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.

Is Windows ‘Threshold’ Enroute?

Microsoft will unveil a preview of “Threshold,” the current code name for Windows 8′s successor, as soon as next month, according to an online report on Monday.

ZDNet’s Mary Jo Foley, citing unnamed sources, said that Microsoft will deliver a “technical preview” of Threshold late in September or early in October. Previously, Foley had reported that Microsoft would offer a preview of some kind this fall.

Threshold may be officially named “Windows 9″ by Microsoft — the company has said nothing about either the code name or labeled the next iteration of its desktop and tablet OS — although there are arguments for dumping a numerical title because of the possible association with Windows 8, which has widely been pegged as a failure.

“Technical Preview” is a moniker that Microsoft has used in the past for its Office suite. For both Office 2013 and Office 2010, Microsoft used the term to describe an invitation-only sneak peek. Both application suites were later released as public betas prior to their official launch.

Windows, however, has used a different nomenclature. For 2012′s Windows 8, Microsoft called the early looks ”Developer Preview,””Consumer Preview” and “Release Preview,” all open to everyone. The first was analogous to an alpha, the second to a beta, and the third to a done-but-not-approved release candidate.

Windows 7, however, had used the more traditional “Beta” to describe the first public preview in early 2009. The previous fall, when Microsoft unveiled Windows 7, the firm had seeded an invite-only “pre-alpha” version, also dubbed a Developer Preview, of the OS to programmers and some influential bloggers.

Within hours, the Windows 7 Developer Preview leaked to file-sharing websites. Microsoft may have changed its practices for Windows 8, letting anyone download the first preview, because of the inevitably of leaks.

In an update to her blog of earlier today, Foley added that the “Technical Preview” nameplate notwithstanding, Microsoft would allow anyone to download Threshold/Windows 9 when it becomes available in the next few weeks.

If Microsoft does ship a preview soon and sets its sights on a second-quarter 2015 final release, it will have significantly accelerated the tempo from past practice. With Windows 7 and Windows 8, Microsoft offered its first previews 12 and 13 months, respectively, and the public beta 8 or 9 months, before launching the operating system.

Eight or nine months from September would be May or June 2015; that, however, assumes that the Technical Preview is of beta quality. The name itself hints at something less.

Microsoft appears eager to put Windows 8 behind it. It has stopped beating the drum about the OS and recently announced that it would not issue any additional major updates. Instead, the firm said last week, it will include improvements or new features in small packets using the same Windows Update mechanism that regularly serves security patches.

Apple Changes Policy In China

Apple Inc has started the processing of keeping the personal data of some Chinese users on servers in mainland China, marking the first time the tech giant is storing user data on Chinese soil.

The storage of user data in China represents a departure from the policies of some technology companies, notably Google Inc, which has long refused to build data centers in China due to censorship and privacy concerns.

Apple said the move was part of an effort to improve the speed and reliability of its iCloud service, which lets users store pictures, e-mail and other data. Positioning data centers as close to customers as possible means faster service.

The data will be kept on servers provided by China Telecom Corp Ltd, the country’s third-largest wireless carrier, Apple said in a statement.

“Apple takes user security and privacy very seriously,” it said. “We have added China Telecom to our list of data center providers to increase bandwidth and improve performance for our customers in mainland china. All data stored with our providers is encrypted. China Telecom does not have access to the content.”

A source with knowledge of the situation said the encryption keys for Apple’s data on China Telecom servers would be stored offshore and not made available to China Telecom.

Apple has said it has devised encryption systems for services such as iMessage that even Apple itself cannot unlock. But some experts expressed scepticism that Apple would be able to withhold user data in the event of a government request.

“If they’re making out that the data is protected and secure that’s a little disingenuous because if they want to operate a business here, that’d have to comply with demands from the authorities,” said Jeremy Goldkorn, director of Danwei.com, a research firm focused on Chinese media, internet and consumers.

“On the other hand if they don’t store Chinese user data on a Chinese server they’re basically risking a crackdown from the authorities.”

Goldkorn added that data stored in the United States is subject to similar U.S. regulations where the government can use court orders to demand private data.

A spokesman for China Telecom declined to comment.

Will Sprint Cut It’s Staff?

Sprint’s new CEO Marcelo Claure addressed employees for the first time and promised price reductions are coming very soon, according to a report.

Sprint didn’t deny the report of Marcelo’s comments. A spokesman also confirmed Friday that Sprint is “focusing on providing the best value in the market.”

According to the account of Claure’s comments, he told workers, “We’re going to change our plans to make sure every customer in America thinks twice about signing up to a competitor.” The report, which first appeared in LightReading.com, also said that “very disruptive” rate plans are coming this week.

Sprint didn’t dispute Light Reading’s report, but a spokesman said Sprint is not commenting on “any potential pricing plans before they are announced.”

The spokesman, Doug Duvall, said Marcelo held his first all-employee town hall meeting before a standing-room-only crowd. He added: “He shared his passion for his family, work and soccer team and his commitment to leading Sprint. He discussed Sprint’s challenges and pledged to get Sprint ‘back in the game’ by focusing on providing the best value in the market, completing our network build and optimizing Sprint’s cost structure.”

By confirming Sprint wants to offer the “best value in the market,” it’s pretty clear that Sprint, the third-largest U.S. carrier, will soon wage a price war with the T-Mobile, the fourth-largest U.S. carrier that has quickly been gaining on Sprint.

Analysts recently said Sprint’s recent “Framily plan” isn’t competitive in the market, which former CEO Dan Hesse acknowledged in late July before his departure on Monday.

The Sprint Framily plans costs $160 a month for 4GB of data, but comes with overage charges and won’t allow tethering. Meanwhile, T-Mobile has a family plan offered through September that costs $100 a month for four lines and 10GB of data, although each line is limited to 2.5GB.

Hesse had earlier described subscriber plans Sprint was testing that have tiers of data and unlimited data.

According to Light Reading, Claure also told employees that price cuts are needed because Sprint’s network isn’t at the level of performance and reach that it should be. “When you have a great network, you don’t have to compete on price,” he reportedly said. “When your network is behind, unfortunately you have to compete on value and price.”

HTTP2 Procotol Nears Completion

When it comes to amping up traffic over the Internet, sometimes too much of a good thing may not be such a good thing at all.

The Internet Engineering Task Force is putting the final touches on HTTP/2, the second version of the Hypertext Transport Protocol (HTTP). The working group has issued a last call draft, urging interested parties to voice concerns before it becomes a full Internet specification.

Not everyone is completely satisfied with the protocol however.

“There is a lot of good in this proposed standard, but I have some deep reservations about some bad and ugly aspects of the protocol,” wrote Greg Wilkins, lead developer of the open source Jetty server software, noting his concerns in a blog item posted Monday.

Others, however, praise HTTP/2 and say it is long overdue.

“A lot of our users are experimenting with the protocol,” said Owen Garrett, head of products for server software provider NGINX. “The feedback is that generally, they have seen big performance benefits.”

First created by Web originator Tim Berners-Lee and associates, HTTP quite literally powers today’s Web, providing the language for a browser to request a Web page from a server.

Version 2.0 of HTTP, based largely on the SPDY protocol developed by Google, promises to be a better fit for how people use the Web.

“The challenge with HTTP is that it is a fairly simple protocol, and it can be quite laborious to download all the resources required to render a Web page. SPDY addresses this issue,” Garrett said.

While the first generation of Web sites were largely simple and relatively small, static documents, the Web today is used as a platform for delivering applications and bandwidth intensive real-time multimedia content.

HTTP/2 speeds basic HTTP in a number of ways. HTTP/2 allows servers to send all the different elements of a requested Web page at once, eliminating the serial sets of messages that have to be sent back and forth under plain HTTP.

HTTP/2 also allows the server and the browser to compress HTTP, which cuts the amount of data that needs to be communicated between the two.

As a result, HTTP/2 “is really useful for organization with sophisticated Web sites, particularly when its users are distributed globally or using slower networks — mobile users for instance,” Garrett said.

Verizon Wins Top Honors

RootMetrics awarded Verizon Wireless its seal of approval in its latest biannual ranking of wireless network performance in cities across the U.S.

Verizon ranked first or was tied for first in 115 of 125 cities for overall network performance during the first half of 2014, leading all three other national carriers — AT&T, Sprint and T-Mobile.

Sprint didn’t finish first in any of the cities, while Verizon tied with either AT&T or T-Mobile, or both, in 56. That meant that AT&T was the only first place finisher in 59 cities, including major cities such as Cincinnati, Colorado Springs, Colo., Daytona Beach, Fla., Detroit, Los Angeles, Miami, Minneapolis, Nashville, Salt Lake City, San Antonio and Seattle.

RootMetrics found that Verizon finished first in 23 of 50 airport network evaluations for the first half of the year and tied for first in seven out of 50 airports. Verizon won or tied at four major airports: Atlanta, Chicago, Los Angeles and Denver.

Verizon has its 4G LTE network in 500 U.S. cities, providing access to 97% of the U.S. population. RootMetrics used devices capable of connecting to Verizon’s XLTE network, now operating in 300 cities.

XLTE uses AWS spectrum.

RootMetrics is an independent research company that uses testers driving in cars and in stationary locations, both indoors and outdoors, to conduct thousands of tests in each city to evaluate reliability and speed of connections and call, data and text performance. The company uses unmodified smartphones purchased off-the-shelf from operator stores.

Microsoft Updates Office Online

Microsoft is updating its Web-based Office Online suite, closing the features gap with the main Office 365 and Office 2013 suites installed on users’ devices.

“We know you want features that allow you to move as seamlessly as possible between Office Online and the desktop,” wrote Kaberi Chowdhury, an Office Online technical product manager, in a blog post Monday.

Improvements to Excel Online include the ability to insert new comments, edit and delete existing comments, and properly open and edit spreadsheets that contain Visual Basic for Applications (VBA) code.

Meanwhile, Word Online has a new “pane” where users can see all comments in a document, and reply to them or mark them as completed. It also has a refined lists feature that is better able to recognize whether users are continuing a list or starting one. In addition, footnotes and end notes can now be added more conveniently inline.

PowerPoint Online has a revamped text editor that offers a layout view that more closely resembles the look of finished slides, according to Microsoft. It also has improved performance and video functionality, including the ability to play back embedded YouTube videos.

For users of OneNote Online, Microsoft is now adding the ability to print out the notes they’ve created with the application.

Microsoft is also making Word Online, PowerPoint Online and OneNote Online available via Google’s Chrome Web Store so that Chrome browser users can add them to their Chrome App launcher. Excel Online will be added later.

The improvements in Office Online will be rolled out to users this week, starting Monday.

Office Online, which used to be called Office Web Apps, competes directly against Google Docs and other browser-based office productivity suites. It’s meant to offer users a free, lightweight, Web-based version of these four applications if they don’t have the desktop editions on the device they’re using at that moment.

What Do Smaller Controllers Mean?

If you want a wearable Internet of Things, the electronics have to be as tiny and as energy efficient as possible. That’s why a new microcontroller by Freescale Semiconductor is noteworthy.

The company has produced the Kinetis KLO3 MCU, a 32-bit ARM system that is 15% smaller than its previous iteration but with a 10% power improvement.

Internet of Things is a buzzword for the trend toward network-connected sensors incorporated into devices that in the past were standalone appliances. These devices use sensors to capture things like temperatures in thermostats, pressure, accelerometers, gyroscopes and other types of MEMS sensors. A microcontroller unit gives intelligence and limited computational capability to these devices, but is not a general purpose processor. One of the roles of the microcontroller is to connect the data with more sophisticated computational power.

The Kinetis KLO3 runs a lightweight embedded operating system to connect the data to other devices, such as an app that uses a more general purpose processor.

Kathleen Jachimiak, product launch manager at Freescale, said the new microcontroller will “enable further miniaturization” in connected devices. This MCU is capable of having up to 32 KB of flash memory and 2 KB of RAM.

Consumers want devices that are light, small and smart. They also want to be able to store their information and send it to an application that’s either on a phone or a PC, Jachimiak said.

This microcontroller, at 1.6 x 2.0 mm, is smaller than the dimple on a golf ball, and uses a relatively new process in its manufacturing, called wafer level chip scale packaging. The process involves building the integrated package while the die is still part of a wafer. It’s a more efficient process and produces the smallest possible package, for a given die size.

New USB Chip Developed

Silicon Motion says it has begun shipping samples of a new USB 3.0 controller chip for flash drives that could boost performance by up to 50%.

The company said the new SM3267 integrated controller is expected to deliver up to 160MB/s read, and 60MB/s write speeds through a single channel; that would be a 30% to 50% performance improvement over today’s USB 3.0 flash drive technology.

Even though the USB 3.0 specification has the capability to support 4.8Gbps throughput speeds, the speed of a USB 3.0-enabled flash drive is dictated by the speed of the accessing flash devices in the drive. Today, most consumer-USB 3.0 flash drives support about 100MB/s read speeds.

We are pleased to announce that SM3267 has received design-ins from most of our current USB controller customers, including many top-tier OEMs, and we expect SM3267-based USB 3.0 flash drives will be commercially available starting in the fourth quarter of 2013,” Wallace Kou, CEO of Silicon Motion, said in a statement.

The new integrated chip will also be able to run at lower voltages, from 5 volts to 1.2 volts, enabling a 25% to 30% lower USB flash drive device temperature compared with other USB 3.0 flash controller products in the market, Silicon Motion said.

The new IC will support the vast majority of NAND flash technology, including new triple-level cell (TLC), multi-level cell (MLC), high speed Toggle, and ONFI DDR NAND manufactured by Samsung, Toshiba, SanDisk, SK Hynix, Micron and Intel.

The new chip has already passed both USB-IF compliance testing and WHCK (Windows Hardware Certification Kit) tests for Windows 7 and Windows 8.

The new IC is available in a Chip-on-Board (COB) and in a 48-pin QFN green package.

King.com Has IPO In The Works

King.com Ltd, the British mobile gaming firm best known for its popular puzzle game ‘Candy Crush Saga’, has filed confidentially for an initial public offering (IPO) in the United States, a person familiar with the matter said on Sunday.

Online technology companies are rushing to the stock market on the backs of Twitter Inc’s announcement earlier this month that it plans to go public in the most eagerly anticipated IPO since last year’s flotation ofFacebook Inc.

Emerging growth companies such as King can use a secretive IPO registration process in the U.S. thanks to the Jumpstart Our BusinessStartups (JOBS) Act, which loosened a number of federal securities regulations in hopes of boosting capital raising and thereby increasing job growth.

King has hired Bank of America Merrill Lynch Corp, Credit Suisse Group AG and JPMorgan Chase & Co to lead the offering, said the person, confirming an earlier report by the Daily Telegraph and asking not to be identified because the information is confidential.

Representatives for King and the banks either declined to comment or did not respond to requests for comment.

King offers 150 games in 14 languages through mobile phones, Facebook and its website. It boasts more than 1 billion gameplays per day from its users.

The company’s games appeal to a growing trend for players to play puzzles with their friends in short bursts, especially as games are increasingly played on the move on phones or tablets to kill spare minutes.

Rival Zynga Inc went public two years ago in a high-profile IPO that raised $1 billion. Since then, Zynga has suffered from sagging morale during several quarters of worsening performance and repeated waves of layoffs.

Founded in 2003, King has been profitable since 2005 and has not had a funding round since September of that year, when it raised 34 million euros ($46.04 million) from investment firms Apax Partners and Index Ventures.
