Techniques for detecting foreign objects in a charging path of a wireless power transfer system are disclosed. An example apparatus for detecting a presence of a foreign object includes a foreign object detection (FOD) system, a living object protection (LOP) system, a control circuit operably coupled to the FOD system and the LOP system and configured to detect a change in one or more power transfer parameters, perform a calibration procedure on the FOD system based on the change in the one or more power transfer parameters, operate the LOP system in a high sensitivity mode concurrently with the calibration procedure, and operate the LOP system in a standard detection mode upon completing the calibration procedure.
