Patent number: 11101826Abstract: A radio frequency (RF) control circuit is disclosed. The RF control circuit includes a transceiver module and a front-end module. The front-end module is connected to the transceiver module via a primary component carrier (PCC) path and a secondary component carrier (SCC) path. The front-end module is configured to receive an external data signal and transmit a local data signal. The transceiver module is configured to receive a PCC signal from the external data signal and transmitting the PCC signal from the local data signal through the PCC path and receiving a SCC signal from the external data signal and transmitting the SCC signal from the local data signal through the SCC path. The SCC path is controlled to be grounded such that interference of the local data signal for the PCC path on the external data signal for the SCC path is eliminated. A mobile terminal is also disclosed.Type: GrantFiled: January 30, 2019Date of Patent: August 24, 2021Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.Inventors: Qiuwen Liu, Xianlong Chen, Jiafeng Yang, Xianping Xiong, Guoxi Zhang, Shaoming Pang

Patent number: 8343006Abstract: A transmission includes an input shaft (IP), an output shaft (OP), a single planetary gearset (SP), a compound planetary gearset (CP), shifting elements. The single planetary gearset is arranged before the compound planetary gearset, and the shifting elements comprise at least two brakes (B1,B2), the first clutch (C1), the second clutch (C2), the third clutch (C3), and all the shifting elements are positioned between the single planetary gearset and the compound planetary gearset, which has compact arrangements, and can reduce the power transmission length. The transmission also includes an one-way clutch (OWC) acted on the compound planetary gearset.Type: GrantFiled: December 4, 2008Date of Patent: January 1, 2013Assignee: Chery Automobile Co., Ltd.Inventors: Jiafeng Yang, Bill Lakis, Andrew Nowacki, Sarah Wykes, Chris Reis, John Stokes, Frank Bauer, Jian Lin
