Smart cities to get their own OS

Cities could soon be looking after their citizens all by themselves thanks to an operating system designed for the metropolis.

The Urban OS works just like a PC operating system but keeps buildings, traffic and services running smoothly.

The software takes in data from sensors dotted around the city to keep an eye on what is happening.

In the event of a fire the Urban OS might manage traffic lights so fire trucks can reach the blaze swiftly.

The idea is for the Urban OS to gather data from sensors buried in buildings and many other places to keep an eye on what is happening in an urban area.

The sensors monitor everything from large scale events such as traffic flows across the entire city down to more local phenomena such as temperature sensors inside individual rooms.

The OS completely bypasses humans to manage communication between sensors and devices such as traffic lights, air conditioning or water pumps that influence the quality of city life.

Channelling all the data coming from these sensors and services into a over-arching control system had lots of benefits, said Steve Lewis, head of Living PlanIT- the Portuguese company behind Urban OS.

Urban OS should mean buildings get managed better and gathering the data from lots of sources gives a broader view of key city services such as traffic flows, energy use and water levels.

"If you were using an anatomy analogy, the city has a network like the nervous system, talking to a whole bunch of sensors gathering the data and causing actions," said Mr Lewis.

"We distribute that nervous system into the parts of the body - the buildings, the streets and other things.

Having one platform managing the entire urban landscape of a city means significant cost savings, implementation consistency, quality and manageability, he added.

"And it's got local computing capacity to allow a building or an automotive platform to interact with people where they are, managing the energy, water, waste, transportation, logistics and human interaction in those areas."

That's dealt with by the building itself, with the devices very locally talking to each other to figure out what's the best solution for the current dilemma"

Urban apps

The underlying technology for the Urban OS has been developed by McLaren Electronic Systems - the same company that creates sensors for Formula One cars. The Urban OS was unveiled at the Machine-2-Machine conference in Rotterdam.

To support the myriad of different devices in a city the firm has developed an extensive set of application services that will run Urban OS, dubbed PlaceApps - the urban environment equivalent of apps on a smartphone.

Independent developers will also be able to build their own apps to get at data and provide certain services around a city.

Mr Lewis said that eventually applications on smartphones could hook into the Urban OS to remotely control household appliances and energy systems, or safety equipment to monitor the wellbeing of elderly people.

It could also prove useful in the event of a fire in a building, he said.

Sensors would spot the fire and then the building would use its intelligence to direct people inside to a safe stairwell, perhaps by making lights flicker or alarms get louder in the direction of the exit.

"That's dealt with by the building itself, with the devices very locally talking to each other to figure out what's the best solution for the current dilemma, and then providing directions and orchestrating themselves," said Mr Lewis.

'Magical actions'

Living PlanIT is working with Cisco and Deutsche Telekom on different parts of the system.

Markus Breitbach of the Machine to Machine Competence Center at Deutsche Telekom said that his firm was helping to bring all the parts of the Urban OS together.

"Everybody's talking about 50 billion connected devices, which effectively means huge amounts of data being collected, but nobody is really caring about managing it and bringing it into a context - and Urban OS can do just that," he said.

"If there's a fire alarm on the fifth floor and the elevator is going to the next floor, the light will switch on - but in addition the traffic lights will be switched accordingly to turn the traffic in the right direction so that fire workers can get through.

"And this is what Urban OS is providing, this kind of solution to analyse mass data, enter it in a context and perform magical actions."

A test bed for the Urban OS is currently being built in Portugal. For its work in developing smart cities, Living PlanIT was selected as one of the World Economic Forum's Technology Pioneers of 2012.

Plastic 'flying carpet' takes off

The sheet is lifted by the air packets, and propelled forwards

<!-- END - caption -->
<!-- end of the embedded player component --> <!-- Player embedded -->

A miniature magic carpet made of plastic has taken flight in a laboratory at Princeton University.

The 10cm (4in) sheet of smart transparency is driven by "ripple power"; waves of electrical current driving thin pockets of air from front to rear underneath.

The prototype, described in Applied Physics Letters, moves at speeds of about a centimetre per second.

Improvements to the design could raise that to as much as a metre per second.

The device's creator, graduate student Noah Jafferis, says he was inspired by a mathematical paper he read shortly after starting his PhD studies at Princeton.

He abandoned what would have been a fashionable project printing electronic circuits with nano-inks for one that seemed to have more in common with 1001 Nights than 21st-Century engineering.

Prof James Sturm, who leads Mr Jafferis' research group, conceded that at times the project seemed foolhardy.

"What was difficult was controlling the precise behaviour of the sheet as it deformed at high frequencies," he told the BBC.

"Without the ability to predict the exact way it would flex, we couldn't feed in the right electrical currents to get the propulsion to work properly."

What followed was a two year digression attaching sensors to every part of the material so as to fine-tune its performance through a series of complex feedbacks.

But once that was mastered, the waveform of the undulating matched that prescribed by the theory, and the wafting motions gave life to the tiny carpet.

In the paper describing the design, Mr Jafferis and his co-authors are careful to keep the word "flying" in inverted commas, because the resulting machine has more in common with a hovercraft than an aeroplane.

"It has to keep close to the ground," Mr Jafferis explained to the BBC's Science in Action, "because the air is then trapped between the sheet and the ground. As the waves move along the sheet it basically pumps the air out the back." That is the source of the thrust.

Ray hope

Harvard University's Lakshminarayanan Mahadevan, who wrote the 2007 paper in Physical Review Letters that inspired the whole project, expressed a mixture of surprise and delight at the Princeton team's success.

"Noah has gone beyond our simple theory and actually built a device that works," he told the BBC "And what's more, it behaves, at least qualitatively, as we had predicted."

Mr Jafferis points out that the prototype is limited because tiny conducting threads anchor it to heavy batteries, so it's free to move only a few centimetres. But he is already working on a solar-powered upgrade that could freely fly over large distances.

The advantage of this kind of propulsion, he argues, is that unlike jets, propellers and hovercraft, there are no moving components like cogs and gears that rub against each other.

"The ideal use would be some kind of dusty, grimy environment where moving parts would get gummed up and stop," he explained.

That said, he laughingly admits that with the existing materials, a flying carpet powerful enough to carry a person would need a wingspan of 50 metres - not the best vehicle to take on the streets just yet.

On the other hand, preliminary calculations suggest that there is enough atmosphere on the planet Mars to send floating rovers scudding over its dusty surface.

Meanwhile, Prof Mahadevan looks forward to sophisticated improvements in the near future, suggesting the approach could progress to "mimicking the beautiful two-dimensional undulations of the skate or manta ray".

You can listen to Noah Jafferis describe his flying carpet on the BBC World Service programme Science in Action.

IBM now second biggest tech firm

For the first time since 1996 IBM's market value has exceeded Microsoft's.

IBM's closing price on 29 September was $214bn (�137.4bn) while Microsoft's was a shade behind at $213.2bn (�136.8bn).

The values cap a sustained period in which IBM's share price has moved steadily upward as Microsoft's has generally been in decline.

The growth means IBM is now the second largest technology company by market value. Apple still holds the top slot with a value of $362bn (�232bn).

Since the beginning of 2011, IBM's share price has made steady gains and is now 22% higher than at the start of the year, according to Bloomberg figures. By contrast, Microsoft's value has dropped 8.8% over the same time period.

Analysts put the switch in the number two slot down to a decision IBM made in 2005 to sell off its PC business to Chinese manufacturer Lenovo to concentrate on software and services.

"IBM went beyond technology," Ted Schadler, a Forrester Research analyst told Bloomberg. "They were early to recognise that computing was moving way beyond these boxes on our desks."

By contrast much of Microsoft's revenue comes from sales of Windows and Office software used on PCs. Also, Microsoft is between releases of Windows which can mean a fallow period for its revenues.

Windows 7 was released in 2009 and Windows 8 is not expected to be released until late 2012 at the earliest.

Many have also claimed that the rise of the web, mobile computing and tablets spells the end of the PC era. In early August, Dr Mark Dean, one of the designers of the original IBM PC, declared that the centre of the computing world had shifted away from the humble desktop.

ISPs face broadband ad overhaul

ISPs face changes to the way they advertise broadband services.

From April next year, providers will no longer be able to advertise maximum speeds for net packages unless 10% of customers can actually get them.

The new rules come from the Committees of Advertising Practice (CAP), the body responsible for writing advertising codes.

But Which?, one of the main campaigners for change, said the new rulings do not go far enough.

Typical speeds

There has been huge pressure from industry and consumer groups for changes in the way broadband services are marketed with many feeling current campaigns are misleading consumers.

"This new guidance directly responds to consumer concerns by setting an appropriately high bar for advertisers who want to make speed and unlimited claims in ads," said CAP chairman James Best.

"Advertising is only effective if consumers trust the messages they see and hear," he added.

The new rules state that services cannot be advertised with a headline speed, unless 10% of customers can achieve that. It also calls on ISPs to be clearer about the data caps they set for services.

Which did not think the guidelines went far enough.

"Broadband providers have just been given the green light to mislead consumers. The rules say that providers don't have to state what range of speeds most of their customers experience," it said in a statement.

"That means advertising campaigns can now be based on the experience of a privileged few. If just one in 10 customers get access to the top speeds advertised, that's within the guidelines," it said in a statement.

A recent study by Ofcom found that many services marketed as up to 20Mbps actually achieved an average of just 6.8Mbps.

It recommended that ISPs advertise "typical" speeds so that consumers would have a clearer idea of what they were getting.

"We are disappointed that it appears not to be possible to establish a single, clear and consistent 'Typical Speed Range'. Our view is that this is the best way to ensure that consumers are able to compare the wide range of packages that are available," it said in response to the new guidelines.

CAP also looked at the way ISPs advertise services as unlimited even though they impose data thresholds.

It ruled that broadband providers could still impose limits on the amount of data that users could download, but they must explain the thresholds more clearly.

Catch-all claims

Which? was unimpressed.

"Unlimited should mean unlimited at your normal broadband speed, but internet service providers will be allowed to slow down a supposedly 'unlimited' connection once a customer goes over a certain threshold," it said.

"Ofcom should step in where the advertising regulators have failed, and make sure consumers can't be misled about the broadband service they're paying for," it added.

Virgin, which has campaigned for changes in the way its rival advertise services, said it was pleased with the new codes.

Jon James, executive director of broadband at Virgin Media, said: "This is a much needed and long awaited victory for consumers. The new rules are a big step in the right direction and the greater transparency will ensure people can make more informed choices.

ISPs will no longer be able to hide behind generic terms or catch-all claims which they simply cannot deliver."

Bio-inspired plastic self-heals

The development of self-healing materials has surged forward as scientists have taken inspiration from biological systems.

Researchers at the University of Illinois in the US have found a way to pump healing fluids around a material like the circulation of animal's blood.

Materials that could repair themselves as they crack would have uses in civil engineering and construction.

Their results are published in the Journal of the Royal Society Interface.

Self-healing materials have been researched for nearly a decade, with a view to reducing the risks and costs of cracking and damage in a wide range of materials.

Different approaches have been taken to creating such materials, depending on the kind of material that needs to be repaired: metals, plastics, or carbon composites.

These methods include creating materials which have micro-capsules containing a healing agent embedded within them, which are broken open when the material is damaged, releasing the healing fluid that hardens and fills the crack.

While effective, this method and others are limited by the small amount of healing agent that can be contained within the material without weakening it.

But new developments in self-healing technology have been pioneered by Prof Nancy Sottos and her team at the University of Illinois Urbana-Champaign, involving the impregnation of plastics with a fine network of channels, each less than 100 millionths of a metre in diameter, that can be filled with liquid resins.

These "micro-vascular" networks penetrate the material like an animal's circulation system, supplying healing agent to all areas, ready to be released whenever and wherever a crack appears.

Limitations still blight this technology however, as the healing process relies on the slow wicking action and diffusion of the healing agent into a crack.

The researchers have therefore taken another lesson from biology to improve on the self-healing material's performance.

Cracking experiment

"In a biological system, fluids are pumping and flowing," said Prof Sottos, so they have devised a way to actively pump fluids into their micro-vascular networks.

Syringes on the outside of the material put healing fluids under pressure so that when a crack appears, a constant pressure drives the fluid into the cracks.

In the experiments that Prof Sottos' team carried out, two parallel channels are created in a plastic and pumped with a liquid resin and a hardening chemical that triggers the resin to solidify.

When a crack forms, both micro-channels are breached and the two liquids are pumped into the damaged area.

The researchers experimented with pumping the liquids in pulses so that first the resin was pushed into the crack, and then the hardener, in repeating cycles.

This, they found, was the most efficient way of filling large cracks and ensuring the widest spread of the healing agents.

"Micro-capsule technology will enable damaged openings around 50-100 [millionths of a metre] to be filled, whereas pumping healing agents through a micro-vascular network can fill major cracks up to a millimetre across," said Prof Sottos.

Double duty

Having demonstrated the improved repair that an actively pressurised system provides, the researchers hope that the technology can be utilised in engineering and construction applications with a little further development.

The method of constructing the materials is already well refined, using 3-D scaffolds of "sacrificial fibres" that mould the network of channels within a synthetic material, that are then destroyed in the final stage of production.

In the experimental work that Prof Sottos and her group have carried out, the pumps have been on the outside of the material, but she explained: "We would like to incorporate pumps into the material itself, perhaps pressure or magnetically driven."

Many large-scale structures where self-healing materials would be most useful, for example in aeroplanes and spacecraft, already have hydraulic systems built into them.

Prof Sottos envisaged these hydraulic systems being harnessed to perform a "double duty" in providing pressure for their self-healing materials.

The team are next looking into how the self-healing system can be integrated seamlessly into large-scale civil infrastructures, and how it can be optimised to provide the most healing potential.

Amazon unveils Kindle Fire tablet

Amazon has unveiled a colour tablet computer called the Kindle Fire.

The $199 (�130) device will run a modified version of Google's Android operating system.

Until now, the company has limited itself to making black and white e-readers, designed for consuming books and magazines.

As well as targeting Apple's iPad, Amazon is likely to have its sights on rival bookseller US Barnes & Noble, which already has a colour tablet.

The Kindle Fire will enter a hugely competitive market, dominated by Apple's iPad.

Amazon will be hoping to leverage both the strength of the Kindle brand, built up over three generations of its popular e-book reader, and its ability to serve up content such as music and video.

In recent years, the company has begun offering downloadable music for sale, and also has a streaming video-on-demand service in the United States. Those, combined with its mobile application store, give it a more sophisticated content "ecosystem" than most of its rivals.

Lower priced

Digital content has already proved itself to be a money-spinner for Amazon.

Although the company has never released official sales figures for the Kindle, it did state - in December 2010 - that it was now selling more electronic copies of books than paper copies.

Its US rival, Barnes & Noble, has also enjoyed success with its Nook devices.

In October 2010, the company unveiled the Nook Color, which also runs a version of Android, albeit with lower hardware specs than many fully featured tablets.

While the Nook Color is largely focused on book and magazine reading, some users have managed to unlock its wider functionality and install third-party apps.

The Kindle Fire's $199 (�130) price tag undercuts the Nook Color by $50 (�30) and is significantly cheaper than more powerful tablets from Apple, Samsung, Motorola and others.

It is due to go on sale on 15 November in the US, although global release dates are currently unavailable.

Google boosts Silicon Roundabout

Google is to provide office space and assistance to new technology companies in London's "Silicon Roundabout".

The company has leased a seven-storey building in the Old Street area, where many start-up firms are based.

Prime Minister David Cameron has signalled his desire to turn the area into "one of the world's great technology centres".

About 300 companies are now working in the area, according to Tech City, the body set up to promote the initiative.

Google said that the building, in Bonhill Street, would host "a range of activities, such as speaker series, hackathons, training workshops and product demonstrations" in addition to providing workspace for new companies.

The California-based company stressed that it was not moving its UK headquarters - currently in central London - to the area.

Many millionaires

Eric Van Der Kleij, chief executive of the Tech City Investment Organisation, said that partnering established technology companies with fresh talent could be beneficial to both parties.

<!-- pullout-items--> <!-- pullout-body-->

Google's Innovation Hub may be a "creative space" - but there's no sign that its researchers will be spending any time there creating anything new.

To be fair, the company's press release stresses that is just the first stage in making its commitment to Tech City a reality.

So, yes, it's a good day for east London's technology ambitions.

But if the vision outlined by the prime minister is to be realised, then the area will need to see companies like Google, Intel and Cisco fill the lofts and warehouses around the Silicon Roundabout with engineers as well as events organisers.

<!-- pullout-links-->

"What [companies like Google] do by having a firm footing in the community is provide a channel for innovation, to partner with them and potentially even sell to them," he told BBC News.

"It accelerates the process of the entrepreneur doing a tech startup, selling for a lot of money, creating a lot of millionaires within their organisation and creating recyclable wealth - then going out to do more innovation."

Large corporations have been lending support to young entrepreneurs in the area for some time.

The nearby Tech Hub project, which offers accommodation and business support, is supported by Google, media group Pearson and software firm BlueVia.

Telecoms companies, including BR and Virgin Media are also making the area a priority for installing ultra-fast broadband connections.

The Silicon Roundabout initiative has been championed by the prime minister as a model for developing the UK's knowledge economy.

Speaking in November 2010, David Cameron said that it was possible to learn lessons from Silicon Valley in the US.

"Go with the grain of what is already there. Don't interfere so much that you smother. But do help out wherever you can.

"Help to create the right framework, so it's easier for new companies to start up, for venture capital firms to invest, for innovations to flourish, for businesses to grow," said the prime minister.

Google expects its new East London Facility to open in 2012, following a major refurbishment.

US to probe HTC&#39;s Apple complaint

A US trade watchdog will investigate a claim by Taiwanese phone firm HTC that its rival Apple has infringed its patents.

HTC filed the complaint with the US International Trade Commission (USITC) in August.

It is one of three that HTC has filed against Apple.

Apple has also accused HTC of copying its technology, and other global companies are also involved in what is being called a global patent war.

Korea's Samsung is currently fighting Apple in a number of European courts, as well as Australia.

In HTC's claim, which the US International Trade Commission (USITC) will investigate, the Taiwanese firm alleges that Apple has infringed its patents in smart phones, tablet computers and computers.

HTC is seeking to block the import of Apple products into the US.

Three pleads for spectrum share

Mobile firm Three has warned that it may begin running out of capacity in urban areas by the end of next year if spectrum auctions do not go ahead.

Networks increasingly face congestion as the demand for data soars.

Auctions to free up space for next generation mobile services are earmarked for mid-2012 although Three said that the timetable was "already slipping".

It said it was vital the firm got its fair share of new spectrum.

It also warned that its rivals may attempt to delay the process.

"There is a huge financial incentive for rival operators to delay the auction. We are worried that the other three will attempt to squeeze us out of the market," said Three chief executive David Dyson at a press briefing in London.

Ofcom is due to re-evaluate the fees operators pay for 2G spectrum once the auction is complete.

"The more that is bid for new spectrum the more operators will pay in fees for existing spectrum. They will only start paying the fees from the end of the auction so there is an incentive to delay it," explained Ovum analyst Matthew Howett.

Spectrum allocation in the UK is hugely complex. Historically O2 and Vodafone own all the UK's 2G airwaves because they were the only operators in the market when that spectrum was handed out.

While other European countries have reallocated their 2G spectrum among newer players that hasn't happened in the UK.

Earlier this year Ofcom agreed to allow O2 and Vodafone to re-use parts of the 2G network for 3G services.

While it eased capacity issues for them, it led Three to complain that the playing field for mobile operators was becoming increasingly uneven.

As a sweetener, Ofcom said that it would impose a cap on the amount of spectrum companies could win at the auction to ensure 3 remained a key player in the market.

"It has made it clear that it wants Three in the market and that it values Three's disruptive influence," said Mr Howett.

Rivals are not happy and have threatened legal action over the caps.

"They argue that it is legal state aid," said Mr Howett.

O2 is awaiting the final details of how the auction will work - expected from Ofcom in November - but did not rule out the possibility of further challenges.

"We are focused on a constructive and ongoing dialogue with Ofcom on its proposals. Even if some further consultation is required, it won't delay the availability of 4G, as the spectrum itself will not be available until 2013. The key is to get the auction right," said an O2 spokesperson.

The 4G auctions will sell off spectrum in the 800MHz and 2.6GHz bandwidths.

The first has been freed up by the switchover to digital TV and is particularly valuable to operators because its low frequency means it can cover larger areas and penetrate buildings.

Three currently has the poorest in-building coverage of all the operators.

The huge demand for data has been putting the squeeze on all networks, particularly Three, and the 2.6GHz band will help ease such issues.

Mr Dyson admitted that capacity in large urban areas such as London would begin to run out by the end of next year but he remains confident it won't affect customers.

"I believe the auction will go ahead next year and therefore congestion will not happen," he said.

"We have been assured by the government and Ofcom that distortions will be rebalanced when the auction happens," he said.

But he added that the timetable for the auction process was already slipping.

"Ofcom originally planed to come back to industry with its plans in September or October but that is now likely to be the end of the year or the beginning of the next," he said.

But Mr Howett remains convinced the delays will not affect the auction.

"It is a hugely ambitious timetable, trying to do in 18 months what took three years for 3G, but most are optimistic it can still be met," he said.

Whether rivals will take the legal action they have threatened remains to be seen but pressure will be put on them to push ahead with the process.

"Jeremy Hunt has said that he doesn't want it to be delayed and they will have him breathing down their necks saying 'don't get in the way'", said Mr Howett.

As part of its push to make data more available, Three is dropping the price of its popular all-you-can-eat data plan to �18 a month.

&#39;Smart&#39; window to save energy

A new type of "smart" window that switches from summer to winter mode has been made by South Korean scientists.

The window darkens when the outside air temperatures soar, and becomes transparent when it gets cold in order to capture free heat from the sun.

Similar windows already exist, but the researchers say their method allows for an almost instantenous switch from opaque to transparent.

This may help save more energy, the team writes in the journal ACS Nano.

"This type of light control system may provide a new option for saving on heating, cooling and lighting costs through managing the light transmitted into the interior of a house," said the scientists.

"Smart windows can prevent the inside of a building from becoming overheated by reflecting away a large fraction of the incident sunlight in summer.

"Alternatively, they can help keep a room warm by absorbing the sun's heat in winter."

New approach

The existing technology uses charged particles called ions sandwiched between panes of glass.

Electric current is then applied to switch the window from opaque to clear and back.

"Start Quote

[If] you're allowing light in much quicker, this can reduce the amount of heat loss out of houses or increase the cooling in summer"

End Quote Dr Steven Morris Technology Strategy Board

But Ho Sun Lim from Korea Electronics Technology Institute, Jeong Ho Cho and Jooyong Kim from Soongsil University decided on a different approach.

They used a special polymer, a different sort of charged particles known as counterions and solvents such as methanol.

The report states that the result was a glass that was a lot cheaper to manufacture and much less toxic than those currently available on the market.

The window is able to switch from 100% opaque to almost completely clear in a matter of seconds, said the authors.

Instantaneous switch

Although "dimming" windows already exist, it is often necessary to switch them from winter to summer mode and back manually, using additional equipment such as home-automation panels.

"Until now, the numerous technologies developed not only have been chemically unstable, prohibiting their use in long-term switching applications but have been accompanied by the use of expensive special equipment and complicated harsh processing conditions," stated the report.

Dr Stephen Morris from the UK's Technology Strategy Board said that if the new method allows the window to switch from opaque to transparent and back pretty much instantaneously, then it is going to be a real benefit in terms of energy savings.

"That would mean that you're allowing light in much quicker - and this can reduce the amount of heat loss out of houses or increase the cooling in summer," he said.
