Abstract: An optical system includes an extended illumination source configured to emit light from an extended emission surface thereof and a light redirecting layer disposed on the extended emission surface. The light redirecting layer has a structured major surface that includes a regular array of light redirecting structures, each light redirecting structure including a plurality of facets; and a plurality of discrete spaced apart window segments. The optical system includes a plurality of reflective segments where each reflective segment is disposed on a corresponding window segment. For substantially normally incident light, each reflective segment has a total: average optical reflectance of at least 30% in a visible wavelength range extending from about 420 nm to about 650 nm; and optical transmittance of at least 10% for at least one infrared wavelength in an infrared wavelength range extending from about 800 nm to about 1200 nm.

Abstract: A retroreflective article including a binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements include a first layer that is disposed between the transparent microsphere and the binder layer and a second layer that is disposed between the transparent microsphere and the binder layer. At least one of the first layer and the second layer is a reflective layer; and, the first reflective layer and the second reflective layer differ in reflectivity. For at least some of the retroreflective elements, at least a portion of the second reflective layer is positioned in-parallel to the first reflective layer.

Abstract: At least some embodiments of the present disclosure an electrostatic sheet jamming device comprising a first sheet having a first conductive layer, a first dielectric layer disposed adjacent to the first conductive layer, and a second sheet comprising a second conductive layer and disposed proximate to the first dielectric layer. The first dielectric layer is disposed between the first conductive layer and the second conductive layer. The first sheet and the second sheet are non-extensible and flexible, wherein the first sheet and the second sheet are slidable relative to each other in a first state. The first sheet and the second sheet are jammed with each other in a second state when a voltage is applied between the first conductive layer and the second conductive layer. In some embodiments, the applied voltage is less than or equal to a break-down voltage of air at a distance between the first conductive layer and the second conductive layer.

Abstract: A nanostructured article having a first layer with a nanostructured surface is described. The nanostructured surface includes a plurality of pillars extending from a base surface of the first layer. The pillars have an average height greater than an average lateral dimension of the pillars. An average center-to-center spacing between pillars is no more than 2000 nm. The average lateral dimension is no less than 50 nm. Each pillar in the plurality of pillars has at least a lower portion and an upper portion where the lower portion is between the upper portion and the base surface, and the upper and lower portions have differing compositions. The nanostructured article includes a second layer disposed over the plurality of pillars and extending continuously to the base surface.
