  • Methods and apparatus to generate and display trends associated with a process control system
    Patent number: 11922546
    Abstract: Methods and apparatus to generate and display trends associated with a process control system are disclosed. An example apparatus includes memory, machine readable instructions, and processor circuitry to execute the instructions to generate a first graphical user interface. The first graphical user interface to include a graphical representation of a component in a process control system. The processor circuitry to generate a second graphical user interface. The second graphical user interface to include a chart region with a trend represented therein. The trend indicative of values of a process parameter of the process control system over a period of time. The processor circuitry to automatically generate the trend in the chart region in response to a graphical element being dragged and dropped from the first graphical user interface to the second graphical user interface.
    Type: Grant

  • Generation of link node routing graph using a straight skeleton algorithm
    Patent number: 9841285
    Abstract: A processor identifies a navigable space. The processor generates a polygon from the navigable space. The processor calculates skeleton lines from the polygon using a topological algorithm. The processor removes a subset of skeleton lines leaving one or more center segments. The processor generates a routing graph from the center segments.
