A USB cable includes two USB connectors and a plurality of cable lines. Then, a sparsity-based support estimation is applied to the input signals according to a reverberation model to produce estimates of the source signals and locations of a set of sources emitting the source signals. Incorporation of this rim into a high stress and strain usage environment, such as a flywheel system, allows the rim to be spun at high speeds in order to generate high levels of kinetic energy while beneficially managing the amount of strain and radial stresses generated within the rim, and, in turn, minimizing or at least controlling the formation and propagation of cracks within the rim.
