Abstract: Light redirecting film articles include a microstructured optical film, such as a daylight redirecting film, bonded to another film. This type of assembly may serve various purposes. For example, the assembly may protect the structured film, provide additional functionality, such as diffusion or infrared reflection, and/or facilitate attachment of the microstructured optical film to a mounting surface, such as a glazing or window pane.

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: Self illuminated back and front lit shaped and two-sided signage. The signage includes a turning film having a structured surface for redirecting light and a diffuser providing for diffusion. The shape of the signage from a viewer's perspective provides the content, such as letters, to be conveyed to the viewer. Two-sided signage includes two signs arranged back-to-back, each including a turning film having a structured surface for redirecting light, a diffuser providing for diffusion, and a printed graphic. In the two-sided signage, the turning films receive light from an ambient light source and direct the light via the structured surfaces toward viewers of the two graphics in order to passively illuminate the signage. The two-sided signage can be shaped to provide content via the shape and graphics.

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 substantially planar self-folding film assembly to generate a folded three-dimensional assembly. The assembly includes a flexible support substrate, adhesive elements, and folding members. The folding members include a base, a folding region, and a hinge adjacent each folding region attached at the base to the flexible support substrate by at least one of the adhesive elements. An array of polymer actuators is co-extensive, or shaped to be not co-extensive, with each of the flexible folding members. Upon activation by a patterned light to heat conversion layer, each polymer actuator is designed and configured to provide a displacement of the corresponding flexible folding member about each hinge.

Abstract: Devices, systems, and techniques are described for providing an indication of the presence of an electrical voltage potential at one or more electrical conductors and/or electrical terminals received in an electrical coupler. Examples of electrical couplers include an illumination coupling comprising a front flange, a rear flange, and an illumination channel extending between the front flange and the rear flange and configured to encircle a portion of the electrical coupler. A plurality of illumination devices positioned at least partially within the illumination channel are configured to provide visible light emissions when illuminated that are indicative of the presence of an electrical voltage potential on at least one of the one or more electrical conductors and/or electrical terminals received within the electrical coupler.

Abstract: A system for use in wirelessly monitoring a pipeline such as a natural gas pipe. The system includes a locator configured to wirelessly transmit power and a subsoil sensor marker located adjacent the pipe and configured to wirelessly communicate with the locator. The sensor marker includes a microcontroller, a memory module, a sensor configured to sense the presence of a gas, and a power module. The power module is configured to harvest a sufficient amount of the power wirelessly transmitted from the locator in order to operate the microcontroller to take a measurement via the sensor, save the measurement in the memory module, and wirelessly transmit the measurement to the locator.
