Scanners    

Hardware, Software & Component

Overview

The patents in this portfolio relate to scanner systems. Inventions include dynamically switching OCR packages to analyze text of scanned documents, folding light paths multiple times with all the folded paths being coplanar to reduce dimension of the system enclosure, capability to scan at different resolutions, and improving signal to noise ratio of the CCD sensor.

Patent Summary

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

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 181: PATTERN RECOGNITION

Class 348: Television

Generating, processing, transmitting or transiently displaying a sequence of images, either locally or remotely, in which the local light variations composing the images may change with time.

Subclass 297: Accumulation or integration time responsive to light or signal intensity
Subclass 312: With timing pulse generator
Subclass 362: Exposure control
Subclass E5.037: By influencing the exposure time, e.g., shutter (EPO)
Subclass E5.081: Correction or equalization of amplitude response, e.g., dark current, blemishes, non-uniformity (EPO)

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 475: Facsimile illumination control
Subclass 487: Facsimile transparency image scanning
Subclass 506: Transparency image scanning
Subclass 520: Hue, saturation and luminance
Subclass 522: With histogram

Class 250: Radiant Energy

This class provides for all methods and apparatus for using, generating, controlling or detecting radiant energy, combinations including such methods or apparatus, subcombinations of same and accessories therefore not classifiable elsewhere.

Subclass 216: Optical or pre-photocell system
Subclass 225: Polarizing
Subclass 234: Means for moving optical system

Class 359: Optical: Systems And Elements

Optical elements included in this class are: Lenses; Polarizers; Diffraction gratings; Prisms; Reflectors; Filters; Projection screens; Optical Modulators; Optical Demodulators. Among the optical systems included in this class are: Compound lens systems; Light reflecting signalling systems (e.g., retroreflectors); stereoscopic systems; Binocular devices; Systems of lenticular elements; Systems involving light interference; Glare reducing systems; Light dividing and combining systems; Light control systems (e.g., light valves); building illumination with natural light; Systems for protecting or shielding elements; Optical systems whose operation depends upon polarizing, diffracting, dispersing, reflecting, or refracting light; kaleidoscopes. Further included are certain apertures, closures, and viewing devices of a specialized nature which involve no intentional reflection, refraction, or filtering of light rays. This class also includes optical elements combined with another type of structure(s) to constitute an optical element combined with a nonoptical structure or a perfection or improvement in the optical element.

Subclass 497: Using plural elements
Subclass 500: With particular material or mounting structure
