Abstract
A cooking article detection system for an induction cooktop having a first power-delivery induction coil includes a first detector coil overlying the first power-delivery induction coil and including a first conductive element revolving continuously around a centroid in a first tangential direction to define a shape of the first coil that extends in a first linear direction and a second linear direction along a plane and a second detector coil overlying the first power-delivery coil and including a second conductive element connected with the first detector coils and revolving continuously around a centroid in a second tangential direction, opposite the first tangential direction. The second detector coil is linearly arranged with the first detector coil and is spaced apart therefrom in the second linear direction. A controller drives the first and second detection coils, simultaneously, with a low-voltage, high frequency detection signal, and measures a voltage across the first and second detection coils to identify a cooking article on the induction cooktop.
