Abstract: A vehicle window pane having a plate-like window pane body which has an outer side which faces the surroundings of the vehicle and an inner side which faces away from the outer side and to which a composite is connected, the composite having a layer structure which may have multiple layers disposed one on top of the other, one of the layers having a liquid crystal arrangement having two films and a liquid crystal cell disposed between the two films, and another one of the layers being a polarizer layer. At least one layer of the layer structure can be a compensation layer whose area is smaller than the area of the liquid crystal arrangement, the liquid crystal cell thus having an edge portion which is thicker than a central portion covered by the compensation layer.

Abstract: The invention relates to a method for producing a component bond (70, 140) comprising: a fastening structure (60, 160) that has at least one component layer (60; 160a, 160b); and a thermoplastic connecting element (10, 110) having a head (12) and a shank (14), in which method the connecting element (10, 110) is driven into the fastening structure (60, 160) under pressure whilst rotating, such that the shank (14) penetrates the fastening structure (60, 160). The connecting element (10, 110), after penetrating the fastening structure (60, 160), is converted by friction into a softened, free-flowing state in a die (44, 144) which is placed against the fastening structure (60, 160) in the opposite direction to the driving direction, resulting in a thicker section (22, 22) that extends beyond the radial extent of some sections of the shank (14). The fastening structure (60, 160) is thus interlockingly held between the head (12) and the thicker section (22, 122).

Abstract: A device for ventilating and cooling the interior of a vehicle with at least one air guide channel (7) having air inlet openings (8) located in the rear of a solar cell equipped vehicle roof (5a, 5b), the air guide channel (7) being restricted to the rear area (3) of the vehicle roof (5a, 5b) and having at least one fan (15) for taking in outside air (10) and at least one cooling element (14) for cooling the air taken in. The bottom of the air guide channel (7) is formed by a first section (12) of a roof portion (5b) which extends from the vehicle rear toward the vehicle front (3, 1) and the top of the air guide channel (7) is formed by a second section (13) of a roof portion (5a) which extends from the vehicle front toward the vehicle rear (1, 3).

Abstract: The method according to the present invention is used for automatically configuring a fuzzy automatic-control device, in the form of generating transformation criteria. These transformation criteria preferably have change, stop, jump-back and reset rules for the individual states of the fuzzy automatic-control device that represent recognition probabilities. The method allows transformation criteria for configuring fuzzy automatic-control devices to be produced fully automatically by the arithmetic logic unit. Even if the pattern signals change frequently, the fuzzy automatic-control device can thus be reconfigured quickly, flexibly and without complications.
