Abstract: An induction heating system includes an induction heater, a user interface for setting a desired temperature value of induction heater, and a cooking vessel. The cooking vessel is formed of an induction-compatible material and includes a base, an exterior wall, and an interior surface. A control system is configured to receive the desired temperature value of the induction heater, estimate an actual temperature value of the cooking vessel, and compare the estimated temperature value with the desired temperature value. If a difference between the estimated and desired temperature values is outside of a predetermined threshold, the control system adjusts the induction heater until the difference between the estimated and desired temperature values is within the predetermined threshold.

Abstract: A cooking vessel includes a cooking surface and a lower portion positioned below the cooking surface. A first material is disposed within the lower portion and is in thermal proximity to the cooking surface. The first material increases in temperature upon absorption of electromagnetic radiation. A second material is disposed within the lower portion and in thermal proximity to the cooking surface. An electrical current is induced in the second material upon exposure to an electromagnetic field. Both the first material and the second material are configured to heat the cooking surface of the cooking vessel when used in a microwave oven or on an induction cooktop, respectively.

Abstract: A method for estimating a temperature measurement of an item of cookware being heated is provided. The method includes (1) placing a cookware item containing water, on a cooking plate; (2) powering an electric heating circuit with a first power for a first time interval to heat the cookware item as far as the water contained therein boils, wherein said first time interval is determined so as said temperature sensor senses a first steady state temperature value; (3) powering said electric heating circuit with a second power for a second time interval to heat the cookware item to keep boiling the water contained therein, wherein said second time interval is determined so as said temperature sensor attains a second steady state temperature value; and (4) determining, as a function of said first steady state temperature value and of said second steady state temperature value, an induction cooktop gain.
