FFT / BFF... Important?

• Create multiple vertical lines for waveform graph

  Hi all

  I use NI 9234 USB vibration of rotating machinery data acquisition. A simple VI was made for this.

  The next step is the analysis, signals were well displayed waveform, time, FFT, all important values... and so on.

  But I have a problem with multi vertical lines of the waveform graphs, it looks very simple, and I tried many ways but have yet to get it with a good solution.

  Vertical lines are used to display the frequency of breakdowns of machines (such as we post 1 X, 2 X, 3 X,... more harmonics).

  Does anyone have a solution for this problem?

  Thank you very much!!!

• FFT says after removal of offset CC

  I'm new to labview pls. I tried to remove the offset CC of a sinusoidal signal generated, but pointed out that the fft does not work well, he sees only the magnitude of the amplitude of the first. However, if I connect the signal directly without removal of dc, it works well. Can someone advise on what to do because it is important that I have remove the DC offset. And I don't want to presume that I am aware of the offset. My VI is attached.

  Use a slightly different technique to remove the offset. The DC - RMS.vi on average produces a waveform of offset values while you really want only a single scalar value. Use the Mean.vi (math > probability & statistics palette).

  

  There is no need to feed a waveform to the FFT.vi because it does not appear that the values of Y. If you want a cluster like waveform to feed to the chart, you can create your own from the sample rate and the number of samples or use the FFT (Mag Phase) VI spectrum in the range of Signal Processing.

  You also seem to have an aversion to the sons of the straight.  It is much easier to read and understand a block diagram if the wires have a minimum number of elbows and do not pass behind other objects.

• create a spectrum of the order from scratch (i.e. get a fft-based on the position of the same time deductions in the sample data)

  Hello people,

  THAT THE QUESTION PERTAINS TO:

  I play on 2 parameters of a system based on the sampling time: Rotary position and vibration (accelerometer g increments).  I want to take a fft based on the post to create a spectrum of the amplitude-phase speed order in / s.  To do this, perform the following:

  1 integrate (and scale) g vibration signal in the / s (SVT Integration.vi)

  2 signal sampled vibration resample the same time at an angle similarly charged signal (ma-resample unevenly sampled input (linear interpolation) .vi)

  THE QUESTION:

  Order in which operations should be carried out, integrate then resample or vice versa?  I didn't order would be important, but using the same set of data, the results are radically different.

  OR ORDER ANALYSIS 2.0 TOOLSET:

  I have the NO order Analysis Toolset 2.0, but I could not find a way to get the speed profile generation live to work with signals of position encoder DAQmx (via pxi-6602) quadrature.  In addition, it seems that I have to specify all the commands I'm interested to watch, which I don't really know at this point (I want to see all available commands) so I decided to do my own fft based on the post to get a spectrum of the order.

  Any help is greatly appreciated.

  Chris

  The order is to integrate the time domain of first - creating a speed channel.  You now have a new channel of data.  In general I would put this in the same table of waveform with waves of acceleration time.

  Then re - sample your acceleration and/or your speed signals, and then you can calculate the spectrum of the order.

• I imported my photos from an external hard drive in Lightroom, edited my photos but then...? !

  Adobe,

  I imported my photos from an external hard drive in Lightroom, edited my photos and when I decided to export the originals had not been updated and deleted photos were not deleted. How I set up so that once I have import photos, edit and export they are then placed in their original case reviewed and updated?

  I managed to export photos to another file, but they were exported with an Adobe.xmp file. What is it and is it necessary?

  Thanks for your help!

  OK then so when you export edited LR images to tell the Office I do not need to use xmp files unless I want then to re - edit still say in Photoshop or another app?

  You don't need the files xmp during the passage of LR to Photoshop. Right click on the image or in the develop module, click Photo > edit in... According to what you have set in the preferences of the image then opens like FFT, JPEG or PSD - 8 bit / 16 bit - and the new TIFF file for example automatically will return to sitting next to the original RAW LR library. If you are exporting a RAW file edited to the desktop to JPG/TIFF then changes will be permanently stamped in the EXIF of the created files.

  Basically import my Raw files on the drive from Carmera card, then in LR. Edit in LR, finishing and export again say in the office. Keep or throw originals that I please...

  Yes, but why would you throw your originals? You can later return to the original and the re - change all over again new experiences learned etc..

  Can I see the modified pictures made in Photoshop in LR later?

  Yes, see first paragraph above. If you already have a file in LR, take it in Photoshop as a JPG/TIFF/PSD, it will be automatically reduced in LR. If you modify a file outside the LR and that is not already in the LR library, say by locating the RAW file in Explorer and then open it directly in ACR/Photoshop, then LR will have no idea what you did except in LR, you choose to import the image later. Remember though, this is one of the examples where you will need to configure save metadata in xmp (at bridge) so that when you import the edited outside the file RAW LR, LR will read the xmp file changes and save it in its own database.

• Updated for Sierra and cannot import images

  I upgraded to Sierra and my camera, a Canon EOS 20 d is is properly recognized.

  Prior to the upgrade:

  When I plugged the camera would open automatically. I close and open Photoshop. PS I would like to select Import-> device and my camera would be identified. When I select the camer displayed thumbnails of photo.

  After the upgrade:

  When I connect the camera pictures only opens automaticall. If I open the pictures is not a camera attached.

  PS when I select Import-> my camera device is represented, but the icon is an external drive. When I select the icon nothing is displayed.

  Hello ChuckSto,

  Thank you for using communities Support from Apple. I know have a problem with your Mac and your camera is not what you expect. The good news is that the next steps will be useful for your problem of your camera is not recognized:

  If nothing happens when you connect your digital camera

  Try the following:

  • Make sure that the USB cable is properly connected to your camera and computer. If your computer has a USB port, try connecting the cable inside.

  • Check your camera to make sure he turned on and set to mode suitable for importing the photos. See the instructions that came with your camera.

  • Check the memory card of your camera for damage. See the documentation that came with your camera for more information on this page or other potential problems.

• Anyone know how to solve my problem? I can't import my photos from Iphone to computer. Sign says: Photos in the camera cannot be imported because the IPhone is locked with a password or read. My phone is unlocked. I've tried everything

  Anyone know how to solve my problem? I can't import my photos from Iphone to computer. Sign says: Photos in the camera cannot be imported because the IPhone is locked with a password or read. My phone is unlocked. I tried everything, every single idea. Without success! Any other idea?

  For example, you specify that the device does not display the lock screen, correct? Do you use Touch IDS? If so, try to put your finger on the device to see if it's what he wants.

• Change the name of the file of "Import.xls" selection in Applescript

  Hi, I'm a tiger, but I try to change the name of a file in a folder (which can be any name that is) a name known.  In the end, just trying to import a file known to filemaker and need the name to be a known name.  That's what I have so far, but I have simply not success.  This goes to the folder 2 window and selects the first file... no problem, but, I can't seem to change the name of 'import.xls '.  Only excel files will be present in this folder, so I'm not worried about it.

  The other thing I would do is if there is no file in this folder to jump above everything and do nothing.

  Thanks for your help!

  Tell application "Finder".

  activate

  the value target of Finder window 2 to folder "Orders_to_Enter" of folder "Documents" of the file 'MINIJOHN'from folder 'Users' of startup disk

  Select the first file of the window of Finder 2

  Try

  the value the name of the selection of "IMPORT.xls".

  end try

  end say

  
  

  say

  Hello

  No need to manipulate the selection. You can just write something like this:

  set d to (path to documents folder as string) & "Orders_to_Enter:" as alias
  tell application "Finder"
      --open item d -- optional
      tell (item d's file 1 whose name extension = "xls")
          try
              set name to "IMPORT.xls"
          end try
      end tell
  end tell
  

  Tested under OS X 10.6.8.

  Good luck

• iPhoto removes more after importation

  Obviously, Apple are trying to destroy iPhoto and you must use the abomination that is pictures (hideous interface and useless feature - seriously you're hiding a photo and it is still displayed in the photos - what's the point!).

  Anyway, iPhoto is still far superior, but after sierra * update * (is it really an upgrade, which makes it sound as if it was top!), in any case, after the passage at sierra when I plug my idevices in it transfers the pictures, but offers more delete them. So now I have to open iphoto, then unlock the idevice, then transfer the stuff in iphoto, then return to the idevice to remove photos ensuring that they transferred first, then quit iphoto.

  Apple, it's just works *, although probably no where near as simply as any other solution and that if you want to how Apple (trying to get rid of albums of places and/or people who popped in iOS 10!).

  (* Apple defines "works" means that the function may or may not work and may or must not cause a significant waste of time and/or loss of content.)

  Is it possible to transfer/delete functionality works correctly?

  So now I have to open iphoto, then unlock the idevice, then transfer the stuff in iphoto, then return to the idevice to remove photos ensuring that they transferred first, then quit iphoto.

  You can launch the Image Capture.app and import the photos in a folder in the Finder and then import this file into iPhoto.  If you use the transfer of images, you can always remove distributed after importation.

  But in fact, it is not recommended to remove the pictures from the camera before convince you yourself, that the imported photos have been transferred without transmission mistakes and make the first backup. I've seen quite a few posts here, where iPhoto crashed during importation or imported photos have been corrupt and if that happens, you will not be able to resume the transfer, if you let iPhoto delete photos immediately.

  The way you describe it is best practices, and how you should be important, even if the delete after import option was still available.

• Importing photos is no longer imports of Canon EOS 20 d

  Since the update to IOS 10/Sierra, the Photos is not automatically import photos from my camera. Previously, I would like to connect the camera to the USB port, open iPhotos and he would start the import process. I've rechecked through Capture of Image and importer self that my camera is recognized as a device. I have started and restarted several times; and double checked that my camera (Canon EOS 20 d) is compatible with the Sierra. My camera always does not appear as a device in Photos. Help, please!

• Import pictures and videos of 3rd generation iPad

  I have 3rd generation iPad IOS 9.3.5 (13G 36) and an iMac 2009 end MacOSX, (15-1004) 10.11.6.

  I always got imported all the photographs etc. taken on the iPad in 9.6.1 iPhoto (which I prefer) and Photos 1.5 (I appreciate that iPhoto is on its way, but I still don't like the Photos).

  However, I just tried to import four videos mov, which all or exposure perfectly on the iPad, and three videos will import the Photos but not the fourth and iPhoto import one of them even by selecting one at a time.

  Try to quit smoking pictures Gets the error message "do you want to continue to import?  Photos at present is to import files.  If you leave the import task is cancelled", but no progress is made on the importation and eventually it turns into a note saying that the file can not be imported.

  iPhoto, for all the videos of four whose three imported Photos, reports "error during downloading image.  iPhoto cannot import your photos because there was a problem of downloading an image"for each of the four video clips.

  How can I get all four videos in iPhoto or get him annoying that even of the pictures can not read on the iPad and imac where I can manipulate with other software?

  Unfortunately, the final video, about a five-minute long, is the largest, and I look forward to retrieve it from the iPad.

  Thanks in advance.

  Hi iBozz,

  I see that you have a question for the importation of four videos in iPhoto. It gives you an error that you cannot import your photos because there was a problem of downloading an image for each of the four video clips. Certainly, I know how it is important to ensure that you can get your downloaded videos on your computer. Let's see how I can help with that.

  I suggest to try this in a new user account to see if you get the same result when importing. If he succeeds in the test user account, this means that there might be a problem with the main user. Using tests in a new user account, please see:
  How to test a question in another account on your Mac.

  Let us know the results of this test. We'll help you get through this.

• iPhoto will not import pictures from iPhone 5 c after updating iOS 10

  Hi all

  After installing iOS on my 5 c 10, iPhoto will not import the photos. It is said that it can not because my iPhone is locked with a password. He does this even when the phone is open, and even though I have my access code is turned off. I use 10.6.8 on a Mac Pro Tour 2006.

  Everyone knows about this problem? Can anyone help? Thank you!

  Hi Mark,

  I guess it's a problem of compatibility between the leopard to snow & iOS 10 but, as a Test:

  Hold down the option (or alt) key and launch iPhoto. In the menu that appears, select 'Create Library'

  Import pictures into this empty library. The problem is repeated here?
