Liquid Camera Lens

liquid lens

German research team has designed the first liquid camera lens which has no moving parts for switching between two levels of magnification. Samsung has used this technology in some of their camera cell phone models due to its small size factor and low cost of manufacturing. However professional cameras which had bulky zoom lens will get more benefit from this technology as altering the focus of these liquid lens gives the same zoom function which requires several traditional lenses to achieve. Since glass lens used today have fixed focus length, so for the zoom function two or more lenses coupled with some mechanical parts to move lens for adjustment which surely made the device bulky.

A visit at SBI ATM

June 9th, 2007 by

sbi atm machine

I have always wondered why these SBI ATM are so slow to work, the touch screen is sluggish, menu and buttons have time lag as you must have noticed when you enter the amount, it appears late on screen and what to say whole machine is lazy. Today in the evening I went to ATM and the gatekeeper was doing something behind the machine and some people were waiting. I asked what happened, is it working? Quick came the reply “yes ofcource but you have to wait for five minutes as there was a power failure and machine will take some time to boot. I kept waiting and screen flashed and I couldn’t believe at what I saw, it was a Pentium 3 ! And the way it counted onboard memory reminded me the days of 386. Now I came to the secret behind its slow working and I was laughing when I saw it loading Windows Xp ! It took almost 3 minutes showing that Xp screen and then again some 5 – 6 minutes loading some software, at last it came alive. Its so costly machine and can’t they throw in a Pentium 4 processor and some more RAM to give it a life? I know these machines don’t require much processing power as needed in fully functional computer but then why it’s slow? I have seen some other bank’s ATM using Windows98, hope it must be little faster.
