  • Electrochemical fuel cell stack
    Patent number: 7485389
    Abstract: An electrochemical fuel cell stack includes a membrane electrode assembly and a distributor plate. The distributor plate includes a channel region having gas channels for distributing reaction gas to the membrane electrode assembly, a first port area for supplying reaction gas to the channel region, and a second port area for removing reaction gas from the channel region. The gas channels are disentangled and each distributed in a respective separate channel area, at least one of the gas channels having at least one deflection point between the first and second port areas.

  • Redundant array of control devices
    Patent number: 7483778
    Abstract: An array of control devices having a plurality of control devices (1-3, 20-23) which are interconnected via a first data bus (4), in a means of transportation, control devices (1-3; 20-23) which are of redundant configuration with respect to a control function being provided, and in each case a data bus isolating switch (5) being assigned to the control devices (1-3; 20-23) which are of redundant configuration, the data bus isolating switch(s) connecting or disconnecting the data bus (4) as a function of an evaluation signal. In order to optimize the redundant array, each of these data bus isolating switches (5) is connected to a signal line of at least one further redundant control device (1-3; 20-23), a further redundant control device (2, 3; 21; 23) transmits an evaluation signal to the data bus isolating switch (5) which is assigned to a first redundant control device (1; 20; 22).

  • Gearshift unit for a transmission of a motor vehicle
    Patent number: 7481128
    Abstract: In a gearshift unit for a transmission of a motor vehicle, wherein a driver of the motor vehicle shift the gears of the transmission by means of a gearshift lever and the gearshift unit has a gearshift power-assist unit to enhance the shift force exerted by the driver of the vehicle, a control device is provided which detects a significant increase in a moment of inertia, in excess of a normal amount, of masses to be accelerated in the event of a gearshift in the transmission and actuates the gearshift power assist unit to assist the shift forces only when no significant increase in the moment of inertia has been detected in order to prevent high shifting forces from being generated when they might lead to damage to the transmission.

  • Reactor for autothermal reforming of hydrocarbons
    Patent number: 7481856
    Abstract: A reactor for autothermal reforming of hydrocarbons that allows a reduction of excess-air factor ? during the reforming without resulting in a reduced conversion of the hydrocarbons in an end region of the reaction zone. The reactor includes at least one reaction zone in which is arranged at least one catalyst structure for the reformation so that the educts involved in the reformation are converted while flowing through the reaction zone. A heating device is included for heating the end region of the reaction zone to accelerate the conversion of the hydrocarbons.

  • Shaft for a motor vehicle steering column and associated assembly process
    Patent number: 7481459
    Abstract: The present invention concerns a steering shaft (4) of a steering column (1) and (4) for a motor vehicle steering assembly (2), wherein the steering shaft (4) includes a cylinder body (11) and a piston rod body (12) inserted telescopically therein, and on one end is connectible with a steering wheel (6) and at the other is connectible via a steering coupling (5) with a steering gear (7). The assembly of the steering shaft (4) can be simplified thereby, that the steering shaft (4) includes at least one (1) pneumatic connection (13), which communicates with a cylinder space (14), which is provided in the cylinder body (11) and which cylinder space is axially bordered from the piston rod body (12), in such a manner, that pressure actuation of the cylinder space (14) drives the piston rod body (12) to extend from the cylinder body (11).

  • Method and Device for Recognizing Tiredness
    Publication number: 20090021356
    Abstract: In a method and in a device for detecting when the driver of a motor vehicle becomes tired, the tiredness is determined as a function of a detected steering inactivity phase and a subsequent steering action. In this context, the steering inactivity phase is logically combined with the steering actions and the logic combination is stored at various times. The logic combination is stored with an assigned weighting factor, and the weighting factor is determined as a function of a classification of a steering situation.

  • Method and device for detecting the initiation of the driving off process by a driver of a vehicle
    Patent number: 7480545
    Abstract: A method and a device are for detecting the initiation of the driving off process by a driver of a vehicle. The time derivatives of the engine torque and of the engine speed are determined, and the initiation of the driving off process is then inferred from an evaluation of these time derivative values. The detection of the driving off process can be used for releasing a brake while avoiding unintentional rolling of the vehicle when making a hill start.
