Patent number: 10175209Abstract: Apparatus and method measure the flow rate of fluid for use in calibrating fraction collection in a chromatography system. An injector inserts a detectable substance into a flow of fluid. A first detector, disposed in a path of the flow of liquid with the substance, produces a signal in response to detecting the substance in the flow of fluid. A second detector, disposed downstream from the first detector in the path of the flow of fluid with the substance, produces a signal in response to detecting the substance in the flow of fluid. A computing system receives each signal produced by the first and second detectors upon detecting the substance in the flow of fluid, and computes a volumetric flow rate of the flow of fluid based on a time interval between the signals and a volume of the path between the first and second detectors.Type: GrantFiled: November 2, 2015Date of Patent: January 8, 2019Assignee: WATERS TECHNOLOGIES CORPORATIONInventors: Joshua A. Burnett, James Usowicz, Marc Lemelin, Lucas O. Tiziani, Aaron Lebeau

Patent number: 10048242Abstract: A device installable into a tap to detect the presence of one or more types of contaminants in the tap water. When the tap is operated, a sample chamber fills with the tap water, such that one or more electronic receivers are capable of detecting the presence of contaminants. Preferably, at least one of the one or more electronic receivers is a photometric sensor for detecting absorption of ultraviolet (UV) light in the 250 nm to 300 nm range. A UV254 LED can be activated when water fills the sample chamber, and a measurement circuit calculates Total Organic Carbon (TOC) by correlation with UV254 absorbance. The device can transmit contamination data, including, but not limited to TOC levels, to a remote apparatus for remote monitoring of the tap water.Type: GrantFiled: June 6, 2016Date of Patent: August 14, 2018Assignee: Shenzhen Yimu Technology Co., Ltd.Inventors: Gang Chen, Zhiqiang Li

Patent number: 9868648Abstract: This disclosure is directed to the regulated injection of a chemical(s), solution(s) or material(s) hereafter referred to as chemicals into stormwater runoff, other surface waters or other fluid streams to promote the removal of a pollutant(s) or to alter the properties of the water. Specifically, and depending upon the types of chemicals injected, the physical, chemical and/or biological properties of the water can be altered. The invention provides a passive system to alter stormwater runoff or other surfaces. The system may be deployed at a remote site, such as a construction site, and implemented with minimal or zero external power requirements.Type: GrantFiled: May 24, 2013Date of Patent: January 16, 2018Inventors: Jason Robert Vogel, Daniel Eugene Storm, Billy J. Barfield, Wayne Ray Kiner, Karl Michael Garbrecht

Patent number: 9853618Abstract: A transimpedance amplifier circuit (1) includes an amplifier (22) that amplifies a received signal, an automatic gain control (AGC) circuit (2) that controls the amplification gain of the amplifier by a first time constant in accordance with the level of the received signal, and a first selection circuit (25) that selects the first time constant from a plurality of predetermined values. This can simultaneously implement a short time constant of an AGC function necessary to instantaneously respond to a burst signal and a long time constant of the AGC function necessary to obtain a satisfactory bit error rate (BER) characteristic in a continuous signal by an inexpensive and compact circuit arrangement.Type: GrantFiled: September 26, 2014Date of Patent: December 26, 2017Assignees: NIPPON TELEGRAPH AND TELEPHONE CORPORATION, NTT ELECTRONICS CORPORATIONInventors: Hiroshi Koizumi, Masafumi Nogawa, Masatoshi Tobayashi, Masahiro Endo

Patent number: 9841407Abstract: A liquid chromatograph analysis method and a liquid chromatograph minimize analysis time when performing analyses by switching columns and mobile phases. Liquid chromatograph 100 for performing a plurality of analyses according to a schedule table includes: mobile phase switching sections 15, 16 for switching a plurality of mobile phases to select a mobile phase to be used in analysis; column switching sections 31, 33 for switching a plurality of columns 32a-32f to select a column to be used in analysis; and control section 60 including memory 61 for storing an equilibration time of each of the plurality of columns 32a to 32f and an equilibration controller 66 for controlling column equilibration. If used columns or used mobile phases are different between two consecutively executed analyses, equilibration controller 66 equilibrates a column used in the later of the two analyses over an equilibration time read out from memory 61.Type: GrantFiled: March 3, 2015Date of Patent: December 12, 2017Assignee: SHIMADZU CORPORATIONInventor: Hiroshi Ohashi
