Patent Summary

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

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 43: Signal formatting
Subclass 51: Stereoscopic display device
Subclass 53: Viewer attached
Subclass 56: With alternating shutters
Subclass 58: Separation by polarization
Subclass 578: Special effects
Subclass 597: For generation of soft edge (e.g., blending)
Subclass E9.055: For obtaining special effects (EPO)

Class 351: Optics: Eye Examining, Vision Testing And Correcting

Optometry - includes eye examining and vision testing instruments. These instruments must include some optical structure or they must operate in conjunction with the optical or vision path of the eye. Included also are these instruments combined with eye exercising and/or training devices; certain accessories such as test charts and/or targets which may involve projection, illuminators and supports which are peculiar to these instruments. Plus methods of operating or using these instruments. Also included are spectacles and eyeglasses, which may include the frames or mountings, with fitted opthalmic lenses, spectacles combined with holders for microphotographs, telescopes or face protecting masks, antiglare or light absorption, rear view reflectors, decorations moisture prevention or absorption, and supports or holders, temples, bridges, connectors, lens linings or rims, and nose pads or cushions, perfecting features in lenses such as with light filtering or with protecting layers. Lastly, methods of making the spectacles and eyeglasses, the opthalmic lenses, and lens repair devices.

Subclass 158: Combined
Subclass 45: Partially occluding the light-path area
Subclass 49: Polarizing

Class 349: Liquid Crystal Cells, Elements And Systems

Cells, elements, and systems which include molecules of a material having both liquid and crystalline properties. Included in this class are those which have a significant liquid crystal cell detail or liquid crystal response or properties, and in which the liquid crystal controls or changes the optical properties of electromagnetic radiation such as direction, phase, amplitude, frequency, or polarization state. This class also provides for nominal manufacturing methods for producing significant liquid crystal cell structure.

Subclass 13: Liquid crystal eyewear (glasses, goggles, etc.)
Subclass 15: Stereoscopic

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 15: Using a hologram as an optical element
Subclass 16: With aberration correction
Subclass 464: With right and left channel discriminator (e.g., polarized or colored light)
Subclass 465: Using polarized light

Class 352: Optics: Motion Pictures

Structure motion picture cameras, which record motion picture cameras, upon a single actuation a series of individual photographs which are separated in time. Generally the recording rate is related to the persistence of vision when the photograph series is used to accurately portray an action. Included in this class are exhibitors which display motion pictures and the motion picture carriers for use in the exhibitors. The exhibitors may display the motion pictures by either affording the viewer a direct view of the pictures with or without the aid of optical magnifiers, or optically projecting a real image of the pictures on a surface which is visible to the viewers. The exhibitors display the individual pictures of the motion picture series sequentially at such a rate that due to the persistence of vision of the viewer an illusion of motion is created. The individual pictures of the motion picture series may be carried on an opaque or transparent base, which may be in the form of a strip, a disc, a drum or individual plates. Motion picture cameras and/or projectors with perfecting structure are also included in this class. Plural arrangements of motion picture apparatus, and motion picture apparatus which is combined with or convertible to other devices are also provided for in this class.

Subclass 62: Sequential recording or reproducing left-right images

Class 353: Optics: Image Projectors

Projectors for particular types of objects to be projected; such as maps and aerial photographs, targets, transparent plates, information data, microscopic objects, scales and indicators, and stencils or perforated plates. Various other species and types of projectors are also included here such as kaleidoscopic, heliostats, stereoscopic and relief, pointers, gun type, moving images on screens, episcopes and cabinets including screens. Various plural and composite types of projectors are included such as projectors involving plural projected images including multicolor, projectors for images combined with real objects, projectors with manual delineation, and plural projection with a single light source. Projectors selective at the operators choice are also included as where the selection is between a slide and a film strip, between a cabinet and a distant screen, and between opaque and transparency projection.


Class 363: Electric Power Conversion Systems

Conversion systems wherein a single electrical source circuit is coupled to a single electrical load circuit.

Subclass 7: With dynamic rectifier in phase 2 to D.C. stage (e.g., commutator type)

Class 375: Pulse Or Digital Communications

This is the generic class for pulse or digital communication systems using electrical or electromagnetic signals. Such communication includes transmitting an intelligence bearing signal from one point to another in the form of discrete variations in some parameter of the electrical or electromagnetic signal.

Subclass 240.16: Motion vector
