A fatigue testing system provides simultaneous cycle testing for a plurality of prosthetic devices under simulated physiological loading conditions. The membrane comprises crosslinked polymer formed by an acid catalyzed crosslinking reaction from a cellulosic polymer and a crosslinking agent. Meltdown of the energy directors during a pressure and ultrasonic welding cycle enable self-leveling of the carbon fiber portions whereby uniform distribution of carbon fiber over the entire cross section of each of the carbon fiber portions of the assembly may be attained. A plurality of primary units are each operatively connected to a utility meter to sense operational data of the utility meter and transmit the data through the network. Cylindrical pins are each engaged by a corresponding one of a plurality of coil compression springs for biasing the pin outward from the recess against said fixed surface for holding the ratchet wheel against rotation in a direction opposite the driven direction of rotation. A further purpose of this invention is to provide a targeted treatment system which allows planning of tissue to be treated, targeting of specific areas of tissue in reference to the plan, and delivering the treatment to the targeted tissue.
