Publication number: 20240046418Abstract: Systems, apparatuses, and methods for implementing defogging techniques for images and video are disclosed. A defogging engine generates a defog filter result from a grayscale format version of an input image. An estimation engine generates an enhancement strength variable from a hue-saturation-value (HSV) format version of the input image. An enhancement engine receives both the defog filter result from the defogging engine and the enhancement strength variable from the estimation engine. The enhancement engine also receives the original red-green-blue (RGB) color space format version of the input image. The enhancement engine generates an enhanced version of the input image from the original RGB format version based on the defog filter result and the enhancement strength variable. The enhanced version of the input image mitigates fog, haze, mist or other environmental impediments that obscured the original input image.Type: ApplicationFiled: August 2, 2022Publication date: February 8, 2024Inventor: Xiaodong Liang

Patent number: 10132853Abstract: The embodiments herein are directed to monitoring in real time, power system data so as to provide insights into global operation of a power grid. Such a scheme disclosed herein utilizes rules, which are created by analyzing PMU measurement data, in order to detect the fault location (bus and line) and fault type. Three common types of faults in a power grid, single-line-to-ground (SLG), line-to-line (LL), and three phase faults, can be detected using the methods herein.Type: GrantFiled: April 11, 2016Date of Patent: November 20, 2018Assignee: WASHINGTON STATE UNIVERSITYInventors: Xiaodong Liang, Scott Andrew Wallace, Xinghui Zhao

Patent number: 9503042Abstract: A subsea power distribution system includes a three-phase AC power source; multiple variable frequency drives having inputs and outputs, with their inputs connected to the AC power source; an electric motor connected in series to the output of each variable frequency drive; and a passive harmonic filter system having its input connected, in parallel with the variable frequency drives, to the AC power source. The filter system includes multiple harmonic filters, each harmonic filter tuned to a specific harmonic frequency. Each harmonic filter includes a plurality of sub-filters. Each sub-filter includes a reactor connected in series to a main capacitor and one or more detuning capacitors. Each of the multiple harmonic filters is tuned to a different specific harmonic, and includes sub-filters also tuned to the same respective harmonic, and each sub-filter is sized to equally share the kVAR load of its respective harmonic filter.Type: GrantFiled: February 24, 2015Date of Patent: November 22, 2016Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Xiaodong Liang, Obinna Chike Ilochonwu
