    • Drive train motor speed is varied in a manner that compensates for characteristic rotational velocity errors of the associated drive train, such as by modulating a drive train motor speed control signal at a modulation phase and amplitude derived from the characterized rotational velocity error. Characterization can be performed on a test system for each drive train of interest, and the compensation values thus obtained can be saved for later use by systems in which the characterized drive trains are used. Thus, a drive train used in a consumables cartridge for an electrophotographic printing (EP) system can be characterized and the corresponding data saved via a label or memory circuit that is affixed to the cartridge. Such data can be used by the EP system in which the cartridge is installed to more accurately control the velocity of the image forming process members driven by the cartridge's characterized drive train.
    • 传动系电动机速度以补偿相关联的传动系的特征旋转速度误差的方式变化,例如通过调制调制阶段的传动系电机速度控制信号和从特征旋转速度误差导出的振幅。 可以在每个感兴趣的传动系统的测试系统上进行表征,并且可以将由此获得的补偿值保存以供以后使用的特征在于的驱动列车的系统使用。 因此,用于电子照相印刷(EP)系统的消耗品盒中的传动系统可以被表征,并且通过固定到盒的标签或存储器电路保存相应的数据。 这样的数据可以由其中安装盒的EP系统使用,以更精确地控制由盒式传动系驱动的图像形成处理构件的速度。

    • A determination is made as to whether a data type associated with a received logical table definition associated with a database query within a distributed database system differs from a data type associated with a local logical table definition. A data conversion is performed on data retrieved from a locally-stored physical table referenced by the local logical table definition in response to determining that the data types differ. Local data conversion information is created identifying the data conversion performed on the retrieved data in response to performing the data conversion. At least one of the retrieved data and the converted data with the created local data conversion information is forwarded to at least one of a distributed database node and an application-level module. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
    • 确定与分布式数据库系统中与数据库查询相关联的接收到的逻辑表定义相关联的数据类型是否与与本地逻辑表定义相关联的数据类型不同。 响应于确定数据类型不同,对由本地逻辑表定义引用的本地存储的物理表检索的数据进行数据转换。 创建本地数据转换信息,以响应于执行数据转换而识别对所检索数据执行的数据转换。 所检索的数据和具有所创建的本地数据转换信息的转换数据中的至少一个被转发到分布式数据库节点和应用级模块中的至少一个。 该摘要不被认为是限制性的,因为其他实施例可能偏离本摘要中描述的特征。
