A fast pattern processor having an internal function bus and an external function bus. The provided hierarchical structure graph includes nodes, a specified number of levels, with at least one node located in each level, and edges connecting pairs of predetermined nodes of different levels and defining, for each pair of nodes, a lower father node and an upper son node. The device also includes means for measuring the thickness of each flat object pressed against the destacking plate. The method subsequently transferring to a second one of the pair of storage volumes at the remote location the most recent pair of the stored sets of changes in the in the sequence of data stored at the source at a time prior to such subsequent transfer. At regular intervals the processor will process sensor readings, determine the volume of gas within the buoyancy chamber, and determine depth and ascent or descent rate. The kit comprises a container holding a solid composition therein, the solid composition including a basic salt and a transition metal.
