Does anyone know how to calculate the impedance using waveforms

does anyone know how to calculate the impedance using waveforms?

the waveforms represent the voltage and current values across a capacitive load. I am trying to find out if there is a way to do automatic calculations using the inputs from the waveforms
Hopefully a single sinusoid tone. Otherwise things get really interesting. Also know that impedance is based on the frequency. I'll have to dig into this again. I have not had to calculate an impedance in well over 10 years.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Does anyone know how to reset the fan on a MacBook Pro 13-inch (Late 2011) to it's factory setting speed (Maybe Terminal may help?)

I have a late-2011 13-inch MacBook Pro running OS X Yosemite. (Standard configuration).
My problem is that I downloaded a fan control application and it worked perfectly, but it started to get annoying so I deleted it.
Does anyone know how to reset the fan speed back to factory settings (Maybe a command in terminal?)

OB52 Posting Period Close: Does anyone know how to automate the close?

Does anyone know how to automate the FI Period Close (trans code OB52)? Currently, the business users go into the screen and open and close any periods manually. For the MM period close, we are able to do so because we found the program to use in the batch job. For some reason, the FI side shows the program SAPL0F00 but this is only a view and will not allow a batch job to be created. Does anyone know of the actual program used for the FI period close?

Use program RFPERIOD_OPEN. It may help. For further details you may check the following thread.

How to program a midi foot controller on Mainstage? Does anyone knows how to program the foot controller with exclusive solo channel in order not to dance "tip tap" while from clean guitar I go to crunch or solo? How to do this programming on Mainstage?

How to program a midi foot controller on Mainstage? Does anyone knows how to program the foot controller with exclusive solo channel in order not to dance "tip tap" while from clean guitar I go to crunch or solo? How to do this programming on Mainstage?
I basically managed to learn how to invert parameters which allows me to be as default in the clean guitar channel and if I switch the first button on the midi foot controller I switch to crunch, but at this point I tryied so hard to programm the second and third button to switch, only through a button in one step, to a third channel for distorsion or a 4th channel for solo guitar but I couldn't figured out how this work can be done!
I would appreciate if anyone could help or share this experience with others who are experiencing the same problem.
Cheers.

If restoring using your backup didn't work, you'll have to save as much of your data as you can (import your photos to your computer, sync your contacts and other data with iCloud, email things like Notes and Voice Memos to yourself, sync with iTunes to transfer all your purchases, etc.) and then restore it as new without using your backup.

I recently changed my apple ID but my previous apple ID is associated with my icloud account. I'm setting up my new iphone 6 and cannot complete the set up until I can sync my icloud account. Does anyone know how to change the icloud id?

Do the following:
Make sure you are signed into iMessage and FaceTime with your current ID. If they are signed into the old ID, go to Settings>Messages>Send & Receive and Settings>FaceTime, tap the ID, sign out, then sign back in with your current ID.
Then temporarily recreate the old ID by going to https://appleid.apple.com, click Manage my Apple ID and sign in with your current iCloud ID. Click edit next to the primary email account, change it back to your old email address and save the change. (You should not have to verify the old email account so it doesn’t matter if you no longer have access to it.) Now go to Settings>iCloud, turn off Find My iPhone and enter your current password when prompted (even though it prompts you for the password for your old ID). Then go to Settings>iCloud, tap Sign Out and choose Delete from My iPhone when prompted (your iCloud data will still be in iCloud). Next, go back to https://appleid.apple.com and change your primary email address back to the way it was. Now you can go to Settings>iCloud and sign back in with your current iCloud ID and password (your data will download back to your phone).

HT4356 I have two printers on my network. Does anyone know how to change the printer nomenclature - Officejet Pro 8600 (0B54AF) to a recognizable name...like Brad's Office?

I have two printers on my network. Does anyone know how to change the printer nomenclature - Officejet Pro 8600 (0B54AF) to a recognizable name...like Brad's Office when you use Airprint?

You would have to change that in the printer's settings on the printer, if that option is offered by the manufacturer. The iPhone just finds printers on the network and uses the name they have given themselves or that were given to them when they were set up.

Hello,
Exactly which USB device are you referring to? Is the device a NI product?
The Product ID for National Instruments DAQPad-6020E is 0x12C0. The USB vendor ID is 0x3923. This is a 16-bit hexadecimal number(1093) (that is decimal 4243).
Also, here's a document on our website that will help you in configuring NI-VISA to control your USB device:
