    Abstract: A measuring device is provided which, in order to measure measured variables of an object being measured, can be placed on a surface of the object being measured. The surface supports the measuring device. The measuring device comprises at least three projecting contact surfaces, the center points of which are distributed substantially uniformly along a circle. The projecting contact surfaces, when the measuring device is placed on the surface of an object being measured, lie against the surface and are supported by the surface. A first of the contact surfaces comprises a temperature sensor for measuring the surface temperature of the object being measured, while a second and a third of the contact surfaces are provided to measure respective other measured variables.

    Abstract: A device for determining the position of a first mechanical element relative to a second mechanical element, having a first measurement unit for attachment to the first mechanical element, a second measurement unit for attachment to the second mechanical element, and an evaluation unit. The first measurement unit emits spectrally differing first and second light beams in essentially the same direction and a position-sensitive optical detector. The second measurement unit has a reflector arrangement facing the first measurement unit, in order to reflect the first and second light beams onto the detector. Surfaces facing the first measurement unit being color splitters having different reflectivity/transmissibility for the first light beam and the second light beam. The evaluation unit determines the location of the first and second mechanical elements relative to one another from the incidence positions of the reflected first and second light beams on the detector.

    Abstract: A vibration-resistant wind turbine and process for operation is provided. The wind turbine has a rotor with at least two blades, each of which includes an inclinometer arrangement with at least two axes, and an evaluating unit. The evaluating unit determines the bending and/or twisting of the blade relative to the longitudinal axis of the blade on the basis of signals from the inclinometer arrangement for each blade during operation. Each rotor blade further has at least one liquid tank which is capable of receiving or transferring liquid from or to a liquid reservoir via a transfer mechanism in response to the determined bending and/or twisting of the rotor blades to reduce vibration caused by imbalances, thereby extending the service life of the wind turbine.

    Abstract: The method provides determining at least one speed of a machine, wherein, on the basis of the measurement of a vibration variable carried out on the machine over time, the complex spectrum of this variable is determined, wherein a frequency interpolation is carried out; boundary conditions are established for the evaluation of the spectrum, which include the permissible frequency range of an expected main speed, a set of relative frequencies with respect to the main speed in the form of frequency multipliers, and a weighting factor for the particular relative frequency; a spectral probability density is calculated with consideration for the boundary conditions, which results for each frequency of the permissible frequency range as a sum of the amplitude of the spectrum, which has been weighted with the particular weighting factor and the main speed is determined on the basis of the frequency having the maximum probability density.
