A data analyzerclassifier comprises using a preprocessing step, and energy minimization step, and a postprocessing step to analyzeclassify data. The talking electronic scale determines the weight of a particular person in response to a specific user input. These estimates are insensitive to anistropy and dip, undesirable complications of directional measurements. A heat plate grinder on which a grinding apparatus for grinding the heat plate is mounted is spaced a predetermined distance from the die pressing member. The interlevel dielectric layer disposed on the upper surface overlies the gate trench and the source region, and a metal layer in electrical contact with the source and body regions overlies the upper surface and interlevel dielectric layer.
