Publication number: 20230187030Abstract: The present disclosure belongs to the technical field of food processing, and in particular relates to a rapid and non-destructive quantitative evaluation method for taste characteristics of fried rice. The method includes three steps: constructing a quantitative model of seasoning for the fried rice, constructing a model for identifying types of materials of the fried rice, and performing quantitative characterization of the taste characteristics of the fried rice. The quantitative model of the seasoning is established based on sensitivity of a spectral signal to changes of the content of seasoning liquid. An analytic equation of key parameters of the quantitative model of the seasoning is established according to characteristics that the total amount of the seasoning in finished fried rice is equal to the total amount of the seasoning added during frying of the fried rice. The quantitative model of the seasoning is rapidly constructed by solving the equations.Type: ApplicationFiled: December 7, 2021Publication date: June 15, 2023Applicant: Jiangsu UniversityInventors: Jiyong SHI, Xiaobo ZOU, Xiaowei HUANG, Zhihua LI, Tingting SHEN, Xin LI, Pengjing CUI, Jianbo XIAO, Xinai ZHANG, Di ZHANG, Chenguang ZHOU, Yang ZHANG, Mengxue LIU

Patent number: 10199725Abstract: Systems and related methods for reducing passive intermodulation (PIM) include a combination of an antenna control unit (ACU) and a remote electrical tilt (RET) system. The ACU may be used to generate rotational motion of an output drive shaft in response to an input tilt control signal. The RET system couples to the output drive shaft of the ACU and may be used to convert the rotational motion into translational motion for modifying a phase shift of an antenna beam. PIM may be substantially eliminated by providing electrical isolation between the ACU and RET system in the form of a non-conductive connector that engages the draft shaft of the ACU.Type: GrantFiled: November 12, 2013Date of Patent: February 5, 2019Inventors: Asaad R. Elsaadani, Timothy Bernhardt, Peter A. Casey, Chenguang Zhou, Peng Cui, Gaetan G. F. Fauquert, Eric Callec

Patent number: 10027022Abstract: The present disclosure relates to an antenna for a wireless communication system. The antenna comprises a reflector having a front side for transmitting a signal and a back side opposite to the front side; an antenna oscillator disposed on the front side of the reflector; a phase shifter network disposed on the back side of the reflector; and an antenna oscillator fixing apparatus disposed on the front side of the reflector and configured to fix the antenna oscillator to the front side of the reflector. In addition, the present disclosure also relates to a method for fixing an antenna oscillator to a reflector. With the antenna and the fixing method according to the present disclosure, it is possible to manufacture an antenna with an antenna oscillator that is easy to dismantle without damaging an existing phase shifter network, which will improve maintainability of the antenna according to the present disclosure dramatically and also reduce the cost of maintenance and repairs.Type: GrantFiled: November 4, 2014Date of Patent: July 17, 2018Assignee: Alcatel LucentInventors: Chenguang Zhou, Bo Zhao, Beiming Xu
