Electro-accel pedal is needed to raise fuel efficiency by controlled pedal angle signal regardless driver’s willings to fast start or stop pedaling, and to reduce muscle fatigue by designed Ergonomic structure. For this purpose, in this study, we designed new mechanism of accel pedal in a double linkage with two springs to minimize the force of pedaling on main pedal period for HECV in close the future. We have achieved the simulation to dynamic characteristics and experimented to measure the pedal force with proto sample, and confirmed the potentialities this new mechanism.

The Blandford-Znajek process, which extracts the rotational energy of the supermassive black hole at the center of an active galactic nucleus, is now well explained and educated through the electronic circuit analysis established by Macdonald and Thorne. The Macdonald-Thorne circuits consist of the batteries and resistances of the central black hole and the astrophysical region around the accretion disk. In this letter we will consider the possibility whether we can connect coils and condensers in such circuits or not. If possible, that may explain a sudden corona-phenomenon in an active galactic nucleus. We conclude that a flash of order ~5×1040ergss−1 can occur around a \~109M⨀ \~109M⨀ black hole through this process.
