I ask for a suggestion to experts

I have a laser which performs measures at an high rate (order of magnitude 1 Khz).
I want to read and collect data at a lower rate from time to time.
So I must leave the laser doing its job, but I need to pick up just some of its data (actually the last data, when I am going to read inside it) loosing all the remaining data (and I really want to loose them). I hope I was able to properly explain myself.
In an ideal vi I MUST have an initialization part of the instrument at the beginning (just to be read once) and a closure part at the end (just to be read once) and a reading part of the laser in the middle to be read several times while the vi is running.
My question is the following. Have I to adopt the master-slave architecture with notifiers, or you can suggest me something else?
Thank you in advance.

My two cents worth. I agree with producer-consumer. It is built for that purpose. However, I would put the initialization code before the producer-consumer even starts, then put the shutdown code afterwards. Since both will only be called once, there is no need to complicate the consumer loop with a state machine. It would also make the code more readable. The Error In and Error Out wires can direct the execution flow to make this happen.

HT2534 When I try to set up an Apple ID, it's asking for a credit card, and there is no "None" option, like this page suggests. How can I bypass this? This iPad is for a younger child who has no credit card, and will not need to make any purchases.

1. Sign out of current Apple ID if you are sign-in to one (important)
2. Go to App Store and select a free app
3. Tap INSTALL APP
4. Create New Apple ID

Asking for Suggestions

I am here to ask for suggestions as to approach with Verizon Wireless as to an error they made that they want me to pay for.
You see, I send my payment on the 1st business day of the month, every month, even though the bill is not due until the 17th of the month. Twice now, Verizon Wireless has not credited my payment to my account - even though the check clears my bank (with a Verizon Wireless endorsement) within 5 - 6 calendar days from check date. I do not realize that the payment, which clears, is not properly credited to my Verizon Wireless account until the next bill is accessed and a $5 late fee is assessed.
In July, I paid my bill on July 2, and the payment cleared the bank on July 7. The endorsement was, in fact, Verizon Wireless. When I received my bill at the end of July, it did not show payment and included a late fee. I called immediately and was assured that the error would be fixed. I paid the current amount (minus the $5 late fee) and went on my merry way. Now, because in February of this year this happened, and all went well, I assumed that it would go well this time. BIG MISTAKE.
Fast forward to the end of August. STILL a past due (for the payment made July 2) PLUS that $5 late fee from the original "non-payment" PLUS an additional $5 late fee for the continued "non-payment." Coming uncorked, I call Verizon Wireless again. Basically was treated....poorly (that is being kind as to not be offensive). And, when I explained what happened, was transferred to an immediate payment person to "take care of paying [my] past due account."
It took seven days, but I finally got it through to Verizon that the bill had been paid. And the account was credited the payment.
But
Now the late fees are showing past due. In my perspective, I do not owe one penny in late fees because the darn bill was paid ahead of due date. And I won't pay one darn penny more than was used.
So, any suggestions from any of you who may have had a similar situation where you may have gotten late fees reversed? I am at a loss.
Oh, yes. The plan is being switched to that other wireless service provider because I am done with this.....
Any suggestions would be most appreciated.

thanks for responding
before traveling to the Bahamas I contacted VerizonWireless and was told to make the changes which I did what wad not relayed was the fact that Verizon did not have service there and every minute would be roaming. My thought was that at best the cost would not exceed $40.00 for the 5 data which I was okay with. The most dissapointing fact was that noone could contact me and U use the phone for business also.
This was the worst customer service that I have has since opening the account.
I would like to see some concessions seeing how I acted totally on what was recommended by Verizon.
Best Regards,
Joseph

Copy the iTunes folder from the disk to the Mac, and the iPhone backup to the right place on the Mac (Google for "iphone backup location"). Then when you restore you can reload the last backup.

I have followed the suggested methods of restoring my iphone by placing it into recovory mode, however itunes keeps asking for a response from my iphone except it is disabled

There's a whole lot to read in your post, and frankly I have not read it all.
Having said that, this troubleshooting guide should help:

OK. Open your PDF with Preview and at the top of the window (near the file's title) you will see Locked in grey.
Click on it and in the menu that appears click Unlock.
It looks like this in OS 10.7.3 :
For information you can view the permissions of a PDF file in Preview by choosing in the menu bar Tools > Inspector, and then click Encryption (the lock).
Hope this will help.

I can't answer why you are not able to connect to WiFi but I can tell you to try the basic things, turn WiFi off and on again, restart your iPad, reset network settings, reboot your router, forget your WiFi network and try again .....
The issue with the email is probably a password issue. Make sure that your password is entered in the incoming mail server setting and in the outgoing mail server setting as well. The outgoing server setting can be accessed by tapping on the SMTP under the Outgoing Mail Server Setting and then tapping the smtp.comcast.net in the next window under the Primary Server Setting.
The outgoing mail server setting will be in the first window when you tap on the Comcast account in the Mail settings.
Look here for a few different web sites for help with the WiFi.

It was mentioned that LinkedIn is free to download over iPhone but when I'm trying that it's reflecting GET and asking for payment verification. Please suggest.

It was mentioned that LinkedIn is free to download over iPhone but when I'm trying that it's reflecting + GET and asking for payment verification. Please suggest.
Please find the attached screenshot.

If it's the first time that you've tried to download anything from the store with the account then depending upon how you created the account then you may have to enter payment details before you will be able to download anything (including free items).
'Get' means that it's a free download, though that app does offer in-app purchases. If you are being asked to confirm/enter your card details then have you tried doing so ? As it's a free-to-download app the card won't be charged, though you may receive a temporary store holding charge.

I tried to restore from iTunes when connected to PC, however, it says it cannot do this because Find My Phone has been activated on the ipad. To deactiviate I need to turn it off on the ipad which required my iCloud password (seems I am in a catch 22).
Any suggestions on how to proceed?
Thanks.

Hopefully this will me get you back up.

My PC repeatedly asks for authorization when opening I-tunes library (wont let me play tunes), have tried ALL the suggestions to remedy authorization but to no avail. Anyone got any other suggestions I could try please? I would have thought I-tunes itself should come up with a precise answer to this sort of problem after all this time??

From the menu bar, select
 ▹ System Preferences... ▹ Network
Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.
Assuming that you've ruled out those possibilities, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.
