An apparatus for cleaning a flat panel display and a roll brush used therein are provided. The rotor has two discs that are axially spaced apart to form an armature airgap. The attachment points are substantially equidistantly spaced apart along a line of substantially equal latitude. The method also includes presenting the application and the second information based upon the presentational information, and storing on the client computer an interactive link for selectively re-establishing the second communication connection to the application server for retrieving the first information and presenting the application and the second information on an as-needed basis. By the relaxed constraint, a compiler and a smart assembler have more choices to schedule instructions in a program, potentially increasing program performance.
