摘要： Methods and apparatus for converting power from a power source are described. In one example embodiment, the method includes controlling multiple transformer and switchgear units coupled to a power source, and controlling multiple converter units connected in parallel. Each converter unit is coupled to a respective one of the transformer and switchgear units to form an individual thread. The transformer and switchgear unit and power converters are controlled so that the carrier waveforms for each individual thread are interleaved between each other over a carrier cycle.

摘要： A gradient amplifier arrangement is described that comprises a gradient amplifier power stage. The device may be employed to provide a current to a gradient coil, as in a MRI system. The circuitry disclosed includes a series coupling of a first bridge amplifier operating at a first voltage, a second bridge amplifier operating at a second voltage, a third bridge amplifier operating at a third voltage, and a gradient amplifier control stage. The amplifiers may provide output voltages at different levels, and may be switched at different times and frequencies to provide a range of output voltage and current levels.

摘要： Methods and systems for application framework development for wireless devices are provided herein. Aspects of the method may include acquiring an MMI event from an MMI event queue within the MMI wireless framework. An identity of the acquired MMI event may be determined and the acquired MMI event may be dispatched to an event handler based on the determined identity of the acquired event. If the acquired MMI event comprises a timing event, the acquired MMI event may be dispatched to an MMI event owner within the MMI wireless framework. If the acquired MMI event comprises a keypad event, the acquired MMI event may be dispatched to a currently active MMI view within the MMI wireless framework. If the acquired MMI event comprises an addressed event, the acquired MMI event may be dispatched to a destination handler within the MMI wireless framework.
