Patent number: 11870643Abstract: A reconfigurable triplexer that can support more frequency bands than a traditional triplexer is disclosed. For example, the reconfigurable triplexer can handle frequencies of several hundred megahertz up to 10 gigahertz. Further, certain implementations of the reconfigurable multiplexer can reduce or eliminate frequency dead zones that exist with traditional multiplexers. The reconfigurable triplexer includes a multi-stage filter bank capable of supporting a number of frequency bands and a bypass circuit that enables the triplexer to support a variety of sets of frequencies. For instance, unlike traditional triplexers, the reconfigurable triplexer can support both frequency bands with relatively narrow spacing and frequency bands with relatively wide spacing. Further, the inclusion of the bypass circuit enables the reduction or elimination of dead zones between supported frequencies.Type: GrantFiled: June 30, 2021Date of Patent: January 9, 2024Assignee: Skyworks Solutions, Inc.Inventors: Yang Hou, Reza Kasnavi, Jianxing Ni, Shanshan Zhao

Patent number: 10981816Abstract: The present invention belongs to the technical field of wastewater treatment, and particularly relates to a method for pre-conditioning high-calcium wastewater by calcification blocking, and a device for implementing the method. The method for treating high-calcium wastewater by calcification blocking includes mixing high-calcium wastewater, an alkalizing agent and a chelating agent, and carrying out alkalizing conditioning pretreatment under a condition of stirring by bubbling of a biogas, so as to obtain pre-conditioned wastewater. The pre-conditioned wastewater is mixed with anaerobic granular sludge, and an anaerobic reaction is performed in a high hydraulic shear flow field formed by the biogas, so as to generate the biogas and calcium scale. A part of the biogas for the stirring is refluxed by bubbling of the biogas and the rest of the biogas is refluxed for forming the high hydraulic shear flow field.Type: GrantFiled: May 28, 2020Date of Patent: April 20, 2021Assignee: GUANGXI UNIVERSITY COLLEGE OF LIGHT INDUSTRY AND FOOD ENGINEERINGInventors: Shuangfei Wang, Jian Zhang, Chengrong Qin, Peng Gan, Shanshan Zhao, Ling Peng, Jingyang Lu, Zhiwei Wang
