyre status each revolution. Effectively the apparatus acts as an endless loop recorder to record play and erase status of and on revolving tyre. This invention enables the apparatus to be simple and cheap to make and maintain while being efficient in operation.
    • 简单地报告轮胎状态的实用装置包括轮内部的磁体(1),其将(与底部的接近度成比例)在轮胎(5)中引起不同的磁极化图案进入钢支架(7)。 当轮胎轮廓由于膨胀不足而导致磁体变得更近并且极化将会不同。 当轮旋转时,移动磁体将使非旋转传感器产生由合适的电子装置处理以产生轮胎状态的信号,并且如果与预先确定的报告不安全的轮胎状况不同。 然后通过与传感器一起安装的另一个磁体擦除极化,并且系统自动复位以监测每一轮的轮胎状态。 有效地,该装置用作无限循环记录器以记录和循环轮胎的播放和擦除状态。 本发明使得设备在操作有效的同时能够简单且便宜地进行维护。
