Abstract: A method and apparatus for recognizing characters in pixel image data and for forming a text file of the characters. Pixel image data is inputted and, if the pixel image data is not binary image data then the pixel image data is converted into binary pixel image data. Blocks of pixel image data are selected by outlining contours of connected components in the pixel image data, determining whether the outlined connected components include text unit or non-text units based on the size of the outlined connected components, selectively connecting text units widthwisely to form text lines based on proximity of adjacent text units, and selectively connecting text lines vertically to form text blocks based on proximity of adjacent text lines and on the position of non-text units between text lines. A hierarchical tree is formed based on the outlined connected components. Text blocks are segmented into text lines of pixel data by adaptively dividing the text blocks into at least one column based on a horizontal projection of pixel density across the column, and characters are cut from the segmented lines in two cutting steps in which the first cutting step cuts between non-touching and non-overlapping characters and the second cutting step cuts between touching characters. The cut characters are recognized and character codes are derived based on such recognition. The character codes are stored in a computer text file in accordance with the order established by the hierarchical tree. If desired, the non-text units may be interspersed with the stored character codes in accordance with the order established by the hierarchical tree. The pixel image data may be pre-processed by, for example, image compression or image enhancement, and the recognized characters may be subjected to post-processing, for example, context checking. Designators may be appended to non-text units based on characteristics of the non-text units. For example, white contour tracing may be employed on the interior of non-text units, non-grid-arranged white contours may be recombined, and the fill rate of the white contours may be calculated, and table designators appended to the non-text unit based on the number of white contours or the recombination rate of non-grid-arranged white contours or the fill rate of white contours. Cutting between non-touching and non-overlapping characters may be accomplished by sparsely stepping through the line segment, and cutting between touching characters may be accomplished in accordance with whether information concerning the spacing between touching characters is known. If information concerning the spacing is known, then cutting may be accomplished based on the spacing statistics. If information is not known, then cutting between touching characters may be accomplished in accordance with rotated projections of pixel density so as to make an oblique cut through the touching characters at an angle and position determined by the rotated projection. Inadvertently characters may be recombined.

Abstract: The invention is a communication method with the equipment belonging to it and its aim is to increase the number of users in a network or cell. Data is transmitted by the method by using a combined CDMA/TDMA or TDMA/CDMA multiple use whereby complementary code sets (complete orthogonal codes or non-interacting codes) are used as spreading codes. In the applications of the method to existing or planned TDMA systems, a CDMA part is added to them, by which a spreading coded CDMA multiple access is used in every time slot of the TDMA frame, in said way, to increase the number of users. The described method does not require any power control methods, nor any multiple access interference cancelling methods to increase network or cell capacity.

Abstract: An automated paint-batching system for producing paint cans of any size and color. The system includes a plurality of paint-batching cells, with each cell having a machine comprised of either one or two dispensing stations (16, 18). When two dispensing stations are used, the two dispensing stations are: A first tint-station (16), where a small volumetric dispensing of the base, water-base or oil-base, of the paint is dispensed, in order to wet the bottom of the can, at which first station, thereafter, is dispensed all of the liquid colorants making up the formula of the paint can, and a second base-dispensing station (18) at which the remainder of the base of the formula of the paint is dispensed. Each of the first and second stations of the paint-batching machine of the invention has operatively associated therewith a weighing mechanism (70) upon which rests the paint can during the dispensing at the respective station used in quality-control weighing of each dispensing. When only one dispensing station is used, all of the above-steps are performed at the one station. Each paint can has attached to it a bar-code label which represents a relocatable memory-address of the computer which stores the color-formula from that can and other information. The computer operating system controls the guidance of the particular paint can along its conveyance, so that the paint can is designated to one of a plurality of paint-batching cells of the system of the invention, with the bar-code of the paint can being read at a plurality of stations along the entire manufacturing process.
