Abstract: An electromechanical actuator includes a base part and an oscillation resonator having the shape of a rod. The electromechanical actuator further includes amount for mounting the oscillation resonator to the base part. The mount is configured to bear the oscillation resonator so as to be rotatable around an axis of the oscillation resonator rod relative to the base part. A driver member is mechanically coupled to the oscillation resonator. A slider or a rotator is configured to be moved by the driver member when the oscillation resonator is excited.

Abstract: An electromechanical actuator includes an oscillation resonator having the shape of a rod. The oscillation resonator is divided by a dividing plane that is not parallel to the longitudinal direction of the oscillation resonator into a first resonator portion and a second resonator portion. At least the first resonator portion includes electromechanical means which, when activated, are configured to generate a 3-dimensional acoustic bulk wave are with a mode shape asymmetric with respect to the dividing plane.

Abstract: A device for absolute distance measurement includes a first tunable light source for emitting a first wavelength light of a first tunable frequency modulated by a first modulating frequency and a second light source for emitting a second wavelength light of a second frequency modulated by a second modulating frequency. An optical coupler couples the first wavelength light and the second wavelength light into an interferometer cavity. An interferometer detector provides an interference measurement signal based on a detected interference pattern. A demodulator unit generates a first demodulation signal based on the interference measurement signal by demodulation with the first modulating frequency and a second demodulation signal based on the interference measurement signal by demodulation with the second modulating frequency. A computation unit computes an absolute distance by evaluating the first demodulation signal acquired during a sweep of the first tunable frequency and the second demodulation signal.

Abstract: A method and a device for extracting a liquid from a liquid pond, wherein in a first phase air is removed from an airtight reservoir, a venting and a rising pipe in order to create depression therein and a suck-up of the liquid in the liquid pond. In a second phase, a distribution device is brought from a first to a second operating position in order to supply pressurized gas to said venting pipe which has an outlet connected to the rising pipe. In a third phase the liquid is pushed from the venting pipe to the rising pipe and thereafter to the reservoir by means of pressurized air and an interface member. In a fourth phase the distribution device is brought back to its first operation position.
