Abstract: Lightguides including pixelated images, and methods of making the lightguides are provided. The lightguides include an image formed on a major side which is illuminated for directly viewing. The image includes an elongated portion being pixelated into an array of pixels. Each of the pixels includes a single light extracting structure adapted to receive the propagating light within the lightguide along the optical axis and extract the received light transversely out of the lightguide.

Abstract: A taillight article (100) including an optically clear light guide (110) having an light emission front surface (112) and an opposing rear surface (114) and a side surface (118) separating the front surface (112) and the rear surface (114) is described. A first light source (120) is configured to direct light into the side surface (118) and indicate a first signal-function. A plurality of light extraction features (116) are on or within the optically clear light guide (110) and are configured to direct light from the first light source (120) out through the emission surface (112). A light reflection element (130) is spaced apart from the rear surface (114) and defines a cavity (135) that is observable by a viewer.

Abstract: Keyed fluid-handling devices comprise a fluid-handling device such as a filter, a bypass, or an adapter and an optical key. The optical keys are amenable to all types of filter component and can be readily retrofitted to existing designs. The optical keys may be formed from a variety of materials and combination of phases. That is, optical keys may comprise one or more solid materials, or perhaps may result from a combination of: solid materials, such as in transparent or semi-transparent polymers or glass; liquid fluids, such as water; and gaseous gaps such as an air gap. Optical keys may be light conduits or light guides. Filter manifolds comprise optical locks to ensure compatibility of the filter components.
