  • Patent number: 7214914
    Abstract: A method of operating a microwave oven to determine the correct cooking time for a food item placed within the oven. A food package having a thermochromic element which changes color over a predetermined temperature range is placed in the microwave oven. Microwave energy is supplied into the oven. The food package is rotated within the oven cavity and the color of the thermochromic element is monitored as it rotates past an opto-electronic device or detector capable of detecting the color changes of the thermochromic element such that a plurality of signal pulses are generated having a value corresponding to the color of the element. The supply of microwave energy into the oven is terminated when the rate of change between successive pulses decrease to a predetermined value.

  • Patent number: 7216049
    Abstract: One embodiment is a method of calibrating current offsets from a direct current bus current circuit adapted to control a motor including the steps of initializing the direct current bus current circuit, disengaging pulse width modulated signals to the motor, sampling current values at a predetermined sampling rate, averaging the current values over a predetermined number of samples to establish an offset value, and calculating a calibration value that will nullify the offset value in any subsequent processing of current samples. Another embodiment, a method of filtering inaccurate data from a sequential calculation of power values based on repeatedly sampled voltage and current including the steps of establishing a moving window of a predetermined number of power values, calculating an average power over a sequence comprising the predetermined number of power values, calculating an error value for each time, and comparing each error value to a preset value.

  • Patent number: 7210307
    Abstract: A refrigerator having a freezer compartment having an ice maker disposed within the freezer compartment for forming ice pieces and an ice storage bin removably mounted to freezer compartment door below the ice maker having an open top receptacle for receiving ice pieces from the ice maker. The ice storage bin has a movable lid assembly including a frame removably mounted to the top of the ice storage bin and two lid members mounted to the frame. At least one lid member is pivotally mounted to the frame to close the receptacle when pivoted to a generally horizontal position and to open the receptacle when pivoted to a generally vertical position. The pivotal lid member is biased to the generally horizontal position.

  • Patent number: 7210601
    Abstract: A variable flow rate water dispenser mounted on a refrigerator door is provided that can dispense water at user selected flow rates. The water dispenser includes a nozzle for dispensing water from a dispenser housing on a refrigerator door and a user adjustable flow control. The user adjustable flow control can include a variable flow rate water valve or a plurality of water valves that can have different flow rates and can be operated separately or in combination to provide different flow rates. The user adjustable flow control can alternately include a variable flow pump for controlling flow of water to the nozzle at a user selected flow rate. The refrigerator can include a reservoir inside or outside the refrigerator. The reservoir can be connected to a source of water and automatically filled or can be manually filled. The nozzle can include a flow straightener or aerator to minimize splashing.
