A method for treating snoring, sleep apnoea and other forms of sleep disordered breathing involves administration to a patient of a therapeutically effective amount of topiramate over an appropriate period of time, such as a period substantially coinciding with the sleep period of a patient. The method begins with coating an alignment layer on the backplane. The membrane filtration results in the formation of a retentate having a reduced level alkali metal relative to the feed solution, and a permeate containing substantially the balance of alkali metal. The retard control can also be replaced by an engine or vehicle speed control to limit the engine or vehicle speed below a predetermined engine or vehicle speed, respectively, irrespective of the throttle position. If the person to contact has plural phone numbers, the control unit controls the communication processing unit to make calls to these phone numbers in parallel.
