Abstract: An example system includes a positioning surveillance system (PSS) to identify locations of objects that are movable throughout a space. The PSS is configured to identify the locations without requiring a line-of-sight between the objects. A control system is configured to determine distances based on the locations of the objects in the space and to communicate information to the objects that is based on the distances. The information is usable by the objects for collision avoidance.

Abstract: An indicator device for detecting a delamination of a composite material, including detecting a delamination of a composite material of a wind turbine or a wind turbine rotor blade is provided. The indicator device includes: A first part, a second part and an electric circuit. Therein, the first part comprises at least a part of a lower part of the electric circuit. The second part comprises at least a part of an upper part of the electric circuit. And the lower part and the upper part are electrically connected to each other at a predetermined breaking point forming the electric circuit in such a manner, that when the indicator device is in use in a composite material, if a delamination of the respective composite material occurs, the electric connection between the lower part and the upper part breaks at the predetermined breaking point, thus cutting the electric circuit.

Abstract: A rotor blade element and a method for improving the efficiency of a wind turbine rotor blade are provided. The wind turbine rotor blade element is adapted for mounting on the wind turbine rotor blade. The wind turbine rotor blade has a trailing edge, a suction side and a pressure side. The blade element has a trailing edge, a first surface and a second surface. The first surface forms a pressure side surface portion. The second surface has a suction side surface portion and a contact surface.

Abstract: A method of optimising a wind park construction is provided. The wind park includes at least a first wind turbine and a second wind turbine. According to the method, a first blade topology is selected for the first wind turbine depending on a noise optimisation parameter which is measured and/or predicted at a reference position at a distance from the wind park. A second blade topology is selected for the second wind turbine depending on an energy efficiency optimisation parameter.
