Can I use 7344 card to control other dynamic system

Excuse me
I want to control a piezoelectric stripe actuator, I just want to input a step function to the actuator and use the 7344 PID controller to control the actuator.
step input | 7344 | | | step response
--->o--->| PID |--->|actuator|--------->
^ |controller | ---------- |
| ------------ |
|___________________________________|
feedback
Dose 7344 controller satisfy my request?
Thank you

In fact the control algorithm on the 7344 can be used for a variety of control tasks. I have dealt with customers who use the board for controlling force, pressure, piezo stack actuators and piezo ultrasonic motors. As long as your drive provides an analog control input and an appropriate feedback signal (quadrature encoder or analog output) I don't see a reason why the 7344 shouldn't be able to control a piezo stripe actuator.
I don't know much about the characteristics of a piezo stripe actuator but maybe you will have to consider setting the parameters for a static friction deadzone in the 7344 configuration in addition to the normal PID parameters. You need to set these parameters whenever there is a deadzone around the zero voltage output. Refer to this link for further information about deadzone compensation.

Are iPad Air and iPad Mini Retina both "SIM unlocked" in US? Can I use SIM cards sold in other countries?

I'm planning to buy iPad Air and iPad Mini Retina during my trip to US.
Are they both "SIM unlocked"?
Can I use SIM cards sold in other countries?
Do I need any treatment or/and application when purchase?

If you are not concerned about LTE bands (which will be more diverse and hit-or-miss) the only ones that will matter are these...
3G: UMTS/HSPA/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
2G: GSM/EDGE (850, 900, 1800, 1900 MHz)
This covers almost all the 2G and 3G standards. You will most likely be ok on 3G and in edge cases, at an absolute minimum you will have EDGE speeds since both US and EU frequencies are covered - blech :-)

Can I use Java Card Development Kit 2.2.1 on Windows XP?

Can I use Java Card Development Kit 2.2.1 on Windows XP?
If no, which kit supports XP?

It is not as strait forward as per say.
I would like to share some tips that I have learnt duirng my recent experience with Java Card Development Kit 2.1.2 ( It presumed that JAVA SDK and JCDK is properly installed:
Additonal installation
- you need to download Java Communicatons API version 2.o for Windows at http://java.sun.com/products/javacomm/downloads/index.html
- unzip the downloaded file javacom20-win20.zip
- copy comm.jar and javax.com.properties to %JAVA_HOME%\lib
- copy win32com.dll to %JAVA_HOME%\bin
Configuration of Environment
- Activate System under Control Panel
- Click Environment Variable button under Advance Tab.
- Check that JAVA_HOME and JC21_HOME are there under User Variables for user123
- Create a new enviroment by clicking New button under User Variables and Enter "CLASSPATH" for Variable Name and ".;c:\j2sdk1.4.1_04\lib\comm.jar for Variable Value ( the ".;" is important for the entry and varies according to your JAVA_HOME)
Modifying %JC21_HOME%\samples\build_samples.bat
- Next you need to modify the compiler option in build_samples.bat
- Use editor to look for the portion "Compile Sample" and add "- target 1.1" to every statements here. A sample is listed below:
%JAVA_HOME%\bin\javac -target 1.1 %JCFLAGS% src\com\sun\javacard\samples\HelloWorld\*.java
You may proceed to test the demo codes as instrucrted in the User Guide.
I hope the above will help those who are keen to have a head start in Java Card Developemnet.

Can't use credit card

I can't use credit card to purchase any thing inside itune. Can you please do not block me. Please open it now urgently. Thank you.

Most of the people on these forums, including myself, are fellow users - you're not talking to iTunes Support here.
What happens when you try to buy something, does the 'buy' button not work, do you get any error messages ... ?
If you are getting a message to contact iTunes Support then you can do so via this link and ask them for help (we won't know why the message is appearing) : 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
If it's a different problem ... ?

Can i use debit card as a payment method on app store..if not,what else?? in case i don''t have credit card...please help

I don't think that debit cards are still accepted as a valid payment method - they are not listed on this page and there have been a number of posts recently about them being declined. You could try contacting iTunes support but I don't think that you will be able to use it : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page
If you don't have a credit card then are iTunes gift cards available in your country ? They are not available in all countries and they are country-specific (they can only be used in their country of issue), so you won't be able to use those from another country.

Oh thank god i am not the only one with this problem. It started with me on Saturday (aug 28) and still, no solution.
I live in the border with the USA so i’ve been using my itunes account with a USA debit card and then it started with that **** declined CC problem =S
The funny thing is that i’ve been trying to change countries, setting my account to Mexico and it would still say that the CC are declined. Tried 2 USA cards and 2 Mexican cards, no results =S
Wanna read something funny. I even tried to create a brand new account based in Mexico, with another email address and it still wouldn’t let me, tells me my cards are not valid……..the **** apple!!! i cannot update any app and i just got my iphone 4 on friday last week and i am dying to try new apps.
So far I’ve sent 2 emails and still no **** solution. At least i am not alone =’(

Debit cards are no longer accepted in the iTunes Store, it seems. The current valid payment methods are listed here:
http://support.apple.com/kb/HT5552
You can try contacting the iTunes Store and asking if there is any way to use your card, but they probably will tell you that it's not possible.
http://www.apple.com/emea/support/itunes/contact.html
Using a debit card in any online service where it stores your card is a bad idea in any case since if someone gains access to your account in the service, they can quickly drain your bank account. Credit cards limit your liability, as do prepaid iTunes cards.

Can I use LabVIEW to load data directly into system memory? The serial card I'm using isn't supported by NI nor does VISA recognize it. I'm using a Win32 function to read the data from the card and now I want it to go directly to system memory.

Can I use LabVIEW to load data directly into system memory from a VI? The serial card I'm using isn't supported by NI nor does VISA recognize it. I'm using a Call Library function to read the data from the card and now I want it to go directly to system memory.
The data is being received at 1Mbps.
Thanks

Two questions:
One, if it's a serial card, then presumably it gives you more serial ports, like COM3, COM4, etc. If so, VISA would see the COM ports, and not the card directly. The drivers for the card should make it so that you see the extra serial ports from the OS. If you don't see the extra COM ports from VISA, then it sounds like the drivers for the card are not installed properly. Do the extra COM ports show up in Device Manager?
Two, you said that you're using a Call Library function to get the data and you want to put it into system memory. Errr.... you just read the data and you have it in memory by definition. Are you saying you need a way to parse the data so it shows up on a graph or something?

Can I use the iPad lte with other cellular providers?

Can I use the cellular link with other cellular provider ? I don't live in the us

As I understand it (haven't seen any) If you have an AT&T version of the iPad 2, or i believe all versions of the iPad 3 have a SIM card slot, you can insert a SIM from any network.
the key is that you want to buy one that has the SIM card configuration. the older verizon only ones are built to operate on the CDMA protocol which is incompatible with most of hte world.
So having the Micro Sim option is key to international cell access.
