Patent number: 7957077Abstract: A molded optical filter is provided having effective filtering of energy emissions at an optical density (OD) of greater than 4 in three energy emission bands corresponding to the wavelengths of laser emissions while preserving the wearer's ability to differentiate and recognize colors and having a pleasing overall color. The selective optical filter is a moldable polymer filter that has three dyes therein to produce sharp notch filtering ranges at about 530 nm, 700 nm and 1060 nm and a fourth color balance dye therein to adjust the overall color of the filter making it more pleasing and desirable to the wearer.Type: GrantFiled: January 5, 2010Date of Patent: June 7, 2011Assignee: Sperian Eye & Face Protection, Inc.Inventors: Marianne Krieg-Kowald, Mark McLear

Patent number: 7374804Abstract: An optically readable media (10) has an information-encoding layer (16) and at least one color-forming layer (12) that embodies an optical readout-limiting mechanism. In a first embodiment the at least one color-forming layer contains an additive that does not interfere with the optical readability of the media for a duration of a readout period. The additive, upon exposure to a source of optical radiation that is suitable for reversing the color-forming layer from an optical readout inhibiting state to an optical readout enabling state, undergoes a transformation that maintains the color-forming layer in the optical readout inhibiting state. More specifically, exposure to the source causes the color-forming layer to photobleach and the additive to oxidize, where the oxidation of the additive permanently inhibits the optical readability of the media. The additive may be a leuco dye.Type: GrantFiled: August 23, 2005Date of Patent: May 20, 2008Assignee: Flexplay Technologies, Inc.Inventor: Marianne Krieg-Kowald

Publication number: 20050058800Abstract: Methods and apparatus are provided for making an optically readable media unreadable and tamper-resistant. A method is disclosed for making an optically readable media unreadable, as is a media that operates in accordance with the method. The method has steps of (a) providing the media with a readout surface layer that is non-flat (i.e., textured in some way, such as by embossing, scratching, depositing a non-planar layer or regions, such as droplets) and that inhibits optical readout of the media; (b) applying a coating layer to the non-flat surface layer to smooth the non-flat surface and to enable optical readout of the media; and, after an initiation of a readout period, (c) removing the coating layer so as to expose the non-flat readout surface layer, thereby inhibiting optical readout of the media. Preferably, the coating layer is substantially index matched to the readout surface layer.Type: ApplicationFiled: June 25, 2004Publication date: March 17, 2005Applicant: Flexplay Technologies, Inc.Inventors: Nabil Lawandy, Charles Zepp, Andrei Smuk, Marianne Krieg-Kowald

Publication number: 20020172143Abstract: An optically readable media and packaging therefor, where the media includes a material that over time undergoes at least one of a chemical change or a physical change to render unreadable the optically readable media. The media is sealed within the packaging with a source of a chemical compound that inhibits the change, and the media is also sealed within the packaging with a getter of the chemical compound that over time absorbs said chemical compound, or which a substance that over time renders unreactive a reactive chemical compound. In a further embodiment the media is sealed within the packaging with a getter of a chemical compound that promotes the change. In this case the getter absorbs the chemical compound until saturated with the chemical compound, after which the concentration of the chemical compound increases until the media is rendered unreadable. As non-limiting examples, the chemical compound may be NMP, DMF, acetone, or HCl.Type: ApplicationFiled: December 10, 2001Publication date: November 21, 2002Inventors: Nabil M.
