Abstract: A system for determining the status of a food item using time-temperature data. The system includes a method comprising, sensing a number of temperatures associated with a food item, comparing data related to the sensed temperatures with predetermined temperature data, determining the status of the food item based on the comparison, and causing a predetermined action based on the status of the food item. The method may further involve inputting user information corresponding to the food item, which may include type of food, or the desired level of doneness. The system also includes an apparatus for determining the status of a food item. This apparatus may include a sensor for sensing a plurality of temperatures, a means for determining the status of the food item based on the plurality of temperatures, and an indicator for indicating the status of the food item. The determining means may include a microprocessor. The apparatus may further, include a control sensor.

Abstract: A device that heats food quickly by using more than one power level during a heating cycle, and a method of toasting including the step of heating a food item at more than one power level during a toasting cycle.

Abstract: A method and apparatus for a cooking appliance having a built-in smoke detector is disclosed. The disclosed apparatus includes a housing with a heating cavity, a door, a heating element, a controller, and a detection module. The detection module includes an energy source directing energy toward a first direction, and in communication with the controller, a detector unit receiving energy from a second direction substantially perpendicular to the first direction, and in communication with the controller, and an aperture for allowing entrance of air into the detection module from the cooking appliance, wherein the detector unit detects a level of smoke in the air from the cavity of the cooking appliance based on an amount of energy scattered from the first direction toward the second direction, and an alarm condition is identified based on the level of smoke.

Abstract: The present invention relates to a temperature compensated timer for a heating appliance that heats a food item during a heating cycle. The timer includes a coil having first and second terminals and presenting a resistance between the terminals that is a function of temperature changes of the coil. A timing circuit is coupled to the first and second terminals of the coil. The timing circuit operates to drive a current through the coil to maintain a heating cycle and to generate a delay signal a delay time after the heating cycle is initiated. The delay time has a value that is a function of the resistance of the coil. The delay signal is operable to remove the current from the coil to terminate the heating cycle.
