A cooking control system having a temperature probe and a cooking appliance is described for permitting temperature target cooking of foods. The probe includes a metallic insertable portion with a sheathed tip and a temperature sensor positioned therein, a flexible heat-resistant wire coupled to the temperature sensor, and a jack coupled to the flexible, heat-resistant wire opposite the metallic insertable portion. The cooking appliance includes a heating unit, an housing, a temperature reader, and an alpha-numerical display. In use, the temperature sensor produces a signal in response to a temperature sensed at the sheathed tip and the heat-resistant wire and jack transmit the signal produced by the temperature sensor to the port of the cooking appliance. The temperature reader within the housing is coupled to the port and configured to accept and accurately convert the signal produced by the temperature sensor to a number representing the temperature sensed by the sensor and display the number for the user.

The present invention relates to a microwave powered sensor assembly for microwave ovens. The microwave powered sensor assembly includes a microwave antenna to generate an RF antenna signal in response to microwave radiation at a predetermined excitation frequency. A direct current (dc) power supply circuit of the microwave powered sensor assembly is operatively coupled to the RF antenna signal to extract energy from the RF antenna signal and produce a power supply voltage. A sensor is connected to the power supply voltage and configured to measure a physical or chemical property of a food item under heating in a microwave oven chamber.

A radio frequency heating system includes a radio frequency heating chamber, a fluorescence temperature measuring transmitter, and a central control unit connected to the fluorescence temperature measuring transmitter. A radio frequency heating container is arranged at the bottom of the radio frequency heating chamber. The radio frequency heating container comprises a fluorescent material with temperature-sensitive fluorescent characteristics, which is excitable by excitation light to produce fluorescence. A light path is provided between the radio frequency heating container and the fluorescence temperature measuring transmitter. The fluorescence temperature measuring transmitter includes a light emitting device for generating excitation light and a driving circuit thereof, a photoelectric converter device for receiving fluorescence, and a signal processing and output circuit for processing output signals of the photoelectric converter device.

Several embodiments include a cooking appliance/instrument (e.g., oven). The cooking appliance/instrument can include a cooking chamber, a support tray adapted to hold food in the cooking chamber; and a heating system comprised of at least a heating element. The heating system is adapted to emit waves according to a particular configuration such that the emitted waves is substantially transparent or substantially opaque to the support tray and thus enabling the cooking instrument to select what to heat.

An object of the disclosure is to prevent the sensing accuracy of an exhaust gas sensor from being deteriorated by the effect of electromagnetic waves in an exhaust gas purification system for an internal combustion engine that is configured to apply electromagnetic waves to the exhaust gas purification device provided in an exhaust passage of the internal combustion engine. The disclosure is applied to an exhaust gas purification system for an internal combustion engine including an exhaust gas sensor located within the range of radiation of electromagnetic waves from a radiating device that radiates electromagnetic waves of a specific frequency to an exhaust gas purification device. The system suspends the radiation of electromagnetic waves from the radiating device during a sampling period in which sampling of the output value of the exhaust gas sensor is performed, even when a specific condition for performing the radiation is met.

The present invention relates to a medical preparation container which includes a microwave power sensor assembly. The microwave powered sensor assembly includes a sensor configured to measure a physical property or chemical property of a medical preparation during its heating in a microwave oven. The microwave powered sensor assembly is configured for harvesting energy from a microwave radiation emitted by the microwave oven and energize the sensor by the harvested microwave energy.

A microwave oven is described herein. In some instances, such a microwave oven may include a housing; a rotating turntable assembly disposed in a cooking cavity of the housing; a probe powered by the turntable assembly, where the probe is configured to measure an environmental condition during a cooking cycle and where the probe is configured to transmit a signal regarding the environmental condition; and a controller disposed in the housing and configured to receive the signal regarding the environmental condition from the probe. A method of operating a microwave oven for sous vide cooking is also disclosed.

A microwave oven comprising a cavity in which a material can be placed for heating and a magnetron for generating a microwave. The microwave oven further comprises an electromagnetic element adapted to interact with microwaves into the cavity and a control unit that provides a control signal to the electromagnetic element for modifying an impedance of the electromagnetic element during time of heating.

Several embodiments include a cooking appliance. The cooking appliance can include one or more heating elements; a cooking chamber; and a camera attached to the interior of the chamber. In some embodiments, the cooking chamber prevents any visible light from escaping the chamber (e.g., the cooking chamber is windowless). In some embodiments, the heating elements are controlled by a computing device in the cooking appliance. In some embodiments, the output of the camera is used to adjust heating pattern of the heating elements.

A solid-state radio frequency (SSRF) water heating apparatus is disclosed. In embodiments, the SSRF water heater includes a water tank, SSRF generator array and RF sensors enclosed within an RF-shielded cage. The SSRF array synthesizes RF signals in the microwave range and transmits the RF energy through the water tank, exciting and heating the water molecules without direct contact. The RF sensors at the opposite end of the tank sense residual RF energy not absorbed by the water. Control processors regulate the generation and transmission of the RF energy based on the sensed residual energy. The heated water and/or generated steam is piped to hot water dispensers, beverage makers, or steam ovens.
