    摘要： The invention in one embodiment is an improved variable speed engine/generator set with an integrated power conditioning system and control method including load shedding to generate high quality AC power with improved fuel efficiency and reduced emissions. The variable speed generator control scheme allows for load adaptive speed control of engine and generator field. The transformerless power inverter topology and control method provides the necessary output frequency, voltage and/or current waveform regulation, harmonic distortion rejection, and provides for single phase, or unbalanced loading.

    摘要： An overmolded pressure sensor package is provided. The pressure sensor die (Pcell) is capped so that the Pcell has enhanced rigidity to withstand stress effects produced by the molding encapsulant. The Pcell cap includes a hole located away from the Pcell diaphragm, so that external gas pressure can be experienced by the Pcell, while at the same time directing moisture away from the diaphragm. Gel does not need to be used, and instead a soft film can be deposited on the Pcell to protect the Pcell diaphragm from excess moisture, if needed. The Pcell cap can take the form of, for example, a dummy silicon wafer or a functional ASIC.

    摘要： The present application is directed to methods of operating a multi-color image forming device in a mono-color mode. The methods may include performing three basic loops during the printing in the mono-color mode. A first loop may include printing mono-color pages up to an initial preset maximum. The preset maximum may prevent a wear mark from forming on the non-operational PC members due to rubbing against the moving ITM. A second loop may occur when the mono-color pages exceeds the initial preset maximum. The second loop may include rotating the non-operational imaging stations to prevent wear. A third loop may occur when the number of mono-color images exceeds an overall maximum number. The third loop may include resetting the non-operational image forming stations to allow for continuing printing in the mono-color mode.

    摘要翻译： 本申请涉及以单色模式操作多色图像形成装置的方法。 所述方法可以包括在单色模式下在打印期间执行三个基本循环。 第一循环可以包括打印单色页面，直到初始预设最大值。 预设的最大值可以防止由于摩擦移动的ITM而在非操作的PC构件上形成磨损痕迹。 当单色页面超过初始预设最大值时，可能会发生第二个循环。 第二回路可以包括旋转非操作成像站以防磨损。 当单色图像的数量超过总体最大数量时，可能会发生第三个循环。 第三循环可以包括复位非操作图像形成站以允许以单色模式继续打印。

    摘要： An imaging system including a plurality of developing stations for developing an image on a sheet, a releasably removable image receiving module having at least one exposing unit and an image receiving substrate and a support structure for receiving the releasably removable image receiving module. The releasably removable image receiving module is configured to engage the support structure of the system such that the image receiving substrate of the module can be disposed in an operative relationship with the developing stations when the removable module is engaged with the support structure. This imaging system provides a method for upgrading, downgrading or modifying the imaging system that could be substantially performed by an end user. This imaging system may be embodied in a monocolor or multicolor printer, copier, facsimile machine or other electrophotographic based apparatus.
