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.
