An articulating downspout assembly for a downspout system of a building has an elbow component and an end component each having an integrated or integral configuration that cooperatively join with each other to form a hinge. A program stored in the non-volatile memory contains an instruction for jumping to a subprogram in an auxiliary memory. Further, the electric machine includes a modulator outer rotor that is concentric and is located proximate to the outer stator. The selected different superimposed data information may comprise a band identifier in the superimposed data information of one or more of the servo bands. The method finds particular implementation in the rebalancing of tree data structures.
