Patent number: 7478486Abstract: System and method for controlling an appliance for drying clothing articles is provided. The appliance has a container for receiving the clothing articles. A motor is provided for rotating the container about an axis. A heater is provided for supplying heated air to the container during a dry cycle. A sensor is provided for providing a signal indicative of moisture content of the articles. Memory is provided memory for storing historical stop time data of respective dry cycles. A noise-reduction filter is coupled to receive the signal from the moisture sensor to provide selectable filtering to that signal. A timer provides a signal indicative of elapsed time upon start of the dry cycle. A module is responsive to the historical data in the memory for determining an initial estimate of the stop time of the dry cycle to be executed. A processor allows for estimating the stop time of the dry cycle as the cycle is being executed.Type: GrantFiled: January 20, 2006Date of Patent: January 20, 2009Assignee: General Electric CompanyInventors: William Joseph Wunderlin, Michel Dion, Alexander Carswell Cambon, Mahmoud Fariz Ismail, Zubair Hameed, Cathy Diane Emery
