Patent ID: 7586065

Claim:
A device for cooking a substance, said device comprising: an elongated member having a first end and a second end, opposed from the first end, for containing the substance; a simmer sensor located near the first end of the elongated member for sending a simmer signal if the simmer sensor senses a decrease in temperature near the first end below a simmer temperature; a heater located at the second end for heating the substance at different power levels; a boiling point sensor to send a boiling point signal to the controller when the substance is boiling; a controller for receiving signals including the simmer signal and sending power level signals to the heater; wherein once the substance is at a boiling temperature, which is higher than the simmer temperature, the simmer sensor senses the temperature at the first end remote from the second end and sends the simmer signal to the controller if the temperature of the substance decreases below the simmer temperature, and, in response to receiving the simmer signal, the controller sends a simmer power level signal to the heater to cause the heater to heat the substance at a simmer power level and wherein once the simmer sensor senses that the temperature at the first end increases above the simmer temperature, the simmer sensor discontinues sending the simmer signal to the controller, and, in response to not receiving the simmer signal, the controller sends a non-simmer power level signal to the heater causing the heater to heat the substance at a non-simmer power level, lower than the simmer power level.
