    • In a method and system for matching learning objects with a user profile, a top-level concept structure, including a keyword hierarchy for each of one or more top-level concepts, can be used to determine the complexity of a learning object. The learning object can include one or more learning object keywords related to one or more top-level concepts contained in the top-level concept structure. The learning object keywords can be assigned a complexity score based upon their location within the keyword hierarchy, and the complexity scores for all of the learning object keywords relating to a top-level concept can be aggregated to generate a learning object top-level concept complexity score. The learning object top-level concept complexity score can be compared with a user's experience rating for that top-level concept and be used to select an appropriate learning object.
    • 在用于将学习对象与用户简档相匹配的方法和系统中,可以使用包括用于一个或多个顶级概念中的每一个的关键字层次结构的顶级概念结构来确定学习对象的复杂性。 学习对象可以包括与包含在顶级概念结构中的一个或多个顶级概念相关的一个或多个学习对象关键字。 学习对象关键字可以根据其在关键词层次结构中的位置被分配复杂度分数,并且可以聚合与顶级概念相关的所有学习对象关键词的复杂度得分,以生成学习对象顶级概念复杂度 得分了。 学习对象顶级概念复杂性得分可以与用户对顶级概念的体验评级进行比较,并用于选择适当的学习对象。

    • Heat and pressure fusing apparatus for fixing toner images. The fusing apparatus is characterized by the separation of the heat and pressure functions such that the heat and pressure are effected at different locations on a thin flexible belt forming the toner contacting surface. A pressure roll cooperates with a non-rotating mandrel to form a nip through which the belt and copy substrate pass simultaneously. The belt is heated such that by the time it passes through the nip its temperature together with the applied pressure is sufficient for fusing the toner images passing therethrough. The non-rotating mandrel is adapted to having its axis skewed relative to the axis of the pressure roll. A pair of edge sensors are provided for activating as mandrel skewing mechanism. Skewing of the mandrel by such mechanism effects proper belt tracking.
    • 用于定影调色剂图像的热压定影装置。 定影装置的特征在于分离热和压力功能,使得热和压力在形成调色剂接触表面的薄柔性带上的不同位置处实现。 压力辊与非旋转心轴协作以形成辊隙,带和复制衬底通过辊隙同时通过。 带被加热,使得当其通过压区时,其温度与所施加的压力一起足以使通过其的调色剂图像定影。 非旋转心轴适于使其轴相对于压力辊的轴线倾斜。 提供一对边缘传感器用于作为心轴倾斜机构启动。 通过这种机制使心轴的扭曲影响适当的皮带跟踪。

    • Heat and pressure fusing apparatus for fixing toner images. The fusing apparatus is characterized by the separation of the heat and pressure functions such that the heat and pressure are effected at different locations on a thin flexible belt forming the toner contacting surface. A pressure roll cooperates with a stationary mandrel to form a nip through which the belt and copy substrate pass simultaneously. The belt is heated such that by the time it passes through the nip its temperature together with the applied pressure is sufficient for fusing the toner images passing therethrough. A release agent management (RAM) system comprising low mass donor and metering rolls, one of which is in contact with the belt, applies silicon oil to the belt without unacceptably reducing the fusing capability of the belt.
    • 用于定影调色剂图像的热压定影装置。 定影装置的特征在于分离热和压力功能,使得热和压力在形成调色剂接触表面的薄柔性带上的不同位置处实现。 压力辊与固定心轴协作以形成辊隙,带和复制衬底通过辊隙同时通过。 带被加热,使得当其通过压区时,其温度与所施加的压力一起足以使通过其的调色剂图像定影。 包括低质量供体和计量辊的脱模剂管理(RAM)系统,其中一个与带接触,将硅油施加到带上,而不会不可接受地降低带的熔合能力。
