Publication number: 20230142822Abstract: A method and apparatus measures flicker while improving the computational performance for measuring flicker severity level. Specifically, an Intelligent Electronic Device employs a method in which a processor summarizes and characterizes a plurality of instantaneous flicker sensation level values as histogram formatted data and selects a specific percentile of the instantaneous flicker sensation level values from the histogram formatted data. The method employed by the device uses the specific percentile to calculate a short-term flicker severity level value.Type: ApplicationFiled: November 11, 2021Publication date: May 11, 2023Inventors: Ketao Li, Guanghao Yu, Junhui Wang, Haoliang Deng, Linxuan Chen, Xiao Wu, Kehao Si, Wenbing Tan, Yan Ding, Changcheng Hao, Alex Yeh, Liang Wang, Liwei Wang, Tao Xu, Shiheng Deng, Shaohang Cui, Youwei Zhang, Yufan Wang, Zihao Chen

Publication number: 20120016622Abstract: The present invention relates to the field of measurement technology, and offers a method for calculating an inner wall temperature from a measurement result of an outer wall temperature of a tube in relation to a problem of a two-dimensional, unsteady heat flow in tube. The evaluation method includes the steps of measuring outer wall temperatures at a plurality of points under a two-dimensional unsteady flow in the tube; and estimating inner wall temperatures on the basis of the measured values of the outer-wall temperatures. The approach of the present invention makes it possible to correctly estimate change over time of the inner wall temperature of the tube from the outer wall temperature of the tube with high accuracy, and requires a relatively short calculation time. For these reasons, the present invention is applicable to the problem in that the inner wall temperature of a tube is difficult to measure, in relation to flow in the tube in the industrial production and the scientific research.Type: ApplicationFiled: September 29, 2009Publication date: January 19, 2012Applicants: TSINGHUA UNIVERSITY, MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Peixue Jiang, Youwei Zhang, Hui Li
