Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 222: Dispensing

Processes and apparatus for dispensing material, and takes all such subject matter that must be classified on such basis. This class is not limited as to the character of the materials dispensed which may be in any physical state, i.e., it may be in a gas, vapor, liquid, viscous, paste-like or solid state and if in a self sustaining state may have any form or shape.

Subclass 325: Insertable cartridge or removable container
Subclass 386.5: Nonrigid follower

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.

Subclass 103: Developer seal
Subclass 116: Photoconductive member
Subclass 223: Plural diverse (e.g., color)
Subclass 262: Cartridge
Subclass 336: Radiant, infrared, or microwave
Subclass 39: Color balance
Subclass 49: Having detection of toner (e.g., patch)
Subclass 50: Control of charging
Subclass 55: Bias control
Subclass 72: Forming test image
Subclass 76: Sequential control

Class 206: Special Receptacle Or Package

(a) a container configured to hold a particular article or set of articles or material; (b) a mercantile unit - i.e., means in or by which goods (article or material) are displayed, protected, packaged or arranged in a particular manner, to facilitate sale, transportation in commerce, use or storage or (c) a packet, compact or case carried on the person of a user.


Class 430: Radiation Imagery Chemistry: Process, Composition, Or Product Thereof

This is the generic class for: (1) Forming the likeness of an object, or an instrumented or discernible phenomenon, in a chemically defined receiver or in a receiver wherein radiation produces a chemical reaction, by use of radiation. (2) Finishing an image by chemical processing regardless how formed. (3) A radiation sensitive receiver, composition, or product disclosed solely for radiation imagery chemistry, and process of making same. (4) A nonradiation sensitive-receiver, composition, or product. (5) An imaged product by a process or employing a receiver, composition, or product.

Subclass 35: Specified electric field applied or electric charging step
Subclass 46.1: Process with identified radiation-conductive element or composition (e.g., photoreceptor, etc.)
Subclass 56: Radiation-sensitive composition or product
Subclass 96: Binder for radiation-conductive composition
Subclass 109.3: Vinyl addition binder (e.g., methacrylate, styrene or vinyl chloride addition products, etc.)
Subclass 130: Thermal or energy treatment of radiation-sensitive layer, e.g., fusing, annealing, or solvent after treatment of radiation-sensitive layer, etc.
Subclass 134: Heterogeneous

Class 347: Incremental Printing Of Symbolic Information

Processes and apparatus for conveying information by selectively creating on a medium a visibly distinguishable symbol or mark composed of a plurality of portions; created portion by portion as, for example, by pixels or dots. The symbol or mark may be an alphanumeric character or an image.

Subclass 112: Electrostatic
Subclass 129: Photo scanning
Subclass 156: Fixing or fusing
Subclass 239: Specific light modulator
Subclass 240: Tone marking
Subclass 243: Including deflector
Subclass 251: Tone marking
Subclass 254: By varying dotting density
Subclass 255: Specific light modulator
Subclass 260: Having deflector
Subclass 261: Polygon

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 1.7: Flying dot (e.g., laser beam, etc.)
Subclass 1.9: Attribute control
Subclass 300: Electrostatic or electrolytic
Subclass 463: Noise elimination

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 256: Object boundary expansion or contraction
Subclass 257: Dilation or erosion (e.g., opening or closing)
Subclass 266: Edge or contour enhancement
Subclass 269: Minimize jaggedness in edges (e.g., anti-aliasing)
