How to interface multiple NTC Thermistors to a 8-1 multiplexer and then to myRIO .
I need to measure the temperature of 8 lithium ion battery cells in series individually for my battery management system . So I need to see how can I interface the 8 thermistors with 8 to 1 multiplexer and output to myRIO analog input.
Hey Bakry77,
To expand on what Jeff said you can use an analog multiplexer like this one:
http://www.digikey.com/product-detail/en/HEF4051BP,652/568-1689-5-ND/763293
http://www.nxp.com/documents/data_sheet/HEF4051B.pdf
The 8 thermistors will need to be connected to Y0-Y7 and the myRIO analog input to Z. Then you can use 3 digital outputs from myRIO connected to S1-S3 to select the channel (Y) to pass through (Z).
Let us know if you have more questions about this. I'd love to see the code and your system when you get it working.
Thanks!

How do I move an object from one photo to another and then change the scene, i.e. winter to sum?
How do I move an object from one photo to another and then change the scene, i.e. winter to summer?
OK.
Open the picture with the new scene. This will be your canvas.
Open the picture with object A, select it with one of the selection tools, go to Edit>copy
Go back to the new scene/canvas, Go to Edit>paste
Repeat for object B
Use the move tool to position A & B, each on its own layer. Use the corner handles of the bounding box to resize, if necessary
You should have 3 layers: Background layer, and the 2 layers with A & B
Note: It's best if the resolution of the 3 picture files is the same value. -

Hey everyone in Apple world!
I figured out how to fix the flashing yellow screen problem that I've been having on my MBP! Yessssss!!!
I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
I followed the instructions on this page and here's what I did:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process. Since I did that, my MBP boots up just like normal. No flashing yellow screen anymore!!
(Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
Let me know if this works for you!

How can I remove a person's face from a photo and then replace the spot with a person's face from another photo?
In Editor, go to the expert tab.
Open picture B, the one you wish to select the "replacement" face from to add to another picture.
Use one of the selection tools, e.g. selection brush, lasso tool, to select the face. You will see an outline ("marching ants") once the selection is complete
Go to Edit menu>copy to copy the selection to the clipboard
Open picture A, then go to Edit>paste
Use the move tool to position the face from picture B to cover the face on A
In the layers palette you should see picture A as the background layer, and face B on a separate layer -

Bought Garageband for iPad1 and it worked like a dream. Then I upgraded my system to 4.3.5 and now Garageband doesn't work. How come? When I try to start it just flickers and then goes back to show the symbol for the app.
I understood what you were saying. You did type 4.3.5 in your post. Several other things to try.
Close all open apps like I described above. Just tap the home button first so that you will be able to access all of your apps. Close every single one and then restart again.
You can also delete the app and download it again. As long as you use the same Apple ID and password there is no charge to download it again. Tap and hold down on the GarageBand app icon until it wiggles. Then tap the X to delete it. Download it again.
Reset the iPad. Hold down on the sleep and home buttons at the same time until the Apple logo appears on the screen. It takes about 10-15 seconds. Ignore the red slider shut off bar. When the Apple logo appears you can let go of the buttons and the iPad will reboot.
The final thing to try is to download another app - any free app. Sometimes that seems to reset something on the iPad. You can always delete the free app if you don't want it. -

I find that I can sync fine with Entourage and I cal under Leopard. I can also subscribe to the Leopard I-calendar on another computer (running Tiger). However, the calendar will not go onto a web page as it used to; this is very frustrating for my colleagues! We need a fix here I think.

How come sometimes my iPod Touch gets stuck updating an app and then just deletes it?
How come sometimes my iPod Touch gets stuck updating an app and then just deletes it instead?
The update bar on the app gets stuck on empty and then the next time I sync the app gets deleted.
It is really annoying to lose all my data when updating an app, and it has happend more than once!
Any idea why it does this? I am scared to update my favorite apps for fear that they could be deleted.
-SamI never had an app being deleted. You can always udate the app on the computer and then sync.

How to bind xml generated by guide in Soap request message and then unbind it?
Hi
I have issue in "invoke web service" in adobe LC process ?
Actually , i have process, a long lived, which take input as xml . this xml(data) it get from guide data submission in browser by user?
Now , what i need to achieve here is that i have to invoke this long lived process in one of my other process via "invoke web service" option.And to do that, i need to bind the xml into Soap message and then it unbind to back same xml in the other process to use it?
so, my question here is how can i achieve that?Hello Iñaki
Thanks for your reply.
I had read the blog about the XMLAnonymizerBean. It looks very straightforward, and in theory should do just what I need.
I've added the anonymizer bean as the first module as the SOAP message is asynchronous, and I want to remove the namespaces from the request.
I want to exclude all namespaces so I haven't set any parameters.
The SOAP channel in Communication Channel monitor has a status of 'Channel Started but inactive'. I cannot see any messages in the Processing Details for this channel, even though I have sent test messages from Java code and from RWB (the message from RWB without the namespace does reach the receiver). This makes me wonder if I have not configured the interface to use the new SOAP channel correctly, although I can see it in the Receiver Determination configuration overview.
I can see the messages in SXMB_MONI but can't find which communication channel is being used by the sender.
I'm using PI 7.1.

How can I get JavaScript to detect if flash is installed and then load a different URL?
Hi, I've made two versions of the same site, one in flash and one in HTML, but I want the browser to detect what version of flash is installed, if any and then load the appropriate version of my site. I used to have it so that it displays a HTML message within the same window dependant on the whether the user has the right flash version or not and that used to work perfectly, so I think it must be to do with the changes I made to the if and else statements within the checkFlash() function.
Here's how I've made it so far:
<head>
<script language="javascript"> AC_FL_RunContent = 0; </script>
<script language="javascript"> DetectFlashVer = 0; </script>
<script src="scripts/AC_RunActiveContent.js" language="javascript"></script>
<script language="JavaScript" type="text/javascript">
var requiredMajorVersion = 9;
var requiredMinorVersion = 0;
var requiredRevision = 24;
var flashContent;
function checkFlash() {
var hasRightVersion = DetectFlashVer(requiredMajorVersion, requiredMinorVersion, requiredRevision);
if (hasRightVersion) {
window.open("http://www.yahoo.com");
else {
window.open("http://www.google.com");
</script>
</head>
<body onLoad="checkFlash()">
</body>
but the checkFlash() function isn't working for some reason, please help, much appreciated.terryfoster wrote:
Thanks Nancy O. Your post answered a few questions alas not the one I was after.
I have a div with overflow hidden.
Within this I wanted my content to slide in from the left to a positoin on the screen.
I found the effect I am after on a site - www.hullwebsites.com but I cannot afford to buy a control which is licenced on a per use basis.
So I am trying to come somewhere close with code of my own or a solution where I pay once for a single developer licence.

Sounds like you need a simple jQuery effect:

How can I save an app's data to my computer and then put it on a different device
I just made a new Apple ID on my iPod Touch 4thGen because my old one wouldn't let me buy anything grrrrr. So i made this new account to be able to buy things (even though i am not pleased that the old account had $10 left on it, grrrrr). I put $10 on this new account and went into Clash of Clans to buy some gems. Well since I had downloaded Clash of Clans with my old Apple ID it would not let me buy anything with the new account unless I redownloaded the app, but I do not want to do this because I would lose all my progress. So this brings me to my question, how can i get my app data back on my device after deleting it and still have the app functioning properly?
May I add that I called Apple Support on this and as soon as I asked my question, the person on the other line said the whole thank you for calling apple and then hung up! SCREW YOU APPLE CUSTOMER SUPPORT YOU ARE ABOUT AS USELESS AS WINDOWS!!!!!!!!Yo can't. apps are locked to the account thatpurchased them and in-app purchases can only be mad with the account that originally purchased the app.
You will have to recover use of the first account

How to open a "wav" file in Logic 7.2.1 and then remaster?
A fellow musician wants to see if I can improve audio tracks his band recorded in Cubase SX. He has a CD with the WAV files of each of 12 audio tracks. First question - Could someone tell me how to open his files and then import them into Logic Pro so that his tracks 1-12 correspond to my audio tracks 1-12 and be in sync?
Second question - assuming I can get his tracks going what are the key ways to boost volume or "master" his tracks so that the end result, a stereo mix, is loud vibrant and "radio ready"?
I'm familiar with the mastering plug ins on the output channels of Logic. I've used "Soft Maximizer" but it seems to be compression related. Are these "rooms", available on the output channels, the only way to increase volume and aliveness?
He's doing this because the studio he's at can't seem to make a mix that he's happy with. He says the mixes lack volume and vibrancy. Thanks in advance.Use the Audio Editor window to import the tracks. Then drag them one at a time onto Audio tracks in the Arrange window so they all align to Bar 1 1 1 1.
The fun will start if they were not recorded simultaneously as you will need to align them manually to be in sync. Good luck with that it takes time but is not impossible. Use the moveable start point in the Audio Editor to adjust the start of each wav file until they are aligned.
To improve the levels, probably the quickest way is to Normalize each track first in the Audio Editor window before you start mixing and EQ'ing them in Arrange.
