Patent number: 11880695Abstract: This application provides a plug-in implementation system and method. The system includes a plug-in module and a terminal software module. When the terminal software module does not include a service implementation of a first plug-in interface, the plug-in module may load a default implementation of the first plug-in interface to invoke the first plug-in interface. In this way, a plug-in may be extended to extend a service function of a terminal. In addition, when the plug-in interface is inconsistent with a plug-in function, the default implementation of the plug-in interface is implemented by using the plug-in module, so that an open-source software module can run normally, to ensure normal running of an electronic device as much as possible. Therefore, the open-source software module no longer depends on the terminal software module, and the terminal software module can be decoupled from the open-source software module.Type: GrantFiled: March 17, 2022Date of Patent: January 23, 2024Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Zhenchao Lin, Chao Ding, Linlin Tu, Jinfei Wang, Xiaoxuan Chen, Weisai Ning, Zhongling Chen, Lei Liu, Qinhua Jiang

Patent number: 9017454Abstract: A method for removing SOx (x=2 and/or 3) from gas using a solution having polyethylene glycol as the main ingredient. First, SOx in the gas is absorbed by the solution of polyethylene glycol. Second, the solution of polyethylene glycol which has absorbed SOx is regenerated by one or more of the heating, vacuum, ultrasonic, microwave or radiation methods, thereby releasing the by-products of sulfur dioxide and sulfur trioxide. The regenerated solution of polyethylene glycol is recycled. When the water content of the regenerated solution of polyethylene glycol is high enough to affect the desulfurization, it needs to be removed. Removal methods include heating and rectification, absorption using a water absorbent, or a combination of these methods. The polyethylene glycol solution is recycled after dehydration.Type: GrantFiled: February 10, 2010Date of Patent: April 28, 2015Assignees: Beijing Boyuan-Hengsheng High-Technology Co., Ltd., Yongfeng Boyuan Industry Co.
