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 translation: 混合标志能够自我照明并具有主动背光。 标牌包括具有用于重定向光的结构化表面的转向膜，以便当背光关闭时被动地照亮印刷图形或成形标志。 在形状符号中，形状提供了要传达给观看者而不是图形的内容，例如字母。 当背光打开时，标志可以被主动照亮以补充被动照明。

Abstract: A backlight is disclosed and includes a visible light transmissive body primarily propagating light by TIR with a light input surface and a light output surface and a light guide portion and a light input portion. The light guide portion has a light reflection surface and a light emission surface. The light input portion has opposing side surfaces that are not parallel. One of the opposing surfaces is co-planar with either the light emission surface or the light reflection surface. A light source is disposed adjacent to the light input surface. The light source emits light into the light input portion. A reflective layer is disposed adjacent to or on the opposing side surfaces.

Abstract: Light transmissive non-slip treads coupled to a light directing film having a structured surface for redirecting light oriented on a first axis. The non-slip treads may appear to be specifically illuminated, as if by dedicated light fixtures, but may instead be illuminated by ordinary ambient light.

Abstract: A sensor comprising a thin film photovoltaic pixel is fitted with optics to provide a field-of-view for the sensing of persons, or other objects, entering or exiting said field-of-view. When a person enters the field-of-view, a processor may sense such entry, then provide signals to other electronic apparatus indicative of such an event.

Abstract: An illumination device, such as a backlight for electronic display devices, is disclosed. The illumination device includes a viscoelastic lightguide optically coupled to a light source, and a nanovoided polymeric layer is used in conjunction with the lightguide to manage light emitted by the light source. The viscoelastic lightguide may be a pressure sensitive adhesive.

Abstract: A system may include one or both of a light emitter and a light receiver. The system may include an optical filter adjacent one or both of the light emitter or the light receiver. The optical filter includes a wavelength selective scattering layer. The wavelength selective scattering layer may have a near-infrared scattering ratio of less than about 0.9. The filter may have a visible reflective haze ratio of greater than about 0.5. A method may include disposing the wavelength selective scattering layer adjacent one or both of the light emitter and the light receiver. An article may include the optical filter. The wavelength selective scattering layer may have an average near-infrared scattering of less than 60%, an average visible scattering of greater than 10%, and a difference between the % total visible reflectance and the % diffuse visible reflectance of less than 20.
