  "textContent": "A system including a power device and a portable device for wireless powering of a load of the portable device is provided. The power device includes a transmitter stage to generate a carrier signal and an antenna connected to the transmitter stage to emit a magnetic field with a first waveform of the carrier signal. The portable device includes an antenna exposed to the magnetic field of the power device to receive an antenna signal and a receiver stage connected to the antenna to rectify the antenna signal to provide power to the load of the portable device. The power device is built to emit the magnetic field with the first waveform of the carrier signal in a power transfer mode and to emit the magnetic field with a second waveform of the carrier signal in a communication mode.",
