Abstract
An apparatus is provided for detecting movement of a vessel positioned on a cooktop surface. The apparatus includes a resonant circuit that has at least an inductive loop positioned proximate to the cooktop surface. A signal conditioner is connected to the resonant circuit for conditioning signals received from the resonant circuit. A processor is connected to the signal conditioner and compares the conditioned signals received from the signal conditioner to a reference signal whereby detecting movement of the vessel.
