  • Patent number: 5018007
    Abstract: A relatively thin projection screen includes a sheet of parallel, specially treated fiber optic cables that emit light transversely, and an overlying liquid crystal display screen formed of a plurality of adjacent and individually modulatable liquid crystal shutters. A dot matrix of pixels is generated by controlling the sequential transmission of light to the optical fibers, and the transparency or opacity of the overlying shutters. As each row of the optical fibers is sequentially energized by a light source, the columns of liquid crystal shutters are simultaneously opened or closed in accordance with signals derived from a television video signal. This provides an optical reproduction of the television signal from the pixels of light defined at the cross over points of the rows and columns. The liquid crystal shutters are modulated to allow a varying amount of light to pass through so that different levels of brightness may be obtained.

  • Patent number: 4979026
    Abstract: A viewing system is provided for presenting a real image in space that is rotated extremely rapidly so that an entire audience, regardless of an individual's position about the viewing system, can view the same image substantially simultaneously and continuously. An electronic image rotation system distorts, processes and rotates an image upon a cathode ray tube (CRT), and a parabolic mirror arrangement projects the image from the CRT to provide a rotating real image in space. A rotatable polarized screen and a separate, stationary polarized screen cooperate to define a viewing window which remains continually aligned with the rotating real image in space.

  • Patent number: 4943851
    Abstract: A viewing system is provided for presenting a projected image upon a rear projection screen that is rotated extremely rapidly about a vertical axis which exactly bisects the picture in the vertical plane. The rotational rate is such that an entire audience, regardless of their position about the viewing system, can view the projected image simultaneously. The 360.degree. viewing system features an optical system which rotates with respect to a cathode ray tube about the vertical axis in synchronization with the rotation of the projection screen. A liquid crystal display (LCD) screen is utilized to define a viewing window which is continuously redefined at sequential intervals to remain continually aligned with the projection screen.

  • Patent number: 4901140
    Abstract: A viewing system is provided for presenting a real image in space that is rotated extremely rapidly so that an entire audience, regardless of an individual's position about the viewing system, can view the same image substantially simultaneously and continuously. An electronic image rotation system distorts, processes and rotates a black and white image upon a cathode ray tube (CRT), and a parabolic mirror arrangement projects the image from the CRT to provide a rotating real image in space. A liquid crystal display (LCD) screen is utilized to define a filtered viewing window which is continuously redefined at sequential intervals to remain continually aligned with the rotating real image in space. The LCD screen includes normally opaque red, green and blue filter panels which operate to give color to the real image in space.

  • Patent number: 4679574
    Abstract: A cigarette made of cut tobacco rolled in a paper having a refractory layer with a predetermined pattern bonded to or imprinted upon the interior surface of the paper. The pattern is formed outside of rows and columns of what eventually become elongated slots when the paper burns away. The slots are arranged in lengthwise rows and also are arranged in columns. Each row has a slot midpoint which lies midway between slots in each adjacent row.

  • Patent number: 4578709
    Abstract: A flat TV screen is provided by overlapping rows and columns of fiber optics. Each cross-over point will emit more light than radiates from the side of a single optical fiber when both of the crossing fibers are energized. Therefore, a dot matrix can be generated by controlling the entrance of light into the ends of the optical fibers in the rows and columns. The rows of optical fibers are sequentially energized by a light signal of constant brightness. The columns in turn are successively energized during the time period that each row is energized with signals derived from a TV video signal to thereby provide an optical reproduction of the TV signal from the dot matrix of light defined at the cross over points of the rows and columns.
