## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to methods and systems for developing strategies for use in controllers and storage media for storing instructions which effectuate the methods.
2. Background Art
It is common to analyze and monitor data collected by electronics during a manufacturing process or a part-quality testing process (i.e., “process data”). This typically involves acquiring measurement data from one or more sensors, numerically transforming the measurement data, and comparing the transferred data against limits to check for compliance to an established norm. This is all done within an embedded controller device and is visually presented on a desktop PC or operator panel HMI (i.e., human-machine interface) PC.
The computer code that performs the data analysis and monitoring during the process is often called a “strategy.” The most widely employed approach to strategy development is hand-written computer code such as Matlab, C, C++, Labview, or Visual Basic. Solutions using this approach are usually fixed in structure and are parameter-driven for minor adjustments to the strategy. Major strategy changes must be made by an experienced software programmer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
In general, the present invention involves a method and system for developing a strategy for use in a controller and storage medium for storing instructions which effectuate the method. Computer visual interactive techniques and a heuristic approach are applied to data analysis and monitoring program development.
The unique features of at least one embodiment of the present invention include the following:

    
    
        Graphics are used to “program” the strategy by using a mouse along with accurate metaphors of strategy objects; the goal is: “what you see is what you get”;
        Changes made to a strategy are visualized immediately on the screen; no need to run the strategy on the embedded controller; this allows a strategy developer to work while the manufacturing or testing process is running;
        A database of strategy examples is available for experimenting with data and strategies; and
        A database of all manufacturing quality data collected is available for experimentation and to perform machine-learning activities.
    
    


In general, and as described in detail herein, in at least one embodiment of the present invention strategy development eliminates computer programming by offering a computer graphic approach. In this approach the user is presented with a blank 2-dimensional graph on the computer screen along with X and Y axes. Using available toolbars and palettes, the user drags appropriate graphic objects into the graph. Each object represents an operation to perform for data analysis or monitoring such as: data acquisition, data transformation or operating limits.
Once the user has developed an initial strategy, he next chooses to visualize the data by either A) acquiring data immediately or B) grabbing data previously acquired and stored in a database. When the data is shown in the graph, all other graph objects respond instantly by updating their interdependencies and visually reflecting their new states.
The user continues to refine the strategy by downloading it to the embedded controller and testing its effectiveness and debugging the strategy.
There are two different types of databases used to assist strategy development. One is used to store all process data acquired and the evaluation results of every strategy implemented in the embedded controller. The other database is used for experimentation purposes. It is organized by the user into a collection of strategy objects or complete strategies.
In general and by way of background, a monitor resource represents a set of instructions to implement a monitoring strategy. During firmware run time, it is represented by a C++ object with the following characteristics:

    
    
        It inherits from Resource type. As it turns out, there are many other types of resources in the firmware.
        It has a particular interface of functional methods to do things specific to that type of resource.
        It has a collection of properties that define how the monitor resource should behave overall.
        It contains a Window type resource called the “base window.” This base window, in turn, contains multiple windows among other monitor entities.
    
    


A monitor resource contains multiple “monitoring entities,” which are just other types of resources that do very specific things. The different major types of monitoring entities are:

    
    
        Window
        Function
        Limit
        Marker

There are several sub-types underneath each of the above major types.

    
    


A monitor resource has a persistent form embodied as an XML element, which is typically contained within a larger program. The XML element stores all of the properties of the monitoring entities contained within the monitoring resource.
Referring now to the drawing figures, FIG. 1 is a schematic of monitor view architecture which provides an overview of the user interface side of monitoring. Starting with the monitor resource contents panel (upper-left corner) and working clockwise:

    
    
        (1) The monitor resource contents displays a tree-like list of monitoring entities that comprise the monitor resource being viewed. Here the user may add, change, and remove entities and see the last results of a strategy change or simply the last part run of the monitor resource in the firmware. This panel is always synchronized with what is displayed in the graph; entities are added to the monitor resource contents panel when they show up in the graph. When entities are added in the graph, then they show up in the contents panel.
        (2) Monitoring data may be exported to various file formats including comma-separated-value (CVS) text files and Microsoft Excel compatible files. Monitoring data may also be imported from similar file formats.
        (3) The monitoring view reads monitoring results and other information when displaying “live” information. For example, during part runs, the monitoring data can appear to update in real-time.
        (4) The monitoring strategy is stored in the larger context of a program (program.xml) that is transferred to the firmware device for it to execute the program. The monitoring view reads the strategy from the program and writes the strategy back when changes are made.
        (5) In order for the monitoring view to “know” what monitoring entities are available for insertion into the monitor resource and further to know what properties a monitoring entity has, it relies on an XML file called “resources.xml.”
        (6) The “what-if” and interactive nature of the monitoring view is made possible by the PRO Monitoring Engine or “engine.” The engine is an exact duplicate of the computer code normally running on the firmware to carry out the monitoring strategy. When the user makes changes to the monitoring resource, the view recalculates the effect or results of the changes by passing the monitoring resource through the engine. The engine runs through the same calculations that the firmware would perform on the monitor resource and returns the results back to the monitor view. The monitor view is thus able to display the results instantly after a strategy change is made.
        (7) The system database contains all the collected information of past part runs monitoring resources. For each part run, the system database stores both a snapshot of the monitoring strategy used and the results from applying the strategy to measured data during the run.
        (8) The example database contains various configurations of monitor resources that the user has decided to keep around for experimentation or productivity purposes. A configuration of a monitor resource can be as simple as a single acquired curve to a complete monitoring strategy. A configuration can also contain individual monitoring entities such as functions, limits, and markers. The example database is used primarily by the Examples Panel, which interacts with the monitoring view.
    
    


FIG. 2 is a schematic of a monitor view which illustrates interaction with a monitoring strategy. This diagram describes monitor view and everything that interacts with it. The monitor view has three major modes of operation: edit, live, and data recall. These modes are described in other figures.
Starting with the Window Function Palette (upper-left corner) and working clockwise:

    
    
        (1) The Window Function Palette and Window Operations Palette represent monitoring entities. The user can drag an item (represented as an icon) from one of the palettes into the graph in which case this adds the corresponding entity to the monitor resource. As the user drags the icon into the graph, the icon changes into a ghosted visual representation of the monitoring entity once it is dragged over the graph area. This adds to the intuitiveness of working graphically with the monitor resource.
        (2) Various tool bars are available for commands involving the monitoring view, the monitoring resource, or monitoring entities.
        (3) An optional legend panel shown directly in the graph (or near the graph) provides a visual key to the monitoring entities shown in the graph.
        (4) Various form and wizard dialog windows complement the monitor view.
        (5) The monitoring view interacts fully with the system clipboard by allowing monitoring entities to be cut, copied, and pasted via the clipboard.
        (6) The Snapshot dialog lets the user take the current visual representation of what is seen in the view and store it as a bitmap. Using a wizard approach, the user can store the bitmap as a file or send it somewhere via email.
        (7) Curve data (including any other monitor entity) can be pasted directly into monitor view via the clipboard.
        (8) Monitoring entities can be dragged visually and dropped into the view from another monitoring view or monitoring resource contents panel.
        (9) Among other methods, the monitoring view can be launched directly from the examples panel. This allows the user to develop example strategies separate from any programs running on the firmware.
        (10) The user can create multiple “zooms” of the monitor resource. Each zoom focuses on a particular monitor window entity within the monitor resource. A zoom only shows monitor entities for a particular monitor window.
    
    


FIG. 3 are schematic views of a legend panel and a monitor panel; the legend panel may appear in the monitor view and the monitor panel is an alternate view of a monitoring strategy and represents all that can be seen in the monitor view. From left to right:

    
    
        (1) The graph in the monitor view has a legend. This legend describes every monitoring entity present directly underneath the monitoring window in which the user is zoomed into. If certain entities are not visible because of the zoom settings, then at least the user knows what entities exist by referring to the legend.
        (2) There is an optional panel called the Monitor Panel that shows a tree-like list of the contents in a monitor resource. Using this panel the user can see the entire contents of a monitor resource.
    
    


FIG. 4 is a schematic of a monitor view in an edit mode which is entered when a user begins to change a strategy; as in FIGS. 1 and 5 “PRO” represents an embedded controller and “Monitor Resource” represents a resource or software object inside firmware of the embedded controller. When the monitor view is in edit mode, the user can interact with the graph by adding, changing, or removing monitoring entitles such as functions, limits, and markers. As changes are made to the monitoring strategy, the PRO monitoring engine is utilized to recalculate the expected results of the strategy. Monitoring entities can be added by dragging items from the monitoring palettes, using the pull down menus, using the right-click menus, and dragging items from the examples database.
FIG. 5 is a schematic of a monitor view in “live mode” which is the mode for seeing what is correctly happening with the monitor strategy. The live mode displays the monitoring strategy along with whatever results have been calculated by the firmware. The results come from the system database and from live data feeds from the monitor resource running in the firmware. In the live mode, there is an option to see real-time curve data as it is being acquired by the firmware. In this situation the user sees the acquired curve being drawn continuously as the data is measured.
FIG. 6 is a schematic view of an examples panel which is useful for doing “what if” experimentation with monitoring strategies. The examples panel represents a collection of monitoring entitles organized by the user for the sake of applying example strategies and results to existing or new strategies in development. This panel allows for easy dragging and dropping of entities from and to the monitoring view, the monitoring contents panel, and the Window Legend panel.
FIG. 7 is a schematic of a recall view which is a variation of the monitor view and is used to recall past runs of a strategy; the recall view allows a user to analyze past data and modify the current strategy based on past data (i.e., a heuristic approach). The recall view shows strategies and results that have been collected in past runs of monitoring resources. It allows for filtering, searching, and easy traversal of sets of monitoring data. A Preview panel provides a bird's eye view of all the monitors in a query set. Starting with the Preview panel(left side) and working clockwise:

    
    
        (1) The Preview panel shows a scrollable list of monitor previews. A monitor preview is a small version of what the monitor resource looks like in the graph when selected and viewed. These are also called thumbnails or thumbnail views.
        (2) Toolbars are available for zoom operations and recall specific operations (not shown).
        (3) There are several form and wizard dialog windows that apply to this view:
        
            a. Query Settings dialog—allows user to specify the set of monitors to recall.
            b. Graph properties dialog—allows user to change graph colors, background fill, grid pattern, and other characteristics of graph presentation.
            c. Print dialog—allows user to print the graph.
            d. Export dialog—allows user to export data in the graph to a text file or Microsoft Excel compatible file.
            e. Make Example dialog—allows user to turn the recalled monitor into an example monitor resource for strategy development use later on.
            f. Monitor resource entities can be copied to the clipboard for use elsewhere.
            g. Use as Taught Information dialog—the user can quickly use the recalled monitor to teach the current strategy related to the recalled monitor resource.
        
        
        (4) The Snapshot dialog lets the user take the current visual representation of what seen in the view and store it as a bitmap. Using a wizard approach, the user can store the bitmap as a file or send it somewhere via email.
    
    


FIG. 8 is a schematic of a query settings dialog box which allows the user to select what is recalled from a database. The query settings dialog allows the user to narrow down the recalled set of monitors. Starting with the top field:

    
    
        (1) “Only monitors in program” limits the query set to a particular part program.
        (2) “Only monitors in macro” limits the query set to a particular macro name.
        (3) “Specific monitors” limits the query set to particular monitor resources.
        (4) The user can further restrict the query set based on evaluation status OK (okay) or Nok (not okay).
        (5) A button is provided to enter an “Advanced Query Settings” dialog (not shown) where the user can enter an SQL expression to define the query set.
    
    


FIG. 9 are schematic views of a “Teach Wizard” from the recall view; the “wizard” approach is used to automatically update limits in the current strategy based on past runs of the strategy. The Teach Wizard provides a method of teaching a monitor resource from past collected information contained in the system database.
There are two basic approaches employed here: teaching from a recent sequence of runs or teaching from particular monitoring examples in the examples database. Teaching from a recent sequence of runs requires two parameters: “Last N runs” and “Skip every M runs”. This means it will go back as far as N runs and use every Mth run from that point forward to the most recent run when teaching the monitor resource.
FIG. 10 are schematic views of export and import dialog boxes which allow the export of data from any of the monitoring views and the import of data into the strategy for reference purposes or for “what if” analysis, respectively. The first dialog window, Export Monitor Data, is responsible for exporting graph curve data to a specific file type. To perform the export, the user first selects the file type, the location where the file is to be stored, and chooses the “Export” button to begin the export process.
The second dialog window, Import Monitor Data, is responsible for importing graph curve data from a file. To perform the import, the user first enters the location of the file to import. Next the user chooses the “Import” button to begin the import process.
FIGS. 11 and 12 are block diagram flow charts which illustrate a few basic states of processing when a monitoring resource “runs” inside embedded firmware. As shown in FIG. 11, there are two primary states of a monitor resource during firmware operation: Active and inactive. Upon entering the Active state, the monitor resource is in the “Acquire” sub-state. Once the acquisition state is finished as a result of a trigger condition or by an external command, the monitor enters the “Hold” sub-state. If the monitor is deactivated during the Acquire sub-state then it proceeds immediately to the “Analyze” sub-state. The monitor goes into the “Analyze” sub-state from the “Hold” sub-state when the resource becomes deactivated or an external command is given forcing the monitor to analyze its contents. In the “Analyze” state the monitor evaluates each window contained in the monitor resource. Once the analysis is done, the monitor resource enters the “inactive” state.
FIG. 12 describes the containment relationship of the monitor resource and its child window resources. More specifically, a monitor resource contains a “base window” that can contain any number of other windows. Each window can also contain other windows and so on.
FIG. 13 is a series of graphs within a window which illustrate a data layering concept of a monitoring strategy windowing method constructed in accordance with one embodiment of the present invention. The processing of window data proceeds from parent to child where a parent window contains the “input” data that is processed further by its contained child windows. This figure shows an example involving three windows(1, 2, 3). Window 1 is the parent window of 2, which the parent window of 3. When window 1 is processed, a set of data is produced as a result. Next window 2 is processed by “clipping” the data from window 1, applying it to one or more functions and collecting the results of the functions to serve a window 2's data. Last, window 3 is processed by taking the data of window 2 produced in the previous step, clipping it and passing it into window 3's functions producing data for window 3.
FIG. 14 is a schematic view of a window example showing various components including sub-windows, limits, markers and annotations constructed in accordance with an embodiment of the present invention. A window contains the following types of monitoring entities:

    
    
        Other “sub” windows
        Functions
        Limits
        Markers
        Annotations
    
    


Referring now to FIG. 17, a window is evaluated as follows:

    
    
        1. The window's parent data is clipped to a box defined by the window. Marker-type entities in the window's parent are used to place the box in the coordinate space of the parent.
        2. This clipped data is supplied as input to the functions of the window. These functions usually produce “result” data.
        3. The result data is compared against limit-type monitoring entities.
        4. The result data is used to update marker-type monitoring entities. These markers are potentially used by child windows to place their clipping boxes.
    
    


FIG. 15 is a graph of force vs. distance together with a marker, origin and anchor points and a data clipping box which collectively illustrate an anchoring method for window data layering inside a strategy in accordance with an embodiment of the present invention. FIG. 15 describes how data clipping works. A child window defines the dimensions of a box (represented with dashed lines) within the parent window coordinate space, e.g. width and height of box. The child window also specifies two marker entities (an X marker and a Y marker) in the parent to use for anchoring the clipping box.
The user can easily define the anchor point by dragging (with the mouse) the anchor icon to any intersection of markers in the parent graph. By default, the X and Y axes are also used as marker entities.
The child window also defines an origin point relative to the anchor point. The origin point defines where coordinates 0, 0 in the child window lie within the parent window.
The user can easily define the origin point by dragging (with the mouse) it to any place in the parent window.
FIGS. 16a and 16b are schematic views of lists of graphical icons or representations, their names and descriptions which provide the building blocks for strategies that can be dragged into the monitoring view or inserted into the monitor list-based panel representation as illustrated in FIG. 2. FIGS. 16a and 16b provide a survey of the monitor entities available in the pallette for use in monitor resources.
While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
