  • Patent number: 6711506
    Abstract: A plurality of system checks on a turbine component inspection system are monitored, and an end user interface element to cause an inspection of a turbine component to commence is enabled only upon determining based on the monitored system checks that the inspection system is in a predetermined state of readiness, thereby ensuring each turbine component inspected is stimulated with thermal stimulus having the same characteristics. Further, a binary passed or failed indicator is displayed to unequivocally inform the operator whether a turbine component being inspected passed or failed the inspection. In a preferred embodiment, thermal images of a turbine component's response to applied thermal stimulus, as well as status of automatically launched quantitatively analyses on the turbine component's response to the applied thermal stimulus are also displayed.

  • 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.
