Patent Summary

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

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 345: Computer Graphics Processing And Selective Visual Display Systems

Processes and apparatus for selective electrical control of two or more light-generating or light-controlling display elements* in accordance with a received or stored image data signal. The image data includes character, graphical information or display attribute data. The image data may include, for example, information data from a peripheral input device, from the reception of a television signal, from the recognition of image data, or from the generation or creation of image data by a computer.

Subclass 89: Gray scale capability (e.g., halftone)

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.

Class 340: Communications: Electrical

Communications - the handling of information or intelligence, restricted to the conveying of said information or intelligence between geographically spaced points. Information or intelligence is defined as being, matter which is handled by signaling systems or signaling devices (such as telegraph systems) or by that portion of nonsignaling systems or nonsignaling devices (such as power supply systems) which is designated in the arts as having a control function (such as the supervisory circuits which control the circuit breakers of an electric power network). Handling, as used above, is defined as being the active coaction between the tangible communication system or device and the intangible information or intelligence, and such coaction may assume various forms, such as transmission, storage, exhibiting, etc.
