A glass heating system includes a low emissivity sheet of coated glass and an optical sensor mounted on the surface of the glass for optically detecting condensation on the glass. The low emissivity glass is economical to produce and provides superior thermal properties. The low emissivity glass has improved thermal characteristics for use in insulating glass doors for freezers and refrigerators. The optical sensor is positioned between the sheets of glass in the insulating glass unit for detection of moisture on the outer surface. When condensation is d...
[ What is claimed is:] [1.] A refrigerated cabinet door adapted to be mounted on a refrigerated cabinet, said door comprising:a first sheet of glass adapted to be positioned adjacent the ambient environment of the refrigerated cabinet and a second sheet of glass adapted to be positioned adjacent the interior of the refrigerated cabinet, each sheet of glass having an unexposed surface and an outer surface;a conductive coating applied to the unexposed surface of said first sheet of glass, said conductive coating having a hemispheric emissivity of less than...
