A fiber optic assembly comprising an adapter assembly defining an internal cavity, a first end for a receiving a first fiber optic connector, and a second end for receiving a second fiber optic connector, wherein the first and the second fiber optic connectors are dissimilar. In many embodiments, the actual dye specific scale factor automatically selected by the scanner is one that is equal to a preset \u201cmaster\u201d scale factor, so that the scanner reads any supported dye using the same constant scale factor. The apparatus further includes vias formed through the core to electrically couple the first traces to the second traces, and a stiffening structure coupled to the first side of the flex circuit substrate to increase structural rigidity of the flex circuit substrate. In each interval the delay value having the highest signal-to-interference ratio is selected and provided to the RAKE unit with each selected delay being assigned to a RAKE finger. By modifying a therapy delivery parameter, the defibrillator may deliver defibrillation pulses at an energy level that is supportable by the circuit. The drip flange extends outward from the top of the base portion.
