Patent number: 6951681Abstract: A method for optically coupling a thermoplastic material to an outer surface layer of an organic, dielectric, optical film and the resulting optical filter. Initially, a dielectric film is selected that includes (i) repeating optical layers of at least two polymers having different refractive indexes from each other, (ii) an exterior film surface, (iii) a refractive boundary along the exterior film surface, and (iv) a delamination threshold based on total thermal energy delivered to the film. A thermoplastic material which is miscible with the exterior film surface is fused to the refractive boundary with thermal energy below the delamination threshold to form a polydisperse region having a higher optical transmission than the refractive boundary. Add-on filters in the form of hardcoat layers, anti-reflection layers, holograms, metal dielectric stacks and combinations of these may be combined with the thermoplastic-film construct.Type: GrantFiled: December 12, 2003Date of Patent: October 4, 2005Assignee: GENTEX CorporationInventors: Scott M. Hartley, Robert A. Sallavanti

Patent number: 6933059Abstract: A film material for use in packaging electrostatically sensitive components and corrosion sensitive components. The film material includes a static dissipative polymer attached to a first moisture barrier which in turn is attached to a second moisture barrier. The second moisture barrier has a low charge retaining coating. The first and second moisture barriers are separated by dielectric. Moisture barriers are formed by either a metal foil, or a metallized polymer in which the metallization thickness is at least 178 Angstroms thick. The metal of the second moisture barrier is in contact with the low charge retaining coating. The low charge retaining coating together with the metal in the second moisture barrier has a surface conductivity between 10?3 and 10?7 Siemens.Type: GrantFiled: May 7, 1999Date of Patent: August 23, 2005Assignee: SCC Products, Inc.Inventor: Brent Beamer
