A paneling system is provided herein that concerns interconnecting panels with opposite connecting sides of substantially tongue in groove joint couplings and opposing adjacent connecting sides that are of substantially hook-joint coupling. A free-zone channel allows the ball bearings to roll freely in the assembly as they follow the motion of the ball and shaft. A vacuum is applied through an annular passage defined between the tubular body and the rotatable element. The first arm has a first inner end and an opposed first outer end, and the second arm has a second inner end an opposed second outer end. The disclosed approach banks on the reconfigurable variable length FIR filter architectures.
