Abstract: The invention relates to a method and a device for determining the position of defects or damage on rotor blades (4) of a wind turbine (1) in an installed state, comprising the steps: a. a localisation instrument (5) is guided along the rotor blade (4) and the defect or damage is detected; b. the localisation instrument (5) has a GPS module (6) by means of which the GPS data of the localisation instrument (5) is detected at the defect or damage; c. the position of the investigated wind turbine (1) is detected by means of the GPS module (6); d. using the position data of the wind turbine (1), the hub height (n) of the wind turbine (1) is retrieved from a database and the distance (d) of the defect or damage of the rotor blade (4) from the hub (34) is calculated in an evaluation unit (8) from the difference between the GPS data of the localisation instrument (5) and the hub height (n) of the wind turbine and in accordance with the rotor blade position.

Abstract: The invention relates to a method for testing a rotor blade (13.1) of a wind power plant (1), which sweeps across a rotor blade surface to be covered during operation of the wind power plant, comprising the following steps: emitting a target light beam (20), in particular a target light beam having a power density, in a direction of the target light beam onto the rotor blade surface to be covered; detecting a possible reflection of the target light beam by a detection device at a point of incidence (16) on the rotor blade; electrically controlled emission of a measurement laser beam (21) which has a power density that is larger than the power density of the target light beam immediately after detection of the reflection at the point of incidence so that the rotor blade is heated at the point of incidence; measuring a temperature distribution at the point of incidence; and repeating the steps (a) to (d) for several points of incidence.

Abstract: The invention relates to a method for detecting process parameters when making wood products (6), especially wood panels, which are hot-pressed by applying pressure and heat, as well as a wood product (6). In said method, at least one measuring instrument (3) is introduced into the non-pressed starting material (2) during the on-going production process of the wood products (6) in order to detect the pressure, temperature, and/or humidity and remains in the end product (6). The measured process parameters are read in a wireless manner.
