Abstract

The present disclosure relates to an apparatus for processing objects with RF energy. The apparatus may include a display for displaying to a user an image of an object to be processed, the image including at least a first portion and a second portion of the object. The apparatus may also include an input unit and at least one processor configured to: receive information based on input provided to the input unit; and generate, based on the received information, processing information for use in processing the object to achieve a first processing result in the first portion of the object and a second processing result in the second portion of the object.

Claims

1. An apparatus for processing objects, placed in a cavity, with radiofrequency (RF) energy that is resonant in the cavity, the apparatus comprising:

a display for displaying to a user an image of at least a first portion and a second portion of an object to be processed in the cavity;

an input unit; and

at least one processor configured to;

receive information based on input provided to the input unit; and

cause, based on the received information, application of RF energy resonant in the cavity to the object such that a first processing result is achieved in the first portion of the object and a second processing result is achieved in the second portion of the object;

cause application of a plurality of electromagnetic field patterns to the object in the cavity;

determine an amount of power dissipated in the object for each of the plurality of electromagnetic field patterns;

determine one or more values indicative of energy absorption based on the amount of power dissipated in the object for each of the plurality of electromagnetic field patterns.

2. The apparatus according to claim 1, further comprising a source of RF energy.

3. The apparatus according to claim 1, wherein the at least one processor is configured to generate the image based on electromagnetic feedback providing the one or more values indicative of energy absorption in the object.

4. The apparatus according to claim 1, further including one or more infrared (IR) cameras configured to generate the image of the object to be processed.

5. The apparatus according to claim 1, wherein an image is generated of at least the first portion of the object and the second portion of the object to be processed.

6. The apparatus according to claim 1, wherein the at least one processor is configured to determine a weight associated with the one or more electromagnetic field patterns.

7. A method of processing an object in a cavity using radiofrequency (RF) energy resonant in the cavity, the method comprising:

displaying to a user an image showing various portions of the object in the cavity; and

receiving information relating to processing instructions from the user,

wherein the information relating to processing instructions indicates that a first portion of the object shown in the image is to be processed differently from a second portion of the object; and

applying RF energy to the cavity based on the information;

applying a plurality of electromagnetic field patterns to the object in the cavity;

determining an amount of power dissipated in the object for each of the plurality of electromagnetic field patterns; and

determining the one or more values indicative of energy absorption based on the amount of power dissipated in the object for each of the plurality of electromagnetic field patterns.

8. The method according to claim 7, wherein the image comprises at least one of:

an optical image, generated based on visual light received from the cavity;

a graphical image, generated based on the one or more values indicative of energy absorption in the object;

or

a temperature profile, associating differing portions of the object in the cavity with different temperatures.

9. The method according to claim 8, wherein the one or more values indicative of energy absorption of the object provide a spatial absorption value.

10. The method according to claim 7, wherein the information relating to processing instructions includes at least one of:

a target amount of energy to be dissipated in at least a portion of the object,

a target temperature profile of at least a portion of the object,

a desired degree of doneness of at least a portion of the object, or

a number of cooking units to be applied to at least a portion of the object.

11. The method according to claim 7, further comprising correlating between locations associated with the object in the image and locations associated with the object in the cavity.
