An apparatus for rapidly heating a cooktop is provided. The apparatus comprises a radiant heating element positioned proximate to the cooktop. A controller is provided and is connected to the radiant heating element. The controller includes a fast heat-up circuit selectively coupled to the radiant heating element. A look-up table is selectively coupled to the fast heat-up circuit. The look-up table comprises a plurality of user power levels. Each of the plurality of user power levels is correlated to a respective user-selected temperature. The apparatus further comprises a user power input device connected to the controller. The user power input device also allows selection of at least a first of the plurality of user power levels wherein the first power level corresponds to a first respective user selected temperature in the look-up table. A temperature sensor is connected to the controller for measuring a temperature of the cooktop.

The temperature of a cooktop is controlled such that a maximum temperature of a cooktop reaches about a predetermined maximum temperature. The temperature is controlled by controlling power supplied to a radiant heating element positioned below the cooktop. The radiant heating element heats the cooktop. A user power input device allows a user to select a user power level corresponding to a desired temperature range for heating the cooktop. A temperature sensor is supplied that senses the temperature of the cooktop. A thermal limiter controller is connected to the radiant heating element, the user power input device and the temperature sensor. The thermal limiter controller determines a thermal limiting power level. The thermal limiter controller applies the smaller of the user power level and the thermal limiter power level to the radiant heating element. An anti-wind up controller is connected to the thermal limiter controller and tracks the thermal limiter power level to the user power level whereby a maximum temperature of the cooktop reaches about the predetermined maximum temperature.

A system for producing a process advisor application uses a process mapping program, a compiler and a program such as a Java servlet to produce a process advisor application. The process mapping program is used to create a decision tree, and the compiler compiles the decision tree into a data file. The data file is then converted into one or more computer viewable documents, such as web pages.
