Patent number: 6538238Abstract: A sensor assembly for glass-ceramic cooktop appliances includes an optical detector having an reference component and an active component. The active component is arranged to receive radiation from the glass-ceramic plate, and the reference component is insulated from radiation from the glass-ceramic plate. The sensor assembly further includes a temperature sensor and a heater located adjacent to the reference component and a controller having a first input connected to the optical detector and a second input connected to the temperature sensor. The controller is responsive to the optical detector and the temperature sensor to calibrate the sensor assembly. Calibration is accomplished by noting the temperature reading of the temperature sensor after the burner assembly has not been used for a predetermined period of time to obtain a first calibration point. Then, the burner assembly is activated so that the temperature of the glass-ceramic plate is raised, and the output of the optical detector is noted.Type: GrantFiled: February 12, 2002Date of Patent: March 25, 2003Assignee: General Electric CompanyInventors: Ertugrul Berkcan, Emilie Thorbjorg Saulnier

Patent number: 6462316Abstract: A system for automatically controlling the temperature of the cooking surface of a cooking surface of a solid-surface cooktop and, consequently, the temperature of the cooking utensil on the cooking surface, by detecting cooking utensil-related properties through the solid-surface cooktop. The cooking utensil-related properties include presence/absence, removal/placement, and other physical properties such as utensil type, size, warpage, and temperature and load size. Automatic control is based on monitoring the heat transfer characteristics from the energy source to the cooktop and the utensil to infer the utensil properties. This is achieved by sensing or inferring a parameter indicative of the temperature of a monitored area that includes at least a portion of the cooktop or of the cooking utensil placed on the upper surface of a cooktop, as well as a parameter indicative of power applied to a controllable heat source, and detecting signal properties using an evolutionary algorithm.Type: GrantFiled: October 10, 2000Date of Patent: October 8, 2002Assignee: General Electric CompanyInventors: Ertugrul Berkcan, Vivek Venugopal Badami, Paul Randall Wilson, Emilie Thorbjorg Saulnier

Patent number: 6169486Abstract: A system is disclosed for determining the temperature of a cooktop having an upper surface and a lower surface. At least one controllable energy source is located below the lower surface of the cooktop to heat the area above the energy source on the cooktop, and at least one sensor with at least one detector to detect infrared radiation from the cooktop above the energy source. The level of infrared radiation is representative of the temperature of the cooktop, which may be glass ceramic. The sensor provides a signal indicative of the temperature of the cooktop which is then used to control the energy source in order to protect the cooktop from extreme temperatures. The signal may be alternatively utilized to provide an indication of a hot cooktop surface after the energy sources have been turned off. The signal optionally is also utilized to provide automatic control of the energy source to maintain a predetermined temperature, or to prevent exceeding a maximum temperature.Type: GrantFiled: July 19, 1999Date of Patent: January 2, 2001Assignee: General Electric CompanyInventors: Ertugrul Berkcan, Emilie Thorbjorg Saulnier
