Publication number: 20240077417Abstract: The disclosure relates to a non-dispersive infrared (NDIR) gas sensor which detects the concentration of gas with a simple structure and method by manufacturing an optical waveguide with a gas-permeable polymer material instead of a conventional cavity or chamber type. An optical signal travels through the optical waveguide of gas-permeable polymer by total internal reflection, and the gas naturally penetrates the optical waveguide without the use of separate inlet and outlet openings, so that the optical signal and gas particles come into contact with each other within the optical waveguide. Since the optical signal detected by a photodetector at the other end of the optical waveguide after traveling while contacting the gas particles has properties changed according to the concentration of the gas which they have contacted in the optical waveguide, it is possible to measure the concentration of a specific gas from the detected optical signal.Type: ApplicationFiled: July 11, 2023Publication date: March 7, 2024Applicant: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Jin Hwa RYU, Soocheol KIM, Hyunseok KIM, So Yung PARK, Hoe-Sung YANG, Kang Bok LEE, Kwang-Soo CHO, Kyu Won HAN

Patent number: 7269423Abstract: A QoS-based call admission system and method for a mobile communication system. To establish a call for a mobile station according to the QoS of the call, upon request of setup of a call requiring a QoS guarantee, a base transceiver station determines whether a channel element is available. In the presence of an available channel element, the base transceiver station determines whether a remaining bandwidth can support a data rate required to guarantee the QoS. If the data rate is supported, the base transceiver station assigns the channel element and connects its intra switch to a base station controller. Then the base transceiver station transmits a call accept response signal to the base station controller.Type: GrantFiled: January 9, 2003Date of Patent: September 11, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Sung-Won Lee, Young-Ky Kim, Dong-Soo Park, Dong-Jun Lee, Sang-Soo Kim, Jin-Sung Cho

Patent number: 7065362Abstract: A base station controller (BSC) performs a handoff of a mobile terminal (MT) moving between cells of base transceiver stations (BTSs) in a mobile communication system. If a target BTS is selected as a handoff candidate for the MT as the MT moves from a cell of a source BTS in service toward a cell of the target BTS, the BSC transmits to the target BTS a first message for requesting the target BTS to buffer packets, and transmits packets to be transmitted to the MT to both the source BTS and the target BTS. If the target BTS is determined as a serving BTS for the MT, the BSC transmits to the target BTS a second message including a last sequence number in order to request the target BTS to transmit, to the MT, packets with sequence numbers following the last sequence number of a last packet transmitted from the source BTS to the MT, among the buffered packets.Type: GrantFiled: December 12, 2002Date of Patent: June 20, 2006Assignee: Samsung Electronics Co., Ltd.Inventors: Sung-Won Lee, Young-Ky Kim, Dong-Soo Park, Dong-Jun Lee, Sang-Soo Kim, Jin-Sung Cho

Publication number: 20030139145Abstract: A data transmitting method and apparatus with QoS guaranteed in a communication system supporting services with different QoS requirements. The services are classified into a QoS service and a non-QoS service and discriminately processed according to the classification. To maximize the efficiency of transmission links, the data rate of a service is dynamically controlled according to the state of the transmission links. Furthermore, the transmission links are prioritized to guarantee the quality of the QoS service even when data congestion occurs and data burstness is regulated to minimize a congestion period during data transmission. Therefore, QoS guarantee is maximized according to services in a communication system supporting data service.Type: ApplicationFiled: November 27, 2002Publication date: July 24, 2003Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Sung-Won Lee, Young-Ky Kim, Dong-Soo Park, Dong-Jun Lee, Sang-Soo Kim, Jin-Sung Cho
