| 20090178025 | GRAPHICAL PROGRAMMING ENVIRONMENT WITH FIRST MODEL OF COMPUTATION THAT INCLUDES A STRUCTURE SUPPORTING SECOND MODEL OF COMPUTATION - System and method for creating a graphical program that uses multiple models of computation (MoC). A first plurality of graphical program elements is assembled in a graphical program in response to first input, where the assembled first plurality of graphical program elements have a first MoC. A structure is displayed in the graphical program indicating use of a second MoC for graphical program elements comprised within the interior of the structure. A second plurality of graphical program elements is assembled within the structure in response to second input, where the assembled second plurality of graphical program elements have the second MoC. The graphical program is executable to perform a function, for example, by executing the assembled first plurality of graphical program elements in accordance with the first model of computation, and executing the assembled second plurality of graphical program elements in accordance with the second model of computation. | 07-09-2009 |
| 20090204937 | Conversion of a First Executable Diagram Having Interconnected Nodes to a Second Executable Diagram Using an Intermediate XML Representation - A system and method for programmatically generating a graphical program in response to state diagram information. The state diagram information may specify a plurality of states and state transitions, wherein each state transition specifies a transition from a first state to a second state. A graphical program generation program (GPG program), may receive the state diagram information and automatically, i.e., programmatically, generate a graphical program (or graphical program portion) based on the state diagram information. The GPG program may programmatically include graphical source code in a block diagram of the graphical program, which may serve as a framework of the states specified by the state diagram information and the state transitions among the states. The graphical source code framework automatically generated by the GPG program may include various “placeholders” or “containers” enabling the user to easily fill in the graphical program with source code that specifies execution instructions for each state and Boolean conditions for each state transition. The specific graphical source code that is automatically generated may depend on programming features supported by a particular graphical programming development environment with which the graphical program is associated. Examples of generating graphical source code for the LabVIEW graphical programming development environment are included. In one embodiment, the graphical program may be dynamically (programmatically) updated as the state diagram is being interactively constructed by the user. I.e., as the user performs various actions in a state diagram editor, such as adding or deleting states, adding or deleting transitions, etc., the corresponding graphical program may be dynamically (programmatically) updated to reflect the change. | 08-13-2009 |

| 20110321006 | Configuring a State Diagram with Graphical Source Code - A system and method for configuring a state diagram with graphical source code is described. The state diagram may be created in response to user input. The state diagram may include a plurality of state icons and a plurality of connector elements interconnecting the state icons, where the state icons represent a plurality of states and wherein the connector elements represent transitions between the states. Graphical source code may be associated with one or more of the state icons. | 12-29-2011 |

| 20080263512 | Statechart Development Environment with Embedded Graphical Data Flow Code Editor - One embodiment of the invention comprises a system and method enabling a guard condition for a statechart to be defined using graphical data flow code. Another embodiment of the invention comprises a system and method enabling an action for a statechart to be defined using graphical data flow code. The statechart may be created in response to user input, e.g., user input to a statechart development environment that includes a graphical statechart editor. The graphical data flow code that defines the guard condition or the action may be created in response to user input to a graphical data flow code editor. In some embodiments the graphical data flow code editor may be integrated with or embedded in the graphical statechart editor. | 10-23-2008 |
| 20080263513 | Event Firing Node for Asynchronously Passing Events from a Graphical Data Flow Program to a Statechart - A system and method for creating a graphical program operable to asynchronously pass one or more trigger events to a statechart. The graphical program may include a first node which is operable to asynchronously send one or more trigger events to a statechart. For example, in some embodiments the first node may be operable to place the one or more trigger events in an event queue associated with the statechart. The statechart may receive and process events from the event queue asynchronously with respect to when the events are placed in the event queue. | 10-23-2008 |
| 20080263515 | Automatically Generating a Graphical Data Flow Program from a Statechart - A system and method for automatically generating a graphical data flow program from a statechart are disclosed. The statechart may be created in a graphical manner in response to user input, e.g., in response to the user arranging state icons on a display and creating interconnections representing transitions among the respective states. The statechart may include at least one hierarchical state, where each hierarchical state includes one or more sub-states. A graphical data flow program may be automatically generated from the statechart. The graphical data flow program may include a plurality of interconnected nodes that visually indicate functionality of the graphical data flow program, where connections among the nodes visually indicate data flow among the nodes. The graphical data flow program may be executable to implement the functionality of the statechart. | 10-23-2008 |

The statechart may be created in a graphical manner in response to user input and displayed on a display. A graphical user interface enabling a user to select from a plurality of event modes for the statechart may be displayed. The plurality of event modes may include both a synchronous mode and an asynchronous mode. The statechart may be configured to receive events from an external program either synchronously or asynchronously, depending on which event mode the user selects. | 10-23-2008 |
