    Abstract: The present invention relates to a sensor means (11, 35, 49, 71) or module for determining a particularly elastic displacement or deflection or bending of a panel (3), in particular a glass panel, or of a section of a panel or of an insert in relation to the panel (3). The sensor means (11, 35, 49, 71) or module and the panel (3) or said section thereof forming a weighing means, in particular a scale. The sensor means (11, 35, 49, 71) or module is adapted to be integrated in or allocated to a household appliance (1), in particular a cooking hob, more in particular an induction cooking hob, and comprises or is connected to at least one processing and/or interpretation and/or compilation means, preferably for providing a particular high sensor sensitivity and/or evaluation unit accuracy. Further, a household appliance (1) is disclosed which comprises an at least approximately horizontal panel (3), in particular a glass panel. The panel (3) is part of or is in functional connection with a scale for weighing an item (15) placed on the panel (3). Finally, the invention relates to a method for determining the weight of an item (15) on an at least approximately horizontal panel (3) of a household appliance (1), in particular on a top panel (3) of a cooking hob. An acceleration of a panel (3) section or of a panel reference point or reference area, in particular a reference point or a reference area on a panel surface (7), is estimated or determined during a displacement or deflection or bending of the panel section or the panel reference point or reference area due to a placing of the item (15) on the panel.

    Abstract: The present invention relates to a method for controlling a first cooking zone (18) and a second cooking zone (20) of an induction cooking hob, wherein each cooking zone (18, 20) is supplied by a corresponding generator (14, 16), and wherein the method comprises the steps of inputting a requested power (P1, P2) for each cooking zone (18, 20), activating a one-zone mode, if the requested power (P1, P2) for one cooking zone (18, 20) is bigger than zero and the requested power (P1, P2) for the other one cooking zone (18, 20) is zero, and activating a two-zones mode, if the requested powers (P1, P2) for both cooking zones (18, 20) are bigger than zero. If the two-zones mode is activated, then an algorithm (48, 50, 52, 54) is selected from a set of algorithms (48, 50, 52, 54) in dependence of the requested powers (P1, P2) for the cooking zones (18, 20).
