摘要： A system includes a core temperature probe and a microwave cooking device. The core temperature probe includes a temperature sensor to determine a temperature information, a coaxial line including a lambda/4 line resonance element adjusted to a microwave frequency, and a signal transmission antenna connected to the temperature sensor via the coaxial line and adapted to emit the temperature information at a signal transmission frequency that differs from the microwave frequency. The system is hereby constructed to transmit a signal at the signal transmission frequency wirelessly between the signal transmission antenna of the core temperature probe and a signal transmission antenna of the microwave cooking appliance.

摘要： A system includes a radio frequency (RF) signal source configured to supply an RF signal. An electrode is coupled to the RF signal source and a transmission path is between the RF signal source and the electrode. The transmission path is configured to convey the RF signal from the RF signal source to the electrode to cause the electrode to radiate RF electromagnetic energy into a cavity. Power detection circuitry is coupled to the transmission path and configured to repeatedly measure RF power values including at least one of forward RF power values and reflected RF power values along the transmission path. A controller is configured to determine that a load in the cavity is a low-loss load based on a rate of change of the RF power values, and cause the RF signal source to supply the RF signal with the one or more desired signal parameters.

摘要： The invention relates to a method and apparatus for determining a size information of food ingredients. The method comprises a step of applying (110) to the food ingredients an electrical field having a given radio frequency, the electrical field being generated by a source positioned in close proximity to the food ingredients, a first step of measuring (120) a ratio between the energy of the electrical field reflected from the food ingredients, and the energy of the electrical field generated by said source and applied to the food ingredients. The method also comprises a first step of determining (130), based on said ratio, an average thickness of the food ingredients along the direction of the electrical field applied to the food ingredients. The method also comprises a second step of measuring (140), for a plurality of distances between the source of the electrical field and the food ingredients, the ratio (R2) between the energy of the electrical field reflected from the food ingredients, and the energy of the electrical field applied to the food ingredients. The method further comprises a step of identifying (150) a relatively sudden change in the amplitude of the ratios measured by said second step of measuring (140) and a step of deriving (160) the corresponding distance between the source of the electrical field and the food ingredients for which said relatively sudden change occurred. The method also comprises a second step of determining (170), based on said corresponding distance and the divergent angle of the electrical field irradiating at said corresponding distance, an average diameter of the food ingredients in a plane perpendicular to the direction of the electrical field applied to the food ingredients. This invention results in a more convenient, robust and accurate way to determine the average thickness of the food ingredients.

摘要： The invention relates to a method (100) and apparatus for controlling the heating of food ingredients. The method comprises the step of measuring (110) the spectrum of energy absorption of the food ingredients in a given range of radio frequencies. The method also comprises the step of identifying (120), in said given range of radio frequencies, the radio frequency for which the food ingredients have the maximum energy absorption. The method also comprises the step of applying (130) an electrical field to the food ingredients, said electrical field having a radio frequency corresponding to said radio frequency for which the food ingredients have the maximum energy absorption. The step of measuring (110) comprises, for a plurality of selected radio frequencies in said given range of radio frequencies, the steps of: applying an electrical field on the food ingredients having a radio frequency corresponding to a given selected radio frequency in said plurality of selected radio frequencies; and, measuring the ratio between the energy of the radio frequency electrical field reflected or absorbed from the food ingredients, and the energy of the radio frequency electrical field applied to the food ingredients. The plurality of selected radio frequencies are selected from said given range of radio frequencies by the steps of: for each of said given range of radio frequencies, obtaining a penetration depth of an electrical field having a radio frequency corresponding to the given radio frequency into the food ingredients, and including the given radio frequency into the plurality of selected radio frequencies if the penetration depth of the electrical field having radio frequency corresponding to the given radio frequency is equal to or larger than the thickness of the food ingredients in the direction of the electrical field applied to the food ingredients. This invention allows reducing the heating time of food ingredients.

摘要： The present invention relates to a method and apparatus for controlling a cooking process of food. The method comprises a step of emitting (101) a plurality of radio frequency signals into the food non invasively. The method also comprises a step of receiving (105) a plurality of reflection signals or transmission signals of the radio frequency signals from the food, wherein the reflection signals is a part of the radio frequency signals that reflect from the food, and the transmission signals is a part of the radio frequency signals that transmit through the food. The method also comprises a step of obtaining (110) a protein status, wherein the protein status is the extent of protein denaturation, in the food in the course of heating the food based on the plurality of radio frequency signals and the plurality of reflection signals or transmission signals. The method also comprises a step of determining (120) a doneness level of the food based on the protein status, and a step of controlling (130) the cooking process of the food based on the determined doneness level. Using the protein denaturation provides a more direct and precise information of the status of food based on established relation between the doneness level and the protein denaturation extent.
