The invention concerns a method for organising the flow of goods for a stock consisting of heterogeneous units arranged closely on top of and beside one another in stacked standardised parallelepiped-shaped containers which are joined into several co-ordinate-forming layers of containers in a vertical framework. In one embodiment, an apparatus includes a first interrupt controller having a first programming model, and emulation logic to emulate a second interrupt controller having a second programming model that is different from the first programming model. The driving unit has a closed air space with a constant internal air pressure. The plurality of second lines is generally arranged orthogonally to the plurality of first lines. With this approach, the thyristor can be rapidly switched between resistance states, which has been found to be particularly useful in high-speed data latching implementations including but not limited to memory cell applications. The fastener is threaded into the first member, the second member, and matches with the seat.
