Publication number: 20180343769Abstract: A radiator includes a radiating part including a housing and a set of blades arranged on the inner surface of the housing; and a heat conductive part. The heat conductive part includes a shell including a heat conductive surface, configured to be in contact with a heat source, and a receiving section with two open ends. The receiving section is configured to receive the radiating part. In an embodiment, the radiating part is rotatablely fixed on the receiving section of the heat conductive part such that, when the radiating part rotates, fluid can be drawn into one end of the receiving section and then blown out at the other end by the blades. The radiating part is able to exchange heat constantly with new fluid and the rotation of the blades can expel the fluid with higher temperature and draw in fluid with lower temperature to perform new heat exchange.Type: ApplicationFiled: February 16, 2016Publication date: November 29, 2018Applicant: Siemens AktiengesellschaftInventor: Yan Heng ZHOU

Patent number: 9277430Abstract: Aspects of the methods and apparatus include determining that a time-to-trigger (TTT) timer has expired, and determining that a serving radio access technology (RAT) received signal characteristic is less than a signal characteristic threshold when the TTT timer has expired. Further, the aspects include determining, in response to the serving RAT received signal characteristic being less than the signal characteristic threshold, that a target RAT frequency measurement associated with a Measurement Report Message (MRM) for performing an inter-RAT (IRAT) handover cannot be completed within a time limit according to a current measurement gap configuration. Also, the aspects include calculating a measurement gap duration sufficient to complete the target RAT frequency measurement associated with the MRM for performing the IRAT handover, and configuring a new measurement gap prior to the time limit, wherein the new measurement gap comprises the calculated measurement gap duration.Type: GrantFiled: April 2, 2014Date of Patent: March 1, 2016Assignee: QUALCOMM IncorporatedInventors: Thawatt Gopal, Heng Zhou, Qingxin Chen, Yu Fu, Tom Chin, Zhengming Li

Patent number: 8854161Abstract: The present invention provides a wideband frequency tunable ring resonator, wherein, comprises a closed ?g/2 transmission line and two variable capacitors with tunable capacitance, the ?g/2 transmission line is axisymmetric around a central line, first ends of the two variable capacitors are respectively connected to two intersection points of the ?g/2 transmission line and the central line, the second ends of the two variable capacitors are respectively grounded. By implementing the technical solution of present invention, following technical effects are obtained. The fundamental resonant frequency (ffund) can be shifted up and down by controlling the respective values of the two loading capacitors, resulting in a bi-directional tuning of ffund. As a result, the tuning range of this invention can be approximately doubled as compared with the conventional tunable ring resonator.Type: GrantFiled: September 22, 2011Date of Patent: October 7, 2014Assignee: Nantong UniversityInventors: Jian Xin Chen, Li Heng Zhou, Hui Tang, Zhi Hua Bao, Yong Jie Yang, Quan Xue

Publication number: 20120113826Abstract: In certain wireless communications systems, such as TD-SCDMA, frames are divided into sections allocated for various communication purposes such as uplink and downlink transmissions. In such schemes, there may be no mechanism to generate gaps for a UE to employ for non-allocated purposes, such as inter-frequency or inter-RAT measurement. To generate gaps for such purposes the UE may employ rate-matching techniques to take certain allocated time slots for the UE and reserve them for inter-RAT measurement or other purposes. The rate-matching techniques generate unconfigured slots.Type: ApplicationFiled: November 8, 2010Publication date: May 10, 2012Inventors: Heng Zhou, Tom Chin, Shan Qing
