A two piece, two-stage, rechargeable, reusable, reduced-energy mechanically operating cartridge is provided for launching a bullet of various compositions from a dedicated or modified firearm. The electromagnetic field may be produced by a primary coil, which inductively couples with one or more secondary coils located within a portable device. This information is used by a segment on the ground to make up and update a look-up table between identifiers of the access network and IP addresses of the aircraft. The database tables include information in performing marketing processes and applications. In an embodiment, the method includes encompassing a lower sidewall of the third portion with the insulative layer. To protect the dome switch from damage due to contaminants, the terminal can be integrated within a volume of the circuit board such that it is not exposed to the environment of the dome switch.
