DEVICE FOR REMOTE TRANSFER OF ENERGY TO A MOVING OBJECT BY ACOUSTIC WAVES

摘要

The invention consists of a system allowing remote wireless transfer of energy from a base station to a moving object, in particular a drone, moving in a given zone around the base station. The system includes means for tracking the moving object relative to the base station at any time, means for transmitting a synthetic acoustic wave focused in the direction of the moving object, these two means being located at the base station and powered by the base station, and acoustic reception means, located on the moving object, for receiving the acoustic wave transmitted by the base station and converting the received acoustic wave into an electrical signal and then into a power supply voltage for a battery.

1. A system for remotely and wirelessly transferring energy from a base station to a mobile object moving in a given area of space around the base station, comprising:
means for emitting a synthetic acoustic wave that is focused in a given direction, which means being located at the level of the base station and supplied with power by the latter; acoustic receiving means, located at the level of the mobile object, for receiving the acoustic wave emitted by the base station and for converting the acoustic wave to an electrical signal;the system further comprises means for tracking the mobile object so as to determine the position of the mobile object with respect to the base station.
