Abstract
An electrically conductive heated glass panel assembly, control system, and method for producing panels are provided to warm objects and to insure unobstructed viewing through glass by removing moisture. An integrated connection circuit interconnects glass sheets, which have a low emissivity conductive coating deposited thereon. The circuit includes copper bus bars that are disposed onto the conductive coating through the use of a circularly rotating or an inline heating head and mask apparatus. A metallic tab, which extends from the glass sheet'"'"'s peripheral edge, is disposed onto each conductive metal bus bar for external electrical connectivity. Two types of glazing channels are offered to interconnect multiple panels to external circuits and controls. A solid-state controller may be provided to obtain sensor control signals so as to drive a triac circuit that provides current flow through the panel for the desired heating.
