Radar vibration sensors have been proposed for such stand-off preventive maintenance assessment. However the calibration of such a sensor is difficult for several reasons. The magnitude of the sensor response depends on the distance to the target. The magnitude of the response is roughly proportional...
In an illustrated embodiment, pressure sensors are placed between a turn-up bladder and a tire apex in tire building equipment, and the pressure applied by the equipment, and the sequence of pressure application are observed and are correlated with product quality....
