An electronic tag is attached to a filter cartridge, which includes a filter. In particular, the present invention includes a Prepaid Validation Device for issuing prepaid cards, the PVD having a removable Memory Unit on which Personal Identification Numbers are stored. A data storage stores a plurality of therapy plans generated for a subject by the therapy planner and the predictive plan adaptation module based on at least one planning image of the subject. The ionomer membrane plates are, therefore, more efficient at transferring latent heat than plates constructed of metal or paper. The power-on management system supplies output signals that: control the discharge of the internal supply nodes at the initiation of power-on; force the active mode of the voltage down-converter; and deactivate a fast local voltage reference on completion of power-on. In addition, the inner structures can be filled with an active mass substance.
