A fluid monitoring apparatus and method is disclosed for use in an underground utility vault. The expandable intervertebral implant includes a pair of outer sleeve portions and an inner core disposed between the outer sleeve portions. A bank prediction field is associated with each memory access operation. The central hole has a round shape, while the exterior has a triangular shape. This method makes it possible to obtain reinforced processing capacities by enriching the capacities of the first processing with the capacities of the other processing without calling into question the logical and physical interfaces of the first processing.
