Static wireless charging is becoming popular all over the world to charge the electric vehicle (EV). But an EV cannot go too far with a full charge. It will need more batteries to increase its range. Dynamic wireless charging is introduced to EVs to capitally increase their driving range and get rid...

The aim of this work is to develop a device for the safety and protection of women and girls. Indeed, even today, an evil break is made when ladies venture out with a niggling apprehension in their brains about their safety. We regularly find out about rape cases that make our blood run cold. It is ...
