A method in a data processing system for generating trie structures, comprised of the following steps: The method identifies mappings, which have elements, in a map file. When a cylinder member is being held, in a specific direction of rotation about the axis of the mechanism, by a cylinder holding mechanism, an RFID chip and an RFID reader become communicable, making the piston drive mechanism operable. The power for driving the brush driving motor is controlled to provide oscillatory motion subject to operator controlled frequency, amplitude and oscillatory wave shape.
