A process for modifying a polymeric surface, the process comprising; contacting the polymeric surface with a solution comprising at least one ethylenically unsaturated monomer; and exposing the polymeric surface in contact with the solution to ultra-violet light to provide a graft-polymer of the monomer coated on the polymeric surface. In one embodiment, the absorbent article comprises a body, including an exudate impermeable backsheet, and exudate permeable topsheet that is attached to the bottom sheet, and an absorbent core that is positioned between the backsheet and topsheet. The fins and the base may be integral with or attached to each other. If the capacitor discharges at a rate higher or lower than predetermined values after the S1 and S2 disconnect switches are opened, then a fault condition is registered, and the S1 and S2 switches will not be commanded to return to a closed position, thus isolating the fault from both the source and the load. The wiring patterns of such transducers can be configured to reduce interference errors due to wiring patterns thereof.
