Driver Circuit Design for a New Eddy Current Sensor in Displacement Measurement of Active Magnetic Bearing Systems

Position sensing is one of the crucial parts of the active magnetic bearing (AMB) system. The printed circuit board (PCB) eddy current position sensor is a new type of position sensor for the AMB system, which makes a compact structure, high sensing quality, and is low cost. In this article, an improved driver circuit is proposed for this new...

Extended Object Tracking of Pedestrians in Automotive Applications

Recent advances in sensor technology have lead to increased resolution of novel sensors, while tracking applications where distance between sensors and objects of interest is very small have gained research interest recently. In these cases, it is possible that multiple sensor detections are generated by each object of interest. Extended Object...

6-DoF Stage Position Measurement Concept for Microscopy with one 2D Position Sensitive Detector (PSD)

Background Interferometers and capacitance sensors were used to measure the motion of the 6-DoF ferrofluid planar bearing positioning stage designed by Max Cafe who was the master student graduated in 2014. The sensor costs almost 30,000 euro to achieve nanometer scale accuracy. However, in some biology applications, such as observation of...
