This paper describes a novel data transmission system for the air-cushion type biomedical measurement system. Conversational data transmission via coaxial cable sometimes intimidates the patients; the electric cable near the bed is not desirable for medical doctors and nurses, either. To solve this problem, we developed an FM transmission system that is battery driven and transmits signals from DC...Show More
Further developments and experiments of the laser current transformer for extra-high-voltage power transmission lines are described. A developmental model for reproduction of a large current waveform of extra-high-voltage is constructed by using a 6328-Å gas laser beam and a flint glass rod fixed on the top of 30-cm-diameter supporting insulators. It was tested at the Shiobara Laboratory of the Ce...Show More
