摘要： An input carrier sheet 12C for document distribution system 10 carries input symbols hand entered by the user into pre-existing constraint grids 12. The constraint grids may be printed in continuous tone or halftone. The print only partially covers the underlying carrier, permitting the exposed carrier to reflect light. The grids have sufficient pigment to be visible to the user, but insufficient pigment to form foreground pixels along with the hand-entered stroke when detected during the scanning. The signal (symbol)-to-noise (carrier) ratio is enhanced by reducing the pigment content of the constraint grids which increases the reflectivity of the grids. The S/N may be further enhanced by placing the strokes of the hand-entered symbols on top of the grid which occults some of the grid pigment. The S/N is further enhanced by highly reflective brightening agents in the grid print, and by aperture effect during scanning.

摘要： An OCR system 10 classifies an input image vector of an unclassified symbol with respect to a library 14T of template image vectors of pre-classified characters. Each template vector is in the form of a sequence of elements representing the image intensity level of a pixel within the character defined by that template vector. Each template element is part of the image background, foreground, or transition ground between the background and foreground. Each input vector, like the template vectors, is also in the form of a sequence of elements. However, in the input vector, each element represents the sum or an image intensity level signal component defining the symbol within the image of the unclassified symbol plus a greyscale noise component. Each input element is also part of the background, foreground, or transition ground. The input vector and at least one of the template vectors are entered into a classifier device 18. The input vector is classified based on the backgrounds, foregrounds, and transition grounds. The presence of transition ground in the input vector and the template vector produces a robust classification response with a more uniform correlation coefficient between repeated classifications of the same input symbol. The classifier device may be a distance function classifier or a neural network classifier.

摘要： Task order system 10 dispatches task orders throughout user network 10N concerning user record documents. Task order 10T is carried on an input medium suitable for scanning such as ordinary paper, and specifies both the dispatch task and the record document. The task order contains an input task identification (ID) 22 and record document index symbols 24. Scanner 10S receives the input medium and scans the task order thereon to obtain pixel images of the input ID and the index symbols. Classifier 10C receives the pixel images from the scanner for classification into an input ID code, and index codes. Template library 10L has a task ID template which defines the corresponding each task ID. Selector 11S selects the template code which matches the input ID code. Display device 10D notifies the user if the selection was unsuccessful. The user may correct the input ID code or manually select a template code from user keys 10K. Dispatcher 16D is responsive to the selected template code for dispatching the task order. Input cross-check symbols 24C and input digit count number 24D may be employed to verify that the scanning and classifying were accurately performed.

摘要： Stroke-based symbols such as conventional alpha-numerics are formed by individual strokes. Each stroke has intersections or node regions common to two or more strokes and main inter-node body regions unique to a single stroke. Strokes are a primary recognition cue to the human eye and for OCR techniques. The length and orientation of each stroke is determined and entered into a library of extracted strokes for analysis and matching. After selection each stroke is physically cut from the stroke based symbol to assist in selecting the next stroke. The body regions are cut first. The common node regions are temporarily protected to preserve the end nodes of the remaining strokes. Each node is cut during the extraction sequence of the last stroke common to that node. This sequential removal of strokes results in a progressively diminishing symbol residue and a progressively increasing library of extracted strokes.

摘要： An arbitrary number of member computer stations are inter-connected by a "party" communication network. Each member station is normally in a high impedance Monitor Mode, for monitoring in-coming messages. The incoming messages latch the monitoring stations into a Receive Only Mode for preventing "interrupts" of on-going communications. Each station continuously monitors the input impedance from the network, to determine when the network is available for transmission. Member stations may enter the low impedance Transmit Mode only when the network is available, because all of the other stations are in the Monitor Mode. A high Z from the network indicates to each station that the network is available. A low Z indicates that another station is in the transmit Mode, and is in control of the network. The random entry of two (or more) parties at the same time is resolved by a Pre-Transmission Test Cycle. Full transmit status with actual data transmission, cannot be obtained unless the Test code transmission reveals a high network impedance indicating that the network is available. In the "two-party" start situation, each party senses the other parties low Transmit Mode impedance. Both parties drop back to the Monitor Mode, and a data "collision" is avoided.

摘要翻译： 任意数量的成员计算机站由“派对”通信网络互连。 每个成员站通常处于高阻抗监视模式，用于监视即将发送的消息。 传入的消息将监控站锁定到仅接收模式，以防止正在进行的通信的“中断”。 每个站持续监控来自网络的输入阻抗，以确定网络何时可用于传输。 只有当网络可用时，会员站才能进入低阻抗发射模式，因为所有其他电台都处于监视模式。 来自网络的高Z向每个站指示网络可用。 低Z表示另一个站处于发送模式，并且在网络的控制中。 两个（或多个）方在同一时间的随机进入通过预传输测试周期来解决。 完全发送状态与实际数据传输不能获得，除非测试代码传输显示高网络阻抗指示网络可用。 在“双方”启动的情况下，各方感觉对方低传输模式阻抗。 双方回到监控模式，避免数据“碰撞”。

摘要： The self-healing system comprises a self-healing processor and an error mitigation system. The self-healing processor includes a code block associated with the operation of a portion of digital logic. The self-healing processor also includes a dynamic signature analysis circuit. The processor executes the code block. The dynamic signature analysis circuit creates a dynamic signature representing the operation of the portion of digital logic associated with the code block. The error mitigation system receives the dynamic signature from the dynamic signature analysis circuit. The error mitigation system compares the dynamic signature to a static signature to determine if the signatures match. If the signatures do not match, then the digital logic associated with the code block has an error. The error mitigation system retries execution of the code block. The error mitigation system stores log information describing the above events.

摘要： A radiographic imaging system (100) comprises an X-ray tube (110), a sensor plate (120), and a graphics engine (130). The tube (110) and the sensor plate (120) rotate synchronously about a patient (150) and expose a stereoscopic pair of images which are transmitted to the graphics engine (130). The graphics engine (130) determines (312) the geometry of the system (100). If (314) the pair of images are toed-in relative to each other, the graphics engine (130) converts (316) the images into a parallel geometry. Likewise, the graphics engine (130) also processes (320) the images for keystone distortion, if necessary. Simply flipping the images in the stereo pair distorts the depth of objects in the stereoscopic image. Instead of simply flipping the images, it is desirable to “go behind” the screen (412A) and look at the image from the back. In order to produce a stereoscopic image having this viewpoint, the graphics engine (130) uses the geometry of the radiographic system (100) to adjust (324) the screen parallax of the image after the constituent images are flipped (322) and provide the desired three-dimensional perspective.

摘要： Cameras (10, 12) produce first and second images (14, 16) of an object (18) from different viewpoints. An image partitioning module (54) partitions the images (14, 16) into a plurality of vertically striped regions (70), such that each region (70) of the first image (14) corresponds to a region (70) of the second image (16). A region alignment module (55) vertically shifts a region (70) of the first image (14) in a direction calculated to vertically align a portion (30) of the region (70) with a substantially matching portion (32) of the corresponding region (70). A disparity calculation module (62) calculates at least one disparity value between at least a portion (30) of the vertically shifted region (70) and at least a portion (32) of the corresponding region (70).
