Patent number: 7127356Abstract: A single-particle optical sensor, which has high sensitivity and responds to relatively concentrated suspensions, uses a relatively narrow light beam to illuminate an optical sensing zone nonuniformly. The zone is smaller than the flow channel so that the sensor responds to only a fraction of the total number of particles flowing through the channel, detecting a statistically significant number of particles of any relevant diameter. Because different particle trajectories flow through different parts of the zone illuminated at different intensities, it is necessary to deconvolute the result. Two methods of deconvolution are used: modified matrix inversion or successive subtraction. Both methods use a few basis vectors measured empirically or computed from a theoretical model, and the remaining basis vectors are derived from these few. The sensor is compensated for turbidity. Several embodiments are disclosed employing light-extinction or light-scattering detection, or both.Type: GrantFiled: May 18, 2004Date of Patent: October 24, 2006Assignee: Particle Sizing Systems, Inc.Inventors: David F.

Patent number: 7117102Abstract: Descriptors of cohesive interactions in the solid state are calculated from a computational model of a solid state, i.e. from a small cluster of copies of the molecule of interest assembled using a molecular mechanics method.

Patent number: 7110886Abstract: A method for analyzing a multi-channel chromatogram is realized for accurately resolving overlapping peaks on a multi-channel chromatogram to permit analysis of the composition of a sample.

A quantitative spectral intensity matrix is computed, components are identified, and the identified components are quantified. Subsequently, an eigenvalue problem is solved, and the number n of components is estimated. The deconvolution and computation of the eigenvalue problem are iteratively executed until the peaks are isolated. Then, elution profiles are calculated, the components are identified, and the identified components are quantified.Type: GrantFiled: July 18, 2005Date of Patent: September 19, 2006Assignee: Hitachi, Ltd.Inventors: Masahito Ito, Kisaburo Deguchi

Patent number: 7072773Abstract: Disclosed herein is a method of analyzing three-dimensional data obtained from a chromatography/spectrometry process, in particular an LC/MS process using a two-dimensional multi-variant statistical analysis. The LC portion permits separation of analytes within a sample. The information obtained from such a procedure typically depends on retention time (Rt). As the analytes progress through the system, they enter the MS region of the LC/MS system. There they are ionized and a mass detector then detects these ionized species. The information procured from this procedure is generally reported as intensity for a corresponding m/z value. Therefore, an LC/MS system provides at least three pieces of information. Principle component analysis (PCA) is a robust method of multi-variant analysis of this type of data between different samples. However, typically, PCA analysis is performed using only two-dimensional data.Type: GrantFiled: November 16, 2004Date of Patent: July 4, 2006Inventors: Robert Stephen Plumb, Chris Lee Stumpf, Marc V.

Patent number: 7047156Abstract: The inherent smoothing in bending stiffness measurement of wood boards as occurs in the machine grading of lumber can mask the effect of knots and other local characteristics affecting structural value. Improved estimates of local (pointwise) stiffness will be useful in decisions about further processing and use of a tested board. Measured compliance is reciprocally related to measured stiffness and is the convolution of local compliance and a “span function”. Span function is specific to the bending span configuration used and can change during measurement of a board. A general procedure for computing span function, which heretofore has been known only for simple bending spans, is disclosed. A Kalman filter uses this and other available information to optimally estimate local compliance from an observed relationship between local compliance and state variables of a state-space model. Method for linear algebraic determination of local compliance also depends on span functions and is disclosed.Type: GrantFiled: December 14, 2002Date of Patent: May 16, 2006Assignee: Kierstat Systems LLCInventors: Friend K.

Patent number: 7016790Abstract: An in-line hot-wire sensor for monitoring the mixing and the flow rate of slurry is disclosed. The hot-wire sensor may include a number of resistors organized into a Wheatstone bridge, as well as a frequency-domain transform mechanism. The resistors include a hot-wire resistor that is placed in-line with the slurry after substances have been mixed to become the slurry. The Wheatstone bridge thus yields a signal that is transformed to the frequency domain by the frequency-domain transform mechanism, such as by performing a Fast Fourier Transform (FFT) of the signal. The frequency-domain transform is used to monitor the mixing of the substances into the slurry, and the flow rate of the slurry. The signal may be amplified prior to transformation to the frequency domain.Type: GrantFiled: October 23, 2002Date of Patent: March 21, 2006Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Tung-Ching Tseng, Li-Jia Yang

Patent number: 7003405Abstract: An inverse analysis method for characterizing diffusion of vapor from an underground source of volatile contaminant using data taken by an in-situ sensor. The method uses one-dimensional solutions to the diffusion equation in Cartesian, cylindrical, or spherical coordinates for isotropic and homogenous media. If the effective vapor diffusion coefficient is known, then the distance from the source to the in-situ sensor can be estimated by comparing the shape of the predicted time-dependent vapor concentration response curve to the measured response curve. Alternatively, if the source distance is known, then the effective vapor diffusion coefficient can be estimated using the same inverse analysis method. A triangulation technique can be used with multiple sensors to locate the source in two or three dimensions. The in-situ sensor can contain one or more chemiresistor elements housed in a waterproof enclosure with a gas permeable membrane.Type: GrantFiled: October 25, 2002Date of Patent: February 21, 2006Assignee: Sandia CorporationInventor: Clifford K.

Patent number: 6993455Abstract: In the method, which is to be carried out on a computer system, firstly design data of a semiconductor substrate are read in and, on the basis thereof, a mask image is generated in the form of a data structure with contact holes and with auxiliary structures on the computer system. Afterwards, contact hole biases are determined by means of an optical proximity correction method and the relevant contact holes are corrected on the basis of these contact hole biases. By means of subsequent imaging simulation of the mask image on the semiconductor substrate, undesired imaging auxiliary structures and contact holes deviating from specified tolerances on the semiconductor substrate are detected and corrected. During the imaging simulation of the mask image, a mask bias is employed in order to compensate for three-dimensional mask effects. A real mask can be produced on the basis of the mask image thus determined.Type: GrantFiled: January 5, 2005Date of Patent: January 31, 2006Assignee: Infineon Technologies AGInventors: Roderick Koehle, Reinhard Pufall

Patent number: 6959247Abstract: A system for measuring a glucose level in a blood sample includes a test strip and a meter. The test strip includes a sample chamber, a working electrode, a counter electrode, fill-detect electrodes, and an auto-on conductor. A reagent layer is disposed in the sample chamber. The auto-on conductor causes the meter to wake up and perform a test strip sequence when the test strip is inserted in the meter. The meter uses the working and counter electrodes to initially detect the blood sample in the sample chamber and uses the fill-detect electrodes to check that the blood sample has mixed with the reagent layer. The meter applies an assay voltage between the working and counter electrodes and measures the resulting current. The meter calculates the glucose level based on the measured current and calibration data saved in memory from a removable data storage device associated with the test strip.Type: GrantFiled: November 12, 2003Date of Patent: October 25, 2005Assignee: Home Diagnostics, Inc.Inventors: Gary T.
