Patent Summary

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

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 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 464: With right and left channel discriminator (e.g., polarized or colored light)
Subclass 466: Stereo-viewers

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 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 E13.005: Having a single 2D image pickup sensor (EPO)
Subclass E13.006: Using spectral multiplexing, i.e., simultaneously capturing several geometrical viewpoints separated by different spectral characteristics (EPO)
Subclass E13.014: Having two 2D image pickup sensors representing the interocular distance (EPO)
Subclass E13.019: Color aspects (EPO)
Subclass E13.02: With monoscopic to stereoscopic image conversion (EPO)
Subclass E13.022: From a 3D object model, e.g., computer generated stereoscopic image signals (EPO)
Subclass E13.025: Synchronization or controlling aspects (EPO)
Subclass E13.029: Using a lenticular screen (EPO)
Subclass E13.03: Using a parallax barrier, e.g., spatial light modulator (EPO)
Subclass E13.033: Color aspects (EPO)
Subclass E13.037: With spectral multiplexing, i.e., simultaneously displaying left and right images separated using glasses with different spectral characteristics, e.g., anaglyph method or Pullfrich method (EPO)
Subclass E13.038: With polarization multiplexing, i.e., simultaneously displaying left and right images separated using glasses with different polarizing characteristics (EPO)
Subclass E13.04: With temporal multiplexing, i.e., alternatively displaying left and right images separated in time and using glasses to alternatively block the right and left eye (EPO)
Subclass E13.058: Using an image projection screen (EPO)
Subclass E13.059: Synchronization or controlling aspects (EPO)
Subclass E13.062: Coding or decoding stereoscopic image signals (EPO)
Subclass E13.064: Processing stereoscopic image signals (EPO)
Subclass E13.071: Transmission of stereoscopic image signals (EPO)
Subclass E13.072: Multiplexing or demultiplexing different image signal components in stereoscopic image signals (EPO)

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 61: With image separation by special projection screen
