    Abstract: A magnetic body inspection method and magnetic body inspection apparatus (1) that has a magnet (10) and a magnetic sensor (20) that outputs electric signals. At least two electric signals are obtained by the magnetic sensor (20). A magnetic body present inside a nonmagnetic body can be detected non-destructively, by outputting the difference between the two obtained electric signals.

    Abstract: A passive magnetic detection and discrimination system and method is disclosed. The system comprises at least one sensing structure having a plurality of magnetic inductive sensors arranged on a rigid framework; at least one screening area defined by one or more sensing structures, whereby the plurality of magnetic inductive sensors are configured to respond to a magnetized object passing thereby; and a processor and a memory operatively connected to the plurality of sensors and configured to receive data corresponding to amplitude waveforms created in each of the plurality of sensors by the magnetized object. Based on characteristic waveforms created by the magnetized object passing by the plurality of sensors, the system is configured to detect and discriminates the magnetized object. In another embodiment, the system utilizes an artificial intelligence or machine learning module to improve identification of a magnetized object based on the characteristic waveforms created by the magnetized object.

    Abstract: A method is provided for determining the geometry of a metallic object, with in particular one or more real, examined defects, with a reference data set of the object generated on the basis of at least one measurement by at least one non-destructive measuring method, preferably comprising an at least partial representation of the object on or by an at least three-dimensional object grid by means of a computer unit. A classification of anomaly-free areas and anomaly-affected areas of the object is performed on the basis of at least parts of the at least one reference data set. An initial object grid is created, a prediction data set of the at least one non-destructive measurement method is calculated by a simulation routine using the initial object grid, at least parts of the prediction data set are compared with at least parts of the at least one reference data set, excluding the anomaly-afflicted regions, and the initial object grid is used as an object grid describing the geometry of the object as a function of at least one accuracy measure, or the initial object grid is iteratively adapted to the geometry of the object in the anomaly-free regions by means of the EDP unit.

    Abstract: 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.

    Abstract: A non-destructive testing device for detecting damage to a steel wire rope, including a bushing which limits a lower shell and an upper shell through a limiting groove. The lower shell is connected to the upper shell via an opening and closing structure. An air bag is wrapped around the bushing. A PCB is fixed on the upper shell or the lower shell. The PCB is connected to a guide wheel via an electrical connector. A magnetoresistive sensor array is arranged inside the air bag and is uniformly arranged in a circumferential direction of the bushing. A steel wire rope passes through the magnetoresistive sensor array. And when the steel wire rope moves, it drives the guide wheel to rotate and triggers the acquisition of a command. Guide wheel is set with a position coder which is used to calculate a relative position of movement of the steel wire rope. The PCB is connected to a single chip microcomputer via a peripheral interface. And the single chip microcomputer is used to calculate a differential signal of N adjacent magnetoresistive sensors and to determine whether the steel wire rope is damaged. The capability of this non-destructive testing device for detection of a broken wire, a narrowed diameter, and deep damage of the steel wire rope is improved.
