    Abstract: Disclosed herein is an optical article having a top layer with a structured surface that collimates light, a core layer secured to the top layer opposite the structured surface, and a bottom layer secured to the core layer opposite the top layer. Either the top layer or the core layer includes a first extrudable polymer having a flexural modulus of greater than 2.5 GPa, and the other layer includes a second extrudable polymer having a flexural modulus of 2.5 GPa or less, an impact strength of greater than about 40 J/m, and tensile elongation at break of greater than about 5%. The bottom layer includes a third extrudable polymer. The bottom layer of the optical article may be structured to diffuse light. One or two optical articles may be secured to an optical film such as a polarizer film. Methods and display devices are also disclosed herein.

    Abstract: In general, techniques are described for the creation and execution of accurate models for the manufacture of complex, multi-layered materials. The techniques may be used to calculate variations of a process parameter within the material during the manufacturing process. A method comprises receiving segment data that partitions a manufacturing process into a set of segments having at least one layer of a material. For example, the segment data may partition the manufacturing processes along a path traversed by the material within the manufacturing process. The method further comprises receiving curvature data for the layers, and calculating values for a process parameter through the layers of the segments as a function of the curvature data. The method may comprise invoking a one-dimensional model, such as a one-dimensional finite difference model, to calculate the values for the defined segments and layers.

    Abstract: An apparatus for capping a stem web including a cooled roll, a first heated nip roll positioned to form a first nip with the cooled roll, and a second heated nip roll positioned to form a second nip with the cooled roll. The cooled roll has a diameter that is at least 30% larger than a diameter of the first or second heated nip roll. In an embodiment, the two nips are on opposite sides of a larger central cooled roll positioned between the heated rolls. In an embodiment, the reaction forces between the rolls are measured and controlled at each end of each of the heated rolls. The invention is particularly adapted to making abrasive particles that are attached to a driving mechanism via headed stem fasteners formed by the method.

    Abstract: A high performance tape reel with an outwardly facing cylindrical tape winding surface parallel to a drive pin bore on a reel hub. The hub has a pair of hub reference surfaces adjacent to the winding surface for aligning tape flanges. Flanges are attached to the hub at a location remote from the winding surface and magnetic tape. A drive cap with a reel pin bearing surface is attached to the hub so that the reel pin bearing surface substantially covers one entrance to the drive pin bore.
