Beschreibung
Zusammenfassung:	An object detection system 200 for an inductive power transmitter and comprising: an excitation coil 202; a detection coil 204; the system arranged to determine a measure of complex impedance at the detection coil 204 in response to application of an excitation current to the excitation coil 202; the system further arranged to detect the presence of an object and a type of the object using the measure of complex impedance.
