This invention consists of a virtual air gap\u2014VAG system developed in order to provide Internet and computer security. The processor may acquire the first unique identifier from the first component and store the first unique identifier in the one time programming section during the first time initialization. Upon receipt of the page request, each RBS decapsulates the received message, extracts the routing area information, derives the cell list to be paged from the RBS resident routing area-cell mapping table and performs the actual radio page broadcast over the destination cells. Zoning is dynamically controlled from a workstation operated by a System Administrator entering meta-zoning instructions which are used to automatically program the zoning of the SAN Switch for legitimate physical devices. In one embodiment, the camera-based system can be used in conjunction with a training aid that is attached to a basketball rim. The combination of disposable tubing, flexible-wall containers, aseptic connectors, manifold, controller, and conductivity sensors provides an aseptic environment while avoiding or reducing cleaning and quality assurance procedures.
