Publication number: 20230417717Abstract: A calibration method includes receiving data characterizing a first pressure broadening coefficient, a second pressure broadening coefficient and a third pressure broadening coefficient of the target gas absorption associated with a first background gas, a second background gas and a third background gas, respectively. The method further includes, determining a molar ratio associated with the second background gas and the third background such that an effective pressure broadening coefficient associated with a target gas mixture including the second background gas and the third background gas mixed at the determined molar ratio is within a predetermined threshold of the first broadening coefficient. The target gas mixture further includes a target gas. The method also includes calibrating a gas analyzer using the target gas mixture to replace the calibration of the target in the first background gas.Type: ApplicationFiled: June 23, 2022Publication date: December 28, 2023Inventors: Chong Tao, Aniruddha S. Weling

Publication number: 20220107289Abstract: A method includes receiving data characterizing a speed of an acoustic signal through a gas mixture in a pipe. The speed of the acoustic signal can be detected by an ultrasonic flow meter coupled to the pipe. The method also includes receiving data characterizing a concentration of one or more inert gases in the gas mixture detected by an inert gas analyzer. The method further includes determining, based on the received data characterizing the speed of the acoustic signal and the received data characterizing the concentration of the one or more inert gases in the gas mixture, a net heating value of the gas mixture. The method also includes adjusting a processing of the gas mixture based on the determined net heating value.Type: ApplicationFiled: October 15, 2021Publication date: April 7, 2022Inventors: Chong Tao, Dan Johnson, Aniruddha S. Weling, Tony Kowal, Yufeng Huang

Publication number: 20220018695Abstract: A method of in situ ultrasonic flow meter validation includes receiving data characterizing first signal diagnostics and data characterizing a first speed of a first acoustic signal through a gas mixture along a first path in a pipe. The first speed of the first acoustic signal is detected by a first channel of an ultrasonic flow meter including a first pair of transducers that are separated by a first path length of the first path. The gas mixture is configured to flow along a flow path in the pipe. The method also includes determining a status associated with the ultrasonic flow meter based on the data characterizing the first signal diagnostics and/or a difference between the first speed of the first acoustic signal and an independently calculated speed of sound. The speed of sound is calculated based on one or more properties of the gas mixture.Type: ApplicationFiled: November 27, 2019Publication date: January 20, 2022Inventors: Yufeng HUANG, Chong TAO, Daniel Robert Johnson, Aniruddha S. WELING, Anthony KOWAL, Lei SUI

Patent number: 6731853Abstract: An optical fiber clamp that precisely aligns and clamps multiple optical fibers in multi-channel freespace optical systems, eliminates multiple parts and simplifies assembly. Multiple wafers each having an array of holes passing therethrough, are aligned with respect to each other. Optical fibers are passed through the holes, and at least one of the wafers is moved laterally with respect to the other wafers, so that sidewalls of the holes clamp the optical fibers into a desired location.Type: GrantFiled: August 14, 2001Date of Patent: May 4, 2004Assignee: Corning IncorporartedInventors: Robert A. Boudreau, Chris P. Brophy, Lawrence Charles Hughes, Jr., Mark F. Krol, Deepukumar M. Nair, Songsheng Tan, Aniruddha S. Weling
