The present invention relates to a means, system and method for controlling the storage space required by a storage means which contains information items associated with an information transfer application. The low conductivity buffer may also contain a zwitterion. The first face and the second face cooperate to define a tapering profile terminating in a cutting edge. A controller analyzes the sensed parameter to detect whether the sensed parameter is within a range indicating the presence of drowsiness. The switching circuit has a control terminal receiving the third control signal, a first terminal connected with the output terminal of the charge pump circuit, and a second terminal connected with a reservoir capacitor. The device comprises a coiling device with a coiling mandrel for winding the metal strip to form a coil on the coiling mandrel and a coil stripper car with supports for receiving the coil from the coiling mandrel and removing the coil from the coiling device.
