  • Patent number: 7052746
    Abstract: A privacy screen for a display (e.g., a LCD) includes having a polarizing film and a birefringent film is described. The privacy screen transmits substantial amounts of light emanating from the display in an orthogonal (or near-orthogonal) direction while not transmitting substantial amounts of horizontal, non-orthogonal light emanating from the display. In this manner, a privacy effect results in that the display is viewable by someone only when that someone is essentially directly in front of the display.

  • Patent number: 7048991
    Abstract: An elastic composite is formed by securing an elastic member to a substrate along a securement path extending longitudinally of the substrate. The position of the elastic member on the substrate varies laterally along the longitudinally extending securement path in a generally periodic wave pattern having at least one period within the securement path. The periodic wave pattern is such that the elastic composite is more stretchable in the direction of the securement path than transverse to the securement path. In another embodiment, the securement path varies laterally as it extends longitudinally along the securement path. The position of the elastic member varies transversely within the securement path to at least partially define a width of the securement path.

  • Patent number: 7011879
    Abstract: A polymeric twist tie 20 is taught that utilizes a thermoplastic monofilament 22 having an oriented characteristic produced by stretching a pre-heated monofilament through a heated, volume reducing die. The monofilament 22 is then coated 30 circumferentially with an extrusion of thermoplastic enclosing the monofilament while simultaneously forming a pair of opposed wings 32 integral with the coating. The wings extend outwardly from the coated monofilament allowing the tie to be twisted upon itself with the monofilament retaining its basic configuration and the wings stretching and bending to conform within a coupled twist. The oriented monofilament is fabricated using high density polyethylene and the covering extruded with low density polyethylene which are dissimilar in density, melt index and basic thermoplastic morphology.

  • Patent number: 6989197
    Abstract: A polymer composite structure having resin matrix interlayers reinforced with shape memory alloy (SMA) particles. In one preferred form Nitinol® alloy particles are used for the SMA particles. The Nitinol® alloy particles may comprise cylindrical, oval or spherical shaped particles and are intermixed in the resin of the resin matrix interlayer(s) of the composite structure. The SMA particles provide superelastic, reversible strain properties that significantly improve the damage resistance, damage tolerance (e.g. compression-after-impact (CAI) strength) and elevated temperature performance of the composite structure without negatively affecting the hot-wet compression strength of the composite structure. The polymer composite structure is ideally suited for aerospace and aircraft applications where lightweight and structurally strong materials are essential.
