Recent Trends in Electronics and Communication Engineering

The world today is turning more to electronic communications such as the e-mail, Facebook and Short message System (SMS). What is your opinion of this growing trend? Everywhere we turn today, the world is crowded with people busy typing SMSes on their Nokias or iPhones or someone is staring unblinkingly at a Facebook or Yahoo page on the computer screen. Whether you like it or not, the age of Information Technology is upon us, and we can either learn new skills and adapt to this new technology, or be forever lost and stuck in the older generation. In general opinion this growing trend is the way of the future, and it brings countless benefits to mankind. In this brief blog, we will discuss few hot emerging technology in Electronics and Technology:

(I)               Remote Control Not Needed - Control Your TV with Hands

Consumers will soon be able to control their TV screens or home entertainment systems simply by waving their hand, thanks to technology developed by Toshiba's Cambridge Research Laboratory in collaboration with the University Of Cambridge Department Of Engineering. Using the Toshiba experimental TV viewers are able to interact with the display system simply by gesturing with their hand. Once the viewer is in front of the display screen, the system will invite them to take control of the display simply by raising their hand. As the system can robustly track their hand even under different lighting conditions, the visitor can enjoy controlling the on-screen cursor." The gesture interface signals the arrival of a new era in the age of wireless communication. 

 

(II)            Use Your Cellphones To Get X-Ray & MRI Scans

If you are residing in a metro, having an X-Ray or an MRI scan done is a cinch. But what if you reside in a remote location or in a village which does not the sophisticated imaging systems? A team from the Hebrew University in Israel seems to have an answer.

Using a process developed by the Jerusalem-based University, cellphones can be used to get your X-Ray, Ultrasound imaging etc., processed from a centralised location and these can be transmitted back to your remote location using the same cellular phones.

This new medical imaging system consists of two independent components connected through cellular phone technology, with a relatively simple data collection device on-site connected via cell phone to an off-site computer that processes the data and produces an image. Under this new technology developed by Rubinsky, a simple and independent data acquisition device (DAD) at a remote patient site could be connected via cellular phone technology with an advanced image reconstruction and hardware control multiserver unit at a central site, which could even be thousands of miles away from the remote site. The cellular phone technology transmits unprocessed, raw data from the patient site DAD to the central facility. This data is then returned from the central facility to the cellular phone at the remote site in the form of an image.

(III) 4G Mobile - 100 Mbps Speed Wow!

Today it’s 4G -the next generation Communication, that’s on the minds of many mobile and iPhone enthusiasts.. So let's look at what 4G could offer and where indeed we are on 4G. The most exciting aspect of the 4G phones is the download speed - expected to be 100 Mbps - and its equally awesome 50 Mbps upload speed. In terms of speed, 2.5G can offer web access at a rate of between 144 and 384 kilobits per second. 3G is even faster - anywhere between 500 Kbps and 1.5 Mbps. 4G holds the promise of routinely delivering the higher end of that transmission rate, and much faster, in some cases, up to 100 Mbps for downloading, and 50 mbps for uploading.
Naturally, such an order-of-magnitude increase in speed implies that the multimedia browsing apps will get a shot-in-the-arm. The big application that 4G will bring with such fast upload speeds is enabling higher mobile web browsing and richer mobile social networking.
