Mikrointerferometer auf Basis von interferenzoptischen Stehende-Welle-Sensoren

Seit dem Michelson-Morley-Experiment im Jahr 1887 werden Interferometer erfolgreich in Forschung und Industrie für verschiedenste Aufgaben eingesetzt. Laserinterferometer sind heute hochentwickelte und enorm leistungsfähige Geräte mit beachtlichen Parametern hinsichtlich Messauflösung und Messunsicherheit.…

Ultrasonic excitation during press-fit joining of electrical contacts

Ultrasonic excitation of pins during a press-in process can reduce the press-in force. There are various theories describing the reason for the force reduction. In this paper, the printed circuit board (PCB) was excited to reduce the press-in force. The advantages of this process in comparison with the…

A novel framework for synchrophasor based online recognition and efficient post-mortem analysis of disturbances in power…

Synchrophasor based applications become more and more popular in today’s control centers to monitor and control transient system events. This can ensure secure system operation when dealing with bidirectional power flows, diminishing reserves and an increased number of active grid components. Today’s…
