Publication number: 20100074217Abstract: Disclosed is a method for operating sectors of a base station in a mobile telecommunication system. For this, the method includes the steps of: outputting, at a prescribed time period equal to T1, data, including alpha sector data, beta sector data, and gamma sector data, which is to be transmitted to a mobile station, in sequence and by sectors; dividing a frequency in a scheme of time division at a time period which equals either t?, t? or t? and which corresponds to the data length by the sector of data which is output in the outputting data, and carrying out a frequency assignment in sequence and by the sector. Accordingly, only relevant data is transmitted to a sector assigned the frequency, and a traffic variation of each sector can be met.Type: ApplicationFiled: December 4, 2006Publication date: March 25, 2010Applicant: KMW INC.Inventors: Duk-Yong Kim, Jung-Pil Lee, Young-Chan Moon, Jin-Chul Hwang

Patent number: 6955240Abstract: A dual-stage air bag module for a passenger seat capable of easily controlling and changing gas pressures to be provided into an air cushion, and also implementing a miniaturization and a lightweight of the air bag module. The first and second inflators, which are controlled by a control unit, are arranged in a diagonal direction to each other within a housing. The first and second inflators are generally inflators for a driver seat air bag modules mounted in a steering wheel. The retainer is fixed in the state that a portion thereof is received in the upper portion of the housing in order to fix the cushion holder assembled with the air cushion within the housing. The retainer is coupled through a predetermined coupling member to the housing with the first and second inflators.Type: GrantFiled: December 23, 2002Date of Patent: October 18, 2005Assignee: Hyundai Mobis Co., Ltd.Inventors: Jung-Bae Ahn, Jin-Chul Hwang, Seo-Hong Kim, Ju-Hyung Seo, Tae-Ho Song

Patent number: 6918610Abstract: A membrane horn switch structure of an airbag module does not include a back plate, which simplifies an inner configuration of a bag cover and ensures stable operation. The structure includes an outer support plate installed on a plurality of protrusions formed at an inner bottom of the bag cover, the outer support plate including a pair of films having edges which are sealed to form an inner space. A membrane horn switch unit includes a pair of inner support plates having an arc shape, which are installed in the outer support plate. The inner support plates are overlapped and spaced apart from each other. One end of each inner support plate is fixed to the outer support plates, and the other end of each inner support plate is free, so that the inner support plates are in contact with each other when the outer support plate is pressed.Type: GrantFiled: January 6, 2003Date of Patent: July 19, 2005Assignee: Hyundai Mobis Co., Ltd.Inventors: Tae-ho Song, Byung-ryong Cho, Jin-chul Hwang, Seo-hong Kim, Jung-bae Ahn, Ju-hyung Seo
