Google Announces Project Ara Development Plans

As reported by The Guardian: Google announced its intention to move forward with the development of Project Ara, a $ 50 customizable module smartphone with interchangeable component blocks.

The concept is designed to give users unlimited ability to upgrade the device by swapping components. Despite its small staff size, the company’s Advanced Technology and Projects group (ATAP) is expected to have a working prototype within the next few weeks and will prepare a version for the consumer market for early 2015.

Project Ara was originally the brainchild of Motorola, whose parent company Google sold to Lenovo in January 2014. However, when the internet giant struck the Motorola deal with Lenovo, it retained the ambitious Ara project that was first announced by Motorola in Fall 2013. Project Ara will continue to be headed by ATAP, which is another Motorola-created company component that Google will retain post-sale.

The driving forces behind ATAP and Project Ara are Regina Dugan and Paul Eremenko, both of whom are veterans of the U.S. government’s Defense Advanced Research Projects Agency (DARPA). Ms. Dugan serves as head of ATAP, while Mr. Eremenko is the project head for Ara. The design of Project Ara is meant to be very user-friendly. It allows the user to upgrade a smartphone as easily as erecting a set of building blocks. For instance, if a user wanted a faster CPU or stronger battery, they could acquire the individual components and switch out old for new. Both developers and users would benefit from this platform that allows for tons of creative options. Many experts believe that if Project Ara lives up to its potential, it could become the Android of hardware by creating unlimited opportunities for developers and users to construct unique consumer modules.

Another feature of Project Ara that has Google very excited is the development of a new high-speed 3D printer that can manufacture modules in mass quantities. This new technology allows the smartphones to be mass-produced and customized in a way that is unheard of for any consumer product. Additionally, the technology could ultimately lead to the printing of electrical elements, such as antennas and adapters, as opposed to conventional manufactured means.


The platform of Ara will support three sizes of smartphone–mini, medium, and jumbo-sized.

Specific measurement information is being kept under wraps. However, Google has released some general details to whet consumer appetites. The mini will have a very compact build similar to a razor phone, the medium will follow a more mainstream design like the iPhone, and the jumbo will resemble a phablet (phone tablet) format. The size of each phone offered will depend on its endoskelton, which also serves as the one component of Ara that is Google-devised and branded. This component of Ara has an aluminum frame with a small amount of network circuitry so the modules can communicate and a tiny battery. Every component of Ara comes in the form of a module and slide into place to form the phone. The larger the size of the phone, the more modules it can contain. In the initial prototype, pins were used to connect the modules to the endoskelton. However, Google has plans later in the year to modify that aspect of Ara and utilize more space-saving, capacitive connections.

Additional development features of Project Ara that have the internet giant and public anxiously awaiting its consumer debut include the ability to hot-swap modules without powering down, interchange any individual components of similar size no matter its function, wi-fi connectivity, and of course, the exceptional value of $50 for the basic phone that users can customize to one’s specific needs and desires. Google could be on the brink of the next technological phenomenon and consumers will reap the benefits no matter what the outcome.

First Outdoor Flocks of Drones Demonstrated in the EU

As reported by The Physics arXiv: If you've ever watched huge flocks of starlings wheel and pulsate in the early evening sky, you’ll know how spectacular this phenomenon can be. Starlings probably flock to reduce their chances of attack by predators such as peregrine falcons.

But their are many other reasons why this kind of group behavior is useful—more effectively navigation and foraging, for example. So it’s no surprise that various teams want to reproduce the same kind of behavior in artificial systems.

That’s turned out to be harder than it sounds, particularly for aerial flocking. So while various groups have created semi-autonomous flocks, and one group created a flock of slow-moving blimps in a gymnasium, nobody has successfully demonstrated a fully autonomous flock of robotic flyers that can fly outdoors.

Until now. Today, Gabor Vásárhelyi and pals from Eötvös University in Budapest, Hungary, reveal that they have successfully demonstrated the first autonomous flying robots capable of flockin

g outdoors, just as starlings do.

Flocking is hard because of each member of the flock has to be able to sense its environment and respond to changes quickly and accurately. That means each flyer has to measure its own velocity and position, the position and velocity of those around it, and use this information to calculate what to do next.

Even then, it must be capable of carrying out the necessary flight adjustments quickly. These machines must be able to hover, to fly in a specific direction at a specific speed and to change tack rapidly.

And they must be able to do all this using their own own on-board decision making process.

That’s a big ask but it has looked increasingly possible in recent years given that stable flying machines such as helicopters and quadcopters are now commercially available.

Vásárhelyi start with a commercially available quadcopter known as the MK Basicset L4-ME from the German company MikroKopter. This is capable of self-stabilized flight and is controlled using a handheld remote.

An example of the navigation module used to help provide the
flocking, formation, target tracking, and obstacle avoidance features.

The team’s first step was to modify these machines to make them autonomous. They did this by attaching an extension board carrying a variety of navigational devices such as a gyroscope, accelerometer, GPS receiver and so on as well as a wireless communications unit and a minicomputer.

During flight, each flyer constantly broadcasts its position and velocity to the others which then determine their own actions using the team’s flocking algorithm. This essentially implements two rules, a short range repulsion that prevents adjacent flyers from colliding, and a rule that aligns their velocity and keeps adjacent flyers going in roughly the same direction at the same speed.

Simulation of actual data generated from target tracking exercises.

Two reduce the amount of calculating each flyer has to do, the quadcopters all fly at the same altitude so that the flocking problem becomes a 2 dimensional one.

There is also a ground-based PC monitoring what’s going on and this can make real time changes to the algorithms controlling each flyer. But crucially, the flock does not rely on any centralized control for its behavior.

The results are impressive. These guys have successfully flown flocks with up to ten quadcopters in the air simultaneously. “We successfully established the first decentralized, autonomous multi-copter flock in an outdoor environment, with swarms of up to 10 flying robots, flying stably for up to 20 minutes,” they say.

They also find a number of interesting behaviors. One of the key problems these guys have to handle is the inevitable delay each flyer experiences between receiving information, processing it and then performing the necessary changes in flight.

Target tracking a moving vehicle.

This kind of delay can lead to all kinds of interesting oscillations within the flock. But it can also destroy the flock if it gets out of control. So the flight algorithms must be carefully fine-tuned to damp out the destructive effects.

But with this in hand, Vásárhelyi and co say they were able to fly their copters in various formations such as ring shapes and in lines. They've also observed self-organised behavior in which the quadcopters fly in lines and circles within pre-determined boundaries, just as locusts do in a similar circumstances.

Obstruction avoidance simulation - the flock is attempting to
reach the large geofenced area, while staying out of the smaller
obstacle areas.

There are limits on the behavior of the flocks, of course. The speed of he flyers determines the required braking distance between them to prevent collisions. And in any case, the average distance between the flyers is between 6 and 10 meters. This is determined by the positional accuracy of the GPS sensors which is to within 2 meters or so. Tighter formations will require better positioning accuracy.

Nevertheless, this is an exciting first step in this area. The potential applications for flocks are numerous. The researchers imagine using them for large-scale, redundant observations over wide areas, perhaps for farming, traffic monitoring and, of course, military purposes. And equipped with sensors, flocks could monitor large volumes of the atmosphere for signs of pollution. A real advantage in all this is the redundancy that a flock offers if one unit malfunctions.

With the first success in outdoor autonomous flocks, it shouldn't be long before we see more of these in the real world. Perhaps one day we’ll even be able to watch them gather at dusk and demonstrate their own spectacular aerial displays.

California Court Rules Looking at Maps Apps Okay — But What About Everything Else?

As reported by Recode: A California appeals court today reversed a decision against a driver who was ticketed for looking at a map on his cell phone to find an alternate route around traffic.

The court found that the law prohibits listening and talking on the phone, as well as texting while driving, without using a hands-free device — but the law doesn't say anything that would ban looking at a map app.

Though it could still be appealed, the ruling is important given the broad popularity of mapping applications, whose main value is helping people navigate while they are with their phones, on the go.

What’s interesting is the decision specifically refers to the legality of the act of “looking at or checking a map.”

But c’mon — looking is not really all you do when you use Waze or Google Maps or your map application of choice. Rerouting around a traffic jam generally requires more than just a glance at your phone.
(Mapping apps do make some efforts around driver safety; for instance, Apple Maps takes over the lock screen during navigation, and Waze asks people in a moving vehicle to confirm they are a passenger before they are allowed to type. And all the apps can be controlled by voice. But still.)

While the court decision doesn't really address this particular point, it does refer to a 2012 clarification to the law that allowed drivers to “physically touch a speaker phone or other wireless communication device (e.g., Bluetooth speaker) to initiate or end contact with the other party.” The decision also notes that “surfing the Internet” from a phone while driving is not specifically banned.

But is it safe and should it be legal to touch the screen to open a maps app, pinch to zoom, and navigate to a menu that provides alternate routes? That seems slightly more important for the court and the law to clarify.

Uber Kept New Drivers Off The Road To Encourage Surge Pricing And Increase Fares

As reported by The Verge: Andrew Lane is a regular Uber customer with some fond memories of the service. Last year on President's Day he was the lucky rider selected for an "Ubercade" upgrade. "They sent over a free limo with secret service agents and everything. I got my girlfriend and we cruised by her ex-boyfriend's place. It was awesome." 

"We didn't activate new drivers to make earnings even higher this weekend." 

But this Valentines day, while traveling through San Diego in an Uber car, Lane heard something that disturbed him. "The driver had a Ford Sync system, and it read his text messages out loud." The message, which came wedged between numerous texts about a promotion for free roses, said, "UberX is very close to SURGE. It's Valentine's Day! People will be out all night and we didn't activate new drivers to make earnings even higher this weekend."

Uber’s surge pricing has been a controversial feature of the company’s business for some time. It uses an algorithm to raise and lower the price based on demand. At extremely busy times, especially holidays, rates can be as many as seven times the normal price. The company's CEO, Travis Kalanick, has been front and center defending this model.  

"Surge pricing only kicks in in order to maximize the number of trips that happen and therefore reduce the number of people that are stranded," he told Wired in an interview. Kalanick has always maintained that Uber is a neutral party, a technology platform that helps to most efficiently connect drivers and riders. "We are not setting the price. The market is setting the price. We have algorithms to determine what that market is."

"We are not setting the price. The market is setting the price." 

When Lane heard the Uber text message, he understood it to mean that the company was keeping current drivers off the road, limiting the supply to raise rates. To Lane it seemed Uber was favoring drivers over riders. "It made me angry, you know," says Lane. "Basically they are trying to rig the system to jack up fares on customers like me."

A law professor briefed on the text message says it may be suspect, given the company’s public framing of surge pricing. "This certainly sounds deceptive," says Arnold Rosenberg, assistant dean at the California Western School of Law in San Diego. "Something like this violates state laws around unfair business practices as well as Section 5 of the FTC act."

Uber says the whole thing is a misunderstanding.  Uber confirmed the text message, but says the whole thing is a misunderstanding. The company did not artificially restrict the number of drivers who were able to come on to the system on Valentine's Day — a particularly busy day for Uber rides — says spokesman Andrew Noyes. He explained the text simply noted that Uber did not onboard as many San Diego drivers as they could have that week because in the two weeks prior, a very large number of new drivers were added to the system. Earnings had been low, and the company wanted to reward new drivers with a strong holiday paycheck.

In other words, this wasn't Uber specifically tweaking the number of drivers at a given time to tip things over into a surge. It was a big-picture strategy to make their new drivers happy. Noyes points out that during the week of the 10th, when this trip took place, only 5.6 percent of the trips on the Uber network were affected by surge pricing.

"That is a slap in the face to customers." 

Regardless of when and why the additional drivers were withheld, the larger tension still stands: Uber insists that it's a marketplace, a neutral technology platform that works solely to connect drivers and riders with maximal efficiency. But it is also a business, and so may sometimes tilt the scales to keep drivers, its employees and contractors, happy.

The company’s explanation didn’t sit well with Lane. "Honestly it feels worse. Uber specifically withheld supply on a busy holiday weekend even while it predicted that doing so would create significantly higher prices," he said. "Best-case scenario it’s fleecing customers to enrich drivers, worst-case scenario it’s fleecing customers to enrich the broker (Uber). That is a slap in the face to customers."

Why You Could Soon Be Buying Your Electricity From Tesla

As reported by Quartz: Last week, it was argued that Tesla’s most disruptive product might not be its cars.  

Today, Morgan Stanley has provided further detail around this thesis, which is gaining increased traction on Wall Street. Tesla shares have soared about 13% this morning and are trading at fresh highs.

In a note published this morning, the investment bank posits that Elon Musk’s electric car company, which will unveil its plans to build  the world’s biggest lithium-ion battery pack facility this week, is poised to disrupt the $1.5 trillion electric utility industry. Tesla doesn't just make high-performance automobiles, Morgan Stanley analyst Adam Jonas argues, it’s also producing a mobile fleet of electrical grid storage.  The 40,000 Tesla vehicles already on the US roads contain about 3.3 gigawatts of storage capacity, roughly 0.3% of US electrical production capacity and 14% of US grid storage, he estimates.

By 2028, Morgan Stanley (which, it must be said, is among the most bullish of all Wall Street banks when it comes to the car company) estimates there will be 3.9 million Tesla vehicles on US roads. They will have a combined energy storage capacity of 237 gigawatts, some 22% of today’s US production capacity and nearly 10 times larger than all US grid storage that exists today.

Tesla’s “giga-factory,” where the lithium-ion battery packs will be produced, will probably cost $1 billion to build, Morgan Stanley estimates. But there will be myriad opportunities for the company to reap returns from that investment beyond sales of its own cars.

Plenty of questions remain about Telsa’s competency in the field of battery production and energy storage. At the moment, Tesla’s batteries are produced by Panasonic, which some expect to be a partner in the giga-factory.  At any rate it’s worth remembering that multiple battery fires last year sparked a federal probe into the company. (There were no injuries, and Musk has forcefully argued that there is “absolutely zero doubt that it is safer to power a car with a battery than a large tank of highly flammable liquid.”)  

Last week a Barron’s report  (paywall) said Tesla’s lofty valuation “exceeds fundamental reasoning.” But if Tesla really can become the world’s low-cost producer in energy storage, as Morgan Stanley predicts, then maybe it’s not so insane, after all. 

Rolls-Royce Is Developing Drone Cargo Ships

As reported by The Verge: Drones are already patrolling the skies, and eventually Rolls-Royce wants to see them take over the seas too. According to Bloomberg, Rolls-Royce Holdings is developing unmanned cargo ships that can be remotely controlled by captains using a virtual-reality recreation of a vessel's bridge. Development on the ships began last year, and it expects the unmanned ships to eventually offer a safer, cleaner, and less-expensive option for moving cargo.

"Now the technology is at the level where we can make this happen, and society is moving in this direction," Oskar Levander, a marine engineering and technology executive at Rolls-Royce, tells Bloomberg. "If we want marine to do this, now is the time to move."

While now may be Rolls-Royce's time to start moving, it's far from the time when these ships will set sail. As Bloomberg points out, there are quite a few regulatory and financial hurdles in the way of unmanned vessels, including international minimum crew requirements and an ineligibility for being insured by major providers. And, as when it comes to self-driving cars taking over the roads, there are already plenty of concerns about what could go wrong when humans are removed from the picture.

Levander acknowledges to Bloomberg that it won't be a quick transition, and he makes it clear that Rolls-Royce Holdings — the aircraft and ship engineering firm now separate from the BMW-owned automaker — is instead trying to get ahead of the pack. Its vision is appealing: by removing the crew, the bridge, and other equipment needed to support good living conditions, ships would reportedly be 5 percent lighter and burn 12 percent to 15 percent less fuel. Supporting the crew reportedly accounts for around 44 percent of total operating expenses on a large container ship as well, so there could eventually be an obvious path to savings.

Bloomberg reports that it could be a pricey path to get there though, as Rolls-Royce will have to develop new safety and backup equipment to handle potential machine failures. "It’s a given that the remote-controlled ship must be as safe as today," Levander tells Bloomberg. "But we actually think it can be even much safer than today." There's no word on how long development of the systems might take or what Rolls-Royce is doing to address its regulatory hurdles, but at least with self-driving cars, we've seen that lawmakers have been open to letting machine-controlled systems begin testing — so long as the right safety systems are in place.

Google Sets Roadblocks To Stop Distracted Driver Legislation

As reported by Reuters: Google is lobbying officials in at least three U.S. states to stop proposed restrictions on driving with headsets such as Google Glass, marking some of the first clashes over the nascent wearable technology.

Some eight U.S. states are considering regulation of Google Glass, a tiny computer screen mounted in the corner of an eyeglass frame. Law enforcement and other groups are concerned that drivers wearing the devices will pay more attention to their email than the road, causing serious accidents.

So-called wearables such as Google Glass, smart watches and sophisticated health devices may represent the next big shift in technology, just as smartphones evolved from personal computers, and enthusiasts predict billion-dollar markets. Google, which is still testing Glass, charges $1,500 per pair.

Google Inc has deployed lobbyists to persuade elected officials in Illinois, Delaware and Missouri that it is not necessary to restrict use of Google Glass behind the wheel, according to state lobbying disclosure records and interviews conducted by Reuters.

Legislators who introduced similar bills this year in three other states, New York, Maryland and West Virginia, say they have not yet been contacted by Google. Officials in New Jersey and Wyoming did not respond to inquiries from Reuters.

Courts are just beginning to consider the matter. Last month in San Diego, for instance, a woman's traffic ticket for wearing Google Glass behind the wheel was dismissed because there was no proof the device was operating at the time.

Google's main point to legislators is that regulation would be premature because Google Glass is not yet widely available, the state elected officials say.

Illinois state Senator Ira Silverstein, a Chicago Democrat who introduced a Google Glass restriction bill in December, responded that it was clear the merchandise was heading for the broader public. "Who are they fooling?"

Silverstein said he recently met with Google lobbyists trying to "kill" the bill, a position Silverstein suggested is driven by market considerations for the company.

State records show the month after Silverstein introduced his bill, Google retained John Borovicka, a former political director for President Obama's former chief of staff and current Chicago Mayor Rahm Emanuel. Borovicka visited Silverstein to lobby against the legislation, the state senator said.
Borovicka did not respond to a request for comment.

Asked about its lobbying efforts, Google said tech issues are a big part of current policy discussions in the states. "We think it is important to be part of those discussions," the company said in a statement.
Google has been scheduling Glass demonstrations across the country in an effort to educate the public on how the technology works.

"While Glass is currently in the hands of a small group of Explorers," the company said, "we find that when people try it for themselves they better understand the underlying principle that it's not meant to distract but rather connect people more with the world around them."

PERSUADING THE POWERFUL
Campaigns against distracted driving have gained significant traction in the United States. In 2012, over 3,000 people died due to crashes where texting or other activities were in play, according to Distraction.gov, a U.S. government web site devoted to the issue.

Delaware state Rep. Joseph Miro was one of the primary sponsors of a bill that banned texting while driving, and he also introduced legislation targeting Google Glass. So far, no states have passed Google Glass restrictions.

"I'm not against Google or Google Glass. It may have a place in society," said Miro, a Republican. "My issue is that while you are driving, you should have nothing that is going to impede the concentration of the driver."
According to Miro, a Google representative lobbied against the bill by forwarding a news article about the San Diego court case, as an attempt to show that the courts are taking a dim view towards prosecutions. His bill passed committee and could receive a floor vote this spring, Miro said.

Google's position is at odds with groups like the Delaware Developmental Disabilities Council, which in a letter last year said it supported restrictions on drivers' use of headsets such as Google Glass, believing it will lead to more accidents, causing more spinal cord and traumatic brain injuries.

Google advises people engaged in Glass field tests to abide by state laws that limit use of mobile devices while driving.

"Above all, even when you're following the law, don't hurt yourself or others by failing to pay attention to the road," the company said in guidance posted online.

Not all legislators pushing a Google Glass restriction have been visited by the company, however. In West Virginia, House of Delegates member Gary Howell, a Republican, said he has heard from out-of-state Google Glass users opposed to the bill but not from the company itself.

For Maryland House of Delegates member Benjamin Kramer, the San Diego traffic case shows a need for clear state laws. When a driver is pulled over, it will always be extremely difficult for law enforcement to prove whether Google Glass had been operating, said Kramer, a Democrat.
"The way to get around it is just to prohibit them altogether," he said.

Ford to Ditch Microsoft Sync Technology for BlackBerry QNX, Sources Say

As reported by the Seattle Times: Ford, struggling with in-car technology flaws, will base the next-generation Sync system on BlackBerry’s QNX and no longer use Microsoft’s Windows, according to people briefed on the matter.

Using QNX will be less expensive than licensing Microsoft technology and will improve the flexibility and speed of the next Sync system, said the sources, who asked not to be identified because the decision hasn’t been made public.

Ford has more than 7 million vehicles on the road with Sync using Microsoft voice-activated software to make mobile-phone calls and play music.

The switch may help Ford, the second-largest U.S. automaker, address customer complaints about malfunctioning technology systems and touch screens, which have hurt it in surveys by J.D. Power & Associates and Consumer Reports.

For BlackBerry, it’s a vote of support for a company that lost 95 percent of its value from mid-2008 to November and saw the collapse of a proposed $4.7 billion buyout.

“This would be a huge infusion of trust and confidence to have BlackBerry and QNX expanding into a Ford,” said Thilo Koslowski, auto analyst for researcher Gartner. “This is really the crown jewel in BlackBerry’s crown and could make the rest of the company shine as well.”

BlackBerry stock rose 6.6 percent Monday while Microsoft stock slipped 0.8 percent.

“We do not discuss details of our work with others or speculate on future products for competitive reasons,” Susannah Wesley, a Ford spokeswoman, wrote in an email. Spokesmen for Redmond-based Microsoft and QNX declined to comment.

Ford has said the quality of its vehicles has been “mixed” each of the past three years and fell short of its plan to improve those results in 2013. CEO Alan Mulally was said to be a candidate to become Microsoft’s chief until early this year.

Improving Sync is crucial for Ford to draw car shoppers who are increasingly looking to be connected at all times.

In-vehicle technology is the top selling point for 39 percent of auto buyers, more than twice the 14 percent who say their first consideration is traditional performance measures such as power and speed, according to a study by the consulting firm Accenture released in December.

Ford and Lincoln ranked Nos. 26 and 27 out of 28 brands in Consumer Reports’ annual auto-reliability survey released in October.

While the Lincoln luxury line matched the industry average in J.D. Power’s Initial Quality study in June, the namesake finished 27th out of 33 brands.

Technology companies are competing to win business from automakers as in-car technology becomes an increasingly important selling point.

Google announced an alliance with General Motors, Honda, Hyundai and chipmaker Nvidia in January to bring the Android operating system to cars. Apple is working with BMW, Mercedes-Benz, Nissan and others to introduce its iOS operating system to cars with devices such as the iPhone.

BlackBerry’s QNX Software Systems can be found in cars made by Volkswagen’s Audi unit and BMW, according to its website. QNX and Microsoft are the main suppliers of automotive operating-system software, according to researcher IHS iSuppli.

The switch would be a significant blow to Microsoft’s automotive-software business because Ford is by far its biggest customer, said Gartner’s Koslowski. Microsoft also has software in Kia Motors, Fiat models, Nissan and BMW models, according to its website.

Getting into the Ford system will expand QNX’s industry-leading position for automotive entertainment operating systems, which Koslowski said he estimates is as high as 70 percent.

QNX has done a better job of integrating compatibility with other operating systems, Koslowski said.

“The industry is realizing it has to do a better job to create a unique experience for its customers,” he said.

SpaceX Falcon Rocket to Test Landing Legs

As reported by Discovery News: Space Exploration Technologies is installing landing legs on its next Falcon 9 rocket, part of an ongoing quest to develop boosters that fly themselves back to the launch site for reuse.

This time, however, SpaceX hopes to cushion the rocket’s destructive impact into the Atlantic Ocean by restarting the Falcon 9’s engine and extending landing legs that will be attached to the booster’s aft section. The goal is a soft touchdown on the water.

Falcon 9 “will continue to land in the ocean until we prove precision control” from hypersonic all the way through subsonic regimes, SpaceX founder, chief executive and design engineer Elon Musk said on Twitter.  

SpaceX has been chipping away at that challenge in a related series of technology development initiatives.

In October 2013, SpaceX completed a program called Grasshopper to develop precision landing techniques. From a launch pad in McGregor, Texas, SpaceX flew a 10-story, first-stage Falcon rocket that ultimately reached an altitude of .46 miles (744 meters) before touching back down.

An expanded program is due to begin this year from a new test site at Spaceport America in New Mexico. The new prototype, known as Falcon 9R, will be outfitted with nine Merlin 1D engines, rather than just the single motor flown on Grasshopper, to reach higher altitudes and faster descent rates.

Next month’s test will be SpaceX’s second using an operational rocket.

The company’s September 2013 debut of its upgraded Falcon 9 rocket (flying for the first time from California) included a restart of the spent first-stage to slow the rocket’s descent.

The first of two planned engine restarts was successful. The second one failed because the rocket was spinning. Centrifugal force cut off the flow of fuel.

Musk said afterward that landing legs should help stabilize the rocket.

Four legs, which are made of carbon fiber with aluminum honeycomb, will be placed symmetrically around the base of the rocket. They will be stowed along the side of the vehicle during launch and extended down and outward for landing, SpaceX’s website shows.

Musk said the legs used for next month’s test will have a span of about 60 feet.

"Given all the things that would have to go right, the probability of recovering the first stage is low ... but we’re getting closer," SpaceX spokeswoman Emily Shanklin wrote in an email to Discovery News.

The Falcon 9 rocket due to fly on March 16 will be carrying a Dragon cargo capsule for the International Space Station. The mission is the third of 12 under SpaceX’s $1.6 billion contract with NASA.

The company, based in Hawthorne, Calif., also is working on version of Dragon to fly people.

A Plan to Lower Speed Camera Error Rates By Reversing the Incentives

As reported by The Atlantic Cities: Baltimore's particular speed camera problem first came to light in 2012, when the Baltimore Sun revealed that at least seven of the city's 83 radar cameras, all of them owned and operated by Xerox State and Local Solutions, were prone to issuing fines to drivers who were not exceeding the speed limit. Xerox itself claimed it found only five cameras that didn't work, and shut them down. The city, meanwhile, downplayed the problem even further, claiming the error rate for Xerox speed cameras was "one-quarter of one percent." In short: Nothing to see here!

Xerox's contract with Baltimore ended in 2012, but the deal is making headlines again thanks to a recent audit showing the company's cameras performed worse than even the Sun realized. The big takeaway? That error rate of "one-quarter of one percent"—promoted by city officials!—was actually upwards of 10 percent; 26 percent of issued citations were "questionable." 

The Sun, which first reported on the leaked audit last month, explains the ramifications: "The city issued roughly 700,000 speed camera tickets at $40 each in fiscal year 2012. If 10 percent were wrong, 70,000 would have wrongly been charged $2.8 million." And that's the low-end projection for how much Baltimore and Xerox may have bilked from citizens. 

But wait, it gets worse. The administration has also refused a request from the city council to officially release the audit, conducted by URS Corp. at a cost of $278,000, because doing so would violate a contract with Xerox that prohibits Baltimore from "referring or relating to, or reflecting, each party's internal considerations, discussions, analyses, and/or evaluations of issues raised during the settlement discussions."

Baltimore's speed camera fiasco does at least have something resembling a silver lining. In December 2013, the city announced it would no longer engage in revenue sharing with traffic camera vendors—a practice that Maryland Governor Martin O'Malley has decried as a "bounty" system. While Xerox got a cut of each fine its cameras issued, the decision actually resulted fromproblem cameras owned and operated by Brekford, the company Baltimore brought in to replace Xerox. 

But Maryland legislators aren't content to see Baltimore simply abandon the bounty system (which is supposedly illegal under state law anyway). They want to completely flip the incentives for camera operators: instead of paying companies for each citation they issue, pending legislation would require operators to be fined $1,000 every time they issue a citation in error. "This gives the vendors great incentive to make sure that they have done their homework," says Baltimore County Delegate Jon Cardin, the bill's sponsor.

You'd have to build a fine like that into any vendor contract, which could scare away companies (Xerox, Brekford) that have histories of fleecing drivers. A flat fee to vendors combined with penalties for faulty citations might even mean cities would be unable to find a company to operate speed cameras. Considering that traffic cameras are mostly for revenue generation (despite promising that the Xerox contract would reduce speeding in Baltimore, the annual haul from the cameras increased every year), that probably wouldn't be a bad thing. But insofar as there's a case for speed cameras, eradicating the incentive to wrongly ticket good drivers should clearly be part of it.

Combining low power consumption with high-sensitivity, high jamming immunity and concurrent GNSS operation (GPS/GLONASS, GPS/BeiDou, or GLONASS/BeiDou) the surface-mount CAM-M8Q is truly a drop-in solution for reliable and accurate satellite positioning anywhere in the world.

“Our CAM-M8Q is perfect for customers designing highly compact products who want to speed up product development while freeing resources for core activities,” explains Thomas Nigg, VP Product Marketing at u-blox.

CAM-M8Q is ideal for a wide range of applications such as personal locators, handheld navigators, wearable electronics as well as vehicle telematics systems used for emergency call, anti-theft, insurance and road pricing. Consistent omnidirectional antenna performance insures excellent performance regardless of module orientation.

It also has a feature whereby the internal chip antenna can be used as a backup antenna if the design makes use of an external antenna. This is an important feature for applications where there is a risk that the primary external antenna may malfunction or suffer damage, for example in vehicle tracking systems where damage to the external antenna is possible.

The module uses the latest u-blox M8 GNSS receiver chip qualified according to AEC-Q100 and is manufactured in ISO/TS 16949 certified sites. Qualification tests are performed as stipulated in the ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”.

The CAM M8Q is form-factor compatible to predecessor modules UC530 and UC530M, allowing the upgrade of existing designs with minimal effort.

Now, if we can get ublox to add in an integrated eLORAN receiver, and MEMS (micro-mechanical sensors that include an accelerometer and gyroscope for short term inertial navigation) - we'd have a nearly perfect tracking product - potentially with jamming detection.  They already have the MEMS interface available in a different module (the 3D ADR), so they are very close to reaching navigation nirvana.

LEAP: Microsoft Tries To Re-Invent GPS With Cloud-Based Processing

As reported by The Register: Microsoft has released a tool that it hopes will make it possible to add location-sensing abilities to many more devices.

The Microsoft Cloud-Offloaded GPS Experimental Kit is part of an effort to gather location data from GPS satellites without using much power. That's important because, as Microsoft explains, few applications drain a mobile device's battery more rapidly than contacting satellites. Redmond therefore wonders what might happen if devices “log just enough raw GPS signal for postprocessing” in the cloud, instead of doing everything on the mobile device itself.

Microsoft’s even cooked up a cloud service, dubbed Low Energy Assisted Positioning (LEAP), to do that work. In this paper, the researchers explain it works as follows:  “The GPS receiver only needs to be on for less than a second to collect the submillisecond level propagation delay for each satellite's signal.

With a reference to a nearby object, such as a cell tower, the LEAP server can infer the rest of the information necessary to perform GPS position calculation.”

Microsoft's also created hardware to help the experiment along. Detailed here and dubbed CLEO, the device comprises a GPS receiver, battery and SD card slot. “Compared to more than 30 seconds of heavy signal processing on standalone GPS receivers, we can achieve three orders of magnitude lower energy consumption per location tagging,” Microsoft says.

CLEO devices cannot go online: users must gather their SD cards to upload data into a PC. But there's nothing to stop a CLEO being attached to something moving, where it will presumably last longer than conventional location-tracking devices thanks to its skimpy data-generating design.

At a time when plenty of apps offer real-time data acquisition and processing, this experiment may not seem particularly sophisticated. But with a bit more polish applied, Microsoft could conceivably find itself with a very handy addition to mobile device operating systems. And with a little lateral thinking it could find itself with a very interesting device and service combination to fuel its aim of becoming a devices and services company.

One small wrinkle suggests itself: Google got itself into an awful lot of trouble by geolocating WiFi modems. Material about this project mentions using known pieces of infrastructure like cell towers to assist the location process, but neglects to say how Redmond came by or intends to source that data. Surely Microsoft won't go where even Google now fears to tread?

New, Inexpensive Solar Materials Boost Promise Of Hydrogen Fuel

As reported by the University of Wisconsin-Madison News: Generating electricity is not the only way to turn sunlight into energy we can use on demand. The sun can also drive reactions to create chemical fuels, such as hydrogen, that can in turn power cars, trucks and trains.

The trouble with solar fuel production is the cost of producing the sun-capturing semiconductors and the catalysts to generate fuel. The most efficient materials are far too expensive to produce fuel at a price that can compete with gasoline.

"In order to make commercially viable devices for solar fuel production, the material and the processing costs should be reduced significantly while achieving a high solar-to-fuel conversion efficiency," says Kyoung-Shin Choi, a chemistry professor at the University of Wisconsin-Madison.

In a study published last week in the journal Science, Choi and postdoctoral researcher Tae Woo Kim combined cheap, oxide-based materials to split water into hydrogen and oxygen gases using solar energy with a solar-to-hydrogen conversion efficiency of 1.7 percent, the highest reported for any oxide-based photoelectrode system.

Choi created solar cells from bismuth vanadate using electrodeposition — the same process employed to make gold-plated jewelry or surface-coat car bodies — to boost the compound's surface area to a remarkable 32 square meters for each gram.

"Without fancy equipment, high temperature or high pressure, we made a nanoporous semiconductor of very tiny particles that have a high surface area," says Choi, whose work is supported by the National Science Foundation. "More surface area means more contact area with water, and, therefore, more efficient water splitting."

Bismuth vanadate needs a hand in speeding the reaction that produces fuel, and that's where the paired catalysts come in.

While there are many research groups working on the development of photoelectric semiconductors, and many working on the development of water-splitting catalysts, according to Choi, the semiconductor-catalyst junction gets relatively little attention.

"The problem is, in the end you have to put them together," she says. "Even if you have the best semiconductor in the world and the best catalyst in the world, their overall efficiency can be limited by the semiconductor-catalyst interface."

“Without fancy equipment, high temperature or high pressure, we made a nanoporous semiconductor of very tiny particles that have a high surface area.”

Choi and Kim exploited a pair of cheap and somewhat flawed catalysts — iron oxide and nickel oxide — by stacking them on the bismuth vanadate to take advantage of their relative strengths.

"Since no one catalyst can make a good interface with both the semiconductor and the water that is our reactant, we choose to split that work into two parts," Choi says. "The iron oxide makes a good junction with bismuth vanadate, and the nickel oxide makes a good catalytic interface with water. So we use them together."

The dual-layer catalyst design enabled simultaneous optimization of semiconductor-catalyst junction and catalyst-water junction.

"Combining this cheap catalyst duo with our nanoporous high surface area semiconductor electrode resulted in the construction of an inexpensive all oxide-based photoelectrode system with a record high efficiency," Choi says.

She expects the basic work done to prove the efficiency enhancement by nanoporous bismuth vanadate electrode and dual catalyst layers will provide labs around the world with fodder for leaps forward.

"Other researchers studying different types of semiconductors or different types of catalysts can start to use this approach to identify which combinations of materials can be even more efficient," says Choi, whose lab is already tweaking their design. "Which some engineering, the efficiency we achieved could be further improved very fast."
