  • Patent number: 7225193
    Abstract: A method and apparatus that processes time series, event and/or activity data of a process according to a data structure is disclosed. The data structure defines one or more activities that frame the time series, event and/or activity data. Each activity and each event has one or more attributes. Each attribute has a value. At least one of the attributes defines an interval of the activity by start and end times. Another attribute includes a time varying parameter that represents the time series data. Another attribute defines a time stamp of an event. The time varying parameter is linked to a device that produces the time series data when the process is run. The time series, event and/or activity data is collected and processed according to the data structure for storage in and/or retrieval from a memory.

  • Patent number: 5751613
    Abstract: There is provided a process control system having a display program that permits an program designer to create and edit dynamic picture objects in a persistent heap and save the heap to a storage medium. The display program rapidly reads the dynamic picture objects from the storage medium and invokes the objects for viewing on the system's interactive display. When the persistent heap is subsequently read from the storage medium by an operator, the dynamic picture objects stored in the heap do not need to be instantiated and, thus, invocation of the objects is accelerated and optimized. Accordingly, the persistent heap greatly improves the speed in which picture objects can be read from the storage medium, processed by the display program and called-up to the interactive display.
