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."

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

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.
