Many scientific researches require the observation of microscopic images of samples under high magnetic fields. Due to the strong effect of high magnetic fields on magnetic materials and electronic devices, such microscopy imaging system is completely different from conventional systems. In order to control of the imaging system and the acquisition of microscopic image data under high magnetic fields, we developed a control software based on Python. This software provides functionalities such as monitoring the magnet status, controlling piezoelectric displacement devices, and real-time image monitoring. It further use an automatic focusing algorithm, in conjunction with piezoelectric displacement devices, to automatically focus optical images under high magnetic fields. Experimental results indicate that this software is capable of imaging samples under magnetic fields, thereby laying the foundation for the exploration of microscopic changes in samples under high magnetic field conditions.

This study designs a variable configuration for a bionic aerial-aquatic cross-media vehicle, providing a crucial platform support for the research of cross-media key technologies. Utilizing computational fluid dynamics (CFD) simulation technology, the aero-dynamic characteristics of the prototype at different speeds were analyzed, and the final prototype was successfully developed and tested in flight experiments. The experimental results demonstrate that the aerial-aquatic vehicle can complete the transition between the aerial and aquatic navigation modes through the deformation ability. The maximum flight speed in the air reaches 104 km/h, and when the cruise speed is greater than 54 km/h, the lift-to-drag ratio is greater than 18.623, indicating a good aerodynamic characteristic.

Traditional teleoperation technologies based on video streaming are facing several challenges in practical applications, including limited bandwidth, constrained spatial awareness, and sensitivity to illumination. Existing studies have not adequately addressed these issues. This paper presents a novel non-video based teleoperation framework for autonomous vehicles operating in bandwidth-limited environments. To reduce the amount of data being transmitted, a persistent-transient environment model is proposed for telepresence. Initially, a digital twin of the environment is preconstructed, containing only persistent environmental information. Subsequently, transient information captured by onboard sensors, such as vehicle state and dynamic objects, necessitate real-time transmission. Based on this model, a 3D virtual scene is rendered in front of the teleoperator, offering any desired virtual viewpoint to enhance spatial awareness. This telepresence model only requires real-time transmission of minimal data, i.e., vehicle state and detected objects, and remains unaffected by illumination conditions, enabling teleoperation even in applications with Kbps-level bandwidth constraints. Experimental results showcase the substantial potential of the proposed framework in bandwidth-limited settings.
