Abstract
A cook-top (10) includes a plurality of heating elements (11a, 12a) which are activated by function controls. The heating elements are covered by a plate (15) which are fixedly connected to strain-guage modules (30) which detect the forces exerted on the plate as a result of loads placed on the heating elements. By computing the center of gravity of the forces, controls (70, 75, 76) identify a heating element whose load has varied and influence its electric power supply. The power supply may then be turned off, reduced or controlled. The function controls may be pressure-sensitive touch controls.
