  • Multi-valve damper for controlling airflow and method for controlling airflow
    Patent number: 7543759
    Abstract: The present invention relates to a multi-valve damper which divides a section of an airflow duct into at least two airflow sections. The damper has a plug body having a proximal end and a distal end. The plug body is adapted to separate a section of an airflow duct into at least two airflow sections. At least two damper blades may be mounted on the distal end of the plug body, each of the damper blades controlling airflow in a respective airflow section. At least one airflow sensor may be provided in each of the airflow sections for controlling the respective damper blades. An actuator mechanism responsive to the sensors may be provided for opening and closing the damper blades. At least one of the proximal end and the distal end of the plug body may have an aerodynamic shape.

  • Method and apparatus for fluid flow control
    Patent number: 6889700
    Abstract: Methods and apparatus are provided for modulating a flow of fluid in a duct using a rotating member that rotates in the duct. A sensing unit senses the rotation speed of the rotating member and generates a rotation signal as a function of the sensed rotation speed. A control unit receives the rotation signal from the sensing unit and generates a control signal to modify the rotation speed of the rotating member. The apparatus can be self-powering by generating an electric current in response to rotation of the blade.
