Patent number: 11991500Abstract: A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.Type: GrantFiled: April 23, 2023Date of Patent: May 21, 2024Assignee: SHENZHEN SHOKZ CO., LTD.Inventors: Xin Qi, Fengyun Liao, Jinbo Zheng, Qian Chen, Hao Chen

Patent number: 11371344Abstract: A method for identifying a medium structure coupling and a fracture network morphology of a shale gas reservoir includes the following steps. Firstly, performing a fracturing test on shale cores by using a modified Brazilian disc test and categorizing the fracture network morphology. Secondly, performing a shale matrix-fracture structure and stress sensitivity test on the shale cores having different fracture network morphology. After that, determining a stress sensitivity constant of different fracture network morphology according to indoor core data and finally preparing an identification chart of the fracture network morphology based on an indoor core stress sensitivity test combined with a production practice. The identification chart can be applied to an actual fracturing well, and the fracture network morphology is directly identified by a real-time effective stress and a normalized flow.Type: GrantFiled: September 21, 2018Date of Patent: June 28, 2022Assignee: UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Weiyao Zhu, Zhiyong Song, Ming Yue, Yunfeng Liu, Zhen Chen, Dongxu Ma, Wenchao Liu, Qian Qi

Patent number: 8106898Abstract: A system for compensating for skew in a color video signal transmitted by a cable having multiple conductors is described. A test pulse signal (e.g. a 2 MHz signal) is inserted into the color components (e.g. RGB) of the video signal during time periods in each frame when the RGB video signals are inactive, such as within 300 ?s after the V sync signal. After transmission over the cable, the RGB components with the inserted test signal are delayed relative to each other using a delay line in cooperation with a control circuit. The delay line generates detect signals by detecting relative delays of the test signal pulses inserted in the RGB components. The control circuit controls the amount of delay in the delay line based on the detect signals, so that the RGB components in the video signal outputted by the delay line are synchronized.Type: GrantFiled: March 23, 2009Date of Patent: January 31, 2012Assignee: Aten International Co., Ltd.Inventors: Yun-Song Gou, Hong-Tao Wen, Qian-Qi Zhuang

Publication number: 20110057881Abstract: Disclosed is a KVM management system and method of providing synchronization signal adaptable depending one user's demand. The KVM management system includes a first module and a second module. The first module converts a first type of synchronization signal selected from a first group of synchronization signal combinations into a transitional signal. The second module converts the transitional signal into a second type of synchronization signal selected from a second group of synchronization signal combinations for the display. The transitional signal may be a composite synchronization signal combines one of red, green, blue video signals from the computer and carried on at least one pair of wire in an Ethernet network cable. The type of transitional signal can be predetermined by adjusting a first register stored in the first module. The second type of synchronization signal can be predetermined by adjusting a second register stored in the second module.Type: ApplicationFiled: September 4, 2009Publication date: March 10, 2011Applicant: ATEN INTERNATIONAL CO., LTD.Inventors: HONG-TAO WEN, YUN-SONG GOU, QIAN-QI ZHUANG
