Patent number: 11943447Abstract: Disclosed herein are a decoding method and apparatus and an encoding method and apparatus that perform inter-prediction using a motion vector predictor. For a candidate block in a col picture, a scaled motion vector is generated based on a motion vector of the candidate block. When the scaled motion vector indicates a target block, a motion vector predictor of the target block is generated based on the motion vector of the candidate block. The motion vector predictor is used to derive the motion vector of the target block in a specific inter-prediction mode such as a merge mode and an AMVP mode.Type: GrantFiled: July 13, 2022Date of Patent: March 26, 2024Assignees: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE, INDUSTRY-ACADEMIA COOPERATION GROUP OF SEJONG UNIVERSITY, INDUSTRY-UNIVERSITY COOPERATION FOUNDATION KOREA AEROSPACE UNIVERSITYInventors: Sung-Chang Lim, Jung-Won Kang, Hyunsuk Ko, Jin-Ho Lee, Ha-Hyun Lee, Dong-San Jun, Hui-Yong Kim, Yung-Lyul Lee, Nam-Uk Kim, Jae-Gon Kim

Publication number: 20210386327Abstract: A patient monitoring system to help manage a patient that is at risk of falling is disclosed. The system includes a patient-worn wireless sensor that can be affixed to the patient's back that senses the patient's motion and wirelessly transmits information indicative of the sensed motion to a patient monitor. The patient monitor receives, stores, and processes the transmitted information to determine whether the patient has fallen or is about to fall. Upon such detection, the system can notify the patient's caretakers that the patient has fallen or is about to fall and therefore, is in need of immediate attention.Type: ApplicationFiled: June 30, 2021Publication date: December 16, 2021Inventors: Sung Uk Lee, Ammar Al-Ali, Faisal Kashif, Mohammad Usman, Massi Joe E.

Publication number: 20210369231Abstract: A physiological acoustic monitoring system receives physiological data from an acoustic sensor, down-samples the data to generate raw audio of breathing sounds and compresses the raw audio. The acoustic monitoring system has an acoustic sensor signal responsive to tracheal sounds in a person. An A/D converter is responsive to the sensor signal so as to generate breathing sound data. A decimation filter and mixer down-samples the breathing sound data to raw audio data. A coder/compressor generates compressed audio data from the raw audio data. A decoder/decompressor decodes and decompresses the compressed audio data into decompressed audio data. The decompressed audio data is utilized to generate respiration-related parameters in real-time. The compressed audio data is stored and retrieved so as to generate respiration-related parameters in non-real-time. The real-time and non-real-time parameters are compared to verify matching results across multiple monitors.Type: ApplicationFiled: April 16, 2021Publication date: December 2, 2021Inventors: Ammar Al-Ali, Sung Uk Lee
