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: 6474155Abstract: An integrated sensor for automated systems includes a flow sensor, a temperature sensor, and a network interface. In a particular embodiment of the invention, the flow sensor includes a temperature sensor (26) which determines the temperature of the fluid flowing in a flow path (12). A heater (18) is coupled to the flow path, and is energized by a controller (20) with sufficient electrical power to raise the temperature of the heater above the measured fluid temperature by a fixed temperature difference. In order to aid in determining the temperature difference, a sensor (24) may be associated with the heater (18). The amount of power required to maintain the temperature difference is a measure of the flow velocity. The volumetric flow rate is the product of the flow velocity multiplied by the area of the flow sensor. The mass flow rate is the product of the volumetric flow rate multiplied by the mass density of the fluid.Type: GrantFiled: July 8, 1999Date of Patent: November 5, 2002Assignee: Lockheed Martin CorporationInventors: Ertugrul Berkcan, Scott Baxter Hoyle

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: 6417513Abstract: An apparatus detects changes in water vapor above a cooktop surface and includes a radiation source that is positioned below the cooktop surface. The radiation source emits radiation having a predetermined water vapor absorption wavelength. A beam splitter splits the emitted radiation into a first radiation beam and a second radiation beam. The first radiation beam is directed through and above the cooktop surface. A reflective surface positioned above the cooktop surface reflects the first radiation beam. A radiation sensor detects the reflected first radiation beam and generates a sensor output. A reference radiation sensor receives the second radiation beam from the beam splitter and generates a reference output. A processor is connected to the radiation sensor and the reference radiation sensor and receives the sensor output and the reference output. Changes in water vapor above the cooktop surface are determined by analyzing the sensor output and the reference output.Type: GrantFiled: December 28, 2000Date of Patent: July 9, 2002Assignee: General Electric CompanyInventors: John Erik Hershey, Ertugrul Berkcan
