The Federal Institute for Material Science and Technology (EMPA) uses – at its branch in Thun – a tribometer to determine the specific abrasion properties of two samples rubbing on each other. Our task was to expand and modernize the tribometer, so friction force and the normal force can be measured in high temperature experiments. In addition we integrate an automatic control for the temperature and the rotation speed of the samples.
The aquatic research institute Eawag conducted, in collaboration with Energie Wasser Luzern (EWL), an evaluation of the fish ladder at the hydroelectric plant Mühleplatz in Lucerne. Thereby, video footage of fishes passing by an observation window was captured and manually evaluated, which was very labor intensive. We searched for a software approach to automatically analyze the video footage. The task was to detect the fishes’ species, its swimming direction and count the number of passes in front of the camera.
In this fist project at the University of Applied Science we tried to realize a force feedback on the model of the surgical robot.
Scratcher device which was designed for the Group for Thin Film Physics at the ETH Zürich. The group was developing a novel, flexible solar cells. The solar cells were made of thin films of Mo, CIGS (Cu, In, Ga, Se2) and ZnO. For research purposes these films were manufactured in vacuum chambers on glass plates. The scratcher was meant to structure the film on the glass plate into individual cells.
Manipulators for instruments used under high vacuum must be strictly air tight. This manipulator allows to rotate and shift an instrument placed in a high-vacuum chamber. Manipulation was transmitted via a magnetic coupling.
Precision manipulator to position (rotated and shift) two mirrors for UV-laser applications.
