How to effectively create a single waveform based on data from two other waveforms?

I have a table 1 d of waveform with size = 4 which contain data of voltage potentiometer "gross".  I need to handle index 0 & 1 waveform data using the formula below to calculate a single waveform of angle data.   I need to do the same for the 2 & 3 index because it is a redundant circuit.   I was hoping that the formula node can operate on whole berries and even if it may take a table as input, it asks me to the array index in the formula so that it becomes a scalar value.

As the formula is quite complex, I would like to keep as text, but run automatically on each point of the two input tables.  This math is done online with pulling data from a data acquisition and so I need it to be as effective as possible, so that I do not spend too much time on it and likely to overflow the buffer DAQ.

The naïve solution would be to wrap nodes formulas with curls, but I don't know if it is this is an effective way to do it.  I'd like suggestions on how best to address this issue.

Thank you!

Here's how I would do it with no formula requires knots or loops:

If you want to use the formula node, you can then run a loop inside each node formula while the index of you through the berries.  The difference in performance between the nodes of the formulas and graphic approach expected to be negligible.  Note that my approach assumes that the table sizes are the same.  You can also create a sub VI to contain the math so you don't have to maintain two copies of the same piece of code.

  • How to fill a field read-only based on selections from 2 DDlists?

    Follow-up question:

    http://forums.Adobe.com/message/2417876#2417876

    I have 2 drop-down lists.  'Department' and 'unit '.

    The selection in DDlist 'Department' creates a single list in DDlist 'unit '.

    I select the appropriate of these two DDlists elements.

    When I do this, I want the text read-only 'NameOnIDBadge' field is filled with a predefined entry.

    Example:

    In DDlist "Department", select the item «Finance & Administration»

    In DDlist 'Unit', select the 'Food Service' item in the list that appears

    THEN:

    In the text field read-only 'NameOnIDBadge' of the following built-in read-only text appears: "contract food serv.»

    (Thanks to Paul, I already know how to do selection in DDlist 'Department' affect the selection list in DDlist 'Unit')

    "but I don't know how to make the choice of these two DDlists to create a new entry in a text field).

    I have attached a mock-up of the file that I work with...

    If ((firstDDList.rawValue="Whatever") & (secondDDList.rawValue = 'Whatever'))

    yourTextBox.rawValue = "the text on the right"

    This code would go under the second output of DDList event, replace the code I put in there to add the control to the first DDList

  • How can I create a filter to remove only "junk" from the server?

    One of my email accounts is an important customer. I manage their online customer service. Normally our protocol must always leave all messages on the server, so that one Thunderbird account, I never put delete messages on the server.

    But the account has recently started a lot of unwanted messages. Thunderbird is doing a remarkable job to those tagging and placing them in the folder junk e-mail for this account. I would like to create a filter that could remove them from the server, preferably more than "x" days old so I could monitor activity to ensure that no important messages are removed.

    I noticed that in "Filters" I can create a custom header of my choice filter, but am unable to create what I want which is:
    -After the mail is marked as junk by Thunderbird to delete messages from the server, if they are older than "X" days (my choice of 'X').
    -not to delete all messages in the server for this account

    Try:

    • Right-click the junk e-mail folder and select "Properties".
    • Click on ' retention policy tab
    • He chooses to "use my account settings."
    • Uncheck this option for other options.
    • Select: for example: delete messages more than x days.
    • Click OK to save the changes.
    • Close and then restart Thunderbird

    Hi, a beginner full here.  I'm looking to create a 1 button that can copy data from a filled on adobe form, essentially the text fields and checked radio buttons, then have another 2 button that can Paste the copied data to another form, containing the same exact text fields, and radio buttons.

    Example:

    1. click on 'Copy' in formula 1

    2. click on 'Paste' in form 2

    3 fills in the data from form 1 to form 2

    No idea how to do this?

    Here is a simple example on how to do it. Let's say you want to copy the contents of the field 'name '. In the first form you change the button copy and add a MouseUp action with a command "Run a JavaScript", that has the following code:

    overall. Name = this.getField("Name").value;

    Then, the button stick in the other file, you create the same thing, but with this code:

    If (global.name) this.getField("Name").value = global.name;

    In general, you will need to use an AJAX call to the server

    It really depends on what the server returns as to how the information is easy to digest

    JQuery provides a simple interface, and returns information easy to use

    If you deal with things gets complicated XML according to namespace

    If you look at the raw XML data and it goes something like fred: name you will have questions requiring an implementation of SAX - JSON is simple if you don't get that even if (nothing too confusing here)

    If using an external data source JSON go if you have the choice

    As examples go - just look to the top of JQuery Ajax [JSON / XML] and you will get where you're going quickly

    SAX is MUCH harder because of the namespace - Dublin is the most common and same XML without namespace is not simple to handle, so avoid it if you can

  • How to effectively create message filters?

    Hello

    I have dozens of filters, just move messages to an appropriate folder, such as social networks, services, forums, mailing lists and so on.

    It's a pain to create a filter whenever a new unclassified message arrives. In addition, it takes a lot of time, 1 min or more to run all the filters on my Inbox.

    Is there a better way to do this? I wanted to say "messages like that will go in this folder" simply by dragging or so.

    Instead, I have to:

    1 copy 'from' address
    2. open the filters
    3. Select the appropriate folder filter
    4. scroll through the list of rules and add a new
    5. apply the filter to the Inbox

    If there is no better way, how can I suggest such an improvement? It seems that the IRC channels provide no help on this.

    Thank you.

  • How can I create a single action that hides several items at once?

    I create what I call a "video jukebox", and I would like to find an easier way to switch between videos, according to which the button is clicked. For example, I have 7 videos for viewers to choose.

    On the stage to animate are 7 buttons, each button corresponding to the appropriate video.

    I also added 7 videos of the scene (let's call them Video01.mp4, Video02.mp4, etc.).

    Press each key, I added the following to mousedown:

    SYM.$("Video01"). Hide();

    SYM.$("Video02"). Hide();

    SYM.$("Video03"). Hide();

    SYM.$("Video04"). Hide();

    SYM.$("Video05"). Hide();

    SYM.$("Video06"). Hide();

    SYM.$("Video07"). Hide();

    I have then change ' hide ' for 'show' according to which video I want to play when the viewer clicks the button and assign a mouseup action.

    I'm wondering 2 things:

    1. is there an action that allows you to hide all the videos with a single line of code, instead of repeating it several times (for each video)?

    2. can I assign a code to a transparent symbol I can superimpose each button so I can't open the actions for each of them? In other words, I would simply drag a symbol on the stage and have the code already attached to it, then all I have to do is change one or 2 lines instead of having to rewrite the entire thing every time.

    Thank you

    1 sym.$("video").hide (); allows you to hide all the video elements, then you can selectively show an individual video like sym.$("Vidoe01").show ();

    2 write a function in compositionReady as:

    sym.hideShowVideo = {function (name)}

    SYM.$("video"). Hide();

    SYM. $(Name). Show();

    }

    Call this function for each button in sym.hideShowVideo ("Video01");

  • How can I create a single delayed output (analog voltage) of a Trigger (analog voltage) input reference pulse?

    I am working with a combustion chamber and using a system of data acquisition (with the hardware OR SCB - 68) to read the pressure in the cylinder (such as analog voltage). I'm trying a pulse delayed, 1 millisecond to 5 volts of output once the pressure in the cylinder is high above 5 bar (which corresponds to an analogue voltage of 0.25 V). I would also like to record 30 ms samples before the trigger and 220 ms samples after the outbreak. The following image shows visually what I'm talking about.

    I created a LabVIEW VI (which is attached), but I keep running into 2 issues:

    1. When I run with samples finished after a period of time, I get error-200281which I don't quite understand.

    2. Using the Express VI 'Out of time' to keep time for the pulse I can not get a resolution of 1 millisecond, the pulse is not generated when I put the window between 0.003 and 0.004 seconds for high pulse (i.e. the resolution of 'Elapsed Time' seems to be too coarse).

    I'm a beginner to LabVIEW sorry if my questions are trivial or my VI makes no sense, but I was stuck on this during more than a week. Any help would be greatly appreciated!

    Thank you

    Morgen

    This isn't a good way to trigger a pulse.
    Use a trigger DAQmx to send the pulse when your acquired signal exceeds 250 mV you specified.

    See this for DAQmx trigger:

  • How can I create a single Inbox for mail unread?

    I have 6 email addresses which I access via Windows Live Mail

    How I put it so that there is only one folder which shows all messages unread all accounts?
    Bravo for assistance

    If it does not already show, there is an option called quick view. On mine, he showed at the top of my list of email account. If it does not show, go to VIEW, select FAST visualization, put a check mark in the seconds box and click SAVE.

    The decoder must also be verified. My top box is checked by default and gray where I even don't mess with it.

    Quick view should appear on top of your list of emails with a selection for all unread emails.

    I hope this helps. Bless you!

  • How can I create a new gradient based on the current fill color that I am applying it?

    I often need to add gradients to shapes that already exist and already have a fill color. I want to add a gradient that would be a mixture of the color that is already there and the black.  Gradients of new totally ignore what existed before. Is it possible to include the fill color that is already there in the slope?

    In fact, you can skip the step of swatch. You can drag the fill color directly from the toolbar at the appropriate end of the fitting band gradient in the gradient/panel palette; Then, apply the gradient. Be careful, though - you can end up creating a new unwanted color along the gradient stop.

    You can use a pre-fill adapter. The easiest way is to write a java class and package in a jar and deploy it in the xellerate/JavaTask directory. In this task, you can have an entry in the Users.Key or Users.User ID and then use the findUsers tcUserOperationsIntf api to search for that particular user and get all the fields you need her. Then, using if statements or any other comparison code, execute the logic you determine the user id in the target. Then return the new user as your output of your code. Create an adapter in the factory of pre-filled type adapters and use the code that you created. Then on the form for this workflow process, add a prepopulate field for the user ID and select your pre-fill adapter.
