High-tech product releases: ultra-thin laptops, stealth robot vacuum, flicker free 3D TV

High-tech product releases announced the week ending February 23 include the world's first flicker-free 3D TV, thin laptops with all-day battery life, a waterproof and shockproof camera, a robot vacuum that's low on noise and a stylish Bluetooth headset.

World's first 'flicker-free' 3D TV
LG's Cinema 3D TV (LW5700) is the first TV to get the "flicker-free" certification from Europe's Intertek and TUV certification agencies. According to LG, the smooth picture technology found in its Cinema 3D TV "practically eliminates the feelings of dizziness or eye fatigue that could occur with previous 3D TVs." The TV is teamed up with inexpensive lightweight 3D glasses that have no electrical parts so they don't need to be synced with the TV or recharged. The Cinema 3D TV will be available globally from March. Pricing is yet to be confirmed.

High performance, all-day battery life in 'ultra-thin' laptops
There are six new laptops in Lenovo's newly announced ThinkPad laptop series: the T420s, T420, T520, L420, L520 and W520. Each laptop provides smart PC features, video and voice calling, and all-day battery life in a thin design. The T420 provides up to 30 hours of battery life with an extended battery while the T420s boasts a boot time that's 30 percent faster than previous models. The laptop series will be available from March. Pricing for the T420s, T420, T520, L420, L520 and W520 starts at approximately $1,329, $779, $909, $719, $719 and $1329, respectively.

A notebook with a 'smart battery' concept and thin design
Sony's new VAIO S Series is a slimmed-down notebook with a 13.3" display. The laptop sports a "full flat" design that has been crafted from magnesium and aluminium, measures 24mm thick and weighs 1.75kg for easy portability. The notebook will last up to seven hours in "stamina mode" and has a second battery that plugs in for up to 14 hours of battery life (sold separately). The Sony VAIO S series will be available in March for £899 (€1060).

A waterproof, dustproof and shockproof camera with GPS

The Pentax Optio WG-1 GPS is an extra-rugged camera perfect for photographers that like extreme sports. The camera is waterproof up to 10m, shockproof to withstand falls of 1.5m, crushproof to withstand up to 100kgf and coldproof to sub-freezing temperatures of 10 degrees C. Other features include GPS picture tagging, a 5x optical zoom lens, a 14 MP image sensor, video capture at 720p and Eye-Fi wireless SD memory card compatibility. The Optio WG-1 GPS will start shipping in April for $399.95.

An automatic robot vacuum cleaner that hardly makes a sound
The Samsung Electronics Tango Stealth Robot Vacuum Cleaner is designed to quietly make its way around your house sucking up dust and leaving your floors sparkling clean. The vacuum emits less than 50dB - an average conversation is around 60dB - but is powerful enough to suck up fine dirt. It has a detachable microfiber mop, an upgraded sensor, and settings for care, turbo and edge modes. Pricing and release dates are yet to be announced.

A stylish Bluetooth headset with new voice features
Jabra's Stone2 Bluetooth headset replicates the slick design of Jabra's first edition Stone headset while adding new hands-free voice-activated features. The headset alerts wearers of incoming calls by announcing who is calling and allowing the user to either "answer" or "ignore" with voice prompts; it also comes with dual microphone technology for better sounding calls. The headset comes with its own portable charger for anywhere power. The Jabra Stone2 is available for $129.99 now.
