Abstract: Method for spectral evaluation of oscillation signals which have been obtained on a rotor blade of a wind power installation with an accelerations sensor. In doing so, instead of the otherwise conventional Fourier transform calculation, the spectral power density is computed. In the evaluation, also signal portions are considered which are not detected in the Fourier transform because they do not go back to oscillations which have been excited in the rotor blade.

Abstract: In a method for obtaining information from a coding body (1, 15), information is assigned to a three-dimensional form of at least one portion of the coding body (1, 15), at least one two-dimensional image of at least the portion of the coding body (1, 15) is generated, the form of the portion is identified on the basis of the image and the information that has been assigned to the identified form is accessed. A corresponding system comprises: at least one coding body (1, 15) having at least one portion with a three-dimensional form that has information assigned; at least one image-capture means (8, 19, 24) for generating two-dimensional images; and at least one processor (9, 21, 25) configured to identify the form of the portion on the basis of at least one two-dimensional image of at least the portion of the coding body (1, 15) and to access the information assigned to the identified form.

Abstract: The invention relates to a method for determining the root mean square value of a vibration variable that is measured on a machine. A test measurement is carried out in order to obtain a test signal of the vibration variable with a test signal length; the influence of shortening the signal length of the test signal on the associated root mean square value is estimated and the relative deviation of the root mean square value emerging for a shortened signal length from the root mean square value emerging for the full test signal length is estimated therefrom as a function of the signal length to obtain a root mean square value error function; and a measurement of the vibration variable is carried out for determining the root mean square value. The measurement duration of this measurement is selected on the basis of the root mean square value error function.

Abstract: A device for measuring cavities has a main body, at least one first distance sensor mounted on the main body and rotatable about an axis of rotation for contactlessly measuring distances in a radial direction with respect to the axis of rotation, a holder for fixing the device within the cavity in a position in which the main body assumes an orientation in which the axis of rotation of the first distance sensor coincides substantially with a center axis of the cavity, and at least one second distance sensor, arranged on the main body, for contactlessly measuring distances in a direction parallel to the axis of rotation, the axis of rotation passing through a detection area of the second distance sensor.

Abstract: A method for bringing two bodies (1, 2, 6, 7) into predetermined positions with respect to one another, which is carried out by an alignment system having data spectacles (smart glasses) (12). The dimensions of the bodies (1, 2 , 6, 7) and/or respective positions of the bodies (1, 2, 6, 7) are determined relative to each other by a data processing means (17) of the data spectacles (12) on the basis of images which are detected by an image detection means (16) of the data spectacles (12). Furthermore, an adjustment value is displayed in a display device 18 of the data spectacles (12).
