  • Zone lumbar massage system
    Patent number: 8162398
    Abstract: A lumbar system for use in a seat includes a frame having a first side and a second side substantially opposite the first side, a pump mounted to the second side of the frame and operable to pressurize air, and a control module mounted to the second side of the frame. The control module is in communication with the pump to receive pressurized air. The lumbar system also includes a plurality of air cells mounted to the first side of the frame. Each of the plurality of air cells individually communicates with the control module to receive variable amounts of pressurized air provided by the pump such that each air cell is independently inflatable. The frame, the pump, the control module, and the plurality of air cells are installable in the seat as a single unit by coupling the frame to the seat.

  • Combustible gas detection systems and method thereof
    Patent number: 7159444
    Abstract: A system and method are provided for monitoring the levels of combustible gas in a gas stream. The system includes means for controlling the relative humidity of the the gas stream to maintain a humidity level in the performance range of combustible gas sensors. A number techniques are illustrated for achieving the humidity control, including, secondary phase separations, mixing the gas with dry air and adjusting of the gas stream temperature.
