Apple wins HTC graphic patent row

A US agency has ruled that Apple did not violate graphic patents owned by S3 Graphics, a unit of Taiwan's HTC.

S3, which makes image compression technology, filed a complaint with trade agency, ITC, in May 2010.

The company accused Apple of infringing four patents, which it said were used widely in a range of Apple products.

Apple is embroiled in numerous patent disputes in many countries, most famously with Samsung.

The US International Trade Commission (ITC) said its investigation into the matter between Apple and S3 had been terminated.

Shares in HTC, which purchased S3 in July, fell 4.9% on the news.

In July, an ITC judge had ruled that Apple infringed some of the patents.

The latest ruling reverses the earlier decision.

The ITC is an agency that has the power to block the import of products into the United States that it believes violate patents.

Bionic lenses to project emails

A new generation of contact lenses that project images in front of the eyes is a step closer after successful animal trials, say scientists.

The technology could allow wearers to read floating texts and emails or augment their sight with computer-generated images, Terminator-syle.

Researchers at Washington University who are working on the device say early tests show it is safe and feasible.

But there are still wrinkles to iron out, like finding a good power source.

Currently, their crude prototype device can only work if it is within centimetres of the wireless battery.

And its microcircuitry is only enough for one light-emitting diode, reports the Journal of Micromechanics and Microengineering.

"Start Quote

Our next goal is to incorporate some predetermined text in the contact lens"

End Quote Lead researcher Professor Babak Praviz

But now that initial safety tests in rabbits have gone well, with no obvious adverse effects, the researchers have renewed faith about the device's possibilities.

They envisage hundreds more pixels could be embedded in the flexible lens to produce complex holographic images.

For example, drivers could wear them to see journey directions or their vehicle's speed projected onto the windscreen.

Similarly, the lenses could take the virtual world of video gaming to a new level.

They could also provide up-to-date medical information like blood sugar levels by linking to biosensors in the wearer's body.

Delicate materials

Lead researcher Professor Babak Praviz said: "Our next goal is to incorporate some predetermined text in the contact lens."

He said his team had already overcome a major hurdle to this, which is getting the human eye to focus on an image generated on its surface.

Normally, we can only see objects clearly if they are held several centimetres away from the eye.

The scientists, working with colleagues at Aalto University in Finland, have now adapted the lenses to shorten the focal distance.

Building the end product was a challenge because materials used to make conventional contact lenses are delicate.

Manufacturing electrical circuits, however, involves inorganic materials, scorching temperatures and toxic chemicals. Researchers built the circuits from layers of metal only a few nanometres thick, about one thousandth the width of a human hair, and constructed light-emitting diodes measuring one third of a millimetre across.

Dr Praviz and his team are not the only scientists working on this type of technology.

A Swiss company called Sensimed has already brought to market a smart contact lens that uses inbuilt computer technology to monitor pressure inside the eye to keep tabs on the eye condition glaucoma.

Hackers 'attack' US water system

Hackers are alleged to have destroyed a pump used to pipe water to thousands of homes in a US city in Illinois.

Hackers with access to the utility's network are thought to have broken the pump by turning it on and off quickly.

The FBI and Department for Homeland Security (DHS) are investigating the incident as details emerge of what could be a separate second attack.

Experts said the news revealed a growing interest in critical infrastructure by cyber criminals.

Information about the 8 November incident came to light via the blog of Joe Weiss who advises utilities on how to protect hardware against attack.

Mr Weiss quoted from a short report by the Illinois Statewide Terrorism and Intelligence Center which said hackers obtained access using stolen login names and passwords. These were taken from a company which writes control software for industrial systems.

The net address through which the attack was carried out was traced to Russia, according to Mr Weiss. The report said "glitches" in the remote access system for the pump had been noticed for months before the burn out, said Mr Weiss.

Peter Boogaard, A spokesman for the DHS, said it was gathering facts about the incident.

"At this time there is no credible corroborated data that indicates a risk to critical infrastructure entities or a threat to public safety," he said.

Industrial action

The comments by the DHS prompted a hacker using the handle "pr0f" to claim he had access to the control systems for a second US water utility.

He posted a document to the Pastebin website which purportedly contained links to screenshots of the internal control systems for a waste water treatment plant in South Houston.

The hacker's claims about their ability to penetrate the control systems have yet to be confirmed or denied by South Houston's Water and Sewer Department.

In an interview with the Threat Post website, Pr0f said the hack of the South Houston network barely deserved the name because only a three-character password had been used to protect the system.

The attacks are the latest in a series in which different hackers and groups have targeted so called Supervisory Control And Data Acquisition (SCADA) systems. These specialised computer systems are used to control machinery used to filter water, mix chemicals, generate power and route trains and trams.

One of the best known SCADA attacks involved the Stuxnet worm which caused problems for Iran.

There were reports that the malware crippled centrifuges used in the nation's uranium enrichment program. Iran denied the claims saying that it had caught the worm before it reached its intended target.

Earlier this year, security researchers who investigated ways to attack SCADA systems were persuaded to cancel a public talk about their findings because of the "serious physical, financial impact these issues could have on a worldwide basis".

Lani Kass, a former advisor to the US Joint Chiefs of Staff on security issues, said America had to start doing more work to understand attacks on critical infrastructure.

"The going in hypothesis is always that it's just an incident or coincidence," she said. "And if every incident is seen in isolation, it's hard - if not impossible - to discern a pattern or connect the dots."

"Failure to connect the dots led us to be surprised on 9/11," she said.

Sony clamps down on game sharing

UK gamers can no longer play the same copy of a new PlayStation Store game on more than two devices.

On 18 November Sony cut the number of consoles and handheld devices that users can tie to their PlayStation Network (PSN) account from five to two.

The change only applies to games and other content bought via the PlayStation Store after 18 November.

The limits are believed to have been imposed to stop people sharing games with friends.

Sony unveiled the changes via a blog posting in which it said that PS3 users will only be able to use their games on two activated PS3 consoles. Similarly, games for the PlayStation Portable will only be playable on two of the handheld gadgets.

This means that a single PSN account will be able to support a maximum of two consoles and two handhelds.

The electronics firm said it was setting up account management pages for PSN users through which they will be able to decide on which consoles or handhelds their games can be played.

Prior to the 18 November change, up to five different PlayStation consoles could be connected to a PSN account and used to play games. Many gamers used this to activate consoles of their friends effectively giving them free access to games.

Eurogamer news editor Wesley Yin-Poole said the change had not prompted a backlash.

"It's only a problem to those who share downloaded games and have multiple devices in the home, but that's a minority of users," he said. "Most players use a single PlayStation 3 and a single PlayStation Portable, if that."

He said it was a move intended to support the upcoming launch of the PlayStation Vita which will count as one of the activated devices.

The changes apply to gamers based in the UK, Australia, Ireland, New Zealand and the Middle East. However, it is thought the policy will soon be applied to other territories including the key markets of Japan and the US.

World's 'lightest material' claim

A team of engineers claims to have created the world's lightest material.

The substance is made out of tiny hollow metallic tubes arranged into a micro-lattice - a criss-crossing diagonal pattern with small open spaces between the tubes.

The researchers say the material is 100 times lighter than Styrofoam and has "extraordinarily high energy absorption" properties.

Potential uses include next-generation batteries and shock absorbers.

The research was carried out at the University of California, Irvine and HRL Laboratories and is published in the latest edition of Science.

"The trick is to fabricate a lattice of interconnected hollow tubes with a wall thickness 1,000 times thinner than a human hair," said lead author Dr Tobias Schaedler.

Low-density

The resulting material has a density of 0.9 milligrams per cubic centimetre.

By comparison the density of silica aerogels - the world's lightest solid materials - is only as low as 1.0mg per cubic cm.

The metallic micro-lattices have the edge because they consist of 99.99% air and of 0.01% solids.

The engineers say the material's strength derives from the ordered nature of its lattice design.

By contrast, other ultralight substances, including aerogels and metallic foams, have random cellular structures. This means they are less stiff, strong, energy absorptive or conductive than the bulk of the raw materials that they are made out of.

William Carter, manager of architected materials at HRL, compared the new material to larger low-density structures.

"Modern buildings, exemplified by the Eiffel Tower or the Golden Gate Bridge are incredibly light and weight-efficient by virtue of their architecture," he said.

"We are revolutionising lightweight materials by bringing this concept to the nano and micro scales."

Robust

To study the strength of the metallic micro-lattices the team compressed them until they were half as thick.

After removing the load the substance recovered 98% of its original height and resumed its original shape.

The first time the stress test was carried out and repeated the material became less stiff and strong, but the team says that further compressions made very little difference.

"Materials actually get stronger as the dimensions are reduced to the nanoscale," said team member Lorenzo Valdevit.

"Combine this with the possibility of tailoring the architecture of the micro-lattice and you have a unique cellular material."

The engineers suggest practical uses for the substance include thermal insulation, battery electrodes and products that need to dampen sound, vibration and shock energy.

Robots set out to sample the seas

Four robots have set out on an epic 33,000 nautical mile (66,000km) journey across the Pacific Ocean.

Created by US firm Liquid Robotics, the four are aiming to set the record for the longest distance at sea travelled by an unmanned craft.

Throughout their journey the robots will gather lots of data about the composition and quality of sea water.

The journey is expected to take about 300 days, and is designed to inspire researchers to study ocean health.

The robots were launched from the St Francis Yacht Club on the edge of San Francisco harbour on 17 November.

Initially the four will travel as a flotilla to Hawaii and then will split into two pairs. One will go on to Australia and the other will head to Japan to support a dive on the Mariana Trench - the deepest part of the ocean.

The robots manage to move thanks to interaction between the two halves of the autonomous vehicle. The upper half of the wave-riding robot is shaped like a stunted surfboard and it is attached by a cable to a lower part that sports a series of fins and a keel.

Sensor readings

Interaction between the two parts brought about by the motion of the waves enables the robot to propel itself.

Electrical power for sensors is provided by solar panels on the upper surface of the robot.

On their epic journey, the four robots will take sensor readings every 10 minutes to sample salinity, water temperature, weather, fluorescence, and dissolved oxygen.

About 2.25 million data points will be gathered during the voyage and the wandering route they will take passes through regions never before surveyed.

The data set will be fed back as it is gathered and then shared with anyone that registers their interest with Liquid Robotics.

The company is also seeking innovative suggestions about what to do with the data being gathered. The winning entry in this competition will win six months of access to the wave-riding robots to complete the research.

The wave-riding robots are veterans of ocean-going science and helped monitor the spread of oil during the Deepwater Horizon spill in the Gulf of Mexico. Before now the longest single journey they have undertaken was over a distance of 2,500 miles.

Data spies raid Norwegian firms

Oil, gas and defence firms in Norway have been hit by a series of sophisticated hack attacks.

Industrial secrets and information about contract negotiations had been stolen, said Norway's National Security Agency (NSM).

It said 10 firms, and perhaps many more, had been targeted in the biggest wave of attacks to hit the country.

Norway is the latest in a growing list of nations that have lost secrets and intellectual property to cyber thieves.

The attackers won access to corporate networks using customised emails with viruses attached which did not trigger anti-malware detection systems.

Targeted attacks

The NSM said the email messages had been sent to specific named individuals in the target firms and had been carefully crafted to look like they had come from legitimate sources.

Many of the virus-laden emails were sent while the companies were in the middle of negotiations over big contracts.

It said user names, passwords, industrial drawings, contracts and documents had been stolen and taken out of the country.

The NSM believes the attacks are the work of one group, based on its analysis of the methods used to target individuals, code inside the viruses and how the data was extracted.

The agency said it was publishing information about the attacks to serve as a warning and to encourage other targeted firms to come forward.

"This is the first time Norway has revealed extensive and wide computer espionage attacks," the NSM said in a statement.

Singled out

It said it found out about the attacks when "vigilant users" told internal IT security staff, who then informed the agency.

However, the NSM said, it was likely that many of the companies that had been hit did not know that hackers had penetrated their systems and stolen documents.

Security firms report that many other nations and industrial sectors have been targeted by data thieves in recent months.

The chemical industry, hi-tech firms and utilities appear to have been singled out.

Smartphone data tariff warning

BlackBerry <!-- Empty - Wide embedded hyper -->

Mobile phone operators must do more to help people avoid getting unexpectedly large bills after going online, says the Communications Ombudsman.

The complaints watchdog says so-called data download bill shock is a serious and growing problem.

Chief Ombudsman Lewis Shand Smith says that is because it is becoming more common for people to download big files, like videos, onto mobiles.

He says that has led to a rise in the number of customers being affected.

Adam Barclay-Faulkner, who's 27, runs his own small business selling big, inflatable adverts in Staffordshire.

He says he makes the most of his mobile's unlimited data deal.

He said: "Mainly I use my mobile for Facebook to keep in touch with family and friends.

"I also send and receive a lot of work emails and watch the occasional video as well."

Big bills

Like many people Adam thought he was on an unlimited data deal with his mobile operator.

As can often be the case though, there was a limit which was in the small print of the contract.

Adam Barclay-Faulkner Adam says he got a bill for �160 more than he was expecting

When he went over that limit Adam started getting charged extra.

Adam says that led to a bill of around �200 instead of his regular monthly one for �38.

"We're in a recession and I don't have the money to just throw at things like this," said Adam.

The unintended overspend led to him being cut off until he could pay his bill.

He says that meant missed emails and lost work.

"I'm the main point of call in my business," he said. "It's really difficult to not have something for a few days before they decided to reconnect me after I'd paid it."

Advice

As technology improves it is becoming more coommon for people download bigger files.

Those inlcude songs, videos and emails with large attachments.

Communications Ombudsman Lewis Shand Smith thinks phone companies could do more to warn people but says they are doing nothing wrong under the current regulations.

He said: "Most mobile operators are playing by the rules, so that then begs the question are the rules what they ought to be?"

Customer satisfaction is always a priority and there are several ways people can keep track of exactly how much data they use

Big five mobile phone operators

He's calling on mobile phone operators to do three things.

"First of all, be very clear about what they mean by unlimited in the advertisements," he advised.

"Secondly, give advice to consumers so they know when they're reaching their limit.

"And thirdly, give advice on the amount of data that's being downloading."

In a series of statements the big five mobile phone operators said: "There are a variety of different tariffs and deals that let customers manage their bills effectively.

"Customer satisfaction is always a priority and there are several ways people can keep track of exactly how much data they use."

Depending on your download connection the amount of data you use for one song is roughly 3 megabytes, for a three-minute video it's 15 megabytes and for a half hour TV show it's around 350 megbytes.

AP writers told off for tweeting

Associated Press has reprimanded some of its journalists for breaking news on Twitter before posting it on the wires.

The news agency issued the warning after some staff members tweeted that AP journalists had been arrested at the Occupy Wall Street camp in Manhattan.

An email from bosses followed reminding staff about AP's social media policies.

The incident has reopened a debate about how traditional media deal with the disruptive nature of social networks.

Twitter has become a breaking news service for many people but it lacks the traditional outlets' reputation for accuracy. Because anyone can break stories on the platform they do not always turn out to be correct.

While Twitter is an invaluable tool in newsrooms around the world, it has also forced news organisations, including AP, to draw up strict rules.

"If you have a piece of information, a photo or a video that is compelling, exclusive and/or urgent enough to be considered breaking news, you should file it to the wire, and photo and video points before you consider putting it out on social media," the AP policy reads.

After the recent incident in New York, AP's managing editor Lou Ferrara wrote an email to employees explaining that their first duty was to the agency not Twitter.

And executive editor Kathleen Carroll issued a memo saying much of the resulting "chatter" had missed the point.

"When we lose contact with a journalist, our main focus is making sure they are safe, no matter where they are. Sometimes, talking about it while things are still uncertain can endanger them," she said.

"It's not outlandish to think that a tweet that's taken by someone in authority to be opinionated or sarcastic could lead to one of our staffers being held longer than necessary."

She added that AP policies on using Twitter and other social media platforms were there "for good reasons".

Extinction

"Start Quote

To bury our head in the sand and act like Twitter isn't increasingly becoming the source of what informs people in real-time is ridiculous,""

End Quote Anthony de Rosa Social media editor, Reuters

But Anthony de Rosa, social media editor at Reuters, thinks that such policies may need to be overhauled.

He tweeted: "News agencies must evolve or face extinction."

He expanded the point in his official Reuters blog.

"The wire is still a huge part of our business and always will be. However, acting in a way that handcuffs us from doing our best work on Reuters.com and on social networks, which help drive traffic and extend our brand, is writing a death sentence for us as a future media company.

"To bury our head in the sand and act like Twitter (and who knows what else comes into existence next month or five years from now?) isn't increasingly becoming the source of what informs people in real-time is ridiculous," he wrote.

One of the biggest issues that corporations have to face is that Twitter and Facebook are used by employees for both personal and professional reasons.

Mr de Rosa believes this can improve news agencies' brands.

"Part of having your journalists on these platforms is giving them the freedom to be a normal human being, not a robot, a PR machine or a slave to the wire," he blogged.

Caroline Kean, a partner with law firm Wiggin, thinks social media policies need to take into account that people are writing on such platforms as both professionals and individuals.

"Employees of a news organisation have an obligation to break stories via their employer rather than to the world at large and it is easy to see that if a company's whole business model is built on breaking news then doing that on Twitter undermines that business," she said.

But if there are also personal reasons for tweeting, such as journalists being arrested, then common-sense can be applied.

"It is possible to write a personal tweet while protecting the agency story," she said.

The BBC has also had to consider the issue.

News website editor Steve Herrmann said: "We have guidance on the personal use of social media, for example staff should be careful that the information disclosed or opinions expressed do not bring the BBC into disrepute. It is based on common sense, and could almost be boiled down to 'Don't do anything stupid'".�

Cruel hoax

Mr Herrmann believes news organisations need to raise their game.

"I think the speed and immediacy of Twitter is something newsrooms are still coming to terms with. In BBC News we are looking at how to make sure we have the best systems to ensure our reporting is available as fast as possible across all our services, whilst maintaining our commitment to accuracy, and Twitter is certainly forcing the pace," said Mr Herrmann.

The corporation aims to get breaking news on both platforms at the same time although some stories, including exclusives by the BBC's business correspondent Robert Peston, have appeared on Twitter first.

Social media networks have proven their ability to distribute news at speed. Michael Jackson's death, for example, was widely reported on Twitter some time before traditional media caught up.

But reporting the deaths of celebrities carries its own health warning.

Earlier this month tweets began to spread about the death of Radio Clyde DJ Tiger Tim Stevens.

Eventually the DJ himself tweeted that he was "alive and well" and that the original tweet had been a "cruel hoax" that was particularly upsetting for his 91-year-old mother.

AI moves closer with brain chip

Scientists are getting closer to the dream of creating computer systems that can replicate the brain.

Researchers at the Massachusetts Institute of Technology have designed a computer chip that mimics how the brain's neurons adapt in response to new information.

Such chips could eventually enable communication between artificially created body parts and the brain.

It could also pave the way for artificial intelligence devices.

There are about 100 billion neurons in the brain, each of which forms synapses - the connections between neurons that allow information to flow - with many other neurons.

This process is known as plasticity and is believed to underpin many brain functions, such as learning and memory.

Neural functions

The MIT team, led by research scientist Chi-Sang Poon, has been able to design a computer chip that can simulate the activity of a single brain synapse.

Activity in the synapses relies on so-called ion channels which control the flow of charged atoms such as sodium, potassium and calcium.

The 'brain chip' has about 400 transistors and is wired up to replicate the circuitry of the brain.

Current flows through the transistors in the same way as ions flow through ion channels in a brain cell.

"We can tweak the parameters of the circuit to match specific ions channels... We now have a way to capture each and every ionic process that's going on in a neuron," said Mr Poon.

Neurobiologists seem to be impressed.

It represents "a significant advance in the efforts to incorporate what we know about the biology of neurons and synaptic plasticity onto ...chips," said Dean Buonomano, a professor of neurobiology at the University of California.

"The level of biological realism is impressive," he added.

The team plans to use their chip to build systems to model specific neural functions, such as visual processing.

Such systems could be much faster than computers which take hours or even days to simulate a brain circuit. The chip could ultimately prove to be even faster than the biological process.
