Abstract: System and technique for inspecting a moving film by measuring the levels of light transmission through a thickness dimension of the film are described. The system includes a light source configured to provide light including a particular wavelength, or a particular range of wavelengths. The light from the light source is directed toward a first surface of the film, and an image capturing device is located adjacent to the light source on a second side of the film opposite the first surface, the image capturing device configured to measure the levels of light intensity exiting a second surface of the film. Measurements of the level of the light intensity passing through the film may be spatially synchronized to physical positions along the film to generated at least one roll map indicative of light transmission characteristics of the film over the imaged portions of the film.

Abstract: Optical films having an optical axis with an orientation that varies along a width of the optical film and having one or more indicia recording the orientation of the optical axis at a plurality of locations in the optical film are provided. Systems and methods for producing and for converting the optical films are provided.

Abstract: A reflector laminate comprises a reflector having a first major surface and a second major surface opposite the first major surface, and a visible light non-transmissive adhesive tape having a major adhesive surface and a second major surface. The adhesive surface is in contact with the first major surface of the reflector and at least a portion of the adhesive tape extends beyond the edge of the reflector.

Abstract: The present disclosure describes a protective coating for a low index material, and a process for preparing a protected low index material. The protective coating partially penetrates the pores of a low index material, providing a seal protecting the pores, and can strengthen the construction by forming a gradient in properties of the protected low index material. The present disclosure further provides a diffusing low index optical element having a protected low index material and a diffusing layer disposed on the low index material.

Abstract: Pre-aligned optical layers are stacked and arranged such that an adhesive layer, which is stacked onto the optical layers, contacts at least the uppermost layer and lowermost layer. The resulting subassemblies can be assembled into an optical display without individual handling of the layers, which reduces installation time and manufacturing costs.

Abstract: An organic particulate-filled adhesive is provided comprising ionomeric particulate dispersed in a polymer matrix containing water-soluble polymer or water-dispersible polymer. The adhesive preferably contains a plasticizer. If desired, in some formulations, the adhesive can contain additives, such as opacifying agents, skin cleansers, skin moisturizers, vitamins, and herbal extracts. The adhesive can have pressure sensitive adhesive properties, although such properties are not necessary. The adhesive can be formulated so as to be useful as a repulpable adhesive and as a cosmetic adhesive.

Abstract: A cover slip material and a method of making and using the same are provided. The material comprises (a) a light transmissible polymeric backing having first and second surfaces; (b) a tack free bonding layer disposed on the first surface of the backing, the bonding layer comprising polymers selected from the group consisting of acrylate, methacrylate, and combinations thereof; and (c) a protective coating disposed on the second surface of the backing. Upon exposure to an environmentally friendly activating solvent such as terpene, d-limonene, esters of coconut oil and aliphatic hydrocarbon blends, the bonding layer acquires tacky properties causing the cover slip to adhere to a specimen previously mounted on a microscope slide.

Abstract: A custom-formable shoe insert is disclosed that comprises (1) a conformable substrate layer, where at least a portion of the substrate layer is impregnated with a storage-stable, settable resin that set after exposure to an activator; and (2) an outer layer that is impervious to the settable resin but at least a portion of which is pervious to the activator.
