HTC EVO 4G LTE
HTC EVO 4G LTE runs Ice Cream Sandwich out of the box. So we think it should end up getting an Android 4.1 Jelly Bean update.
Acer Iconia Tab A500
Acer updated the Acer A500 with Android 4.0 Ice Cream Sandwich. RandomBlame, a senior member of XDA-Developers’ forum, is the brilliant mind who ported Jelly Bean to Acer Iconia Tab A500 and what’s even more impressive is that he also played a pivotal role in the development of the two functional ROMs for the Galaxy S3 and One X. Therefore I think Acer may just end up giving Iconia Tab A500 an official Android 4.1 Jelly Bean update.
Toshiba Excite 7.7
Toshiba Excite 7.7 runs Ice Cream Sandwich as its operating system. Therefore Toshiba Excite 7.7 may end up getting an Android 4.1 Jelly Bean update.

Lots of people are asking me when will gadgets such as Sony Xperia S, Sony Xperia P, Sony Tablet S, Sony Tablet P, HTC Sensation XE, HTC Sensation XL, Motorola Droid Bionic, Motorola Droid 4, Motorola Atrix 2, LG Optimus 2X and HTC EVO 3D get an Android 4.1 Jelly Bean update. We will have to wait for an answer as Handset makers HTC, Sony Mobile (formerly Sony Ericsson), and LG have not confirmed when Android 4.1 Jelly Bean update will be available for their respective smartphones. But do not get disappointed if you do not get an official Jelly Bean update as XDA-Developers is always there to help you.
We’re stilling waiting to hear from a whole host of Android device manufacturers. Make sure you bookmark this page, as we’ll be updating this article as and when we hear back from manufacturers regarding their plans for the Android 4.1 update. In the meantime, take a look at our hands on Android 4.1Jelly Bean review to see what the jelly Bean update will be bringing.
Being unveiled at Google I/O 2012, Android 4.1(Jelly Bean) brings along a whole host of features to build upon the work started by Android 4.0 Ice Cream Sandwich. Android 4.1 Jelly Bean will be available in a few weeks. Besides the brand new Nexus 7 tablet, the first devices to receive the latest Android update from Google will be the Galaxy Nexus, Nexus S, and the XOOM. Following Google’s mind boggling Keynote announcement at Google I/O today, the Android team posted the platform highlights, recapping all of Jelly Bean’s new features. Here are a few we are particularly excited about.
Android 4.1 Jelly Bean release date
OTA updates are scheduled to be pushed out mid-July, however this is initially to Motorola Xoom, Samsung Galaxy Nexus and Nexus S devices. Google has announced the Android Platform Development Kit, which means manufacturers and chipset vendors will be working with the search giant up to three months before each release of Android in the future – so waiting for each new iteration could be a thing of the past.
Faster, Smoother, More Responsive
Due to the success of Google’s “Project Butter”, the latest version of Android is just like the saying goes “as smooth as butter”. Jelly Bean is the most responsive and impressive version of Android to date coming with triple buffered graphics, extended vsync timing and intuitive touch that boosts your CPU at the next touch event to make sure lag is minimal.
Enhanced Accessibility
Jelly Bean includes new API’s for accessibility features such as services that let you handle gestures and manage accessibility focus with on-screen navigation buttons. These can be handled by accessibility gestures, accessories, or other input methods. Applications that use the standard View components inherit support for these new features automatically without the need for developers to alter their code.
Android 4.1 Jelly Bean camera
Another update in the new iteration of Android is to the camera app. Whilst Android 4.0 brought fast image capturing, 4.1 takes this further. Image capture is smoother, but it is in the photo review where the major changes lie. Pinching brings a photo strip of all taken photos, with the swipe to delete making it easier to quickly remove unwanted images. Don’t worry though, there is an undo button making its way to the interface as well, so even if you accidentally scrub out that picture of a cat you once saw, it’s not gone for good.
Support For International Users
Android 4.1 helps developers reach more users through support for bi-directional text. Apps can handle text editing in left to right or right to left scripts. Apps can also make sure of new included Arabic and Hebrew locales and fonts. If that isn’t enough, the platform now supports user-installable keymaps.
Expandable Notifications
Android 4.1 brings a major update to Android notifications. Apps can now display larger, richer notifications to users that can be expanded and collapsed with a pinch. Notifications support new types of content, including photos, have configurable priority, and can even include multiple actions assigned to them.
Resizable App Widgets
Android 4.1 introduces improved App Widget functionality that can automatically resize, based on where the user drops them on the home screen, depending on the size, and the amount home screen real estate available. You can also supply separate landscape and portrait layouts for your widgets, which the system activates depending on your current screen rotation.
High Resolution Contact Photos
With Android 4.1, we cab finally store our contact photos at a whopping 720 x 720, allowing contact pictures to be truly beautiful. Apps can store and retrieve contact photos at that size or use any other size as needed.
Android Beam
Android Beam was introduced with ICS, but we haven’t seen a lot of uses for it. In Android 4.1, Android Beam makes it easier to share images, videos, or other payloads by leveraging Bluetooth for the data transfer. When the user triggers a transfer, Android Beam hands over from NFC to Bluetooth, making it easier to transfer and manage files between devices.
Smart App Updates
The latest feature of Google Play introduces a better way to receive application updates on your devices. When a developer publishes an app update, Google Play now only delivers the changes bits of the application rather then the entire APK. This makes app updates much lighter and easier on your network data. On average, a smart app update is about 1/3 the size of the full APK update.
Google Voice Search and Google Now
Google has drastically improved the default Voice Search functionality with Android 4.1. Dubbed Google Now, the new search functionality makes search much more visual such as displaying your results as cards for weather, navigation routes, sports scores, and more. This is much more than a virtual assistant.
Better Battery Life
Using Touch Input Boost, Android 4.1 boosts the CPU so that loading times are faster, and therefore uses less battery power. Updates to Google Play also mean that now app updates are smarter. Rather than downloading and installing the whole installation file, apps only install changed elements, making them on average 66% smaller.
Linux is gaining ground in India. After Dell decided to launch Ubuntu-based PCs and Laptops in India, an Indian company named Niam Computech has decided to launch its own range of Ubuntu based laptops and desktops. Niam Computech Pvt Ltd started in 2010 as Kaspersky Antivirus distributor for entire North India (except Delhi NCR) retail market. Along with Kaspersky they also distributed Vipre, AVG antivirus products, Kensington peripherals & accessories, Dolgix Memory Modules in entire Upper North India till Q4 2011 (March 2012). In 2012 they are distributing VMC systems networking / telecom products in India & worldwide, and marketing their own PCs, Servers, Laptops & Tablets.
Niam Computech now currently sells laptops, desktops (AIOs), mini pcs, and servers powered by Ubuntu. Their future goal for next 5 years is to market Ubuntu and Linux based electronics products in India. They are in talks with Canonical to allow them to join its OEM program. They are looking forward to sell around 500 AIOs and 1000 Laptops by FY 2012. These developments are interesting considering the fact that Niam Computech is the first Indian company to launch Ubuntu based products.
The Indian government has been fairly helpful of the perspective behind Ubuntu. The Supreme Court of India is using the application in 20,000 personal computers. University of Delhi is already using the software in 10,000 personal computers and various Assam academic organizations are also using it. These facts show that the demand for Ubuntu based products is surely increasing in India and especially in the education sector. The open source trend is catching on in the IT and electronics space in India which gives Niam Computech a good platform to launch their Ubuntu based products.
1. Notebooks (14.0 and 15.6 inch running on Intel based i3/i5/i7 processors)
2. Ultrabooks (14.0 inch running on Intel based i3/i5/i7 processors)
3. AIOs (15.6, 17.3, 21.5 inch all in one PCs running on Intel based atom/i3/i5/i7 processors)
4. Tablets (7″ and 10.1″ running on android and ARM Cortex A8, A9 based chipsets)
What is Ubuntu?
Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customize and alter their software in whatever way they see fit. “Ubuntu” is an ancient African word, meaning “humanity to others”.
The Ubuntu distribution brings the spirit of Ubuntu to the software world. Ubuntu has an installable live CD, creative artwork, desktop themes and migration assistant for Windows user. Ubuntu has a feature that support the latest technologies such as 3D desktop effects, easy installation of device drivers for ATI and NVDIA graphics card and wireless networking and the on demand support for non-free media codecs.
Today, Microsoft announced the latest version of its popular productivity suite, Office 2013. The Office suite has been reworked with Windows 8 and touch-screen tablets in mind. One more key feature is that it will rely heavily on the cloud.
If you're eager to get your hands on this new set of tools, you'll be glad to know you won't have to wait. Microsoft has posted a Customer Preview of Office 2013 here. You'll need to be running Windows 7 or the Release Preview of Windows 8 in order to install it. You will notice the Customer Preview runs a preview of Office 365 Home Premium Preview. In the end, you're still able to use the newly announced features, but have to go through Office 365 to do so.
Nokia's Maemo and Intel's Moblin operating systems have been merged to create MeeGo. MeeGo is a Linux-based free mobile operating system project.Primarily targeted at mobile devices and information appliances in the consumer electronics market, MeeGo is designed to act as an operating system for hardware platforms such as netbooks, entry-level desktops, nettops, tablet computers, mobile computing and communications devices, in-vehicle infotainment devices, SmartTV / ConnectedTV, IPTV-boxes, smart phones, and other embedded systems. MeeGo is currently hosted by the Linux Foundation.
History
It was first announced at Mobile World Congress in February 2010 by Intel and Nokia in a joint press conference. The stated aim is to merge the efforts of Intel's Moblin and Nokia's Maemo former projects into one new common project. According to Intel, MeeGo was developed because Microsoft did not offer comprehensive Windows 7 support for the Atom processor.
Things u should know about MeeGo
ØMeeGo is a Linux-based software platform that has been created from Intel's Moblin platform and Nokia's Maemo platform.MeeGo isn't just a direct competitor for the likes of the iPhone, Android OS-powered devices, Windows Phone 7 Series, Palm's webOS and RIM's BlackBerry platform. It's aimed at a much broader range of applications. The Linux-based MeeGo platform is intended to power multiple types of devices including smartphones, netbooks, tablets, connected TVs, mobile computers and in-car entertainment systems.
ØMeeGo isn't going to replace Symbian as Nokia's smartphone platform of choice.Nokia's executive vice president of devices, Kai Oistamo, said at the MeeGo launch that the two operating systems would continue to co-exist.MeeGo will offer a range of rich online and computing experiences with rich graphics, multitasking and multimedia capabilities.
Nokia's Maemo platform was recently given an airing on the Nokia N900 smartphone.
ØThe MeeGo platform will be developed as an open source project hosted by the Linux Foundation.MeeGo should be attractive to application developers as it uses the Qt application development environment, which enables developers to write applications just once and easily deploy them across variety of platforms and devices.
ØMeeGo applications for Nokia devices will be sold through the Ovi Store for Nokia, while Intel's AppUp Center will handle applications for Intel-based MeeGo devices.
Core OS
The MeeGo Core operating system is a Linux distribution, drawing on Nokia’s Debian-based Maemo and Intel’s Fedora-based Moblin.MeeGo is one of the first Linux distributions to use the Btrfs file system as default, and uses RPM repositories.
Nokia N9 Smart Phone with MeeGo OS
Jolla develops and sells smartphones based on the MeeGo platform. It continues the work started by Nokia and produced the Nokia N9 but needed a new company after Nokia has decided to abandon MeeGo. The Jolla team was formed by directors and core professionals leaving Nokia's MeeGo N9 organisation, together with some of the best minds working on MeeGo in the communities. Jolla intends to announce its first smartphone product during 2012.

Ohm’s Law relates current to voltage in DC circuit in the
form of V = iR
Capacitive touch screen uses Alternating Current (AC).
The current is continuous across the ITO surface, remember Sinusoidal waves from lab.
Impedance is equivalent to resistor in AC circuit implies, V
= iZ; where Z = (1/JwC)
And, J = sqrt(-1) w= 2pF where F = Freq.
C = Capacitance = (erA)/d
Human body achieves capacitance and conducts current.
Touch Event implies, Voltage drop at the point of touching.
Thus affecting the strength of current, across the ITO
surface.
Also, Voltage gradient across surface.
Conductive ITO surface allows for continuous current across
the surface.
Electronic circuits located underneath ITO surface measure
the resulting distortion in the sine waves produced by voltage drop as a result
of the touch event.
III. SURFACE ACOUSTIC WAVE:
Based upon emission and absorption of sound waves
Materials used are:
Transducers
One glass screen
Reflectors
Sensors
Two transducers are placed along the X and Y axes and
generate sound waves.
The waves propagate across the glass and are reflected back
to the sensors.
When screen touched, a portion of the wave is reflected back
to the sensors immediately.
The sensor is able to tell if the wave has been disturbed by
a touch event at any instant, and can locate it accordingly.
How do the sensors tell?
Waves travel at the speed of sound, Speed of Sound = 343 m/s
Based on the time it takes for the wave to return to the
source, the sensor can tell if it was disturbed or not.
If it was, based on the time it takes to get back to the
source, the sensor can calculate the distance.
These calculations will generate (X,Y) coordinates
Benefits
100% clarity because of the lack of metallic layers in the
screen
Able to interact with the use of multiple mediums like
Stylus, finger, glove etc
Negatives
Screen can become contaminated and cease to operate
correctly.
IV. INFRARED:
An infrared touchscreen uses an array of X-Y infrared LED
and photodetector pairs around the edges of the screen to detect a disruption
in the pattern of LED beams. These LED beams cross each other in vertical and
horizontal patterns. This helps the sensors pick up the exact location of the
touch. A major benefit of such a system is that it can detect essentially any
input including a finger, gloved finger, stylus or pen. Unlike capacitive
touchscreens, infrared touchscreens do not require any patterning on the glass
which increases durability and optical clarity of the overall system. Infrared
touchscreens are sensitive to dirt/dust that can interfere with the IR beams,
and suffer from parallax in curved surfaces and accidental press when the user
hovers his/her finger over the screen while searching for the item to be
selected.
V. OPTICAL IMAGING:
This is a relatively modern development in touchscreen
technology, in which two or more image sensors are placed around the edges
(mostly the corners) of the screen. Infrared back lights are placed in the
camera's field of view on the other side of the screen. A touch shows up as a shadow
and each pair of cameras can then be pinpointed to locate the touch or even
measure the size of the touching object (see visual hull). This technology is
growing in popularity, due to its scalability, versatility, and affordability,
especially for larger units.
VI. DISPERSIVE SIGNAL TECHNOLOGY:
Introduced in 2002 by 3M,
this system uses sensors to detect the piezoelectricity in the glass that
occurs due to a touch. Complex algorithms then interpret this information and
provide the actual location of the touch. The technology claims to be
unaffected by dust and other outside elements, including scratches. Since there
is no need for additional elements on screen, it also claims to provide
excellent optical clarity. Also, since mechanical vibrations are used to detect
a touch event, any object can be used to generate these events, including
fingers and stylus. A downside is that after the initial touch the system
cannot detect a motionless finger.
VII. ACOUSTIC PULSE RECOGNITION:
In this system, introduced by Tyco International's Elo division in 2006, the key to the invention
is that a touch at each position on the glass generates a unique sound. Four
tiny transducers attached to the edges of the touchscreen glass pick up the
sound of the touch. The sound is then digitized by the controller and compared
to a list of prerecorded sounds for every position on the glass. The cursor
position is instantly updated to the touch location. APR is designed to ignore
extraneous and ambient sounds, since they do not match a stored sound profile.
APR differs from other attempts to recognize the position of touch with
transducers or microphones, in using a simple table lookup method rather than
requiring powerful and expensive signal processing hardware to attempt to calculate
the touch location without any references. The touchscreen itself is made of
ordinary glass, giving it good durability and optical clarity. It is usually
able to function with scratches and dust on the screen with good accuracy. The
technology is also well suited to displays that are physically larger. Similar
to the dispersive signal technology system, after the initial touch, a
motionless finger cannot be detected. However, for the same reason, the touch
recognition is not disrupted by any resting objects.
CURRENT USES:
Kiosks: ATMs, Self Checkout Counters, Airport Check-in, etc.
PDAs
Tablet PCs
Mobile
Phones or rather Smart-Phones
Handheld Gaming Consoles

Here's a video of a Surface acoustic Wave technology.
Well how good it would be when we could control any and everything
with just one touch but, halt your imagination that time is too far so, live in
present and the present is that touchscreens have just marked their successful
commercialized beginning. This article is to give you the slightest idea of how
a touchscreen works, more importantly to give a detailed idea of the various
touchscreens technologies. To start with let’s describe what a touchscreen
means for those who might be reading the term for the first time.
A touchscreen
is an electronic visual display that can detect the presence and location of a
touch within the display area. The term generally refers to touching the
display of the device with a finger or hand. Touchscreens can also sense other
passive objects, such as a stylus. Touchscreens are common in devices such as
game consoles, all-in-one computers, tablet computers, and smartphones.
The History of touchscreen is marked by various individual
scientists but not any organization in particular. E. A. Johnson was the first
person to have such a vision; he not only published articles on capacitive
touchscreens but also worked up ways to build them. Later Bent Stumpe of CERN
with the aid of Frank Beck developed the first and only one of its types, the
capacitive touch screen. This was the time 1982 when Computers and Mobilephones
itself were marking their existence. Thus, without making these devices a
complex by introducing the touchscreen technologies it was decided to keep
within. But, Hewlett Packard (HP) had something else in mind, the launched the
first touchscreen model of PC’s named HP-150 and commercialized it worldwide.
It was a great help at Kiosks, Banks, Ticket booths etc. Similar to the PLATO
IV system, the touch technology used employed infrared transmitters and
receivers mounted around the bezel of its 9" Sony Cathode Ray Tube (CRT),
which detected the position of any non-transparent object on the screen.
Parallel to it was the beginning of INTERNET which itself spread like virus but
also made the technologies acknowledged to the world market.
TECHNOLOGIES:
There are a variety of touchscreen technologies that have
different methods of sensing touch which are viz.-
Resistive
Touch
Surface
Acoustic Wave
Capacitive
Touch
Infrared
Optical
Imaging
Dispersive
Signal
Acoustic
Pulse Recognition, technologies.
We will now discuss about each but first with the widely
used ones.
I. RESISTIVE TOUCH:
It has two resistive (provides resistance) surfaces made out
of Indium-Tin Oxide. These are
metallically coated and have insulating spaces. On touching, compression takes
place as shown in the above image leading to formation of a closed circuit.
This is why gadgets with resistive touchscreens have to be pressed harder so
that the contact remains intact and as the movement passes through the
insulating spaces it analyses the direction of motion. It is most widely used
due to its simple structure.
It again has two types:
1. Matrix (digital):
Striped electrodes on substrates such as glass or plastic
face each other
2. Analogue:
Transparent electrodes without any patterning facing each
other
Low production costs
Overview of the
Position Management System:
There are two Parallel Sheets
If there is no pressure applied – Electronically separated
If applied pressure – Impedance
between the two sheets is lowered at the touch point.
Measurement of X
& Y Coordinates:
Top sheet carries a voltage
gradient by applying a voltage between the electrodes of top sheet
Bottom sheet serves as a slide in a linear potentiometer.
Voltage
Gradient:
Linear
Potentiometer:
Linear potentiometers are sensors that produce a resistance
output proportional to the displacement or position. Resistance value changes
with rotation of screw.
Conduction Current:
Electrons move along
Displacement Current:
Electrons are completely displaced
RESISTIVE TOUCH:
Measurement of the touch point resistance is valuable. Value
varies depending upon force applied.
