The present invention describes a method for the treatment of a neurological condition in a subject which comprises administering to a subject in need thereof a therapeutically effect amount of a compound of the formulaor pharmaceutically acceptable salts, hydrates, or solvates thereof. A battery separator has an ionically conductive separator film having a first functionalized outer surface with a plurality of oxygen atoms providing one to twenty percent of the total atoms present on the surface to provide a greater electrolytic uptake than a non-functionalized film. The supplier and the customer agree on a desired performance level, and the charge to the customer is set at a fixed price plus a variable price based on performance level. In using the present invention, an operator must select an operating mode, either automatic or manual, using a two-position switch. The IO of the second latch is connected to a second input of the tristatable input inverter.
