The invention reduces test development time for a circuit by determining the longest delay through each circuit element input and output pin. The moving device is movable between a first position and a second position, to move a detector including a detection surface relative to an opposing member disposed opposite the detector. When the device is inserted into its completely-in-the-canal position, the core assembly extends from the sealing retainer to the cartilaginous region of the ear canal in a non-occluding fashion, thereby minimizing interference with hair and earwax production present in the cartilaginous region. When the outer electrodes and are soldered onto a circuit board, the Au layers as the second, fourth, and sixth layers are dissolved into solder, whereas the Cr layers as the third and fifth layers, which hardly form an intermetallic compound with solder, are separated to remain in solder. Moreover, the anchors of the present invention are secured to the substrate in such a manner that removal of the insulation layer has little to no affect on the anchoring of the mechanical structures to the substrate. Application controls self-adaptive analysis computing, exception event warning and alarming privilege graded setting, event data package combination, network digital communication, data storage circuit area management, safety information data storage management and remote emergent calling of the remote mobile monitoring devices.
