Patent number: 9873084Abstract: A reducing agent pyrolysis system for a selective catalytic reduction apparatus includes an elbow duct that is installed on an exhaust duct at a front end of a reactor, allows exhaust gas to flow into the elbow duct, and allows the inflow exhaust gas to be discharged toward the reactor. An inner pipe unit is disposed in the elbow duct, and allows a part of the exhaust gas to flow into and be discharged from the inner pipe unit. A heating device is installed in the inner pipe unit, and heats the exhaust gas flowing into the inner pipe unit. A nozzle is installed in the inner pipe unit, is disposed at a rear end of the heating device based on a flow of the exhaust gas, and injects a reducing agent into the inner pipe unit.Type: GrantFiled: December 6, 2013Date of Patent: January 23, 2018Assignee: Doosan Engine Co., Ltd.Inventors: Jae Moon Lee, Sang Jin Kim, Jong Tae Choi, Chang Hee Lee

Patent number: 8194127Abstract: The present invention makes a privacy protection area set on a video frame always match a masking block for the privacy protection area, thereby preventing video images taken from the privacy protection area from being exposed. One embodiment of the invention sets a masking zone corresponding to a privacy protection area on a taken video frame, keeps examining if the set masking zone does not match the privacy protection area, and adjusts the position of the masking zone on the video frame if it is determined that the masking zone does not match the privacy protection area, thereby preventing video signals taken from the initially set privacy protection area from being outputted.Type: GrantFiled: November 7, 2006Date of Patent: June 5, 2012Assignee: LG Electronics Inc.Inventors: Kyun Ho Kang, Sung Ha Seo, Byung Jin Park, Jong Tae Choi

Patent number: 7817190Abstract: An imaging processing device and method where, when areas having a luminance difference set by a user, for example, 45 dB or more, are preset in an image captured by a camera, an area, the luminance level of which exceeds a predetermined threshold level, may be displayed as a gray level or a black level, with the luminance thereof decreased by a certain luminance level, or may be displayed while a mask, having a gray or black level, and the area, the luminance level of which exceeds the predetermined threshold level, overlap each other. Therefore, glare caused by a high luminance subject can be decreased, or other subjects present in a backlit image can be easily recognized.Type: GrantFiled: July 23, 2007Date of Patent: October 19, 2010Assignee: LG Electronics Inc.Inventors: Sung Ha Seo, Kyun Ho Kang, Jong Tae Choi, Byung Jin Park
