Sharp Shows MEMs

Sharp on Monday unveiled its latest prototypes of a new kind of display screen that it says brings several advantages over today’s liquid crystal display (LCD) screens.

The screens, called microelectromechanical systems (MEMS) displays for the tiny moving parts they contain, are being developed by the Japanese company in partnership with Qualcomm and were on show at the Ceatec electronics show just outside of Tokyo.

Behind each pixel in a MEMS display is a backlight that flashes red, green and blue in fast succession, and in front of it is a tiny shutter can be opened to let light through.

Synchronized to the backlight, the shutter can control the amount of each color of light allowed through. The eye perceives these flashes as the desired hue.

In contrast, today’s LCD screens create colored pixels using three filters. The filters swallow about two thirds of the brightness of the backlight before it leaves the display, said Akira Imai, deputy general manager of Sharp’s new business development center.

The MEMS display can allow all the light through, so the intensity of the backlight can be reduced using less power for the display, said Imai.

In a portable gadget, the screen often consumes more power than any other component, so reducing its demands can have a big impact on battery life.

The screens on show at Ceatec were 7-inch models with 800 pixel by 1,280 pixel resolution. The colors were bright and the screen image was sharp, although people viewing the screens did tend to see a brief flash of red, green and blue pixel each time they turned their eyes away from the display. That’s something Sharp is working on, said Imai.

Sharp also showed a version of the screen working in several low power modes.

The development work with Qualcomm began earlier this year when the U.S. company said it would invest $120 million into Sharp. The money, which was invested in two parts, was accompanied by Qualcomm’s MEMS expertise. Sharp has a long history in flat-panel display technology, especially LCD, and has recently been working on a new type of display called IGZO, on which the MEMS display is partly based.

Does Intel Need Help?

As time runs out for Intel to bring its Internet-based TV service by the end of the year, the outfit has approached Samsung and Amazon to ask them to lend a hand. Intel has asked about providing funding and distribution for the service. It looks like the set-top box project could be scrapped if a strategic partner isn’t found soon.

OnCue was supposed to allow users to watch live TV, on demand, and other offerings. Intel said it would provide the hardware and services directly to consumers and that the box would come with a camera that can detect who is in front of the TV. More than 300 engineers are working on the project under Erik Huggers, the head of Intel Media. A version of the service running on Intel hardware is testing with 3,000 Intel employees. Goodness knows what content they are running. Intel is having difficulty getting content deals.

Intel has yet to announce any TV programming partners, and Time Warner Cable and other cable TV providers have been pressuring channel owners to shun pacts with Intel and other Internet-based TV providers. Samsung, which ships millions of smart TVs, could distribute the service as a bundle, while Amazon could provide access to its growing library of movies and TV shows.

More OEM’s Seeking nVidia

As expected and announced, Zotac has now “joined the mobile gaming revolution” with the new Tegra Note 7 tablet and will be one of a handful of Nvidia partners that will sell it in both Europe and Asia-Pacific region for US $199.

In case you missed it yesterday when it was officially unveiled by Nvidia, the Nvidia Tegra Note 7 is based around a 7-inch 1280×800 IPS display and powered by Nvidia’s own Tegra 4 SoC with quad-core Cortex-A15 CPU and 72-core Geforce GPU paired up with 1GB of memory. It also packs some neat features exclusive to Nvidia, including a stylus with Nvidia DirectStylus technology as well as the 5-megapixel rear main camera backed by Chimera computational photography architecture revealed earlier by Nvidia. The camera will have support for both HDR as well as slow-motion video.

Unfortunately, Zotac did not announce the precise launch date so we are still stuck with Nvidia’s October time-frame and we are still to see the price of the new Tegra Note 7 in Europe.

Apple Hacked

A group of German hackers claimed to have successfully breached the iPhone fingerprint scanner on Sunday, just two days after Apple Inc debuted the technology that it promises will better protect devices from criminals and snoopers seeking access.

If the claim is verified, it will be embarrassing for Apple which is betting on the scanner to set its smartphone apart from new models of Samsung Electronics Co Ltd and others running the Android operating system of Google Inc.

Two prominent iPhone security experts told Reuters that they believed the German group, known as the Chaos Computing Club, or CCC, had succeeded in defeating Apple’s Touch ID, though they had not personally replicated the work.

One of them, Charlie Miller, co-author of the iOS Hacker’s Handbook, described the work as “a complete break” of Touch ID security. “It certainly opens up a new possibility for attackers.”

Apple representatives did not respond to requests for comment.

CCC, one the world’s largest and most respected hacking groups, posted a video on its website that appeared to show somebody accessing an iPhone 5S with a fabricated print. The site described how members of its biometrics team had cracked the new fingerprint reader, one of the few major high-tech features added to the latest version of the iPhone.

The group said they targeted Touch ID to knock down reports about its “marvels,” which suggested it would be difficult to crack.

“Fingerprints should not be used to secure anything. You leave them everywhere, and it is far too easy to make fake fingers out of lifted prints,” a hacker named Starbug was quoted as saying on the CCC’s site.

The group said it defeated Touch ID by photographing the fingerprint of an iPhone’s user, then printing it on to a transparent sheet, which it used to create a mold for a “fake finger.”

CCC said similar processes have been used to crack “the vast majority” of fingerprint sensors on the market.

“I think it’s legit,” said Dino Dai Zovi,” another co-author of the iOS Hacker’s Handbook. “The CCC doesn’t fool around or over-hype, especially when they are trying to make a political point.”

Touch ID, which was only introduced on the top-of-the-line iPhone 5S, lets users unlock their devices or make purchases on iTunes by simply pressing their finger on the home button. It uses a sapphire crystal sensor embedded in the button.

Data used for verification is encrypted and stored in a secure enclave of the phone’s A7 processor chip.

Two security experts who sponsored an impromptu competition offering cash and other prizes to the first hackers who cracked the iPhone said they had reviewed the information posted on the CCC website, but wanted more documentation.

“We are simply awaiting a full video documentation and walk through of the process that they have claimed,” said mobile security researcher Nick DePetrillo, who started the contest with another security expert, Robert Graham. “When they deliver that video we will review it.”

The two of them each put up $100 toward a prize for the contest winner, then set up a website inviting others to contribute. While the booty now includes more than $13,000 in cash, it was not clear that the CCC would receive the full payout, even if DePetrillo and Graham declared them winners.

Intel Goes AI

Intel has written a check for the Spanish artificial intelligence technology startup Indisys.

The outfit focuses on natural language recognition and the deal is worth $26 million. It follows Intel’s recent acquisition of Omek, an Israeli startup with specialties in gesture-based interfaces. Indisys employees have joined Intel already. Apparently the deal was signed on May 31 and the deal has been completed.

Intel would not confirm how they are using the tech: “Indisys has a deep background in computational linguistics, artificial intelligence, cognitive science, and machine learning. We are not disclosing any details about how Intel might use the Indisys technologies at this time.”

Are More Firms Moving To Tegra 4?

A curious rumor is coming out of Taiwan this morning. Nvidia is reportedly seeing more Tegra 4 orders, boosted by the Xiaomi Mi3 smartphone, Surface RT 2 and new tablets from Asus, Toshiba and HP. The source is Digitimes, or its moles in the “upstream supply chain” to be specific. Specific is not the word usually associated with such sources and we have no specific numbers to report.

However, while Nvidia is seeing a bit more interest for Tegra 4 it simply has no high-volume design wins and shipments will remain low until it is eventually phased out in favour of the Tegra 5. We wrote about Nvidia’s Tegra 4 volume woes last month, here.

The Tegra 4 still has just a handful of design wins and the fact that most of them are high-end tablets is not encouraging at all. Not much has changed since our previous report, although Nvidia did manage to land a single smartphone design win, albeit not a major one.

We still believe Tegra 4 shipments will be modest at best and new Android tablet design wins will not help much. Neither will the Shield and Tegra Note tablets.

FTC Warns Google And FB

The Federal Trade Commission (FTC) has promised that her organisation will come down hard on companies that do not meet requirements for handling personal data.

FTC Chairwoman Edith Ramirez gave a keynote speech at the Technology Policy Institute at the Aspen Forum. She said that the FTC has a responsibility to protect consumers and prevent them from falling victim to unfair commercial practices.

“In the FTC’s actions against Google, Facebook, Myspace and others, we alleged that each of these companies deceived consumers by breaching commitments to keep their data confidential. That isn’t okay, and it is the FTC’s responsibility to make sure that companies live up to their commitments,” she said.

“All told, the FTC has brought over 40 data security cases under our unfairness and deception authority, many against very large data companies, including Lexisnexis, Choicepoint and Twitter, for failing to provide reasonable security safeguards.”

Ramirez spoke about the importance of consumer privacy, saying that there is too much “shrouding” of what happens in that area. She said that under her leadership the FTC will not be afraid of suing companies when it sees fit.

“A recurring theme I have emphasized – and one that runs through the agency’s privacy work – is the need to move commercial data practices into the sunlight. For too long, the way personal information is collected and used has been at best an enigma enshrouded in considerable smog. We need to clear the air,” she said.

Ramirez compared the work of the FTC to the work carried out by lifeguards, saying that it too has to be vigilant.

“Lifeguards have to be mindful not just of the people swimming, surfing, and playing in the sand. They also have to be alert to approaching storms, tidal patterns, and shifts in the ocean’s current. With consumer privacy, the FTC is doing just that – we are alert to the risks but confident that those risks can be managed,” she added.

“The FTC recognizes that the effective use of big data has the potential to unleash a new wave of productivity and growth. Like the lifeguard at the beach, though, the FTC will remain vigilant to ensure that while innovation pushes forward, consumer privacy is not engulfed by that wave.”

It’s all just lip service, of course. Companies might be nominally bound by US privacy laws in online commerce, and that might be overseen by the FTC, but the US National Security Agency (NSA) collects all internet traffic anyway, and makes data available to other US government agencies and even some private companies.

Will The Tegra Processor Pay Off?

Last year Nvidia’s Tegra gamble seemed to be paying off nicely, but the insanely competitive SoC market moves fast and all it takes for things to go badly wrong is one botched generation. The Tegra 4 was late to the party and Nvidia eventually ended up with a big and relatively powerful chip that nobody wanted.

In its latest earnings call Nvidia made it clear that revenues from Tegra are expected to decline $200 to $300 million this year from about $750 million last year. Even this seems like a relatively optimistic forecast. Tegra 3 ended up in quite a few high-volume products, such as the Nexus 7, HTC One X, LG Optimus X4 and a bunch of other phones and tablets. On paper, Tegra 4 will end up with a similar number of design wins, maybe even more, but nearly all of them are low-volume products.

At the moment there are only a handful of Tegra 4 products out there. These include HP’s Slatebook 10, Toshiba eXcite Pro and eXcite Write tablets and Nvidia’s own Shield console. Nvidia’s 7-inch Tegra Tab is also on the way, along with the Surface RT 2. Some Chinese vendors like ZTE are also expected to roll out a Tegra 4 phone here and there, but the chip won’t end up in any big brand phones.

Nvidia does not release any Tegra unit shipment info, so we can only guess how many Tegra 3 and Tegra 4 chips are out there, but it doesn’t take much to realise Tegra 4 is a flop. Shipments of the original Nexus 7, powered by the Tegra 3, are estimated just north of six million units. Surface RT shipments were abysmal. Earlier this year analysts put the figure at just 900,000 units after a full quarter of sales. Microsoft eventually took a massive write-down on its Surface RT stock. LG and HTC didn’t reveal any shipment figures for the Optimus 4X and HTC One X, either. HTC shipped about 40 million phones last year, while LG managed about 27 million. We can’t even begin to estimate how many of them were flagship products powered by Tegra, but the number was clearly in the millions.

This time around Nvidia can’t count on strong smartphone sales, let alone the Nexus 7 and Surface RT. Even if it scores high-end tablet design wins, the truth is that high-end Android tablets just aren’t selling well. Nvidia needed high-volume design wins and Android tablets just won’t do the trick. Qualcomm is in the new Nexus 7 and the HTC One. Back in May analysts reported that HTC One sales hit the 5 million mark in the first two months of sales, although shipments have slowed down since then. Millions of Snapdragons found a home in the HTC One and millions more will end up in the new Nexus 7.

Nvidia’s talk of a $200 to $300 million hit this year doesn’t exactly paint the full picture. Tegra 3 shipments in the first two quarters of 2013 were modest, but relatively good. However, nothing took its place and the true extent of the Tegra 4 flop will only become visible in the first quarter of 2014 and beyond. The big hope is that the Tegra 4i and Tegra 5 will start to come online by then, so the numbers for the full year won’t be as terrible, but it is abundantly clear that Nvidia cannot afford another Tegra 4.

As for Nvidia’s Tegra Tab and Shield, they might do well. Nvidia knows a thing or two about hardware, but even if they prove successful, they just won’t be enough, at least not in this cycle.

Samsung’s Eight-core Chip Goes Hacking

A Samsung eight-core chip used in some Galaxy S4 mobile devices is now available for hackers to play with on a developer board from South Korea-based Hardkernel.

Hardkernel’s Odroid XU board has incorporated Samsung’s eight-core Exynos 5 Octa 5410 chip, which is based on ARM’s latest processor designs. Samsung recently announced a new eight-core chip, the Exynos 5 Octa 5420, which packs faster graphics and application processing than the 5410. The 5420 has not yet been shipped yet, however.

The Odroid board is priced at $149 through Aug. 31, after which it will be offered for $169. Samsung for many months has said that a board with an eight-core chip would be released, and has shown prototype developer boards at conferences.

Odroid-XU will provide developers an opportunity to write programs tuned for Samsung’s octa-core chip, which has been a source of controversy. Analysts have said the eight-core design is overkill for small devices like smartphones and tablets, which need long battery life.

The eight-core chip design also takes up a lot of space, which prevented Samsung from putting LTE radios inside some Galaxy S4 models. Qualcomm, which hesitantly moved from the dual core to the quad-core design on its Snapdragon chips, on Friday criticized eight-core chips, calling the idea “dumb.”

Despite the criticism, the board will give developers a first true glimpse of, and an opportunity to write and test applications for, ARM’s Big.Little design. The design combines high-power cores for demanding applications with low-power cores for mundane tasks like texting and calling.

Samsung’s iteration of Big.Little in the Exynos 5 Octa 5410 chip combines four processors based on ARM’s latest Cortex-A15 processor design, which incorporates four low-power Cortex-A7 CPUs. The Cortex-A15 is ARM’s latest processor design and succeeds the previous Cortex-A9 core, which was used in popular smartphones like Apple’s iPhone and the Galaxy S3. Samsung said the eight-core chip provides a balance of power and performance, with the high-power cores kicking in only when necessary.

The board has an Imagination Technologies PowerVR SGX544MP3 graphics processor, 2GB of low-power DDR3 DRAM, two USB 3.0 ports and four USB 2.0 ports. Other features include Wi-Fi, Ethernet and optional Bluetooth. Google’s Android 4.2 operating system is preloaded, and support for other Linux distributions like Ubuntu is expected soon. The board has already been benchmarked on Ubuntu 13.04.

Is nVidia Working On A Tablet?

According to a report over at Tabtech.de that managed to spot an unknown device in the result page of the GFXBench, Nvidia might be gearing up to release a phablet or tablet.

The device is listed as Nvidia Tegra Note Premium and scores just slightly lower than the Nvidia Shield in GFXBench. It feature Tegra 4 clocked at 1.8GHz and has a resolution of 1280×800 which probably points out to a tablet rather than phablet but everything is possible. It was running Android 4.2.2 Jelly Bean when it was tested.

At Computex 2013 back in June, Nvidia showcased a rather unique device that was used to demonstrate pressure-sensitive functions of a stylus and which might be the device that showed up in the GFXBench results. The 1280×800 resolution is not impressive and far off from what the competition currently has to offer, but then again Nvidia might want a cheaper tablet or phablet on the market.

In any case we will surely keep an eye out for Nvidia’s Tegra Note Premium, whatever it turns out to be.
