Publication number: 20240133642Abstract: The present invention relates to an integrated connector and a heat exchanger including the same, in which a connector main body is formed by pressing one pipe, a cap is press-fitted into the connector main body, such that the integrated connector is formed so that an interior of the connector main body is blocked by the cap. Therefore, the number of components used to manufacture a connector, which connects and securely couples a header tank and a gas-liquid separator, may be reduced, the integrated connector may be easily manufactured, and a brazing defect may be reduced at portions where the integrated connector is joined to the header tank and the gas-liquid separator of the heat exchanger.Type: ApplicationFiled: September 26, 2023Publication date: April 25, 2024Inventors: Seung Hark SHIN, Woon Sik KIM, Dae Sung NOH, Hyunwoo CHO, Min Won SEO, Sung Hong SHIN, Jong Du LEE, Jung Hyun CHO, Uk HUH

Patent number: 11566131Abstract: Disclosed are a composite resin composition and an article containing the same. The composite resin composition may include semicrystalline polyamide; amorphous polyamide; an acrylonitrile-butadiene-styrene (ABS) resin; a compatibilizer; and a strength-reinforcing agent. The article may exhibit superior rigidity equivalent to or greater than that of conventional long-fiber thermoplastics and remarkably excellent dimensional stability. In addition, the composite resin composition and the molded article including the same may be used in replacement of steel parts so as to reduce the weight by about 30%.Type: GrantFiled: November 24, 2020Date of Patent: January 31, 2023Assignees: Hyundai Motor Company, Kia Motors Corporation, Hyundai Advanced Materials Co., Ltd.Inventors: Sang Sun Park, Han Sol Lee, Kyeong Bae Seo, Min Sik Seo, In Seok Kang, Wan Ki Noh, Jae Han Park, Dong Hyun Kim, Hea Lin Kim, Hyung Joo Lee, Seung Soo Hong, Dong Chang Lee, Hyeung Min Lee

Patent number: 8654876Abstract: Provided are a transmitting apparatus and a transmitting method in a multiple input multiple output system. A power allocation controller includes a block Tomlinson-Harashima precoder (BTHP) that precodes and outputs data to be transmitted to each user in a nonlinear scheme. The BTHP removes and outputs inference signals from data for each user based on the channel information that is fed back from the users. The data for each user output from the BTHP are allocated with power by the power allocation controller. The power allocation controller calculates power allocation parameters so that receiving minimum distances at receiving ends for each user that receive data through the MIMO antennas are the same, and allocates the calculated parameters to data for each user.Type: GrantFiled: November 24, 2009Date of Patent: February 18, 2014Assignees: Samsung Electronics Co., Ltd., Electronics and Telecommunications Research InstituteInventors: Young Seog Song, Choongil Yeh, Dong Seung Kwon, Min Sik Seo, Joondoo Kim, Jiwon Kang, Chungyong Lee

Patent number: 8625688Abstract: A method for a transmitting terminal in a multi-user multi-antenna environment to perform precoding includes: receiving feedback information from a plurality of receiving terminals; estimating a channel between the transmitting terminal and the plurality of receiving terminals by using the feedback information; and generating a plurality of transmission symbols by applying a first nonlinear precoding method and a second nonlinear precoding method to a plurality of symbols and the estimated channel to be transmitted to the plurality of receiving terminals. The first nonlinear precoding method is used to eliminate interference between subchannels of the same receiving terminal, and the second nonlinear precoding method is used to eliminate interference between the receiving terminals.Type: GrantFiled: November 24, 2009Date of Patent: January 7, 2014Assignees: Samsung Electronics Co., Ltd., Electronics and Telecommunications Research InstituteInventors: Choongil Yeh, Young Seog Song, Min Sik Seo, Dong Seung Kwon, Joon-doo Kim, Chungyong Lee, Jiwon Kang
