SVTK Convert back to G's peak after converting to IPS

In the Sound and Vibration Toolkit there is a VI that takes acceleration data in the frequency domain and integrates it to velocity (I am converting to IPS-peak). I would then like to apply a calibration slope and offset to the IPS values (which I can do) but then I need to convert these scaled IPS back to Gs-peak. Is there some sort of derivative function in the SVTK for data in the frequency domain? I thought there may be, seeing as there is an integration function.

Hi Greg,
Yea the SVFA Unit Conversion may be the way to go. Off hand I don't see/know of any specific VIs for this. Alternatively, will the Derivative x(t) do it? Not S&V, but you may be able to leverage it to do a raw derivative on the data. Just a thought.

I think this is what we're going to end up doing, tell me if it makes sense or there is a flaw in my logic. The accelerometer returns g's in the time domain. We will convert that to g's in the frequency domain and calibrate at some set frequency. From there, we can integrate our calibrated g's peak data in the frequency domain to IPS-peak in the frequency domain. We can also apply our calibration slope/offset from g's in the frequency domain to g's in the time domain.
The thing I am concerned about is my last sentence, can a calibration slope and offset in the frequency domain be used in the time domain? I would assume so because x g's is x g's, whether or not you're saying x g's at y hertz, or x g's at time t. Sorry, lots of variables there! Hopefully that makes sense, but please tell me if I'm incorrect in this assumption.

PSD to JPEG - Converts back after closing.....

Trying to convert photo from .psd to .jpeg. I "flatten the layers" and "save as" jpeg......but as soon as i close out of image and then reopen it converts back to .psd???? Can anyone help?

Okay, so you are using some version of Photoshop Elements?
In PE Organizer find your file that you just saved and right-click on it. Scroll all the way down to the bottom of window that pops up and select "show properties." This will tell you what format it is. Also, when you "save as" make sure that you are including it in Organizer, otherwise you will not see it and will only find your .psd file. Alternatively, you could search for wherever it is saved on your hard drive and double-click it to open it.

System is giving different number after converting to account document

Hi Team,
we are not maintain number ranges as year independent ..we are maintain number ranges in FBN1 year is "9999"
we have one issue, For example my fiscal year is April to march before year end closing we have some park documents
ex number .4455 (document number) after year closing which is next fiscal year we converted parked document as accounting document
but system is giving different number after converting to account document which is not 4455,
as per SAP standards and even we are not maintaining number ranges year independent SAP should be give the same number
please give me better solution if you knows any SAP notes belongs to above issue kindly let me know
thanks

Hi Suresh,
thanks a lot your inputs, I will test and come back

Trouble with flickering after converting AVCHD files to Apple Pro Res 22

Hi guys.
I have figured out that Apple Pro res 22 is the best format for my AVCHD files.
But I am having trouble with the files after converting them to this format.
Every 60 frames I have a blurred frame.
This results in a flickering effect when watching the clip.
The original MP4 clip (AVCHD) plays fine on the Mac but when I convert is it flickers.
I have captured a still shot of the frame here
http://www.willpower.net.au/DOWNLOADS/FrameError.jpeg
Here are the settings I am using for the conversion
http://www.willpower.net.au/DOWNLOADS/Error.JPG
Here is the converted file in Apple Pro Res 22 format with the flickering
http://www.willpower.net.au/DOWNLOADS/SANY0007.mov
I'd appreciate any help that you can offer.

Actually I think I might have found the answer.
After diggin deaper into the camera manual I have discovered that the setting I had it on "Full HD" actually is interlaced not progressive. Even though tha badging on the camera says Progressive"
So I think something got lost when converting the files to apple pro res.
I just shot a 10 sec clip on "Full HR" which is the progressive function and it converted nicely.
I'll come back to this post after shooting and making a little test movie today.
Thanks for your help.
PS. I wonder what codec it actually shoots in. Apparently it is not AVCHD but MPEG-4 AVC/H.264 compression (I thought that was AVCHD)

Convert Video files in iTunes but no Audio after converting

Hy, do somebody know what is the matter if i want convert Video files in iTunes (8.01) but after converting the files don't have any audio but i can see the movie perfect in iTunes and on ATV ????

Your likely using muxed video such as mpeg1/mpeg2, which is capable of being played back in QT (with the QT mpeg2 playback component in the case of mpeg2 source video) but not able to be converted.
I could well guess which software you should use to undertake your conversions but it would be better if you could provide details of our source video so that we can suggest an appropriate workflow based on that information.
You can use the Inspector window in QT to see this information.

Quicktime's trim tool doesn't stay after converting video

I had a bunch of mpg files that I only needed a portion of in Final Cut. Because that format doesn't work in FCP, I needed to convert them
To save time, I used the trim function on quicktime to just get the bits I needed. However, I noticed that after converting the MPGs to DV PAL, they reverted back to their original length. I tried a couple of other formats and the same thing happened. Can anyone help?

I just tried to use QuickTime to trim mp4 video clips, after trimming I can expoted video clips to iTune or
other folders. Somehow my quicktime could not play mpeg video directly, so I need to user other software (
Wondershare video conveter) to first convert mpeg video to mp4 format, then use QuickTime to trim mp4 video clips.
Hope this may help

My classic video ipod won't switch back to regular video mode after using it on an elliptical. The port still allows me to charge and works on the elliptical and treadmill but it will no longer change modes to allow me to watch my shows on the ipod screen

From the iPod's Main Menu choose Videos -> Settings and make sure TV Out is set to Off.
Otherwise, try a hard reset as well. To do this, press and hold both the Select (Center) and Menu buttons together long enough for the Apple logo to appear.

I have the same problem and
have followed the link uninstalling in the correct order,
then restarted as per instructions,
went to Apple to download itunes,
hit download now,
Visit the iTunes download page. Click Download Now to download the iTunes installer. When prompted, click Save (instead of Run).
did not get a save instead of run prompt
Right click on iTunesSetup or iTunes64Setup (the installer you downloaded in step 3).
If you have Windows Vista, Windows 7, and Windows 8: Choose "Run as administrator."
i can only click run as administrator from right clicking the shortcut on my desktop screen
If iTunes fails to install or repair, it might be necessary to remove components left from a previous installation of iTunes and then reinstall.
sick of doing this
at least 7 or 8 times i have re installed itunes to no avail
troubleshooting no better
please help. pulling my hair out at this stage

Stateful session beans are not persisted across restart of the EJB server instance(s) hosting them. You can't treat a Session bean as one would an entity bean.

Obviously I need to speak another language for you.... AGAIN my intentions were to answer the original post... Obviously more than one person has had this issue... I didn't create the post! If you take the time to read what I have said, I in fact wasn't the one asking the question, I was answering it! It's funny your on an Apple forum stating that information given by APPLE is incorrect.... Mind boggling! When answering a question on a forum, there are those that will disagree with the answers you have provided..SO WHAT! My life goal is not to answer to you or anyone else's satisfaction... Get over it.. You call it splitting hairs, I call it stating my opinion...I would have had to provide a service in order to provide a disservice, to which my opinion is not! If you don't agree with what I or APPLE has said, shrug and move on....

The person who sent you the gift can either try resending it to somebody who doesn't already have it, or they can try contacting iTunes support and see if they can get a refund or credit for their gift : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption

I'm trying to burn my audiobooks on CDs. Got through three books just fine, then my CD/DVD drive "disappeared." I rebooted and got it back, but iTunes says, even after I un- and re-installed it, that it doesn't have the registries to burn CDs.

I'm trying to burn my audiobooks on CDs. Got through three books just fine, then my CD/DVD drive "disappeared." I rebooted and got it back, but iTunes says, even after I un- and re-installed it, that it doesn't have the registries to burn CDs. How can I retrieve this capability? My audiobooks are from Audible.

I'd start with the following document, with one modification. At step 12 after typing GEARAspiWDM press the Enter/Return key once prior to clicking OK. (Pressing Return adds a carriage return in the field and is important.)
