Various embodiments of a method, system and article of manufacture provide a version number. A stapling flange and a flashing flange extend widthwise from the top and bottom cover strips respectively along a first side of the insulation strip and are sealed to each other along a bond line near the first side. A water chamber generates water vapor at a preselected temperature and is capable of controlling the temperature of water in the water chamber in a stepwise manner. Reversing the illumination and observation directions allows subtraction of the two images and measurement of the magnetization in-plane. a frequency range extending from 3. The methods and systems may be used for motor or actuator applications where accurate, high resolution torques may be need over a relatively wide range.
