Abstract: A ventilation system for a wind turbine generator system having a ventilation duct for conducting a cooling air that has been heated by waste heat from an air intake section of the ventilation duct to an air outlet section of the ventilation duct, along a flow path bounded by a duct wall which extends between the air intake section and the air outlet section, wherein in a sectional plane, preferably in every sectional plane that extends perpendicular to the flow path, the inside span of the ventilation duct can be adjusted by applying pressure to an outer boundary surface of the duct wall.

Abstract: A closure assembly for a vehicle includes a hook movable between locked and unlocked positions. An actuator is connected to the hook and is linearly movable to move the hook between the locked and unlocked positions. First and second rotatable gears are engaged with one another such that either gear rotates as the other gear rotates. First and second levers are respectively connected between the gears and the actuator. The levers move as the gears rotate in response to the first gear rotating in a first rotary direction and thereby cause the actuator to move linearly in a first direction to thereby move the hook to the locked position. The levers move as the gears rotate in response to the first gear rotating in a second rotary direction and thereby cause the actuator to move linearly in a second direction to thereby move the hook to the unlocked position.

Abstract: The invention relates to a method and to a device for the stroboscopic recording and reproduction of images of a repetitive process (12), especially of moving vocal chords (larynx diagnostics). The aim of the invention is to improve image quality, especially the brightness and definition of the images while requiring little lighting equipment. According to the inventive method, the process (12) to be observed is illuminated with a steady light source (14). Trigger pulses STrigger are generated to trigger exposures to record the image information of the process (12) by an image sensor (16). The image information from a plurality of subsequent exposures is added in a back-ground memory of the image sensor (16) to produce image information sums. The image information sums thus obtained are stored in the background memory (18) of the image sensor (16) and the background memory (18) is read and deleted, and the image information sums are processed to give a video signal.
