Patent number: 12355490Abstract: A multi-channel radio frequency transceiving device includes an optical module, a digital signal processing module, a radio frequency transceiving module, a downlink module, and a microprocessing module. The optical module receives an optical signal corresponding to baseband data, converts the optical signal into an electric signal, and outputs the electric signal to the digital signal processing module. The digital signal processing module obtains the baseband data and channel number information on the basis of the electric signal, and allocates and processes the baseband data. The microprocessing module determines the number of working channels of the radio frequency transceiving module, the corresponding number of working channels of the downlink module and a downlink output power on the basis of the channel number information and the baseband data, and closes the remaining channels in the downlink module.Type: GrantFiled: December 15, 2021Date of Patent: July 8, 2025Assignee: COMBA NETWORK SYSTEMS COMPANY LIMITEDInventors: Jiangtao Liu, Qiyan Fan, Jinxiong Zhu, Weidong Zhong

Patent number: 11909443Abstract: An ROF communication remote machine and an ROF system are disclosed. The machine comprises a first packaging module and a second packaging module. The first packaging module comprises a first branch and a second branch. The first branch is used for converting a downlink optical signal, and sending the downlink electrical signal to the second packaging module. The second branch receives the downlink electrical signal, converts the downlink electrical signal into a downlink optical signal, sends the downlink optical signal to the local machine, receives an uplink electrical signal, and sends the uplink electrical signal to the local machine. The second packaging module is used for amplifying the power of the downlink electrical signal, filtering the downlink electrical signal, then feeding back the downlink electrical signal to another component, receiving the uplink electrical signal, and sending the uplink electrical signal to the second port.Type: GrantFiled: December 11, 2019Date of Patent: February 20, 2024Assignee: Comba Network Systems Company LimitedInventors: Weidong Zhong, Shangkun Wu, Yangyang Li, Li Fan

Publication number: 20230384925Abstract: In one aspect of the present disclosure, a method of acquiring gesture data is provided. The method may include acquiring a gesture signal. The method may include acquiring a feature value corresponding to the gesture signal. The method may include acquiring a signal state corresponding to a feature point based on the feature value, adding the feature value and the signal state to a gesture signal set. The method may include acquiring all feature values and all signal states between a gesture start point and a gesture end point in the phase of acquiring the gesture data from the gesture signal set. The method may include generating signal change information based on the all feature values and the all signal states. The method may include identifying the signal change information as a signal data segment of a target gesture in response to the signal change information meeting signal verification information.Type: ApplicationFiled: August 9, 2023Publication date: November 30, 2023Inventors: Ming CHEN, Li ZENG, Xiaofan ZHANG, Weidong ZHONG
