Patent number: 11488617Abstract: Disclosed are a sound processing apparatus and a sound processing method. The sound processing method includes extracting a desired voice enhanced signal by a sound source separation and a sound extraction. By using a multi-channel blind source separation method based on independent vector analysis, the desired voice enhanced signal is extracted from a channel having the smallest sum of off-diagonal values of a separation adaptive filter when the power of the desired voice signal is larger than that of other voice signals. According to the present disclosure, a user may build a robust artificial intelligence (AI) speech recognition system by using sound source separation and voice extraction using eMBB, URLLC, and mMTC techniques of 5G mobile communication.Type: GrantFiled: October 18, 2019Date of Patent: November 1, 2022Assignee: LG ELECTRONICS INC.Inventors: Jae Pil Seo, Keun Sang Lee, Jae Woong Jeong

Patent number: 8925578Abstract: An aperture-shaped variable valve which is used for a semi-active control. The variable valve includes a ring-shaped aperture frame, a plurality of aperture plates which is arranged in a ring shape by overlapping each other on the aperture frame and forms an aperture, a restoring ring which fits into the outside of an aperture surface, and a spring which is connected between the restoring ring and the aperture frame.Type: GrantFiled: August 27, 2009Date of Patent: January 6, 2015Inventor: Keun Sang Lee

Publication number: 20110303864Abstract: The present invention relates to an aperture-shaped variable valve which is attached to the inside or end of a pipe to variably control the flow rate or pressure of fluid, such as liquid or gas, flowing along the pipe. As to one usage of the invention, the exhaust noise of an automobile can be controlled because back pressure is variably controlled by the valve attached to a vehicular exhaust system where the flow rate of exhaust gas varies according to the RPM of an engine. Additionally, the flow rate can be measured within a large range through application of the valve to a flowmeter. An operational principle of the valve is to control the cross section of the flow path by contract or release of aperture plates which are initially opened at a constant size by elasticity of a spring. Using the aperture-shaped variable valve, linear control of flow rate or pressure is facilitated, compared with a conventional disc variable valve.Type: ApplicationFiled: August 27, 2009Publication date: December 15, 2011Inventor: Keun Sang Lee
