Patent ID: 7304274

Claim:
A power regulation module to provide power to one or more heating elements, the module comprising: a circuit board that includes: a control circuit configured to control the power applied from one or more electromechanical devices to the one or more heating elements; and a non-transformer based power supply circuit configured to provide DC current to at least one of: the control circuit, and the one or more electromechanical devices; a switch having a plurality of positions that are each associated with a different power setting to control the control circuit, wherein the switch is mechanically connected to the circuit board; and a housing for receiving the circuit board, the housing includes an opening through which a user-controlled actuator is mechanically connected to the switch, the actuator is configured to be placed in one of a plurality of positions corresponding to user-provided input; wherein the control circuit includes logic to generate an output signal having a duty cycle based on user-provided input, the logic including: an input to receive a profile selection signal, and a data memory for profiles, each profile defining an association between input signals and output signals, and in which the logic uses the profile selection signal to select one of the profiles, the input signals being the same for each profile; and wherein the one or more electromechanical devices are connected to apply power to the one or more heating elements based on the output signals generated by the logic.
