Abstract
A system for resupplying power to self-contained mobile equipment, including a fixed station having an external power source and consisting of a high-frequency generator and an induction coil as well as, on or in the equipment, a pick-up coil, a current filtering and rectifying device, a rechargeable battery pack, and a microcomputer-controlled tracking system. The microcomputer is connected to the drive control system of the equipment and applies a drive algorithm to the fixed station when the battery charge level drops below a predetermined level, the algorithm being based on a measurement of the high-frequency generator signal reception strength gradient.
