Publication number: 20210263128Abstract: Systems and methods for determining an indication of locationing accuracy are disclosed herein. In some embodiments, an antenna deployment including multiple antennas and corresponding locations for the antennas is obtained. Then, one or more radio characteristics are determined for ubiety locations based on the antenna deployment and an indication of locationing accuracy for the ubiety locations is determined based on the one or more radio characteristics. In this way, an antenna deployment can be evaluated for locationing accuracy. This may be used by a network engineer or an automated system to determine and/or refine an antenna deployment.Type: ApplicationFiled: September 14, 2018Publication date: August 26, 2021Inventors: Roland Smith, Gunther Auer, Kunpeng Qi

Patent number: 10848918Abstract: Method and server are disclosed for positioning user equipment (UE). According to an embodiment, positioning-related information is collected for each of a plurality of UEs from at least one network node for at least a first duration of time. For each UE, matching positioning-related information is determined that is matched with the UE's registration address related information, wherein the plurality of UEs' registration addresses are obtained from a network provider. A reference database is created which contains, for each UE, a reference point comprising the UE's identification (ID), registration address related information and matching positioning-related information. In response to a positioning request, a UE's current positioning-related information is acquired from a network node. The UE is positioned based on its current positioning-related information and the reference database.Type: GrantFiled: February 13, 2017Date of Patent: November 24, 2020Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Kunpeng Qi, Fang Li

Patent number: 10563569Abstract: A diesel combustion system including a piston, an annular impinging block, and a combustion chamber. The combustion chamber is divided by the annular impinging block into an upper chamber and a lower chamber. The annular impinging block includes a lower guide surface that is adjacent to the lower chamber and that extends from a trough line connected to the piston to a crest line. The ratios among the inner diameter of the top of the piston, the outer diameter of the top of the piston, the diameter of the trough line, and the diameter of the crest line define the shape of the combustion chamber which leads to increased rate of combustion, reduced soot emission, and increased fuel efficiency.Type: GrantFiled: January 9, 2018Date of Patent: February 18, 2020Assignee: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Wuqiang Long, Hua Tian, Jiangping Tian, Yao Fu, Jingchen Cui, Kai Sheng, Ping Yi, Kunpeng Qi, Qiang Zhang, Yicong Wang

Publication number: 20130104850Abstract: A multi-fuel pre-mixed combustion system of an internal combustion engine includes a main fuel spray nozzle (2), which injects a mixed fuel of compression-ignition-suitable fuels, spark-ignition-suitable fuel, or a wide cut fuel to form a homogeneous primary pre-mixed gas. An auxiliary spray nozzle (4) injects a spark-ignition-suitable fuel to form a secondary mixed gas, which is ignited by the spark plug (3) by means of spray guiding or an ignition chamber (5), and the primary pre-mixed gas in the combustion chamber (1) is compression ignited. Consequently, the ignition point of the primary mixed gas is effectively controlled and knock is avoided, and a homogeneous pre-mixed compression ignition is achieved over the whole range of operating conditions. The combustion rate is controlled by exhaust gas recirculation or spray of water into a cylinder or intake port, and high thermal efficiency is ensured by a high expansion ratio.Type: ApplicationFiled: June 22, 2011Publication date: May 2, 2013Applicant: DALIAN UNIVERSITY OF TECHNOLOGYInventors: Wuqiang Long, Jiangping Tian, Xianyin Leng, Kunpeng Qi, Kai Sheng, Quan Dong
