Publication number: 20240073554Abstract: The present application provides a system and a method for acquiring an image, an electronic device, and a computer-readable storage medium. The system for acquiring an image provided in the present application provides a correction reference with uniform illumination by adjusting the positional relationship between the light source and the correction reference, and acquires at least one image of the correction reference by the image acquisition device to be corrected. Wherein, the correction image obtained based on the at least one image may be used to perform lens shading correction on the image acquisition device. The system for acquiring an image does not require the use of an expensive integrating sphere, which may reduce purchase and maintenance costs of a testing device for obtaining a correction image.Type: ApplicationFiled: August 24, 2023Publication date: February 29, 2024Applicant: Black Sesame Technologies (Shenzhen) Co., Ltd.Inventors: Anzhou Hu, Louise Law, Chao Wang, Donghui Wu

Patent number: 10634034Abstract: A common rail comprises a shell and a pressure detection apparatus and a pressure adjustment apparatus that are installed on the shell. The shell comprises an inlet passage, an outlet passage, at least one conveyance port that is connected to the inlet passage, and at least one flow return port that is connected to the outlet passage. The pressure detection apparatus is connected to the inlet passage. The pressure adjustment apparatus is connected between the inlet passage and the outlet passage. The pressure adjustment apparatus can connect or disconnect the inlet passage and the outlet passage. Also disclosed is a carbamide spraying system having such a common rail. Because a carbamide solution returned from a nozzle is first gathered inside the common rail and then returns to a carbamide tank through the outlet passage and a return flow pipe, the length of the return flow pipe is reduced.Type: GrantFiled: November 12, 2015Date of Patent: April 28, 2020Assignee: TENNECO (SUZHOU) EMISSION SYSTEM CO., LTD.Inventors: Gaofeng Fan, Zhenqiu Yang, Haitao Zhang, Anzhou Wu, Shuai Guan

Patent number: 10202883Abstract: A common rail assembly used in a urea injection system, comprising at least a first common rail and a second common rail which are connected to each other, wherein the first common rail comprises a first housing, a pressure detecting device mounted on the first housing and a pressure adjusting device. The first housing comprises a first urea inlet channel, a first urea outlet channel, at least one first feeding inlet connected to the first urea inlet channel and at least one first back-flow outlet connected to the first urea outlet channel. The pressure detecting device is connected to the first urea inlet channel. The pressure adjusting device can connect/disconnect the first urea inlet channel to/from the first urea outlet channel. Also disclosed are a urea injection system and the application of the common rail assembly.Type: GrantFiled: November 12, 2015Date of Patent: February 12, 2019Assignee: TENNECO (SUZHOU) EMISSION SYSTEM CO., LTD.Inventors: Zhenqiu Yang, Chao Gong, Gaofeng Fan, Daling Liu, Haitao Zhang, Anzhou Wu, Shuai Guan

Patent number: 9719386Abstract: An exhaust after-treatment system including at least one exhaust treatment component (18); and a particulate matter dispersion device (40) located upstream of the exhaust treatment component (18). The particulate matter dispersion device (40) includes at least one nozzle line (61) having a plurality of nozzles (58) formed therein, and the particulate matter dispersion device (40) is operable to inject compressed gas towards the exhaust treatment component (18) to substantially minimize build-up of particulate matter at the exhaust treatment component (18).Type: GrantFiled: January 31, 2013Date of Patent: August 1, 2017Assignee: Tenneco Automotive Operating Company Inc.Inventors: Gaofeng Fan, Biao Du, Lin Wang, Jianqiang Fan, Anzhou Wu, Jian Wu, Michael Golin

Patent number: 9334775Abstract: An exhaust treatment system may include gas, reductant and water conduits, a nozzle and a pump. The gas conduit may be in fluid communication with a source of compressed gas and may include a first valve controlling a flow of compressed gas through the gas conduit. The water conduit may be in fluid communication with a water source and may include a second valve controlling a flow of water through the water conduit. The nozzle may be in fluid communication with the gas, reductant and water conduits. The pump may be disposed between the nozzle and the second valve and may be in fluid communication with the reductant and water conduits. The pump may be operable in a first pumping direction to pump reductant from the reductant source to the nozzle and in a second pumping direction to pump reductant away from the nozzle and toward the reductant source.Type: GrantFiled: August 16, 2013Date of Patent: May 10, 2016Assignee: Tenneco Automotive Operating Company Inc.Inventors: Anzhou Wu, Joshua Hicks, Padmanabha Reddy Ettireddy, Daniel R. Johnson, Ryan A. Floyd, Gaofeng Fan
