Class 250: Radiant EnergyThis 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 208.1: Plural photosensitive image detecting element arrays
Subclass 566: Including coded record
Subclass 237R: Hoods, grating, baffles, diaphragms, masks
Subclass 234: Means for moving optical system
Class 358: Facsimile And Static Presentation ProcessingCommunication 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 471: Picture signal generator
Subclass 473: Hand-held reader
Subclass 474: Scanning
Subclass 483: Charge coupled device
Class 359: Optical: Systems And ElementsOptical 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 834: Plural reflecting surfaces
Class 248: SupportsDevices which carry the weight of an article or articles or otherwise hold or steady it or them against the pull of gravity, and devices for holding an article to its support, which are not otherwise provided for.
Subclass 475.1: Bracket
Subclass 468: With spring-actuated clamping of front and back
Subclass 466: MIRROR OR PICTURE TYPE
Class 382: Image AnalysisThis 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 313: Hand-held
Class 385: Optical Waveguides(1) An optical waveguiding element, which conveys light from one point to another through an optically transparent elongated structure by modal transmission, total internal reflection, or total reflectorization. (2) A combination of an optical waveguiding element with an additional broadly recited optical element which couples light or a combination. (3) A combination of an optical waveguiding element with structure which mechanically joins this waveguiding element with another or with a diverse optical element. (4) An optical modulator where the modulation of a light wave characteristic is performed exclusively within an optical waveguiding element. (5) Other miscellaneous devices formed of an optical waveguide (e.g., a waveguide sensing device) and supplemental devices which are limited to use with an optical waveguide (e.g., an external clamp or retainer).
Subclass 146: NONCYCLINDRICAL OR NONPLANAR SHAPED WAVEGUIDE
Class 235: RegistersMachines 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.
Subclass 473: Light pipes
