  • Publication number: 20050167598
    Abstract: Method and apparatus for testing ultralow moisture permeation through a sample such as a thin barrier film by exposing one surface of a sample to be tested for moisture permeation to a predetermined humidity of HTO. The HTO permeating therethrough is collected in a stream of dry gas, preferably methane, at a known very slow flow rate, and monitored for its radioactivity content. By very carefully sizing the respective chambers, continuously monitoring using a particularly sensitive device and appropriately converting the signals, accurate assessment of permeation rates even as low as very small fractions of a gram of water per square meter per day can be obtained. Ultralow oxygen permeation is alternatively measured using 14CO. Methods are also shown for measuring permeation that would occur through a perimeter seal and for measuring permeation which would result from gaseous entry into edge surfaces of a composite film.

  • Publication number: 20050084659
    Abstract: A head-up display (HUD) is incorporated within a windshield of a motor vehicle at a location through which the operator's field of vision onto the highway ahead must pass. The TOLED is formed of transparent materials and laminated, along with a polymeric interlayer, between two plies of glass; a pair of elongated conductors electrically connect the electrodes of the TOLED to an edge of the windshield. Upon the receipt of signals from a controller, light is created within the plies of the windshield to immediately convey a HUD to the operator without the need for his or her vision to leave the highway ahead.
