| 20080302663 | APPARATUS AND METHOD FOR ELECTROSTATIC FILTRATION OF FLUIDS - Disclosed herein is an electrostatic fluid filtration system suitable for removing sub micron insoluble contaminants known to cause varnish from fluids such as dielectric fluids. The electrostatic fluid filtration system is configured to remove both water and other contaminants from a target fluid (e.g. a dielectric fluid) and comprises a cabinet, a computer control unit, and one or more substantially cylindrical filtration units, including at least one of a water filtration unit and an electrostatic contaminant filtration unit. In the contaminant filtration unit, the target fluid flows radially through the filtration media that is positioned between the electrode plates in a generally horizontal flow pattern. This forces the target fluid to traverse multiple energy fields in a serpentine fashion and in a single pass through the contaminant filtration unit. After flowing through each layer of the filtration media, the target fluid is discharged from the electrostatic contaminant filtration unit. | 12-11-2008 |
| 20090026082 | Methods and apparatus for measuring analytes using large scale FET arrays - Methods and apparatus relating to very large scale FET arrays for analyte measurements. ChemFET (e.g., ISFET) arrays may be fabricated using conventional CMOS processing techniques based on improved FET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense arrays. Improved array control techniques provide for rapid data acquisition from large and dense arrays. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes. In one example, chemFET arrays facilitate DNA sequencing techniques based on monitoring changes in hydrogen ion concentration (pH), changes in other analyte concentration, and/or binding events associated with chemical processes relating to DNA synthesis. | 01-29-2009 |
| 20090045063 | APPARATUS AND METHOD FOR DETECTING PARTICLES AND MICROORGANISMS USING MAGNETIC FIELD - Disclosed are an apparatus and a method for detecting particles and microorganisms using a magnetic field. The apparatus comprises a magnetic sensor that is provided at an outside of a passage pipe and measures a magnetic field induced by fluid moving in the passage pipe; an electrode that is provided in the passage pipe so as to apply electric current having a predetermined frequency to the fluid moving in the passage pipe to measure impedance; and a signal processing unit that uses an intensity of the magnetic field measured by the magnetic sensor and the impedance measured by the electrode to determine concentrations of particles and microorganisms included in the fluid. According to an embodiment of the invention, using electrical properties of the particles or microorganisms, it is possible to quantitatively analyze and to identify the particles or microorganisms in real time, to improve a measuring accuracy and to manufacture an ultra small-scaled particle and microorganism detecting apparatus having a simple structure. | 02-19-2009 |
| 20090065359 | Discrete contact MR bio-sensor with magnetic label field alignment - The invention describes a family of sensors for assaying macro-molecules and/or biological cells in solution. Each sensor has the form of a well (a hollow cylinder having a floor but no lid) or a trench whose walls comprise a plurality of GMR or TMR devices. Suitably shaped magnets located below each well's floor pull labeled particles into the well/trench and up against the inner wall where a field gradient orients them for optimum detection. Any unattached labels that happen to also be in the well/trench are removed through suitably sized holes in the floor. | 03-12-2009 |
| 20100051463 | Water Reclamation Systems and Methods - Water treatment, reconditioning, and reclamation systems and methods are described. The systems utilize two treatment vectors. The first treatment vector is created by flowing electrical current through a first conductive rod. The second treatment vector is created by delivering a magnetic pulse by way of a second conductive rod. Water to be treated is exposed to the two vectors simultaneously, which is accomplished by creating relative motion between the conductive rods and the water, either by moving the conductive rods or by moving the water. The electric current of the first treatment vector and the voltage and frequency of the magnetic pulse of the second treatment vector may be reduced as the treatment process proceeds. During treatment, total dissolved solids (TDS) rise and congeal at the top of the water. The congealed TDS are removed from the water. An additional filtering process may be applied. | 03-04-2010 |
