Combustion gas cartridge for a gas internal combustion fastening device, comprising an external casing over which is crimped the edge of an internal cup beyond which an outlet end projects. The processes are conducted at n or m spatially separate locations for the n or m mixtures, respectively. The first system sends the user’s ID information associated with the second system to the second system, which may allow the user to automatically log on upon successful user ID verification. In one embodiment, two sleeves are employed. P-type field effect transistor gate cavities are protected while N work function metals are deposited in N-type field effect transistor gate cavities.
