“…Robert Hiergeist [21] proposed a Scanning of the under degree by using magnetic gradient sensors is the number one detection approach for unexploded bombs. Using the stray magnetic subject of the resulting magnetic second, the position of the bomb within the ground can be located through scanning the ground degree by one or greater fluxgate gradient sensors.…”

This paper provides the estimation through drone for surveillance and bomb diffusion the using actuators. The proposed model is composed that lightweight, portable and user pleasant with reduced complexity. The new glove system is a wi-fi and self-contained machine that's established at the user arm in an effort to control the motion of the robot. The device is not restricted to the variation inside the finger sizes thereby imparting accuracy and comfort for the robotic control. The system is ready with bomb detection and diffusion mechanism. Once the presence of bomb/Metal is detected by using robotic, it initiates commands to the legal officials and the detected bomb can be subtle from a remote area, it linked direct touch with the bomb. Thus the machine provides high security for the existence of the bomb diffusion squad. The proposed device is noticeably useful in the all regions that call for safety and it presents virtual fact in surveillance and diffusion.

“…In contrast to the abovementioned methods, a magnetic sensor based on magnetic anomaly detection is introduced in this study to measure the rotational speed. Magnetic anomaly caused by ferrous/magnetic object motion can be used to locate or identify the targets that have been extensively applied in the fields of traffic surveillance [12,13], banknote validation [14,15], archeological artifacts [16], and hidden ordnance [17,18]. The anomalous magnetic signal can be detected by field-sensitive magnetoresistance devices, including anisotropic magnetoresistance [19], giant magnetoresistance [20,21], and tunnel magnetoresistance (TMR) [22].…”

This study introduces a rotational speed measurement method based on magnetic anomaly detection to monitor the traveler’s speed in ring spinning. A structure and theoretical model of anomalous magnetic field detection were built. Rotational speed can be calculated from the output signal acquired through tunnel magnetoresistance. A testing system was developed to test sensor performance. The output signals of the sensor at different rotational speed, working gap, and fixed offset were experimentally investigated. The result showed that the proposed sensor can meet the rotational speed measurement requirement of ring spinning. Finally, the practical application of the sensor in a ring spinning machine was introduced. The result indicates that the system can satisfy the practical application of yarn break detection with the advantages of compact size, high sensitivity, strong anti-interference capability, good stability, high reliability, and so on. The method proposed in this paper has shown great potential in providing the production status of the spinning field.

Hiergeist et al built a ground level test facility to analyze signal resolution and the relative spatial resolution of MGT measured with unexploded bomb detection applications [ 13 ]. Bracken and Brown used a prototype tensor magnetic gradiometer system and designed a data-reduction procedure to detect UXO [ 14 ].…”

The detection of dipole-like sources, such as unexploded ordnances (UXO) and other metallic objects, based on a magnetic gradiometer system, has been increasingly applied in recent years. In this paper, a novel dipole-like source detection algorithm, based on eigenvector analysis with magnetic gradient tensor data interpretation is presented. Firstly, the theoretical basis of the eigenvector decomposition of magnetic gradient tensor is analyzed. Then, a detection algorithm is proposed by using the properties of the tensor eigenvector decomposition to locate dipole-like magnetic sources. The algorithm can automatically detect magnetic dipole-like sources without estimating the magnetic moment direction. It performs well for locating weak, anomalous dipole-like sources in air-borne magnetic data through quantitative interpretation. The effectiveness of the proposed algorithm has been demonstrated in the designed synthetic experiment. Finally, an air-borne magnetic field data taken at high altitude with exact source position information is used to validate the practicality of the proposed algorithm. All of the experiments prove that the proposed algorithm is suitable for magnetic dipole-like source detecting and air-borne magnetic gradiometer data interpretation.
