Abstract: A balance disorder rehabilitation robot based on virtual and real scene fusion has a follow-up supporting device, a weight loss protection device and a virtual projection device. The follow-up supporting device is arranged in the center position of a bottom surface of the weight loss protection device and is used to follow the balance training gait of a patient in real time. The weight loss protection device is used to follow the position of center of gravity of the patient in a process of balance rehabilitation training in real time. The virtual projection device is arranged in front of the follow-up supporting device to present a virtual scene. The postures and the positions of the follow-up platforms are controlled to realize the physical sense reproduction of multiple motion scenes. The physical scene is organically combined with the virtual scene to ensure a diverse balance rehabilitation training environment.

Abstract: A video generation method includes: obtaining a target face image and a source face image; extracting a feature of each of the source face image and the target face image through a face feature encoder, to obtain corresponding source feature codes and target feature codes; generating swapped face feature codes through a face feature exchanger according to the source feature codes and the target feature codes; generating an initial swapped face image through a face generator according to the swapped face feature codes; and fusing the initial swapped face image with the target face image through a face fuser, to obtain a final swapped face image. The face feature encoder performs hierarchical encoding on the face feature to reserve semantic details of a face, and the face feature exchanger performs further processing based on the hierarchical encoding, to obtain hierarchical encoding of a swapped face feature with semantic details.

Abstract: An atomic force microscope has dual probes composed of a hinge structure, two cantilever beams and needle tips arranged on free ends of the cantilever beams. The hinge structure is a U-shaped body having two ends respectively extended with a first cantilever beam and a second cantilever beam. The free end of the first cantilever beam and the free end of the second cantilever beam are respectively provided with a first needle tip and a second needle tip. The integrated dual probes is operated by the driving function of the probe clamp. Therefore, only a set of motion control and measurement system of the atomic force microscope is required to realize the rapid in-situ switching function of the dual probes.
