  • Publication number: 20120239283
    Abstract: A system and method for determining fuel consumption and travel range of an electric hybrid vehicle, such as an electric hybrid fuel cell vehicle. The method includes converting the output current of a battery to a virtual consumed fuel consumption flow value and then adding the virtual consumed fuel consumption flow value to an actual consumed fuel value to get a total consumed fuel value that is then divided by the travelled distance of the vehicle to get the fuel consumption of the vehicle. The method also includes converting the SOC of the battery to a virtual available fuel value and then adding the virtual available fuel value to an actual available fuel value to get a total available fuel value that is then divided by the fuel consumption to get the travel range of the vehicle.

  • Publication number: 20120001068
    Abstract: The invention relates to a method for electron diffraction tomography in a Transmission Electron Microscope. Known methods involve using Scanning Transmission Electron Microscope, and use the scanned beam for STEM diffraction. The invention proposes to form the diffraction patterns with a stationary beam with a diameter slightly larger than the crystal, as a result of which a TEM without STEM unit can be used. Finding the crystal is done in TEM mode. Advantages of the method according to the invention are: a TEM without scanning unit can be used, and the diffraction volume is not depending on the orientation of the crystal, as the whole crystal is illuminated while obtaining the diffraction pattern.

  • Patent number: 7811687
    Abstract: A fuel cell system includes a fuel cell stack, an anode reactant source and a shut-off valve that selectively prohibits anode reactant flow from the anode reactant source to the fuel cell stack through a conduit. A control module initiates closure of the shut-off valve to prohibit anode reactant flow through the conduit and determines a shutdown schedule based on a residual mass of the anode reactant within the conduit. The control module operates the fuel cell system using the residual mass and based on the shutdown schedule.

  • Patent number: 7562627
    Abstract: The present invention relates to a pyrotechnic system, system-compatible pyrotechnic objects, and a firing method tailored to the system. The system comprises a starting device having multiple receptacles, having a connection channel between each of the receptacles. The receptacles are filled with the pyrotechnic objects, the first receptacle is provided with an additional ignition device, and the pyrotechnic object located therein is ignited. An igniter externally positioned on the pyrotechnic object conducts the ignition energy into the interior and simultaneously via the connection channel into the neighboring receptacle. A pyrotechnic object located therein is ignited. The igniter externally positioned on the pyrotechnic object partially causes a time delay. The delay time may be set by twisting the pyrotechnic object in relation to the connection channel.

  • Publication number: 20090117170
    Abstract: The present invention of a segmented release device (sandwich construction with reservoir) for molecules (active compounds, medicaments, diagnostic, therapeutic and chemical reagents) is based on a construction which makes possible a constant release rate through diffusion-permeable intersegment films partially or completely filled with liquid of the neighboring media. The molecules pass here from the reservoir of the device into the outer medium by diffusion exclusively through the intersegment films. These intersegment films are adjustable in their thickness and composition in the manner specified in each case. The release rate can be determined in advance and thus also calculated within wide limits by the structure and geometry of the segmented device and by the number, composition and dimensions of the thin intersegment films. The device according to the present invention allows the adjustment of an extremely precise release rate of the molecules.

  • Publication number: 20080176111
    Abstract: A power request controller that prevents a power request signal to a fuel cell stack controller from providing more compressor air and hydrogen gas than is necessary to meet the current power demands of the vehicle. The stack controller generates a signal of the available current from the fuel cell stack. This signal and the measured current actually being drawn from the stack are received by a proportional-integral (P-I) controller in the power request controller. If the available stack current is significantly greater than the stack current being used, the P-I controller will provide an output signal that reduces the power request signal to the stack controller so that the current produced by the stack and the current being drawn from the stack are substantially the same. A transient detector turns off the P-I controller so that it does not reduce the power request signal during an up-power transient.
