    摘要: A real time data analysis and data filtering system for managing streaming data is presented. The method breaks a stream of data into a set of queues that are themselves streaming data but that are handled separately by unique processing steps. The queues are dynamically created on an as needed basis based on inspection of the data. In this manner the speed and efficiency of parallel processing is applied to serially streaming data. A method of filtering the data to present the new streaming data queues is also described. The method makes use of keys that are used to filter the data stream into individual queues. In another embodiment a pre-processing step includes creation of keys and insertion of keys into the streaming data to enable subsequent data mining to be accomplished on a less powerful computing device.

    摘要: A bipolar electrostatic chuck containing apparatus, and a concomitant method, for balancing an electrostatic force that the bipolar electrostatic chuck imparts upon a workpiece. More specifically, the bipolar electrostatic chuck contains a chuck body having a pair of electrodes embedded therein, a primary power supply and an offset power supply. Each electrode within the bipolar electrostatic chuck is respectively connected to a terminal on the primary power. Based upon a voltage produced by the primary power supply and a bias voltage of the workpiece, an offset voltage is applied by the offset power supply to one of the terminals, thus balancing the electrostatic force applied to the workpiece.
