  "textContent": "A wireless power transfer system includes a power transmitter () arranged to provide a power transfer to a power receiver () via a power transfer signal. The power receiver () comprises a first mode controller () for transmitting a standby mode exit request to the power transmitter () by changing a loading of a communication inductor () of the power transmitter (). The power transmitter () comprises a mode controller () which controls the power transmitter () to operate in a standby mode wherein a presence of the power receiver () is detected but no power transfer signal is generated. It furthermore comprises a detector () for detecting an impedance change of the communication inductor (). The mode controller () is arranged to initiate a transition from the standby mode to a power transfer mode in response to the detector () detecting the impedance change.",
