    Abstract: A cooktop assembly includes a cooking panel. A heating element is operably coupled to the cooking panel. The heating element forms a heating zone for said cooktop assembly. A support surface extends over the heating element for supporting a cooking vessel thereon. The support surface includes a heating zone surface in the heating zone, a surrounding surface outside the heating zone, and a surface discontinuity defining a kinesthetic feature providing feedback for demarcating the heating zone relative to the surrounding surface and positioning the cooking vessel relative to the heating zone and, consequently, the heating element.

    Abstract: A household appliance power supply device and method are disclosed. The power supply device comprises a switching converter having an input filtering stage; and a determining means configured to obtain estimation data indicative of the input current that is adsorbed from the a main power input, on the base of the rate of change of the bus voltage across said bus capacitor respectively, during a second switching period. The switching converter further comprises a bus capacitor, electrically connected with at least one output terminal of a rectifying stage, a resonant tank, electrically connected with said bus capacitor, and a switching device electrically connected with said resonant tank, said switching device being operated with a switching cycle having a first switching period, and a second switching period.

    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.
