Abstract: A method and apparatus for recovering the resolution lost when the FPA FLIR receiver scans the image at a first predetermined frequency to avoid flicker on moving objects. The input image contains 960 lines of coarse resolution data and the output field requires 480 lines of fine resolution data. The processor delays the sampling of the even numbered channels so that these samples occur between the samples taken by the odd numbered channels. The output circuit combines the signals from the odd numbered and even numbered channels which appear on two separate input lines thereto into one interleaved output on an output line. Since the detector elements overlap by 50 percent, the resulting data has increased horizontal resolution at the expense of a slight vertical distortion. More specifically, the processor combines an even numbered line with the odd numbered line thereabove in the first field and with the odd numbered line therebelow in the second field to increase vertical resolution.

Abstract: An electronic monitoring system for a refrigerated unit has sensing means responsive to temperature within the unit, conditions of the engine driving a compressor, security controls of the unit, all interconnected with solid state programming means in order to provide visual, audio, and transponding alarms in the event of a malfunction within the unit.
