A vapor exchange medium comprises a multiplicity of porous desiccant particles and a binder holding the particles together to form a solid shape. The binder includes a multiplicity of substantially spherical, covalently-bonded silica particles derived from a silica sol which are small enough to ensure sufficient covalent bonding of the silica particles to maintain the structural integrity of the vapor exchange medium, yet large enough relative to the pore size of the desiccant particles such that the silica particles do not materially adversely affect the adsorption properties of the desiccant particles. The vapor exchange medium may be impregnated into a fibrous carrier to form a heat exchange element or device. A method and apparatus for making a heat exchange device or element for air conditioning are also disclosed.

Method of making a vapor and heat exchange element for air conditioning

The present invention is an apparatus for producing and delivering high-intensity light to the eyes of a subject to modify the subject's circadian phase. The apparatus includes a support for positioning the apparatus above the eyes of the subject, a light generator for producing a cool, high-intensity light which is radiated to the eyes of the subject, and a power source coupled to the apparatus for supplying power to the light generator. The support of the invention is preferably a visor which does not obstruct the subject's vision when positioned on the head.
