Wavelet transform scale and time information

Hi there -
I am using the wavelet transform for a non-stationary signal. I am not having trouble getting the coefficients from the transfrom but is there I way I can find the scale/frequency and time information from just the wavelet VI. I see no way I can get at this information. Also, I am pretty certain Labview uses the DWT when computing the transform but does Labview have the option to do the CWT?
The reason is because I want to plot time vs. frequency vs. amplitude and I need all three to do it properly.
Thanks for your help,
Cameron

Hi, Cameron.
This screenshot shows one DWT and one CWT VI, and you'll notice that the CWT has an output called scale info which contains the time information and the scale (frequency) information. (In addition, LabVIEW has several other wavelet VIs.)
If this doesn't answer your question, please let me know. Have a nice afternoon!

How to read the date and time information of a file by labview

how to read the date and time information of a file by labview? for example, created time and modified time.
Solved!
Go to Solution.

if you need to know the last modification date of file:-
"Functions->File I/O->Advanced File Functions->File/Directory Info.vi"
This vi returns the value of file's last modification date. This is returned as U32 number. To see it in MM/DD/YY format you must create the indicator, right-click on it and select "Format & Precision" item from drop-down menu. Then select "Time and Date" format there.
Thanks as kudos only

How to know date and time information from Trace File defaultTrace.X.trc?

Hi, all.
i'm using EP 6.0 SP9 patch 1.
As you know, default trace is written in the <SID>\JC00\j2ee\cluster\server0\log\defaultTrace.X.trc.
By using the default trace formatter, it shows like the following sample messages.
#1.5#0011110E7B2000590000000100000A100003EC71562E6EBC#1104396451585#com.sap.jms.server.ServerClientAdapter##com.sap.jms.server.ServerClientAdapter#Guest#18####716257115a3f11d9b73b0011110e7b20#SAPEngine_Application_Thread[impl:3]_23##0#0#Error#1#/Applications/JMS#Plain###JMS internal error at ServerClientAdapter! JMS Service is not started!#
My questions are
1. how do we retrieve the date and time information from the above message? It seems that this message has date and time info because LogViewer shows the date and time based on the above message.
2. how do we change the above date format to easier one
like "YYYY:MM:DD:hh:mm:ss"? i know that it can be configured from the Visual Admin --> Services --> Log Configurator but i don't know the exact place for the trace file.
Thanks.

Hi Sejoon,
I use the standalone Logviewer to read the log files. Works great.
"If you have an SAP Web Application Server Java 6.20 or below you may also get a standalone_logviewer.zip file at the SAP Service Marketplace at service.sap.com/download → SAP NetWeaver → Release 04. In this case JDK version 1.3 or higher must be installed on the system. The java version must be same on the server and the client.
In the SAP Web AS Java 6.30 installation a folder named logviewer_standalone can be found under: <path Of J2EE installation>/<SysID>/JC<nr>/j2ee/admin/logviewer_standalone. Verify that the batch file logviewer.bat is installed in the directory logviewer-standalone.

App uses -moz-transform:scale and touch registration is out unless double tap to zoom in.

I'm having awful trouble with scaling. When I get the screen resolution of my tablet is says 1280x800. However if I scale my page to fit using -moz-transform:scale it overflows the page and I need to scale it down by 0.76 to make it fit. Strangely if I use portrait which reports as 800x1024 the page is then too small and I need to scale it up by 1.23 (note its -0.23 and +0.23 for landscape and portrait respectively).
If I avoid scaling by making the page the right size (adjusted by 0.76) then in landscape touch registration is correct with relation to the page. In portrait if I do the same then I can't press the buttons unless I double tap to zoom in.
I can't change the way this app works as it works perfectly well across all Windows and Linux platforms but I have these bizarre things happening on Android.
The main issue is touch not registering correctly. However, when its not working if I hold a button down I get a javascript message pop up offering 'Copy link' and 'Bookmark link' with the correct javascript reference but the function is not called.
Any hints on how to work this out very welcome.

Slightly closer. I've added <META name="viewport" content="width=device-width, height=device-width, initial-scale=1.0, maximum-scale=1.0"> to my top level container. This seems to stop firefox from doing an auto-zoom so my page is now properly displayed in both orientations. In landscape all works fine. In portrait however my navigation buttons at the bottom have no touch response unless I double tap to zoom in and then they work. Strangely, the buttons in the content area that are generated on the fly work correctly even after I zoom out again.
Any ideas anyone?

Automatically creating data filename out of date and time information

I read somewhere (in a book, here ?) about a programmer who never keyed in a data filename to save his data file. He just used the system date and time to create his filename. For example: now would be 20028141032.dat (2002, August 14, 10:32 am)
I am looking to do something similar. I do want to add a spot of text after the date and time and save it as *.xls.
This way when you have a long list of data files, if you sort by name, they are sequentially in order.
Thanks for any help.
Terry

Hi Terry,
You can use "Seconds to Date/Time" Funtion along with "File Dialog" Function to accomplish your task. You Unbundle the cluster from the "Seconds to Date/Time" with Year, Month, Day, Hour and Minute Information Convert and Append into One String. You Can add Pre or Post text to this String. Wire this to File Dialog Box and it will Pop up the Window With File Name in it as Default. Also the extemsion of the file name can be specified here. The User has Option to change this or accept this default name.
I have attached an Example Vi to Illustrate this(LV6.1) Take a Look. To Use this Just Wire the Path Information to your Saving Functional VI. Also the Vi Checks if File Exists or Dialog Box is Cancelled. And You may Build Functionality for the
se if you need them.
Good Luck.

Transform Scale and Translate Math

I am using images to create my tab backgrounds. The center image is one pixel in width. To stretch it the length of the text on the tab. The problem is I don't understand the math I need to figure out the x value (below its 1-8.5) that will place the image back in the correct position.
Can someone help me with the math I need to calculate its original X position?
Also, how do I find the current width of a Text object? I have seen examples that used text.currentWidth, but it does not appear to be available anymore.
var center = ImageView {
     image: Image { url: "file:images/tab_center.gif"}
     x: bind left.getBoundsX() + left.getBoundsWidth()
     transform: [Scale.scale(50, 1), Translate.translate(-18.5, 0)]

Fetch Vendor block/unblock date and time information in Transaction XK05

Hi ,
When user blocked to vendor using transaction XK05,This data stored in the table CDHDR (bloked Date and time).
My quostion is how will we fetch the bloked DATE and TIME from CDHDR table( i mean which condition i need to fetch).
This table have the blow key fileds .
1) OBJECTCLAS       Object class
2) OBJECTID             Object value
3) CHANGENR          Document change number
Could you please help us to resolve this.. << Please do not offer rewards >>
Thanks
Satya.
Edited by: Rob Burbank on Jun 24, 2010 10:44 AM

In Development, repeat the block process, then go find what you just put into table CDHDR with SE11 or 16...a little innovation and initiative often allows one to discover precisely what is needed, if you'll pardon an admonition from an old programmer )

Date and Time in Sender File Adapter Target Directory

Hi there,
is there a way of using Date and Time from XI to the Target Directory naming? To use variable substitution some fields of the message had to contain that date and time information, which is not our case.
For filename you can use "add time stamp" option, but and for target directory?
Thanks and regards,
Henrique.

Hi there, Moorthy
We've tried to write that shell script that you mentioned, but now we have a few doubts on how to make it create the proper directory.
In the file adapter, my target directory is "/%var1%/%var2%/", where %var1% and %var2% are variable substitutions, referencing data which comes from the payload. Now, I need the shell script to append "/<Year>/<Month>/" in the target directory. But where to archive the script? If it stays in the root directory, than how to make it create "/<Year>/<Month>/" folders inside a directory which is variable (/%var1%/%var2%/)?
Is there a way of passing %var1% and %var2% as parameters for the shell script?
Thanks a lot,
Henrique.

Date and time stamp with Sony HDR CX7

Hi,
I am trying to figure our how to find date and time stamps for individual clips.
My workflow is as follows: I use disk utility to make a disk image (.dmg) of the memory stick and import the clips from this disk image. Everything works fine, but I am not able to find any date and time information on the imported clips.
I am slowly building a large archive of these disk images and I am wondering whether I need to add some some date an time info manually. I know that this information is recorded on the memory stick as the camera can display them.

Printing Date and time format LR 1.3.1

I am trying to print photos with date and time information underneath. Choosing "Photo Info" then "Date" allows me access to everything I need, but in the wrong format. The time is showing up as military (24 hr) format and I cannot find where to change this anywhere in Lightroom. Thank you for helping me with this simple question.

The PRAM battery normally lasts substantially more than 18 months. If you have extended, Applecare, warranty, have Apple look at it. Otherwise, you can either try to change it yourself or have some service shop do it for you. Take a look [righ here|http://www.powerbookmedic.com/Take-Apart-Repair-Manuals-p-1-c-258.html] for more info.
Besides losing the date and time, other parameters such as the volume, brightness, etc., will also reset to default due to PRAM failure.

CF8, Mysql, Date and Time 1 hour behin

Hi Guys we have CF8, and we are using Mysql 5.0 the
connection with the database is perfect
but we have a very estrange problem we store date and time
information into the database
when we query the database we get the right information
however when the coldfusion script
show the result in the web the information is 1 day behind,
I've been looking around in the CF8 administration to see if I can
change some settings without any success.
Example:
eventID eventType eventVenue eventDetail eventStart
eventstartTime eventEnd eventendTime eventLevel eventActive eventTS

1 yes 2008-03-12 17:22:59
of interest are the time and date columns eventStart,
eventstartTime, eventEnd, eventendTime - please note the values
retrieving that information (without modification) via
coldfusion are 1 day behind for dates (actually 1 hour behind) and
1 hour and 1 minute forward for time

We reproduce the problem in Windows or Linux so we believe
it's a problem with the coldfusion
can you give us any advise ?
Regards
Ivan

I don't think the problem with with CF. In addition to the
server's timezone, which JVM are you using? You need to at least
1.4.2_11 to account for the recent change in daylight savings time.

Emailing Photos from iPhoto 09 causes date/time information to be lost

My entire family just updated from iLife 06 to iLife 09. We are all running OS 10.5.7 and have installed all of the auto updates for iLife. Since the upgrade, we've noticed that if we email eachother pictures (using Apple's Mail program), the date and time information seems to get lost (this was not a problem before the iLife upgrade). When I receive an email with a photo attached (it was attached using the email button in iPhoto), when I import that photo into my iPhoto, the date/time are of the current import, not of when the photo was taken. Is this a known problem? If not, is there any way to fix this? Thanks!

Welcome to the Apple Discussions. The copies of photos that iPhoto makes for emailing and other uses are stripped of the EXIF data when edited or mailed using the Email button.
To keep the EXIF data with the files you email you will need to not edit the file and drag the thumbnail from iPhoto into an open email window. Once the photo is in the email body you can resize it using the menu at the bottom right of the email window.
Send a feature request regarding this to Apple via http://www.apple.com/feedback/iphoto.html

Date and Time on Mac OS X and Windows XP running diffrently... (Boot Camp)

Why the time differently when i change OS? I was used network time server on my both OS, but the time still wrong after i changed operating system... How can i solve this problem?
Thx.
Kelvin

Hi Kelvin,
The answer to your question lies within the Boot Camp Beta - Installation & Setup Guide. Under the Troubleshooting section on the last page. I quote:
My computer doesn’t always show the correct date and time.
The Windows XP and Mac OS X operating systems handle your computer’s date and time information differently, so the date and time may be different when you switch operating systems.
For best results, use a network time server. Resync the date and time whenever you switch operating systems.
To resync your date and time:
In Mac OS X, reset the option to “Set date & time automatically” in the Date & Time pane of System Preferences.
In Windows, click the Update Now button in the “Date and Time Properties” control panel.
Alternatively, you can manually set the correct date and time when you switch operating systems.

How to prevent calendar from deleting dates and times from event names?

Calendar automatically discards date and time information from titles of new events. For example, creating a new event with the text "Staff Meeting 9 a.m. board room" leaves only "Staff Meeting". Calendar discards the "9 a.m. board room" information without asking. This feature is not helpful to me. How do I disable it?

All of a sudden the transform tool and free transform tool are grayed out and will not allow me to scale, rotate, or do anything to an image I just scaled?

I've been using Photoshop for years, but tonight I ran into an issue that I don't understand. I was working with a file that I had been working with for months. I added a new image and resized it to fit as I needed just as I always have (select layer with image > EDIT > TRANSFORM > SCALE.) All was working fine. I added a second image to the file I was working on (I added it by dragging it into the file from another window just as I had added the first image.) However, this time when I tried to select EDIT > TRANSFORM > SCALE this option was not available to me. Only the FREE TRANSFORM PATH or TRANSFORM PATH options were available. When I selected the SCALE in the TRANSFORM PATH menu (just to see what would happen) it started to scale a completely unrelated layer that DID have a path to it. However, the layer of my image was still selected and NOT the layer with the path. This image layer has no path even on it or around it in any way. I tried to select the folder layer and the same thing happened. It selected this one path and tried to scale it. I selected the layer I just previously scaled and tried to scale it again and it will only allow me to select the transform path option. I selected it to see again what would happen and once again it selected this completely unrelated path on a completely different layer. WHAT????? This makes absolutely no sense! I have tried restarting both my computer and PS and it won't stop happening! I really need to get this file finished and uploaded to my developer ASAP so I really hope that someone has some insight as to why this is happening.

hedger,
How do you expect anyone to help when we don't know a darned thing about the file, abut your setup, exact version of Photoshop and your OS, machine specs, etc.?
BOILERPLATE TEXT:
Note that this is boilerplate text.
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),
exact versions of your OS, of Photoshop (not just "CS6", but something like CS6v.13.0.6) and of Bridge,
your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,
what error message(s) you receive,
if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
etc.,
someone may be able to help you (not necessarily this poster, who is not a Windows user).
a screen shot of your settings or of the image could be very helpful too.
