A flexible memristor has been developed by the U.S. National Institute of Standards and Technology, opening the door to new memory technologies.

It is the first time this kind of memory device, demonstrated for the first time last year, has been shown in flexible form.

The memristor (from "memory resistor") was made by setting titanium oxide, one of the common ingredients of sunscreen and toothpaste, onto flexible transparent polymer sheets, NIST announced Tuesday. By adding electrical contacts the NIST research team created a flexible memory switch that operates on fewer than 10 volts, maintains its memory when power is lost, and still functions after being flexed more than 4,000 times.

"We wanted to make a flexible memory component that would advance the development and metrology (the science of measurement) of flexible electronics, while being economical enough for widespread use," said Nist researcher Nadine Gergel-Hackett, in a statement. "Because the active component of our device can be fabricated from a liquid, there is the potential that in the future we can print the entire memory device as simply and inexpensively as we now print a slide on an overhead transparency."

The NIST research team created the memristor using an inexpensive setting technique, by spinning the titanium oxide in "sol gel" liquid form, depositing it on the transparent sheet, and then letting it dry on the polymer at room temperature. In a paper entitled "A Flexible Solution-Processed Memristor," the researchers noted that the memristor remained non-volatile for 14 days.

Memristors, which were hypothesized in the 1970s but only realized by Hewlett-Packard researchers in 2008, retain memory states when there is no electrical current being passed through them. A memristor has resistance to an electrical current, but that resistance changes depending on the amount of current and direction of the current flow. For a memory circuit, the current is passed one way for a zero, the other for a one, leaving the memristor in a high or low conductivity state. Resistance can then be read back later--in the case of the NIST memristor, for at least 14 days.

A flexible memristor would allow for the development of flexible chips that could be used in a variety of technologies, including for medical uses such as heart-rate or blood-sugar monitoring, said the NIST statement.

Wind River buy makes Intel a software company

Thousands of Intel employees already work on software, but with Intel's agreement to acquire Wind River Systems, the chipmaker is moving software from an indirect supporting role to a significant and direct revenue stream.

Intel's primary business is developing, manufacturing, and selling microprocessors, but software has gradually been rising in prominence. Starting years ago from only basic ingredients such as programming utilities, Intel has been gradually expanding its software work, for example by pushing the Moblin mobile Linux project and bulking up its Software and Services Group through a spending spree for smaller companies such as videogame physics engine maker Havok.

Wind River Systems' stock surged Thursday on news of Intel's $884 million agreement.

But Intel's agreement to acquire embedded computing specialist Wind River for $884 million in cash, announced Thursday and expected to close this summer, is on an entirely different scale. Wind River offers multiple operating systems and developer tools designed to be embedded in a multitude of products such as cars, printers, networking equipment, and phones. It's got a solid list of customers including Sony, Verizon, Boeing, and BMW; employs more than 1,600 people; and reported revenue of $359.7 million for its fiscal year that ended in January.

"It was a natural marriage," John Bruggeman, Wind River's chief marketing officer, said of the acquisition agreement. "You had a software leader looking to scale, and you had a bigger company looking to build a software franchise."

The proposed acquisition stops short of making Intel a head-on competitor with one of its biggest allies, Microsoft, because Wind River's operating system--a version of open-source Linux and its proprietary VxWorks--aren't aimed at PCs. But just as the arrival of Linux helped limit Windows' growth on servers, Intel's acquisition of Wind River could hurt Microsoft's ambitions for products such as Windows Mobile and Windows Embedded. Wind River supports not just Moblin but also Google's Linux-based Android operating system for mobile phones.

Microsoft isn't the only partner whose turf Intel would be edging onto with Wind River. Apple, which uses Intel chips in desktop and laptop computers, has its own iPhone business to promote.

Spending spree
Clearly, Intel hopes to benefit from software skills and products. Among its acquisitions in recent years are Neoptica for visual computing, OpenedHand for Linux user interface expertise, Swiftfoot Graphics for graphical rendering technology, Sarvega for XML processing, Elbrus/Unipro for Java and compiler tools, and Offset for visual computing. The general trend: Intel wants to supply its customers with more than just pieces of complicated silicon.

"We think this acquisition of Wind River is, potentially, a first step in Intel diversifying its business model towards that of IBM, a company that sells hardware, chips, software, and services worldwide," wrote Friedman, Billings, Ramsey Group analysts Craig Berger and Robert Pikover in a research note Thursday. "If Intel is beginning to diversify its business away from just semiconductors, we would expect a host of similar software- or services-related acquisitions in coming years."

Wind River's brand will live on at Intel, but the acquisition will mark the end of the independent history of an embedded computing player that's survived tough times and many market changes since its 1981 founding. Investors weren't sentimental, though: the company's stock jumped from about $8 per share to more than $11.50 in trading Thursday.

"We expect minimal changes to the business functions and organizational structure since we'll be a wholly owned subsidiary maintaining our current business model, brand, and product portfolio," but there will be some layoffs from redundancies, Wind River spokesman Bryan Thomas said.

Intel's name could give Wind River more clout in its own business transformation toward Linux. After a period of fighting Linux, the company has been trying in more recent years to embrace it, and it currently accounts for about 20 percent of the company's revenue compared to 80 percent for the VxWorks "legacy" business, Bruggeman said. Intel has for years been a serious Linux supporter, and the combination of the companies would bring more heft to the work.

"If you get on flight today or tomorrow, it's very, very likely the navigation system, landing sytem, autopilot system...is based on our software. If you're driving a car, our software was used in the car or the robot that produced that car."
--John Bruggeman, chief marketing officer, Wind River

Atom power
It's not all about software, of course.

Intel is best known for selling CPUs under brand names such as Pentium, Xeon, and Core, but it's also trying to get its newer Atom processor familyto catch on in embedded computing. Today, that market is dominated by ARM and PowerPC chips, and Wind River not only has a long list of potential customers, but also programming tools that could help them use Atom.

In a May meeting, Doug Davis, general manager of Intel's Embedded and Communications Group, said that embedded computing is a multibillion-dollar growth opportunity.

"This will let us do it a lot faster if we can get the software expertise along with the Atom processor to hit some of these markets," said Intel spokesman Bill Kircos. "Everything is becoming more computerlike and more Internet-savvy. That's the growth we're trying to aim for."

Here, Wind River's customer base will come in handy.

"Any phone call made any time anywhere to any place crosses our software somewhere along the route," Bruggeman said. "If you get on flight today or tomorrow, it's very, very likely the navigation system, landing sytem, autopilot system...is based on our software. If you're driving a car, our software was used in the car or the robot that produced that car."

No promise of success
Of course, Intel's power and technology doesn't guarantee success in entering new markets. The company largely withdrew from an attempt expand into communications and networking technology, for example, and it sold an embedded computing processor family, XScale, in 2006.

What makes Atom different from XScale is that Atom uses the x86 instruction set found in Intel's core product lines. That means much of the software and software technology from the PC market carries over to embedded computing. Intel hopes to spread x86 from high-end servers to mobile phones, but for the latter category must reckon with chips using ARM's architecture that are built by Motorola, Qualcomm, Samsung, and others.

Right now, Atom is the challenger to the ARM and PowerPC incumbent chip families in embedded computing, Bruggeman said, and Wind River as a part of Intel won't drop its existing work with those other chip families.

"This move was about creating a software franchise in the embedded and mobile space. If you're going to create a franchise in this space, you have to support multiple architectures," Bruggeman said, noting that Wind River will report not to a hardware executive but to Renee James, general manager of Intel's Software and Services Group.

"Intel's traditional embedded business (based on legacy Pentium processors) already generates more than $1 billion in annual revenues. Further, Intel said it has 300 embedded design wins and 1500 design engagements with the eight Atom-based embedded SOCs it has under development," Berger and Pikover wrote.

But that doesn't guarantee Intel success, they said. Intel's embedded computing strategy is "somewhat of a 'show-me' story given the firm's many largely unsuccessful attempts at growing various chip businesses outside of its core processor and chipset markets."

Adding a serious software portfolio, though, dramatically changes Intel's approach to embedded computing. Not only does Intel get a new revenue stream, new expertise, new customers, and new sales and support staff, it gets an opportunity for much fuller relationships with customers. Selling a company a chip is one thing, but selling them a chip, an operating system, and the developer tools to make a product work requires much closer and deeper ties.

Intel is betting on Moore's Law carrying computing to many, many more devices. It's not clear what share of Intel's PC and server dominance will carry over to an embedded computing market fragmented among many players and do-it-yourselfers. But with Wind River in house, Intel is in a much stronger position lead a wave of consolidation.

Paltalk says it has settled suit with Microsoft

Group messaging company Paltalk said on Thursday that it has reached a deal with Microsoft to settle a patent dispute.

As part of the deal, Microsoft has taken a license to Paltalk's patents and is paying an undisclosed amount of money, Paltalk said in a press release.

"After litigating with Microsoft for over two years to protect our intellectual property, it is gratifying to resolve this matter with Microsoft taking a license to Paltalk's patents," said Jason Katz, founder and CEO of Paltalk.

Paltalk filed its suit against Microsoft in September 2006, alleging that Halo 2 and Halo 3 running on Xbox Live violated Paltalk's patents. Paltalk said the case involved two patents that were originally filed in 1996 by MPath Interactive and acquired by Paltalk in 2001.

The case against Microsoft went to trial in March, Paltalk said, with a settlement reached on the fourth day of the case.

Microsoft declined to comment on the settlement. However, a source close to the company said the settlement was approved by the court last month.

Sony joins YouTube and Universal on Vevo video site.

Universal Music Group and YouTube have answered the question of whether any of the major labels will be interested in joining the new all music video Web site, Vevo.

Sony Music Entertainment has joined the venture, the companies said Thursday in a statement. Vevo will launch sometime later this year featuring video content from at least the two largest recording companies. (Universal is the largest.)

Some of the acts represented by the two labels include Amy Winehouse, U2, Bruce Springsteen, Duffy, Alicia Keys, Beyonce, Eminem, AC/DC, Kelly Clarkson, Lady Gaga, Carrie Underwood, Mariah Carey, Akon, The Killers, Mary J Blige, Black Eyed Peas, and Justin Timberlake.

Warner Music and EMI have yet to sign up, but music industry sources say that talks between the companies continue. Vevo is the brainchild of Universal Music CEO Doug Morris, who has long dreamed of a standalone video site where his artists' music videos would be the marquee product.

MTV turned music videos, which were once considered little more than a promotional tool for the labels, into a gold mine 30 years ago. Since then, music videos are far and away the most popular content on YouTube.

Vevo will not only feature traditional music videos, but possibly also present reality shows, video blogs, and other content built around artists. Universal said in the statement that it is also looking for outside investors.

While the labels will supply the content for Vevo, YouTube will look after all the back-end chores. Vevo will likely name former Universal Music exec Rio Caraeffas president.

Universal Music CEO Doug Morris partnered with Google's Eric Schmidt on Vevo. Now Sony Music Entertainment is joining the venture.

Pre vs. iPhone: Which offers the better value?

The Palm Pre's slick new software and cool design may make it the first true iPhone challenger on the market, but the competitively priced service plans from Sprint Nextel make the device an even more compelling alternative for frugal cellphone subscribers.

In terms of features, the Pre matches the iPhone on most bells and whistles . And it even has a few new capabilities not seen on the iPhone, such as an actual QWERTY keypad and the ability to have multiple applications open at once.

But for financially savvy shoppers, the Pre on Sprint's 3G network offers a value proposition that may just be enough to tip the scale when deciding between smartphones.

In terms of the upfront cost of the devices, the iPhone and the Pre are the same. The 8GB iPhone 3G costs $200, and so does the Pre with a $100 mail-in rebate. But it's really the service contract from Sprint that sets the Pre apart from the iPhone from a cost perspective.

"Feature for feature these phones are very comparable," said Peter Pham, CEO of Billshrink.com, a Web site that helps consumers cut waste out of their monthly bills. "But when you look at the total cost of ownership, the Pre on Sprint's network offers better value for many consumers."

Here's a breakdown comparing the two service plans:

Palm Pre (Sprint)

• $200: cost of phone with $100 rebate
• $70 per month: 450 voice minutes with unlimited messaging and data
• $90 per month: 900 voice minutes, unlimited messaging and data
• $100 per month: Unlimited voice minutes, messaging and data

iPhone (AT&T)

• $200: cost of phone
• $90 per month: 450 voice minutes, unlimited messaging and data
• $110 per month: 900 voice minute, unlimited messaging and data
• $150 per month: Unlimited voice minutes, messaging and data

The iPhone and the Pre each require a two-year contract. This means a power user, who subscribes to an unlimited everything plan would pay $3,600 before taxes and fees for the iPhone on AT&T's network. The same customer, getting a comparable service from Sprint, would pay $2,400 before taxes and fees. Over the two-year contract period, the Sprint Pre customer will save a total of $1,200.

While it seems pretty clear that the Pre from Sprint offers a better value, Pham said many consumers don't look at the total cost of ownership when shopping for a new phone and are often surprised down the road when they look at their phone bills.

"Most people don't realize how much they are paying for their service until they are about six to seven months into their two-year contracts," he said. "And then they start to realize that their bills are really high."

Pham also said most cell phone subscribers overpay for their service.

"I would say that eight out of 10 cell phone users are overpaying for the service they use each month," he said.

He suggests consumers use a tool on billshrink.com that analyzes cell phone bills to see when the most calls are made and to whom. The tool provides a summary showing consumers how many of their calls are free calls made to other people using the same cell phone network or calls made during nights and weekends. The tool also offers suggestions for new service plans that better fit the consumer's needs.

It will be interesting to see if Sprint's lower cost plans tips the scale for potential Pre customers. If it does, it will also be interesting to see if AT&T and other carriers, such as Verizon Wireless, which is also expected to get the Pre, will lower their prices to compete.

Microsoft gives Bing stronger search filter option

Microsoft has tweaked the search filters on its new Bing search engine following criticism that its smart motion video feature allowed Web surfers to watch porn without visiting adult Web sites.

The company announced the change in a blog post Thursday, as it also defended its approach to adult content in search results as a "more conservative approach than others in the industry." Bing does not show any video results for queries such as "porn" until the searcher disables a safe search filter, but following that click searchers can watch a small clip of adult content in the browser while still on the Bing site.

Bing's video preview feature--known as smart motion preview--is one of the selling points Microsoft has used to try to get momentum behind its revamped search engine. But the company acknowledged that corporate customers had expressed a desire to enforce stronger search filters within their networks, and so it is giving those network administrators as well as individual users on a home network the ability to add a string of text to Bing queries that automatically enforces the strictest search settings regardless of the user's individual setting.

This is "a short-term workaround" that will be finalized later, according to Microsoft, but no further details were provided. A Microsoft representative was looking into the details of how home users could implement this on their own networks.
