A driving method and a PDP apparatus of a dot-matrix type PDP, in which a display of high-luminance and high-quality can be obtained when driven by the interlacing method, have been disclosed. A retaining ring actuator is disposed within the retaining ring to control the height of the retaining ring relative to the bottom surface of the wafer carrier. During parsing of the XML document, an event associated with a parser plug-in module may be detected. The controller and second actuator constructed and arranged to exert a compensation force andor torque to compensate a torque caused by the actuation force exerted by the first actuator on the balance mass. A data output may deliver output data indicative of whether the vehicle charge station is publicly accessible based on the determination of such public accessibility by the computer data processing system. In an embodiment, the network includes a storage system for the data about the device is in the controller; a first subsystem for determining that the data should be transferred to the device; and a second subsystem for transferring the data to the device for use.
