Claim of US Patent No. 10,342,074

1. A heating apparatus configured to heat a structure, the heating apparatus comprising:a housing member;
a plurality of heating elements disposed within the housing member;
a plurality of resonant frequency power sources attached to the housing member and coupled with the plurality of heating elements; and
at least one controller configured to:
determine, based on received temperature information associated with the plurality of heating elements, a plurality of resonant frequencies corresponding to the plurality of heating elements; and
dynamically control, for each of the plurality of resonant frequency power sources, a corresponding drive frequency on and off a respective resonant frequency of the plurality of resonant frequencies to thereby meet a desired temperature profile across the structure.
