Art instrument having a self-contained reservoir for storing and dispensing application liquid includes a reservoir body for containing the application liquid and a dispensing assembly that dispenses the application liquid from the reservoir. Metal ions are deposited on the exposed first surface and on the exposed second layer by applying a first voltage between the substrate and an anode in the presence of an electrolytic bath, and metal ions are removed from the exposed first surface by applying a second voltage between the substrate and the anode in the presence of the electrolytic bath. The light source provides light for illuminating the ROI, displaying an image, providing a therapy, andor performing other functions. The antivirus software executes upon the computer and transfers results to the mobile telephone. When the compared results concur, the controlling software performs actions associated with the concurring results by executing microprocessor-based software. The method comprises the steps of: an MTC GateWay acquiring the information of the MTC UE which currently requests to attach to a network or has attached to a network from a mobility management network element; the MTC GW sending the information of the MTC UE acquired from the mobility management network element to an MTC Server.
