  • SYSTEM AND METHOD FOR MINIMIZING FUEL CELL DEGRADATION AFTER SHUTDOWN
    Publication number: 20130323616
    Abstract: A system and method is provided for minimizing the degradation of a fuel cell after shutdown by forcing remaining air out of a fuel cell system. Upon fuel cell shutdown, the flow of air to the cathode of the fuel cell can be kept at a low rate. The flow of cathode exhaust gases along an exhaust conduit is substantially restricted while the pressure of the supply air supplied is increased. As a result, the pressure of the cathode exhaust gases in the exhaust conduit increases. The voltage of the fuel cell can be to deplete the oxygen in the supply air. The pressure of the supply air is decreased to a pressure lower than the pressure of the cathode exhaust gas in the exhaust conduit such that the cathode exhaust gas flows backward through the system to push out any remaining air.

  • Method for calibrating an assembly using at least one omnidirectional camera and an optical display unit
    Patent number: 8599258
    Abstract: A method for calibrating an assembly consisting of an omnidirectional camera (2) located on a vehicle (1) and an optical display unit. An image displayed by the display unit reproduces a perspective of an imaginary virtual camera above the object (1), an image from the virtual camera is projected into an object coordinate system and resulting coordinates (XW, XW.Y) are projected into the omnidirectional camera. During the projection of the image of the virtual camera into the object coordinate system, pixels (xp) of the image of the virtual camera within an imaginary circle or ellipse (1) around the object are projected onto an imaginary plane, while pixels (xp) of the image outside the circle or ellipse are transformed by the virtual camera into the object coordinate system in such a way that they are projected onto an imaginary surface that rises from the edge of the circle or ellipse.

  • Method for unreleasable fastening
    Patent number: 8595914
    Abstract: The invention relates to a method for the unreleasable fastening of at least one component to a basic component with the aid of a bolt projecting through a bore in the component or components, first the bolt being welded electrically with one end face on the surface of the basic component and subsequently being deformed plastically. So that components consisting of any desired materials can be used, it is proposed, according to the invention, that the shank of the bolt, which has a head, be upset, until the underside of the head lies in regions on the surface of the component. Furthermore, an unreleasable connection of one or more components to a basic component is proposed.

  • Safety belt for a vehicle
    Patent number: 8596677
    Abstract: A seat belt for a vehicle includes a belt webbing with several belt webbing layers and, in a shoulder belt region and a lap belt region, a belt interior located between at least two belt webbing layers to which a gas can be applied. The belt webbing is routed through an opening of a latch plate which is insertable into a buckle, by means of which latch plate the belt webbing is, if the seat belt is fastened, deflected at a lower deflection point in a transitional region from the lap belt region to the shoulder belt region. A gas passage connecting at least two sections of the belt interior is provided at the lower deflection point between the at least two belt webbing layers. The gas passage is a tube that is flexible at least in the radial direction. The flexible tube is plastically or elastically deformable.

  • Motor vehicle having a system for feeding fluid into another medium, particularly for feeding a reducing agent into the exhaust gas of an internal combustion engine
    Patent number: 8590292
    Abstract: In a system for feeding fluid into an exhaust gas after-treatment system, during operation fluid is fed via a feed line of the dispensing unit from a main container and is partially returned via a return line to the main container. A diaphragm pressure container is provided on the feed line downstream of a pump and a non-return valve toward the dispensing unit. During operation of the pump, the diaphragm pressure container is filled with fluid. The diaphragm pressure container is emptied as soon as the pump stops operating. In this way, the dispensing unit is cooled even after the operation of the system has ended, thereby protecting electronic components of the same from overheating.
