Abstract: Hybrid signage capable of self illumination and having an active backlight. The signage includes a turning film having a structured surface for redirecting light in order to passively illuminate a printed graphic or shaped sign when the backlight is off. In the shaped sign, the shape provides the content, such as letters, to be conveyed to the viewer instead of a graphic. The signage can be actively illuminated when the backlight is on to supplemental the passive illumination.

Abstract: Optical devices include a light source and an optical article, where the optical article is an acid-free, non-yellowing pressure sensitive adhesive light guide. The light source is optically coupled to the light guide such that light emitted by the light source enters the light guide and is transported within the light guide by total internal reflection. The light guide includes a plurality of features oriented to extract light being transported within the light guide.

Abstract: An air filter includes filter media, a sensor, and circuitry coupled to the sensor, the circuitry configured to receive data from the sensor representative of the condition of the filter media and wirelessly transmit such data. The data may be received by a device with a display to use the information to present an indication of the filter media condition to a user.

Abstract: Disclosed herein is an optical device having a light source and a viscoelastic lightguide. Light from the light source enters the viscoelastic lightguide and is transported within the lightguide by total internal reflection. The viscoelastic lightguide may comprise a pressure sensitive adhesive. The optical device may be used in a variety of constructions wherein the device emits light being transported within the viscoelastic lightguide. Constructions include those used for signs, markings, illumination devices, display devices, keypad assemblies and tail light assemblies for vehicles.

Abstract: Marketing strips having a light source and a flexible viscoelastic lightguide for displaying products or product related information, or illuminating a graphic on the marketing strip and products adjacent it. Light from the light source enters the viscoelastic lightguide and is transported within the lightguide by total internal reflection until the light exits from surfaces of the lightguide and through the graphic. The viscoelastic lightguide can include a pressure-sensitive adhesive, which adheres the lightguide to the marketing strip and enhances structural support for it. The light from the lightguide can illuminate products and labels on the marketing strip. The lightguide can also include a bevelled edge with light exiting the edge downward and backward from the marketing strip to illuminate products it.
