Abstract: An image compression system for compound images containing both text and pictures. The system is capable of receiving the images on a non-overlapping 8 by 8 pixel blank basis and includes a discrete cosine transformer connected to a quantizer drawing lossy quantization factors from quantization tables. The lossy quantization factors are modified by a variable quantization subsystem based on the frequency of changes in the block to provide low lossy quantization factors for high frequency of changes and high lossy quantization factors for low frequency of changes. The high frequency of changes being indicative of text and the low frequency of changes being indicative of pictures. The quantizer is connected to an entropy coder using lossless entropy encoding factors from Huffman tables to provide JPEG compliant files.

Abstract: A process for controlling the remote installation of a software package within a remote PC client existing on a LAN. An executable file is arranged for the purpose of controlling the local setup procedure within the remote PC client. The executable file is a windows NT service and is installed in accordance with rules of the NT Service Control Manager. The executable file is further associated with a description file (package.ini) which is also stored on a shared resource, and an option on the command line of the executable file refers to that description package. Once the executable file has been installed as a service, the NT SCM can be used for starting it and, therefore, for triggering the remote installation of the software package within the PC client using the information found in the description file. The process can also be used for remotely triggering an executable file which is arranged as a NT service, and installed by the NT SCM.

Abstract: A photoelectric imaging device is disclosed in which the object to be imaged is illuminated by light from an external light source, such as a video display. Use of an external light source eliminates the need for a light source and its accompanying power supply to be located within the photoelectric imaging device. The portability of the photoelectric imaging device is thus enhanced. When a video display is used as the external light source, an external computer, to which the video display may be attached, may accomplish the processing required for imaging. This allows further reduction in the size, weight, complexity and cost of the photoelectric imaging device by eliminating the need for a processor and a data storage device to be located within the photoelectric imaging device.

Abstract: A method and apparatus for processing primitives in a computer graphics display system. The apparatus comprises a graphics device which receives commands and data from a host computer of the computer graphics display system. The data includes clip coordinates which are perspective projected by the graphics device into window coordinates. The host computer of the computer graphics display system is programmed to execute a geometry processing pipeline which transforms object coordinates associated with a primitive into clip coordinates which are then delivered to the graphics device. The graphics device then performs perspective projection on the clip coordinates to transform the clip coordinates into window coordinates. In accordance with the preferred embodiment of the present invention, the geometry processing pipeline being executed by the host computer performs a transformation which transforms the object coordinates into window clip coordinates and then delivers the window clip coordinates to the graphics device. The graphics device then performs perspective projection on the window clip coordinates to transform them into window coordinates. In accordance with an alternative embodiment of the present invention, the geometry processing pipeline being executed in the host computer performs a transformation which transforms the object coordinates into eye coordinates and then transforms the eye coordinates into clip coordinates. The clip coordinates are then delivered to the graphics device, which transforms the clip coordinates into window coordinates.

Abstract: A configuration tracking system for a call detail record (CDR) filtering system keeps track of the contexts under which CDRs are collected and filtered. The configuration tracking system is useful in a multiple concurrent filtering paradigm, in which several CDR filters may be active at any given time and the filter criteria are dynamically altered. Filter criteria for multiple filters are recorded in a dynamically changing table. The configuration tracking system maintains a historical record of the filter criteria in the dynamically changing table. The configuration tracking system updates its historical record by detecting changes in the dynamically changing filter table, comparing earlier and later versions of the table, and opening and/or closing timestamped filter records in response.

Abstract: A method and apparatus is described for detection and deterrence of counterfeiting that permits one to make legitimate color copies without introducing visual artifacts or experiencing substantial processing delays. The scheme detects a characteristic color of frequently counterfeited documents and alters the characteristic color in the copies. The scheme exploits the fact that conversion between color spaces is frequently accomplished using a color Look-Up Table (LUT). Because it represents no computational burden to alter the values in the LUT, we can efficiently modulate slightly the value of the characteristic color in a way that depends on the value of the counter. For example, at first even banknote green is rendered correctly. However, as the page uses more and more of the ink, a modulation function causes conversion to a darker value than the actual green requested. After using a significant portion of the ink required to render a banknote, the modulation function can switch again, and cause a lighter than requested green to be returned. The net effect of using this modulation function is that distinct bands will appear when an image of a banknote is printed. These visible marks appear on the page independently of the orientation of the note. If we consider a general image with a lot of green, we find that there is no visible difference between versions of the image rendered with and without the modulation scheme. The reason for this is that although many pixels of the general image may meet the criterion of being classified as nullbanknote greennull in the LUT, they are dispersed and a minor increase or decrease in the value is not as noticeable as when a large amount of that ink is used in close proximity, as is the case on the back of a banknote.

Abstract translation: 描述了一种用于检测和威慑伪造的方法和装置，其允许在不引入视觉伪影或经历实质的处理延迟的情况下进行合法的彩色副本。 该方案检测经常伪造的文件的特征颜色，并改变副本中的特征颜色。 该方案利用了颜色空间之间的转换通常使用颜色查找表（LUT）来完成的事实。 因为它不代表改变LUT中的值的计算负担，所以我们可以以取决于计数器的值的方式有效地调制特征颜色的值。 例如，首先，正确地渲染纸币绿色。 然而，当页面使用越来越多的墨水时，调制功能使转换成比所请求的实际绿色更暗的值。 在使用大量部分所需的油墨来形成纸币之后，调制功能可以再次切换，并使得比要求的绿色更亮。 使用该调制功能的净效果是当打印钞票的图像时将出现不同的频带。 这些可见标记出现在页面上，而与注释的方向无关。 如果我们考虑大量绿色的一般图像，我们发现在使用和不使用调制方案的情况下，图像的版本之间没有明显的区别。 其原因在于，虽然普通图像的许多像素可能符合LUT中被分类为“纸币绿”的标准，但它们是分散的，并且该值的小幅增加或减小不如当大量 该油墨的使用非常接近，如纸币背面的情况。

Abstract: An electro optic display (10) provides an electrode configuration adjacent each pixel which allows a non-uniform electrical field to be applied across the pixel (22) so that the optical output varies in the direction transverse to the pixel thickness. This allows only part of the pixel to be turned ON, or for shading within the pixel, depending on the characteristics of the electro-optic material. In a preferred embodiment the row and column electrodes (14, 17) are each made up of a group of conductive tracks (12, 18) connected into groups by impedance elements (13, 19). Voltage ramps are applied across the electrodes via input electrodes 15 and 20. A multiphase drive scheme is described for ferro-electric and similar materials in which a number of different voltage ramps are applied to a row in succession, and at each phase the appropriate ramps are applied simultaneously to the column electrodes to build up the required pixel shape over a number of phases.

The contents of each of the processable sub-image files are stitched into a blank text document by applying logical operators to the data in the files to produce a complete composite text document containing data indicative of the textual content of the scanned document.
