    • Disclosed is a method for counterfeit-proof of documents bearing a picture. The picture is transferred into a digital image file or present as a digital image file into which a binary form secret image present is incorporated. The digital image file is divided into cells of a number equaling a number of pixels of the secret image. A parameter function allocates a binary output value to each cell on the basis of parameter values, which describe each image point, in such a manner that the bivalent output value of all the cells yields a bivalent position matrix, by the parameter values of the image points of the individual cells being modified with the aid of an optimizing process in such a manner that, first, the changes made to the image file of the picture of the document result in no visually perceivable changes and, second, the result of applying the parameter function to the individual cells yields a bivalent position matrix which corresponds to the binary values of the secret image.
    • 公开了一种用于防伪图像的文件的方法。 图像被转移到数字图像文件中或呈现为数字图像文件,其中并入了存在二进制形式的秘密图像。 数字图像文件被划分成等于秘密图像的像素数的数字的单元。 参数函数基于参数值分配二进制输出值,该参数值描述每个图像点,以使得所有单元的二价输出值产生二值位置矩阵,由图像的参数值 借助于优化处理,各个单元的点被修改,使得首先,对文档的图像的图像文件进行的改变导致没有视觉上可察觉的改变,第二,应用 对于各个单元的参数函数产生对应于秘密图像的二进制值的二价位置矩阵。

    • A slatted sunroof for a motor vehicle has slats that are lifted and spaced apart at intervals from one another when the roof is open, and in particular are pushed against one another so that their spacing is reduced by contrast with their closed position. A roof liner that is deformable extends, at least when the roof is closed, in an area located below the slats. Fasteners are provided that hold the roof liner against the slats at locations that are regularly spaced and produce an orderly pattern when the roof is opened, especially in the displacement direction of the slats. The sunroof is designed in such fashion that undesired folding of the roof liner because of different degrees of thermal expansion of the roof liner and the slats is prevented. This is accomplished by the fasteners each comprising a retaining element on the slat side and a retaining element on the roof liner side, the retaining elements being connected movably with one another, with the retaining elements on the slat side being fastened to the slats and the retaining elements on the roof liner side being fastened to the roof liner.
    • 用于机动车辆的板条天窗具有当屋顶打开时彼此间隔地间隔开的板条,并且特别是彼此推压,使得它们的间隔与其关闭位置相反地减小。 至少当屋顶关闭时,可变形的屋顶衬板在位于板条下方的区域中延伸。 提供了紧固件,其将屋顶衬套抵靠在板条上的位置,该位置在屋顶被打开时,特别是在板条的位移方向上,这些位置是规则间隔开的并且产生有序的图案。 天窗的设计使得屋顶衬板和板条的不同程度的热膨胀不希望地折叠屋顶衬里。 这通过紧固件实现,每个紧固件包括在板条侧上的保持元件和顶板衬里侧上的保持元件,保持元件彼此可移动地连接,板条侧上的保持元件紧固到板条上,并且 屋顶衬里侧上的保持元件紧固到屋顶衬里。
