All of us would like to receive some sort of gifts during Christmas days. A survey has been conducted among the people of  UK, the US, Germany and France to know what kind of ELECTRONIC GIFTs they prefer. The survey ended up with a surprising list of 10 most wanted electronic products.

Apple products like the iPod Touch, the Magic Mouse and the iPod Nano are the most wanted electronic gifts across all the above countries.

Apple’s iPod Touch is the most wanted electronic gift item in the US, the UK and France. Music and gaming features of the device along with its e-reader facility makes Apple’s iPod Touch the most wanted electronic gift in US, the UK and France.

Products from Samsung and Canon are also at high demand.

The following are the most wanted 10 electronic products:

1. New Apple iPod touch 8GB (3G)
2. New Apple iPod touch 32GB (3G)
3. Western Digital Elements 1TB USB 2.0 External Hard Drive – Black
4. SanDisk 8GB SDHC Secure Digital Card
5. Sony BDPS360B Profile 2.0 Blu-ray Player with BD Live
6. Toshiba Regza 32AV615DB 32-inch Widescreen HD Ready LCD TV with Freeview
7. Integral USB 2.0 Single Slot SD / SDHC Card Reader
8. New Apple iPod classic 160GB – Black
9. Seagate Expansions 1TB External Desktop USB 2.0 Hard Drive
10. LG 22LH2000 22-inch Widescreen HD Ready LCD TV with Freeview Black

Wireless brain control is the realization of the dream of controlling devices at the speed of thought. That is you can start your car by thinking about starting it. Brain control is achieved by controlling wireless robotic devices, like robotic arms wirelessly, based on the electronic signals generated by a chip implanted in our brain. The brain control chip has hair like electrodes picking up the neural signals generated by our brain and converting them into electrical impulses.

(Fig i)Concept of wireless brain control

The above figure shows a man controlling his wheel chair with his brain. He has a brain chip implanted in his brain. This brain chip picks up the brain signals and controls the robotic control system that moves his wheel chair, so that he can move in any direction he thinks about.

Structure of a brain chip:

(Fig ii) Brain chip with electrodes.

The above figure shows a typical brain chip. It has hair like electrodes which are used to pick up neural signal that are produced by our brain when we think about something. These brain signals are converted into electrical impulses by the chip implanted in the brain.

(Fig iii)Size of a brain chip.

This kind of tiny brain chips are implanted in our brain sent out control signals to the robotic arms or other kind of robotic devices. The robotic devices can be made to do anything!

What is it now?

(Fig v)A monkey controlling a robotic arm with the help of brain chip.

Scientists have successfully implanted brain chips in monkeys. Those monkeys could control robotic arms by just thinking about it.

Application:

Technological advancements like wireless brain control is a great help to physically challenged people.

So let’s hope for the best form the dedicated team behind the research.

A web cam, mirror attached projector, and a smart mobile phone with internet connection is all what we need to create sixth sense using internet. Mobile phone with internet connection is kept in the pocket. The web cam and the mirror attached projector are interconnected using a string which goes around our neck. Web cam detects the motion of our fingers wound with red, green, blue and yellow colour bands.

How does it work?

Suppose we would like to email our friend. In order to do that we have to move our colour band wound fingers in a predefined manner. The web cam detects the finger motion and is compared with the predefined and stored motion patterns.

Finger motion patterns are mapped with specific commands. The commands are executed when the web cam detects a finger motion pattern and is found matching with the stored patterns. Colour bands are used for the accurate definition and detection of the finger motion patterns.

As soon as the web cam detects a matching finger motion pattern, you can project your computer’s or mobile phone’s screen on to any surface that you want. It can be:

(i)Screen projected on hand

(ii) Screen projected on wall

(iii) Screen projected on table

Now we can type and send the email! So simple isn’t it?

In the same fashion you can take pictures using your mobile phone with your colour band wearing finger motions. MNCs have taken up this idea and have started developing stuff like WUW (Wear Your Word) etc.

Scientists at the University of Waterloo, Canada, have created a new lithium battery that can store and deliver more than three time the power of conventional batteries. The study demonstrated robust electrochemical performance of a lithium-sulphur battery.

Sulphur is cheaper than many other materials currently used in lithium batteries. It has always showed great promise as the ideal material for a safe, low cost, long lasting rechargeable battery, needed for energy storage and transportation in a low carbon emission energy economy.

During the research, the most difficult part was to enable a reversible electrochemical reaction at high current rates, as the electrically-active sulphur needs to remain in an intimate contact with a conductor, such as carbon. Using a nanoscale method, the team assembled a structure of 6.5 nanometre thick carbon rods separated by some empty channels. To fill the void, heated and melted sulphur was used.

Carbon microfibres spanning the empty channels kept the voids open and prevented collapse of the structure. All the spaces were uniformly filled with sulphur, exposing an enormous surface area of the active element to carbon. This composite material can supply up to nearly 80 percent of the theoretical capacity of sulphur, which is three times the energy density of lithium transition metal oxide cathodes, at reasonable rates with good cycling stability.

Think of knowing the time by just moving your hands over your bed sheet at night. The fact that you can know the time even without opening your eyes makes you feel great about this new concept? Hey, this is not just a dream. Wake up, its goanna be a reality! This is what time showing bed sheets talk about.

There are many different sources from which the “PRECIOUS” time could be known. Watches are the traditional devices that we commonly use to be aware of the minutes and seconds. Clocks hanging on the walls remind us about our duties. At office our PC’s and Laptops tell us about the deadlines, important meetings and the party tonight! The digital and analogue clock utilities in our mobile phones help us to be on time. Mobile phones are increasingly used as a time showing device, in such a way that watches are getting replaced!

How it works?

The Melted Clock is a haptic, touch sensitive alarm clock, with integrated speakers and controls all embedded into your sheet. Sounds a bit complicated, but parts of this are certainly possible today. There are three control icons on the sheet, as well as others on the side of the sheet. You can tell the time easily by using your hands or your eyes.

This clock uses silicone and electroactive polymer, which is used in artificial muscles, to work. The slat will expand and lift up the silicone. This means that the numbers and the clock are quite soft and won’t really bother you too much in bed.

A car alarm system prevents our costly cars from being stolen. A typical car alarm system sounds loudly when any one try to steal our car. The most important thing is to draw the attention of the people nearby, during an attempt of theft. If you want to deter your local thief without spending hundreds on a car security alarm? Here you can read about a CAR ALARM SIMULATOR. LED with ‘realistic-appearing’ flash sequence simulates active car alarm system.

Ingeniously simple circuit can tell if your car is running or not by detecting the voltage difference when the car is on and off.  This occurs because when your car is running the Alternator puts a out a voltage a little bit higher than when the car is off.
