摘要： A method is disclosed for sorting textiles, as is a system that operates in accordance with the method. The method includes steps of (a) providing a plurality of textiles to be sorted, each of the textiles comprising a portion that includes an electromagnetic radiation emitting and amplifying material; for each textile, (b) illuminating at least the portion with laser light that exceeds a threshold fluence; (c) detecting a narrow band laser-like emission of at least one wavelength from the portion in response to the step of illuminating; and (d) sorting the textiles based on the detected laser-like emission. In one embodiment the textile has at least one stitched-in thread, the thread comprising a substrate material and the electromagnetic radiation emitting and amplifying material in combination with scatterers for providing the laser-like emission. In another embodiment the textile has an applied patch containing the electromagnetic radiation emitting and amplifying material. In this case the scatterers can comprise the material of the textile either alone or in combination with the material of the patch. The emission wavelength(s) are selected so as to encode desired information, such as a customer identification, a date the textile was first placed into service, an identification of the vendor of the textile, an identification of the type and/or size of the textile, etc.

摘要： A structure generates electromagnetic radiation having at least one wavelength selected for activating a photosensitive substance that is applied to a tissue to be treated. The structure is particularly useful for photodynamic therapy (PDT) applications. The structure includes a body of material, such as a polymer filament, band, or substrate, that contains a gain medium. The gain medium in turn contains a substance (such as dye molecules) for generating a stimulated emission that includes the at least one wavelength when excited by a pump wavelength, and a plurality of scattering sites (such as scattering particles) for scattering the stimulated emission to provide a narrow band emission at the at least one selected wavelength. The narrow band emission in turn activates the photo-sensitive therapeutic substance.

摘要： Optical media having markings that are non-interfering, or substantially non-interfering with readout of data from the optical media are disclosed. The optical media make use of certain formulations of color forming coatings described herein. Protective coatings used to enhance the color forming coatings are also presented. Methods for incorporating the coatings into the optical media are included. In preferred embodiments, the marking is formed in a photosensitive coating that is applied to the optical media, and then cured with a first light. A second light, having a substantially separate band of wavelengths from the first light, is used to image a marking into the coating. The coating is robust to many external influences, such as ambient environmental conditions, and physical wear.
