A method and apparatus for selectively filtering signals on a digital subscriber line so as to prevent interference resulting from a telephone instrument switching between its on-hook and off-hook states. Each of the first pixels and the second pixels includes pixel electrode and each pixel electrode includes a first sub-pixel electrode and a second sub-pixel electrode. The tackiness between the adhesive material and the base member is lower than the tackiness between the adhesive material and the substrate. The nebulizer mechanism comprises a nebulizer port, which rotates 90 degrees in either direction to allow the present invention to be used in various angles. The items are sorted into sharply defined groups that are transversely staggered with respect to one another.
