Apple has applied for a patent for an interesting take on wireless charging, allowing a Smart Cover with embedded battery to recharge the iPad (discovered by AppleInsider).

At first blush, Apple's invention, aptly titled "Integrated inductive charging in protective cover," appears to simply be a first-party incarnation of upcoming products that use inductive charging to transfer power to an iOS device. These components usually incorporate an induction coil and transformer that outputs power via a cord plugged into the device's dock connector. Apple's patent filing describes something different.

Instead of sourcing power from a stationary dock, Apple's invention calls for a tablet case, or more specifically an iPad Smart Cover, to hold the inductive power transmitter. In some embodiments, an internal battery is disposed within the case, basically creating an "on-the-go" wireless charger.

Wireless charging efficiency relies on close proximity between the transmitting and receiving induction coils. Apple's existing Smart Cover magnet system uses magnets with alternating polarities to ensure a precise alignment of cover to iPad, a pairing that would help optimize the charging system.

The system would automatically charge the iPad when the cover is closed, with the cover itself being charged conventionally by plugging it into a power source via USB, although Apple notes that solar cells could also be incorporated into the cover.

Apple has had a long-standing interest in various forms of wireless charging, but the technology has yet to make its way into the company's mobile devices. Just last week, a report suggested that Apple may be introducing wireless charging the iPhone as soon as this year, although it seems like a relatively unlikely addition for the iPhone 5S.

Alongside last year's introduction of the new Lightning connector, Apple marketing chief Phil Schiller downplayed the importance of wireless charging, although Apple executives have been known to dismiss certain features only to introduce them in future products.

As ever, we note that Apple applies for patents on a significant number of ideas that never make it into production, but wireless charging is growing in popularity and it seems likely that Apple will introduce it at some point in the future.

Digitimes reports that Taiwan Semiconductor Manufacturing Company (TSMC) will "tape out" the design for an A7 system-on-a-chip built on a 20-nanometer process this month. Taping out refers to the initial design of the chip having been completed for creation of the masks that will be used to print the actual chips, although further tweaks are likely as test production is carried out.

Taiwan Semiconductor Manufacturing Company (TSMC) is expected to tape out Apple's A7 processor on a 20nm process in March and then move the chip into risk production in May-June, which will pave the way for commercial shipments in the first quarter of 2014, according to industry sources.

The report claims that TSMC will be using its "14-fab" facility at the Tainan Science Park in Taiwan to build the chips.

We talked with Silicon-IP founder and former TSMC director Kurt Wolf about the report, and he notes that TSMC did achieve certification on its 20-nm process in December, although a significant amount of work remains before production-worthy chips will be ready.

With Apple undoubtedly preparing to launch new iPhone and iPad models this year before the rumored 20-nm A7 is ready in early 2014, Wolf points out that Apple has a number of options for this year's lineup. Those options include smaller and more efficient versions of the existing A6 family based on a 28-nm process rather than the current 32-nm process, a more substantially modified A6 to boost power, or a new A7 chip built on the 28-nm process before being moved to 20-nm next year. Wolf believes that Apple will be using both Samsung and TSMC to build its 2013 chips.

A report from last October had claimed that Apple and TSMC would be working together on 20-nm chips for 2014, and today's report seems to be in line with those claims. Earlier this week, we discovered a smaller version of the A5 chip inside the tweaked Apple TV and initially thought that it might be built on a smaller process node or come from TSMC, but further examination revealed that it is still a 32-nm chip from Samsung. It has, however, undergone a substantial redesign in order to achieve a nearly 50% reduction in size.

As noticed by Macworld UK, Apple today introduced a new configuration option for its 21.5-inch and 27-inch iMacs, allowing customers to choose a VESA mount adapter instead of the standard foot. The $40 option allows users to mount their iMacs to walls or other vertical surfaces, but must be configured at the time of purchase.

The iMac with Built-in VESA Mount Adapter is ready to pair with your favorite VESA-compatible wall mount, desk mount, or articulating arm (sold separately). This iMac doesn't include a stand, so a mount is required. If you don't already have a mount, you can purchase one when you configure your iMac.

Apple is currently quoting shipping estimates of 7-10 business days for VESA-equipped iMacs, compared to immediate availability for standard models.

Apple marketing chief Phil Schiller went on the offensive against Android in a unusually forthright interview with The Wall Street Journal.

Mr. Schiller, Apple's senior vice president of world-wide marketing, also said that Android users are often running old operating systems and that the fragmentation in the Android world was "plain and simple."

He added that "Android is often given a free replacement for a feature phone and the experience isn't as good as an iPhone."

In addition to the above comments, Schiller said that Android devices and the operating system "don't work seamlessly together" because they come from different vendors, unlike Apple which makes both the software and hardware in its devices.

Samsung is expected to announce an update to its flagship Galaxy S smartphone line tomorrow.

For the past few days, we've been following the story of the smaller A5 chip found inside of the recently tweaked Apple TV, seeking to understand what changes Apple has made in order to shrink the chip to roughly half the size of the previous A5 chip.

Yesterday, experts at Chipworks determined that the new A5 was still being manufactured by Samsung using the same 32-nanometer process used for the previous version, indicating that Apple had undertaken significant design changes for the chip.

Chipworks now has a full image of the A5 die, revealing that this smaller A5 chip contains only a single-core ARM CPU. Apple has listed the Apple TV as having a single-core A5 since the third-generation model launched last year, but the previous design involved a dual-core chip with one core disabled, while the new design contains just the one active core. The new A5 does still contain the same dual-core GPU found in the previous version of the chip.

Chipworks' Dick James tells us, however, that there must be more to the story in order to achieve a nearly 50% size reduction, but the firm has yet to determine exactly what other changes are contributing to the smaller die size.

A separate observation of interest involves the analog circuitry included on the chip. This new A5 chip appears to take advantage of optimized analog components such as resistors, capacitors, and inductors, yielding a mixed signal chip that seems to be a rather significant technical achievement at the 32-nanometer process node.

My guess is that the analog sections have been re-designed, always a work in progress when we get this small, since analog circuitry does not shrink anywhere near as predictably as digital. And as Jim said earlier, we think this is now in a mixed-signal version of the 32-nm process that allows extra passive components such as resistors, capacitors, and inductors, that is much more suited to analog stuff.

It is still unclear exactly why Apple has elected to redesign the A5 for the Apple TV, as it has been assumed that the company's "hobby" does not generate enough shipment volume to warrant such an investment in and of itself. As a result, it is possible that Apple has plans to use this chip in other products, although the single-core nature of the CPU design will likely limit the range of devices for which it would be suitable.

A U.S. District Judge has ordered Apple CEO Tim Cook to sit for a deposition in the antitrust lawsuit filed by the Justice Department against the company over alleged e-book price-fixing, reports Reuters.

U.S. District Judge Denise Cote in Manhattan granted the Justice Department's request to compel Cook to testify for four hours in the lawsuit, which accuses Apple of conspiring with five publishers to raise e-book prices.

The government had argued Cook likely had relevant information about Apple's entry into the e-books market. It also said Cook likely had conversations related to e-books with former Apple CEO Steve Jobs, who died in 2011.

The lawsuit was originally filed in April of 2012, and has focused on the so-called 'agency model' for pricing ebooks that Apple attempted to negotiate with a number of publishers.

The Department of Justice has settled with all of the book publishers initially accused, while Apple remains the main target of the suit.

Back in January, we noted that office supply chain Staples appeared to gearing up to begin selling Apple products in its U.S. stores for the first time. Staples employees confirmed the announcement several weeks later and late last month the company began selling Apple accessories in its U.S. online store.

Apple accessories have already been making their way to some brick-and-mortar Staples stores, with our sources indicating that at least some locations will also be selling a broader range of products, including Macs, iPads, and iPhones.

One source has now shared screenshots of training materials for Staples sales associates, revealing training modules addressing not only the Apple TV currently being offered Staples but also Mac notebooks, iPhones, and iPads. It is unclear if Mac desktops are not going to be carried by Staples or if perhaps those offerings will be limited to certain locations.

Staples' curriculum description for iPhone 5 training reads:

At the end of this curriculum, associates will be able to describe key features of the Apple iPhone 5, and suggest attachments that compliment the iPhone 5.

Notably, all of the training modules addressing Apple products carry completion due dates of March 26 or 27, suggesting that the rollout of those products to Staples stores is likely to occur very soon after.

Staples operates over 1,500 retail stores in the United States, marking a significant expansion of Apple's distribution chain. The new outlet also offers an appealing channel for businesses that may already have billing accounts and other existing relationships with Staples for their office supply needs.

Bloomberg reports that regional and rural carriers in the United States are banding together to back legislative efforts to ease the unlocking of mobile phones. Unsurprisingly, the smaller carriers see unlocking as a key way to attract new customers and gain access to the most popular handsets such as the iPhone.

“Smaller carriers have a very difficult time getting access to smartphones and handsets,” said Steven Berry, president of the Competitive Carriers Association, which represents such companies as U.S. Cellular Corp. (USM) and Bluegrass Cellular. “The unlocking is one way the consumer can make the decision that I can try someone else who has better coverage in the area where I live or play.”

Unauthorized unlocking of newly purchased mobile phones became illegal in the U.S. as of late January, but the White House has backed an effort to address the issue and Congress has begun putting forward bills that would clear the way for broader unlocking abilities.

AT&T has made clear that the ruling against unauthorized unlocking has very little impact on its customers, as the carrier's current policy is to unlock any device that is no longer under contract and for which the customer's account has been active for at least 60 days and carries no balance due. Current efforts, however, seek to loosen unlocking restrictions more uniformly across carriers.

Apple has made significant strides in extending iPhone availability to smaller U.S. carriers over the past several years, with 18 carriers now offering the device. Many more are undoubtedly interested in joining that group, and making it easier for customers to bring their out-of-contract iPhones to new carriers would likely help these carriers bring more of these customers onboard.

Samsung's lead over Apple last year in the smartphone race was helped by a massive marketing blitz, reports The Wall Street Journal.

Figures published by Kantar Media showed that in 2011, Apple was outspending Samsung three-to-one in mobile phone advertising (red graphics). Samsung massively increased its phone advertising spending from $78 million in 2011 to $401 million in 2012, 20% higher than Apple's $333 million.

The willingness to spend heavily could prove even more important as the technology gap between rivals narrows.

"They understand how to build a strong product...and have been willing to invest to drive their success," said Michael Sievert, chief marketing officer of T-Mobile USA Inc., a unit of Deutsche Telekom DTE.

To be sure, Apple remains a powerful brand that benefits from its own advertising and ubiquitous references in popular culture. Apple's iPhone is America's most effective mobile phone brand, advertising analytics firm Ace Metrix said in January. But Samsung finished second in phones and was the top technology brand of 2012, said Ace.

Samsung has been running a high-profile teaser campaign for its Galaxy S IV phone due to be launched tomorrow at Radio City Music Hall, and will undoubtedly continue that push with even more advertising to drive sales of the new flagship device.

Just weeks ago, Ken Segall, the creative director behind several of Apple's ad campaigns including the iconic "Think Different" effort, highlighted the effectiveness of Samsung's people-based ads, arguing that Apple needs to step up its game in order to counter Samsung's marketing successes.
