TL;DR: In this article, an inductive sensor system for speed, location, and direction detection of a moving object or moving component using a single Inductive sensor system has been proposed, which can be used as feedback in a motion control system.
Abstract: Apparatus and methods have been developed to provide speed, location, and direction detection of a moving object or moving component using a single inductive sensor system. Direction detection, speed detection, and location detection may be provided by the same inductive sensor and used as feedback in a motion control systems. Control systems of tractors, draglines, power shovels, and cranes may be easily upgraded with added safety, precision control, and automation using the inductive sensor system described herein.

TL;DR: In this article , a customized design of an inductive transducer and crack detection system on railroad tracks is proposed to avoid the train accidents. But, it is not suitable for the use of human errors and this involves human errors.
Abstract: The objective of this paper is to provide a solution to a serious issue in today’s world of transportation through railways. The practice to examine the flaws which leads to serious effects in rail track is rail inspection. Among the world countries, Indian railways are the fourth-longest, but when it comes to reliability and safety it lags to provide world standard. As a result, if the track is damaged, it leads to severe loss of valuable human lives and property. This derailment in tracks is caused due to cracks in the rails. Therefore, an early crack detection and protection system is required to save the lives. This paper proposes a customized design of an inductive transducer and crack detection system on railroad tracks to avoid the train accidents. Existing method uses the manpower to identify the cracks and this involves human errors. So, the drawbacks in the existing method can be reduced by the automatic system. Customized inductive sensor is designed and developed using ANSYS. A scaled down model of a cart is fabricated and the inductive sensor is assembled at beneath surface of the cart. The track is acting as a part of the magnetic core for the inductive sensor and voltage is induced in the sensor. The sensor voltage is calibrated to distinguish the magnitude of voltage from the normal to crack.

TL;DR: In this article , a probe-type inductive angular displacement sensor based on time-grating was proposed for large-diameter hollow rotary table position detection of the heavy-duty machine tools.
Abstract: This articledevelops a novel probe-type inductive angular displacement sensor based on time-grating, which is suitable for large-diameter hollow rotary table position detection of the heavy-duty machine tools. It abandons the traditional sensor precise marking lines in spatial domain, and integrates the tested mechanical component with the sensor, which realizes the angular displacement measurement directly. The sensor is divided into three parts: 1) a permalloy probe, which is adopted the simple structure to reduce the assembly errors; 2) a 45-steel rotor, which is a standard spur gear in a heavy-duty machine tool rotary table transmission system; 3) three groups of copper coils, which include sinusoidal coils, cosine coils and inductive coils. The theoretical model of angular displacement measurement is derived by means of mathematical equation in detail. Then the feasibility of the sensor structure is verified by finite element simulation. After that, a sensor prototype is built and tested in the laboratory, showing that the sensor has an original error of ±0.018° (approximately ± $64^{\prime \prime }$ ) over a full 360° range. The error analysis found that the systematic error is the main component. As a result, the mechanical structure and angular displacement algorithm of the sensor are optimized, which can significantly reduce the original errors of the sensor. After optimization, the final accuracy of the sensor is within ±0.0012° (approximately ± $4.4^{\prime \prime }$ ) in the range of 0°–360°.

TL;DR: A real time structural monitoring system by presenting a sensor node with embedded electronics which can be deployed by the I-wall to monitor the health and report back to base station in case of failure detection.
Abstract: Scouring is the major component of levee failures causing floods thus make the scour monitoring very important. There exist some on field mechanisms to monitor the health of the levees but there is still need for a remote, low cost and real time monitoring system. This paper proposes a real time structural monitoring system by presenting a sensor node with embedded electronics which can be deployed by the I-wall to monitor the health and report back to base station in case of failure detection. The sensor node use Magneto Inductive (MI) communication.
