The electronics revolution shows no signs of slowing down.  When I was a youngster we had dial telephones, AM radio, and black & white TV with a tall antenna on the roof.  We did not have microwave ovens, cell phones, computers, FM radio, or GPS systems and there were no satellites.  Well hang onto your hats, because the revolution has just begun…

X-ray vision is already here… sort of.

Knowing that radio waves can pass through solid materials, in 2006, engineers at Cambridge Consultants in the UK announced they had built a device they called the Prism 200 which can detect people through a brick wall. The briefcase-sized system works by transmitting pulses of ultrawide-band radar and listening for returning echoes.

According to the company, these pulses can pass through building walls over 16 inches thick, and detect human beings behind those walls over a range of up to 50 feet. The device can only detect people when they are moving.

Erwin Biebl’s radar sensor. Biebl’s team at the Technical University of Munich in Germany has built a device that can pick up tiny motions like breathing, or even a beating heart, through a closed door. His device uses Doppler radar to sense small movements caused by the beating of a heart or the movement of the lungs as one breathes.

It’s not a big leap to envision a system worn on the head like night vision goggles.  Think of how valuable that might be in hostage situations, fire fighting, and urban warfare.

Invisibility, not just for Star Trek and Harry Potter

In 2006, a cloaking device was which worked only for microwaves, was unveiled.  Since then there have been a number of attempts to make invisibility cloaks.

Scientists have developed “metamaterials”, made with electronic components that interact with light and send it in the desired direction. The idea is to steer the light around the object. If the light goes around it then you won’t see it. So far it only works with specific bands of the electromagnetic spectrum, the goal being to create something that works with a broad band of frequencies.  The components however, must be smaller than the wavelength of the light they are steering, making them very small.

Recently, a group at the University of California, Berkeley, constructed a material that was able to bend visible light backwards for the first time, and Ulf Leonhardt at the University of St Andrews, UK, has demonstrated how metamaterials could work over a range of frequencies.

The Hong Kong University of Science and Technology in China is claiming that it has worked out how to cloak objects at a distance. They suggest using “complementary materials” which have optical properties that cancel each other out making it look as if neither material is there.

They have a long way to go, but don’t be surprised if someday you don’t see something that is right there in front of you.

Unique new sources of energy

All those gadgets…your laptop, cell phone, ipod, and all those other gadgets use electricity. Batteries run down and then what?  How about running those devices with power from your clothing?

In 2008, Zhong Lin Wang at the Georgia Institute of Technology in Atlanta wove a fabric made from zinc-oxide nanowires grown on strands of Kevlar. Each time the material is bent or squeezed, it generates a tiny current. Wang and his team found they could harvest it by coating each fiber with a film of metal.  Just plug your cell phone into your pants and start walking.

US soldiers in Iraq are using a device that could become a universal interpreter. SRI International in Menlo Park, California, has developed the system, IraqComm, used by the soldiers, packing a laptop with speech recognition and language translation software.

When someone speaks into the microphone in Arabic, the software turns the phrases into written Arabic, and then translates it into English. When the person finishes talking, the computer speaks the translation.

IraqComm’s software, and other programs like it, learn to translate by studying conversations. The software searches for statistical connections between a series of Arabic statements and English translations. Given enough examples, the software can learn grammar too. A similar system running on a hand-held PDA was developed at Carnegie Mellon University in Pittsburgh, Pennsylvania.

These programs cannot deal with free-flowing language yet. The IraqComm works well because it focuses on around 50,000 words soldiers need. The broader the subject matter, the harder it becomes for the software to distinguish the alternate meanings required in different contexts. “We’ll get there,” says SRI’s Kristin Precoda.

It probably isn’t unrealistic to assume that in a few years tourists visiting foreign lands will carry with them portable speak-into devices.

When anyone decides to quit smoking they are beginning a process that involves some very scientific principles that might seem child-like acts. But they all lead to being able to quit smoking effectively. Smoking is a psychological disorder as well as a physical one. Most people will automatically ‘light up’ after a meal because they are used to the act of smoking. Others do feel the pangs of their nicotine addiction and these people are the ones that will find it more difficult to quit smoking.

However, to say that it is impossible to stop smoking would be wrong and it would send out the wrong signals to those who are finding it already difficult to stop smoking. We would say that the process of smoking cessation is long but it is not impossible to achieve. To begin with it is important to set a date by when you will try to quit smoking. It is really necessary to set achievable dates. But not being able to achieve the goal is no excuse to take up smoking once again. This is a losers mentality to give up easily.

Once you have set your dates you should tell all your friends and relatives that you want to stop smoking. They are the most important help you can get. It is important to drill lit into your smoker buddies that you intend to quit and do not let them laugh you out of your intentions. They are most likely to do so because they cannot do what you are about to do – quit smoking. However, if you can convince some of theme to join you in your challenge there is nothing like it. Make sure you earnestly request them not to smoke in your presence nor leave their smokes lying around as this will only entice you to pick up a cigarette once again. Buy Electronic Cigarette

You are going to need all the will-power you can get. So ask your friends and relatives to help you as much as they can. You will also need to remove anything in your home and office that reminds you of smoking or even suggests it. Remove the ashtrays, cigarettes, lighters and pictures that even remotely suggest smoking to you. You need to stop thinking of lighting up completely if you want to stop smoking.

You may need some psychological helps from other things as well. It will help if you kept a pack of gum in your pocket and popped on every time you felt like a smoke. Popping a lollypop after meals is a great way to keep from putting anything else in your mouth.

Mint is another great way to keep the smoking pangs at bay. Some people have not been able to keep their minds completely off smoking and so they need props like make-believe cigarettes that they keep in their lips. They also need some help in the form of nicotine gum and skin patches if their nicotine addiction is really serious. But, quit smoking they will. However, it’s not always because of will power.

There are times when computers can behave badly. You can experience computer crashing; computer freezing and computer system can run slow. These problems are normal for any computer system today whether you like it or not. Some problems can be recognizable while others are just difficult to figure out. However, you have to try to identify want causes the problem such as computer freezing and crashing to be able to solve it properly.

Every time your computer does not succeed in responding, there is a huge probability that your computer is experiencing a problem. Computer freezing can also happen when the computer is active doing different tasks. There are times when the computer suddenly stops while saving a certain file during printing. You can try checking out the power cable if the computer screen is blank. However, there are latest computer models that have a feature wherein the screen blanks out automatically in order to save energy. Just press on keys to make the computer screen return to normal.

You can experience computer freezing due to cable disconnections. It is important to check first before making any actions. Then, you can try pressing the ‘Esc’ key if your connections are fine but still having an unresponsive computer. If computer freezing still exists, try pressing ‘Ctrl’, ‘Alt’ and ‘Del’ keys altogether. The combination of these keys lets the computer to warm boot or to restart in those DOS days. This combination has a different usage in the Windows operating system. The Close Programs box with the list of the current running programs will be presented when the ‘Ctrl’, ‘Alt’ and ‘Del’ keys are pressed. The ‘not responding’ script will then appear if Windows find any unnecessary programs. Highlight the said program name and then press the ‘End Task’. Better to save whatever data you are working on for it might be affected with the process. Using the ‘Ctrl ‘+ ‘Alt’ + ‘Del’ task is another choice to be able to restart your computer as the last resort.

’Ctrl’ + ‘Alt’ + ‘Del’ combination is used differently in Windows XP. ‘Windows Task Manager’ screen will appear when these buttons are pressed. To see the recent running programs, just click the application Tab.

There are certain times wherein Windows Task Manager Box or Close Program Box suddenly stops unexpectedly. All you need to do when this happens is a computer restart. You can press the restart button if your computer has one and if not, just turn off your computer. Then turn it on again after a few minutes. You need to wait for a several minutes before turning the computer on to allow the components to stop completely before the system restarts. Before attempting to turn off your computer, make sure you have saved any data. Although there is an AutoSave feature in most programs, it is still difficult to depend on it.

It is important to be aware of spyware and viruses that may cause compute freezing. Scanning your computer is a good idea to know the real cause of the problem.
