The thermal processing device includes a stage, a continuous wave electromagnetic radiation source, a series of lenses, a translation mechanism, a detection module, a three-dimensional auto-focus, and a computer system. Silica particles disposed within the gel composition and are configured to at least partially dissolve in an alkaline environment. Start point block pixel data and end point block pixel data are set based on a change rate of luminance values of adjacent block pixel data. The limit swing generator includes at least one voltage generator to control the voltage level of the drive signal such that the drive signal tracks a parametric variable of the output switches. The method may include producing a mixture through a second part of the formation. The method further includes recognizing the voice signal by matching the voice signal to an entry of the speech recognition grammar and providing a directory listing to the caller based on the entry of the speech recognition grammar.
