The present invention is directed to a geosynthetic wicking fabric for transporting water from beneath pavement structures to reduce or prevent damaged caused by frost heave and thaw. The test fixture is made up of a probing platform to accept and heatsink an IC. A second flow valve is in fluid communication with the first valve and the inlet. The physiological monitor has a polarized light source for illuminating tissue and a magnetic field generator which creates a magnetic field within the tissue during illumination. The estimation part of the received preamble is compensated by this estimate. The guide stylet is capable of moving in a plurality of degrees of freedom in the airway following the guidance from the navigation element.
