Some of its uses include the Android operating system is used on smart phones, netbooks, tablet computers, Google TV, and other devices. The main hardware platform for Android is the ARM architecture. There is support for x86 from the Android-x86 project and Google TV uses a special x86 version of Android. First came Android 1.0 released on 23rd September 2008.It had Camera support, but no way to change resolution, white balance, quality, etc. It had Google Contacts synchronization with the People app. Then came Android 1.1 on 9th Feb 2009.After that was Android 1.5 Cupcake released on 30th April 2009.It had Virtual keyboard. It was followed by Android 1.6 Donut which released on 15th September 2009. It enabled users to select multiple photos for deletion. Then came Android 2.x (Eclair) released on 26 October 2009.It had Motion Event class enhanced to track multi-touch events. Followed by Android 2.0.1 released on 3 December 2009.Android 2.0.1 is a minor platform release deployable to Android-powered handsets. Then came Android 2.1.It released on 12 January 2010.Then came Android 2.2 released on 20th May 2010.It had Integration of Chrome's V8 JavaScript engine into the Browser application, improved Microsoft Exchange support (security policies, auto-discovery, GAL look-up, calendar synchronization, remote wipe).Improved application launcher with shortcuts to Phone and Browser applications. Then came Android 2.3(Ginger Bread) released on 6th December 2010.It has updated user interface design for simplicity and speed, support for extra-large screen sizes and resolutions (WXGA and higher),internet calling: Native support for SIP VoIP telephony.We think android is upcoming in the market because it gives us a variety of applications, and is also very fast. In future according to our study it's going to be a very useful operating system.1. INTRODUCTIONWith the exception of brief update periods, Android has been available under a free and open source software license since October 21, 2008 until March 2011. Google published the entire source code (including network and telephony stacks) under an Apache License. Google also keeps the reviewed issues list publicly open for anyone to see and comment. Even though the software is open-source, device manufacturers cannot use Google's Android trademark unless Google certifies that the device complies with their Compatibility Definition Document (CDD). Devices must also meet this...

This essay is on Magneticly Levitated Trains.... It explains basicly how they work as well as how they have a future in transportation because they are very efficiant

880 words - 4 pages dropped by the US due to lack of government funding. However, it is a technology that is almost at the point of commercial use in Germany and Japan (the 2 major testing facilities) (4).There are 2 main types of levitation and propulsion which I will explain in this essay, (EMS) Electromagnetic Suspension and ( EDS) Electrodynamic Suspension. EMS is run extremely close to the track (about 10mm), this makes it slightly unstable. EDS however is run

Maglev Trains And The Technology Behind Them

5084 words - 20 pages . ---------------------------------------------------------------------- The principle of a Maglev (Magnetic Levitation) train is that it floats on a magnetic field and is propelled by a linear induction motor. They follow guidance tracks with magnets and have been seen to have great potential in the transport world. [IMAGE]An example of a maglev train from Simple Theory A maglev train will float about 10mm

Maglev allows for frictionless travel by use of electromagnetism, which allows for much higher speed than conventional trains . Maglev technology will be adopted by the U.S.A. once more trains are in use on our soil. The price is currently estimated to cost between $10 million

How could magnetically levitated trains relieve the problems of efficiency, safety, and ecology associated with the conventional trains and airplanes?

2588 words - 11 pages trains could enhance present challenges of traditional transport. First, the essay is going to discuss the problems that are caused by traditional transport, next, it will provide data regarding magnetic levitation technology brief overview, and, then, it is going to suggest several factors that contribute to the improvement of the challenges linked with the conventional transportation by focusing on efficiency, safety and ecological impact

It would work by “placing sheets of similar monopoles under the train and on the tracks. Propulsion would be done by angling the sheets, which would accelerate or decelerate the train” (Sandberg). If implemented, will be of great economic, environmental, and safety benefits (Powell and Gordon). A magnetic monopole train can reduce

Maglev trains can do many good things, and it all started centuries ago. History Magnetic levitation uses magnets with the same charge that repel each other to make one of the magnets float. This is the basic concept that John Mitchell came up with in 1750. He saw that the repulsive

Magnetic Bearings and Heat

Normally, rotors are supported by mechanical bearings; however, this form of support is not able to obtain high speeds. When looking at high performance flywheel energy storage systems, either permanent magnetic levitation, superconducting bearings, or AMBs are used. AMB are most often chosen because its controllability allows for the rotor to work in

Active Vs. Passive Magnetic Bearings Essay

1890 words - 8 pages Introduction A magnetic bearing is a type of bearing that holds up a load using magnetic levitation. Scientists first discovered the magnetic effects in magnetic minerals in 500B.C. In the late 20th century, scientists began developing ways where this magnetic effect could be implemented into a bearing, creating magnetic bearings. Today, magnetic bearings can be found in many applications where no physical contact is required or extreme
