    • An open-end wrench is capable of locking and unlocking a hexagon nut continuously and contains: a holder, a driving head, a returning spring, and a handle. The holder is configured to accommodate the driving head, the returning spring, and an actuation shaft. The holder includes a first jaw, a body, and an accommodation cavity, wherein the accommodation cavity has a first panel, the holder further includes a first orifice for accommodating a first post, a second orifice for housing a second post, and a third orifice for accommodating a third post. The driving head includes a second jaw and an extension which has a second panel, a slot, a trench, and a projection. The returning spring is accommodated in the slot, and the handle includes the actuation shaft, an operation shaft, a concaved portion, and a coupling hole.

    • A method for authenticating a printed document which carries barcode that encode authentication data, including word bounding boxes for each word in the original document image and data for reconstructing the original image. The printed document is scanned to generate a target document image, which is then segmented into text words. The word bounding boxes of the original and target document images are used to align the target document image. Then, each word in the original document image is compared to corresponding words in the target document image using word difference map and Hausdorff distance between them. Symbols of the original document image are further compared to corresponding symbols in the target document image using feature comparison, symbol difference map and Hausdorff distance comparison, and point matching. These various comparison results can identify alterations in the target document with respect to the original document, which can be visualized.
    • 一种用于验证携带条形码的打印文件的方法,该打印文件对原始文档图像中的每个单词和用于重建原始图像的数据进行编码的认证数据,包括字边界框。 扫描打印的文档以生成目标文档图像,然后将其分割成文本字。 使用原始和目标文档图像的边界框对齐目标文档图像。 然后,将原始文档图像中的每个单词与目标文档图像中的相应单词进行比较,使用单词差异图和它们之间的Hausdorff距离。 使用特征比较,符号差异图和Hausdorff距离比较以及点匹配,将原始文档图像的符号进一步与目标文档图像中的对应符号进行比较。 这些各种比较结果可以识别目标文档中关于原始文档的变化,这可以被可视化。
