Abstract: There is provided a method (100) for performing data capture in an unlabelled document based on a labelled document, wherein the labelled document contains one or more elements each labelled with respect to a field. The method comprises: determining (S110) one or more anchors, wherein an anchor comprises a pair of points that match between the labelled document and the unlabelled document; generating (S120) an overall kernel using the determined one or more anchors; and identifying (S130), using the overall kernel in a kernel machine, one or more elements to be captured in the unlabelled document, wherein the one or more elements to be captured correspond in field to the one or more labelled elements contained in the labelled document.

Abstract: The invention provides a method of characterizing a scattering colored pigment for use in the determination of the absorption and scattering coefficients of the scattering colored pigment, the method comprising the step of obtaining a reflectance spectrum of a mixture of the scattering colored pigment with a substantially non-absorbing scattering pigment at a plurality of different volume fractions wherein the substantially non-absorbing scattering pigment has a particle size greater than 0.6 micron. Also provided is a pigment characterization system adapted to perform the method of the invention to characterize a scattering colored pigment.

Abstract: A modular component connector substrate assembly for mounting thereon of at least one fluid control component, the assembly including at least two substrate blocks or one substrate block and an end block, all in fluid communication with each other via internal passages, with a separate fluid pressure connector fluidically interconnecting and fixedly spacing adjacent ones the substrate blocks and/or end blocks with adjacent substrate blocks, wherein the conduits connected by the pressure connector all being located in a common internal plane and thus being capable of extending in any of the compass directions (N,S,E,W) within this common plane. The bottom surfaces of the substrate and end plates abut mounting plates configured to the existing ANSI/ISA SP76 specification.

Abstract: A method of generating halftone output on an output device. The method includes retrieving at least one table which associates gray levels with halftone results for a region of an output frame including more than one pixel, determining a reference gray level for a tile of an output frame including more than one pixel, using the at least one table to determine a halftone result for the reference gray level, storing the halftone result for the reference gray level to the tile of the output frame, and delivering the output frame to the output device. The table may be generated from a set of thresholds, which may be a threshold array. A first table may associates gray levels with codes and a second table may associates codes with halftone results, and the method may include converting the reference gray level to a reference code with the first table and converting the reference code to the halftone result for the reference gray level with the second table.

Abstract: A page printer uses alternative internal representations for the print data in each of multiple lateral strips that make up the page. Page description language input is converted to an intermediate display list format that is sorted into display commands associated with each strip. If during input the display list representation of the data fills the memory allotted to its storage, one or more of the strips is converted from display list format to raster format and compressed using a lossless compression algorithm. If storage of compressed strips subsequently exceeds available memory, raster data is further compressed using a lossy compression algorithm. Additional display list commands are rasterized by decompressing the compressed strips, processing the new commands and recompressing the data using lossless or lossy compression as required. If the display list does not overflow memory during input, the complete strips are rasterized and compressed one at a time in the order in which they will be printed.

Abstract: A multipoint polling system wherein a multipoint switch selectively connects a plurality of remote terminals to a central station in response to remote terminal addresses transmitted on a signaling path to the multipoint switch. Polling apparatus stores portions of a remote terminal address list provided by the central station and transmits individual ones of the stored remote terminal addresses on to the signaling path. The polling apparatus periodically requests different portions of the remote terminal address list and replaces the stored remote terminal address portion with the requested remote terminal address portion.The multipoint switch is advantageously comprised of a plurality of sections with each section of the switch responsive to a portion of the address list for establishing a signaling path between the central station and selected ones of the remote terminals defined by the address list portions.
