A drill string is equipped with a downhole assembly having an instrumented sub and a drill bit. Provided by the invention are the seeds, plants and derivatives of the soybean variety 01046197. These transformations are dependent on the techniques used in generating the power optimized design from the golden design, and may be generically described in a transformation language that provides the necessary constructs to specify an entire set of valid structural modifications. In other embodiments, the wheels are pivoted through 90 to the stowed state thereof. A second group frame includes an opening portion, a prism retaining frame that is arranged in a more inner position than the opening portion and in which the prism is contained, and a plurality of adhesive pockets arranged on an area around the prism retaining frame and being open to the side of the opening portion. Characters and commands assigned to the rows above and below the home row are engaged by sliding the fingers over the capacitance-responsive surfaces adjacent to the home row.
