ALOP-Colloquium with Prof. Dr. Armin Fuegenschuh
19. January 2017 / 16:15 - 18:00
On Thursday, January 19, 2017, Prof. Dr. Armin Fuegenschuh from the Helmut Schmidt Universitaet Hamburg will join the ALOP-Colloquium and present his recent work entitled
Design Issues for Magnetic Rulers
We deal with the design of a magnetic ruler as an absolute positioning system. Trapezoid-shaped magnetic areas are placed side by side, so that the resulting pattern enables a unique encoding of each position up to a micrometer level. The problem of finding a longest-possible ruler from a set of elementary magnetic areas is formulated as a linear mixed-integer problem, and solved with a mixture of a heuristic and an extact approach. We demonstrate how to approximate the magnetic signal, using measured data from Hall sensor cells. From there, we discuss how the absolute position is recovered. Practical problems, such as measuring in an unknown altitude, are addressed.
