Patent number: 11918194Abstract: An osteotomy calibration method, calibration device, and an orthopedic surgery system are provided by present application. Firstly using the osteotomy calibration device to obtain the calculated position information of the current osteotomy plane, and then determining a position error between the calculated position information and a predetermined position information of a planned osteotomy plane, and if the position error exceeds a preset value, calculating and transmitting a relocation information to a robotic arm to control and relocate the robotic arm. By comparing and identifying the position error between the current osteotomy plane formed by the first osteotomy and the planned predetermined osteotomy plane, relocating the robotic arm, and performing a secondary correction of the osteotomy plane. In addition, by relocating the robotic arm and secondary correction of the osteotomy plane, additional bone nails which is to fix the navigation tool to the bone can be avoided.Type: GrantFiled: April 23, 2020Date of Patent: March 5, 2024Assignee: SUZHOU MICROPORT ORTHOBOT CO., LTD.Inventors: Jingyang Ma, Feng Sun, Hui Shao, Chao He, Pengfei Liu

Patent number: 11817911Abstract: An active feedback control method for a quantum communication system based on machine learning is disclosed. In the transmission process of a quantum key distribution system, the present invention uses a pre-trained double-layer LSTM network to predict, according to a real-time ambient temperature, humidity and laser light intensity fluctuation, as well as voltage changes in the past moment, a zero-phase voltage value of a phase modulator at a receiving end at the next moment, and updates the network at a fixed time interval, so that the LSTM network can accurately predict for a long time, ensuring that the quantum key distribution system operates stably and efficiently for a long time. The present invention greatly improves the transmission efficiency of the quantum key distribution system by method of active prediction and feedback control.Type: GrantFiled: January 6, 2020Date of Patent: November 14, 2023Assignee: Nanjing University of Posts and TelecommunicationsInventors: Qin Wang, Jingyang Liu
