20090022462 | FIRE RESISTANT JACKET COMPOSITION FOR ELECTRICAL COAXIAL AND FIBER OPTIC CABLE - Zeolite-containing polyvinyl chloride containing compositions that are useful as the insulation for plenum cables are disclosed. A zeolite, either natural or synthetic, can satisfactorily replace either part or all of the molybdenum compound, particularly ammonium octamolybdate, in low smoke polyvinyl chloride based plenum compositions. Ion-exchanged zeolites, such as the zinc ion-exchanged zeolite can also be used. Zeolites are especially useful in lead-free Low Smoke PVC compositions. Because the cost of zeolite is only a fraction of the cost of the molybdenum compounds currently used in plenum cable compositions, this will dramatically reduce the cost of these materials. | 01-22-2009 |

20100152352 | SUBSTRATES COATED WITH FLAME RETARDANT COMPOSITIONS BASED ON ORGANIC POLYMERS AND ZEOLITES - Substrates, which may be either flexible or rigid, are coated with a flame retardant composition containing an organic polymer, a filler and a zeolite. Good flame retardant properties are obtained even where the composition contains low levels of conventional flame retardant additives such as antimony compounds, brominated compounds and zinc compounds. The flame retardant composition may also be used to adhere different substrates together. | 06-17-2010 |
20110124987 | Methods for Measuring Changes in Optical Properties of Wound Tissue and Correlating Near Infrared Absorption (FNIR) and Diffuse Reflectance Spectroscopy Scattering (DRS) With Tissue Neovascularization and Collagen Concentration to Determine Whether Wound is Healing - Optical changes of tissue during wound healing measured by Near Infrared and Diffuse Reflectance Spectroscopy are shown to correlate with histologic changes. Near Infrared absorption coefficient correlated with blood vessel in-growth over time, while Diffuse Reflectance Spectroscopy (DRS) data correlated with collagen concentration. Changes of optical properties of wound tissue at greater depths are also quantified by Diffuse Photon Density Wave (DPDW) methodology at near infrared wavelengths. The diffusion equation for semi-infinite media is used to calculate the absorption and scattering coefficients based on measurements of phase and amplitude with a frequency domain or time domain device. An increase in the absorption and scattering coefficients and a decrease in blood saturation of the wounds compared to the non wounded sites was observed. The changes correlated with the healing stage of the wound. The methodologies used to collect information regarding the healing state of a wound may be used to clinically assess the efficacy of wound healing agents in a patient (e.g., a diabetic) and as a non-invasive method | 05-26-2011 |
20110208063 | NON-CONTACT FREQUENCY DOMAIN NEAR INFRARED ABSORPTION (fNIR) DEVICE FOR ASSESSING TISSUE DAMAGE - A device for measuring the progress of healing of a wound over time includes at least one diode laser source that provides respective input wavelengths into at least one source fiber, a first optical switch that sequentially switches wavelengths among the respective input wavelengths into the at least one source fiber, a probe that does not touch the wound dunng use, the probe including the at least one source fiber and at least two detectors spaced thereon, an optical system that provides source light from the at least one source fiber to the wound and that detects light scattered by the wound surface and provides the scattered light to the detectors, and a processing unit responsive to outputs of the detectors for providing at least four independent measurements for calculation of an absorption coefficient/Ia and a scattering coefficient/I's of the light by the wound | 08-25-2011 |
