The present invention relates to a retaining and release mechanism for the magazines of automatic andor semi-automatic firearms, in particular to a type of magazine which is provided with a lateral securing slot. The gateway module has redundant microcontrollers operably connected to the VMC for selectively controlling supply of electrical power to a plurality of separate electrical loads. The IPW capacitor is provided in the otherwise unused space below the control gate capacitor by a IPW that is separated from the controlfloating gates by a dielectric layer and is electrically connected to the control gate. The coherent mass is advanced out of the die and cooled to form the filter element. Line qualification is determined based on an average of the inversely randomized measurements.
