The present invention is directed to a protective apparatus for housing and protecting sensitive components disposed therein, such as a central processing unit or a hard drive. A second circuit is coupled to at least one user-accessible button and is configured to conduct a second signal in response to a user actuation of the at least one user-accessible button if the plurality of line terminals are coupled to a source of AC power, the second signal not simulating the fault condition. Each connection terminal is connected to a corresponding connection pad of the substrate by means of a spot of solder paste. Since the phase control unit provides the effect of controlling the fan motor’s output power and rotational speed, it enables the fan to have increased rotational speed and provide improved heat dissipation and ventilation effects. These predictive conditions can include information about the upcoming terrain of the route along which the vehicle will travel. One sentence including at least the designated character data is cut out and subjected to sentence analysis to extract a keyword.
