A method and apparatus for splitting an asynchronous signal are provided. An approach is described for assessing inconsistency in the activity of an entity, as a way of detecting fraud and abuse, using service-code information available on each transaction. The rechargeable battery comprises an electrode assembly that has first electrode plate, a second electrode plate, and a separator for insulating the electrode plates from each other, all of which are wound together. There is a period of the order to magnitude of one millisecond between the supplying of a control signal to the positioning device at a first point in time based upon which the read andor write head has to be positioned and the actual start of the movement of the read andor write head. The learning is continuous and provides for autonomic evolvement of the system in which reliance on manual input from a user is lessened.
