US Patent 11682930 Repeater compatibility verifier for wireless power transmission system

A modular wireless power transfer system includes a first wireless transmission system and a wireless repeater system. The first wireless transmission system is configured to receive input power from an input power source, generate AC wireless signals, and couple with the wireless repeater system. A magnetic sensor system in the first wireless transmission system senses a magnet of specific strength in a specific location on the wireless repeater system. Based on the presence of absence of such a magnet, the first wireless transmission system allows or disallows, respectively, the transmission of the AC wireless signals to the wireless repeater system.
