Patent number: 11920594Abstract: A screw compressor slide valve with gas pulsation attenuation function includes valve walls and internal through holes. A screw compressor includes the screw compressor slide valve. A part of exhausted gas of the screw compressor is directly discharged from an exhaust port to an exhaust chamber to form a main exhaust flow channel; another part of the exhausted gas is discharged from the exhaust port into the exhaust chamber after being delayed by the internal through holes, which forms a branched exhaust flow channel. Since the branched exhaust flow channel is longer than the main exhaust flow channel, when the gas pulsation in the branched exhaust flow channel lags behind that in the main exhaust flow channel by 180-degree in phase, two gas pulsations in the two flow channels are offset due to opposite gas pulsation phases, which attenuates the gas pulsation, thereby suppressing induced vibration and noise.Type: GrantFiled: December 26, 2018Date of Patent: March 5, 2024Assignee: XI'AN JIAOTONG UNIVERSITYInventors: Ziwen Xing, Minglong Zhou, Wenqing Chen, Chuang Wang, Zhilong He

Patent number: 10491380Abstract: A method for updating firmware on a control module of a modular assembly system is provided. Information related to noise sampled from the control module is obtained. A first encryption key is calculated based on the information. Firmware to be updated on the control module is received from a host of the modular assembly system. The firmware is encrypted based on at least a second encryption key. In response to determining that the received firmware can be decrypted, the decrypted firmware is loaded into the control module. At least one of the obtaining, calculating, receiving, determining, and loading is performed by the control module.Type: GrantFiled: May 22, 2017Date of Patent: November 26, 2019Assignee: SHENZHEN BELL CREATIVE SCIENCE AND EDUCATION CO., LTD.Inventors: Zuobing Wang, Hongbo Qi, Jinfu Zhou, Ziwen Chen
