Do cell phones cause brain cancer, dementia or have other side effects? Though there have been numerous studies on this, the verdict remains unclear. For, some studies reveal long-term side effects of cell phone usage others term them as mere hype. However, it is largely certain that cell phones do emit radiation. In fact, some analysts are now of the view that all cell phones should compulsorily display their radiation levels. Recently one of the US-based environmental group EWG recently published a list of phones with high levels of RF radiation. The list includes some of the most popular smartphone models from companies like Apple, LG, HTC, Motorola, Blackberry and Samsung.

The study is based on SAR or Specific Absorption Rate. SAR according to the Cellular Telecommunications Industry Association is “a way of measuring the quantity of radio frequency (RF) energy that is absorbed by the body, (SAR is used to measure exposure to fields between 100 kHz and 10 GHz), as per standards it requires that phones sold have a SAR level at or below 1.5 watts per kilogram (W/kg) taken over a volume of 1 gram of tissue.. Here’s a quick view of that EWG list of the phones with high radiation levels and there SAR levels, in this week of my blog episode :

If you are following my tweets for past 2 weeks, you could have expected me to blog on 3D TVs and those who guessed it right, here it is the ‘Next Revolution in TV Viewing’, you can always expect my blog to be the first row bloggers on upcoming technology and this week I will brief you on what is 3D TV and 3D HDTV’s coming in 2010 to your nearest store. So sit back to read this exclusive insight to 3D Experience u will find it in your home in the coming months 😉

The era of the ‘Third Dimension’, seems to have finally arrived, enthralling audiences and challenging manufacturers. The year 2010 will see 3D TVs, which have largely been concepts so far, go mainstream. In fact, the recently-held CES saw a rage for 3D technology, with everything from 3D projectors to 3D glasses to 3D camcorders lapped up by the audience.

To be honest 3D Television is not a new concept at all it employs some technique of 3D presentation, such as stereoscopic capture, multi-view capture, or 2D plus depth, and a 3D display – a special viewing device to project a television program into a realistic three-dimensional field.
Occasional 3D episodes became moderately popular in the late 1990s when several shows used the technique to attract viewers and increase ratings.

So how does a 3D TV work ?

To see 3D, each eye needs to see a slightly different image, just like in real life. So a 3D TV uses a lenticular lenses assembled on top of the LCD-panel, to project a different image in your left and right-eye. Using both images, your brain then creates the 3D experience. 3D principle has been around for over 150 years (photo) and 80 years (film). Because of recent developments, it is now possible to provide a high-quality 3D experience without the need to wear special glasses. Other developments in technology boost developments in 3D, such as; availability of content in digital format, HD technology all over the place, and signal processing performance. This all will enable bringing 3D to mass markets, and could have an impact that is comparable with transition black and white to colour. It is known that in some cases people have difficulties to perceive depth. Nevertheless, even viewers who are not able to see 3D from stereoscopic images can still perceive and enjoy 3D while moving within the multi-views of the 3D displays.

What’s important is the content needs to be 3D. For these tools will be available to create 3D content from existing 3D animation software, games (OpenGL or DirectX applications), and stereoscopic video (two cameras)

Here’s a look into some of the cool products that promise to bring the 3D experience right into your living room:

    Panasonic

Panasonic unveiled the world’s largest HD 3D Plasma display. Standing tall and slim at 150 inches in size, the 3D TV offers a 1080p HD 3D display. It was declared the winner in the ‘Best of CES’ category and also in ‘Best in Television’ category at CES.

The 3D TV from Panasonic comes with a pair of 3D shutter glasses with a battery life of 250 hours of viewing. The glasses automatically turn off in case they don’t detect signal from the emitters.

Panasonic 3D TV series include TC-P50VT20 (50 inch); TC-P50VT25 (50 inch); TC-P54VT25 (54 inch); TC-P58VT25 (58 inch); and TC-P65VT25 (65 inch).Panasonic also launched 3D Blu-ray player and a 3D camcorder as part of its home theater set. Panasonic TC-PVT25 series is set for a second quarter release.

    Sony

The year 2010 will see a host of 3D TV launches from Sony in its popular Bravia range, Sony Bravia LX900 series. Sony 3D TV offers features like built–in wi-fi, intelligent presence sensor and the Edge LED backlight.

Sony, which has teamed up with IMAX and Discovery, also plans to launch a dedicated 3D TV channel. Sony has taken the 3D experience to gaming arena as well and says that users can play 3D games on a PS3 console. Sony 3D TV sizes include XBR-60LX900 (60 inch), XBR-52LX900 (52 inch), XBR-46LX900 (46 inch), and XBR-40LX900 (40 inch).

    Toshiba

Toshiba seems to have taken a slightly different path with its 3D TV launch. The company announced Cell TV, a full-blown Internet TV, which also offers 3D content. When 3D content isn’t available, Toshiba’s new converter would convert any kind of 2D content- games, movies or sports – into real-time 3D.

The television offers video conferencing with built-in microphone and a video camera. Cell TV also offers users the capability to download streaming content from internet.

    Samsung

Samsung unveiled 3D-ready DLP HD Television series. The size of the HD TV is 55 inches, and claims up to 1080p of speed. What makes the Samsung 3D TV stand out is its thinness with other on the camp.

    LG

null

LG too showcased its 3D TV range, Infinia LED HDTV series. LG LE9500, the company’s flagship model in the 3D range, is available in 55 and 47 inch models. With a depth of just 0.92 inches, LG LE9500 can be ranked among the slimmest 3D TVs. The TV comes with integrated wi-fi system, and offers Skype and DivX technologies.

So all those 3D buffs get ready for really cool 3D experience right in your living room in the coming months. Have a great week 😉
