摘要： The invention relates to a methanol-to-hydrogen cracking reactor for use with a fuel cell vehicular power plant. The system is particularly designed for rapid start-up of the catalytic methanol cracking reactor after an extended shut-down period, i.e., after the vehicular fuel cell power plant has been inoperative overnight. Rapid system start-up is accomplished by a combination of direct and indirect heating of the cracking catalyst. Initially, liquid methanol is burned with a stoichiometric or slightly lean air mixture in the combustion chamber of the reactor assembly. The hot combustion gas travels down a flue gas chamber in heat exchange relationship with the catalytic cracking chamber transferring heat across the catalyst chamber wall to heat the catalyst indirectly. The combustion gas is then diverted back through the catalyst bed to heat the catalyst pellets directly. When the cracking reactor temperature reaches operating temperature, methanol combustion is stopped and a hot gas valve is switched to route the flue gas overboard, with methanol being fed directly to the catalytic cracking reactor. Thereafter, the burner operates on excess hydrogen from the fuel cells.

摘要： The power conversion module includes a power converter coupled to provide a DC output voltage from an input voltage source. The power converter may have primary and secondary stages, and the power converter may also provide a DC output voltage that is electrically isolated from the input voltage source. Additionally, the power conversion module also includes a voltage controller configured to measure a pre-bias value of the output voltage prior to start-up of the power converter and provide a start-up control signal, wherein the start-up control signal corresponds to an initial output voltage that is greater than the pre-bias value of the output voltage. The initial output voltage includes a start-up voltage margin above the pre-bias value and is maintained for a margin hold time. A method of operating a power conversion module is also provided.

摘要： A method for performing motion correction in an autocalibrated, multi-shot diffusion-weighting MR imaging data acquisition includes performing motion correction on k-space data in an autocalibration region for each shot individually and then combining the motion-corrected k-space data from each shot to form a motion-corrected reference autocalibration region. Uncorrected source k-space data points are “trained to” the motion-corrected k-space data from the motion-corrected reference autocalibration region to determine coefficients that are used to synthesize motion-corrected k-space data in the outer, undersampled regions of k-space. Similarly, acquired k-space lines in the outer, undersampled regions of k-space may also be replaced by motion-corrected synthesized k-space data. The motion-corrected k-space data from the motion-corrected reference autocalibration region may be combined with the synthesized motion-corrected k-space data for the outer, undersampled regions of k-space to reconstruct motion-corrected images corresponding to each coil element. The motion corrected images corresponding to each coil element may be combined into a resultant image.

摘要： A computer-aided detection system for evaluating tissue based on a series of timed images acquired both before and after a contrast agent is administered performs a temporal analysis of the tissue and then a spatial analysis in which the tissue is categorized. After the temporal and spatial analysis is performed, the results can be displayed. The displayed results can include both tissue characterization results, underlying curves used to determine the characterization, and confidence data regarding how good the characterization is expected to be. The confidence data can be provided, for example, by using variations in color schemes, displaying numerical confidence levels, or providing graphical features such as piecewise linear models.
