Action of flow controllers, temperature controllers, level controllers and pressure controllers.

For level and pressure controllers where outlet flow is controlled, the controller OP will increase with increasing PV.

• For fail safe close valves (Air to open) like level controllers, the controller is direct acting
• For fail safe open valves (Air to close) like pressure controllers, the controller is reverse acting

For level and pressure controllers where inlet flow is controlled, the controller OP will decrease with increasing PV.

• For fail safe close valves (Air to open) like level controllers, the controller is reverse acting
• For fail safe open valves (Air to close) like pressure controllers, the controller is direct acting

For flow controllers, the controller OP will decrease with increasing PV (same as the case of level/pressure controller where inlet flow is controlled).

• For fail safe close valves (Air to open) like level controllers, the controller is reverse acting
• For fail safe open valves (Air to close) like pressure controllers, the controller is direct acting

Free North American calls and incoming calls on your Android phone.

You will need

• a google voice account
• IPKall number (will explain how to get it)
• a SIP provider (will explain how to get it).
• GVcallback app

1. First get a SIP provider. Some of the suggestions are http://sip2sip.info/ and http://sip.antisip.com/account/register.php. Both are free, but I have not used it. What I used is voipraider, but may need to spend $5 to get the connection activated (you can use the $5 to make calls thru out the world).
2. Download CSIPSimple and register the SIP account created the above step. Make sure that the SIP registration in CSIPsimple is successful and active (the account will show as green and will show in the notification area of Android).
3. Now create an account using IPKall. Provide the SIP information from step 1 and you will be given a free US number. (What IPKall does is forwarding calls to the number (free US number) to the SIP account. If the SIP account is online (in Android), you will get the call. This way you can get free incoming calls on your Android.)
4. In the google voice webpage, add the IPKall number from step 3 (Tip: If Google voice does  not allow you to enter the IPKall number because it's already used, create a new IPKall number). Install GVcallback app on your Android and select the number just added as the number for call back.

That's it. If you dial somebody from your Android phone, an option will come up to dial using GVCallback. Just select that option and you will receive an incoming call. Once you accept the incoming call, it will dial the outgoing call. You can use this method to receive and make calls only using Wi-fi (no need of phone connection).

I am writing about this method so that you know such an option exist. It is your responsibility to understand the terms and conditions set forth by your phone company/google.

How to get and put cell values to excel sheet using macros?

Simple macros can be great time-savers. Here is a simple macro to create a table by fetching values from different places (but in a definite order) of a spreadsheet.
=========================================================================

Count = 0
    For i = 1 To 15
     
           date_1 = ActiveSheet.Cells(1, 8 + Count).Value
           dilbit = ActiveSheet.Cells(4, 6 + Count).Value
           lago = ActiveSheet.Cells(17, 6 + Count).Value
           percentag = ActiveSheet.Cells(29, 10 + Count).Value
         
   
           ActiveSheet.Cells(i + 36, 1).Value = date_1
           ActiveSheet.Cells(i + 36, 2).Value = dilbit
           ActiveSheet.Cells(i + 36, 3).Value = lago
           ActiveSheet.Cells(i + 36, 4).Value = percentag
         
        Count = Count + 7
           
    Next

Installing CyanogenMod 7 (mil version) ROM on Koodo LG optimus One Android phone (P500h)

Root the phone before doing this.

Download cyanogen_thunderg-ota-eng.mil-6.5.4.zip into your microSD card. CyanogenMod 7 ROM is based on Gingerbread. Install ROM Manager on your phone. Open ROM Manager and select Install ROM from SD card. Now browse to the downloaded cyanogen zip and tap it.

In the menu, check backup existing ROM (if you want to back up the current OS, highly recommended). Check the options to wipe data/cache and dalvik cache. Now Tap OK. The phone will restart and backup the files and then proceed to CM7 installation.

The phone will automatically restart after the installation (takes about 5-10 min). You will see a brand new OS on your phone. Go to settings and add your google account to synchronize contacts, mails etc.

If you want any other google applications which are not already installed with CyanogenMod 7, follow these instructions.

The same procedure can be used for installing any other android ROMs.

Install google apps on your new Android OS.

If you want any other google applications which are not already installed with your current Android ROM (like CyanogenMod 7), download apps-addon.zip. If you don't have it already, install ROM Manager on your phone. Open ROM Manager and select Install ROM from SD card. Now browse to the downloaded zip file and tap it.

In the menu, check backup existing ROM (if you want to back up the current OS, not required in this case for installing google apps). Uncheck the options to wipe data/cache and dalvik cache. Now Tap OK. The phone will restart and backup the files and then proceed to gapps installation.

Rooting Koodo LG optimus One Android phone (P500h)

This procedure will work for LG optimus One Android phone from Koodo (P500h). This may work for other LG Optimus One phones as well, but I have not tested it.

Do not use z4root to root this phone (many people suggested to use this, but didn't work for me at all). The process takes forever without any result.

Download GingerBreak-v1.20.apk (google it, I am sure you will find it). In the application settings, allow installation of non-market applications and enable "USB debugging" in Application settings>Development. Once you install the apk, you will be able to do a "Permanent root" without any fuss.

Please leave a comment, if you have success with any other methods.

If you want to go ahead and install a new ROM (for eg cyanogenMOD 7) instructions are here.
