The invention discloses an infant airway collaborative intubation safety control system based on different-place mixed reality. The system aims at solving the problems of space synchronization robustness and predictive time delay compensation in remote guidance, a mapping relation between a local coordinate system and a remote coordinate system is established through a space synchronization module, a long short-term memory (LSTM) network is used for predictive compensation of a remote expert track, and visual lag is eliminated. The core safety mechanism comprises the steps that the airway dynamic model module generates a real-time dynamic signed distance field (D-SDF); the risk prediction module calculates the dynamic collision risk probability of the laryngoscope tail end and the dynamic airway wall in real time. The tactile feedback device responds to the risk probability, adopts a variable admittance control strategy, generates an operation viscous sense by nonlinearly increasing virtual damping, and activates a virtual stiffness item pointing to a safety area when the risk exceeds a critical value, so as to apply a reverse elastic restoring force and realize active safety avoidance in a physical level. And the submillimeter precision and safety of the airway operation of the infant are ensured.

A system for guiding a drone to an intended destination using a remote guidance system, independent of a global positioning system installed on the drone and independent of radio guidance. The system uses a two-way optical communication channel between the guidance system and the drone. The drone and the guidance system each have a light source emitting a beam of encoded light, such as a modulated laser beam, and having an extended field of illumination, and a detector receiving the impinging light beam. The guidance system can detect the angular location of the drone emission, and can transmit instructions optically to the drone, while the drone can receive flight path instructions from the guidance system. The drone can be launched from a position that is not in the line of sight of its intended destination and guided optically from the launch position to its intended target destination.

According to the remote monitoring system and method for the in-vitro liver perfusion equipment, medical staff can move and operate a tablet personal computer within a certain range in an operating room without constraint of the physical position of an equipment host, a patient and the equipment can be taken into consideration at the same time, it can be guaranteed that the equipment is normally controlled in a small space or in a multi-person operation scene, and the operation efficiency is improved. The flexibility of the working process is improved; through the Internet cloud, remote specialists can observe the whole perfusion process in real time as if they are personally on site, so that instant remote guidance is provided for evaluation of marginal donor liver and processing of complex conditions, and the utilization efficiency and the treatment level of medical resources are improved; the dual network architecture provides communication redundancy to a certain extent. Based on the alarm pushing function of the cloud platform, 7 * 24-hour state monitoring is realized, even if field personnel leave temporarily, key alarms can be known in time through mobile phones, and the safety is greatly improved.
