Patent Summary

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

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 31: Input/output coupler
Subclass 37: Grating
Subclass 38: End fire

Class 362: Illumination

Means and processes for casting visible radiant energy in at least one direction to render objects in that direction visible.

Subclass 231: Different wavelengths
Subclass 246: Diffusing type
Subclass 247: Reflector type modifier
Subclass 248: Shielding type modifier
Subclass 297: With or including plural, distinct reflecting surfaces

Subclass 558: Diffuser or diffusing of incident light (e.g., optical coupler)
Subclass 560: With reflective surface (e.g., mirror)

Class 313: Electric Lamp And Discharge Devices

This is the generic class for electric lamp and electric space discharge device structure. Examples of such devices are electric incandescent lamps, gas or vapor filled electric discharge tubes, including lamps, mercury arc devices, vacuum discharge tubes, radio tubes, cyclotrons, cathode-ray tubes, photosensitive discharge devices, secondary emission electron multipliers, spark plugs, and open air arc and spark devices.

Subclass 499: Semiconductor depletion layer type
Subclass 501: Light conversion
Subclass 512: With envelope or encapsulation
Subclass 113: Reflector
Subclass 114: Plural reflectors

Class 257: Active Solid-State Devices (E.G., Transistors, Solid-State Diodes)

This class provides for active solid-state electronic devices, that is, electronic devices or components that are made up primarily of solid materials, usually semiconductors, which operate by the movement of charge carriers - electrons or holes - which undergo energy level changes within the material and can modify an input voltage to achieve rectification, amplification, or switching action, and are not classified elsewhere.

Subclass E33.067: Means for light extraction or guiding (EPO)

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 850: Plural mirrors or reflecting surfaces
Subclass 853: Light concentrating (e.g., heliostat, etc.), concave, or paraboloidal structure
