A quick release illumination flare mounting arrangement particularly adapted for use in an aircraft. Control circuitry of an imaging system can restore an image by removing image blurring introduced by the lens, sensor noise introduced by the sensor, and a signal offset between multiple channels of the image. The display interface is received in a guide structure that has a bearing portion engaging the outer surface of the frusto-spherical shell, and a second bearing portion engaging the inner surface of the frusto-spherical shell. Then, the subconstellation that requires the least amount of power to generate is selected as the pruned constellation for use by the transmitter. Thus, upon rupture of the first membrane the layer of fire retardant material immediately above it is released and the further membrane comes to rest upon the lower surface of the container, the layer of fire retardant material immediately above the further membrane being released only upon subsequent rupture of the further membrane. The guide mounted to the frame includes a plurality of guide portions having supporting surfaces arranged at predetermined different heights and on which the plurality of process cartridges are detachably placed, and is configured to guide the plurality of process cartridges placed on the supporting surfaces along a path between respective first positions and respective second positions.
