Abstract
A temperature-regulating unit includes a base, a resonant tank, and a controller. The base is configured to support a pan. The resonant tank includes a coil and a capacitor. The resonant tank has a resonant frequency that is affected by a material of the pan and a temperature of the pan. The controller is configured to receive a temperature setting, monitor the resonant frequency, determine the material of the pan based on the resonant frequency, determine the temperature of the pan based on the resonant frequency, and adaptively control a thermal element based on the temperature of the pan, the material of the pan, and the temperature setting.
