An optical input andor control de andor actuating variable functions of, for examp device, the optical input andor control device ha radiation from a diode laser is converged. Segments of the polylines are generated. The volume-containing element is fluid-tight but for communication with the fluid-delivery and a filling port. The CPNS device stores the terminal information, performs user authentication by decrypting the encrypted terminal information in response to the authentication request, generates an authentication key for the CPNS when a user is authenticated, encrypts the generated authentication key using the password, and transmits the encrypted authentication key to the user terminal through the gateway.
