Nikon D4 Ethernet DSLR : The new inovation form Nikon

The new Nikon D4 offers slightly higher frame rates, slightly higher resolution, an updated AF system that works better with teleconverters, Kelvin white balance settings in 10K increments, a virtual horizon that finally works properly with both roll and pitch, much higher ISOs than the D3 and D3s, and wow, video.

The Nikon D4 is aimed at full-time professional news, sports and action photographers – or videographers shooting Canon DSLRs. The D4 is equipped with a new Nikon FX-format CMOS image sensor (imaging size of 36.0 x 23.9 mm) and EXPEED 3, the latest image-processing engine specifically optimized for digital-SLR cameras, making it the next-generation flagship Nikon digital-SLR camera with the ultimate in versatility and functionality that offers superior image quality rich in detail along with excellent high-speed performance. It has an effective pixel count of 16.2-million pixels, and offers superior image quality under a broad range of lighting conditions with its image sensor supporting an incredible range of sensitivities from ISO 50 to ISO 204800.

The biggest technical changes are the addition of a 91,000 pixel ‘metering’ sensor, replacing the 1005 pixel example used up until now. This sensor is used for much more than just metering, playing a key role in subject tracking, white balance and ‘Active D-lighting’ (a trick Canon seems impressed with, given the appearance of a similar system in the 1DX). The higher-resolution sensor allows the camera to offer face detection when shooting through the optical viewfinder.

Then there are the ergonomic changes to the camera’s body. Again like Canon’s 1DX, moves have been made to make the ergonomics of portrait-orientation shooting more closely resemble those of shooting in landscape format. The camera no longer features a dedicated AFL button, instead gaining push-button joysticks for both the vertical and landscape shooting orientations. An additional rubberized lump has also been added to provide a better grip in the vertical orientation and an additional function button added next to the vertical shutter button.

Key Specifications:

• 16.2 effective megapixel, full-frame sensor (16.6MP total)
• 10fps shooting with AF and AE, 11fps with focus and exposure locked, 24fps 2.5MP grabs
• 91,000 pixel sensor for metering, white balance, flash exposure, face detection and active d-lighting

• 1080p30 HD video at up to 24Mbps with uncompressed video output
• New EN-EL18 battery (21.6Wh capacity, CIPA-rated at 2600 shots)
• Twin card slots – one Compact Flash and one XQD
• Compact Wireless Transmitter WT-5
• Ethernet connection to PC or Laptop for web based data browsing

Bajaj Introduces KTM 200 Duke Motorbike at Rs 1.18 lakh

The country’s second-largest two-wheeler maker Bajaj Auto on Tuesday launched a sports bike, ‘Duke 200′, from Austrian partner KTM’s portfolio and said it plans to roll out three more products in as many years. Bajaj owns a 39.26% stake in Austria’s KTM. The 200 Duke, priced at 117,500 rupees ($2,340) at showrooms in New Delhi, will be sold through 32 exclusive showrooms in 30 cities in India. The KTM stores will also sell the Bajaj Pulsar 220 and 200 bikes, apart from the Kawasaki Ninja 250R and 650R.

he Duke 200 developed jointly by the two firms has been launched at an introductory price of Rs 1.18 lakh (ex-showroom Delhi). This is the first bike from their collaboration to be launched in India. Last year, a jointly developed 125-cc version of the Duke was launched in Europe.

The BAL Managing Director Rajiv Bajaj told that the company will launch at least one new KTM bike every year in India. we intend to further strengthen our position in the sports motorcycle segment in India Between Bajaj Pulsar and KTM Duke. KTM Sportsmotorcycle AG Chief Executive Officer Stefan Pierer said: “Next year, we will launch a 350-cc bike and it will be followed by two more bikes in the next three years.

BAL is already exporting India-assembled KTM bikes. It supplied around 11,000 units of the Duke 125 in 2011. “In a very short span of time, KTM will be the largest premium bike-maker in the world with entry into many mass markets like India and Malaysia. This year, we are expecting to double exports from India.

The specification of BAJAJ KTM Duke 200 is 200 cc oil cooled engine, 25 BHP power, 6 speed transmission, 0-60 at 3.3 sec acceleration.

Facebook finally overtakes Orkut in Brazil

Last year marked a turning point for Facebook’s popularity in Brazil, which has until now failed to surpass that of Google’s Orkut, the latest figures from comScore, the online measurement company, show.In December 2011, Facebook attracted 36.10 million visitors – representing an increase of 192 percent in the past twelve months, according to comScore. Orkut took second by attracting 34.42 million visitors (growing just 5 percent in the past year).

Windows Live Profile was in third with 13.30 million (up 13 percent), Twitter was fourth with 12.50 million (up 40 percent), and Vostu was fifth with 4.90 million (up 338 percent). New to the scene last year, Google+ attracted 4.3 million visitors during December 2011, taking sixth place ahead of Tumblr and LinkedIn. Facebook is not only growing when it comes to its Brazilian user base, but the country’s users are becoming more engaged. In December 2010, an average visitor spent 37 minutes on the site. In December 2011, that number had surged to 285 minutes (up 667 percent). Visitors consumed an average of 500 pages of content on the site during December 2011 (up 655 percent), and visited the site an average of 27 times during the month (up 163 percent).

The figures indicate rapid growth for Facebook, a 192% year-on-year rise in visitors. Comscore’s Alex Banks said Brazil had the fifth largest social networking population in the world. “Facebook’s rapid ascent in the Brazilian market has certainly been one of the most interesting stories to develop during the course of 2011,” said Alex Banks, comScore’s managing director for Brazil. “Brazil has always been a particularly social market and currently owns the fifth largest social networking population in the world. The shift in power between Facebook and Orkut, is significant as Google has always been able to boast of its social network success and dominance in Brazil. As Google tries to compete with Facebook in the form of Google+, it will be interesting to see how Orkut’s popularity adapts over the next 12 months.

Whats new after CRT, LCD, LED & Plasma!

Yes Technology have no boundary. We are upgraded with every new technology. The invention of the television was the result of the work by many inventors, scientists and engineers in the late 1800’s and early 1900’s.  Many inventors made technological breakthroughs that were used by other inventors to successfully make working television systems.  The first working television systems were electromechanical and used a motor-generator.  Electronic television systems or all-electronic television systems do not have or use a motor-generator. The first electromechanical television was proposed and patented by Paul Julius Gottlieb Nipkow in 1884. The first Cathode Ray Tube (CRT) was built by Karl Ferdinand Braun in 1897. John Logie Baird was the inventor who built the world’s first working television system in 1925. The world’s first successful color transmission by John Logie Baird in 1928. The first working liquid crystal display (LCD) was built by George H. Heilmeier in 1964. After the LCD it is the time of LED & Plasma age. But now LCD, LED & Plasma are old technologies. The Latest & new technology is OLED (organic light-emitting diode). which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current. This layer of organic semiconductor material is situated between two electrodes. Generally, at least one of these electrodes is transparent.

A typical OLED is composed of a layer of organic materials situated between two electrodes, the anode and cathode, all deposited on a substrate. The organic molecules are electrically conductive as a result of delocalization of pi electrons caused by conjugation over all or part of the molecule. These materials have conductivity levels ranging from insulators to conductors, and therefore are considered organic semiconductors. The highest occupied and lowest unoccupied molecular orbitals (HOMO and LUMO) of organic semiconductors are analogous to the valence and conduction bands of inorganic semiconductors. The most basic polymer OLEDs consisted of a single organic layer. During operation, a voltage is applied across the OLED such that the anode is positive with respect to the cathode. A current of electrons flows through the device from cathode to anode, as electrons are injected into the LUMO of the organic layer at the cathode and withdrawn from the HOMO at the anode. This latter process may also be described as the injection of electron holes into the HOMO. Electrostatic forces bring the electrons and the holes towards each other and they recombine forming an exciton, a bound state of the electron and hole. This happens closer to the emissive layer, because in organic semiconductors holes are generally more mobile than electrons. The decay of this excited state results in a relaxation of the energy levels of the electron, accompanied by emission of radiation whose frequency is in the visible region. The frequency of this radiation depends on the band gap of the material, in this case the difference in energy between the HOMO and LUMO.

As electrons and holes are fermions with half integer spin, an exciton may either be in a singlet state or a triplet state depending on how the spins of the electron and hole have been combined. Statistically three triplet excitons will be formed for each singlet exciton. Decay from triplet states (phosphorescence) is spin forbidden, increasing the timescale of the transition and limiting the internal efficiency of fluorescent devices. Phosphorescent organic light-emitting diodes make use of spin–orbit interactions to facilitate intersystem crossing between singlet and triplet states, thus obtaining emission from both singlet and triplet states and improving the internal efficiency.

Tablet war heats up in India between Indian Mobile Operators

India‘s communications giant Bharti Enterprises had launched a $220 tablet computer named Magiq for domestic market. Reliance Communication also launched a $286 Android tablet before a week ago. Beetel Magiq is an Android 2.2 tablet and incorporates all the high-end attractive features, state of the art designs, and customized applications to attract Indian customers, especially the youth.

Beetel Magiq sports 1 Ghz Snapdragon Processor with external memory support of up to 16 GB, front and rear facing 2 megapixel camera for video call, WVGA touch screen, 3G wireless and Wifi, HDMI Port, and a 3.5mm audio jack. It is priced 9,999 rupees.

Beetel is having the product manufactured in an undisclosed location abroad to take advantage of economies of scale. The product was designed by Beetel in tandem with Huawei Technologies. Reliance’s tablet, manufactured by Chinese copmany ZTE Telecom, is also a 3G tablet with 7-inch display running on Android 2.3 OS. With 512 MB RAM, it comes with a 4GB SD card and is extendable up to 32 GB.

The Android tablets from Reliance and Beetel will compete with netbooks at the low-end and the more expensive tablets like the iPad from Apple at the high end.

LML plans a comeback again in market with new models

Kanpur based Indian two wheeler company LML (Lohia Machinery Limited) palns to comeback again with the new & old successful models. The company will launch India’s first 200cc geared scooter against models such as Suzuki’s Access 125 and Mahindra 2 Wheelers’ Duro, Rodeo and Flyte.

The company has also launched the Select 4, four stroke scooter in the NCR region. The scooter will only be available in select regions of north India as has been the case with many of the past LML models. Coming back to the LML Freedom, the company will use the same old platform but will be a much evolved product and will be differently engineered. The bike will also get an all new engine range that will be frugal as well as powerful. The 100-125 cc segment of the market has seen a lot of action lately with big players like Hero Honda, Bajaj, Yamaha, Honda & TVS.

“We felt that Freedom still has an after-life simply because there is a section of satisfied consumers still using the motorcycle. We still have the old platform but the new Freedom will be a much-evolved product, which would be differently engineered with a new engine,” PS Choudhary, head of marketing and sales.

Choudhary said Freedom’s 100 cc variant would compete with Hero MotoCorp’s Passion Pro, while the 125 cc would be a sporty model. “LML has always been a niche player and has never been in the volume game, which will remain. Besides, within the next two months, LML will launch a 200 cc geared four-stroke scooter, the most powerful, geared scooter model in the country till date.
