Patent number: 11951618Abstract: A multi-procedure integrated automatic production line for hard alloy blades under robot control is provided. The production line includes a rail-guided robot. A cutter passivation device and a blade cleaning and drying device are arranged on one side of the rail-guided robot. A blade-coating transfer table, a blade coating device, a blade boxing transfer table, a blade-tooling dismounting device and a blade boxing device are sequentially arranged on another side of the rail-guided robot. The blade-tooling dismounting device is arranged on one side of the blade boxing transfer table. The production line further includes squirrel-cage toolings for carrying the blades. The squirrel-cage tooling that are loaded with the blades can run among the cutter passivation device, the blade cleaning and drying device, the blade-coating transfer table and the blade boxing transfer table. The blades after being treated through the blade-tooling dismounting device are sent to the blade boxing device.Type: GrantFiled: August 17, 2021Date of Patent: April 9, 2024Assignees: Qingdao University of Technology, Ningbo Sanhan Alloy Material Co., Ltd.Inventors: Changhe Li, Teng Gao, Liang Luo, Lizhi Tang, Yanbin Zhang, Weixi Ji, Binhui Wan, Shuo Yin, Huajun Cao, Bingheng Lu, Xin Cui, Mingzheng Liu, Jie Xu, Huiming Luo, Haizhou Xu, Min Yang, Huaping Hong, Yuying Yang, Haogang Li, Wuxing Ma, Shuai Chen

Publication number: 20230371013Abstract: A resource allocation method, a device, and a storage medium are disclosed. The method includes: A network device obtains a packet concurrency status of a plurality of wireless local area network WLAN devices, where the plurality of WLAN devices correspond to a same channel. The network device allocates channel resource slices to the plurality of WLAN devices from a channel resource in a first time period based on the packet concurrency status.Type: ApplicationFiled: May 10, 2023Publication date: November 16, 2023Inventors: Shuaishuai Zhang, Chun Pan, Weixi Chen, Xingfeng Jiang, Rihai Wu, Hongyi Tan

Publication number: 20230345282Abstract: A method and an apparatus for detecting co-channel interference in a WLAN are provided. The method provided herein includes: A communication device detects a first energy value and a second energy value, where the first energy value is an energy value of a signal on a channel before a WLAN frame is sent, and the second energy value is an energy value of a signal on the channel after the WLAN frame is sent. The communication device determines, based on the first energy value and the second energy value, that the WLAN frame is subject to interference.Type: ApplicationFiled: April 21, 2023Publication date: October 26, 2023Inventors: Ran Sang, Weixi Chen, Wei Zhang

Patent number: 11190406Abstract: A virtual network comprising virtual machines executing at a computing environment is implemented. A flexibly extensible NIC (eNIC) is executed at a software defined networking (SDN) appliance. A data packet is received that is addressed to a host that is connected to the virtual network. Based on a layer 2 address and a network identifier, the virtual switch identifies the host represented by the eNIC that is associated with the data packet. A policy associated with the host is determined and applied to the data packet. The policy is dynamically adjustable based on the host.Type: GrantFiled: December 1, 2020Date of Patent: November 30, 2021Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Rishabh Tewari, Sumit Sharad Dhoble, Madhan Sivakumar, Manasi Deval, Avijit Gupta, Pranjal Shrivastava, Zexuan Zhao, Jun Tse Chen, Sirshak Das, Sahil Aggarwal, Weixi Chen, Bhushan Vinayak Bhise, Devan Harikumar, Arun Jeedigunta Venkata Satya, Deepak Bansal

Patent number: 7939352Abstract: A method for fabricating a selective area metal bonding Si-based laser, optically or electrically pumped includes: forming a Si waveguide area and a bonding area in a Silicon-On-Insulator (SOI) wafer, and forming an isolating structure to separate the Si waveguide area from the bonding area; forming a metal multilayer for bonding, which also acts as ohmic contact layer in the laser when the laser is electrically pumped. A compound semiconductor optical gain structure is prepared by epitaxial growth and etched off the substrate. The compound semiconductor optical gain structure is aligned with the Si waveguide area in the SOI wafer and the compound semiconductor optical gain structure is bonded on the SOI wafer. The selective area metal bonding Si-based laser can be used as a light source in optoelectronic integration and Si photonics. The method may provide simple operation, flexibility, low cost, and low requirement for cleanness of manufacturing environments.Type: GrantFiled: August 11, 2009Date of Patent: May 10, 2011Assignee: Peking UniversityInventors: Guogang Qin, Tao Hong, Ting Chen, Guangzhao Ran, Weixi Chen
