A card-edge connector for fixing and electrically connecting at least a first electrical card and a second electrical card to a circuit board includes a first insulating housing having a first card receiving slot and a second insulating housing having a second card receiving slot. The routine then applies a rule to determine a preferred position value from among the reports and issues a second set of position-specific actuation commands to all of the actuators. The system also resolves the cause of the failure. In addition, the interference stress is especially tailored to assure physical integrity of the glass-alloy composite wire product. A lower rotatable inner drill string is coupled to the upper rotatable tubular inner drill string and is disposed within the interior passageway of the drill bit. Moreover, the wall of the micro-scale channel and the constituent particles are configured such that collisions between the constituent particles and the wall are substantially specular.
