Abstract: A curved display includes a display panel having a curved major surface and a light control film disposed proximate the display panel. The curved major surface is curved about a first axis, and a central portion of the curved major surface has a surface normal along a second axis substantially orthogonal to the first axis. The light control film includes a major surface having a substantially same shape as the curved major surface and includes a plurality of alternating optically transmissive and optically absorptive regions. In a cross-section orthogonal to the first axis, a transmissive region and adjacent absorptive regions define a central ray transmission direction through the optically transmissive region such that a light ray emitted by the display panel and transmitted through the optically transmissive region along the transmission direction is refracted upon exiting the curved display into a direction substantially parallel to the second axis.

Abstract: Provided are an apparatus and methods for dispensing a composition, the apparatus includes a barrel (120) having an inlet (128) and an outlet (129), a screw (122) received in the barrel, and a drive mechanism operatively coupled to a shank end (134) of the screw to rotate the screw. The screw is hollow and includes both interior and exterior surfaces, the interior surfaces defining a cavity (142) adjacent to the outlet, and wherein the screw further includes a plurality of apertures (140) through which the cavity and exterior surfaces communicate with each other. The apertures are located along a perforated portion (146) of the cavity, where the perforated portion can have a transverse dimension that increases with distance from the shank end. The apertures can also provide a hole area, relative to the exterior surface of the screw, that increases with distance from the shank end. The screw can also include a helical flight (132) having a raised flight section (150) and one or more lowered flight sections (152), where the apertures are at least partially located on the lowered flight section.

Abstract: A unit for use in evaporative cooling includes a first capped frame and a second open frame opposite the first frame. Posts are located between and coupled to the first and second frames. A porous hollow fiber membrane extends around the posts between and coupled to the first and second frames to form an interior volume. The first and second frames are configured for flow of water between them via the membrane. The membrane is configured to transport the water between the first and second frames and to provide for air flow from the interior volume through the membrane for evaporative cooling. The cooling unit can have a rounded square or diamond-shaped cross-sectional shape.
