Toshiba Develops Mobile Sensor

Toshiba has created a new image sensor for mobile phones and tablets that promises better image resolution for run-of-the-mill smartphones when it goes into mass production.

The T4KA7 is a 1/2.4-inch, 20-megapixel backside illuminated sensor with a 1.12 micrometer pixel size, which provides for a smaller sensor size overall.

The sensor allows for a lower module height of under 6 millimeters compared to the current 20-megapixel, 1.2-micrometer sensors, the company said.

“T4KA7 is the first 1.12-micrometer, 20-megapixel sensor on the market with a high frame rate of 22 fps at full resolution,” a Toshiba spokeswoman wrote in an email.

The frame rate is 1.8 times the speed of Toshiba’s previous 20-megapixel sensor, the T4K46.

When zooming digitally, the sensor provides crisper images compared to 13- and 16-megapixel sensors, which are resolutions widely adopted in recent smartphones, she added.

Announced earlier this year, Samsung’s camera-phone hybrid Galaxy K zoomhas a 20.7-megapixel image sensor that is supposed to perform well when taking photos in low-light settings.

Without a specific measurement for comparison, it’s hard to say whether the T4KA7 would do any better in low-light shooting situations than other sensors, the Toshiba spokeswoman said.

“We think we are providing top-class sensors in terms of pixel performance,” she added.

Toshiba is producing samples of its new sensors now, with mass production of up to half a million units per month to begin in November.

Higher-end smartphones already featuring 20-megapixel cameras include the Sony Xperia Z1, the Nokia Lumia 930 and 1520.

Announced last month, the Nokia Lumia 1020 sports a camera designed for photographers — it has a sensor with 41-megapixel resolution.

Bitcoin Use Growing

Bitcoin is gaing greater acceptance at U.S. online merchants including Overstock.com and Expedia, as customers use a digital currency that just a few years ago was virtually unknown but is now showing some staying power.

Though sales paid for in bitcoin so far at vendors interviewed for this article have been a fraction of one percent, they expect that as acceptance grows, the online currency will one day be as ubiquitous as the internet.

“Bitcoin isn’t going anywhere; it’s here to stay,” said Michael Gulmann, vice president of global products at Expedia Inc. in Seattle, the largest online travel agent. “We want to be there from the beginning.” Expedia started accepting bitcoin payments for hotel bookings on July 11.

Until recently a niche alternative currency touted by a fervent group of followers, bitcoin has evolved into a software-based payment online system. Bitcoins are stored in a wallet with a unique identification number and companies like Coinbase and Blockchain can hold the currency for the user.

When buying an item from a merchant’s website, a customer simply clicks on the bitcoin option and a pop-in window appears where he can type in his wallet ID number.

Still, broad-based adoption of bitcoin is at least five years away because most consumers still prefer to use credit cards, analysts said.

“Bitcoin is a new way of making payments, but it’s not solving a problem that’s broken,” said George Peabody, payments consultant at Glenbrook Partners in Menlo Park, California. “Retail payments aren’t broken.”

There are also worries about bitcoin’s volatility: its price in U.S. dollars changes every day.

That risk is borne by the consumer and the bitcoin payment processor, such as Coinbase or Bitpay, not the retailer. The vendor doesn’t hold the bitcoin and is paid in U.S. dollars. As soon as a customer pays in bitcoin, the digital currency goes to the payment processor and the processor immediately pays the merchant, for a fee of less than 1 percent.

“We don’t have to deal with the actual holding of the bitcoin: it’s the payment processor that takes the currency risk for us,” said Bernie Han, chief operating officer at Dish Network Corp, in Englewood, Colorado. “That’s what makes it appealing for us and I guess for other merchants as well.”

Dell Goes Bitcoin

Want to purchase a laptop with bitcoins? Dell is now accepting the digital currency as a form of payment.

Consumer and business shoppers can pay for products directly via bitcoins or through Coinbase, a third-party payment processing company, Dell said.

Buyers can pay for products through Bitcoin wallets or by scanning a QR code with a smartphone.

The volatile Bitcoin has had its share of controversies and exchange shutdowns as the currency matures. Companies like Overstock.com, Newegg, Expedia and some Amazon storefronts accept Bitcoin as a form of payment. But major retailers like Walmart and eBay have not warmed up to the idea. The value of one bitcoin was around $630 as of Friday, according to multiple cryptocurrency website.

There are some advantages to paying via Bitcoin. The form of currency is accepted around the world, and for Dell, the payment-processing cost is less than with credit cards.

But the form of payment has its quirks.

“Due to the nature of the Bitcoin network, once you initiate a Bitcoin transaction you cannot change or cancel it,” Dell said on a terms and conditions page.

Customers could seek refunds in the case of canceled transactions or product returns.

“For a qualifying return of product paid for in Bitcoin, any refund due will be remitted to the purchaser via check in U.S. Dollars for the full amount of the purchase price paid at the time of the original transaction, less any applicable restocking fees,” Dell said.

Hackers Going After Traffic Signs

After hackers played several high-profile pranks with traffic signs, including warning San Francisco drivers of a Godzilla attack, the U.S. government advised operators of electronic highway signs to take “defensive measures” to better secure their property.

Last month, signs on San Francisco’s Van Ness Ave were photographed flashing “Godzilla Attack! Turn Back” and highway signs across North Carolina were tampered with last week to read “Hack by Sun Hacker.”

The Department of Homeland Security’s Industrial Control Systems Cyber Emergency Response Team, or ICS-CERT, this week advised cities, highway operators and other customers of digital-sign maker Daktronics Inc to take “defensive measures” to minimize the possibility of similar attacks.

It said that information had been posted on the Internet advising hackers how to access those systems using default passwords coded into the company’s software. “ICS-CERT recommends entities review sign messaging, update access credentials and harden communication paths to the signs,” the agency said in an alert posted on Thursday.

Jody Huntimer, a representative for Daktronics, declined to say if the recent attacks involved the bug reported by ICS-CERT.

“We are working with the ICS-CERT team to clarify the current alert and will release a statement once we have assessed the situation and developed customer recommendations,” Huntimer said via email.

Krebs on Security, a widely read security blog, posted a confidential report from the Center for Internet Strategy, or CIS, which was sent to state security officials. It warned that the pranks created a public safety risk because drivers often slow or stop to view the signs and take pictures.

CIS also predicated that amateur hackers might attempt to hack into other systems in the coming weeks following the May 27 release of “Watch Dogs,” a video game from Ubisoft focused on hacking critical infrastructure.

Venture Capaitalist Going Internet Again

Venture capitalists invested more money into Internet companies last year than they have since the dot-com bust, according to a survey published last Friday.

Internet companies in the U.S. took in $7.1 billion from VCs in 1,059 deals in 2013, the highest level of Internet investment in terms of dollars and deals since 2001, according to The MoneyTree Report by PricewaterhouseCoopers and the National Venture Capital Association, based on data from Thomson Reuters. In comparison, VC investment in Internet companies totaled $6.7 billion in 995 deals in 2012, another strong year, according to the MoneyTree report.

In addition, VCs invested $110 billion in 1,523 software industry deals last year, the highest level in both dollars and number of deals for the sector since 2000, according to the MoneyTree report. VC dollars going into software rose 27 percent year over year, while the number of deals increased 10 percent.

The amount of money invested in the software industry accounted for 37 percent of total VC investments in 2013, the highest percentage since the MoneyTree report was initiated in 1995.

All this is taking place against a backdrop of a generally strong VC environment, as VCs invested $29.4 billion in 3,995 deals across all sectors in 2013, a year-over-year increase of 7 percent in dollars and 4 percent in deals, according to the report.

Companies involved in big data, mobile apps, security, digital marketing, and medical and health software are among those that are especially interesting to VCs, according to Mark McCaffrey, PwC’s U.S. and global software leader.

Top deals in the fourth quarter of 2013 included a $225,000 investment in Pinterest, a site for sharing photos, recipes and other items of personal interest, and a $177,514 investment in Palantir Technologies, a government contractor in the systems integration business, according to MoneyTree data.

Going into 2014 a sense of optimism prevails, but this does not mean that the tech industry is going through a bubble of the sort that arose in 1999 and 2000, McCaffrey said.

3D Printer Goes Retail

MakerBot, a 3D printer maker which opened two new retail stores last week, is among the companies trying to bring the cutting-edge digital manufacturing technology to Main Street consumers, but skeptics say the debut may be premature.

MakerBot, a unit of Stratasys Ltd, opened retail stores this week in Boston and in Greenwich, Connecticut, both of which are twice the size of MakerBot’s first store, 1,500 square feet in downtown Manhattan.

The company offers designs for more than 100,000 items through its “Thingiverse” online user community. The products range from knick-knacks like zombie sculptures to jewelry, sink drains and even medical devices. They are printed using its line of corn-based plastic fibers in more than a dozen colors.

“For most people 3D printing is futuristic science fiction. We’re here to make it real,” said CEO Bre Pettis, who cut the ribbon at the store on Boston’s fashionable Newbury Street using scissors made on one of MakerBot’s Replicator printers which start at $2,199.

Pettis, who has purchased splashy magazine ads to promote 3D printers as holiday gifts, believes there could soon be a 3D printer on every block in America.

Yet some technology experts say 3D printers may not be ready for prime time because they are still much less user friendly than most modern consumer electronics.

“There is so much hype,” said Pete Basiliere, an analyst at technology research firm Gartner. “People are getting a little bit misled as to how easy it is,” he said.

Some investors also are skeptical of 3D printing’s readiness for the market. Short-seller Citron this week published an article questioning the earnings of Germany’s voxeljet AG’s, and shares in the sector fell, including those of MakerBot parent Stratasys and rivals 3D Systems Corp and ExOne Co.

Stanford Develops Carbon Nanotubes

Researchers at Stanford University have demonstrated the first functional computer constructed using only carbon nanotube transistors.

Scientists have been experimenting with transistors based on carbon nanotubes, or CNTs, as substitutes for silicon transistors, which may soon hit their physical limits.

The rudimentary CNT computer is said to run a simple operating system capable of multitasking, according to a synopsis of an article published in the journal Nature.

Made of 178 transistors, each containing between 10 and 200 carbon nanotubes, the computer can do four tasks summarized as instruction fetch, data fetch, arithmetic operation and write-back, and run two different programs concurrently.

The research team was led by Stanford professors Subhasish Mitra and H.S. Philip Wong.

“People have been talking about a new era of carbon nanotube electronics moving beyond silicon,” Mitra said in a statement. “But there have been few demonstrations of complete digital systems using [the] technology. Here is the proof.”

IBM last October said its scientists had placed more than 10,000 transistors made of nano-size tubes of carbon on a single chip. Previous efforts had yielded chips with just a few hundred carbon nanotubes.

HP Looks Beyond Windows

Hewlett-Packard has announced the availability of its latest Pavilion laptop with Google’s Chrome OS as the PC maker attempts to improve laptop sales by offering an alternative to the Windows OS.

The Pavilion 14 Chromebook has a 14-inch screen and runs on a dual-core Intel processor. The laptop is roughly 21 millimeters thick, and weighs 1.8 kilograms. It offers just over four hours of battery life, said David Conrad, director for product management at HP’s consumer products group.

The laptop is expected to ship on Monday in the U.S. starting at $329.99. The company did not immediately provide worldwide availability information.

HP wanted to widen its product offerings and the new Chromebook is targeted at those who do most of their computing on the Web, Conrad said.

“It’s really about choice. We have a very wide offering,” Conrad said. “We think the time is right for an additional choice for people to have a gateway to their Google digital lifestyle.”

The laptop has only 16GB of solid-state drive storage, but will offer 100GB of free Google Drive storage for two years.

The Chromebook has the same design as HP’s other PC offerings, which mostly run on Windows and have standard-capacity hard drives. But, with a lot of data moving to the cloud, the Chromebook provides a different usage model.

“We see this as another device to be used around the house. It’s easily managed,” Conrad said.

Intel Buys Patents

Intel on Monday spent US$375 million to purchase nearly 1,700 wireless networking patents from subsidiaries of digital communications company Interdigital.

Intel will get patents that cover a range of 3G, LTE and Wi-Fi technologies from Interdigital. The patents should boost Intel’s product mobile product portfolio as the company establishes a presence in the smartphone and tablet markets, which is currently ruled by ARM.

Intel has said it will integrate 3G and 4G LTE capabilities along with its Atom microprocessor in devices like smartphones and tablets. Intel made its first entry into the smartphone market earlier this year with its Atom chip code-named Medfield, which is being used in handsets from Lenovo, Orange and Lava International.

Intel later this year will release a dual-core Atom Z2580 processor with 3G, 4G and LTE capabilities. Intel’s upcoming Atom chip for tablets, code-named Clover Trail, will also come with mobile broadband options.

Intel started building its wireless business following the acquisition of Infineon Wireless for $1.4 billion, which was completed last year.

Wireless is a fast-changing market, and the company is making this investment to support the business, according to Chuck Mulloy, an Intel spokesman.

“This was an opportunity to add some value to our patent portfolio. That’s over and above what we have,” Mulloy said.

Yahoo Goes-DO NOT TRACK

Yahoo websites worldwide will comply with users “do not track” settings starting later this year, Yahoo announced Wednesday.

Most major browsers are now able to send a message to sites visited, indicating whether users want their surfing behavior to be tracked by cookies for the purposes of displaying personalized ads. In February the last major hold-out, Google, announced that its Chrome browser will include do-not-track support by the end of the year.

That message, an HTTP (hypertext transfer protocol) header accompanying a request to display a Web page, avoids the awkward paradox that to store a visitor’s preference not to be tracked by cookies, sites had to store a cookie containing that preference, and provides a consistent way to store and indicate such preferences across all Web sites that respect the do-not-track header.

Support for the do-not-track header has been in the works since last year, Yahoo said. All Yahoo sites will respect the header, including those of Right Media and Interclick, two Yahoo subsidiaries specializing in behavioral or data-driven advertising, the company said.

The company’s announcement comes the same day that the U.S. House of Representatives’ Subcommittee on Commerce, Manufacturing, and Trade is set to hold a hearing on balancing privacy and innovation, and in the same week that the U.S. Federal Trade Commission called for creation of a do-not-track tool for Internet users.

In a statement announcing its plans for allowing visitors to opt out of tracking, Yahoo maintained that allowing advertisers to regulate themselves was the best and quickest way to introduce protections to the market place without sacrificing innovation or value creation.
