  • Patent number: 7844388
    Abstract: A method of regulating the actual lambda value for an internal-combustion engine of a motor vehicle in a closed control loop is provided. A lambda setpoint is transferred to a controller for influencing an injection calculation for the internal-combustion engine, and an actual lambda value, which occurs at the output of a controlled system as a function of the injection calculation, is returned to the controller. At least one system parameter of the controlled system is determined, and the determined system parameter is transferred to a Smith predictor added to the controller for compensating the influence of the system dead time on the control loop characteristics.
    Type: Grant
    Filed: August 28, 2008
    Date of Patent: November 30, 2010

  • Patent number: 6600139
    Abstract: An appliance control protection apparatus for a glass ceramic cooktop is constructed with a double wall housing and a low voltage cooling fan. The double wall housing is comprised of a first inner wall and a outer wall and prevents the transfer of heat from the heating elements in a glass ceramic cooktop towards the electronic control unit. The first inner wall is adhered to the underside of the ceramic glass panel of the cooktop and the outer wall snaps into position over the first wall, resulting in a space therebetween for insulation. Additionally, the control housing is provided with a low voltage fan that convects heat away from hot spots formed on the electronic control unit toward other components within the control housing. The low voltage fan operates in response to certain operating temperatures within the control housing as detected by a heat sensor.
