Patent Summary

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

Class 372: Coherent Light Generators

An assembly of electrical, mechanical, and optical components produces an intense, coherent, directional beam of light by stimulating electronic, ionic, or molecular transitions to lower energy levels.

Subclass 21: Nonlinear device
Subclass 22: Frequency multiplying (e.g., harmonic generator)
Subclass 45.013: With saturable absorption layer
Subclass 99: Reflector
Subclass 102: Grating

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 37: Grating

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.

Subclass 30: COMPOSITE PROJECTED IMAGE
Subclass 31: Multicolor picture
Subclass 34: Plural projection paths with single light source
Subclass 38: UNITARY PLURAL REFRACTING SURFACES
Subclass 94: PLURAL
Subclass 98: REFLECTOR

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 326: OPTICAL FREQUENCY CONVERTER
Subclass 328: Harmonic generator
Subclass 558: DIFFRACTION
Subclass 566: From grating
