The present invention provides a bank storage unit that may be supported andor mounted to a bank holder to allow a user to store the bank storage unit to any vertical surface. An example weapons safety system in which the enabling of a weapon to shoot is controlled by means of an exchange of identification between the weapon and an enabling apparatus. An NSIS entity handles an NSIS protocol stack at the request of the NAPI block. Alternatively, the material of the substrate may be, for example, Cu alloy, stainless steel, Nb alloy, or V alloy. Such offset positioning may be based on the airflow paths and cooling requirements at selected high-temperature operating conditions.
