  • Publication number: 20050008843
    Abstract: This invention discloses a composite sheet with confined flexibility, a method of making it and a safety tire in which said composite sheet of present invention is used. Said composite sheet comprises a mechanism embedding in rubber. Said mechanism allows the composite sheet bend easily within predetermined ranges and confines the composite sheet from further bending when the limits of said predetermined ranges are reached. Said safety tire comprises a pair of said composite sheets disposing at sidewall regions and a layer of said composite sheet disposing above belt package. Said safety tire has high puncture-resistance and comparable riding comfortness over conventional tire. Said safety tire is self-supporting and still provides good maneuverability to vehicle under zero inflation pressure.

  • Patent number: 6132048
    Abstract: A single display assembly (10) has an electronically controllable display (11) with a plurality of display elements (12) and sandwiched by two support plates (13,14), two polarizers (15,16) and two selective reflectors, namely a first selective reflector (17) and a second selective reflector (18). Support plates (13,14) and polarizers (15,16) are transparent media to permit passage of light. Selective reflectors (17,18) are holographic reflectors that are each pre-recorded with characteristics that includes a range (19 or 20) of predetermined incident angles relative to inward facing horizontal surfaces (24,25) and an angular transparency range (not shown) for passage of light. Assembly (10) has two opposite sides (21,22) to view indicia provided by display elements (12). Indicia can be selectively viewed from either of sides (21 or 22) without interference from external background of a remaining one of sides (21 or 22).
