Publication number: 20110180768Abstract: A UV camouflaging substance, in the form of a solid, powder, paste, film, or liquid, can be applied to objects such as fabrics to match the ultraviolet reflectivity of the objects with their immediate surroundings. Embodiments are transparent to visible and IR light, and can be applied without changing the visible appearance of the objects. Other embodiments visibly match the surrounding environment, such as a white substance used near snow. Different embodiments can be layered on top of each other to form UV camouflage textures and to adapt to changing environments. Some embodiments can be washed off, to avoid a build-up of camouflage layers. Embodiments include UV-interactive micro- or nano-particles suspended in a binding agent which transmit, reflect, absorb and/or scatter ultraviolet rays. Some particles are absorbent, while others are approximately one-quarter wavelength thick, and suppress UV light by inducing half-wavelength phase shifts between light reflected from opposing surfaces.Type: ApplicationFiled: November 15, 2010Publication date: July 28, 2011Inventor: Reed F.

Publication number: 20110143109Abstract: The present invention relates to a material with high visibility to humans and low visibility to deer and other dichromatic animals, and a method for making the same. The color “Safety Orange” emits and reflects light at the long visible wavelengths of 595-605 nm, which are conspicuous to humans and largely unseen by dichromates.

Publication number: 20090224218Abstract: This invention provides, in one aspect, a procedure to use optically transparent nanocrystalline quantum dots to absorb UV light. This absorption process leads to an energy transfer to a chemically bound and chelated lanthanide ion that may emit light in either the visible spectrum (400-700 nm) or in the near infrared (700-1600 nm). This invention also provides methods for the use of these taggant materials in inks and aerosols used to disperse the taggant.Type: ApplicationFiled: October 30, 2008Publication date: September 10, 2009Inventors: George M. Williams, David M. Schut

Patent number: 7582231Abstract: The present invention is directed to a composite having tunable radiation diffracting properties which includes a flexible, water-free polymeric matrix and a crystalline colloidal array of particles having a lattice spacing, the array being embedded in the polymeric matrix and the lattice spacing changing responsive to stress applied to the polymeric matrix, thereby causing the radiation diffracting properties to change, wherein the polymeric matrix, the lattice spacing and the radiation diffracting properties all return to their original state essentially immediately upon removal of the stress. The present inventive composite is preferably made by a process, which involves forming a preliminary hydrogel polymerized crystalline colloidal array (PCCA), dehydrating the PCCA, and then forming a final, encapsulating polymeric matrix.Type: GrantFiled: September 16, 2005Date of Patent: September 1, 2009Inventors: Stephen H. Foulger, Ping Jiang

Publication number: 20090068474Abstract: A coating for reducing interaction between a surface and the environment around the surface includes an alkali silicate glass material configured to protect the surface from environmental corrosion due to water or moisture. The alkali silicate glass material is doped with a first element to affect various forms of radiation passing through the coating. The electromagnetic radiation is at least one of ultraviolet, x-ray, atomic (gamma, alpha, beta), and electromagnetic or radio wave radiation. The coating may also be used to protect a solar cell from the environment and UV rays while retransmitting received light as usable light for conversion into electrical energy. The coating may also be used to prevent whisker formation in metal finishes of tin, cadmium, zinc, etc.Type: ApplicationFiled: September 29, 2008Publication date: March 12, 2009Inventors: Nathan P. Lower, Alan P. Boone, Ross K. Wilcoxon, David D. Hillman
