폴리머 전기광학 변조기는 넓은 변조대역, 낮은 구동전압, 빠른 응답속도, 및 쉬운 공정등의 잇점 때문에 관심이 집중되어 많은 연구가 되어져 왔다. 최근에는 1000Hz 이상에서 동작하거나 1V 이하의 구동전압을 갖는 폴리머 광 변조기가 보고된바 있으며 이는 저가의 광 변조기 개발의 가능성을 보여준다. 그러나 폴리머 광 변조기는 기존의 광 변조기들에 비해 광 전파손실이 크고 열적 안정성이 낮다는 문제점등이 있다. (중략)

Atmospheric pressure in a tunnel rises in proportion to the square of train’s speed as it enters a tunnel. This pressure difference propagates into the train and cause aural discomfort to the passengers. In order to alleviate the aural discomfort of them. a new ventilation system has been designed and tested. This system controls the charged and discharged by flow rate by detecting the air pressure generated outside and inside of the train. Test to confirm the fundamental performance of the system was carried out. Consequently, this system was found to be able to alleviate the aural discomfort effectively. Application of the system to TGV-K running in the speed range of 350km/h is considered to have good propospect.
