Patent number: 11962968Abstract: Embodiments of this application disclose a noise cancellation apparatus and method. The noise cancellation apparatus includes a main control unit and a noise cancellation processing circuit. The main control unit determines a noise cancellation parameter based on a noise cancellation level index or a feature value for determining a matching degree between a headset and an ear canal of a user. The noise cancellation processing unit obtains an inverse phase noise of an ambient noise based on the noise cancellation parameter. After the inverse phase noise is mixed with a played downlink audio signal, the ambient noise can be canceled. In addition, because the noise cancellation parameter is determined from a preset noise cancellation parameter library based on the received or autonomously determined noise cancellation level index, instead of being uniformly configured, a noise cancellation level can be flexibly adjusted, thereby improving a noise cancellation effect and user experience.Type: GrantFiled: October 7, 2021Date of Patent: April 16, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Jiang Li, Yulong Li, Xiaowei Yu, Fan Fan, Xiaohong Yang, Yangshan Ou, Jingfan Qin

Patent number: 10323247Abstract: The invention discloses a method for improving the extracellular expression level of a foreign protein by means of phospholipase fusion expression. Four proteins, PLA2, MBP, CBD and SUMO, are used as a fusion tag to construct a fusion gene. Compared with an original protein MOH without any fusion tag, the extracellular expression level and enzymatic activity of all the four fusion proteins are increased to some degree. Among them, the fusion protein using PLA2 as the fusion tag has the highest expression level, which is 7.4 times higher than that of the original protein. Compared with other fusion tags, PLA2 has a low molecular weight and the fusion protein having PLA2 as the fusion tag has the highest expression level (up to 12 g·L?1 in a 7 L fermentation tank for high-density fermentation). It is shown that the secretory expression of a foreign protein can be effectively increased by using PLA2 as a fusion tag.Type: GrantFiled: June 1, 2018Date of Patent: June 18, 2019Assignee: Jiangnan UniversityInventors: Xiaowei Yu, Yan Xu
