An optical inspection module is provided for detecting defects on a substrate having first and second opposite planar surfaces. Means for Resolution A resin molding body has two faces perpendicular to each other, and also has a total reflecting face 23 approximately having an angle of 45\xb0 with respect to these two faces. The receiving member has an element engaging surface facing away from the base member to receive the load element. Yet another embodiment of the present invention is directed to a method and an apparatus for performing a low voltage pulse test of the electrical integrity of a pipe-in-pipe pipeline, which may be performed during the operation phase of an electrically heated pipe-in-pipe pipeline. IMD-acquired data, drug dispensation data, and patient symptom data are retrieved by a programmermonitor.
