A non-destructive testing (NDT) system which includes a chassis, a NDT scanner which may be an ultrasound scanner, a drive system comprising at least one drive wheel and at least one drive motor, a guidance system operatively connected to the drive system for controlling the motion of the NDT system, and a magnet assembly for adhering the NDT 5 system to a ferromagnetic object, which magnet assembly is configured to be switched on or off as required.

The present disclosure relates to a method for identifying a coin, and more particularly, to a coin identifying method capable of simultaneously identifying a type of coin and whether the coin is defective. In the coin identifying method of the present disclosure, since the type of coin and whether the coin is defective are simultaneously determined, there is an advantage that efficiency and reliability of identification can be improved.

A method of using a sensor device for tire inspection is provided. Signals are received from multiples rows of sensors separated by a predetermined distance. The sensors are positioned next to the inner surface of the tire for inspection. Signals from the different rows of sensors are used to identify e.g., breaks in the reinforcements of the tire and also used to identify undesirable signals generated from vibration or jarring of the sensor device.
