Patent number: 9828572Abstract: A method is provided for removing a volatile organic compound (VOC) contained in an artificial leather fabric and odor caused by the volatile organic compound by coating the artificial leather fabric with an adsorbent which reacts with a noxious substance containing the volatile organic compound (VOC); and immersing; washing; and drying the reacted artificial leather fabric. The method includes coating the adsorbent and immobilizing the volatile organic compound through a reaction, to prevent volatilization of the organic compound or reduce an amount thereof. Further, after the reaction between the artificial leather fabric and the adsorbent, the artificial leather fabric is washed, to remove the volatile organic compound immobilized on a surface of the fabric from the artificial leather.Type: GrantFiled: September 3, 2014Date of Patent: November 28, 2017Assignee: Hyundai Motor Company Kolonglotech, Inc.Inventors: Gun Kang, Hyun Joo Seo, Mi Jung Yun, Dae Seok Choi, Yong Tae Ha, Min Jeong Kim, Ju Ahn Kim, Ki Eop Kim, Yoon Jung Kwon, Shin Hyouk Kang

Patent number: 7978625Abstract: An apparatus and a method for selectively retransmitting data according to a channel state in a wireless communication system are provided. The method includes determining retransmission information of a receiver from feedback information received from the receiver, determining a retransmission scheme for the receiver using the retransmission information of the receiver, and performing a retransmission process with the receiver according to the determined retransmission scheme. In a good channel state, the data is retransmitted using the retransmission scheme to thereby enhance the reliability of the data delivery and the reception performance. In a bad channel state, the data is not retransmitted to thereby reduce a waste of resources in the data retransmission.Type: GrantFiled: July 14, 2008Date of Patent: July 12, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Hyeong-Jong Ju, Hee-Kwun Cho, Dae-Seok Choi

Publication number: 20070127499Abstract: A voice packet communication apparatus and method in a wireless communication system are provided. The communication method includes extracting, at a base station, RTP data from an IP packet received from a corresponding terminal in voice packet communication, generating the RTP data as a MAC PDU, and sending the generated MAC PDU to a wireless terminal; and extracting, at the wireless terminal, the RTP data from the MAC PDU received from the base station and reproducing the RTP data through a voice codec. Since the amount of data to be transmitted and received in the radio section is reduced, the present invention can enhance the bandwidth efficiency.Type: ApplicationFiled: December 5, 2006Publication date: June 7, 2007Applicant: SAMSUNG ELECTRONICS CO., LTDInventors: Dae-Seok Choi, Young-Jun Park, Kug Shin
