  "textContent": "Foreign object detection for wireless power transmitters and related apparatuses and methods are disclosed. An apparatus includes an analog-to-digital converter to sample at least one of a coil voltage potential and a coil current representation of a transmit coil inductively coupled to a receive coil of a wireless power receiver with a distance between the transmit coil and the receive coil. The apparatus also includes a processing core to determine an expected reference Q-factor value responsive to the at least one of the sampled coil voltage potential and the sampled coil current representation. The expected reference Q-factor value indicates a Q-factor value expected at a predetermined reference wireless power transmitter inductively coupled to the wireless power receiver with a reference distance from a reference transmit coil of the predetermined reference wireless power transmitter to the receive coil of the wireless power receiver.",
