Abstract: The present invention relates to a cooling system, the cooling system having a nozzle which receives coolant from a reservoir and which faces a substrate. The nozzle may be opened and closed by a thermally responsive valve allowing the coolant to be automatically metered to the substrate, thus controlling the spatial distribution of the coolant that is applied to the substrate. This approach allows hotter areas of the substrate to receive more coolant, thus eliminating nonuniformities in the thermal profile of the substrate.

Abstract: An airship deployment system comprises an airship of unique shape having laminar flow over this shape to enable low power propulsion, capable remote control, comprising an inflatable body; a propeller assembly for station keeping and repositioning said airship and capable of being folded into a compacted position and unfolded into an operational position; and a payload, comprising gas for inflating said inflatable body; and means for transferring data between said airship and a remote location; and a missile for carrying said airship in a compacted state to a predetermined location and altitude, and releasing said airship at said predetermined location and altitude. When said airship is released from said missile said inflatable body is inflated and said propeller assembly is unfolded into said operational position.
