Abstract
An oven may include a cooking chamber configured to receive a food product, a radio frequency (RF) heating system configured to provide RF energy into the cooking chamber using solid state electronic components to heat the food product, and a context awareness engine. The context awareness engine may include processing circuitry configured to receive RF signature data (including measurements of at least forward power and reflected power) associated with provision of RF energy into the cooking chamber, and to correlate an RF signature with a phenomenon observed with respect to the food product to define a signature profile for the phenomenon observed.
Claims18
An oven comprising:
- a cooking chamber configured to receive a food product;
- and
- a radio frequency (RF) heating system configured to provide RF energy into the cooking chamber using solid state electronic components to heat the food product;
- and
- a context awareness engine comprising processing circuitry configured to:
- receive RF signature data associated with provision of RF energy into the cooking chamber, the RF signature data including measurements of at least forward power (Pfwd) and reflected power (Pref1),
- correlate an RF signature with a phenomenon observed with respect to the food product to define a signature profile for the phenomenon observed, and
- initiate a change in air flow into the cooking chamber based on the signature profile.
An oven comprising:
- a cooking chamber configured to receive a food product;
- and
- a radio frequency (RF) heating system configured to provide RF energy into the cooking chamber using solid state electronic components to heat the food product;
- and
- a context awareness engine comprising processing circuitry configured to:
- receive RF signature data associated with provision of RF energy into the cooking chamber, the RF signature data including measurements of at least forward power (Pfwd) and reflected power (Pref1), and
- correlate an RF signature with a phenomenon observed with respect to the food product to define a signature profile for the phenomenon observed,
- wherein the processing circuitry is further configured to:
- receive current RF signature data responsive to a cooking operation being performed on the food product in the cooking chamber;
- perform a comparison of the current RF signature data to a library of signature profiles;
- and
- classify context information based on the comparison
- by determining a temperature of each component of a multi-component instance of the food product.
A method of operating an oven having a cooking chamber configured to receive a food product, the oven having a radio frequency (RF) heating system configured to provide RF energy into the cooking chamber using solid state electronic components to heat the food product, the method comprising:
- receiving current RF signature data responsive to a cooking operation being performed on the food product in the cooking chamber;
- performing a comparison of the current RF signature data to a library of signature profiles;
- classifying context information based on the comparison, and
- performing a function execution associated with the context information classified,
- wherein performing the function execution comprises initiating a change in air flow into the cooking chamber.
