OUC-Raman (OUC, Ocean University of China) underwater detection system based on Raman-spectroscopy is designed to operate as instrument node in seafloor cabled observatory network. Considering requirement and standard of seafloor cabled observatory network, this article designs control system for OUC-Raman. It's composed of power management module and control module. Power management module ensures...
A new deep-sea hybrid Raman insertion probe (RiP) has been developed by the Institute of Oceanology, Chinese Academy of Sciences (IOCAS) and the Ocean University of China (OUC) for the detection of the hydrothermal vent, cold seep fluid and sediment pore water geochemistry. The novel probe can work at temperature range from 0 to 450 °C with water depth to 4500 m.
With the heated trend of augmented reality (AR) and popularity of smart head-mounted devices, the development of natural human device interaction is important, especially the hand gesture based interaction. This paper presents a solution for the point gesture based interaction in the egocentric vision and its application. Firstly, a dataset named EgoFinger is established focusing on the pointing gesture...
Flyback topologies are widely used in low power applications due to the small size and low cost. To improve the efficiency via reducing the switching loss, valley switching technique is introduced and several methods to realize valley switching are analysed and compared. Besides, the matter of frequency under light load condition is described, which can be solved by valley skipping technique, whereas...
In this paper, we introduce a new approach to finger key point detection. For RGB images captured from an egocentric vision with a mobile camera, fingertip point detection remains a challenging problem due to various factors, like background complexity, illumination variety, hand shape diversity, and image blur cause by camera movements. To address these issues, we propose a bi-level cascade structure...
