Various embodiments of the present invention provide systems and methods for treating a proximal humeral fracture. A base signal is recursively decomposed for a desired number of pyramid levels. The transmitter may also include a node coupled to the first path and the second path and configured such that the low frequency component attenuated signal and the amplified signal combine at the node. A fluid dynamic force is created by the blade assembly to direct the stover with the aid of the housing to an output port.
