Patent number: 11955888Abstract: As inputs of a controller of a direct current (DC)-DC converter are sampled for a predetermined time and thus two-dimensional state information in which one axis is an input physical quantity and the other axis is a time is generated, the two-dimensional state information is processed by a convolutional neural network to determine and output one of a plurality of control signals. An artificial intelligence control part may operate in accordance with a plurality of operation conditions or dynamically determined operation conditions by applying different artificial intelligence engines according to operation modes.Type: GrantFiled: July 3, 2021Date of Patent: April 9, 2024Inventors: Kang Yoon Lee, Jong Wan Jo, Min Young Kim, Dong Soo Park, Kyung Duk Choi, Young Gun Pu

Publication number: 20240107002Abstract: A method for coding image information includes generating prediction information by predicting information on a current coding unit, and determining whether the information on the current coding unit is the same as the prediction information. When the information on the current coding unit is the same as the prediction information, a flag indicating that the information on the current coding unit is the same as the prediction information is coded and transmitted. When the information on the current coding unit is not the same as the prediction information, a flag indicating that the information on the current coding unit is not the same as the prediction information and the information on the current coding unit are coded and transmitted.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Applicants: Electronics and Telecommunications Research Institute, University-Industry Cooperation Group of Kyung Hee UniversityInventors: Se Yoon JEONG, Hui Yong KIM, Sung Chang LIM, Jin Ho LEE, Ha Hyun LEE, Jong Ho KIM, Jin Soo CHOI, Jin Woong KIM, Chie Teuk AHN, Gwang Hoon PARK, Kyung Yong KIM, Tae Ryong KIM, Han Soo LEE

Publication number: 20240073416Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.Type: ApplicationFiled: November 6, 2023Publication date: February 29, 2024Applicants: Electronics and Telecommunications Research Institute, Kwangwoon University Industry-Academic Collaboration Foundation, Universily-lndustry Cooperation Group of Kyung Hee UniversityInventors: Sung Chang LIM, Ha Hyun LEE, Se Yoon JEONG, Hui Yong KIM, Suk Hee CHO, Jong Ho KIM, Jin Ho LEE, Jin Soo CHOI, Jin Woong KIM, Chie Teuk AHN, Dong Gyu SIM, Seoung Jun OH, Gwang Hoon PARK, Sea Nae PARK, Chan Woong JEON

Patent number: 9261088Abstract: A linear compressor can prevent leakage of a magnetic force by changing the construction of a linear motor. As the construction of the linear motor is changed, a mechanical spring constant is set smaller in consideration of a magnetic spring constant, so that the size of springs supporting a piston in the reciprocal linear motion direction can be reduced and components supporting the springs can be removed. Therefore, the linear compressor achieves a small size/a light weight. With the characteristics of the linear motor construction, the linear compressor can suppress a stroke spreading influence and easily expand a compression capacity according to a load.Type: GrantFiled: August 5, 2010Date of Patent: February 16, 2016Assignee: LG ELECTRONICS INC.Inventors: Ki Wook Song, Jong Yoon Choi, Cheal Lak Choi

Patent number: 8277204Abstract: A reciprocating motor and a reciprocating compressor having the same are provided. One side of each of outer and inner cores forming a stator are connected to each other, to prevent a magnetic flux generated by the coil and a magnet from leaking out of the stator. Hence, it is possible to fabricate components of the reciprocating compressor employing such a reciprocating motor by using a relatively low-cost magnetic substance, resulting in a decrease in fabricating costs of the compressor. Also, a length of the magnet may be reduced, which results in a reduction of the cost for the magnet, thereby decreasing fabricating costs of the reciprocating motor and the reciprocating compressor employing the reciprocating motor.Type: GrantFiled: April 1, 2009Date of Patent: October 2, 2012Assignee: LG Electronics Inc.Inventors: Jong-Yoon Choi, Kyeong-Bae Park, Ki-Chul Choi, Eon-Pyo Hong, Jin-Sung Park

Patent number: 7766036Abstract: A discharge valve (100) of a compressor is disclosed. The discharge valve (100) contains a spring-loaded valve body (120). Valve body (120) is preferably made of nonferrous metal like aluminum or magnesium and is coated by a covering (110) of uniform thickness, the covering (110) being preferably made of plastic material like polyetheretherketone (PEEK) by insertion molding. By that way a wear resistant and light-weight discharge valve is produced.Type: GrantFiled: November 11, 2005Date of Patent: August 3, 2010Assignee: LG Electronics Inc.Inventors: Jong-Yoon Choi, Sang-Wook Ahn, Bon-Cheol Ku, Hyung-Pyo Yoon, Hyo-Jae Lee, Seong-Yeol Hyeon
