|20100278441||Differential wavelength imaging method and system for detection and identification of concealed materials - A method and system for detection and identification of concealed materials, is provided, wherein a dark image and two or more NIR sample images are taken at two or more key wavelengths or bands of wavelengths corresponding to peaks and/or valleys in the NIR spectra of known materials, and differential wavelength imaging processes are used to produce a a differential wavelength image based on therein. The differential wavelength image is then analyzed/processed so as to detect any materials concealed on the target of interest, such as a human or piece of baggage, by calculation of pixel intensity values in the image and identification of distinctive pixel values. Then, via various methods, the distinctive pixel values of the detected materials are compared to a data set of known wavelengths related to known materials, such as explosives and other contraband. Correspondence thereof results in an accurate identification of the concealed material(s).||11-04-2010|
|20100178203||Non-Invasive Colorimetric-Based Infection Detector And Infection Detecting Bandage - A non-invasive, calorimetric infection detector is provided, comprised of a substrate, and one or more indicator compositions disposed upon or incorporated therein. These indicator compositions exhibit a persistent change color when exposed to gaseous oxides of nitrogen and acids formed therefrom, providing a means of detecting NO production in a wound, which has been found to occur at a high level at the onset of infection in a wound. In addition, a bandage is provided, comprised of the detector, as well as a porous portion, and preferably a hydrophobic barrier layer to protect the detector from contamination by water and other fluids draining from the wound. The non-invasive, calorimetric infection detector, and bandage containing same, can be utilized to provide a convenient, easily utilized colorimetric means of detecting the onset of wound infection, thereby enabling caregivers to effectively and timely treat infections.||07-15-2010|
|20100032583||Optical Chemical Sensor Feedback Control System - An optical chemical sensor feedback control system is provided comprised of a luminescent sensing film, an optical processor adjacent the sensing film capable of sinusoidally photoexciting the luminescent sensing film and detecting the luminescent emission resulting therefrom, and a computer control means executing a computer program, in communication with the optical processor. The computer control means is operable to control the magnitude of the photoexcitation of the luminescent sensing film, wherein the computer control means receives data regarding the luminescent emission resulting therefrom, analyzes same, and determines the magnitude and phase shift of the luminescence relative to the photoexcitation. Further, the system herein is operable to determine the status of the sensing film, and adjust the magnitude of photoexcitation thereof based on same. In addition, the system, via the optical processor positioning means, is operable to adjust the physical position of the optical processor and/or light source in relation to the sensing film, based on data received from the computer control means.||02-11-2010|
|20080286155||Multilayered optical sensing patch and retaining plug therefor - A multilayered optical sensing patch, for the measurement of conditions, such as pH, oxygen level, etc, within containers, is provided. The multilayered optical sensing patch of the present invention is comprised of a heat sealable polymer substrate layer, and a polymeric sensing membrane later attached thereto. The polymer sensing membrane layer is formed of a porous polymer support membrane, and an optical sensing composition (comprising a reactive indicator) covalently bonded thereto. The heat sealable polymer substrate layer is capable of being securely bonded to the inner layer of bioreactor bags, as well as the porous polymer support substrate layer. Further, the porous polymer support membrane layer provides a firm supporting structure for the polymeric sensing layer, thereby protecting the optical sensing composition disposed therein from degradation/damage.||11-20-2008|
