Merge two VI, a pass-through to another VI

Hello

It's more about asking a suggestion to ask the solution to a problem.

At the moment I have two independent VI

1st VI - acquire impulses in real-time, filter it, detect the peaks, take tiem difference between peaks, use this information to calculate a certain number of parameters that change in real time according to changes in pulse signal.

2nd VI - select a rhythm of breathing and guide the user using the fornt Panel bars and the audio output following a rountine.

Now I want to combine the two VI as the 1st VI processes the data and sends information to the 2nd VI. The loop runs a second apart, so data are discharged into a table in half a second.

The second VI will be, according to the data obtained form VI 1, either use these data to change the front bar and audio frequencyto guide user or it can use its own values.

The second VI will take the data from the 1st VI all a few seconds and then its own tasks of façade.

The idea is to create a system of biofeedback that guide the user (2nd VI) based on signals physiological user (calculated in 1st VI)

I have read the information on the parallel loops and how data is transferred between them. I have not yet implemented any of these and have little time in my project wish to get some suggestions.

I would like two front panels for that data collection and prcessing graphics are displayed on 1st FP and 2 user guidance. I do not know it can eb done using the 2nd VI as void VI. but do not know if this is the best way both of them to communicate.

Any suggestion is welcome.

Thank you

JAS

Preferably not. If possible, wire data directly in the Subvi if the connector pane. Since you want to that they act independently, I suggest using queues for each type of data and/or group. Queues can be referenced by its name rather than wiring directly to the Subvi.

  • WRV200 VPN pass through limits

    We use a Cisco Small Business WRV200 to allow guests to our office to access the public internet, regardless of our corporate network environment. We regularly invited several visit of a company and generally these users connect to their company via a local VPN client. I noticed that after about 5 users activate successfully their VPN clients that no one else can connect to any other VPN tunnels. Internet connectivity still works when these 5 tunnels are active, but no other users can create a VPN tunnel after this point. Again, these are all movers or Pass through tunnels behind the WRV200 in one single environment NAT. is there a limit on vpn pass through or leaving behind this device connections and if so can it be changed? I expect a resolution of firmware to this problem, but it seems that it is only a single firmware version for this device. If this unit has an immutable limit, can then someone propose another product, Cisco Small Business wireless which has no limit of transmission?

    Thank you...

    If the NAT - T is enabled on clients and VPN gateways, there should be no problem. Otherwise, if two IPsec clients behind WRV200 are trying to connect to the same remote gateway without NAT - T active, 2 IPsec sessions could clash between them.

  • Merge two favorite files - one of the former without losing new entries

    I'm trying to move the Favorites from one computer to another, without losing the favorites that have been added to the second computer, which can ONLY be the first. Once I have export favorites from the first computer on a port USB, import replace simply all the Favorites on the second computer folder or it will ask me if I want to record a new one to the old double the second favorite of the computer file (like when you save jpg files).

    Or is there another way to "merge" two folders, as visually opening upward both files and selecting what to switch to the hand...

    Thanx

    PS - am moving to Vista on a Windows 7 computer. as well as the synchronization of the two win 7 after that.

    Hi Maril,

    Thanks for posting your question in the Microsoft Community Forums.

    Based on the information, you find out when you try to move the Favorites from one computer to another, if the existing Favorites in the second computer will be deleted.

    Usually, when you import bookmarks to another computer, it will not replace the already existing bookmarks on the second computer.

    However, to be on the safer side, you can take a backup of the bookmarks on the second computer to another folder or another location.  Try favorites of the importation of the first computer to the second computer, check if you are able to access to existing favorites as well as any.

    If this is not the case, try adding the Favorites of the backup location to imported Favorites and check if it helps.

    You can also copy favorites from the second computer to the first computer and save it in a new folder. Try to create another folder containing the computer the two first and second Favorites and then import the Favorites from this folder to the second computer.

    For more information, see the article:

    Add, view, and organize Favorites

    Hope the helps of information.

  • Code to merge two PDF files of the scanned book: one of the odd pages and the other pages even.

    I'm looking for an effective way merge two PDF files: one with all the odd pages scanned a book, one with all even-numbered pages. This question has been posted several times in many different forums.  I am unable to get the Javascript code that is given in the following forum to work.  https://forums.adobe.com/thread/286654.  Generally, the responses to this question are not useful for me because 1) they provide instructions that apply to an older version of Adobe (I use Adobe Acrobat Pro DC), or 2) they involve software purchase that I found to be ineffective. One post step by step to complete code that can do bonded labor and be registered as a custom through the command Wizard command (see the post from 11:27 January 13, 2016 to https://forums.adobe.com/thread/2063936, for an example of a good response to a different question) would be much appreciated.  Thank you, Carl

    You can use a large part of the script that was posted in the other thread and create a personalized out of it. In fact, it makes the script easier to understand, because all the "stuff" that is about adding menus and elevate the rights of scripts is no longer necessary.

    See here for instructions on how to create a custom in Acrobat DC command:

    Create orders customized in Adobe Acrobat DC Pro - KHKonsulting LLC

    Instead of the sample code of the blog post, you would use this (which is really just a copy & paste of the original script):

        // create an array to use as the rect parameter in the browse for field
    
        var arRect = new Array();
        arRect[0] = 0;
        arRect[1] = 0;
        arRect[2] = 0;
        arRect[3] = 0;
    
        // create a non-visible form field to use as a browse for field
        var f = this.addField("txtFilename", "text", this.numPages - 1, arRect);
    
        f.delay = true;
        f.fileSelect = true;
        f.delay = false;
    
        // user prompted to select file to collate the open document with
        app.alert("Select the PDF file to merge with")
    
        // open the browse for dialog
        f.browseForFileToSubmit();
        var evenDocPath = f.value;
    
        var q = this.numPages;
    
        var t = app.thermometer;
        t.duration = q;
        t.begin();
    
        // insert pages from selected document into open document
        for (var i = 0; i < q; i++) {
            var j = i * 2;
            this.insertPages(j, evenDocPath, i);
            t.value = i;
            t.text = 'Inserting page ' + (i + 1);
        }
        t.end();
    
        // remove unused field
        this.removeField("txtFilename");
    

    Given the instructions in my blog, you should be able to create this custom command and run it. To run it, the important part is that you load the 'weird' part of the document first, then launch the custom command and then select the item "same" document.

  • Merge two of the same photo with applied different exposures

    I have a picture that I copied a couple of times and imported to LR. I've adjusted to the exposure of the sky in a single copy and then in the foreground in another. How to merge two photos to make the sky a as well as the first plan of the other?

    Combination of two images requires another program like Photoshop, Photoshop Elements, or some other software pixel editing program. If you have two different exposures to different contexts and use Lightroom 6 or Lightroom CC you have an option to use Photomerge and choose merge to HDR. But the part that there is no way to combine the two images using only Lightroom.

  • How to merge objects of an RPD in an another RPD in OBIEE.

    Hi all,

    I am new user of OBIEE. I was given a task to merge two deposits. I tried many things, but could not do so. I went through many forums and discussions to find the relevant answer but couldn't find anything. In fact, my requirement is to merge the two repositories. For example, consider two repositories: SPR1 and rpd2 respectively. Two repositories has its own set of objects. I want just all rpd2 objects to merge with SPR1 as SPR1. Is this possible? If it is possible... Please, someone let me know the steps to do.

    Thanks in advance
    Stephanie

    What you need to do is a merger without a common parent. Create an empty RPD as the orginal and SPR1 and rpd2 are current and updated RPD to update the. Open one of the rpds in offline and use the Merge Wizard from the repository

  • Does anyone know how to merge two workseets number for printing?

    How can I combine two spreadsheets in numbers for printing?

    Hi jj,

    I assume that you mean that you have a single document, which contains two worksheets, and that each sheet contains one table (only?).

    What do you mean by "merge two (booklets)?

    You mean you wan to place Tables of two leaves on a single sheet (this sheet would contain then both tables).

    Or do you mean you want to place all data on the two tables into a single table on one sheet?

    Or do you mean something different to both of these descriptions?

  • Apple TV 4 Audio pass through

    Hi-

    My current setup is: 4 AppleTV via HDMI-> Onkyo HT-R990 7.1THX via HDMI-> Samsung Smart TV 60 inch LED. The TV speakers are turned off and that all the sound elements through my 7.1 System.

    My question is about how to disable the audio decoding on the Apple TV. Can the Apple TV 4 simply intercommunication audio without decoding? That's why my receiver will decode and choose the best audio configuration for content.

    Having a transmission option is fairly common on most devices such as Blu - Ray players. What's not an option on the Apple TV? I know by selecting "Auto" on the Apple TV, it will send the PCM signal. Why would I have DD or PCM if the content is DTS Master for example? It makes no sense to me.

    I think I have a 'Pass-through' option would satisfy loyal people optical cable and move is a real audio visual component of the Apple TV.

    Does anyone know how this can be done? Your help is greatly appreciated. See you soon!

    It can normally send PCM for music/video stereo and support the bitstream DD for 5.1, ATV 4 7.1 - I assumed AppleTV 4 this but have moved for a few months and don't have not connected my AV Pioneer amp just for the Samsung TV.

    AppleTV does not support DTS officially, certainly not for the content of the iTunes store is not an option, but I don't know about 3rd party applications that could broadcast "other videos" of local shares.

    Slide show projects cannot be merged.

    If you visit both attractions like a video, you can add the two points of view in iMovie and display a merged video.

    Otherwise, duplicate a slide show and add photos of the second presentation to the other.

  • using PostDelayedCall how to get the value passed through void * callbackData?

    Can someone tell me how to get the data passed through void * callbackData?

    The following code, panel_ptr has the right address but still contains zero.

    void CVICALLBACK value_changed (void * callbackData)
    {
    int * panel_ptr;
     
    panel_ptr = callbackData;
    calculate_new_value (* panel_ptr);
    }

    int sign;

    Panel = 2;

    PostDelayedCall (value_changed & Panel, 0.2);

    The problem is using the callbackData parameter if it is a pointer, it must be a pointer to something which is still topical at the moment that the callback executes. That is to say, you cannot pass the pointer to a local variable in callbackData as when the callback executes the pointer is no longer valid. You can switch from its value, instead, in this way:

    ... SomeFunction)

    {

    int sign;

    ...

    Panel = 2;

    PostDelayedCall (value_changed, (void *) Panel, 0.2);

    ...

    }

    void CVICALLBACK value_changed (void * callbackData)
    {
    int panel_ptr;
     
    panel_ptr = (int) callbackData;

    calculate_new_value (panel_ptr);

    return;
    }

    There are many discussions on the forums on callbackData parameter that you might want to read.
