A solution for packaging an optoelectronic device using an ultraviolet transparent polymer is provided. The subframes represent time periods during which a base station may grant the relay node permission to transmit to the base station on a first frequency. Drive-level bearing friction values are then calculated using the computed torque values and then combined into a composite indicator. The bump is disposed on the metallic pad. In another embodiment, the system is positioned extracorporeally, with the inflow conduit and outflow conduit applied percutaneously to a non-primary vessel for circulating blood to and from the non-primary vessel or between the non-primary vessel and another blood vessel within the patient’s vasculature. The skirt portion is adapted to cover a backside of the chair.
