Abstract: An inkjet printer for producing graphic or functional products, the inkjet printer having integrated optical monitoring of the correct function of each of the nozzles that shoot the ink onto the substrate. For this purpose, the drops ejected from the nozzles are illuminated from the direction of the ejecting nozzles, and the light reflected backwards from the drop flying away is conducted onto light-sensitive sensors during the flight of the drop.

Abstract: An incremental transducer (1) as well as a process (D1) are provided for determining an actual position of a body (5) along a measuring path (W) and/or a change therein. A position code (7) of the incremental transducer (1) has a gap (10). To make it possible to use the incremental transducer (1) as flexibly as possible and to operate it despite dimensional tolerances of the body (5), provisions are made for converting an actual location frequency (Fi) of the position code (7) into a desired location frequency (Fs) that is independent from the length (L) of the gap (10) to generate a position signal (S) representative of the actual position or the change therein.

Abstract: A wind power rotor with measuring device (3) for measuring rotor deflection. A measuring cavity (20), which has a transmitter/receiver (31/32) at one end and a reflector device (33) at the other end, extends in a longitudinal direction of the rotor. The transmitter/receiver (31/32) is accommodated in a housing (50), which is fastened to an intermediate plate (10) with three-point mounting (12, 13, 14).

Abstract: A device and method for arranging a housing in a specified position relative to a reference object. For positioning and/or aligning a housing with respect to a reference object, a detachable positioning element is constructed on the housing. The positioning element comprises at least one stop element that is brought into contact with the reference object. The positioning element also comprises a carrier arm that connects the housing and the stop element, wherein the connection of the carrier arm to the housing is designed as a fracture point. After mounting the housing in the desired position, the positioning element is separated from the housing.

Abstract: A device and process for measuring the deformation of a rotor blade under stress is provided. A twisting and, separately therefrom, a lateral displacement of a transmitter/receiver is measured and the error of measurement present otherwise due to the twisting is compensated.

Abstract: An absolute value transducer (1) for determining an absolute position (P) of a body (6), with a measured material element (5), as well as a process for determining the absolute position (P) of two bodies (3, 4, 6) in relation to one another. In order to be able to use the absolute value transducer (1) in as flexible a manner as possible and to detect mounting errors of the measured material element (5), provisions are made according to the present invention for a code (K) of the measured material element (5) to have a discontinuity (9) in its course and for the code (K) to be scanned outside the discontinuity for determining the absolute position (P) within the discontinuity (9), and for the scanned absolute values (W) to be combined with an offset value (A).

Abstract: The invention relates to an automatic system for repairing surfaces having natural patterns, particularly wood panels, wherein after the automatic detection and repair of the faulty regions by smoothing or doweling, the Visually apparent repair regions are decorated loudly by a numerically controlled decoration process, particularly an ink jet printing technology. To this end, the panel is captured optically by a scanner, which in particular can detect colors, in addition to an image generator suitable for detecting the faulty regions. From the global color and structure characteristics of the panel and the local color and structure characteristic of each individual faulty region, local decoration patterns to be applied automatically are derived, which allow the faulty region to not be apparent any longer and give the panel a desired aesthetic appearance both locally and globally.
