Cell Phone Radiation Facts

To begin with, let me share an interesting revelation with regards to cell phone radiation. Not only cell phones but the cell phone signals emitted by the towers of various service providers are responsible for the transmission of a lot of radiation into the atmosphere. This is one of the most significant reasons behind the fast dwindling number of birds and the recent mass deaths of avians as the radiation from these service towers is causing more and more flight birds to develop cancer, resulting in their mass demise! Stunned? Read more about dangers of cell phone towers to know more. As far as cell phone radiation facts are concerned, there's more to come in the subsequent paragraphs.

Random Cell Phone Radiation Facts

Nowadays, with the spurt in information and rumors about cell phone radiations and the resultant harmful effects on users and the environment in general, people have suddenly started showing concern over knowing more about cell phone radiation levels and ways to incorporate cell phone radiation protection measures for themselves and their surroundings. Since knowledge about the enemy is the best and first weapon we have against it, let's take a look at some serious facts of radiation from cell phones and learn more about the effects of cell phone radiation.

Signals emitted by modulated cell phones have been scientifically proved to drain the surface of the brain of vital calcium, thereby, weakening the brain membrane and making the brain vulnerable to various undesirable biological conditions such as cancerous growths.
The brain is where the damage starts but it is not the only part of the body that gets adversely affected by cell phone radiations. Damage to retina, joints, muscles, nerves, skin and various other tissues followes close on the heels of brain damage. Too much use of cell phones also results in a decreased white blood cell count in the body, lowering the body's defense against diseases.
The radiations that are emitted by cell phones have a much deeper effect upon our biology than just attacking and degenerating various organs. Exposure to these radiations, over a long period of time, eventually leads to degeneration of our DNA structure and robs the DNA of their ability to repair themselves.
Mobile phone radiation can also lead to behavioral and psychological issues in children whose brains are still in the developmental stage.
Long term or extensive exposure to cell phone radiations is also known to cause fertility issues.
Although the rumor about cooking an egg by placing it between two activated cell phones may just be an urban legend, the modulated radio waves emitted by cell phones do have the ability to fry our brain cells. These modulated radio waves cause the neurons of the brain to leak, inducing unnecessary and harmful nerve impulses that can lead to sleep disturbances, loss of concentration, mental fogginess, migraine and stress headaches and seizures.
The same mechanism that is mentioned in the preceding point causes dermal and cardiac membranes to leak, leading to various skin infections and serious heart conditions such as abnormal palpitation and cardiac arrhythmia.
Compared to modulated radio waves, unmodulated radio waves are a lot safer, their only effect on the body upon long term exposure, being an increase in the body temperature.
The modulated radiations of cell phones also lead to the leakage of hemoglobin from blood cells. Extensive exposure leads to a heightened vulnerability to asthma and various allergies due to accentuation of the production of histamines in mast cells.
Cell phone radiation leads to various digestive and metabolic abnormalities and is an active agent in raising the harmful cholesterol levels in blood.
These radiations also put a lot of pressure on our endocrine system, leading to abnormal function of the glands.

How Does GPS Tracking Work?

0 comments Posted by 505 at 6:18 AM

The Global Positioning System is a piece of mastery and there is no need to exaggerate on how effective this has been in recent years. It was first used only for military personnel for operations. It has now been extended to the public with the feature of Standard Positioning Service at their disposal at no fee whatsoever and no ban on its use. So how does a GPS tracking system work? It uses microwave signals that are directed towards GPS devices that give users information on their direction, time, location and even speed. It can give you real time feedback to monitor and track present day and time events and movement, making it a great way of keeping an eye on anything that moves or spans out across a particular distance.

It is definitely an impressive work of art, where the Internet and one's cell phone uses stored data in databases, where the GPS receiver unit feeds on information about an object and its whereabouts. You must have seen these in cars and other vehicles equipped with a GPS tracking device using a screen picturing a map that marks in and provides real time mapping and tracking as one is on the move. Many people have made good use of this technological breakthrough, which we will find out soon enough in how they use it in everyday doings.

How Does GPS Tracking Work in Day-to-Day Routines?

Now that we have an idea on how do GPS devices work, we now look at ways on how you can use this service in many areas in your daily life.

Road trips are made easy with information fed into the system on campsite locations, landmarks, stop in eating areas, drive in food joints and so on, making traveling on the road a piece of cake. To make a good decision about which GPS works best for you, go to how to choose a GPS navigation system for help.
If you have a pet that you need to keep an eye on with the problem of him/her running off from home, GPS collars work best in tracking them down.
The old and aged can tend to wander off aimlessly with you panicking in the process. GPS devices come in different varieties to help you keep a track on them.
If you end up stranded somewhere either in known or unknown areas, and you need immediate help, a GPS system works great for help finding you sooner and faster.
You can tag on these devices to items during travel to keep track on where they are if ever they get misplaced or offloaded.
Groups that go on trips should carry these GPS devices to help find each other especially if some were to wander off on their own.
Keeping a tab on children using a GPS device could be a great investment for those kids who tend to disappear when unsupervised.
Makes locations and new areas in your town easy to find through the GPS.

How Does GPS on Phones Work?

The dynamics that go behind a GPS tracking system is that it functions using the earth's 20 plus satellites along with their ground stations. It is under surveillance and is controlled by the US Department of Defense with it being funded as well by them. There is a process called as trilateration which cellphones function through when it comes to GPS enabled mobiles. To help the GPS track your location before giving you the information you need, it first bounces off the closest satellites or cell phone towers around you, and pinpoints your location, knowing exactly where you are and which location you now need to head towards. There is a lot that goes into how the signals have to constantly pick up what satellites are emitting, using specialized receivers, that is GPS devices, to help track down the person's location before directing them to other areas. To bring the process around full circle it is important to understand how these signals are constantly bumping off into the atmosphere where they are reined in before being made use of by the user.

Wireless Router Range Extender

0 comments Posted by 505 at 6:06 AM

This limitation is inherited from the fact that radio waves are used as the communication medium. Radio waves, being electromagnetic radiation, drop in intensity according to the inverse square law of electromagnetism with increasing distance. Physical obstructions also create blind spots, where the WiFi signal cannot reach. An effective solution to this problem of poor range and WiFi signal reception is the use of wireless router range extender. The aim of writing this Buzzle article is to introduce you to wireless range extenders or wireless signal boosters as they are known. A listing of the best wireless router range boosters in the market today, presented below will make it easy for you to choose one.

How Does a Wireless Range Extender Work?

Even if you have the fastest wireless router installed, it has a limited range, beyond which, no matter what you do, it's going to provide a weak signal. With the use of a wireless range extender, you can go beyond the periphery of your current wireless Internet access coverage range. How does this device work to achieve this objective? Let me provide a basic explanation.

Firstly, a wireless ranger booster or wireless signal booster is a transreceiver. It receives the weak WiFi signal transmitted by the wireless router, amplifies it and retransmits it over a wider range. The original signal from the router is left untouched by the range extender, besides increasing its signal strength. Thus in a way, a range extender, repeats the signal and broadcasts it further. That's why these signals are known as wireless repeaters. Many university campuses and industrial settings have a such wireless repeaters installed to ensure that there are no blind spots left, with weak WiFi signals reception. So if anybody asks you about how to extend wireless router range beyond existing limits, you know what to recommend.

Choosing a Wireless Range Extender

A glance through wireless router reviews will reveal the great variety of products available in this consumer electronics segment. Similarly, there is a great variety of range extenders available in the market, for you to choose from. Let me discuss some of the features to look out for when shopping for a range extender.

One of the most important factors to be considered is compatibility. Your existing router and other equipment needs to be compatible with the range extender you purchase. Secondly, it is recommended that you go for a 802.11n networking standard based extender as it provides the greatest transmission speeds overall. Look for security features that include WPA2 encryption and a firewall. Choose any one which suits your overall budget and requirements.

Best Wireless Router Range Extender (2011)

So now that you know how to boost wireless router range using extenders, the next question which arises is which are the best wireless range extenders that you could choose. Here are some of the best signal boosters in the market today.

Hawking HWREN1 Hi-Gain Wireless-300N Range Extender ($68.99)
Netgear Universal WiFi Range Extender WN2000RPT ($69.99)

New iPad Release Date

0 comments Posted by 505 at 5:49 AM

Who knew that a mere tablet PC could endow you with a fluttering peek of what does it feel like to hold the entire world in your hands? Who had an idea that it'd shush those inutile evaluators who harbored suspicion about it being a perfect replacement for laptops? While Android is having its nose to grindstone, having set out more than 80 tablets to kill the miracle called theApple iPad, the developers of iPad repose in snugness, for the next generation iPad, the Apple iPad 2, is already seen in the cards. On January 27, 2010, the Apple fever among tech-savvies took a flight, for the first generation iPad broke through and how! Needless to say, it became a madness, a trend, a course, and of course, a must-have for every Apple lover. People anxiously waited for it to hit the stores, so that only once they could hold the beautiful king of tablets in their palm. To kick the bewilderment up a notch, that's happening again. Yes, you'll soon have in hand the new iPad, release date (2011) of which is set sometime in spring. That is to say, it's just round the corner, if the juicy iPad 2 rumors are to be presumed true. But what to expect from the new iPad 2? Today, let's draw something out of the interesting back-fence talks about the miracle that is soon going to take people's breaths away.

What is the New iPad Release Date

Rumors, rumors. Speculations on the Apple iPad 2 release date suggest that since iPad is being subjected to a considerable rise in the competition within the tablet market, it could launch the new iPad 2 quite soon. Tablets such as Motorola Xoom and Samsung Galaxy Tab (refer to Galaxy Tab vs iPad) have started to develop a good fan base, and are already being christened as the 'iPad killers'. Hence, it is extremely important for Apple to treat its fans with the iPad 2 at the earliest.

Another reason for Apple devotees to fervently expect the company to pass the word regarding when is the new iPad coming out is that since the first generation iPad was released in January, 2010 and shipped during Spring, chances are, something of similar sort could happen this year too. Hey, it's almost spring, innit? Tech veterans speak of the new iPad as something which is earnestly awaited, and hence, the sooner Apple launches it, the better it is for the company. After all, distractions, my friends, aren't good, or are they?

New iPad 2: What to Expect

If the buzz that's zooming with regards to when is iPad 2 coming out and what's new in it is to be believed, then you have all the reasons to buy this beautiful tablet, for Apple developers have read minds of their users. There was a reason the iPad market witnessed turbulence. It was because of the absence of a camera in the first generation iPad. Well, to save itself from witnessing users switching loyalties, rumors rife that the iPad 2 might have two cameras (8 MP or 10.2 MP back camera, and a front camera for video conferencing). That is believed to not only kick the iPad experience up a notch, but will also get Apple maximum hold of video conferencing-freak customers.

Solar Power Pros and Cons

0 comments Posted by 505 at 5:10 AM

I guess no one really remembered what Thomas Edison quoted years ago! Today we are suffering from a situation wherein we have to pay high prices for gas and diesel because these resources are getting depleted at a much more faster rate than they are consumed! Although, people are switching to renewable energy sources like solar energy, however, it is still not enough! As we all know, solar power is the production of electricity through the heat generated from the sunlight. With people trying hard enough to reduce global warming, they are looking for various ways through which energy can be saved and global warming can be controlled. Using solar energy in this case, seems to solve a lot of issues, which is why more and more people are trying to know about the solar power pros and cons. If you are one of them, then reading this article further would help you understand why using solar energy is better not only for saving the earth, but also saving your expenses in the long term. As different people consider different things before adapting a new technique, we shall discuss about both, the advantages and disadvantages of solar energy. Read on…

Solar Power Advantages

Like every coin has two sides, so does solar power! The best advantage of solar energy is that it is renewable. Meaning you can harness it once and use it again and again over a period of time…and the best part is that you don't have to pay to the sun every time for shining on you! :) Have a look at the solar power benefits mentioned below.

Solar power can be used at any part of the world where there is sunlight. Therefore, even the remote parts of the world like the mountain regions, where electricity cannot be generated otherwise, can use solar energy to generate electricity.
You don't need a utility connection and pay the utility bills to them for electricity. Once you have installed the solar power, you can avail its benefits without having to worry about the utility bills or power outage.
People are switching to using solar power because it does not cause pollution while generating electricity. Unlike the conventional electricity production which releases carbon dioxide, mercury and other harmful gases like nitrous oxide and sulfur dioxide, using solar power for generating electricity is a good option to control pollution.
Solar power also gives you long term financial advantages as it is the initial investment only that you should be worried about. Once the solar installation is done, you can use electricity without any further costs and expenses.
Solar energy is used not only for heating purposes, there are many solar appliances that can be used for additional purposes like cooking and operating various other appliances both at work and home.
Unlike other sources of generating electricity which end up generating more noise than electricity, you can be assured that a solar power system would do its work quietly without any worries about noise, harmful gases and fumes. You also don't have to worry about changing their parts every now and them. Once you have installed a solar power system, all you need to do is relax!

Solar Power Disadvantages

As we are discussing about the solar power pros and cons, after discussing the pros of solar power, you must also be aware of the disadvantages of solar energy. We have had a look at the benefits so far, let us have a look at the solar power drawbacks now!

If you are looking for short term benefits instead of long term, then installing a solar power system could prove to be costlier than the 'standard' source of generating electricity! This can be due to the installation of solar panels which can be very expensive.
Solar power can be used only where there is abundance of sunlight. If you live in a area where there is hardly any sunlight, then solar power isn't a good option for you.
The solar panels may contain toxic elements like lead, which can prove to be harmful to the health.
The solar panels consists pf photo voltaic cells. These cells can get affected by the pollution in the environment or overexposure to the sunlight. This can reduce the efficiency and effectiveness of the solar power system.

How is GPS Changing People?

Is GPS Dangerous?
Like any new technology, GPS has its drawbacks. You have probably had at least one experience with a driver who swerves all over the road, speeding up or slowing down without warning, and is a danger to everyone in the vicinity, all because his attention is locked on the GPS navigator attached to the windshield. For those who aren’t lucky enough to have these systems in our vehicles, it seems strange that people would even want to have something like a miniature computer screen constantly obstructing their view of the road. This is becoming more and more common, though, and with GPS receivers built into cell phones, some drivers don’t even have the luxury of a map attached to their windshield. Instead, they drive with one hand, continually looking down at the maps on their phones, almost as if they expect the phone to drive for them, too.

The Unfounded Fear of Progress
Those who express such sentiments as these about new technologies are often labeled reactionaries and curmudgeons, and rightly so. After all, the new technologies that have made our lives better have often started out life in the midst of fear and criticism. Many people resisted microwave ovens at first due to a fear of their radiation output. Similar concerns were voiced about cell phones, which have since become an indispensable feature of contemporary life. So perhaps using GPS for everything only seems dangerous now; when this relatively new phenomenon has had some time to become more integrated with daily life, we will scarcely give it a second thought, and will laugh at the notion that we once thought it could be dangerous.

How Technology Changes People
However exaggerated these fears of new technology, it is perhaps fair to ask about their other effects on our lives. Maybe new technologies are not always as dangerous as we make them out to be, but they do have an undeniable and indelible effect on who we are as individuals. Take the microwave as an example. Today, people who are young or single can almost entirely avoid having to learn how to cook for themselves. Almost everything is available in a microwavable version, and there are even "cookbooks" that claim to instruct people how to use the microwave to their culinary advantage. Social networking is another popular example of this phenomenon: with the ability to interact online, interacting in person has become almost obsolete, and as a result far fewer people know how to do it.

How GPS Could Change People
One could argue all day about whether these changes are good or bad, and in the end it might be futile to have the discussion, because there are both good and bad aspects to any major social change. That the changes exist, though, is certain, and it would be truly foolish to claim that people have not changed as a result of these new technologies. In the case of GPS technology, the question that needs to be asked is: how are people changing as a result? If you or anyone you know has a smart phone with an excellent navigation system, you probably already know the answer to this question. People are coming to rely on these portable navigation systems in more and more instances. Those who once knew their way around a particular city, for example, may be forgetting how to navigate without their GPS systems.

Light Microscope

0 comments Posted by 505 at 2:35 AM

If you are wondering what is a compound light microscope?, then we will like to tell you that it is a light microscope which uses more than one lens to magnify the image. Light microscopes are of various types; some simple ones, like the one you have in your laboratory, or the more complex ones which are used by biologists. Magnification and resolution are two important features of a microscope. We will know more about these, but before that let us know a bit about the history of microscopes.

Zacharias Jansen of Holland can be credited with inventing the first microscope. His microscope had two lenses, one that magnified the image and another which further magnified the image produced by the first. The lens close to the eye was a bi-convex lens and the one farther from the eye was a plano-convex lens. These two lenses were mounted on two tubes which were placed in such a way that sliding one of the tubes altered the focus of the microscope.

In 17th century, Anton von Leeuwenhoek and Robert Hooke researched more on this subject and they discovered that to increase the magnification power of the microscope, the focal length had to be reduced. Leeuwenhoek's microscope was a single glass lens, whereas Robert Hooke's was a compound microscope having two lenses. With time, high quality lenses were used in microscopes and both, magnification power and resolution improved. Magnification and resolution are the two factors that determine the quality of a microscope. Magnification is the degree to which a sample is magnified when placed under a microscope. The light microscope magnification is calculated as

Magnification = Objective lens × Eyepiece lens

Resolution is the ability to distinguish between two tiny objects or a measure to which we get a detailed image.

Light Microscope Parts and Functions

Eyepiece lens: This is the lens from where you look at the image. The power of these lenses is around 10x.

Tube: The tube connects the eyepiece to the objective lenses. We will know about objective lenses later on.

Illuminator: To observe the specimen carefully, natural light may not be sufficient, so a microscope has a small bulb and the light from this bulb is redirected on the specimen by the means of a mounted mirror.

Base: The base is used to stabilize the microscope and makes it easy to move the microscope from one place to another.

Objective lens: The objective lenses are attached to the end of the tube. Normally, three to four objective lenses can be found in a microscope. The magnifying power of these lenses is in the range of 4X to 100 X.

Diaphragm: A diaphragm is used to alter the intensity of light projected on the interface.

Adjustment Knobs: The adjustment knobs help in observing the specimen in a better way, that is, they enable the user to get a highly magnified image. There are two adjustment knobs in a microscope. A coarse adjustment knob and a fine adjustment knob. The coarse adjustment knob helps in bringing the specimen in the right plane of focus, whereas the fine adjusting knob helps in clarifying a partially focused image.

Electron Microscope

Light microscopes are the oldest microscopes that are still being used, but the advances in science and technology has fueled the human desire to know more about his/her environment. There are certain organisms that are so small that they cannot be seen under a light microscope. To observe these organisms, an electron microscope is used. An electron microscope has a better resolution and greater magnifying power as compared to a light microscope. There are some differences between a light microscope and an electron microscope, let us take a look at them.

Light Microscope vs Electron Microscope

S.no.	Light Microscope	Electron Microscope
1	Affordable ($150 to $800)	Expensive (More than $1 50,000)
2	Easy to operate and carry	Requires expertize to use
3	Easy sample preparation	Sample preparation takes time
4	Original color of sample is maintained	Images are produced in black & white
5	Samples used can be living or dead	Only dead samples are used
6	Magnification power is 2000X	Magnification power is over 500,000X

High Efficiency Solar Panels

0 comments Posted by 505 at 12:46 PM

Nanotechnology is an integral part of most of the research work carried out in today's world. It is also used in the research and development of solar panels to make them efficient. Basic technological information pertaining to solar panels without getting into the details about nanotechnology is presented in this article.

Overview of High Efficiency Solar Panels

The multi-junction solar cells contain thin films manufactured by making use of the technology of molecular beam epitaxy. The metalorganic vapour phase epitaxy can also be used in the production these solar cells. Different semiconductors have their specific value of band gap energy. A semiconductors's band gap energy value allows it to absorb a certain light in an efficient way. That is why,0 the choice of an appropriate semiconductors matters a lot in the application of this technology. This is because maximum amount of energy has to be absorbed to make the solar cells efficient. The details, in brief, of the underlying technologies used for these solar panels (i.e. the 'Molecular beam epitaxy' and 'Metalorganic vapour phase epitaxy') is given below, in the hope that the information may prove useful to you.

Molecular Beam Epitaxy
It is one of the techniques used in depositing single crystals on to the substrate. This technique was developed in the 1960s in 'Bell Telephone Laboratories'. Alfred Y. Cho and J. R. Arthur were the ones who invented this technique. The single crystals are known for their unbroken edges. As the name suggests, 'epitaxy' is the technique used for manufacturing these solar cells. In the process of epitaxy, a monocrystalline substrate is used and monocrystalline film is deposited on it. A high vacuum environment is required for conducting the process of molecular beam epitaxy. The deposition rate of monocrystalline film in this method is very slow; it is less than 1000 nm per hour. The sublimation and condensation process of pure elements like arsenic and gallium is used to form wafers of these solar cells.

Metalorganic Vapour Phase Epitaxy
In the Metalorganic Vapour Phase Epitaxy, a chemical reaction is used. Use of chemical reaction in this method is opposed to the physical deposition technique (used in Molecular Beam Epitaxy) applied in 'Metalorganic Vapour Phase Epitaxy'. Chemical vapour deposition is the process used in Metalorganic Vapour Phase Epitaxy. The metal hydrides and metalorganic compounds which contain the necessary elements for manufacturing solar cells take part in a surface reaction. The pyrolysis process helps in the decomposition of these compounds and finally the pure elements are deposited on the substrate layer being used. Unlike the vacuum used for Molecular Beam Epitaxy, the gas medium is used during this process. The pressure that is maintained during this chemical process ranges from 2-100 kPa (Kilo Pascal).

Solar Panel Efficiency

The sunlight-to-electricity conversion efficiency is taken into account in determining whether a product is good enough to be used commercially. In the 1980s, conversion rate was around 16%' since then, the solar panel efficiency has gradually increased. Today, this number has gone up to 40%. Some of the companies in research and development of these modern solar panels claim to provide these equipments at an installation cost of $3 per watt. There are few companies in the market that offer solar panels with higher efficiency than the traditional ones. The solar panel efficiency comparison should be carried out so as to find the best product available in the market.

A waterproof iPhone case is a must for all iPhone owners because one of the biggest concerns of Apple iPhone owners is protecting the device from all sorts of physical damage. This is a rather expensive gadget, and no one likes to see their costly electronic devices get affected by various external factors. One of the biggest dangers to all such electronics is undoubtedly water, and this has the ability to completely short circuit and ruin your iPhone.One way to protect your iPhone from water is to keep it in your pockets at all times, and take great care to ensure that it is never exposed to water. But sometimes this is not possible, and no matter how hard you try, you cannot avoid every single instance of this occurring. For all you know you may be caught in an unexpected spell of rain, or someone might spill a glass of water on the device or you may just place your phone is a small pool of water on a table. It is for times like these that a waterproof iPhone case comes in handy, especially if you do not have iPhone insurance.
Best Waterproof iPhone Case
The best waterproof cases that you use may not be the most aesthetically pleasing and attractive to look at, but they certainly know how to get the job done. There is absolutely nothing wrong with wanting to protect your phone from water and other weather conditions, and it is alright if this comes at the cost of diminishing the visual appeal of the device. You can choose when to remove the case so this is something you can learn to live with.
There are a number of cool iPhone cases for you to choose from, and you will definitely find some waterproof cases that look great as well.

Next Generation iPhone 5

0 comments Posted by 505 at 9:39 AM

Apple launched iPhone 4G on 24th June, 2010, – which was exactly a year after it launched its previous version – the iPhone 3GS (which was launched on 19th June, 2009). A similar trend was seen earlier, when iPhone 3GS was launched a year after its predecessor – the iPhone 3G (which was launched on 11th July, 2008.) Come 2011, everybody has their eyes on the next generation iPhone 5G as a year has passed since the release of iPhone 4G. If the iPhone 5 rumors making rounds of the cyberspace and tech arena are to be believed, Apple’s smartphone of the next generation – iPhone 5, is slated for a grand release in the 2nd quarter of the year. Before we move on to the details about when is the iPhone 5 coming out, let’s have a sneak peek at some features that are expected in it.

Next Generation iPhone 5 Features

With Apple Inc. yet to reveal anything about the launch and features of the new iPhone 5, most of our knowledge about the same is based on rumors and speculations about it. It’s but obvious that Apple will put in some efforts to make sure that none of the iPhone 4G problems are repeated in its next generation iPhone. But it will have quite a few new features as well. If the sources are to be believed, the new iPhone will be armed with a A5 Processor – as opposed to the A4 Processor that was used in its predecessor, which will add to its speed by a significant extent. At the same time, it is expected to facilitate Near Field Communication (NFC) – a system which allows the device to interact with other devices around it.

Similarly, an improved camera and 3G enabled video chat is also expected to feature in iPhone 5G features list. This time around, Apple can’t afford to miss out on a camera with more megapixels – especially with smartphones boasting of 8MP and 12 MP becoming more and more common. Other features like 4G connectivity, a larger screen, more carriers to choose from, a new operating system, are also expected in the new iPhone, alongside all the amazing features that its predecessor boasts of. Most important of all, Apple is expected to put in a great deal of effort in making sure that the antenna-gate fiasco – which did hamper the brand iPhone to a certain extent, doesn’t surface again.

Next Generation iPhone 5 Release Date

It would be least surprising to see Apple Inc. push for an early release of iPhone 5G to revert the damage caused to brand iPhone by the antenna-gate fiasco of iPhone 4G. At the same time, it is quite unlikely that Apple will change the routine of releasing iPhone versions in month of June – July – something that it has been doing right from the first Apple iPhone. If reverting the damage is what Apple intends to do, it may even launch iPhone 5G 2011 in May itself. The one year period between the release of two iPhone versions is of strategic importance considering that this period allows the users to settle down with the said version. Even the users have got used to this practice – with millions of people looking forward for the month of June – July to own the new version of Apple iPhone.

New Wind power iPhone charger

Now you can charge your iPhones using wind chargers. The iFan basically is a modified PC fan erected into a rubber-made iPhones case. According to iFan designer, Tjeerd Veenhoven, it took him six hours to recharge his iPhone using
iFan.

He also said that in near future he will redesign iFan blades to improve the charging speed. Its cool and eco-friendly. I think all cell chargers should like this.

Oil change reignites debate over GPS trackers

Oil change reignites debate over GPS trackers

The wire was attached to a strange magnetic device that puzzled Afifi and the mechanic. They freed it from the car and posted images of it online, asking for help in identifying it.

Two days later, FBI agents arrived at Afifi's Santa Clara apartment and demanded the return of their property — a global positioning system tracking device now at the center of a raging legal debate over privacy rights.

One federal judge wrote that the widespread use of the device was straight out of George Orwell's novel, "1984".

"By holding that this kind of surveillance doesn't impair an individual's reasonable expectation of privacy, the panel hands the government the power to track the movements of every one of us, every day of our lives," wrote Alex Kozinski, the chief judge of the 9th U.S. Circuit Court of Appeals, in a blistering dissent in which a three-judge panel from his court ruled that search warrants weren't necessary for GPStracking.

But other federal and state courts have come to the opposite conclusion.

Law enforcement advocates for the devices say GPS can eliminate time-consuming stakeouts and old-fashioned "tails" with unmarked police cars. The technology had a starring role in the HBO cops-and-robbers series "The Wire" and police use it to track every type of suspect — from terrorist to thieves stealing copper from air conditioners.

That investigators don't need a warrant to use GPS tracking devices in California troubles privacy advocates, technophiles, criminal defense attorneys and others.

The federal appeals court based in Washington D.C. said in August that investigators must obtain a warrant for GPS in tossing out the conviction and life sentence of Antoine Jones, a nightclub owner convicted of operating a cocaine distribution ring. That court concluded that the accumulation of four-weeks worth of data collected from a GPS on Jones' Jeep amounted to a government "search" that required a search warrant.

Judge Douglas Ginsburg said watching Jones' Jeep for an entire month rather than trailing him on one trip made all the difference between surveilling a suspect on public property and a search needing court approval.

"First, unlike one's movements during a single journey, the whole of one's movements over the course of a month is not actually exposed to the public because the likelihood anyone will observe all those movements is effectively nil," Ginsburg wrote. The state high courts of New York, Washington and Oregon have ruled similarly.

The Obama administration last month asked the D.C. federal appeals court to change its ruling, calling the decision "vague and unworkable" and arguing that investigators will lose access to a tool they now use "with great frequency."

After the D.C. appeals court decision, the 9th Circuit refused to revisit its opposite ruling.

The panel had concluded that agents could have gathered the same information by following Juan Pineda-Moreno, who was convicted of marijuana distribution after a GPSdevice alerted agents he was leaving a suspected "grow site."

"The only information the agents obtained from the tracking devices was a log of the locations where Pineda-Moreno's car traveled, information the agents could have obtained by following the car," Judge Diarmuid O'Scannlain wrote for the three-judge panel.

Two other federal appeals court have ruled similarly.

In his dissent, Chief Judge Kozinski noted that GPS technology is far different from tailing a suspect on a public road, which requires the active participation of investigators.

"The devices create a permanent electronic record that can be compared, contrasted and coordinated to deduce all manner of private information about individuals," Kozinksi wrote.

Legal scholars predict the U.S. Supreme Court will ultimately resolve the issue since so many courts disagree.

George Washington University law professor Orin Kerr said the issue boils down to public vs. private. As long as the GPS devices are attached to vehicles on public roads, Kerr believes the U.S. Supreme Court will decide no warrant is needed. To decide otherwise, he said, would ignore a long line of previous 4th Amendment decisions allowing for warrantless searches as long as they're conducted on public property.

"The historic line is that public surveillance is not covered by the 4th Amendment," Kerr said.

All of which makes Afifi's lawyer pessimistic that he has much of a chance to file a successful lawsuit challenging the FBI's actions. Afifi is represented by Zahra Billoo of the Council on American-Islamic Relations, the country's largest Islamic civil rights group.

Afifi declined comment after spending last week fielding myriad media inquiries after wired.com posted the story of his routine oil change and it went viral on the Internet.

Still, Billoo hopes the discovered GPS tracking device will help publicize in dramatic fashion the issue of racial profiling the lawyer says Arab-Americans routinely encounter.

She said Afifi was targeted because of his extensive ties to the Middle East, which include supporting two brothers who live in Egypt and making frequent overseas trips. His father was a well-known Islamic-American community leader who died last year in Egypt.

"Yasir hasn't done anything to warrant that kind of surveillance," Billoo said. "This was a blatant example of profiling."
