Publication number: 20240115158Abstract: A method for counting coughs is provided. The method includes acquiring a plurality of onset signals from the sound signal, wherein the onset signal has a predetermined time length; acquiring a plurality of spectrograms corresponding to each of the plurality of onset signals; determining whether each of the acquired plurality of spectrograms represents a cough using a cough determination model; and calculating a number of coughs included in the sound signal based on a time point of a cough signal. The cough signal is an onset signal corresponding to one spectrogram determined to represent the cough. When a time interval between a first time point of a first cough signal and a second time point of a second cough is within a reference time interval, the first cough signal and the second cough signal are regarded as one cough signal at the first time point.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Applicant: DAIN TECHNOLOGY, INC.Inventors: Jee Young SONG, Ji Young JUNG, Sang Youn KANG, Kyeong Yeon DOO, On Sub KIM, Ah Ra LEE

Publication number: 20140132700Abstract: In a Voice over Internet Protocol (VoIP) video communication method and apparatus, first and second VoIP-based terminals store video event indexes and images mapped thereto with respect to state information of a user and terminal, and establish a session using session establishment information defining the video event. The first terminal then transmits a data packet including the video event index, and the second terminal receives the data packet and outputs an image mapped to the video event index of the images stored in advance. Thus, by transmitting and receiving a predefined index alone without transmitting user and terminal states as a real time data-type image, the VoIP video communication method and apparatus prevent unnecessary waste of bandwidth in video communication.Type: ApplicationFiled: January 23, 2014Publication date: May 15, 2014Applicant: Samsung Electronics Co., Ltd.Inventors: Soung-Kwan KIMN, Hyun-Min YOON, Hui-Jae LEE, Ji-Youn JUNG, Myeon-Kee YOUN, Seong-Joon JEON
