    • Apparatus is provided for transporting a sheet in a predetermined path of travel. The apparatus comprises a plate having a lower surface extending parallel to and defining the path of travel, and having an aperture formed therein. In addition, the apparatus comprises sheet feeding structure, including a first pair of rollers spaced apart from one another and an endless belt looped about the first rollers, wherein the belt has a lower belt run extending between the first rollers and beneath the plate. Further, the feeding structure includes instrumentalities for driving one of the first rollers for moving the lower belt run at a constant velocity in the direction of the path of travel. Moreover, the feeding structure includes a second pair of rollers which are disposed beneath the plate and are made of a compliant material. Still further, the feeding structure includes structure for resiliently urging the compliant rollers toward the path of travel for urging a sheet feed to the apparatus into contact with the belt and the lower surface of the plate, whereby the belt engages and feeds the sheet at a constant velocity with a portion thereof in the path of travel when fed past the aperture.

    • Method and apparatus is disclosed for automatically processing visual images electronically so as to permit intelligent machine analysis of the image content. A special distributed logic system architecture facilitates rapid real time image analysis and the production of reaction control signals in a high speed production line environment, for example. Dedicated decision logic is employed to determine in but a single micro-instruction cycle whether a detected corner point of the image should be linked to another already linked chain of such corner points so as to define part of a closed edge contour of the image under examination. This ability to so rapidly classify encoded corner points as either belonging or not belonging to a given set of such corner points which describe a closed edge contour is quite useful in achieving rapid real time image analysis capability. Special dedicated data address indexing circuitry is also employed for most expeditiously retrieving successive address linked data words from a data memory in successive single micro-instruction cycles as required to take full advantage of the high speed dedicated corner point matching circuitry. The dedicated data memory indexing circuitry is provided in addition to the usual program instruction indexing circuitry employed in connection with the instruction register of the associated data processing system.
    • 公开了用于以电子方式自动处理视觉图像以允许智能机器分析图像内容的方法和装置。 特殊的分布式逻辑系统架构例如可以在高速生产线环境中促进快速实时图像分析和反应控制信号的生成。 采用专用决策逻辑来确定单个微指令周期中图像的检测角点是否应连接到另一个已连接的这些角点的链,以便定义被检查图像的封闭边缘轮廓的一部分 。 将编码角点这样快速分类为属于或不归属于描述封闭边缘轮廓的给定的一组这样的角点的能力对于实现快速实时图像分析能力是非常有用的。 还采用特殊的专用数据地址索引电路,以便在连续的单个微指令周期中最快速地从数据存储器中检索连续的地址链接的数据字,以便充分利用高速专用角点匹配电路。 除了与相关联的数据处理系统的指令寄存器结合使用的常规程序指令索引电路之外,还提供了专用数据存储器索引电路。
