Abstract: The invention relates to a method for multi-sensorial object detection, wherein sensor information is evaluated together from several different sensor signal flows having different sensor signal properties. For said evaluation, the at least two sensor signal flows are not adapted to each other and/or projected onto each other, but object hypotheses are generated in each of the at least two sensor signal flows and characteristics for at least one classifier are generated based of said object hypotheses. Said object hypotheses are subsequently evaluated by means of a classifier and are associated with one or more categories. At least two categories are identified and the object is associated with one of the two categories.

Abstract: Assistance systems are increasingly being used to assist vehicle drivers when driving their vehicles. To this end, a camera is used to record image data from the area surrounding a vehicle, and at least some of the image data (1) are shown on a display following object identification and image processing. After the image data have been recorded by the camera, they are processed using object identification in order to identify objects (2, 3) in the recorded image data. At least some of the objects (2, 3) which have been identified in this manner are highlighted when showing the image data (1) on the display. In this case, the identified objects (2, 3) are highlighted in such a manner that the image data (1) to be shown are divided into two types of regions. In this case, the first type of region comprises the objects (2, 3) which have been identified and are to be highlighted and a surrounding region (2a, 3a) which respectively directly adjoins the latter in a corresponding manner.

Abstract: A gas lance made of a fireproof material, having an entry surface and an exit surface, having channels having slit-shaped cross-section, which comprise an entry slit and an exit slit. In order to provide a gas lance in which the gas exits in such a manner that a good thorough mixing of the melt is achieved and a simple penetration of the melt by the gas is avoided, the projection of the exit slit of a channel onto the entry surface may be offset in relation to the entry slit of the channel.

Abstract: The invention concerns a device for improving the view in vehicles, in particular at night, bad weather and fog. In the process images of actual traffic scenes are recorded by a camera (2), which is sensitive outside the visible spectrum, and these images are reproduced in the visible spectrum in the vehicle via a display optic (6). According to the invention the type of object which is contained in a traffic scene recorded by the camera (2) is automatically classified according to type, and depending upon the type of the recognized object it is reproduced on the display optic (6) in an intensity and/or color, which corresponds to the intensity and/or color which the associated object typically has by daylight. The process facilitates the recognition by the vehicle operator of images of traffic scenes recorded outside the visible spectrum.

Abstract: Represented and described is a gas lance (1) made of a fireproof material, having an entry surface (2) and an exit surface (3), having channels (5) having slit-shaped cross-section, which comprise an entry slit (6) and an exit slit (7). In order to provide a gas lance (1) in which the gas exits in such a manner that a good thorough mixing of the melt is achieved and a simple penetration of the melt by the gas is avoided, it is proposed that the projection of the exit slit (7) of a channel (5) onto the entry surface (6) be offset in relation to the entry slit (7) of the channel.

Abstract: The optimum reproduction of high-contrast motifs in digital imaging technology is limited owing to the limited dynamic range of present-day image sensors. The reproduction of high-contrast motifs is intended to be improved using active pixel image sensors. The sensitivity of the sensor pixels is adapted, controlled in an analogous manner to the blurred brightness distribution in the motif, to ensure that the dark and bright image regions of the motif are also reproduced, well illuminated, without any loss of detailed contrast. This results in a particularly natural and balanced image impression. This method may be used in numerous fields for digital image processing.

Abstract: The invention relates to a method for the production of copolymer based on ethylene by continuous copolymerization of ethylene and comonomer in a reactor in the presence of a catalyst. In this method, in a first step of the copolymerization, a mixture comprising ethylene and comonomer of such a composition that a copolymer-containing coating deposits in the reactor is metered into the reactor and/or generated in the reactor, and, in a second step, the concentration of the comonomer in the metered-in mixture and/or in the mixture generated in the reactor is reduced sufficiently and/or the concentration of the ethylene in the metered-in mixture and/or in the mixture generated in the reactor is increased sufficiently that the coating is removed from the reactor either partially or completely. The method has the advantage that the production of copolymer does not have to be interrupted during cleaning of the reactor.

Abstract: A method for electronic reduction of the contrast of video images as early as during recording provides electronic brightening of the shaded zones of a video image in a camera as early as during recording while maintaining the detail contrast even in the brightened regions. A blurred diffuse image of the motif is produced on the image sensor in the camera by the objective and the electronically alterable diffusion element, and is stored in a frame store. The black and white contrast of the mask is determined in the evaluation circuit, and a control variable is generated pixel-by-pixel from this. The focused video image which is subsequently produced on the image sensor when the diffusion element is switch to be crystal-clear is read and is amplified or attenuated pixel-by-pixel such that the shadowed parts are brightened and/or the bright zones are attenuated.

Abstract: The invention relates to a vehicle navigational system with a radar arrangement and an image sensor arrangement. It is proposed to derive target parameters separately from the receiving signals of the two arrangements and to convey them to data merging means to link the separately derived parameters. Linking can be carried out at different levels of digital signal processing.

Abstract: In a process for the production of colour photographic prints, in which transparent colour photographic originals having a wide range of brightness are reproduced on a colour photographic paper and the colour photographic paper exposed in this manner is subjected to a process comprising at least the stages colour development and silver removal, satisfactory definition both in the highlights and in the shadows is achieved by locally modifying the sensitivity of the colour negative paper before processing as a function of the original and with the modification not being sharply defined.
