    • Positioned adjacent to the delivery end of a device for folding sheets delivered from a printing press is a sheet pick up device to intercept a sheet for test purposes. The mechanism to intercept the sheet includes a receiving roller carrying a guide belt which is moved into the delivery path and then transfers the sheet to a second guide belt for holding the test sheet between the two guide belts for delivery to a special delivery means where the sheet can be inspected. The roller is supported on a movable arm which is synchronized with the delivery belt of the folding apparatus, and the guide belts are arranged to move at a speed faster than the delivery belts. The removal of a sheet for test purposes does not interfere with the delivery of the other sheets and operations do not have to be stopped to test a sheet.
    • 定位在用于折叠从印刷机传送的纸张的装置的输送端附近的纸张拾取装置,用于截取用于测试目的的纸张。 拦截片材的机构包括承载导向带的接收辊,该导向带移动到输送路径中,然后将片材转移到用于将测试片材保持在两个导带之间的第二导带,用于传送到特殊的递送装置, 可以检查纸张。 辊子支撑在与折叠装置的输送带同步的可动臂上,并且引导带布置成以比输送带更快的速度移动。 用于测试目的的纸张的移除不会干扰其他纸张的传送,并且不必停止操作来测试纸张。

    • A technique for compression and expansion of a function defined upon an M-dimensional manifold embedded in N-dimensional space uses a second generation wavelet transform and a modified zerotree bit-encoding scheme. Typically, a function is defined upon a two-dimensional manifold embedded in three-dimensional space, such as a sphere. A geometric base is chosen as a coarse initial model of the manifold. Second generation wavelets for the function are calculated using a triangular subdivision scheme in order to subdivide the geometric base in order to produce a refined triangular mesh. The wavelet coefficients are defined at the vertices of the triangles in the triangular mesh. A tree structure is created in which each node of the tree structure represents an associated triangle of the triangular mesh. Each triangle in the mesh is recursively subdivided into four subtriangles and each associated node in the tree structure also has four children, which correspond to the four subtriangles. Each wavelet coefficient defined at a particular vertex in the triangular mesh is uniquely assigned to a single one of the triangles at a next higher level of subdivision, such that each triangle at the next higher level of subdivision has from zero to three assigned wavelet coefficients. Using a modified zerotree encoding scheme, values of the wavelet coefficients are processed bit plane by bit plane, outputting bits indicative of significant nodes and their descendants. Sign bits and data bits are also output. An expansion technique inputs bits according to the modified zerotree scheme into the tree structure in order to define wavelet coefficients. An inverse second generation wavelet transform is used to synthesize the original function from the wavelet coefficients.
    • 用于压缩和扩展在嵌入在N维空间中的M维多维流形体定义的函数的技术使用第二代小波变换和修改的零树比特编码方案。 通常,在嵌入在三维空间中的二维歧管(例如球体)上定义功能。 选择几何基础作为歧管的粗略初始模型。 使用三角形细分方案计算功能的第二代小波,以便细分几何基,以产生精细的三角形网格。 小波系数定义在三角形网格中三角形的顶点。 创建树结构,其中树结构的每个节点表示三角形网格的相关三角形。 网格中的每个三角形递归地细分为四个子三角形,并且树结构中的每个相关节点也具有四个子对象,其对应于四个子对角。 在三角形网格中的特定顶点处定义的每个小波系数被唯一地分配给下一个更高级别的细分中的单个三角形,使得下一个更高级别的细分中的每个三角形具有从零到三个分配的小波系数。 使用修改的零树编码方案,小波系数的值按位平面逐位处理,输出指示重要节点及其后代的比特。 同时输出符号位和数据位。 扩展技术根据修改的零树方案将比特输入到树结构中,以便定义小波系数。 使用逆第二代小波变换来从小波系数合成原始函数。
