CONTROLLING HEATING OF A SURFACE

摘要

The heating of a surface is controlled by: monitoring the temperature of a plurality of zones of the surface to output at least one temperature reading of each of the plurality of zones. The temperature readings are modulated in response to a pattern arranged across a portion of the plurality of zones. The energy delivered to each of the plurality of zones is controlled based on the modulated temperature readings to maintain a substantially homogeneous temperature distribution across the surface.
