Abstract: A cooking appliance includes a cooktop having a first burner and a second burner, a control knob assembly having a first control knob to control the first burner and a second control knob to control the second burner, a display assembly provided within the cooktop proximate the first burner, an air handler attached to the cooktop proximate the second burner, the air handler being in fluid communication with the display assembly, and a controller operably connected with the cooktop, the control knob assembly, the display assembly, and the air handler, the controller being configured to selectively operate the air handler based on an operational state of the first control knob.

Abstract: A cooktop appliance includes a gas burner. A primary control valve is coupled to the gas burner. The primary control valve is manually adjustable to regulate a flow of gaseous fuel to the gas burner. A secondary control valve is connected in series between the primary control valve and the gas burner. A controller is in communication with the secondary control valve. The controller is configured to receive a temperature measurement from a temperature sensor and to adjust the secondary control valve in response to the temperature measurement from the temperature sensor.

Abstract: A system for characterizing manual welding exercises and providing valuable training to welders that includes components for generating, capturing, and processing data. The data generating component further includes a fixture, workpiece, at least one calibration device having at least two point markers integral therewith, and a welding tool. The data capturing component further includes an imaging system for capturing images of the point markers and the data processing component is operative to receive information from the data capturing component and perform various position and orientation calculations.

Abstract: A method of controlling the operation of a dryer including both a variable heat source and a variable speed blower includes varying only one of the variable heat source and the variable speed blower, while maintaining the other one in a fixed state.

Abstract: An electric clothes dryer heater system including a heater element and a controller operationally coupled to the heater is provided. The controller is configured to provide an AC sine wave to a heater element of an electric clothes dryer, stop providing at a zero crossing of the AC sine wave, monitor the AC sine wave for a subsequent zero crossing and reprovide the AC sine wave to the heater element at the subsequent zero crossing.
