Astronauts use robot arm for shuttle safety scan

Astronauts used a robot arm to scan the space shuttle Discovery's heat shield for damage on Wednesday as it headed for a Thursday rendezvous with the International Space Station.

"The mission is right on track ... We look forward to docking tomorrow," mission management chairman John Shannon told a press briefing at the Johnson Space Center in Houston.

The shuttle is due to dock with the ISS at 1233 GMT on Thursday to kick off a 10-day construction mission at the outpost that will feature five spacewalks.

Astronauts spent the morning remotely maneuvering the arm to slowly inspect the shuttle wings and nose in a now mandatory post-launch routine begun after space shuttle Columbia broke apart on its return to Earth in 2003.

The scan with lasers and digital cameras looked for any damage to the heat shield that might have occurred when Discovery hurtled into space from Florida on Tuesday.

Data collected is beamed back to Earth for study by NASA engineers who will scrutinize it over the next few days. Preliminary analysis revealed nothing amiss.

Three suspect panels were given an especially close examination. Engineers using a new X-ray analysis technique warned managers ahead of the launch that three of the wing's 44 carbon-composite panels had tiny cracks in their silicon-carbide coatings.

After a lengthy debate, managers opted to proceed with the launch and assigned teams to monitor the situation.Columbia was doomed by a hole in its wing heat shield from a blow by fuel tank insulation foam that broke loose during takeoff. The damage was not detected and the shuttle was destroyed by the high heat of re-entry into the atmosphere, killing the seven astronauts on board.

Loose tank foam has been a recurring problem on shuttle flights. NASA says the danger cannot be eliminated, but it has taken many steps to reduce it.

Video of Tuesday's liftoff showed several pieces of insulation flying off the tank late in the ascent when debris strikes pose less danger because they occur with less force.

The shuttle is carrying the 24-foot-long Harmony, an Italian-built unit that will be installed on the station and to which Europe's Columbus and Japan's Kibo modules will be attached on space missions starting in December.

The seven-member shuttle crew is led by retired U.S. Air Force Col. Pam Melroy. They will link up with a space station crew led by NASA astronaut Peggy Whitson.

Robots to Help Elderly

Can we think that robot is doing all the odd job of human .Robot is becoming as a right worker of many things.
If you grow old , expect to be served food by a robot, ride a voice-recognition wheelchair or even possibly hire a nurse in a robotic suit — all examples of cutting-edge technology to care for the country's rapidly graying population.

With nearly 22 percent of Japan's population already aged 65 or older, businesses here have been rolling out everything from easy-entry cars to remote-controlled beds, fueling a care-technology market worth some $1.08 billion in 2006, according to industry figures.

At a home care and rehabilitation convention in Tokyo this week, buyers crowded round a demonstration of Secom Co.'s My Spoon feeding robot, which helps elderly or disabled people eat with a spoon- and fork-fitted swiveling arm.

Operating a joystick with his chin, developer Shigehisa Kobayashi maneuvered the arm toward a block of silken tofu, deftly getting the fork to break off a bite-sized piece. The arm then returned to a preprogrammed position in front of the mouth, allowing Kobayashi to bite and swallow.

"It's all about empowering people to help themselves," Kobayashi said. The Tokyo-based company has already sold 300 of the robots, which come with a price tag of $3,500.

"We want to give the elderly control over their own lives," he said.

The rapidly aging population here has spurred a spate of concerns: a labor shortage, tax shortfalls, financial difficulties in paying the health bills and pensions of large numbers of elderly.

Moreover, a breakdown of family ties in recent years means a growing number of older Japanese are spending their golden years away from the care traditionally provided by children and grandchildren.

That's where cutting-edge technology steps in.

A rubber and nylon "muscle suit" developed by the Tokyo University of Science helps keep the elderly active by providing support for the upper body, arms and shoulders.

Powered by air pressure actuators, the prototype suit — which looks like an oversized life jacket — provides subtle backing to help older people lift heavy objects.

The intelligent wheelchair TAO Aicle from Fujitsu Ltd. and Aisin Seiki Co. uses a positioning system to automatically travel to a preset destination, and uses sensors to detect and stop at red lights, and to avoid obstacles.

Another wheelchair designed by the National Institute of Advanced Industrial Science and Technology responds to oral commands like "forward" and "back," "right" and "left."

Then there are cars designed for easy entry for the wheelchair-bound or those with difficulty walking, like Toyota Motor Corp.'s Welcab series. Its slogan: "A car that's more patient than your daughter."

Tired? Retire to a Lowland futon bed by Kaneshiro Tsuhso Inc. that can be adjusted into a reclining seat.

And there's help for caregivers, too.

A full-body robotic suit developed by the Kanagawa Institute of Technology outside Tokyo is a massive contraption powered by 22 air pumps to help nurses hoist patients on and off their beds.

Sensors attached to the user's skin detects when muscles are trying to lift something heavy — and signals to the air pumps to kick in to provide support.

Though the suit makes its wearer look a little like Robocop, a student who was easily lifted off a table in a demonstration said he felt comfortable during the test.

"It doesn't feel at all like I'm being lifted by a robot," he said. "This feels so comfortable and very human."

Recall your email

24hoursnews :IBM has released the latest versions of its enterprise collaboration software, Lotus Notes 8 and Lotus Domino 8. Lotus Notes 8 brings together e-mail, calendar, instant messaging, office productivity tools and custom applications.

It includes productivity tools enabling users to create open standards-based versions of spreadsheets, word processing documents and presentations, in addition to supporting many file formats from traditional stand-alone applications. It also supports multiple platforms, including Linux and Windows for clients and Windows, Linux, Sun Solaris, AIX and IBM System i for servers

How often you've wished you could recall an email which you regret having sent, or which could embarrass you.

Fret not, help is here. IBM's latest offerings in the collaboration platform, Lotus Notes 8 and Domino 8 come with a recall feature that allows you to call back an email that has been sent. Developed over the last 2 years, version 8 is based on the feedback of 25,000 businesses around the world.

According to the company, this release is one of the best in terms of collaboration features. It also has significant inputs from IBM's India labs. More importantly, this version can be accessed on the Blackberry platform too. The software will offer features like email, collaboration, calendar, instant messaging and other office productivity tools and custom applications.

It is for the first time that a software is based on the open-source eclipse platform, a departure from the fact that otherwise IBM has in the past used its proprietary technology.

Sandesh Bhat, director (design and technology innovation), IBM, said: "The whole idea behind this was to offer users the best in the Web2.0 capabilities. This is also our endeavour to develop the desktop of the future.

Lotus Notes 8 is much more than an email service, unlike competitive offerings. Lotus Notes 8 integrates work by building in instant messaging and presence awareness, office tools to create and edit documents, presentations and spreadsheets and infusing a business' custom applications, including help desk, CRM, sales force, discussion forums, blogs and more.

This is all possible as Lotus Notes 8 is built on the programming model of Lotus Expeditor 6.1.1, which is based on eclipse.org open standards. Lotus Expeditor 6.1.1 enables the construction and deployment of enterprise mash-ups, also known as composite applications. Lotus Notes 8 and Domino 8 support a variety of platforms, including Linux and Windows for clients and Windows, Linux, Sun Solaris, AIX and IBM System for servers.

The office collaboration market is estimated to be in millions. Frost and Sullivan in one of its reports mentioned that IBM with a 44.5 per cent market share is a market leader in India.
