    摘要： Systems and methods for analyzing structural test data are disclosed. In one embodiment, a method includes applying a sequence of loads to a test article, receiving raw test data indicative of the applied loads from at least one sensor operatively associated with the test article, receiving predicted test data indicative of the predicted loads on the test article, filtering out invalid test data, cycle counting to pair loads in the test data, performing a first fatigue damage computation based on the raw test data, performing a second fatigue damage computation based on the predicted test data, and comparing the first and second fatigue damage computations. The filtering, cycle counting, and performing of the first and second fatigue damage computations, and the comparison of the first and second fatigue damage computations, may be performed simultaneously using a spreadsheet program.

    摘要： The present invention relates to a method for preparing a lithium vanadium phosphate material comprising mixing water, lithium dihydrogen phosphate, V2O3 and a source of carbon to produce a first slurry; wet blending the first slurry; spray drying the wet blended slurry to form a precursor composition; milling the precursor composition to obtain a milled precursor composition; compacting the milled precursor to obtain a compacted precursor; pre-baking the compacted precursor composition to obtain a precursor composition with low moisture content; and calcining the precursor composition with low moisture content at a time and temperature sufficient to produce a lithium vanadium phosphate. The lithium vanadium phosphate so produced can optionally be further milled to obtain the desired particle size. The electrochemically active lithium vanadium phosphate so produced is useful in making electrodes and batteries and more specifically is useful in producing cathode materials for electrochemical cells.

    摘要： The invention relates to a control method and a controller for a DC-DC converter, such as a synchronous Buck converter, which exploits the principle of capacitor charge balance to allow the converter to recover from a positive and/or negative load current step in the shortest achievable time, with the lowest possible voltage undershoot/overshoot. The control method may be implemented by either an analog or a digital circuit. The controller may be integrated with existing controller schemes (such as voltage-mode controllers) to provide superior dynamic performance during large-signal transient conditions while providing stable operation during steady state conditions. The invention also relates to a method and a modification of a DC-DC converter topology that comprises connecting a controlled current source between an input terminal and an output terminal of the DC-DC converter; detecting a load current step to a new load current; modifying a duty cycle of the DC-DC converter; and modifying current through a parallel output capacitor of the DC-DC converter by controlling current of the current source. The methods and circuits provided herein are applicable to Buck converters and Buck-derived converters such as forward, push-pull, half-bridge, and full-bridge converters.
