  • Patent number: 6023528
    Abstract: A sequence of documents is delivered to an optical scanner in which each document is scanned to form a digital image representation of the content of the document. The image representation is automatically examined by data processing apparatus to select search words which meet predetermined criteria and by which the document can be subsequently located. The search words are stored in a non-volatile memory and the entire document content is stored in mass storage in image form. A font table is established and images of entered search words are constructed from the table. Unrecognized or imperfectly formed ambiguous characters are stored with the font table and are used in the construction of search words to eliminate text editing or are stored with converted characters of search words. The approach can also be used to eliminate editing of full text-converted data bases during input.

  • Patent number: 5444840
    Abstract: A sequence of documents is delivered to an optical scanner in which each document is scanned to form a digital image representation of the content of the document. In one embodiment, the image representation is converted into code (ASCII) and is automatically examined by data processing apparatus to select search words which meet predetermined criteria and by which the document can be subsequently located. In another embodiment, the image is not converted. The search words are stored in a non-volatile memory in code form and the entire document content is stored in mass storage, either in code or image form. Techniques for selecting the search words are disclosed, including establishing a font table and constructing images of entered search words from the table.

  • Patent number: 5396588
    Abstract: A method of manipulating information is disclosed in which the data is stored as a digitized image and is retained in image form for various data processing manipulations. A font table is formed having a matrix of fonts correlated with characters and symbols in code form such as ASCII. Desired material in the stored documents is located using pattern-match searching with a parallel processor search engine.

  • Patent number: 5133024
    Abstract: A system for using market-available scanner and character recognition hardware and software in preparing information from documents for mass storage. Results of character recognition are selectively defined in image and extracted from storage. A camera can also be used for digitizing large and small documents as well as microfilm and microfiche. A multitasking controller with its own microprocessor and RAM provides real time processing. The contents of documents can be stored in image, totally or selectively, conversion from digitized image can be made totally and selectively and passwords from documents can be identified and stored in code. Keyed information can be added as each document's contents are prepared.

  • Patent number: 4726065
    Abstract: An improved method of entering instructions to a data processing system to modify the display includes voice recognition. In one embodiment the screen is divided into sectors and the memory supplying data bits to the display is functionally divided in a corresponding way. The operator utters sector identification and change instructions. Voice recognition apparatus provides recognized location information and instructions to an assembler from which commands are issued to the system. In another embodiment a touch responsive screen is used in conjunction with spoken instructions. The system is particularly useful in preparing material for microform storage.

  • Patent number: 4553261
    Abstract: A system for accepting documents and handling the data contained therein includes a reader and digitizer for producing and storing fragmented or digitized images simulating the characters and graphics on the document. Each document is marked with a unique identifying code. Selected portions of the data are converted to a machine code and stored and portions of the digitized material are also stored. Converted and unconverted segments can be recalled for complementing and verifying the machine code. Access is available to either in storage.

  • Patent number: 4273440
    Abstract: A method of recording images of selected areas of source documents by photographic, video or similar camera analog recording techniques. Embodiments of apparatus to perform the method include devices for feeding the source record, aiming the camera and arranging the recorded segments in an order independent of the original order of the data segments on the source record. Also disclosed are systems usable in conjunction with the above for encoding the data in digital form and storage thereof.
