20130003911 | METHODS AND APPARATUS FOR IN-PIXEL FILTERING IN FOCAL PLANE ARRAYS - Digital focal plane arrays (DFPAs) with multiple counters per unit cell can be used to convert analog signals to digital data and to filter the digital data. Exemplary DFPAs include two-dimensional arrays of unit cells, where each unit cell is coupled to a corresponding photodetector in a photodetector array. Each unit cell converts photocurrent from its photodetector to a digital pulse train that is coupled to multiple counters in the unit cell. Each counter in each unit cell can be independently controlled to filter the pulse train by counting up or down and/or by transferring data as desired. For example, a unit cell may perform in-phase/quadrature filtering of homodyne- or heterodyne-detected photocurrent with two counters: a first counter toggled between increment and decrement modes with an in-phase signal and a second counter toggled between increment and decrement modes with a quadrature signal. | 01-03-2013 |

20080230388 | Rapid Homogeneous Immunoassay Using Electrophoresis - The present invention concerns methods, compositions and apparatus for detection and/or determination of concentration of target molecules. In preferred embodiments the methods comprise allowing target molecules to form a complex with a first binding agent conjugated to a detection molecule and a second binding agent conjugated to a capture molecule, allowing the complex to further bind to an essentially uncharged polymer capable of binding to the capture agent, and performing a vertical gradient electrophoresis to separate the complex from unbound target, first and second binding agents and polymer. The intact complex is concentrated by electrophoresis at a stacking layer and the detection molecule is detected and/or quantified. Because the complex contains a very high mass to charge ratio, it becomes essentially immobile at the stacking layer, while unbound components migrate through the stacking layer and are separated from the complex. This provides a very rapid and sensitive assay that can detect very low concentrations of target molecules in short time. | 09-25-2008 |
20100203578 | APPARATUS AND METHODS FOR SEPARATING AND ANALYZING COMPONENTS IN FLUIDS - Provided are methods and devices for separating particulate analytes or aggregates of analytes from a fluid, after the separation medium of the device is saturated with the fluid. The endpoint indicating completion of the separation is determined by saturation; therefore, no precise metering of the fluid sample is necessary. The separated analyte of interest can be detected, quantitated or its migration measured in the separation medium. The measured property of the analyte can then be correlated with a parameter of interest. In some embodiments, the device can be marked to directly read the value of the parameter of interest. In one embodiment, the fluid is blood and the device includes a volumetric capillary reservoir for collecting the blood, a separation paper or indicator strip, and graduations for correlating the migration of red blood cells with hematocrit or hemoglobin concentration. The interface of red blood cells and plasma creates a readable marking that corresponds to percent hematocrit and can be read from the graduations. | 08-12-2010 |
20100267065 | APPARATUS AND METHODS FOR ANALYZING FLUID VARIABLES - Methods and devices for analyzing fluid variables such as viscosity, surface tension, analyte concentration, the presence of particulates or aggregates are provided. The devices analyze fluid variables by measuring cessation of fluid flow through the medium or a change in flow rate due to an inherent property of the fluid variable, or due to a modification of the fluid variable as the fluid migrates through the medium. One lateral flow device provided analyzes a fluid variable in a sample by measuring relative rates of capillary flow down two or more converging arms of a common element of porous media, such as filter paper, in which at least one of the arms has been modified by the addition of flow-modifying agents which affect the flow rate in response to the concentration of the analyte. The fluid fronts will converge at a position determined by their relative flow rates, which is thus indicative of a fluid variable, such as analyte concentration, in the sample fluid. Another lateral flow device provided herein analyzes fluid variables in a sample by measuring relative rates of capillary flow down two or more arms of a common element of porous media, such as filter paper, in which at least one of the arms has been modified by the addition of flow-modifying agents which affect the flow rate in response to the concentration of the analyte. The relative distance at completion of the fluid fronts from the sample introduction point is determined by their relative flow rates, which is thus indicative of the fluid variable, such as concentration of analyte, in the sample fluid. Yet another lateral flow device provided herein qualitatively measures fluid variables in a sample by detecting changes in the rate of the capillary flow of the sample fluid along a path through an element of porous media, or through multiple elements of porous media which are in serial contact with each other, in which the sample and/or the fluid path has been modified by the addition of flow-modifying agents which cause flow to stop in the presence of the fluid variable, such as a particular concentration of analyte. | 10-21-2010 |
