    摘要: 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. In one embodiment the step of removing includes a step of evaporating at least one component material of the coating layer, while in another embodiment the step of removing includes a step of subliming at least one component material of the coating layer. A method is also disclosed for discouraging tampering with a readout-limiting mechanism of an optically readable media, as is a media that is constructed so as to operate in accordance with the method. In this embodiment the method has steps of: (a) providing the media with at least one layer that embodies the readout-limiting mechanism; (b) providing a textured surface that forms part of a layer that underlies the at least one layer, where the textured surface inhibits optical readout of the media; and (c) applying a coating layer over the textured surface to smooth the textured surface and to enable optical readout of the media, wherein removal of the coating layer exposes the textured surface thereby inhibiting optical readout of the media. The disk can be packaged in a sealed container with a source of an agent that inhibits transport of a volatile species from the color forming layer or from a layer that sublimates, wherein the onset of the limited play period coincides with the opening of the container.

    摘要: 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.

    摘要: 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. In one embodiment the color-forming layer is comprised of 3-[2,2-bis(4-diethylaminophenyl)vinyl]-6-dimethylaminophthalide and the additive is comprised of benzoyl leucomethylene blue. In a further embodiment the additive is placed into a protective layer (18) that overlies the color-forming layer.
