  • Patent number: 5235654
    Abstract: An advanced data capture architecture is disclosed which enables the free-definition and re-definition of the format of document forms without requiring any reprogramming of the data processors which capture and use the data on the completed forms. The architecture encompasses the interactive operation of a host processor and one or more workstations in a data processing system. It includes the interaction between a host processor and a workstation in providing a list of common operand names which are meaningful to an application program running on the host. It includes the operation of the workstation creating a new document form using the list of common operand names. It includes the workstation performing character recognition of the filled-out form, transforming its information into coded data. It includes the workstation assembling a field data segment for each field, containing the common operand, the coded data and the popular name for the field.

  • Patent number: 5153936
    Abstract: A data processing system stores and displays digital images, and includes a workstation having a document input scanner for digitizing document images at a first resolution, an image display unit for displaying digitized document images at a second resolution which is less than the first resolution and a printer for printing digitized document images at a third resolution greater than the second resolution. The system reduces communications traffic and assures fast access time on the network since the bulk of the traffic will utilize the smaller compressed data records required for the second resolution. However, these improvements in communication traffic and access time do not sacrifice the availability of high resolution compressed data records occasionally needed for printing and other high resolution operations.

  • Patent number: 5093911
    Abstract: A system is described in which a user enters a search term at a user location, that search term being associated with a plurality of image objects which are stored at a plurality of geographically diverse locations within the system. The search term is then transmitted to a central index location where there is stored a central index which includes the object name and location and associated data for each of the distributed objects associated with the search term. Optionally, the associated data may be transmitted from the central location back to the user location for display to the user, who can then select which of the several objects or perhaps all of the objects to be accessed from the diverse geographic storage locations. The user can enter his selection at the user location and that selection will be transmitted back to the central index location.

  • Patent number: 5058185
    Abstract: A method and apparatus which allows an object management and delivery system to perform capture, prefetch, display, print and/or modify operations with only a modicum of interaction between the operations of a host computer system and the object management and delivery system. Host computer/object-management system interaction is typically limited to: operation requests transferred from the host computer to the object management system; record registration data transferred from the object management system to notify the host computer that an object record has been stored; and/or error data transferred from the object management system to notify the host computer when the object management system encounters an error in trying to perform an operation requested by the host computer.

  • Patent number: 5025396
    Abstract: The method merges an alphanumeric data stream with a digitized image file. It comprises the steps of inputting a digitized image file in a first input terminal and storing the digitized image file on a first storage medium. The method then inputs an alphanumeric character string in a second input mechanism and stores the alphanumeric character string in a second storage medium. The method then converts the alphanumeric character string stored in the second storage medium into a bit pel image of the alphanumeric character string by substituting a two dimensional bit pattern of pels for each respective character in the string. The method then performs a logical combination of the bit pattern for each respective alphanumeric character with the digitized image at respective intended character locations in the digitized image area and outputs the logically combined digitized image with the alphanumeric character string superimposed thereon.
