A computer-implemented warranty knowledge base construction system and method. The assembly also includes a mounting plate positioned within the sensor housing, outside of the heater shell. The method stochastically assigns threshold values to pixels corresponding to a first element within the multiple line segments of a first level and assigns a same threshold value to a pixel corresponding to a single level to create a first element stochastic fill sequence. The conductive third plate has an electrical length with respect to the proximate edge corresponding to an odd integer multiple of a quarter of a guide wavelength associated with a resonant frequency of the antenna.
