The 49th Geneva International Invention Exhibition closed on the 21st in Geneva, Switzerland. The Chinese delegation participated with 197 inventions and won a total of 70 gold and 97 silver awards. The "Atmospheric Multiparameter Detection Quantum Lidar" project from the School of Earth and Space Sciences at the University of Science and Technology of China has won both the gold award and the "Geneva Republic and State Government Award", one of the special awards at this year's Invention Exhibition. This project can achieve high-precision detection of carbon dioxide concentration, aerosol concentration, and atmospheric wind field within a detection radius of 3 kilometers, significantly improving the digital and refined management level in the field of meteorological and environmental protection. Six participating projects of China Electric Power Research Institute have won 5 gold and 1 silver awards, covering various aspects of power system generation, transmission, distribution, and utilization, demonstrating the innovative achievements and strong scientific research strength of State Grid Corporation of China in building a new type of power system and a strong digital power grid. The audio and video fusion intelligent earphones developed by Tianjin (Binhai) Artificial Intelligence Innovation Center for special application scenarios not only won the gold award, but also received a special award. This invention can meet the voice interaction needs in silent and high noise special working environments, and has broad market space and application prospects in fields such as public security emergency firefighting and counter-terrorism. The Geneva International Invention Exhibition was founded in the 1970s and is one of the longest and largest invention exhibitions in the world. It is reported that more than 1000 inventions from around the world will be exhibited at this exhibition. (Lai Xin She)
