Zusammenfassung:	A CONTROL CIRCUIT CAPABLE OF PROPORTIONALLY SUPPLYING ELECTRICAL CURRENT FROM AN ALTERNATE CURRENT POWER SUPPLY TO A GLASS PANE COATED WITH TRANSPARENT CONDUCTIVE OXIDES ON REFRIGERATOR COMPRISES A TRIODE FOR ALTERNATING CURRENT (TRIAC) ELECTRICALLY GATING THE VOLTAGE TO BE SUPPLIED TO THE GLASS PANE; AND A MICRO-CONTROLLER CONFIGURED TO FIRE AN ELECTRICAL PULSE TO THE TRIAC AFTER A PREADETERMINED DELAYED DURATION ONCE DETECTING ZERO CROSSING OF EACH PHASE OF THE ALTERNATE CURRENT; WHEREIN THE TRIAC ALLOWS ELECTRICAL CURRENT CONDUCTION AT EACH PHASE OF THE ALTERNATE CURRENT TO THE GLASS PANE UPON RECEIVING THE ELECTHCAL PULSE AND THE TOTAL ELECTRICAL CURRENT SUPPLIED TO THE GLASS PANE IS INVERSELY RELATED TO THE PRE-DETERMINED DELAYED DURATION.
