Intraocular lens delivery devices and methods of use. A general configuration will be broken down into a hierarchy of subdesigns by a designer of an artifact type. The modules may be one or more of an automatic speech recognition, natural language understanding, dialog management and text-to-speech module or engine. Additionally, the BIST circuit is variable, as the resolution of the circuit changes from chip to chip, and digital, as it is implemented with standard digital logic elements. Thus, the invention intends to improve the quality of products through precise dryer control, as well as reduce the time required for grade change, by precisely predicting the web’s initial moisture percentage at the dryer inlet after grade change and precisely and quickly controlling dryer steam pressure during grade change.
