Abstract: An underroof collar for use in water-proofing the joint between a roof structure and a window frame is disclosed. It includes a plurality of collar members adapted for extending along frame member of the window frame, and each collar member includes an inner rim part and an outer skirt part intended for coming into engagement with the roof structure. The underroof collar is provided with at least one first engagement zone for positioning the underroof collar by bringing the first engagement zone into contact with a second engagement zone on another object, said first engagement zone being exposed in a packed state of the underroof collar. The first engagement zone may include a fastener and/or a cover layer. A packed underroof collar and a method for providing an underroof collar is also disclosed.

Abstract: The invention includes an optics array for beam shaping, which uses a micro lens combination, whose polygonal micro lenses are arranged in a level, whereby the geometric arrangement of the individual lenses and their diameters follow a distribution pattern. It is characterized by the fact that the number of corners as well as the length of the lens rims of each of the individual lenses of the micro lens combination is defined by a point distribution (P) of Voronoi points (2), which define a Voronoi Region (VR(p)) which can be described by the following equations for a Voronoi lens (1).

Abstract: The roof window assembly comprises a main frame component and a window component including a glazing element. In order to reduce the influx of light an external screening accessory is provided. The screening accessory comprises an elongate housing extending in parallel with the top and bottom members of the frame and from which a screening member is retractable by movement parallel to the side members of the frame. An end member connected with a free end of the screening member extends throughout the width of the window frame and includes engaging means at either end of the end member for engagement with a transverse inwards recess in the outer side of each side member of the window frame.

Abstract: The invention relates to an array for reducing the coherence of a coherent radiation beam (6), wherein a reflector (1) defining an inner space is provided with a diffusely reflecting inner surface (4), wherein said reflector (1) has an inlet hole (2) through which the radiation beam (6) can be injected into the inner space, in addition to an outlet hole (3) through which the rays of the radiation beam (6) can come out after at least one reflection on the inner surface (4).

Abstract: An apparatus for sensing electromagnetic radiation with local resolution for image-producing sensors that can be economically produced and installed is decribed. This is achieved, in that a micromechanically producible optical imaging system is provided.

Abstract: A roof window assembly is composed of a window component, a main frame component and, optionally, an integrated flashing component. The window component may be used independently and without modifications for a roof window installation employing a curb-frame. The window component features a novel design with an glazing element fitted in a profiled sheet metal frame, which can be made from a single continuous sheet metal profile bent into a polygonal frame shape with corner junctions. In both fixed and ventilating versions of the roof window assembly identical connecting members into open mutual engagement at the top side of the window and main frame components provides for easy mounting and dismounting of the window component with respect to the main frame component.

Abstract: The window frame structure of the roof window is secured to the main frame structure within a predetermined range of the opening angle by means of a securing device comprising at least one torsion member. The torsion member is torsionally biased in the opening direction of the window and includes engagement means at a distance from the pivot axis for engagement with corresponding engagement means on the window frame structure. The securing device is automatically activated and deactivated during mounting and dismounting of the window frame from the main frame.
