Patent number: 12127040Abstract: The present invention discloses a communication method having data transmission sorting mechanism. Whether an object under process is a mobile terminated object is determined. When the object under process is the mobile terminated object, a processing priority is set to be the highest priority, a receiving process is performed and response content is generated when required. When the object under process is a mobile originated object, a transmission process is performed, the processing priority is set according to a processing priority setting of a related transmission entity and the mobile originated object is added to a transmission list. When an object transmission is not able to be performed, the response content is added to a response list. When the object transmission is able to be performed, the response content in the response list is transmitted first and the mobile originated object in the transmission list is transmitted subsequently.Type: GrantFiled: May 16, 2022Date of Patent: October 22, 2024Assignee: REALTEK SEMICONDUCTOR CORPORATIONInventors: Chin Cheng, Yi-Xin Huang, Xiao-Lu Ma

Patent number: 12085535Abstract: Apparatus and method are provided wherein by measuring both the electrical permittivity and the electrical conductivity of the measured multiphase fluid, the resultant amplitude and phase angle of the induced complex voltage can be analysed. The phase angle data can be analysed to provide information on the electrically conductive phase, and that information can be employed to analyse the amplitude data, in particular to use the information on the electrically conductive phase to determine the contribution to the amplitude data by the electrically non-conductive phase. This analytical technique enables the electrical permittivity of the electrically non-conductive phase to be accurately determined. By determining the degree of contribution to the complex voltage measurement by both the permittivity and the conductivity, enhanced measurement accuracy of a multiphase fluid can be achieved.Type: GrantFiled: December 18, 2020Date of Patent: September 10, 2024Assignee: ENERCORP ENGINEERED SOLUTIONS, LLCInventors: Lu Ma, Yessica Arellano
