Novel data structures, methods and apparatus for finding a full match between a search pattern and a pattern stored in a leaf of the search tree. A first area has an array of menu items. The relative sliding becomes more constrained as the tibial meniscal component moves toward the sides of the base plate. The test method is preferably applicable in communication devices. The cap is so configured as to have a second movable length which is smaller than the first movable length, during the movement between the first position and the second position. Particularly, the invention introduces several access priority methodologies including: random chip delay access priority ; random backoff based access priority ; variable logical channel based access priority ; UMTS-specific variable logical channel based access priority ; probability based access priority ; and retransmission based access priority.
