Tesla Updates Charging Software

Tesla Motors Inc is making changes to prevent overheating of its charging systems, including giving customers upgraded wall adapters and providing charging-software upgrades, the electric-car company said on Friday.

The moves come after a November garage fire involving a Model S in Irvine, California, which the Orange County Fire Authority said may have been caused by a Tesla charging system or by a connection at the electricity panel on the wall of the garage.

At the time, Tesla disagreed with the fire officials’ findings, denying that the charging electronics were related to the fire. A Tesla spokeswoman did not immediately respond to a question on Friday about whether the upgrades were related to the Irvine fire.

In a Friday press release, Tesla said that its goal was to prevent excessive heating of the adapters used to charge its cars. A variety of factors ranging from corrosion to inappropriate wiring of electrical outlets can cause overheating, the company said.

A December tweak to its charging software tackles the issue through reducing charging by 25 percent if the charging system detects fluctuations in power entering the vehicle, Tesla said.

“Tesla believes that this software update fully addresses any potential risks,” the release said. But as a precaution, it said it would make available an improved wall adapter with a thermal fuse for affected customers, staring in a few weeks.

Separately, three road fires in Model S sedans caused Tesla’s stock to fall sharply in October.

The fires occurred in Washington state, Tennessee and Mexico. In the U.S. incidents, Model S sedans caught fire after running over road debris. In Mexico, a Model S caught fire after striking a concrete wall.

On Friday, Tesla’s stock fell 1.23 percent to $145.72, up from levels under $120 in late November but down from its high of $194.50 in late September.

Bluetooth 4.1 Goes IPV6

The Bluetooth Special Interest Group (SIG) has announced Bluetooth 4.1, the first version of Bluetooth to lay the foundations for IPV6 capability.

The first hints of what the Bluetooth SIG had planned for this new version were revealed to The INQUIRER in October during our exclusive interview with Steve Hegenderfer at Appsworld. There, he revealed his aspirations for the Bluetooth protocol to become integral to the Internet of Things.

At the front end of Bluetooth 4.1, the biggest change for users is that the retry duration for lost devices has been increased to a full three minutes, so if you wander off with your wireless headphones still on, there’s more of a chance of being able to seamlessly carry on listening upon your return.

Behind the scenes, devices fitted with Bluetooth 4.1 will be able to act as both hub and end point. The advantage of this is that multiple devices can share information between them without going via the host device, so your smartwatch can talk to your heart monitor and send the combined data in a single transmission to your smartphone.

This sort of “pooling” of devices represents an “extranet of things”, and the technology can therefore be applied to a wider area in forming the “Internet of Things” too.

The other major additions are better isolation techniques to ensure that Bluetooth, which broadcasts on an unregulated band, doesn’t interfere either with itself or with signals from other protocols broadcasting at similar frequencies, including WiFi.

The Bluetooth protocol has retained complete backwards compatibility, so a new Bluetooth 4.1 enabled device will work seamlessly with a Bluetooth 1.0 dongle bought in a pound shop.

In addition, Bluetooth 4.0 devices can be Bluetooth 4.1 enabled through patches, so we should see some Bluetooth 4.1 enabled hardware arrive early in 2014.

Researchers Build Flying Robot

Researchers say they have assembled a flying robot. It’s not designed to fly like a bird or an insect, but was built to simulate the movements of a swimming jellyfish.

Scientists at New York University say they built the small, flying vehicle to move like the boneless, pulsating, water-dwelling jellyfish.

Leif Ristroph, a post-doctoral student at NYU and a lead researcher on the project, explained that previous flying robots were based on the flight of birds or insects, such as flies.

Last spring, for example, Harvard University researchers announced that they had built an insect-like robot that flies by flapping its wings. The flying robot is so small it has about 1/30th the weight of a U.S. penny.

Before the Harvard work was announced, researchers at the University of Sheffield and the University of Sussex in England worked together to study thebrains of honey bees in an attempt to build an autonomous flying robot.

By creating models of the systems in a bee’s brain that control vision and sense of smell, scientists hope to build a robot that would be able to sense and act as autonomously as a bee.

The problem with those designs, though, is that the flapping wing of a fly is inherently unstable, Ristroph noted.

“To stay in flight and to maneuver, a fly must constantly monitor its environment to sense every gust of wind or approaching predator, adjusting its flying motion to respond within fractions of a second,” Ristroph said. “To recreate that sort of complex control in a mechanical device — and to squeeze it into a small robotic frame — is extremely difficult.”

To get beyond those challenges, Ristroph built a prototype robot that is 8 centimeters wide and weighs two grams. The robot flies by flapping four wings arranged like petals on a flower that pulsate up and down, resembling the flying motion of a moth.

The machine, according to NYU, can hover and fly in a particular direction.

There is more work still to be done. Ristroph reported that his prototype doesn’t have a battery but is attached to an external power source. It also can’t steer, either autonomously or via remote control.

Chip Makers Going After Cars

Chip makers including Broadcom and Renesas Electronics are putting more focus on in-car entertainment with faster processors and networks for wireless HD movies and navigation, aiming to keep drivers informed and passengers entertained.

With PC sales slipping and the mobile device market proving highly competitive, chip makers are looking for greener pastures in other sectors like in-car entertainment and information.

From Renesas comes the R-Car M2 automotive SoC (System-on-a-Chip), which has enough power to handle simultaneous high-definition navigation, video and voice-controlled browsing.

The SoC is meant for use in mid-range systems. It features two ARM Cortex A-15 cores running at up to 1.5GHz and Renesas’ own SH-4A processor plus the PowerVR SGX544MP2 from Imagination Technologies for 3D graphics. This combination helps the M2 exceed the previous R-Car H1 with more than three times the CPU capacity and approximately six times better graphics performance.

Car makers that want to put a more advanced entertainment system in their upcoming models should go for the eight core R-Car H2 SoC, which was announced earlier this year. It is based on ARM’s big.LITTLE architecture, and uses four Cortex-A15 cores and another four Cortex-A7 cores.

The H2 will be able to handle four streams of 1080p video, including Blu-Ray at 60 frames per second, according to Renesas. Mass production is scheduled for the middle of next year, while the M2 won’t arrive in larger volumes until June 2015.

Broadcom on the other hand is seeking to drive better networking on the road. The company’s latest line of wireless chipsets for in-car connectivity uses the fast 802.11ac Wi-Fi wireless standard, which offers enough bandwidth for multiple displays and screen resolution of up to 1080p. Use of the 5GHz band for video allows it to coexist with Bluetooth hands-free calls on 2.4GHz, according Broadcom.

Broadcom has also implemented Wi-Fi Direct and Miracast. Wi-Fi Direct lets products such as smartphones, cameras and in this case in-car computers connect to one another without joining a traditional hotspot network, while Miracast lets users stream videos and share photos between smartphones, tablets and displays.

The BCM89335 Wi-Fi and Bluetooth Smart Ready combo chip and the BCM89071 Bluetooth and Bluetooth Smart Ready chip are now shipping in small volumes.

Is The Tesla Hackable?

It’s the curse of the connected car once it’s linked to the Internet, it’s, well, on the Internet. In the case of the Tesla Model S, this means that mischievous hackers could, in theory, control some functions of the vehicle and even snoop without the owner’s knowledge.

Tesla offers Android and iPhone apps for Model S owners, which can be used to check the vehicle’s battery, track its location and status, and tweak several other settings, like climate control and the sunroof. It can also be used to unlock the doors on the Model S.

Dell senior engineer George Reese says the REST API used by Tesla to provide access for Android and iPhone apps has several fairly serious security flaws, which could offer a way in for unscrupulous hackers.

According to an article written by Reese for O’Reilly, Tesla appears to have broken from accepted best practice when designing the API for the Model S.

“It’s flawed in a way that makes no sense. Tesla ignored most conventions around API authentication and wrote their own. As much as I talk about the downsides to OAuth (a standard for authenticating consumers of REST APIs–Twitter uses it), this scenario is one that screams for its use,” he wrote.

However, Reese notes, this is merely a potential attack vector, not one that could be immediately exploited. That said, a compromised website particularly one designed to provide “value-added services” via the API to Tesla drivers could prove highly damaging.

“I can … honk their horns, flash their lights, and open and close the sunroof. While none of this is catastrophic, it can certainly be surprising and distracting while someone is driving,” Reese wrote.

Automotive hacking has been posited by experts for some time, and several presentations at this year’s Defcon detailed fairly comprehensive methods of compromising some models.

Google Snubs Privacy

Search giant Google has told the British government it is immune to prosecution on privacy issues and it can do what it like. The US Company is accused of illegally snooping on its British customers by bypassing privacy settings on Apple devices, such as iPads, to track their browsing history.

A group of British people took Google to court but the search engine is trying to get the case thrown out. Its argument is that it is not subject to British privacy law because it is based in California. This is the second time that Google has tried to avoid British law by pretending to operate in another country. It has come under fire for failing to pay tax in the UK

Nick Pickles, director of Big Brother Watch, said: ‘It is deeply worrying for a company with millions of British users to be brazenly saying they do not regard themselves bound by UK law. Solicitor Dan Tench, of law firm Olswang, said this was another instance of Google being here when it suits them and not being here when it doesn’t. Ironically when the US ordered Google to stop what it was doing, it forced the search engine to pay a $22.5million to regulators.

There are some indications that Google may not get its way. In July the Information Commissioner’s Office told Google its privacy rules breached UK law so it will be very hard for it to stand up in court and say it didn’t.

Is This A Mobile First World?

Judging from the number of people engrossed in activities with their smartphones on the sidewalk, in their cars and in public places, mobile seems to have stolen our attention away from the wired Internet and traditional TV.

However, there is a ways to go before mobile platforms become the primary place where consumers turn for entertainment and getting things done, players at  CTIA Wireless trade show said.

Nokia Siemens Networks announced new capabilities in its network software to make video streams run more smoothly over mobile networks. Among other things, the enhancements can reduce video stalling by 90 percent, according to the company. But even Sandro Tavares, head of marketing for NSN’s Mobile Core business, sees “mobile-first” viewing habits as part of the future.

“Now that the networks are providing a better capacity, a better experience with mobile broadband, mobile-first will come,” Tavares said. “Because the experiences they have with the devices are so good, these devices … start to be their preferred screen, their first screen.

“This is a trend, and this is something that will not change,” Tavares said. But he thinks it’s too early to build networks assuming consumers will turn to tablets and phones as their primary sources of entertainment. “Do you have to be prepared for mobile-first now? Probably not. You have to be able to keep the pace.”

For AT&T, mobile-first is a top priority for its own internal apps, ensuring employees can do their jobs wherever they are, said Kris Rinne, the carrier’s senior vice president of network technologies. But to make it possible over the network, a range of new technologies and relationships may have to come together, she said.

For example, giving the best possible performance for streaming video and other uses of mobile may require steering traffic to the right network if both cellular and Wi-Fi are available. AT&T is developing an “intelligent network selection” capability to do this, Rinne said. When AT&T starts to deliver voice over LTE, it will stay on the cellular network — at least in the early days — because the carrier has more control over quality of service on that system, she said.

Other issues raised by mobile-first include security of packets going over the air and rights for content that subscribers are consuming primarily on mobile devices instead of through TV and other traditional channels, Rinne said.

Google Fights NSL Over Data Privacy

Google is fighting a National Security Letter (NSL) issued by the US government, with the Electronic Frontier Foundation (EFF) acknowledging it is one of the first firms to do so.

Google took the unusual step last month of revealing, albeit in vague terms, the number of NSLs it received from the US government. At the time the company said it was working with the authorities to improve transparency around the subject, but according to court filings it is also fighting against handing over users’ data.

In March, Google filed a petition to set aside a legal process. Kevan Fornasero, a lawyer for Google said in the filing that petitions “filed under Section 3511 of Title 18 to set aside legal process issued under Section 2709 of Title 18 must be filed under seal because Section 2709 prohibits disclosure of the legal process”.

Fornasero’s reference to Section 2709 refers to the ability of the FBI to issue NSLs and force the handover of user data. According to the EFF, Google is one of the first communications companies to fight an NSL, but because Section 2709 doesn’t allow firms to disclose the legal process, few people can be certain that others haven’t tried to stand up to the US government.

Matt Zimmerman, a lawyer for the EFF said, “The people who are in the best position to challenge the practice are people like Google. So far no one has really stood up for their users’ among large Internet service providers.”

Google has tried in recent years to provide users with some information on how it deals with government agencies’ requests for user data. If the firm can succeed in its fight against NSLs then it could open the floodgates for others to stand up against a law that some see to be nothing more than a snooper’s charter.

AT&T Gets GM

AT&T Monday said it will provide LTE wireless services to most General Motors automobiles starting in 2014 in the U.S. and Canada.

A multi-year agreement between AT&T and GM subsidiary OnStar calls for vehicles to continue getting OnStar’s safety and security services while adding information and entertainment services for backseat drivers, AT&T said.

Millions of vehicles will be affected, as AT&T rolls out LTE to reach 300 million people in the U.S. by the end of 2014.

The AT&T-GM announcement is part of an explosion in the number of devices connected to the Internet, many of them wirelessly, in what some have termed the “Internet of Things.”

“The is a big announcement for connected devices,” Glenn Lurie, president of emerging enterprises and partnerships at AT&T, said in an interview at Mobile World Congress here.

GM Adds IT Jobs

General Motors Co said on Monday it will add 1,500 jobs at a new software development center in Michigan as part of the U.S. automaker’s previously announced plan to move information technology work back into the company.

GM said it will hire the software developers, database experts, analysts and other IT positions over the next four years for the office in Warren, Michigan. It is the second of four software development centers GM plans to open, following one it announced last month in Austin, Texas.

In July, the Detroit automaker said it would reverse years of outsourcing IT work. GM now outsources about 90 percent of its IT services and provides the rest in-house, but it wants to flip those figures in the next three to five years.

The IT overhaul is spearheaded by GM Chief Information Officer Randy Mott, who outlined the plan to GM’s 1,500 IT employees in June. The former Hewlett-Packard Co executive believes the moves will make GM more efficient and productive.

GM, which has not disclosed the cost or savings of its strategy, plans to cut the automaker’s sprawling list of IT applications by at least 40 percent and move to a more standardized platform. GM will also simplify the way it transmits data.
