Watch out, battery-powered MAVs -- your viability could be seriously in danger. Based on a patent application from University of Florida aerospace engineer Subrata Roy, he's reckoning that a micro air vehicle could be propelled by plasma. Scientists have known that passing a current or magnetic field through a conducting fluid generates a force, but exploiting it for use in moving an aircraft has proven futile thus far. The phenomenon, simply known as magnetohydrodynamics, has typically been tested on larger crafts, but Mr. Roy's invention would boast a wingspan of less than 15-centimeters and resemble a flying saucer more so than a 747. Of course, this fantastic idea has yet to become much more than just that, but for armed forces and entities obsessed with surveillance, this could undoubtedly be big.

We'll be straight with you -- we've never actually waltzed through the rooms at Engadget HQ and had the urge to reproduce the exact output from light A with light B. Evidently, we're the exception and not the rule. According to a lingering patent application from Philips, it's seeking to create a system in which sensors could be used to detect "light attributes" from one location and paste them over to another location in order to produce perfectly uniform scenarios throughout the home / office / etc. Heck, it even details a memory bank in order to easily set the mood of the entire building when necessary. Can't say this is where we envisioned the future of copy-and-paste going, but we suppose it'll do.

It's no secret that Apple loves its touchscreens, and a freshly published patent application provides a little reinforcement to that belief. The documentation explores a method for tossing in pressure-sensitivity to touchpads in order to add functionality, or as Cupertino puts it, "a new element of control." Furthermore, it's noted that "force information may be used as another input dimension for purposes of providing command and control signals to an associated electronic device," and it goes on to explain how spring membranes could be placed under the surface to detect force. Notably, the verbiage tends to "describe a touchpad like those used for the company's MacBook lines," but it does leave open the possibility for the newfangled pads to be used in mobile / portable devices such as the outfit's own iPhone.

We've seen a wide array of devices that tip off the good guys to approaching enemies, hunt down IEDs, and send back live video of opposing camps, but a new patent application lays out plans to construct a specialized net that could actually detonate incoming grenades or rockets before they strike their intended target(s). More specifically, the app calls for a "protection system featuring a flexible packaged net" that could be attached to a military vehicle, which could then be deployed if onboard sensors pick up "incoming threats" such as an RPG. Another perk would be the relatively low cost of manufacturing and the ease of moving from one tank to another, but as these things always go, there's no telling when (or if) we'll see this technology in action.

Hey, it's no shocker that Apple's iPod is a coveted item even for those who acquire their wares in less than legal manners, but a recent patent application from Apple shows that someone at Cupertino cares about you rightful owners out there. Essentially, the technology would invoke a "guardian" recharge circuit, which would disable any further charging if the computer (or "other recharger") it was paired with was of the unauthorized variety. According to Apple, this type of limitation would "serve as a deterrent to theft," and while we can only assume that it would be applied first to the iPhone and iPod, the application does insinuate that other handheld, rechargeable devices could eventually benefit from the invention.

As if learning about one new aspect of Windows today wasn't enough, a duo of recent patent applications may lend a hand in discovering a few new, um, features about the Windows of the future. Up first is a dubious filing that details an "advertising services architecture" which actually uses content stored on your hard drive to trigger advertisements when browsing the web, and while we're no expert on the matter, that sure reeks of adware to our untrained noses. Next, however, is a glimpse at a potentially updated taskbar function dubbed "clipping lists," which forms clippings of your internet windows, documents, etc. into "peripheral regions of the display." Of course, this idea is certainly not new, but apparently Redmond has a vision in mind that would deviate somewhat from existing creations. 'Course, we're fairly sure you brushed right over that second tidbit as you thought about how violated patent number one would make you feel, no?

Xerox, the same outfit looking to extract information from your web browsing excursions, has now churned out a swank anti-counterfeiting procedure that purportedly allows a vanilla digital printer to "create personalized fluorescent marks on documents." Of course, these fluorescent signatures are commonly used to authenticate currency, and Xerox is hoping that people warm up to the idea of slapping the same level of security onto documents ranging from licenses, certificates, or even personal checks. The method utilizes the "dry ink" found in xerographic printers to create the secure imprint, and curious users can spot the tell-tale sign when exposing the document to ultraviolet light. Of course, you should still be wary of that dubious looking bizhub crammed over in the corner office, but if you're interested in Xerox's latest counterfeit squashing technology, you can snag it as part of the FreeFlow Variable Information Suite 5.0 software.

Just days after hearing that Steve Jobs was indeed looking into the possibility of letting third party applications play nice with his precious iPhone, along comes a suitable patent application that further proves his hesitance to let it happen. Jobs didn't shy away from suggesting that non-native apps aren't usually cellphone-friendly, and a new filing from Cupertino's lair details an "accessory detector" that would "detect whether an external accessory coupled to the connector may interfere with wireless communication with the handheld device." Of course, no direct mention of the iPhone is given, but it sounds like this here invention would alert the user via on-screen messages and flurries of frightening noises if the inserted / installed accessory did not match up with an internally stored "list" of okayed devices. Additionally, the handset would be able to adjust itself on the fly if the add-on did indeed "interfere" with operations, and while no verbiage mentioned any kinds of shut downs or undercover dial-ups to Apple HQ for unauthorized use, there's always the possibility that this type of scrutiny could lead to an easier implementation of a "Made for iPhone" type royalty program.

Looks like the pockets of Qualcomm are going to be about $19.6 million lighter real soon, as a federal jury in Santa Ana, California returned verdicts that found "certain Qualcomm products" infringing on three patents owned by Broadcom Corporation. The lawsuit was originally filed way back in May of 2005 and alleged that five of its patents had been violated, but during the course of the trials, Broadcom ditched one of the claims while the court stayed the case with respect to a second. Notably, none of the patents that were infringed upon were "developed specifically in connection with cellular technology or standards," but the seemingly willful wrongdoing will indeed cost Qualcomm just shy of $20 million -- that is, until a trial judge mulls this thing over and determines if the firm should face any additional financial punishment "based on the finding of willfulness."

Hearing Microsoft's name and "in-car stereo" in the same sentence should elicit any forms of surprise, as we've long since known that Redmond was looking to up the ante of automotive entertainment in a bevy of Ford vehicles later this year. A recent patent was granted to the firm that details a "car stereo including a docking station into which an off-the-shelf handheld computer can be docked," and additionally, it insinuates that a multitude of devices will be supported. Of course, we already knew the iPod would play nice with Sync, and while it doesn't specify if each individual DAP that you cram in this thing will have its own interface to display ID3 tags and the like, it sure seems that the major ones will. Another tidbit is the inclusion of a memory system that will "maintain a record its current state when it is undocked from a particular type of appliance," meaning that when you return and re-dock your handheld, everything should resume without any hassle. Best of all, however, is the insinuation that it won't be limited to just DAPs and PMPs, as "another interface form may allow the user to select from resources such as GPS, internet, a printer over USB, etc."

As if Sony's legal team hasn't dealt with enough this year already, they're getting dialed up yet again for alleged patent infringement, and this time the California-based Target Technology Company is the one pointing the finger. Apparently, the firm is suing several segments of Sony for "deliberately and willfully" infringing on a patent that Target was granted in 2006. The plaintiff claims that products "marketed under the Blu-ray name infringed on a patent for reflective layer materials in optical discs," and more explicitly, "specific types of silver-based alloys with the advantages (but not the price) of gold." The suit was actually filed as an "intellectual property" matter rather than one of chemical imbalances, and while Target Technology is purportedly seeking a "permanent injunction preventing Sony from violating its patent rights in the future, as well as damages with interest," we won't be surprised if a sizable check from Sony's wallet makes this all disappear.

While finding hidden speakers tucked neatly away in one's headrest, rocking chair, or gaming seat isn't exactly surprising, Bose is hoping to integrate the technology one step further by getting "surround sound" into practically every seat imaginable. According to a patent application filed by the company, it's hoping to develop an audio system that includes an "electroacoustical transducer mounted in the back of a seat" so that surround sound is radiated and focused around the ears of the listener. Obviously, said technology could be placed into cars, recliners, office chairs, and beach loungers with relative ease, and while musical entertainment is clearly the primary candidate for use in such a system, the filing also mentions possible telephone integration. Unsurprisingly, Bose didn't mention any details surrounding RMS ratings, frequency ranges, or driver sizes.

Aw snap. Just when you thought the Microsoft / open-source relationship was getting bad, it's now getting even worse, as yet another turn has been taken in the on-again, off-again love affair between the two. Soon after Microsoft's General Counsel claimed that free and open-source software (FOSS) -- a bundle of which related to Linux -- violated precisely 235 of its patents, Linus Torvalds decided to fire back on behalf of the little guy. In an interview with InformationWeek, Mr. Torvalds retorted by suggesting that it is actually "a lot more likely that Microsoft violates patents than Linux does," and even noted that if "the source code for Windows could be subjected to the same critical review that Linux has been, Microsoft would find itself in violation of patents held by other companies." Of course, he backed his statements by stating that the "fundamental stuff was done about half a century ago and has long, long since lost any patent protection," and closed things up by insinuating that Redmond should put its cards on the table so that Linux users prove 'em wrong, or better yet, "code around whatever silly things they claim." As if you couldn't tell, them's fightin' words, folks.

While we knew the Brits were looking Apple's way to help curb the nagging gadget theft problems still going on across the pond, it looks like Cupertino may have the ability to offer up a few solutions after a 2004 patent filing was reportedly awarded. According to AppleInsider, a US patent around "acceleration-based theft detection system" for movable devices was granted to Jobs & Co., and while we're still taking this with a grain of salt, it's not too surprising to hear of Apple coming out with a more secure method to stop theft than that cutesy combination lock built into new iPods. The filing insinuates that an accelerometer could be paired up with recognition software that could theoretically differentiate between normal bumps and ill intentions, and while specific hardware wasn't exactly covered, we can certainly assume that the more portable devices would get the anti-theft treatment first. All in all, the concept here seems fairly novel, but considering that using your Nike + iPod kit would probably cause all sorts of false alarms to go off using such a deterrent, we'll probably stick with the "toss gadget at larcenists' forehead" approach to keep our handhelds secure for now.

We know, it's rather disappointing to check the local forecast on your Melitta MS1MSB or Wii weather channel, only to find the conditions completely not as you expected once you stroll outside, but those guesstimates could be getting a bit of help from weather tracking airplanes. Boeing has filed a patent application that would "using airborne radars to measure wind vectors," essentially strapping weather-sensing nodes onto an airplane so that it collects real-time data whilst passing across remote regions of the planet that typically get ignored. Better yet, the data could even be cross-referenced with nearby planes in order to estimate the best actual forecast for a given region based on numerous information sources, potentially yielding a more accurate look at forthcoming weather. Of course, all logic here would point to humanoid meteorologists being established to interpret and disseminate the information, but until all this gets real, we'll be playin' it safe with the weather forecasting umbrella.
