Study of technological knowledge diffusion can provide a basis for R&D planners to invest new R&D projects with a proper direction. In this paper, we introduce a modified method to analyze the diffusion degree of technological knowledge among different technological fields using patent data at the technology patent class level. This method first generates a patent citation network related...
In recent years, the developing speed of emerging technologies keep accelerating. Correctly understanding the future trend of technologies can help the government and enterprises formulate R&D strategies, and then seize the chance. Therefore, the research in Technology Trend has increasingly becomes a hotspot in technology management. First, the article puts forward four main aspects that technological...
The small-size unmanned helicopters have good application values in many areas. A beyond-visual-range controlled helicopter display system framework is built. By acquisition of signals of angle sensor, magnetoresistive sensor, GPS module, the flying information of pitch, incline, direction, position, etc. in helicopter is gotten in the system. The signals coded by single-chip microcomputer are wirelessly...
