Apple patent filings outline input device gestures, solar iPods and iPhones
Apple's reputation as an innovator doesn't seem to be waning at all. Two recent patent applications published Thursday on the U.S. Patent and Trademark Office's Web site show that Apple is dreaming of new gestures using input devices and solar-powered iPods and iPhones. These applications are just a few of a recent parade of patents we've been following. While these are just filings for patent protection and not actual products, Thursday's "Methods and Apparatus for Processing Combinations of Kinematical Inputs" filing is very intriguing in light of the upcoming announcements. As described in the filing, "Some embodiments of the present invention therefore enable a user to provide a series of gestures as input to the receiving device. Such gestures may include, for example, brushing motions, scooping motions, nudges, tilt and slides, and tilt and taps. The application can then respond to each gesture (or gesture combination) in any number of ways." Hmmm... using a mouse on a "receiving device?" That could be an interesting way to perform tasks on a tablet device. We've heard some rumors about the tablet that describe new gestures that may take a bit of getting used to, and perhaps some of those are made to use a mouse in the manner described in the filing. It's also apparent that Apple is quite interested in making devices with virtually unlimited battery life. Another filing unveiled on Thursday, titled "Power Management Circuitry and Solar Cells," describes power management circuitry allowing portable devices like the iPod and iPhone to operate on solar power. The application details how both solar and battery power sources can be used to power the devices, using switches to reconfigure solar cells on the fly so that the device receives a constant voltage even when some cells are "shadowed" by a hand. How about it, TUAW readers? Are you ready for a solar-powered tablet you can tap, brush, and nudge with a solar mouse? It could happen some day, although these are patentable ideas and not actual products. [via MacRumors]
Apple patent application two-fer: new gesture inputs, solar-powered iPods?
We know it's been tough with the dearth of Apple-related speculation as of late, but it looks like we now finally have a few more clues about what the company might be up to courtesy of a pair of recently published patent applications. The first of those is a new type of gesture-based input device, which would not only be able to detect swipes and other simple gestures, but things like brushing or scooping motions that take into account force and velocity (check out an example after the break). The other patent treads a bit of familiar territory for Apple, and describes a built-in solar power system for electronic devices -- such as an iPod, as illustrated above. That could apparently include solar cells covering the entire device, which could be configured to function even if they're partly obstructed by your hand. The system would also supposedly be able to detect if the battery is completely drained and rely solely on the solar cells to power up the device or, alternatively, switch the solar cells to a "second operational state" if it detects that the battery is charged -- if it ever actually exists, that is.
Self-assembling solar cells built using ancient wisdom, modern technology
Alright, so self-assembling electronics are hardly new in and of themselves, and nanoscale tech tends to always come with bombastic promises, but you don't wanna miss how this latest innovation is built. Two professors from the University of Minnesota have successfully demonstrated a self-assembly technique that arranges microscopic electronic elements in their proper order thanks to the absolute enmity that exists between water and oil. By coating elements with a hydrophilic layer on one side and some hypdrophobic goo on the other, they've achieved the proper element orientation, and the final step in their work was the insertion of a pre-drilled, pre-soldered sheet, which picks up each element while being slowly drawn out of the liquid non-mixture. The achievement here is in finding the perfect densities of water and oil to make the magic happen, and a working device of 64,000 elements has been shown off -- taking only three minutes to put together. If the method's future proves successful, we'll all be using electronics built on flexible, plastic, metal, or otherwise unconventional substrates sometime soon.
JA Solar and Innovalight team up to commercialize 'silicon ink' solar cells
We've seen a few different approaches to printable, and occasionally paintable solar cells over the years, but it looks like JA Solar was particularly taken with Innovalight's so-called silicon ink-based solar cells, and it's now announced that its teaming up with the company to commercialize the technology. In addition to being "printable" and cheaper to manufacture than traditional solar cells, the company also claims that the silicon ink solar cells also boast an impressive 18 percent conversion efficiency, which has apparently just been backed up by both the U.S. Department of Energy's National Renewable Energy Laboratory and The Fraunhofer Institute for Solar Energy Systems. Details on the deal are otherwise a bit light, but JA Solar says that it'll manufacture the new cells using its existing solar cell manufacturing lines, which should lower the cost even further and, if all goes as planned, allow for "initial commercialization" sometime in 2010.[Via CNET News Green Tech]
Baby steps: new solar cell efficiency record isn't awe-inspiring
Granted, we've no idea what it takes to really push the efficiency level of a solar cell, but we're getting pretty bored with these incremental improvements year after year. If you'll recall, the record for solar cell efficiency sat at 40.7 percent in 2006, and that was raised to an amazing 40.8 percent last August. Today, researchers at the Fraunhofer Institute for Solar Energy Systems have announced an all new milestone: 41.1 percent efficiency. According to team head Frank Dimroth, the crew is simply "elated by this breakthrough." Meanwhile, the rest of planet Earth is suddenly depressed by the thought of perishing from old age before this data point ever breaks the big five-oh.[Via Gizmag]
MIT spin-off 1366 Technologies touts better, cheaper solar cells
In what's become an increasingly familiar tune, a startup company has announced that it's just pulled in a significant haul of funding based on its promises of better, cheaper solar power. In this case, the company in question is 1366 Technologies, which was spun out of research from MIT and is headed by MIT professor Ely Sachs (who is taking a leave of absence to focus on the company). According to the company, it's found a way to make solar cells from multicrystalline silicon that are just as efficient as ones from single-crystal silicon, which is normally much more expensive to produce. In terms of hard numbers, that translates to solar cells that are 27 percent more efficient than your average solar cell, and (in its current state) a cost a $2.10 per watt. Sachs says that cost will come down to $1.65 per watt when manufacturered on a commercial scale, however, and will eventually drop to $1.30 a watt with some "planned improvements." That's still short of the $1 a watt goal they're aiming for (which is roughly the cost of coal), but the company seems confident they can hit that mark by 2012 with some "anticipated advances."[Via Physorg]
Graphene could be used in creating solar cells, LCDs
Not to sound alarming or anything, but apparently, we've only got a decade or so before our planet runs clean out of indium. Thankfully for us, a team of researchers at the Max Planck Institute for Polymer Research in Germany are purportedly onto a replacement. For those in the dark, indium is a critical resource in "creating solar cells, LCD and other devices which must have transparent electrodes to carry out their function," but the aforementioned crew has seemingly been able to take graphene ("single layer 2D sheets extracted from the common material graphite") and build an acceptable alternative. The creation is 80-percent transparent to visible light and 100-percent transparent to infrared light, which could actually lead to solar cells capable of soaking up even more energy from more of the EM spectrum. 'Course, there's no telling how close this discovery is to being commercially viable, but we suppose we could always resurrect RPTVs and rely solely on wind farms for renewable energy if necessary, right?

Silicon nanowire could convert light into electrical energy
Nanoelectonic devices have to have juice too, and thanks to a team at Harvard University, extraordinarily minuscule gizmos of the future could be powered via a "silicon nanowire that can convert light into electrical energy." The device itself is said to look much like a typical coaxial cable, but it's around 100,000 times smaller and shuns metal in favor of "silicon with three different types of conductivity arranged as layered shells." Reportedly, a single strand can output "up to 200-picowatts," which won't move much, but it could be just enough to run ultralow power electronics that could be worn on, or even inside, the body. Hopefully they'll have this all ironed out by the time we need a pacemaker.[Image courtesy of Harvard]
Solar cell breakthrough: 40% efficiency achieved
If that silly Hummer O2 concept vehicle we just saw didn't sate your appetite for environmental friendliness, try this on for size: researchers at Boeing-Spectrolab have just succeeded in building a multi-junction solar cell that achieves an incredible 40.7% efficiency, or -- to the best of our knowledge -- about twice that of the reigning champ in this space. To put this Department of Energy-backed breakthrough in perspective, it was less than two months ago that Silicon Valley-based SunPower announced a 22% efficient cell, and even that model was claimed to produce 50% more power over a given space than previous iterations. In case you're unfamiliar with multi-junction cells -- no shame in that game -- they can best be described as being composed of several layers, with each slice capturing only a portion of the solar spectrum; this method of optical concentration is what has allowed cells to surpass the 12% to 18% efficiency barrier faced by most traditional modules. In conclusion, while this is certainly an encouraging development, we remain somewhat skeptical about its potential for real-world implementation: once Big Oil gets wind of this new tech, it will likely "disappear" just as quickly as that guy who invented a car that runs on water, man.[Via Slashdot]
