摘要： A sensor system for measuring physical properties of a sheet. In one embodiment, the sensor system measures paper curl and thickness using two sensors, each of which includes a member, a base, and measurement circuit. The two members are positioned in opposition to each other and both contact the sheet as it passes between them. Each member is coupled to a base, which includes a measurement circuit. Each measurement circuit measures the displacement of its associated member. In another embodiment, the sensor system measures stiffness and curl using two pairs of opposed sensors. In yet another embodiment, the sensor system measures thermal diffusivity of a sheet of paper using three sensors, one of which includes a heater for heating the sheet of paper and the other two sensors include thermocouples in contact with the sheet of paper for sensing the heat of the paper.

摘要： A processor is provided with first and second document images. The first image represents an instance of a reference document to which instance a mark has been added. The second image is selected from among a collection of document images and represents the reference document without the mark. The processor automatically extracts from the first document image a set of pixels representing the mark. This is done by performing a reference-based mark extraction technique in which the second document image serves as a reference image and in which substantially the entirety of the first document image is compared with substantially the entirety of the second document image. Also, the processor is provided with information about a set of active elements of the reference document. The reference document has at least one such active element and each active element is associated with at least one action. The processor interprets the extracted set of pixels representing the mark by determining whether the mark indicates any of the active elements of the reference document. If the mark indicates an active element, the processor facilitates the action with which the indicated active element is associated.

摘要： A method and system provide for searching and matching gesture-based data such as handwriting without performing a recognition process on the handwritten gesture data to convert it to a standard computer-coded form. Target data collected as sample data points of spatial coordinates over time are concatenated into a single target gesture sequence of sample data points. The sample data points comprising the gesture-based data structure to be searched (the corpus) are grouped into corpus gesture sequences for matching against the target gesture sequence. Matching may be done by any suitable method, and a novel signal comparison technique based on dynamic time warping concepts is illustrated. The result of the matching is a list of the locations of the matching corpus gesture sequences in the corpus, which in turn may be used for further processing, such as the display of an image of the matching corpus gestures for a system user. The ability to determine the existence and location of a gesture in the corpus that matches a target gesture is the basis for performing a variety of additional functions, such as a "find and replace" function and the ability to use gestures as keywords to index a gesture-based data structure without performing recognition on either the keyword gestures or the gesture-based data structure. The technique is suitable for inclusion in any system that accepts gesture-based data, such as a personal digital assistant (PDA) or other pen-based computing device.
摘要翻译：一种方法和系统提供用于搜索和匹配基于手势的数据，例如手写，而不对手写手势数据执行识别处理，以将其转换为标准计算机编码形式。作为时间空间坐标的样本数据点收集的目标数据被连接到样本数据点的单个目标手势序列中。包括要搜索的基于手势的数据结构（语料库）的样本数据点被分组成用于与目标手势序列匹配的语料库手势序列。可以通过任何合适的方法进行匹配，并且示出了基于动态时间扭曲概念的新颖的信号比较技术。匹配的结果是语料库中匹配的语料库手势序列的位置的列表，其又可以用于进一步处理，例如系统用户的匹配语料库手势的图像的显示。确定与目标手势匹配的语料库中的手势的存在和位置的能力是执行各种附加功能的基础，诸如“查找和替换”功能以及使用手势作为关键词对索引进行索引的能力基于手势的数据结构，而不对关键字手势或基于手势的数据结构进行识别。该技术适于包括在接受基于手势的数据的任何系统中，例如个人数字助理（PDA）或其他基于笔的计算设备。

摘要： Binary digital data is rendered on a surface, such as a sheet of paper, by printing a series of color patches on the sheet, with the 1 bits rendered as color patches of a first color and the 0 bits rendered as color patches of the second color. The color patches are arranged in a predetermined order along an axis on the surface. The second color relates to the first color by a fixed relationship in color space, whereby the absolute values of the first and second colors are immaterial to a detecting apparatus. The color patches can be intermixed with areas of a third color, the third color representing an average in color space of the first color and the second color.

摘要： A system and method for receiving, analyzing, and managing key information extracted from input documents in multiple document genres. A document “genre” is the social environment that defines the document's expected structure and content. Information is extracted from the input documents based on their genre, and is synthesized into a distributed genre document, or database, representing all extracted information from all input documents. An output document having a selected genre is created by assembling information from the database consistent with the selected genre.

摘要： A system and method for extracting key information from digitized audio messages, including telephone voice messages. Information, such as a telephone number and the name of the caller, is derived and extracted from a voice message and used to establish links to the information within the message. The telephone number and name of the caller can then be replayed without the need to replay the entire voice message. The telephone number and name of the caller can also be used as indices into an information database.

摘要： This technique for determining an optimal color space direction for a respective input color mathematically models the determination of the color space direction as an optimization problem and uses models of human perception and scanner response that produce quantitative measurements of color changes. A given input color and a direction in color space away from the givien input color define a color change away from the input color. An objective function simultaneously minimizes the quantitative color difference of the color change measured by a human perception model and maximizes the color response difference of a scanner response model to find an optimal color space direction for the respective input color.
