An interbody device for the fixation and support of adjacent bone bodies includes a body for implantation at a location between the two vertebrae and one or more protrusions extending from the body. The apparatus incorporates multiple storage components, with each storage component configured to store descriptors of data having one of multiple priorities. Each of the plurality of scaling algorithms provides a unique data-pruning pattern for processing DCT data. The coincidence detection circuit detects coincidence or non-coincidence by comparing the output from the sampling circuit with an expected value for the output from the memory. The final cross-correlation value is input to a suitable tracking means to increase the level of accuracy and case in recognizing and tracking a potential target. A radio base station PhNB#10 according to the present invention is configured to manage a cell #10 which is formed by linking multiple small cells and includes an allocation unit 11 configured to allocate a same C-RNTIph to multiple mobile stations UE#1UE#3 which are separated by at least a predetermined distance in the cell #10.
