Abstract: A fluid flow control system using flow rate changes to extract additional information from an in-line flow sensor. The system provides the ability to determine a position of a movable flow sensor element of a flow sensor by illuminating a photosensitive pixel array with a light source to create a first set of pixel intensity values introducing an abrupt change to the fluid driving pressure, illuminating the photosensitive pixel array with a light source to create a second set of pixel intensity values, and calculating the difference between the first and second sets of pixel intensity values as a function of pixel position.

Abstract: A method for manufacturing a papermaker's or industrial fabric requires the application of a polymeric resin material onto preselected locations on a base substrate using an array which deposits the polymeric resin material in droplets having an average diameter of 10? (10 microns) or more. The preselected locations, for example, may be knuckles formed by the interweaving of the yarns making up the fabric or interstices between the yarns. The purpose of such precise application of the resin is to control functional properties of the fabric, such as permeability and abrasion resistance. The polymeric resin material is set by means appropriate to its composition, and, optionally, may be abraded to provide the polymeric resin material above the surface plane of the base substrate with a uniform thickness.

Abstract: A method for manufacturing resin-impregnated endless belt structures and belt structures designed for use on a long nip press on a papermaking machine and for other papermaking and paper processing applications, requires the application of a sacrificial material onto a base substrate in a predetermined pattern in droplets having an average diameter of 10? (10 microns) or more. Polymeric resin material is then deposited on the base substrate to cover all areas except those on which the sacrificial material has been previously applied. The polymeric resin material is then set by means appropriate to its composition, and the sacrificial material removed. Optionally, the polymeric resin material may then be abraded to provide the belt with a uniform thickness, and a smooth, macroscopically monoplanar surface.

Abstract: A method for manufacturing a belt and a belt for use in the production of bulk tissue and towel, and of nonwoven articles and fabrics, requires the application of a sacrificial material onto a base substrate in a predetermined pattern which is to be imparted onto products manufactured with the belt.

Abstract: A method of determining the analyte concentration of a test sample is described. A temperature gradient is introduced in the test sample and infrared radiation detectors measure radiation at selected analyte absorbance peak and reference wavelengths. Reference and analytical signals are detected. In the presence of the selected analyte, parameter differences between reference and analytical signals are detectable. These parameter differences, having a relationship to analyte concentration, are measured, correlated, and processed to determine analyte concentration in the test sample. Accuracy is enhanced by inducing a periodically modulated temperature gradient in the test sample. The analytical and reference signals may be measured continuously and the parameter difference integrated over the measurement period to determine analyte concentration.

Abstract: The present invention is related to optical non-invasive methods and instruments to detect the level of analyte concentrations in the tissue of a subject. The spectra of mid-infrared radiation emitted from a subject's body are altered corresponding to the concentration of various compounds within the radiating tissue. In one aspect of the invention, an instrument floods a body surface of the subject, such as the subject's eye, with radiation in the mid-infrared range and measures analyte concentrations based on mid-infrared radiation reflected back to the instrument.

Abstract: A method and apparatus of determining the analyte concentration of a test sample is described. A temperature gradient is introduced into the test sample and infrared radiation detectors measure radiation at selected analyte absorbance peak and reference wavelengths. The modulation of the temperature gradient is controlled by a surface temperature modulation. A transfer function is determined that relates the surface temperature modulation to the modulation of the measured infrared radiation. Reference and analytical signals are detected. In the presence of the selected analyte, phase and magnitude differences in the transfer function are detected. These phase and magnitude differences, having a relationship to analyte concentration, are measured, correlated and processed to determine analyte concentration in the sample.
