Abstract: A lightweight, flexible, plastic substrate used to construct displays, including flat panel displays, to package materials and for electro luminescence lamps is coated with at least one layer, such that the substrate has desired barrier and electrode characteristics. The display medium of the flat panel display is protected from oxygen and moisture in order to avoid degradation with the coating. The layer with barrier and electrode characteristics has both a low enough resistance to function as an electrode for the display, and low oxygen and moisture permeability. For lower permeability and/or higher conductivity, multiple alternating layers of barrier materials and conductive materials are applied. The barrier material includes at least one of a thin metallic film, an organic polymer, a thin transparent dielectric, a thin transparent metal nitride, and a thin transparent conductive oxide.

Abstract: A device or an enclosed area that can cause or is sensitive to electromagnetic interference (EMI) is shielded by at least partially surrounding the device or the area with a visible light-transmissive film comprising a flexible support, an extensible visible light-transmissive metal or metal alloy layer and a visible light-transmissive crosslinked polymeric protective layer, and optionally connecting at least one grounding electrode to the metal or metal alloy layer. The film has reduced susceptibility to fracture or corrosion compared to commercially available EMI shielding films, especially when bent or deformed.

Abstract: Electrically conductive films comprising a flexible support, an extensible metal or metal alloy layer, and a crosslinked polymeric protective layer have at least one permanently deformed curved region. The films can be light transmissive and can have regions of compound curvature, and the metal or metal alloy layer can be substantially continuous. The films have reduced susceptibility to fracture or corrosion compared to commercially available electromagnetic interference (EMI) shielding films.

Abstract: An electrically conductive film contains electrically connected first and second visible light-transmissive metal or metal alloy layers separated by a visible light-transmissive crosslinked polymeric layer. The film can be joined or laminated into glazing (especially non-planar vehicular safety glazing) with reduced likelihood that the metal or metal alloy layers will be damaged or distorted. The film also can transparently shield a device that can cause or is sensitive to electromagnetic interference with reduced likelihood that the metal or metal alloy layers will fracture.

Abstract: Color shifting retroreflective articles can provide features such as decorative effects, evidence of tampering, security authentication or positional information. In some embodiments, the color shifting retroreflective article includes a layer of microspheres, and a reflective coating that is disposed in optical association with the layer of microspheres. The reflective coating includes a spacer layer disposed between a semitransparent first reflective layer and a second reflective layer. The first reflective layer includes a reflective layer disposed adjacent the layer of microspheres. At least one layer of the reflective coating includes a non-uniform thickness associated with each of a plurality of microspheres such that light incident on the article from a first direction is retroreflected at a first color and light incident on the article from a second direction is retroreflected at a second color visibly different from the first color.

Abstract: A control system for obtaining maximum power output from electrical generating water pumping, flywheel storage and like systems comprising a wind-driven prime mover coupled to an electrical generator over an extended range of wind velocities is described. The maximum electrical output power is obtained by synchronizing the speed of the generator, and hence the speed of the prime mover, with the maximum power output of the prime mover. Since the maximum output power of a wind-driven prime mover is proportional to the third power of the wind velocity, and is a function of an angular velocity-dependent power coefficient, means are provided for detecting the angular velocity of the prime mover and generating a signal proportional to the cube of said wind velocity.
