We'll go ahead and state the obvious here: Audiovox claims this thing is made for DIY installations, but we'd highly recommend hiring a professional if you're totally green at this stuff. You know, considering the immense importance of alignment and the like when it comes to a rear-view back-up camera system. Anyways, the wireless ACA250 kit provides drivers with a color camera (110-degree viewing angle), infrared LEDs for night vision and a monitor that can be plugged into an AC adapter or hard-wired. Not too shabby for $129 -- assuming you're up to the task of putting it all together, that is. Full release after the jump.

The recent tornado tragedy in Iowa underscores the necessity to replace our aging NEXRAD detection system, and thankfully, a team of scientists from various universities are already working to find a suitable replacement. The Collaborative Adaptive Sensing of the Atmosphere (CASA) satellite network would theoretically be installed on existing infrastructure, and it would purportedly scan areas more quickly and target the bottom of storms -- something the current system falters at. The so-called "gap filling radars" could be used to scrutinize the regions where NEXRAD radars can't see, and better still, it will likely be able to more accurately predict the storm path in order to more effectively alert those who may be in harm's way. On the downside, said network isn't expected to be implemented and ready for use until 2013, so we wouldn't go converting that basement into a home theater just yet.

What else can we say? The concept here is pure genius, and it totally makes those pricey security systems seem way pointless (okay, slightly less critical). The FakeTV is a strobe that sets up in an occupied room at night and flashes up beams of light. From the inside, we can imagine it looks fairly curious, but from the outside, it gives prospective burglars the idea that someone is actually awake and watching a television program. It promises to produce the effects of "scene changes, fades, swells, flicks, on-screen motion and color changes," just like they were generated by a bona fide set. We can't speak for how well (or not) this thing actually works, but at just $49, we'd say it's a solid buy if you're the paranoid type.

Sure, there's always the airbag-equipped motorcycle, but for those who prefer to power their own two wheel transporters, you're pretty much on your own. The Dutch Cycling Federation has just cranked out a study showing that some 60 lives could be saved each year (though we're not sure if that's worldwide or region-specific) if airbags were installed on the hoods of vehicles. These external safety devices could also slash serious cycling injuries by 1,500 a year, and while you're likely passing this off as completely infeasible, Sweden's own Autoliv has already developed a bag that "inflates from the bottom of the windscreen." Of course, these timid cyclists could just wait until 2010 and strap on a wearable airbag of their own, but where's the fun in that?

Let's face it -- pedestrians are already running amok in major city crosswalks; it's not like we really need to help them hold up the line of traffic any longer while their light is red, is it? All pent up aggression aside, Hanyoung Lee's brilliant Virtual Wall concept could certainly assist the non-hardened tourists cross from one side to another without fear of being flattened. Essentially, the light-formed barrier would keep cars and Earthlings separated while individuals are cleared to walk, and while we aren't sure if bumping into said obstacle would cause tire deflation, engine stall or any other totally tough consequences, we can't imagine it being too effective (or fun, in a devilish way) otherwise.

Infiniti has a knack for keeping technophiles grinning, and just as it did with the G35's in-dash entertainment system, it's bringing geeks even more automotive improvements to keep our minds off of those skyrocketing gas prices. Reportedly, both the 2009 FX35 and FX50 will be available with all-around cameras (you know, like those found on the EX35), Intelligent Cruise Control and Distance Control Assist. The automaker seems particularly proud of that last one, as it claims to be the first in the industry to offer up the tech. Put simply, DCA will assist drivers in releasing the throttle and applying the brakes as needed in stop-and-go / congested traffic, and (obviously) the system stays activated even after the brakes are tapped. Check out the read link for a few more sneak peeks at the forthcoming features.

Mind you, this isn't the first time we've seen garb constructed to withstand vicious knife fights, and apparently a few Japanese streets are becoming just as frightening as some in London. Reportedly created to provide protection against stabbers following an "increasing number of malicious crimes that have victimized children and late-night convenience store clerks," Nihon Uni has developed a t-shirt crafted from "ultrahigh molecular weight polyethylene fiber." Aside from rendering blades useless, the material is also completely machine washable and lightweight; still, the fabric can be penetrated by "sharp points," so it's up to you to steer clear of rooftop archers. Nevertheless, long-sleeved versions can be had this June for ¥22,000 ($221) to ¥59,000 ($593), while the way less protective short-sleeved variety will run you between ¥19,000 ($191) and ¥52,000 ($522).

Rufus Terrill's stocky handmade robot is more than your average drinking buddy -- in fact, the four-foot tall, 300-pound robotic security guard makes it his job to discourage vandals and vagabonds from marring the streets of Atlanta. The inventor is an engineer-turned-bar owner who got tired of drifters and thieves hanging around his business undeterred. Rather than calling in the professionals, he constructed a remote controlled robot that can flash a spotlight, blast out water and resist even the toughest of 40oz. cans that inevitably come its way. Best of all, he can even make the creature talk, and apparently, its array of scare tactics has been fairly effective thus far. Talk about protecting and serving.

We've seen some pretty well equipped helmets in our day, but UMass Amherst student Brycen Spencer seems a touch more interested in safety advancements than integrated speakers. His concoction, dubbed the Wireless Impact Guardian (WIG), looks like your average helmet at first glance, but a quick look inside reveals electronics designed to sense an impact, judge if you're conscious and dial for help if necessary. Essentially, an alarm is triggered upon impact, and if you're not cohesive enough to disable it after 60 seconds, it automatically rings up 911 and beams out your location via GPS so that medical personnel can get moving. Currently, the device is quite a ways from going commercial, but considering that Mr. Spencer has already invested in a provisional patent, we'd say it's well on its way.

Here's an interesting one. Apparently, a team of engineers failed to shut off the automated emergency calling system on a vehicle being used in a crash test facility in Germany, and as you may expect, it wasn't long after the dummies slammed into a wall that medical personnel were arriving on scene. It was reported that this incident was the first of its kind, as members of the Cologne fire brigade rushed out to what they believed was some sort of "massive" automobile accident. The firemen were able to locate the vehicle due to its integrated GPS unit, and while we're sure they were at least slightly confused upon arrival, at least they got to take the fire engine out for a leisurely spin.

NTT DoCoMo is launching a new mobile phone / bracelet combo aimed at helping youngsters stay safe on the mean streets of Japan. The two-part system combines the FOMA F801i phone, which adds safety features like a 100-decibel alarm, high intensity flashing LEDs, and the ability to automatically notify family in the event of an emergency, and a bracelet remote control which communicates with the device. The phone can be set to provide its location to registered parties, and will turn itself on if it has been switched off. Coupled with the phone is the "amulet style" bracelet, which can be used to locate a misplaced phone, lock the handset, or send a message to another phone (if the device and bracelet are out of range for over five minutes). We suspect that for worried and / or nosey parents, this is a dream come true.

Nearly six months after Slippery Rock University introduced a RFID payment system for mobiles at its campus, we've learned that Montclair State University is requiring that all full-time undergraduates carry a school-issued mobile for their own safety. The handsets, which cost some $210 per semester, are already being carried by about 6,000 students, and feature a GPS function that can be activated to ensure campus police are alerted of their location if something goes awry. Aside from being able to send a request for help immediately, the phone will also call for assistance should the feature remain on for longer than a preset length of time. As it stands, the university has yet to see the Rave Guardian technology used in situations other than false alarms, but a 32-member police force is kept on staff in case any future calls prove legitimate.

Yeah, we did a double take upon seeing the above image too, but believe it or not, that car phone is actually a new Bluetooth handsfree system. Developed by Cartel Mobile Solutions, this in-car setup can reportedly be installed into nearly any whip and will connect up with most every BT-enabled handset. From there, it mysteriously warps you back to the 1990s where you can dial on near-Chiclet sized buttons; once the haze clears, it ushers you back to modern day by enabling motorists to chat without holding anything up to their yapper. Users can opt to wire it to their vehicle's sound system or plug in an external speaker, and yes, that display you see does indeed handle Caller ID duties. Unfortunately, no price was readily apparent, but you can bring that 1979 Buick of yours a few years closer to the 21st century by hitting Cartel up for purchasing details.

We've already seen Intelligent Transport Systems discussed ad nauseum when referring to Nissan, but now Toyota is taking the time to demonstrate its latest advancements in vehicle-infrastructure cooperative systems. Put simply, the aforementioned ITS technologies are being tapped to "enable communication between cars and elements of their surroundings in an effort to reduce collisions." Complementing the massive simulator also on display, the automaker was demonstrating its strides in implementing road-to-vehicle, vehicle-to-vehicle and pedestrian-to-vehicle communications, which can warn drivers via audio / visual cues and even slow the vehicle's speed in order to prevent an accident. Sadly, Toyota failed to mention when we'd see these newfangled safety features integrated into civilian rides, but we can't wait to wave such niceties in the face of our insurance companies as we campaign for lower rates.

Simulators similar to the one recently unveiled to the world by Toyota aren't all that uncommon, but this 4.5-meter high pod is "the first to move laterally and has the longest range of 35-meters front to back and 20-meters from right to left." Reportedly, the automaker plans to use its newest toy to "analyze driving characteristics under various conditions such as drunkenness and drowsiness" and subsequently decide what new safety features should be added to its fleet of motorcars. More specifically, the device enables researchers to "conduct driving tests that would be too dangerous to perform in the real world or that require specific driving conditions," and we're pretty sure the 360-degree concave video screen is quite the draw, too. Unfortunately, we have little faith that you'll ever see a tamed version of this here simulator at your local arcade, but one can hope, we suppose.
