Abstract: Techniques are provided for an image processing device to receive image information comprising image data for a plurality of mid-wave infrared region (MWIR) channels, where the image data is obtained during a first imaging period and during a second imaging period temporally different from the first imaging period. A plurality of sets of atmospheric wind vectors are calculated using differences between image data obtained during the first imaging period and the image data obtained during the second imaging period for corresponding sets of MWIR channels. An altitude is assigned to the plurality of atmospheric wind vectors in each set based on a brightness temperature of each wind vector and a pre-computed atmospheric temperature profile to generate a set of two-dimensional wind fields comprising one two-dimensional wind field for each set of MWIR channels.

Abstract: A compressor/motor has fluid processing stages, each having ports through which a fluid is accepted in one volume and expelled in another volume. A system of valves selectively couples the ports to define, for a first process of a cycle, a unidirectional fluid path through the fluid processing stages that expels the fluid from path-adjacent fluid processing stages in incrementally smaller volumes. In a second process of the cycle, a reverse unidirectional fluid path is defined by the valves where the fluid expelled from path-adjacent fluid processing stages is in incrementally larger volumes. A mechanical interface coupled to the fluid processing stages conveys a force to the fluid processing stages to compel the fluid through the fluid path in the first process or conveys the force from the fluid processing stages that is compelled by the fluid traversing the reverse fluid path.
