    Abstract: A patterned article includes a polymeric layer having opposing first and second major surfaces and defining a plurality of through openings therein. For each through opening in at least a sub-plurality of the through openings, a metallic body is disposed in the through opening. The metallic body has a first outermost surface, an opposite second outermost surface and at least one lateral sidewall extending therebetween. The first outermost surface of the metallic body is substantially flush with the first major surface of the polymeric layer. Each lateral sidewall extends from the first outermost surface of the metallic body toward or to, but not past, the second major surface of the polymeric layer. The metallic body is substantially coextensive with the through opening in at least one cross-section parallel to the polymeric layer. The metallic bodies can be electrically isolated from one another.

    Abstract: A light guide for lighting keys of a keypad in handheld devices. The light guide includes a film and a light emitting diode optically coupled to it. The film provides for substantial total internal reflection of light. A surface of the film opposite the keys includes a plurality of discrete areas, and each of the areas has one or more microstructured features such that each of them extract from the film a substantial amount of light incident upon them by reflecting and redirecting the light such that it impinges upon the film beyond the critical angle for total internal reflection. The microstructured features in each of the areas are adjusted such that they obtain substantially uniform extraction of light from the light source. The light guide can provide sufficient illumination of the keys using only a single light emitting diode as the light source.

    Abstract: A light guide includes an extractor layer and a substrate layer. Each layer has a first major surface and a second major surface. The second major surface of the extractor layer is in contact with the first major surface of the substrate layer, and the first major surface of the extractor layer has a plurality of discrete light extractors capable of extracting light propagating in the light guide such that light is extracted in a predetermined pattern over the first major surface of the extractor layer. In some embodiments, at least one of the extractor layer or substrate layer is flexible.

    Abstract: A magnetic film assembly includes a coil having a plurality of turns defining a first major boundary surface of the coil, such that when energized, the coil generates an in-plane magnetic field component in a region of interest in air proximate and substantially parallel to the first major boundary surface, the in-plane magnetic field component having a magnetic field strength H that varies between a maximum Hmax and about 10% of Hmax in the region of interest in air; and a magnetic layer disposed on the coil so as to include the region of interest, such that when energized, the coil generates a magnetic field inducing an in-plane magnetic flux density B in the magnetic layer in the region of interest that varies less than about 5% in the region of interest.

    Abstract: An optical film including a collimating reflective polarizer and a structured layer disposed on a major surface of the collimating reflective polarizer. The structured layer includes a plurality of three-dimensional structures on an outer major surface of the structured layer facing away from the collimating reflective polarizer. The three-dimensional structures have a surface normal having an angle relative to a plane of the optical film that is in a range of about 35 degrees to about 55 degrees over at least 50 percent of a surface area of the three-dimensional structures.
