In an exemplary system, a first sampling circuit is coupled to a clock module to receive values therefrom. The first and second cleaning tools are pivotally mounted in the case so as to be movable between a first position within the case to a second position extending outwardly of the case. The one or more unreliable data sources comprise one or more of a sender of the file and one or more peers. The speeds of the first and second fans may be adjusted based on the temperature measurements of the cooling gas pathway groupings. In one exemplary embodiment, the blast panel comprises a first penetration resistant layer on the side facing away from the vehicle, a first core made of a crushable structural material between the first penetration resistant layer and the vehicle, and a shock dissipation layer disposed between the first penetration resistant layer and the first core.
