The rapid development of mobile telecommunication industry has brought great convenience to people's lives, and even progressively have changed our way of life. With the continuous improvement regarding coverage area, internet speed etc. of requirements, there are more and more mobile base stations, and the issue concerning the electromagnetic radiation of mobile base station is also of very high...
Electromagnetic radiation has been recognized by more and more people and has made them feel frightened. Even in some cities, such phenomena have taken place that residents urge to remove established base stations, cut off feeder lines or prevent new base stations from being set up. Due to lack of in-depth research on electromagnetic radiation around base stations, communication operators in China...
Since 1960s, no solutions have been found both home and abroad to the theory and protective technology related to hazard influences of a high voltage transmission system on a communication system. Previously, the major technical measure against comprehensive hazards of the strong current is to make them separated. However, in city planning, it is inevitable to arrange them closely or construct them...
A head attitudes measurement system based on 3-axis micro-accelerometer and 3-axis micro-magnetoresistive sensor is designed and developed using for thermal imager setup of night-driving vehicle. The three attitude angles, i.e. pitch, roll and yaw, of driver's head are estimated relative to the driving vehicle in real time. In this system, the 3-axis micro-accelerometer detects the gravity field and...
