Patent ID: 11883832
Assignee: THE BOEING COMPANY
Field: Chemical engineering (Chemistry)
Classification: CPC B  D | IPC B  D

Claim 14:
15. A covering comprising:
an outer material having a front surface and a back surface;
a plurality of conductive-fibers disposed between the front surface and the back surface, wherein the plurality of conductive-fibers are configured to receive a voltage that causes the conductive-fibers to repel dust from the front surface of the outer material;
one or more button-snaps coupled to the outer material that facilitate releasably attaching the outer material to an article;
signal conditioning circuitry to generate the voltage, wherein the signal conditioning circuitry includes outputs that generate time-varying voltages of different phases, wherein the voltages of different phases are applied to adjacent conductive-fibers by the signal conditioning circuitry such that a first voltage output is coupled to a first set of conductive fibers and a second different voltage output is coupled to a second set of conducive fibers, wherein the plurality of conductive-fibers are arranged in different dust repelling groups and wherein the signal conditioning circuitry is configured to selectively apply voltage to the different dust repelling groups to selectively repel dust from different regions of the outer material; and
a user interface in communication with the signal conditioning circuitry that facilitates specification of one or more dust repelling groups of conductive-fibers to which voltage is to be applied.
