    摘要： An emergency supplementary vision device comprises a collapsible tube made of airtight material and having an expanded form and a compact stowed form; first and second clear members disposed at respective first and second ends of the tube to enable the user to see through said tube and observe a source of information at the other end while smoke or other particulate matter is in the environment; and a filter operably associated with the tube to filter the ambient atmosphere and fill the interior of said tube with clear air when said tube is expanded to its expanded form.

    摘要： A system for controlling the transmittance of electromagnetic energy through an aircraft cockpit canopy, and more particularly a canopy panel structure incorporating selectively energizable liquid crystals therein for controlling the transmittance of the electromagnetic energy and/or for integrating an information display in the canopy panel structure. Also disclosed is a method for controlling the transmittance of electromagnetic energy through an aircraft cockpit canopy utilizing a liquid crystal arrangement which is incorporated into the canopy panel structure.

    摘要： An optical transparency adapted to substantially attenuate electromagnetic pulses incident on it, yet transmit visible light with minimal distraction being caused by Fraunhofer diffraction. The transparency includes a transparent sheet and a laminated, electrically-conductive grid that defines a densely-packed array of apertures. Each aperture is a modified polygon having multiple curved sides, such that visible light from a remote point source of light is diffracted by the curved sides of each aperture over multiple, diverging, fan-like areas and minimal distraction to a person viewing through the transparency is thereby provided.

    摘要： A cockpit enclosure or canopy assembly for aircraft including a canopy comprising fore and aft portions and a platelike protective shield constituting armor glass. The forward portion and protective shield constituting primary and emergency windshields, respectively, of the canopy assembly. The protective shield also functioning as a combining glass for head-up display or like equipment. The shield and canopy assembly cooperating to insure maximum visibility, improved aerodynamic features, reduces clutter and improves neatness etc., of the canopy area.
