    • The present leverages data hierarchies to provide a systematic means to determine data differences between equivalent data. This allows disparate data storage systems to efficiently determine divergent data locations by utilizing, for example, data signatures representative of varying degrees of data granularity. Comparative analysis can then be performed between the databases by employing an iterative approach until the desired level of data granularity is obtained. This allows, in one instance of the present invention, discrepant data to be determined without the transfer of large amounts of data and without requiring homogeneous data storage systems. Another instance of the present invention utilizes equivalent logical data views from non-identical data sets to determine data discrepancies. Yet another instance of the present invention determines discrepancies of a federated and/or integrated data system by employing reversible data statistical signatures, providing a simplistic transfer protocol and sheltering each data system from the other's complexities.
    • 本发明利用数据层次来提供确定等效数据之间的数据差异的系统手段。 这允许不同的数据存储系统通过利用例如代表不同程度的数据粒度的数据签名来有效地确定发散数据位置。 然后可以通过采用迭代方法在数据库之间进行比较分析,直到获得期望的数据粒度水平。 这在本发明的一个实例中允许在不传输大量数据而不需要均匀数据存储系统的情况下确定差异数据。 本发明的另一个实例使用来自不相同数据集的等效逻辑数据视图来确定数据差异。 本发明的另一个实例通过采用可逆数据统计签名来确定联合和/或集成的数据系统的差异,提供简单的传输协议并且避免每个数据系统与其他复杂性。

    • A communication system includes a master device which communicates with a chain of serially-connected slave devices. The master originates messages, each of which is intended for a particular ‘target’ slave device. Each message contains a ‘distance to target device’ value equal to the number of devices between the master and target, and a data packet containing data to be conveyed between the master and target. Each slave device determines if the ‘distance to target device’ value indicates that it is the target. If not, the slave device increments or decrements the value in real time, with no latency, and transmits the modified message to the next slave device until received by the target device. In one embodiment, the target device may place data in the data packet, and the slave devices are arranged to buffer the data back to the master device.
    • 通信系统包括与串行连接的从设备链通信的主设备。 主机产生消息,每个消息都用于特定的“目标”从设备。 每个消息包含一个“到目标设备的距离”值​​等于主设备和目标设备之间的数量,以及包含要在主设备和目标设备之间传送的数据的数据包。 每个从设备确定“到目标设备的距离”值​​是否表示它是目标。 如果没有,则从设备实时地增加或减少该值,没有延迟,并且将修改的消息发送到下一个从设备,直到目标设备接收。 在一个实施例中,目标设备可以将数据放置在数据分组中,并且从设备被布置为将数据缓冲回主设备。

    • A voltage source includes first and second pn junctions which conduct the outputs of respective current sources to establish respective base-emitter voltages Vbe1 and Vbe2 at respective nodes; Vbe1 and Vbe2 can each be generated with a current I or a current N*I. An amplifier A1 has its non-inverting input connected to the second node and its inverting input connected to the first node through an input capacitor; a feedback capacitor is connected between the inverting input and a third node. Switches are connected between A1's inverting input and A1's output, between the third node and A1's output, and between the third node and a circuit common point. A control circuit operates the switches and current sources during first and second operating phases to selectively produce a temperature independent output voltage or a temperature dependent output voltage.
