A hanger, for suspending at least one object from a support, includes a base having a top surface, a bottom surface and a cap extending from the top surface of the base. The state machine circuit may, for example, be configured so that the synthesized clock signal is a spread-spectrum clock signal andor a clock signal having a nominal frequency that is greater than a nominal frequency of each of the input clock signals. The reaction products can be used to produce moldings. When the distal reamer is in contact with the positionable element, the distal reamer and proximal reamer are longitudinally offset by a one of a plurality of specified offsets. The air cushioning device further has a magnetic vibratory member for generating vibrations to and through a transmitting member which in turn creates resonance vibrations to the cushioning device and the body part positioned on the cushioning device.
