Displacement RMS value from acceleration

I am trying to get displacement RMS value from a signal obtained from an accelerometer. This accelerometer is connected to a shaker that vibrates at 159,2 HZ with an acceleration RMS value of 3,16 m/s2. At that frequency it's supposed to obtain the same RMS value for velocity (3,16 mm/s) anf for displacement (3,16 um).
I have used the SVT RMS level.vi using the signal obtained from accelerometer as input. I obtain the correct aceleration RMS value. Then I double integrate that signal using SVT Intgration.vi and apply SVT RMS level.vi, but the value I obtain doesn't mach with the expected one(3,16 um).
Should I eliminate DC componet of the signal before integrating it? Or before using SVT RMS level?

Your expected values are valid only for a pure sine. Every little offset from the DAQ of amplifier will result in different values.
So you should eliminate the DC in your first measured signal. Your integration time should be a multiple of 1/159,2 s
PS: use 159,155 Hz ;-)
PPS: If you want to do calibration take a look at SAM (Sinus approximation method)

How can i create an indicator to read the RMS value of my FFT using FFT Spectrum (Mag-Phase).vi

Hai to all,
how can i create an indicator to read the RMS value of my FFT using FFT Spectrum (Mag-Phase).vi.
as u can see in my block diagram(attached), i can use statistic to read the RMS value for the data but i cant's use it on the FFT Spectrum (mag-Phase).vi .
Thank you for helping.

Calculating RMS value of data samples in RT

I am using CompactRIO 9014 in my control application. I am acquiring data from NI 9215 module. I want to calculate RMS value of data coming from this module for monitoring of the system. I want to include data samples within 1sec to calculate RMS value. I am sampling at 25KHz rate. I want to use RT for processing there a way to do this? I am using Labview 8.6.

Hi suni,
Yes, you can do the processing on the RT host - that's actually the recommended way of doing things. I suggest using a DMA FIFO to transfer the data from your FPGA to the RT host, however you don't want to make your FIFO 25k elements long. Instead, you can write/read the FIFO in chunks (recommended size is under 8196 elements). Then, as long as you're reading from the FIFO at a reasonable rate on the RT, you should be able to pull out the elements and perform the RMS calculations.
If you're new to FPGA, I highly recommend looking at the examples in Help > Find Examples > Hardware Input and Output > compact RIO. A lot of them demonstrate communication between the FPGA and RT hosts.
Hope this helps!

Simulate arbitrary signal getting rms value

Hello!
I´ve got a .lvm file (attached as testpwm.txt) that generates a preview in Simulate Arbitrary Signal but shows nothing in the waveform graph. I would like to calculate the rms value and the duty cycle of the signal, but it doesn´t work together with the Express VI. I have also tried to build the waveform with Read waveform from file, but it doesn´t work either.
any ideas?

Hi Dongre,
What do you mean by "but value varries from 0 to rms which is not required. "
If you are using EPS 2014, you should first identify the type of data acquisition cards you are using for your cRIO 9076 (SAR of Delta-Sigma), and then choose the examples with the corresponding type in name in the Power Quality folder. These are more ready-to-run than the examples in Basic Power Measurement which are for DAQmx, but which could also give you a straight forward view of how to measure RMS.
You need to check the data acquisition modules on your cRIO for acquisition precision. If they are different from what's used in the examples, you need to manually modify a bit. Refer to the link below for how to adjust precision when you change for another module.

Rms value measurement?

I tried to measure the rms value of a small ac signal ( 6v rms, 50 Hz)

the rms value output using Basic dc rms .vi was not a constant value. But
simply the magnitude of individual samples and the constant rms value
(6 V) was not obtained. How to solve it?

DC/RMS value of waveform question!

Hello,
This would probably a very common question, but I hav a DAQmx system sampling 1000 AI samples at 1000Hz. I would like to get the DC value of each and individual point of this waveform.
when i use the Basic DC/RMS.vi and write the data to a file using Write to Measurement File.vi, i do not observe 1000samples in 1 sec.
however, i observe only 1 sample/sec, because the loop frequency now becomes 1000samples/1000Hz = 1 sample/sec..
is there a way that I can write all the 1000samples in 1 sec to file? Any other vi or logic?
any help would be appreciated... thanks

That may be a much more complicated question.
1. You have a high frequency signal. Does this signal have a DC component or are you just interested in the total RMS value?
The signal does have a DC component in it, and that's what I am interested in...
Is the time varying part of the signal periodic?
Ideally, it should not be, but I am observing a periodic pattern in the output waveform,.
Do you know the period or frequency?
Yes, it is around 20Khz, (that's what is the input to the signal)
2. What kind of conditioning does your signal conditioner do?
This is a signal conditioner for AC lvdt, made by Analog Devices AD598. performs the calculation based on ratiometric type of signal conditioning, where, Vout = (Va-Ab)/(Va+Vb), Va and Vb are the voltages
out of secondary of LVDT, input freq to the LVDT is 10KHz at the pri, 3Vrms
Does it rectify and filter the signal? Does it do a true RMS covnversion or is it average responding but calibrated for RMS for sinusoidal signals? Does it do the kind of signal processing you want?
It does rectify internally, there is a precision full wave rectifier inside the signal conditioner, so, I am assuming there should not be any further signal processing required once the signal is outputted from the chip.
3. Are you trying to measure the signal coming out of the signal conditioner or are you trying to measure teh original signal and produce an output after software signal porcessing which is similar to what the signal conditioner produces?
I am trying to measure the signal out of the signal conditioner.

How to get the values from table SKB1 R/3 to SRM

Hi Gurus,
My requirement is to get all the values from the table SKB1 to SRM (i.e. in to an internal table) for doing some validation(G/L account XXXXXX requires an assignment to a CO objectXXXXXX.)
Like wise I have many tables for doing validation in SRM
Help me how to get this, suggest me any Function module with sample code.
OR
Any Standard FM which will give all the values of the fields in the table SKB1 when I pass the key fields G/L account & company code alone so that I can improve the performance.
Suggest me.
Regards

Hi,
You can use the FM 's META_READ_TABLE Or RFC_READ_TABLE
Which SRM / Backend system version are you using ?
Are you taking care of the Importing paramater - DELIMITER in this case.. ??*
See related links ->
Re: Retrieving data from R/3 into SRM

How to get the values from popup window to mainwindow

HI all,
   I want to get the details from popup window.
      i have three input fields and one search button in my main window. when i click search button it should display popup window.whenever i click on selected row of the popup window table ,values should be visible in my main window input fields.(normal tables)
   now i am able to display popup window with values.How to get the values from popup window now.
   I can anybody explain me clearly.
Thanks&Regards
kranthi

Hi Kranthi,
Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

How to get multiple values from the list

I've a list of an item which I queried it from the database. I also created a button that will takes a selected items from the list when it was clicked. I used javabean to get the data from database.
<%     // clicked on Select District Button
Vector vselectedDistrict = new Vector();
Vector vdistrictID = new Vector();
String tmpSelectDistrict = "";
tmpSelectDistrict = request.getParameter("bSelectDistrict");
if(tmpSelectDistrict != null)
     // get multiple values from the list
     String[] selectedDistrict = request.getParameterValues("usrTDistrict");
     vselectedDistrict.clear();
     vdistrictID.clear();
     if((selectedDistrict != null) && (selectedDistrict.length != 0))
                       for(int i=0;i<selectedDistrict.length;i++)
               vselectedDistrict.addElement(selectedDistrict);
          vdistrictID = dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
          for(int i=0;i<vdistrictID.size();i++)
               out.println("district = " + selectedDistrict[i]);                         out.println("district ID= " + vdistrictID.get(i).toString());
%>
// get vdistrict from the database here......
<select name="usrTDistrict" size="5" multiple>
<%     for(int i = 0; i< vdistrict.size(); i++)
%>
     <option value="<%=vdistrict.get(i).toString()%>"><%=vdistrict.get(i).toString()%></option>
<%
%>
</select>
<input type="submit" name="bSelectDistrict" value="Select District">
Lets say the item that i selected from the list is 'Xplace' and I clicked on the Select District button,
what I got is this error message:
org.apache.jasper.JasperException: Unable to convert string 'Xplace' to class java.util.Vector for attribute usrTDistrict: java.lang.IllegalArgumentException: Property Editor not registered with the PropertyEditorManager
So where is going wrong and what the message means?. Any help very much appreciated. Thanks

These are just guesses that might hopefully steer you in directions you haven't looked in yet.
I presume you used triangle brackets (< >) to avoid having the Jive Forum think it was the "italics" tag?
Are you certain this: dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
expects a Vector as its second parameter? And returns a Vector?
I don't believe you've shown how you use the javabean, or its code? Perhaps it should be rewritten to accept an array of strings instead of a Vector?

SSRS 2012: How to get a "Select All" that returns NULL instead of an actual list of all values from a multi-select parameter?

I have a multi-select parameter that can have a list of thousands of entries. In general, the user will pick a few entries from the list or "Select All". If they check "Select All", I would much prefer that I get a NULL or an empty string
instead of a list of all values. Is there any way to do that?
In experimenting with a work-around, I tried putting an "All" label with a null value in the list, but it is ignored (does not display in the drop-down). If I use an empty string for the value, my "All" entry does get displayed, but so
does "Select All", which is confusing. Is there a way to suppress "Select All"?
- Mark

I adapted the following from a workaround posted by JNeo on 4/16/2010 at 11:14 AM at
http://connect.microsoft.com/SQLServer/feedback/details/249227/multi-value-select-all-parameter-in-reporting-services
To get a null value instead of the full list of all values when "Select All" is chosen:
1) Add a multi-value parameter "MyParam" that lists the values to choose.
2) Add a DataSet "ParamCount" identical to the one used by "MyParam", except that it returns a single column named [Count] that is a COUNT(*) of the same data
3) Add a parameter "MyParamCount", set it to hidden and internal, then set the default value to 'Get values from a query', choosing "ParamCount" for the Dataset and the one [Count] column for the Value field.
4) Change the parameter for the main report DataSet so that instead of using [@MyParam], it uses this expression:
=IIF(Parameters!MyParam.Count =
Parameters!ParamCount.Value, Nothing, Join(Parameters!MyParam.Value, ","))

Re: [iPlanet-JATO] Re: Retrieving all Values from a Tiled View

Todd,
Let me try to explain you this time. I have a text field in a TiledViewBean.
When I display the page, the text field
html tag is created with the name="PageDetail.rDetail[0].tbFieldName" say
five times/rows with same name.
The html tags look like this.
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
When the form is submitted, I want to get the text field values using the
method getTbFieldName().getValues() which
returns an array object[]. This is in case where my TiledViewBean is not
bound and it is working fine.
Now in case when my TiledView is bound to a model, it creates the html tags
as follows.
<input type=text name="PageDetail.rDetail[0].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[1].tbFieldName" value=""
maxlength=9 size=13>
<input type=text name="PageDetail.rDetail[2].tbFieldName" value=""
maxlength=9 size=13>
Now when I say getTbFieldName().getValues() it returns only the first
element values in the object[] and the rest of the
values are null.
May be we need to create a utility method do get these values from
requestContext.

I wanted to know how the getValues() method works the reason being,

What are you trying to do? What behavior are you expecting but notseeing?

Without further clarification, I can say that the setValues() methodsNEVER
populates data on multiple rows of a (dataset) model, nor does it affect
multiple fields on the same row. Perhaps what you are seeing is theeffect
of default values. Model that derive from DefaulModel have the ability to
carry forward the values set on the first row to other rows in lieu ofdata
in those other rows. This behavior is for pure convenience and can be
turned off, and it is turned off for the SQL-based models.

Hi,
I wanted to know how the getValues() method works the reason being,
when the tiled view is NOT bound to a model, it populates all the
fields with the same name as some thing like
PageDetail.rDetail[0].tbFieldValue
PageDetail.rDetail[0].tbFieldValue
in which case, the getValues() method works fine.
But in case where the tiled view is bound to a model, it populates
with different field names such as,
PageDetail.rDetail[0].tbFieldValue
PageDetail.rDetail[1].tbFieldValue
in this case, the getValues() doesn't work. Any soultion to this?
We are using Moko 1.1.1.

Help with getting values from request. Very Strange!!

Hello,
My very strange problem is the following.
I have created three dynamic list boxes. When the user select
the first list box, the second becomes populated with stuff
from a database. The third becomes populated when the second
is selected. Now, I have used hidden values in order for
me to get the selected value from the first listbox. The
following code is my first listbox:
<SELECT NAME="resources" onChange="document.hiddenform.hiddenObject.value = this.option [this.selectedIndex].value; document.hiddenform.submit();">
<OPTION VALUE =""> Resource</OPTION>
<OPTION VALUE ="soil"> Soil </OPTION>
<OPTION VALUE ="water"> Water </OPTION>
<OPTION VALUE ="air"> Air </OPTION>
<OPTION VALUE ="plants"> Plants </OPTION>
<OPTION VALUE ="animals"> Animals </OPTION>
</SELECT>
I use the getRequest method to get the value of hiddenObject.
At this time I am able to get the value of hiddenObject to populate
the second list box.
But, when the user selects an item from the second list box
and the second form is also submitted,
I lose the value of hiddenObject. Why is this??
The code to populate my second listbox is the following:
<SELECT NAME ="res_categories" onChange="document.hiddenform2.hiddenObject2.value = this.options[this.selectedIndex].value; document.hiddenform2.submit(); ">
<OPTION VALUE ="" SELECTED> Category</OPTION>
Here I access a result set to populate the list box.
Please help!!

Form parameters are request-scoped, hence the request.getParameter("hiddenObject"); call after the submission of the second form returns a null value because the hiddenObject parameter does not exist within the second request.
A solution would be to add a hiddenObject field to your second form and alter the onChange event for res_categories to read
document.hiddenform2.hiddenObject.value=document.1stvisibleformname.resources.option[document.1stvisibleformname.resources.selectedIndex].value;
document.hiddenform2.hiddenObject2.value = this.options[this.selectedIndex].value;
document.hiddenform2.submit();You will then come across a similar problem with your third drop-down if indeed you need to resubmit the form...
A far better approach would be to create a session scoped bean, and a servlet to handle these requests. Then when the servlet is called, it would set the value of the bean property, thus making it available for this request, and all subsequent requests within the current session. This approach would eliminate the need for the clunky javascript, making your application far more stable.

Retrieving ALL values from a single restricted user property

How can I retrieve ALL values of a single restricted user property from within
a .jpf file?
I want to display a dropdown list within a form in a JSP which should contain
all the locations listed in the property 'locations'. I ever get just the default
value when I access the property via
ProfileWrapper pw = userprofile.getProfileForUser(user);
Object prop = pw.getProperty("ClockSetup", "Locations");

Well, the code you've got will retrieve the single value of the property
for the current user. You're getting the default value because the
current user doesn't have Locations property set, so the ProfileWrapper
returns the default value from the property set.
I assume you want to get the list of available values that you entered
into the .usr file in Workshop. If so, I've attached a
SetColorController.jpf, index.jsp, and GeneralInfo.usr (put in
META-INF/data/userprofiles) I wrote for an example that does just this.
It uses the PropertySetManagerControl to retrieve the restricted values
for a property, and the jsp uses data-binding to create a list from that
pageflow method.
For a just-jsps solution, you can also use the
<ps:getRestrictedPropertyValues/> tag. I've attached a setcolor-tags.jsp
that does the same thing.
