Abstract: Disclosed herein is an optical device including a light source and an optical article. The optical article includes a lightguide and a viscoelastic layer disposed on the lightguide. Light emitted by the light source enters the lightguide and is transported within the lightguide by total internal reflection. The viscoelastic layer manages light, for example, at least about 50%, or less than about 10%, of light that enters the lightguide may be extracted. The optical device can be used in a variety of constructions for signs, markings, display devices, keypad assemblies, tail light assemblies and illumination devices.

Abstract: A light collimating horn assembly having two horns, one contained within the other. The horns have reflective surfaces facing each other. A light source, such as a ring of light emitting diodes, is located between the reflective surfaces of the horns.

Abstract: A system for containing a stack of face masks and dispensing individual face masks from the stack. The system includes a container and a stack of folded face masks. The container has a bottom panel forming a cut-line that defining a flap that is transitionable to an open state to generate an opening in the bottom panel. The stack is disposed within the container, and each face mask includes an elastic sheet forming a central portion and opposing first and second lateral end portions. Each face mask is folded such that a section of the first lateral end portion extends from a first fold line along the central portion. In a dispensing mode, the first lateral end portion of a bottommost folded face mask naturally drops through the opening due to gravity.
