Claim 15:
16. A method for repelling dust from an article, the method comprising:
generating time-varying voltages of different phases;
communicating time-varying voltages of different phases at 120 degrees out-of-phase with one another to a plurality of conductive-fibers arranged between a front surface and a back surface of an outer material of a covering, wherein the time-varying voltages of different phases are configured to cause the conductive-fibers to repel and remove dust from the front surface of the outer material, wherein the time-varying voltages of different phases include a first output voltage, a second output voltage, and a third output voltage, and the first output voltage is 120 degrees out of phase with the second voltage, the second voltage is 120 degrees out of phase with the third output voltage, and the third output voltage is 120 degrees out of phase with the first output voltage, wherein the time-varying voltages of different phases are applied to adjacent conductive-fibers such that the first output voltage, the second output voltage, and the third output voltage are respectively coupled one of every third adjacent conductive-fiber of the plurality of conductive-fibers; and
attaching the covering to the article via a fastening material arranged on a back surface of the outer material that facilitates releasably attaching the covering to the article.
