Abstract: A projection system includes a projection screen defining a shape and a projector configured to project an image onto the projection screen. The projector may project a static or dynamic image that has substantially the same shape as the projection screen or otherwise block portions of the projected image that are projected outside of the projection screen with the aid of a virtual mask. The virtual mask and the projection screen may be created based on a virtual shape template that defines the desired shape for the projection screen, such as with a vector outline. In some embodiments, the virtual mask and the projection screen are created based on the same virtual shape template. The virtual shape template may define a cutting path for extracting the projection screen from a suitable material.

Abstract: Systems and methods provide for assigning pieces of content to time-slots samples for measuring effects of the assigned content. Systems and methods provide for receiving pair-wise content relatedness data that identifies each piece of content as experimental content or control content relative to other pieces of content, and algorithmically assigning experimental or control content pieces to time-slot samples using the content relatedness data, wherein additional content pieces assigned to a particular time-slot sample exclude non-identical related experimental content pieces defined relative to an experimental content piece previously assigned to the particular time-slot sample.

Abstract: The multilayer film serves as a laminate. In some embodiments, the film is a multilayered structure that, in its base form, encompasses an intermediate layer with first and second outer layer affixed to opposing sides of the intermediate layer. In some embodiments, the first outer layer is a semi-crystalline fluoropolymer. In some embodiments, the intermediate layer includes a polyester and the second outer layer is an olefinic polymer.

Abstract: A display system includes a reflective display panel and a light source tailored to enhance the color gamut of the system. The panel, which may be a Cholesteric liquid crystal display panel, includes an array of reflective pixels, each pixel comprising a first, second, and third subpixel of different first, second, and third colors. The light source illuminates a front of the display panel with source light to enable observers to view images formed by the panel. The light source includes a lamp and an enhancing element. The lamp, which may be a metal halide lamp, emits lamp light that includes the first, second, and third colors. The enhancing element may be an optical filter, a supplemental LED light source or other light source, or both. The enhancing element enhances the system color gamut, for example, by increasing the color gamut area relative to illumination with the lamp alone.

Abstract: A method of making scrolls is provided that includes providing a tape having a first side and second side wherein the first side of the tape is has an adhesive disposed thereon and the second side of the tape has a release coating disposed thereon, affixing the adhesive to a solid surface, buff-coating exfoliatable particles on the release side of the tape to form a coating; and peeling the tape from the solid surface at an angle. The coating separates from the release side of the tape and curls inwards to form scrolls. The scrolls can include graphite. Also provided is a continuous method of making scrolls and an apparatus.

Abstract: A method for detecting the absence or presence of cells of interest in a liquid sample, wherein: (a) the sample: (i) comprises an extracellular medium containing an enzyme with a measurable activity; and (ii) is suspected of containing cells of interest that contain an enzyme with said measurable activity; and (b) the method comprises the steps of: (i) treating the liquid sample with a reagent that inactivates said measurable activity in the extracellular medium, but does not inactivate the measurable activity in said cells of interest; (ii) lysing the cells of interest to release the intracellular enzyme; and (iii) measuring said measurable activity. Thus the intracellular enzyme can be measured without interference from the extracellular enzyme. The invention is particularly useful for treatment of bacterially-infected blood using a detection assay based on adenylate kinase activity.
