Abstract: It is aimed to provide a wireless vehicle to vehicle communication system arranged for mounting on a vehicle's front side location, equipped to provide inter vehicle communication. The system comprises a wing assembly arranged for mounting on the vehicles front side location. The wing assembly houses one or more digital communications antennas and has a side portion that houses a first antenna at a first height and/or horizontal position, and a second antenna at a second height and/or horizontal position, different from the first height and/or first horizontal position and sufficiently away from the other metallic and/or electronic components, for the purpose of optimizing reception and/or transmission quality, by e.g. providing good coverage and diversity, and avoiding interference with each other.

Abstract: The present invention relates to a method for determining the presence or level of an analyte of interest and the use thereof. Further, present invention relates to an analytical system, a sampling tube and the use of the sampling tube and a nucleophilic derivatization reagent.

Abstract: A rotor blade of a wind energy plant having a main component of the blade and a blade tip, whereby the blade tip is releasably attached to the main component by means of a connection device and the connection device has a tip section attached to the blade tip and a base section attached to the main component of the blade to receive the tip section, whereby the tip section has at least one fastener that extends to the base section for attaching the tip section to the base section, and the fastener for performing the attachment can be actuated through an opening in the surface of the blade tip.

Abstract: The invention relates to a rotor blade of a wind power installation comprising a heating device for heating the rotor blade, arranged in the rotor blade in the area of its rotor blade surface, wherein the heating device has electrically conductive heating wires, and the heating wires run in a sinusoidal, wave-like and/or zigzag-shaped way, with an amplitude, defining a sinusoidal amplitude, wave height or respectively spike height, and a wavelength defining a period length, wavelength or respectively a distance between spikes, wherein the amplitude and/or wavelength varies along the heating wires in order to be able to adjust the specific areal heating performance of the heating device for each section.
