Abstract: The hierarchy of the hyphenation points in a word is considered and the amount of space remaining in the line where the hyphenated word is to fit is determined, thus selecting the best hyphenation point for the word. Instead of selecting the last possible hyphen within the hot zone, the hot zone is scanned to find hyphenation points that may be better than the last hyphen within the hot zone. The higher a hyphenation point is in the hierarchy, the more preferred is the hyphen.

Abstract: A data processing system and method are disclosed for editing a text document stored as an alphanumeric string of structured document text and displayed as WYSIWYG text. The invention enables changing emphasis characteristics of a marked area of the WYSIWYG text located within a parent structure of the document. The method displays an emphasis menu of the valid emphasis types for the particular parent structure, indicating which ones of the emphasis types are present in the marked area. The method enables deleting an emphasis type from the marked area and will then remove the displayed present indication in the emphasis menu corresponding to the emphasis type deleted from the marked area. The method also enables adding an emphasis type to the marked area and will then display a present indication in the emphasis menu corresponding to the emphasis type added to the marked area.

Abstract: A data processing system, method and program are disclosed to optimize mail piece sorting and the mapping of mail down to the carrier walk sequence using real time statistical data. The invention makes use of techniques such as fast OCR devices at a sending location or deferred processing of OCR scanned mail, to accumulate volume statistics indicating the number of mail pieces being routed particular addressees at a destination postal region on a given day. The information for mail volumes being directed to a particular postal region are collected over data communications links prior to the receipt of the actual mail pieces. The efficiency of sorting is maximized at the destination postal region by organizing the sorting apparatus to remove the highest volume addressee's mail first. This requires the compilation of the real time volume statistics from all of the sending postal regions sending mail to the destination postal location.

Abstract: A method is described for manipulating commonly used elements within a structured document. The method takes advantage of a user's intent in selecting certain keystrokes to complete a task. By making assumptions on the user's intent at the current position within the document and dynamically changing the functions of keystrokes based on those assumptions, the method allows the user to quickly and easily manipulate the commonly used elements of a structured document without having to specify any tag names or markup language, and without having to understand the rules for creating a structured document.

Abstract: A data processing system edits a text document stored as at least one alphanumeric string of structured document text and displayed as WYSIWYG (What You See Is What You Get) text. Look characteristics are controlled for a child document element of the text located within a parent document element of the text. The method performs the step of constructing a child resolved look data set necessary to specify a WYSIWYG appearance of the child element by first accessing modified look value customized by the user for first look parameters and accessing defined look values standardized for second look parameters. For those look parameters which are not customized by the user or which are not defined as standard values for the child element, the values are inherited by the child element from the parent element.

Abstract: The present invention reduces overhead processing of a data processing system by storing a predetermined number of points corresponding to the position of a pointing device as it moves on a workpad or other touch sensitive input device. A predetermined number of points are stored in a buffer, wherein the predetermined number is dependent upon the type of pointing device (e.g., finger, stylus, etc.) used with the workpad. The stored points are periodically displayed or inked on a visual display at a rate of at least 20 times per second. As a result, the user moving the pointing device receives both tactile and visual feedback information similar to that provided by a pencil used to make markings on a piece of paper. An alternative embodiment provides a similar reduction of overhead associated with erasing graphical information displayed on the visual display.

Abstract: A system-wide data stream compatibility is provided for a FAX server in an image archiving system, by the concealment of FAX cover sheet and distribution list object handling information, which is uniquely required by the FAX server, in an otherwise unneeded document descriptor field located outside of the data stream boundary, in the distribution service or session header. In addition, the FAX server provides for the storage of multiple cover sheets and addressee distribution lists which are editable. The FAX server can manage multiple transmissions of FAX messages with customized cover sheets, to multiple addressees in the distribution lists.

Abstract: A computer apparatus, program and method function in a data processing system to replicate a cryptographic facility. The system includes a first cryptographic facility containing a portable part which personalizes the first cryptographic facility. The system also includes a second cryptographic facility which is linked to the first cryptographic facility by a public key cryptographic system.

Abstract: A system and method are disclosed for enabling the technique of deferred processing of OCR scanned mail to be compatible with existing techniques for mechanical sortation of mail that use standard sort barcode formats which are common to a given destination postal system. This enables deferred OCR processed mail to be sorted on an unsegregated basis along with other types of mail which have not been processed by the deferred OCR technique. This allows the OCR encoded mail to be processed along with other types of encoded mail during standard sort barcode that has been imprinted using prior technology such as OCR or manual code desks.

Abstract: A data processing system uses a machine-generated data structure (MGDS) to dynamically record and use the character recognition and repair histories of category fields on a document form. The MGDS includes a field data segment which has a coded data buffer portion and an error buffer portion for the extracted field image. Recognition coded data is entered into the coded data buffer portion and recognition error data is entered into the error buffer portion of the field data segment. Then subsequent repair processes can be applied to the recognition coded data by augmenting the MGDS with a repair segment for each character string which is repaired. A sequence of repair stages can be applied to a particular character string, each repair step adding another repair segment to the MGDS. At each stage of repair, the best estimate of the character string is placed into the coded data buffer portion of the field data segment.

Abstract: A method is provided by this invention wherein information needed for indexing or routing of facsimile images transmitted by standard facsimile means using CCITT protocols can be carried in the image in a form which does not interfere with conventional facsimile operation. This indexing information is carried by a pseudo bar code imbedded in the first line or lines of the image. The bar code is machine generated from operator input via a keyboard, and as such is at maximum resolution, without skew, and without scanner sampling errors. The use of multiple lines provides a bar code pattern which can be read by normal bar code reading means. This invention also includes means for extraction of the pseudo bar code from the facsimile image so that its existence is totally transparent to the users.

Abstract: An efficient method is described for predicting the performance of a data communications network operating under a window-based protocol. A state characterizing the dynamic behavior of the data communications network for consecutive operating cycles is computed. A pattern for the state is then determined having a particular repetition period. The number of data packets which are transmitted during that repetition period are then used to characterize the throughput, transit time and other performance characteristics for the data communications network.

The method includes the step of generating with a data processor, a customized polynomial expression to be associated with a selected softcopy book publisher. The method continues by merging with a data processor, the customized polynomial expression with a first shell program, forming a stamping tool program for stamping a key value onto a softcopy book published by the selected publisher. The key value results from the polynomial, using the product of an integer times a hash value of the publisher's identity, as the value of the independent variable. Then the method continues by generating with a data processor, a customized inverse polynomial expression to the customized polynomial expression, to be associated with the selected softcopy book publisher.
