No Galaxy Nexus in India: Samsung

NEW DELHI: For all those waiting for Samsung Galaxy Nexus in India, here's a bad news. The company has just announced via Twitter that India will not see the launch of Galaxy Nexus.

The announcement comes as a reply to a question posed by one Amit Wagh, who apparently asked why there was no Galaxy nexus in India?

Samsung's reply: "The Galaxy nexus will not be launched in India. Watch this space for the next big thing."

This is the first official denial from the company regarding the smartphone's launch in the country.

Galaxy Nexus is the first Android's Ice Cream Sandwich device officially announced in Hong Kong in October last year. Since then, the smartphone has been launched in several markets across the globe including US, UK, Singapore, Japan and Korea.

Galaxy Nexus comes with a 1.2GHz dual-core processor and has a 5-megapixel rear-facing camera and a 1.3-megapixel front-facing camera. It has a Super AMOLED Plus display measuring 4.65 inch, with a 1280-by-720-pixel resolution. The device also comes pre-installed with Google Wallet, which allows users to make purchases with the tap of a phone at some retail stores.

Incidentally, Google Inc recently announced that it will be selling the Android handset on its revamped "Play" service, which features Android applications, music, books and movies.

Isro's RISAT 1 satellite has Amdavadi heart

AHMEDABAD: There is a lot more of Ahmedabad in India's latest satellite orbiting the earth than originally thought. Space Application Centre (SAC) of Indian Space Research Organization (Isro) of course designs payloads for satellites, but this time a Gandhinagar-based company has built the very heart of RISAT-1, launched last month from Sriharikota.

India all set to develop reusable rockets: DRDO

New Delhi: After the successful launch of Agni-V Inter-Continental Ballistic Missile (ICBM), India is all set to develop reusable rockets which will combine the technologies of both ballistic and cruise missiles.
As part of plans to develop reusable ballistic missiles, Defence Research and Development Organisation will test indigenously developed scram jet engine next year, DRDO Chief VK Saraswat said in an interview to Doordarshan.
"We have propulsion technology, we have re-entry technologies, we have the technology which can take a re-entry system which will deliver a payload and have yet another re-entry system which will bring the missile back when it re-enters the atmosphere on its return journey," he said.
India all set to develop reusable rockets: DRDO
"We have demonstrated the performance of a scram jet engine operating at Mach six speed (six times the speed of sound)," he said.
On the range of Agni-V missile which was successfully test-fired recently off Odisha coast, the DRDO chief said with moderate modifications, "it can be extended to any range which is of our interest."
On technological capability available with the agency, he said, "DRDO has built the necessary technologies, production infrastructure and design capability for developing a booster or a sustainer... We have the capability to develop a re-entry nose cone which can withstand higher temperature and velocity."
Reacting to reports that India does not possess sufficient indigenous technology for missile guidance systems, Saraswat said Agni-V has used a completely indigenous and high precision missile guidance system with "0.001 degrees of per hour accuracy."
On criticism that DRDO sometimes does not live up to expectations, he said the agency was as good as its counterparts in advanced countries.
"Light Combat Aircraft (LCA), F-18 and Eurofighter took similar number of years and cost wise they were three times more than what we have put in our LCA," he said.
On development of Kaveri engine, Saraswat said it too has performed well and was, "flown an IL-76 aircraft in Russia, 55 hours of successful flight... We are going to upgrade it so that it can be used in India's LCA Mark-II and future systems."

Laser surgery gets ready to go internal

LaserScalpel2.jpg


Biomedical researchers have been excited about the surgical potential of laser pulses for years. But what they've been missing is a practical laser scalpel that can deliver the pulses - which last less than a trillionth of a second - inside the body.
Now Adela Ben-Yakar and colleagues at the University of Texas at Austin have developed a pulsing laser small and flexible enough to fit on the end of an endoscope like those used to examine the colon or stomach.
Short pulses are attractive for precision laser surgery because they concentrate their energy into a very small volume of tissue, so they remove a surface layer but leave lower layers or adjacent cells undamaged. The pulses have even been used to perform surgery on individual cells, primarily for research to study how cells operate.
It usually takes a big laser to produce a tiny pulse lasting only 200 femtoseconds, or 200 millionths of a billionth of a second - although the light pulse itself stretches only 60 micrometres. Earlier versions of the optical scalpel that is needed to focus the light precisely on the desired spot were about 18 millimetres in diameter, impractically large for insertion into body orifices.
Ben-Yakar's team designed a scalpel only 9.6 mm wide and 23 mm long that focuses light onto a spot 20 per cent smaller than before.  "All the optics we tested can go into a real endoscope," says Ben-Yakar. "The probe has proven that it's functional and feasible and can be [manufactured] commercially." Team member Christopher Hoy will describe it next week at the Conference on Lasers and Electro-Optics (CLEO) in San Jose, California.
Tabletop femtosecond lasers now perform surgery on the surface of the eye, but Ben-Yakar says the endoscope-mounted laser scalpel could be used inside the body to remove small tumours or repair damaged vocal cords. She also is exploring other possibilities for what she calls "next-generation clinical tools for microsurgery". Although the new design is ready for manufacture, it will require at least five years of clinical tests before it can be certified for human use by the US Food and Drug Administration.

HTC Rezound

The good: The HTC Rezound has a gorgeous 4.3-inch 720p HD display, a 1.5GHz dual-core processor, an 8-megapixel rear camera with dual-LED flash, a 2-megapixel front-facing camera, and Verizon's 4G/LTE speeds. It ships with a pair of Beats earbuds along with a Beats Audio algorithm designed to enhance audio quality.
The bad: The HTC Rezound is quite bulky and call quality could be better. The Beats Audio software can only be toggled in the Music app.
The bottom line: While it may have a hefty build, the HTC Rezound's beautiful display, commendable performance, and multimedia-rich features make it a top phone for Verizon customers.

The HTC Rezound is one of three hot new Android handsets headed to Verizon this holiday season--the other two are the superskinny Motorola Droid Razr and the Google-approved Samsung Galaxy Nexus. It's an embarrassment of riches for Verizon customers: they're all top-of-the-line phones with dual-core processors, support for Verizon's 4G LTE network, and features galore.
What sets the Rezound apart from its brethren, however, is that it is the first U.S.-bound handset with Beats Audio Technology, which HTC developed after it bought a majority stake in Dr. Dre's Beats Electronics. The phone ships with a pair of Beats Audio earbuds that are supposedly worth around $100 on their own. When they are plugged into the Rezound, the phone will instantly recognize them as Beats earbuds and the user will then be able to boost the sound via a special Beats Audio algorithm.
The Rezound is a rather hefty phone, but it's also blessed with an amazing 720p HD display that showcases HTC's attractive Sense 3.5 user interface. It sits atop the Android 2.3.4 Gingerbread OS, but HTC has promised that Ice Cream Sandwich will be available for the Rezound "early next year." It also boasts an impressive 8-megapixel camera with an f/2.2 sensor, a 1.5GHz Qualcomm Snapdragon dual-core processor, 1080p HD video capture, a 2-megapixel front-facing camera, and of course support for Verizon's 4G LTE network.
Design
Out of all the 4G LTE handsets we've handled, the Rezound is probably the bulkiest. At 5.08 inches tall by 2.58 inches wide by 0.54 inch thick, the Rezound is undeniably beefy, and at 5.78 ounces, it's not that light either. The flip side to such heft is that it feels fairly solid in the hand. Clad in a matte soft-touch material similar to the coating on the Incredible and the Incredible 2, the Rezound has rounded corners and a topographic back cover that adds character to an otherwise simple slab. There's a wide island of ridges on the back to help with grip. The narrow bezel and tapered edges helped our small hands hold the phone without much discomfort.


The HTC Rezound has a gorgeous 4.3-inch Super LCD display with 720p HD resolution.
Similarly to the first Droid Incredible, the insides of the phone are red, which complements the phone's red and black coloring. Sure, no one will notice it unless the cover is taken off, but we appreciate HTC's attempt at making the phone beautiful inside and out. HTC carries the touch of red to other parts of the phone, like the ring around the camera lens, the speaker grille, the touch sensor lights, and the wired cord of the Beats earbuds. Perhaps not coincidentally, the Beats logo has the same color scheme as well, and is prominently placed on the battery cover.
All eyes will likely focus on the Rezound's stunning 4.3-inch Super LCD display instead, however. The display boasts 1,280x720-pixel resolution, which places it at 720p HD quality. Frankly, it's simply gorgeous. Images and text are buttery-smooth, with amazing clarity and vivid colors to boot. The colors look almost painted on. Video looks luscious on such a generous screen size, and browsing the Web is a treat.
The capacitive touch screen felt very responsive, thanks to the Rezound's 1.5GHz Qualcomm Snapdragon dual-core processor. There's a slight lag when scrolling through the browser, but on the whole, we were pleased with the snappiness we experienced when swiping and tapping. It offers pinch-to-zoom as well as a built-in accelerometer, light sensor, and proximity sensor. The LCD display does wash out slightly under the bright sunlight.
Like the HTC Rhyme, the HTC Rezound runs HTC Sense 3.5. This includes a new lock screen that provides instant access to four of your favorite apps--simply slide the appropriate shortcut over the metal ring and it'll launch immediately. Other welcome improvements include a three-dimensional home screen carousel, refined widgets, and the ability to add and remove home screen panels--you can have up to seven home screens overall. The main menu is divided into all apps, frequently used apps, downloaded apps, and Verizon apps.
Beneath the display are the usual four touch-sensitive controls for the home, menu, back, and search functions. On the right spine is the volume rocker, while the Micro-USB charging port is on the left. The Micro-USB port doubles as an MHL (Mobile High-definition Link) port that you can hook up to an HDMI adapter. The 3.5mm headset jack sits on top. The front-facing 2-megapixel camera is located on the upper-right corner of the display and the rear 8-megapixel sits on the back along with the LED flash.
Beats Audio experience
The Monster Beats brand has found its way into this phone in two ways. First, there's the included pair of Monster Beats in-ear headphones. These headphones come with all the expected Beats branding, red cable, and multiple ear fittings, as well as on-cable track control buttons and a microphone for taking calls. They sound great, though we wouldn't confuse their flimsy design with Monster's more durable $149 Dr. Dre Tour in-ear headphones.

The HTC Rezound ships with Beats Audio earbuds along with special software that helps boost the audio.
The second part of HTC's Beats infusion is a software button that toggles a sound enhancement effect on and off. The enhancement boosts the audio's volume, the bass is deepened, and the audio simply sounds rounder and fuller. This button is accessible from the notifications pull-down while you're playing music in the stock Music app, but, oddly, the button isn't available in other multimedia apps, including Google's own Music app (a separate but worthwhile download). Still, the Beats enhancements seem to carry over sonically to any running multimedia app, but only the stock Music player will afford you the displeasure of hearing the enhancement disengaged.
If you're buying this phone strictly on the basis of its superior sound quality, you may want to reconsider. Any comparable smartphone will be able to step up to this same sound quality with an investment in some high-grade headphones, which you'll probably end up buying anyhow, since the included headphones use a cable design that seems designed to fail.
Features
The HTC Rezound ships with Android 2.3.5 Gingerbread, which brings plenty of user interface improvements to Android 2.2 Froyo before it. As with all Android phones, the Rezound has support for Google's array of apps and services, many of which are preinstalled on the phone. They include Gmail, Google Talk, Google Search with Voice, Google Maps with Navigation, Google Books, Places, Latitude, and YouTube. Essential smartphone tools are also present, such as the usual phone and PIM tools like a calendar, an alarm clock, a calculator, a task manager, a to-do list, voice command support, and a speakerphone.
In addition to the Rezound's support for 4G LTE (which we'll get to in the Performance section), the phone has other connectivity features like Bluetooth 3.0, GPS, and Wi-Fi. You can use the Rezound as a mobile hot spot for up to 10 Wi-Fi enabled devices, but bear in mind that the mobile hot-spot option costs around $20 extra per month. As we mentioned earlier, you can use an MHL-to-HDMI adapter to hook the phone up to an HD television. The Rezound also supports 5.1 surround sound and SRS Wow HD surround when hooked up to your home theater. You can also send your media wirelessly to a DLNA-compatible television.
HTC and Verizon have packed the Rezound with plenty of preinstalled apps, which some might characterize as bloatware. They include Amazon.com's Kindle app, Blockbuster, Facebook, Footprints, Friend Stream, Hot Pursuit, Let's Golf 2, Polaris Office, Scan (a QR code scanner), Slacker radio, Video Surf, NFL Mobile, My Verizon Mobile, Mobile IM, V Cast Music, V Cast Videos, and VZ Navigator. There's also Visual Voicemail, which costs $2.99 a month. Unfortunately there's no option to uninstall these apps.
Like other HTC smartphones, the Rezound ships with HTC Watch, HTC's video download and rental service. You can rent or purchase TV shows and movies. Rental prices range from $2.99 to $3.99, while purchase prices range from around $8.99 to $14.99 for movies. We weren't able to check TV show prices with our review unit.
The HTC Rezound ships with the standard Android music player, which isn't a bad thing. The music is sorted via artist, album, and genre, and you can create and edit your own playlists. The phone comes with 16GB of onboard memory along with a 16GB preinstalled microSD card for you to store your music on. It supports up to 32GB cards if you want even more space.
Another notable feature of the Rezound is its 8-megapixel camera. It inherits the camera of the T-Mobile MyTouch 4G Slide, with its f/2.2 and 28mm wide-angle lens with a BSI (backside-illuminated) sensor. The BSI sensor is there to improve the camera's performance in low-light conditions, and purports to improve the image's dynamic range. There's also a dual-LED flash for the darkest conditions. The camera has tons of features like automatic face detection, panorama mode, and burst shot. You can read our review of the T-Mobile MyTouch 4G Slide for more on the camera's features.

The HTC Rezound takes good pictures overall, but low-light photos were a touch dimmer than we would like.
Picture quality on the whole was very good. Images of the great outdoors were crisp and bright, with vibrant colors. Low-light photos were sharp enough, but they seemed a little dimmer than we would like. Shutter speed was a bit inconsistent--at times we would get no shutter lag, while there were times when it would hesitate a little before snapping a photo. The camera can also record 1080p HD video. We weren't able to give the camcorder a full spin, but the short video clips that we captured looked good--we noticed very little blur or pixelation.
Performance
We tested the HTC Rezound in San Francisco using Verizon Wireless. Call quality was average. On our end, callers sounded decent enough, with good volume and clear voice quality. We did detect the occasional static hiccup in the background, but it was not distracting.
Callers could hear us loud and clear as well, but they said our voice quality was heavily distorted, and did not sound natural at all. They also heard odd audio fluctuations in the background at times. In speakerphone mode, callers said we sounded distant and soft, and we had to speak up more often than not.
HTC Rezound call quality sample Listen now:

We were very impressed with the data speeds exhibited on the HTC Rezound. Using Ookla's Speedtest.net app, we averaged download speeds of around 18Mbps and upload speeds of around 9Mbps. We loaded CNET's mobile page in 6 seconds and the full CNET home page in 14 seconds. We streamed YouTube videos in high quality with almost no buffering. The 1.5GHz dual-core processor resulted in zippy navigation, and we launched most apps without lag. The accelerometer took barely a second to kick in, and multitasking felt seamless.
The HTC Rezound has a 1,620mAH battery. We'll have to run more tests to judge its actual talk time. Anecdotally, however, the battery seems to drain fairly quickly after a solid few hours of playing music, surfing the Web, and streaming video.
According to the FCC, the HTC Rezound has a digital SAR of 0.427 watt per kilogra

Review: At Rs 6,499 Micromax Funbook tablet packs in enough bang for the buck


New Delhi: One thing is for sure, tablets are the future of education. But I am not quite certain if that tomorrow will be displayed on a 7-inch screen. 10-inch devices do seem to have an advantage. Even if they currently carry a heavier price tag, I am quite sure things will change fast. As fast as the plummeting prices of feature-rich tablet devices.
On Tuesday, when Micromax announced its awaited entry into the tablet market with the Rs 6,499 Funbook tablet (model number: P300) targeted towards the youth, the excitement and interest in the online world made it seem to be worth the wait. Two of the top 10 trends on Twitter that day was related to the tablet. I too couldn't wait to get my hands on the device and here is the first review that you will find anywhere of the Micromax Funbook tablet.
We should never be fooled by publicity images. All models, whether human or not look, attractive when properly photoshopped. Therefore I was a bit skeptical before I actually held the Micromax Funbook in my hand. The first thing that struck me was its weight, or rather the lack of it and also its comparatively slim profile.
Micromax Funbook: Rs 6,499 Android ICS tablet
Many of the much-hyped tablets, be it the world's cheapest Aakas tablet or the overpriced Milagrow TabTop PC, put me off at the first sight. I wouldn't want to be seen in respectable company with one of those fugly devices in my hands. The Micromax Funbook may not be the most handsome kid on the block, but it does have attractive looks. Available in two variants Slate Grey and Midnight Black, the review unit is Slate Grey. But I personally prefer Midnight Black.
There is also the recently launched HCL ME U1 tablet with comparable specs, but a Rs 1,500 higher price tag. Since I'm yet take the ME U1 for a test ride, I'll not proceed with further comparisons.
Measuring 12.2 x 19.2 centimetres the Micromax Funbook tablet is comfortable to hold with one hand for long durations, (aided by its minimal weight) unlike the Amazon Kindle Fire, which cannot be recommended for people with weak wrists.
Something that stands out like pimples on a teenager's face are the protruding home, menu and back buttons. Android Ice Cream Sandwich doesn't need these front hardware buttons and this makes me suspect that Micromax's device was not originally intended run on Android 4.0 and the software upgrade was thought of later taking note of the interest in the latest version of Google's mobile operating system. Sometimes it is a bit awkward to find two sets of buttons, one on the screen and other on the body to perform exactly the same functions. But the advantage of having the hard buttons is that they are easier to access than their tiny on-screen counterparts. But Micromax should have given adding touch buttons a thought. The tablet would've looked a lot sexier.
Android 4.0 (the Funbook runs version 4.0.3) is said to be a vast improvement over its predecessors and it is. When Android 4 is here, there's no point to go for a device with an older version of the OS and then wait for the manufacturer to release an official upgrade.
(An observation: Ice Cream Sandwich looks much better on the more compact smartphone screens than on the larger tablet displays. )
The tablet also claims to be an entertainment hub. I threw in a number of different popular formats at it, including some 1080p and it played them all smoothly. The 1.22GHz Cortex A8 processor with Dual Mali GPU seemed to be doing the job well. The sound output (via the built in speaker) is nothing to be very satisfied about and it is (as usual) advisable to invest in a good pair of headphones.
The presence of a mini-HDMI port extends the tablet to some exciting, albeit un-tablet-like possibilities. Because of its ability to play formats that the HD TV at home couldn't, I plugged the Micromax Funbook to television set and watched a few clips on a larger screen. It can also double up as a handy home media player.
The Micromax Funbook's capacitive screen will not dazzle you with its 800x480 pixel resolution. Also the viewing angles aren't that good. While the device plays 1080p videos, the lower screen resolution means that you cannot enjoy them in their full HD glory, but the video clarity makes watching HD videos more worth the while than other lower resolution videos. The touch is also quite responsive.
The presence of a mini-USB port came as a shocker. Expecting micro-USB compatibility is almost the norm for most devices nowadays since it is compliant with the Universal Charging Solution initiative. Don't know why Micromax chose to sail against the tide on this little but important point. Also having a non-standard charging socket and charger seems strange. When major manufacturers are coming together to develop standards, Micromax is breaking them with what is otherwise a more than satisfactory product.
The tablet doesn't have a rear camera and comes with a front VGA camera, that is only good for video chatting. To desire for a rear camera is asking for a bit too much at this price, at least for now.
The 2800mAh battery gives, according to Micromax, a browsing time of about 5 hours. That's not too great an achievement and something that we will have to learn to live with given that it is light on our wallets. I had been using the device intermittently (on WiFi) for this review and it ran out of juice in a little more than 4 hours.
Positioned as an education tablet, the Funbook comes preloaded with education apps. But they failed to impress. I quit the Vriti app soon after, not because I left school years ago but because it looks so unimaginative and was sluggish even on my high speed home WiFi. I wonder how Vriti (and Micromax by extension) will engage the young and demanding audience they are intending to target?
Also I have this thing against bloatware. Since it does not take a Herculean effort to install apps of the user's choice, manufacturers can at most point users to places that they think will be of the user's interest and not clog the device that she purchases with potentially unwanted software. Micromax's own app store that comes preinstalled with the device pales in comparison with Google Play or even the Amazon App Store. Also I don't get the idea of treating video files as apps.
With the Amazon Kindle App, that doesn't come preinstalled, the Micromax Funbook turns itself into a handy e-reader. Only if it had the battery to support extended reading sessions.
With tethering on my Android smartphone I no longer have the need for a separate Internet USB dongle and nor do many others. This means that I have hardly have any need for the bundled Tata DoCoMo 3G dongle. So does that translate into an even lesser price tag? Have to post this question to Micromax.
Even in this age of globalisation, we do take a lot of pride in made in India products. More so when the market is flooded with made in China stuff. The Micromax Funbook proudly flaunts its made in India tag and is said to be the first 'swadeshi' tablet. Our review device was manufactured at Simmtronics Semiconductors Limited, Roorkee, Uttarakhand.
India is a market of sasta, sundar and tikau (cheap, beautiful and durable). Very few products managed to score well on all three parametres. The Micromax Funbook tablet may not be Aakash cheap, but it is wallet friendly. It may not be a beauty queen but is pleasing to the eyes. Durability is a factor of time and usage, this is one factor that, as the cliche goes, only time can tell. But definitely paisa wasool (worth the money).
Before you rush out to grab a 7-inch Funbook for yourself, note that Micromax is expected launch a 10-inch tablet soon.
