  • Patent number: 6128193
    Abstract: The present invention relates to two modules containing electronic equipment, one relatively small, and one relatively large, that will be physically connected and used for extended operation in an environment where the ambient atmosphere contains moisture filled air or some other specified environmental contaminant. An absorber such as desiccant of a prescribed amount is contained within at least the relatively large module to control the absolute humidity and/or environmental contaminants within each module during extended operation in the ambient environment. Permeable wall portions are placed in the region between the relatively small module and the relative large module to allow for moisture and/or other specified environmental contaminants to pass from the relatively small module to the relatively large module. As such, the lifespan of the small module can be extended.

  • Patent number: 5884486
    Abstract: The invention relates to apparatus and method for efficiently removing humidity from a chamber. A thermoelectric cooler with a maintained temperature differential between the cool and warm sides of the cooler is used to condense the humidity from within the chamber upon the cool side of the cooler. The condensate is transferred to the warm side of the cooler and then removed through the capillary penetration into a porous structure of an evaporator at the warm side of the cooler and further evaporation. During evaporation, the condensate extracts heat from the warm side of the cooler, the temperature of the cool side of the cooler being also decreased, which results in an increase of the overall efficiency of the apparatus.
