Holding readings for certain period of time
LabVIEW beginner here. I'm logging particle count data generated every second from two identical instruments, one upstream of a substrate and the other downstream; they are labelled alpha and beta respectively in the attached VI. The counts plus penetration (beta/alpha) are written to measurement file once a second accordingly. This works fine so far but I need to correct for the aerosol transit time (=10 seconds) between the two instruments, so that the alpha reading at t=0 is paired with the beta reading at t=10s. How do I hold/delay the alpha reading for this time?

Ok attached a slight upgrade with a 10 element circular buffer. This presumes that your meas. data is being taken once a sec, and that is fine. There is a case statement that tells you when you have valid data after 10 iterations. There are other ways of doing this. So depends on what you are doing. I have also implemented the recommendation on the error clusters AND got rid of some of the Cohersion. I have upgraded my 8.2 version to 8.2.1, so I saved as version 8. Hopefully it still opens and works.

Blocking message notification for certain period of time
Hi,
We have a situation that requires that we do not process any messages even though they are messages sitting in the queue during certain period. Is there any programming API (I guess JMX based) where in weblogic JMS server can be notified to not to send messages until the block is lifted.
We are using weblogic 8.1 JMS implementation.
Thanks
SushilI have not done this blocking programmatically.
But blocking is configurable on the console at JMS Connection Factories -> Flow Control tab -> Send timeout. This blocking policy is configurable on the console at JMS Server -> Thresholds & Quotas tab -> Blocking Send Policy. Default value is 10ms. Change it to required time limit. -
How to keep that valve open for certain period of time and shut off automatically
Hi everyone,
The objective of the VI is to measure pH and then open acid or base valve based on pH valve. Below is my UNFINISHED VI
My question is: if, for example, the pH is 10, then, the program will open acidic valve for 5 seconds and then shut off automatically. After that, wait for 5 second. this process will go on and on as I use while loop, but I just dont know how to control the valve on for 5sec and off and then wait for 5sec.
Anyone can help me out? Thank you very much
In the picture, please enter those values before running
P.S The VI is based on previously posted vi by someone who made it 1 yrs ago.

Capture.JPG 79 KB1. The reason the valves close immediately is that the Elapsed Time VI does not cause any wait, it only measures the time. So the valves closed within a small fraction of a second of the time they opened.
2. I modified your VI to wait until the Elapsed Time has ended. See the "wait" state. I probably modified some of your other functionality in the process, but this shows one way you could do the timing.
3. You do not need any Value property nodes. They should never be used if the value can be wired directly.
4. You do not need any sequence structures. Dataflow will determine the order of things occurring.
5. If you use an enum for the state machine (and it is a good way to name and select states), you should make it a type def. Then when you need to change it as I did to add several states, you only need to change the Type Def in one place and the changes propagate through to every place you used the control or constants derived from it.
6. I added a Halt state which will close both valves before stopping the program. When you are controlling a real world process, it is important to consider the start up and shutdown requirements. For example the digital outputs of the USB-6008 default to inputs when the device is first powered up. And, the inputs are pulled high by a 4700 ohm resistor (at least I think I recall that value). Will this open your valves before the program starts running and sets the I/O lines to outputs and forces them low?
The USB-6008 has rather limited drive on the digital lines. You will probably need a buffer between it and the valve coils.
PID and PWM are more complicated than I want to get into here. First, are your valves proportional or on/off? Second, (assuming that they are on/off) how fast can you open and close them without destroying them in the first week? What is their expected lifetime in terms of the number of operations? How fast do you need to be able to change them to keep your pH where you want it? Are these values compatible?

Information on the reports that have run over a certain period of time
Hi everybody,
do you know any report (programme, table or other object) that provides with the information on what reports have been called by the users over a certain period of time in the past? I am especially interested in the reports in the customer name space (z-reports). Once there was a programme called RBE (Reverse Business Engineer) that could give this information, but it doesn't function in ECC 5.0 & ECC 6.0 anymore and no longer supported by SAP.
I would be grateful for any information. Thank you! NatTransaction ST03N will give you all the information you seek and then some!

Im on wifi but sometimes when i try and send imessages it wont let me for a period of time why?
If not thsi:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem. A trick that works frequently with iPhones:
Settings > AirPlane Mode ON, Do Not Disturb ON
Power down and wait 5-10 minutes
Power up
Settings > AirPlane Mode OFF, Do Not Disturb OFF
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.
Apple Retail Store - Genius Bar
Then
Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

I downloaded the latest operating system for my iPhone 5. It worked fine for about two minutes then the phone requested a password number to continue. Each time I inserted numbers, which were incorrect, the phone would lock up for a certain period of time. Now, it says “iPhone is Disabled”. It said to “Connect to iTunes” which I did, but iTunes does not recognize my phone. If I scroll the face to the right, it goes to the phone number face and says, "No Service". Can I do something to make the phone work?

No of RFC connections for a period of time
Dear all,
Is there any possibility to find the number of RFC connections hit to a server over a certain period of time?
I could not find any more details using AL08 since it gives the cumulative users rather than specific user type.
Regards,
Kumar
Edited by: Anees Qureshy on Jun 16, 2010 1:43 PMYa i have checked under that location.
But It will give the total no of calls that have been made.So if we assume 20 calls made,then im sure it does not imply that 20 connections have been made.
We have enabled a max of 2000 connections at any time.
But the number it is showing is in lakhs..I guess that is no of cumulative rfc calls made.
I still wait for a suitable reply. -

TS3899 How to fix Sent emails getting stuck in Outbox for a period of time before being sent?
How do you fix Sent emails getting s tuck in Outbox for a period of time before they actually send?
The error message says that my "sender address is rejected by the server", but it eventually does send.Have you tried a Reset [Hold the Home and Sleep/Wake buttons down together for 10 seconds or so (until the Apple logo appears) and then release. When the screen goes blank then power ON again in the normal way.] It is 'appsolutely' safe!

Restric materails from sales for certain period
Dear Gurus,
There are some materials that should be in quality inspection for specific period and after that period it should automatically release for unrestriced use stock. Basically we want to restric some material from sales for certain period and after that period it should be automatically avoid that restriction.
Please provide me a possible solution for this.
Thanks,
Regards,
Chameendriusually a human changes a status with a material movement, e.g. thru usage decision if Quality module is used.
there is nothing in customizing or master data where you can say the material becomes saleable after 3 day lying in the shelfs.
the GR processing time can be extended to 3 days, so ATP can know that the material is not immediatly available after goods receipt.
But this does not change a stock status from blocked to unrestricted (or quality to unrestricted).
If you want this, then you have to write a report that checks how long the batch is already in Q-status and then calls a BAPI for posting a goods movement to change the status. and this report can then be scheduled to run in background once a day. -
How to block internet connection for a period of time?

Some songs I purchased last night are not playing all the way through. Several songs from the 4 albums I purchased play for a period of time then just skip to the next song. The songs that do this, do it everytime they are played at the exact same spot. The songs that are affected skip to the next on iTunes on my PC which is updated to the most current iTunes and my 160gb iPod classic. Everytime they are played at the exact same spot. However on my other device, iPhone 4s all songs play just fine. I have almost 7,000 songs on my iPod and this has never happened before and I have played it awhile since downloading those albums yesterday. This is only happening with the albums purchased yesterday. Can anyone help me figure out what is wrong?
I'm having the same issue with a few songs I just downloaded. It skips randomly in the middle of the song.

How can I set my phone to delete messages after a certain period of time? 6 months, 1 year??? It is taking up over 4GB on my phone. I don't want to delete everything just the oldest ones.
If you update to iOS 8, you can select that in Settings>Messages>Keep Message and then select your option. If you don't update to iOS 8, you'll need to do it manually.

For OS X v5 or 6: Whenever I have internet access my disk is running continuously for a period of time without any activity on my part. When I close internet access the disk activity stops. Who is fishing for data?
Thanks for your reply. I don't use itunes so that couldn't be it. Reading about Little Snitch and Hands Off, however, educated me about the data harvesting in many apps and that when buying from the AppStore one will more likely get Apps with benign data harvesting.
