This class provides, within a computer or digital data processing system with the following processes or apparatus for 1. transferring data from one or more peripherals to one or more computers or digital data processing systems for the latter to process, store, or further transfer or for transferring data from the computers or digital data processing systems to the peripherals; 2. for interconnecting or communicating between two or more components connected to an interconnection medium (e.g., a bus) within a single computer or digital data processing system; 3. for preventing access to a shared resource of a computer or digital data processing system; 4. for granting access to a shared resource of a computer of digital data processing system by one of a plurality of components of the computer or digital data processing system by interrogating each of the components in a predetermined order; 5. for determining which of a plurality of components of a computer or digital data processing system contending for access to a shared resource shall be granted access at any one time based upon a predetermined criteria; and 6. for stopping, halting, or suspending a current processing function within a computer or digital data processing system.

Subclass 72: Application-specific peripheral adapting

Class 358: Facsimile And Static Presentation Processing

Communication or reproduction of a static image or sequence of static images in which the local light, or density variations composing the image do not vary with time by a method or apparatus involving at least one of the following steps: (1) scanning a static image to capture an image-containing area by resolving it into an area; (2) communication of an image-representative signal or image-representative data over any supporting communication network; or (3) reproduction of an image-containing area in response to an image-representative signal or image-representative image data by reproducing a corresponding image area which at least one of the two dimensions is elemental, simultaneously or in a sequence. In this class, a facsimile system or method is a system or method for the communication or reproduction of an arbitrarily composed image in which the local light, or density variations composing the image do not vary with time, such as documents maps, charts, photographs, etc., but not motion picture film or video.

Subclass 1.11: Character or font
Subclass 1.18: Detail of image placement or content
Subclass 1.2: Size, resolution, or scale control
Subclass 1.9: Attribute control

Class 382: Image Analysis

This is the generic class for apparatus and corresponding methods for the automated analysis of an image or recognition of a pattern. Included herein are systems that transform an image for the purpose of (a) enhancing its visual quality prior to recognition, (b) locating and registering the image relative to a sensor or stored prototype, or reducing the amount of image data by discarding irrelevant data, and (c) measuring significant characteristics of the image.

Subclass 185: Ideographic characters (e.g., Japanese or Chinese)
Subclass 229: Context analysis or word recognition (e.g., character string)
Subclass 245: Run-length coding
Subclass 251: Quantization

Class 400: Typewriting Machines

This is the generic class for an apparatus wherein a user of the apparatus causes an intelligible character* to be imprinted on a record-medium* by a type-member* that is impressed on the record-medium, said type-member being selected from a plurality of different type-members, and the selected type-members being impressed serially to form a sequence of characters that record intelligible information.

Subclass 207: Package for ribbon facilitating mounting of ribbon on typewriter (e.g., ribbon cartridge)
Subclass 208: Package attached to typewriter
Subclass 242: Ribbon spool or mount therefor
Subclass 285.5: With reverse-direction movement of carriage
Subclass 323: Carriage-feed in two directions (e.g., continuous typing in both directions)
Subclass 630: Including aligning of sheet edge prior to typing

Class 235: Registers

Machines employed for ascertaining the number of movements of various devices or machines; also, indicating devices where the purpose is to disclose the numerical extent or quantity of movement of a machine and where the device is separate and independent of the machine whose movements are to be noted; also organized machines, such as, cash-registers, fare-registers, voting machines and calculators having registering or counting devices as essential or important elements and having in addition certain other features necessary to make up the complete machines for the purposes desired.


Class 399: Electrophotography

Electrophotographically reproducing an original by the action of light directly from the original to a photoconductive member whose electrical conductivity, electrical charge, magnetic condition, or electrical emissivity of a photoconductive medium is selectively altered by the action of light to produce an electrostatic latent image which persists after imaging based upon differences in such electrical property. The latent image is made visible by development; and the developed image may be made permanent by transfer and fixing, or fixing.
