| 20090167328 | FLUID MEASURING APPARATUS - The invention provides a fluid measuring apparatus, which includes a collector, a sensing circuit, and an electrochromic device electrically connected to the sensing circuit. When the concentration of a fluid flowing through the collector and between the sensing circuit varies, the color of the electrochromic device changes accordingly. Further, the electrochromic device includes an electrochromic material, and the sensing circuit includes a first electrode and a second electrode, wherein the first and the second electrodes are disposed in the collector and the electrochromic material is disposed on the first electrode. When the concentration of an electrolytic solution flowing between the first electrode and the second electrode varies, the color of the electrochromic material changes accordingly. | 07-02-2009 |
| 20130063168 | Nanopore Molecule Detection System And Molecule Detection Method Based On Potential Measurement Of Insulated Conductive Thin Layer - A particle detector includes: a conductive nanolayer; insulating nanolayers attached to both sides of the conductive nanolayer; a nanopore formed to penetrate the conductive nanolayer and the insulating nanolayers so as to provide a migration path for a sample particle; a power supply unit configured to apply an electric field between both ends of the nanopore so as to apply a potential to the conductive nanolayer; and an electric signal measuring unit electrically connected to the conductive nanolayer and configured to measure the potential change in the conductive nanolayer induced by the sample particle as the sample particle migrates through the nanopore. The particle detector is capable of detecting a particle with high signal-to-noise ratio and resolution, scanning a sample without mechanical motion of the conductive nanolayer and analyzing DNA base sequences. | 03-14-2013 |
| 20140266267 | CONDUCTIVITY MEASUREMENT OF FLUIDS - A product is provided into a first end of a conduit so that the product flows toward a second end of the conduit. The conduit may include a first pair of probes attached at a first location and a second pair of probes at a second location. The product's conductivity in the conduit at the first location is monitored using the first set of probes, and the product's conductivity at the second location is monitored using the second set of probes. An marker material is introduced into an entry port of the conduit so that the marker material flows with the product. The marker material's conductivity is different than the product's conductivity. At a first time, the first set of probes detects the conductivity of the product has changed due to the introduction of the marker material, and at a second time, the second set of probes also detects such change. | 09-18-2014 |
| 20150346129 | TOMOGRAPHIC DETERMINATION OF MULTIPHASE FLOWS IN PIPES AND/OR LIQUID/FROTH INTERFACES IN PROCESS TANKS USING HIGH SPEED MULTIPLEXED ELECTRICAL IMPEDANCE SENSING - Apparatus is provided featuring a signal processor or processing module configured at least to: receive signaling containing information about coded and multiplexed voltages measured across pairs of electrodes in an array of electrodes configured in relation to a fluid processing structure, including a pipe, tank, vessel, vat or container, having a process fluid therein; and determine using a tomographic signal processing algorithm a tomographic indication of the process fluid, based at least partly on the signaling received. The signal processor module may be configured to provide corresponding signaling containing information about the tomographic indication of the process fluid. The tomographic indication includes a 2D or 3D image or visualization of the process fluid, including an analysis of mixing in multiphase flows, liquid interfaces or liquid-froth layers detected in the process fluid. | 12-03-2015 |
