An assembly is provided for an aircraft structure. This aircraft structure assembly includes an acoustic panel and a thermal anti-icing system. The acoustic panel includes an exterior surface. The thermal anti-icing system includes a susceptor and a microwave system. The susceptor is configured with the acoustic panel. The microwave system is configured to direct microwaves to the susceptor for melting and/or preventing ice accumulation on the exterior surface.

A heating cooker according to the present disclosure includes a heating chamber, a heating unit, a capturing unit, a control unit, an appearance characteristic analysis unit that analyzes an appearance characteristic of a heated material, an information reading unit that reads heating control information, an information storage unit in which an acceptable range of the heating control information is registered, and an information determination unit that determines whether the heating control information read by the information reading unit is within the acceptable range. When the heating control information read by the information reading unit is within the acceptable range, the control unit executes heating control based on the heating control information read by the information reading unit. When the heating control information read by the information reading unit is not within the acceptable range, the control unit does not execute heating control based on the heating control information read by the information reading unit.

Provided is a device for microwave hyperthermia that may attach a flexible patch on the skin of a user based on a cross-section of a body tissue of the user, for example, a joint and muscle of a leg and an arm and may emit microwaves towards a plurality of points of the body tissue through the patch. The microwaves emitted toward the body tissue may have the same phase and maximum power. Accordingly, a maximum heat generation point may be generated in an area adjacent to the plurality of points. The device for microwave hyperthermia may move the maximum heat generation point by sequentially changing a phase and a direction of each of the microwaves. The device for microwave hyperthermia may uniformly distribute and maintain heat for treating pain and/or infection over the entire cross-section or a partial area. The device for microwave hyperthermia may be portable.

A household appliance includes: a magnetron for generating microwaves during operation; a power supply unit; and a controller for specifying to the power supply unit a power level for the operation of the magnetron. The controller temporarily reduces, in a coexistence mode, the power level specified to the power supply unit for the operation of the magnetron in a manner that reduces or prevents disturbance of communication in a wireless network using beacon frames due to the microwaves generated by the magnetron.

Control electronics may control power amplifier electronics associated with application of RF energy generated using solid state electronic components. The power amplifier electronics may be configured to control application of RF energy in an oven according to a cooking recipe at least in part based on a learning procedure that generates a power cycling between high and low powers when the learning procedure is executed. The control electronics may include processing circuitry configured to employ a thermal stress mitigation technique to control thermal stresses on the power amplifier electronics associated with the power cycling.

A method of determining heating strategies for a cooking appliance (10) includes obtaining geometry dimensions, power values, and frequency values of the cooking appliance (10), selecting a food item (14) and obtaining a food geometry, permittivity value, and initial temperature of the selected food item (14). A heating pattern (28) for heating the selected food item (14) is estimated based on the food geometry, permittivity value, and initial temperature of the selected food item (14) and data indicative of the estimated heating pattern (28) is inputted to an operating control system (21) to achieve the estimated heating strategy.

A microwave heating method and unit for heating an aerosol-forming sample due to microwave absorption by a material of the sample and in particular for thereby releasing by or from said sample upon heating said sample at least one aerosol, in particular in a or as a inhalation, vaporizer and/or smoking product or device, in particular for medical and/or pulmonary drug delivery applications. The microwave heating unit includes (i) a sample holding and exposing unit configured to receive and hold a sample in a holding and exposing space and to expose the sample to a microwave radiation field within said holding and exposing space, (ii) a microwave radiation generating and/or releasing unit configured to release the microwave radiation field to said holding and exposing space, and (iii) an impedance matching unit configured to achieve impedance matching between the holding and exposing space and the microwave radiation field.

A defrosting system includes an RF signal source, an electrode proximate to a cavity within which a load to be defrosted is positioned, and a transmission path between the RF signal source and the electrode. The system also includes power detection circuitry coupled to the transmission path and configured repeatedly to take forward and reflected RF power measurements along the transmission path. A system controller repeatedly determines, based on the forward and reflected RF power measurements, a calculated rate of change, and repeatedly compares the calculated rate of change to a threshold rate of change. When the calculated rate of change compares favorably with the threshold rate of change, the RF signal source continues to provide the RF signal to the electrode until a determination is made that the defrosting operation is completed, at which time the RF signal source ceases to provide the RF signal to the electrode.
