A method for compensating a digital image for the effects of flare light in order to generate an enhanced digital image operates upon a source digital image derived from an original scene affected by imaged flare light, wherein the source digital image includes a plurality of pixels with a known relationship to the intensity of light corresponding to the original scene. An apparatus may comprise a server having an event notification component. The ring is rotated by the motor assembly and the pulley assembly is configured to provide a second reduction of rotation to the ring relative to motor rotation, whereby the ring is driven via at least a double reduction of rotation relative to rotation of the motor, and the cable, the plurality of pulleys, and the ring provide a one-way mechanism. 025 to 30 wt % of a polycyclic aromatic hydrocarbon derivative, and 55 to 99. Environmental conditions that may be modified include air humidity, air temperature, air purity, and air stratification. The liquid exists in the first flow path and the second flow path and the gas mixture circulates in the heat exchange circuit.
