Abstract: Applicants have discovered that electrostatic discharge (ESD) may, in some circumstances, result in current densities sufficient to ignite unprotected reactive composite materials. They have further discovered that a reactive composite material (RCM) can be protected from ESD ignition without adversely affecting the desirable properties of the RCM by the application of conducting and/or insulating materials at appropriate locations on the RCM. Thus ESD-protected RCM structures can be designed for such sensitive applications as ignition of propellants, generation of light bursts, and structural materials for equipment that may require controlled self-destruction.

Abstract: A combination of filters for filtering selected wavelengths of electromagnetic radiation is provided on a transparent substrate such as a plastic film or glazing of a window. The combination of filters prevents or attenuates the passage of wavelengths through the substrate which would pose a security risk. The combination of filters is useful to prevent unauthorized data collection and information exchange from or within buildings or otherwise prevent such unauthorized data collection and information exchange from, for example, computer monitors or screens, personal digital assistance, and local area networks. The substrate with the combination of filters may be in the form of a bag or a tent.

Abstract: A heat reflecting fenestration composite is provided which includes in sequence: (a) a substantially transparent substrate; (b) a first outer dielectric layer; (c) an infrared reflecting metal layer; (d) a color correcting metal layer comprising a metal different from the infrared reflecting metal layer; (e) a protective metal layer comprising a metal different from the infrared reflecting metal layer and different from the color correcting layer; and (f) a second outer dielectric layer. The dielectric layers are typically indium oxide, indium zinc oxide, indium tin oxide or mixtures thereof. Preferably, the composite also includes additional layers of infrared reflecting metal layer, color correcting metal, protective metal and dielectric. Also preferably, the composite comprises a top layer of glass or transparent polymeric plastic. The infrared reflecting metal layer is typically silver, gold, copper or alloys thereof.
