The optimal designs are investigated for a wireless resonant energy link (WREL) based on a nonradiative magnetic field. Internal resistance of coils is considered in relation to the coil configuration. As a result, the designs are obtained for the transmission efficiency maximum or for the effective power supply maximum. In addition, it is found that any combination of the efficiency and power supply...
In this automatic power supply system, the specific gravity, level and temperature of the electrolyte are detected by newly developed sensors. The data from these sensors are analyzed, and the specific gravity and level are always displayed and the temperature is displayed in abnormal conditions. The discharge capacity at occasional discharge operation is memorized by IC installed and suitable charge...
