Is labview able to record the peak to peak value from an ECG wave automatically?

need some help here. i am a new user of labview and i do not know much about labview. i want to ask if labview is able to read and record an ECG waveform? if yes can someone teach me how is it done? thanx!!

How to get peak values from SM52?

Hello
I am trying to optimize my VMC since it has a high load compared to the hardware it runs on. To do that I need the peak values of those figures shown in SM52. Do any of you know how to get those?
I have NW 7, CRM 5.0 and SP13. All I get in SM52 is "Used/Allocated" with one exeption; the number of vmc containers and that show me this: "Minimum / peak / maximum number of VMs".
Thank you!
Best Regards, Linus Hellsing

Hello Jothivenkatesh M
Thank you for your answer. My problem, however, is that I need the maximum values of the other values.

To measure and hold the peak value of voltage while measuriong using an accelerometer

i would like to measure and hold the peak value of voltage while measuring using an accelerometer,when the voltage goes above certain range . also save highest 5 values.

You could have a shift register on your acquisition loop that is initialized to hold an array of 5 values. Start with all 5 element holding something less than the expected normal input value.
Now each time through the loop, test the new reading to see if it's greater than the minimum value in the 5-element array. If not just go on and repeat the loop.
If the new reading is greater than the minimum value in the 5-element array, append the new reading to the array, sort it in decending order and drop the last element (the old minimum value).
The array will hold the 5 greatest values and the max of the array will be the peak value.

Find out the peak position from graph

Hello All,,
Actually i want to run this algorithm real time,, to find out the peak position from graph ,, i need to generate the position automatically,,, firstly i try to use image processing by apply threshold followed by edge detection and the find out the center of each detected part. the drawpack of this procedure is that the obtained images are different and that lead to different threshold values,, so how can i directly find the position from the graph,,, here i attach the image and the graph of the image,,
thank you,,

Hello Klemen:
here i will explain in more details: the main objective of my work is to calculate velocity of small particle,, i perform my experiments by exposing the particle to 2 light pulses,, and i know the time between the two pulses,, so i need to know the distance to calculate the velocity,,, for that i apply correlation,,, the spot that appear in the correlation image is an indication of symmetry,,,so i should know the location of maximum intensity of each peak. The central peak (highest intensity) will be the reference (zero point) and the other peaks locations should be subtracted from the reference peak to determine the shift,,,
Here is the sequence of the process:
Acquiring raw image, correlation, position of central peak, shift calculation, velocity determination,,,,,
applying image processing is good idea in case of post processing condition,,, but in my case i need it real time, that mean if i need to apply image processing for calculation, i have to find out a universal criteria for threshold value that can be applied for all raw images,, from my experiments i didn't find specific criteria & i have to manually change the threshold value,,
If I choose the intensity (grey level) to be the criteria, then the small peaks (symmetry) will not take place,, because their intensity is very low compare to the central peak,,,
So the most reliable procedure is to directly find out the position of the two small peaks beside the central peak and save this values into an array and use it for calculation,,, I hope I am clearly explain my problem..
Thanks

Recording measured voltage and current values from LCR 4284A

Hello,
I want to use the labview VI to record the measured voltage and current values from LCR 4284A. These are shown as Vm and Im on the instrument screen. Is it possible to record these values using a VI?
I have looked through the drivers that are available through the "Instrument driver network" (Link) for 4284A but none of the VIs give any option to monitor Vm and Im. If you know how this can be done then I would really appreciate a reply.
Thanks
Mansoor

I haven't used the instrument but there are functions to enable/read voltage level and current level monitors. Are those different than what you are asking for? What does the manual say about Vm and Im and programatically getting them? If you can find the command in the manual, you can just open the VI Tree and do a text search for the command.

Movable cursor that is able to detect the peak automatically

Hi i am facing a troble with my labview program and i really need help! I was trying to link my peak detector threshold to my graph cursor in order to find my peak point. But when i move my cursor towards my graph starts getting "cut off". But when i open the peak detector example vi, their peak detector was able to locate all the graph peak without "cutting off" their graph. Why is that so? plz help me! thanx. Here is my vi.

The peak detector graphs the amplitudes vs locations in an xy graph. You only graph the amplitudes in a waveform graph. Whatever you are doing is completely different.
Graph the data AND the detected peaks in an xy graph, for example.
You might also want to throttle your code a little bit. At the moment, it uses 100% CPU doing the some old calculations and displays over and over. The loop only needs to spin if something changes.

I have a issue screen recording on my mac with quick time player. I have a 13' MacBook Air and i am able to screen record perfectly. But when I Plug in my head phones in to the port I am not able to record the audio.Only just the screen rec

I would like to know If I will be able to record(using quick time player) both audio and video on my mac with head phones connected

Hi Sansony,
Welcome to the Apple Support Communities!
I understand you would like to record audio from the headphones you connected to your computer. When recording audio with QuickTime Player, you can choose to use the built-in microphone, an external microphone you’ve connected, or a microphone from a connected Apple display. Please use the following article as a reference.
Mac Basics: QuickTime Player creates, plays, edits, and shares video and audio files
http://support.apple.com/kb/ht4024
Clicking the triangle icon gives you additional options, such as letting you choose whether to use the built-in microphone on your Mac, an external microphone you've connected to your Mac, a microphone from a connected Apple display, or the option to simply use no microphone at all. The triangle also allows you to adjust the finished quality of your screen recording, select whether or not your mouse clicks are shown during the recording (the pointer is highlighted when you click), and to select what location (on your Mac) to save your screen recording when finished.
Have a great day,
Joe

How to see the peak values in a chart?

I have the following situation: I am applying the FFt to an acceleration signal. In the FFT-peak graph I see different peak frequencies. However I would like to know how much are those peak values and either display them in the chart on top of the peaks or extract them in numerical indicators. Is any of these solutions possible in LabView?
I guess the question stands for any kind of graph or chart where you want to extract and see only certain or peak values. Any suggestions?
Thank you.
Radu

OK. Attached is a VI which allows you to move cursors 0 and 1 to select any section of a graph, and then click a button to get the maximum of that particular section. It also places the third cursor (red) at the location of the maximum it finds. It is all done using property nodes of the graphs.
This VI is based on an exercise of the LabVIEW Basics II course, which I took a long time ago, but the manual of which is still very useful.
Hope this helps.

I am not able to read the xslt table column value.

Hi,
I have the scenario like this.
I have two irpt pages first.irpt and second.irpt and saperate xslt tables for each page and common js file for two pages.
when I click on first.irpt page xslt table row that opens the second.irpt as a popup window then I click on the column in second.irpt xslt row after that column value should be inserted in to first.irpt xslt table column.
In above I have done everything except I am not able to update the first.irpt xslt table column as Even I am not able to read that value.
For your reference:
/* This function will be called when we select the row in first.irpt xslt table here SelectBatch_b.irpt means second.irpt
function getBatch(row)
var id=row;
var material=document.getElementById('Material_'+row).value;
var location=document.getElementById('StoreLoc_'+row).value;
var plant=1000;
var strUrl = "SelectBatch_b.irpt";
strUrl = "?plant="plant"&""location="location"&""material="material;
 window.open (strUrl,"mywindow");
/*This function will be called when we select the row in second.irpt (SelectBatch_b.irpt)
function getBatchID(row)
var Batch=document.getElementById('Batch_'+row).value; // reading second.irpt xslt table column value
document.getElementById('Batchc1').value=Batch; // reading first.irpt xslt table column value and inserting.
window.close(); // here I am getting error like object expected.
Please help me in this .

Hi Rajkumar,
Please find below the method to pass the variable back and forth in .irpt page.
First Page:
var Toaccessinchildpage = "value";
function getBatch(row)
var id=row;
var material=document.getElementById('Material_'+row).value;
var location=document.getElementById('StoreLoc_'+row).value;
var plant=1000;
var strUrl = "SelectBatch_b.irpt";
strUrl += "?plant="plant"&"+"location="location"&"+"material="+material;
window.open (strUrl,"mywindow");
function populate(strBatch)
 document.getElementById('Batchc1').value=strBatch;
Second Page:
function getBatchID(row)
var Batch=document.getElementById('Batch_'+row).value;
window.opener.populate(Batch);
window.close();
You have to call parent page function from child page.
No need to use common js.
If you want to access variable from parent page use
window.opener.<variable name>.
Example
window.opener.Toaccessinchildpage
You have to declare that variable as global variable in Parent page js file.
Refer First page code.

Selva

User is not able to find the receipt to correct it from Iprocurement.

User is not able to find the receipt for PO to correct it. User logged into iProcurement and queried for this PO but system says no data exists.
I checked there is a receipt for this PO and the same can be queried in Correction window through core APPS.
Could you please help why its not available in iProcurement for correction.
Thanks in Advance,
AVN

Are you logging into right organization (OU) to check the receipts?
Check your ship to location in PO and then based on that change your organization (through responsibility or change organization) then query yur receits, it should come.
BTW for receipts to be seen, the PO lines should not be in "CLOSED" status!

How can I display the correct enum ring value from a parameter file?

A user will make selections based on the menu ring (there are several of these) and then the values are saved for later use as a parameter (text) file. I have several menu rings which I write out to a parameter (text) file.
How can I take these text values back into the appropriate location in the menu ring. For example, if I have menuring_value at index 0, menuring_value at index 1, etc. how do I make sure that, when the par (text) file is loaded, the saved values are the ones displayed without erasing the displayed menu ring value and inputting the saved one (from the parameter file). I would like the text value to search the appropriate menu ring, make a match and then display that menu ring value when the parameter file is loaded.

If I understand your question, attached VI should have solved your doubt
In this example, Configuration File VIs are used to save & retrieve MenuRings' statuses.
As this VI is improvised, please further modify it to suit your needs.
Cheers!

The problem of return value from a method

Hi everyone:
I want return a value from following method. The basic idea is that I want use Num as a parameter to get a value from a field, therefore I can input this value into another database for the display purpose by using other classes. However I got error message when I compiled it.
"method does not return a value"
I know it is a problem, but how I can fix it? I need your help. Thanks in advance.
Dawei
Method:
public int Read(int Num) {
try{
String qr1 = "select Record form Buffer where Record="+Num+"";
ResultSet rs = statement.executeQuery(qr1);
while (!rs.next()){
          int result=rs.getInt(1);
return(result);
     catch (SQLException e){
               System.err.println("Error in inserting into database " + e);
                    System.exit(1);
return 1;

"select Record form Buffer ...Hopefully "form" is actually "from" in your code.
You have three points of exit from your routine, and only two return value statements.
1 -Return inside the while loop has a value.
2- Return inside the exception block (not sure that '1' would be a valid number)
3- The very end of the method, just before the last '}' does not have a return statement.
By the way, this question has nothing to do with JDBC, so another forum might be a better place to post it.

How to get the Open Order Qty value from Transaction Code RWBE?

Hello,
Recently I have a program that needs to extract the value of Open Order Qty value from RWBE.
My specific steps are as follows:
- I go to tcode RWBE
- I select the material and plant
- I tick the checbox for "Also select special stocks" and "Also select stock commitments"
- I execute the program double click one of the rows for the Unrestricted Use coulmn and view the Open Order Qty.
My question is how is this particlar variable attained? I tried Ekbe and the ELIKZ feild from EKPO and I still cant seem to get the right value.
Hope to hear from you soon.
Thank you and good day.

check with FM :
CALL FUNCTION 'MB_ADD_PURCHASE_ORDER_QUANTITY'
 EXPORTING
 x_matnr = t_matnr-matnr " TGA/4.6 Erw. Lot
 x_meins = t_matnr-basme " TGA/4.6 Erw. Lot
 x_matnr = prt_matnr-matnr " TGA/4.6 Erw. Lot
 x_meins = prt_matnr-basme " TGA/4.6 Erw. Lot
 x_elikz = space
 x_loekz = space
 TABLES
 xtab = xtab
 xwerks = r_werks.
above fm will get open order qty for given material in po

Get the attributes NAME and VALUE from an XML

I really love this forum :)
I load an XML an populate a Tree, from which I start to drag
items.
the xml looks like this:
<myTag attrName="attrValue"
otherAttrName="otherAttrValue"/>
var ds:DragSource = event.dragSource;
var var1:String =(event.dragInitiator as
Tree).value.@attrName;
-> the var1 variable has now: "attrValue"
my question is.. how can I get all the attributes' names? in
this example: attrName and otherAttrName (suppose I don't know the
structure of that xml node)
what about attributes values?
thank you!

The snippet below takes an xml node(nodeCur), loops over the
attributes list and builds an array that contains the attribute
name and value for each attribute. It comes from a sample app that
allows you to edit an xml file.
Sorry that the forum will remove the formatting
var aDPAttributes:Array = new Array();
var xlAttributes:XMLList = nodeCur.@*;
var attribute:Attribute;
for ( var i:int = 0; i < xlAttributes.length(); i++) {
aDPAttributes.push({name:xlAttributes [ i ]
.name(),value:xlAttributes [ i ] });
dgAttributes.dataProvider = aDPAttributes; //set the property
sheet dataProvider
