Researchers get one step closer to all-nanowire sensors
The latest in nanowire research has a crew at the University of California, Berkeley creating the very first integrated circuit "that uses nanowires as both sensors and electronic components." By utilizing a so-called "simple" printing technique, the researchers were able to create a batch of uniform circuits that could one day serve as image sensors. According to Ali Javey, an electrical-engineering professor at the institution, the goal is to "develop all-nanowire sensors" which could be used in a wide array of applications, and the benefit of using 'em is their exceptionally high level of sensitivity. In due time, the gurus would like to make everything on the circuit printable, though we have this strange feeling we won't be seeing any actual results from all of this for years to come.
Audi pilot program tells drivers how to squeeze the lemon
Though we're hesitant to believe something this fantastic could actually be implemented in real life, word on the pavement has it that Audi is currently running a pilot program that informs motorists "how fast to drive to catch a green light." Over in Ingolstadt, Germany, 50 traffic lights have been equipped with sensors that beam information to specially equipped whips; the network of "smart" signals not only "adapts to traffic patterns to deliver optimum light switching," but gives drivers a heads-up in order to get 'em through lights and cut down on idling / pollution / road rage. We can just hear those red light camera appeals now: "But judge, my car told me to do it!"[Image courtesy of NOLA]
GM designing car windshield that does the looking for us
Apparently not everyone at General Motors is toiling away in an attempt to get the Volt ready for its 2010 debut, as another sector of the outfit's R&D division is busy creating a windshield that will, at its core, enable us to stop running stuff over. The futuristic glass would utilize lasers, sensors and cameras in order to help drivers see the road's edge better, recognize obstructions and enhance things ahead of us so we'll theoretically react faster. Truth be told, the device is being designed with older drivers in mind, though we don't see why younger motorists won't benefit all the same. Unfortunately, it sounds as if you'll have to keep those toothpicks in your eyelids for a few more years, but at least we're one step closer to full-on autopilot.
San Francisco to test wireless parking sensors, cause rat races to momentarily open spaces
We dig the idea in theory, we really do, but we can definitely see this causing more harm than good. Starting this fall, San Francisco will begin a trial involving wireless parking sensors in 6,000 of its 24,000 metered spaces, enabling antsy drivers to be alerted via street signs or cellphones when a spot becomes available. Only one problem -- give 50 anxious motorists the same message that a single spot is unoccupied, and you've just created a bona fide mess. Though it'd probably be fun to watch from the sidelines, wouldn't you agree?[Via Core77]
Intel shows off robotic hand with "Pre Touch" object conformation
Robotics have come a long way, but they still often miss that innate, nervous sense of reluctant touch. Intel researchers have achieved something similar with a robotic hand that uses electrolocation to create a robotic hand conform to the shape of an object before interacting with it. Shown at Research@Intel Day, the hand uses fish-like electrolocation to bounce electric fields off of objects and then conform the hand to that shape in real time. They call the dynamic "Pre Touch," and it could prove useful for configuring robotics before they interact with objects without, say, damaging them or missing the interface completely. We've been aware of the technology for some time, but as you can see in the video after the break, Intel finally has something to show, and the results are what can only be described as a strangely nervous robotic hand.
SkinForm Project sees shape-shifting structure get its wiggle on
There's no shame in admitting that shape-shifting creatures are a touch frightening, but we'll go ahead and warn you -- those spooked by petite bots will be utterly terrified by this. The SkinForm Project has arisen from the University of Technology Sydney, and while there aren't any elaborate details available just yet, it's described as an "intelligent pneumatic structure that transforms dynamically in response to socio-physical context." Additionally, it seems to utilize a plethora of sensors and rely on a good bit of software programing in order to become the transforming architecture that it is. If all goes as planned, the initiative will be completed on June 12th, but you can take a look at a number of in-progress videos right down there in the read link below.
Audio Ping Pong lets your ears, noggin do all the work
Just when you think Pong can't be played any other way, yet another creative soul emerges to prove the notion wrong. Mike McCracken has managed to remove all visual aspects of the game yet still maintain the core goal by enabling one's head to make the motions typically assigned to the hands. Essentially, a sound is emitted from the headphones on one side or the other, and the gamer has to tilt his / her head just so until the noise is centered. This back-and-forth sequence speeds up to intensify the challenge, and if you can't manage to keep the ringing front and center, an unpalatable buzzer sounds and a light turns on to alert you of your defeat. Really, it's way more clear how all this works in the video below, so have at it.[Via MAKE]
Microsoft adds twist to handhelds with force-sensing technology
Surely you're not content with just multi-touch and built-in accelerometers, right? Microsoft Research is expecting not, as it's already working towards integrating force-sensing technology that will enable gestures to twist on-screen imagery without crafting UMPCs out of flexible material. Essentially, the gurus behind the idea feel that implementing said tech would "turn an otherwise passive component that just holds the device together into an active input surface." In the future, it's likely that auditory cues would enable users to know when they've applied enough pressure to cause a change, and of course, they expect it to work hand-in-hand with existing human-computer interfaces. Yeah, who needs keypads these days, anyway? [Warning: PDF read link][Via BBC, thanks Joe]
Hovering drone could report for work at Miami-Dade police station
We didn't even flinch when we heard that hovering drones employed by Big Brother were going to work in the UK, but somehow those buggers have managed to wander over to America's east coast. Granted, the pilotless drones -- crafted with good intentions by Honeywell -- that are slated to report in to the Miami-Dade police department aren't exactly the same, but they are expected to be used for similar duties. More specifically, they'll be loosed in order to oversee "urban areas with an eye toward full-fledged employment in crime fighting." According to a department spokesman, the fuzz are only looking to use it in "tactical situations as an extra set of eyes," but don't be shocked to see flashing lights from a vehicle without wheels next time you're rolling (a little too) quick down South Beach.
USB TiltStick opens up new world of accelerometer projects
It's not like the modding community at large hasn't shoved accelerometers within vehicles before, but conjuring up projects that utilize acceleration sensing just got a whole lot easier thanks to the USB TiltStick. Reportedly, the minuscule device features a two axis acceleration sensor and emulates a USB joystick in order to play nice with any USB-equipped host. In particular, a standard PC or Nokia's N810 makes for the perfect comrade, and what you do from there is really only limited by your imagination. Granted, only the DIY veterans in attendance should give this one any serious consideration, but feel free to jump on through the break to catch it interfacing with N810.[Via Internet Tablet Talk]
Nokia trial turns N95s into traffic sensing tools
Sure, we've seen cellphones intermingle with traffic data before, but Nokia's looking to up the ante in a big way by utilizing a large network of GPS-enabled handsets to actually predict traffic patterns and help you avoid congestion before you even leave for that afternoon appointment. In a recent trial involving 100 volunteer drivers (and an equal amount of N95s), the handset maker teamed up with UC Berkeley to test the effectiveness of using a device most people already own (read: cellphones) to beam out traffic data rather than installing permanent sensors in roadways. Eventually, Nokia hopes to expand the experiment to over 1,000 folks, and just in case you privacy junkies can already feel your heart racing, you can rest assured that all "personal identifying information" was stripped before being sent back for analysis.Read - Nokia turns people into traffic sensors Read - Video: Nokia test drives traffic monitoring system
Pocketable gas sensor aims to better understand asthma
Sure, we've got fairly sophisticated methods of curbing asthma attacks, but a new pocketable device could hold the key to unlocking more about the relationship between "asthma symptoms and the air a sufferer breathes." Reportedly, this device could allow researchers to look back after an attack has occurred and see exactly what was happening environmentally beforehand. Gurus at the Georgia Tech Research Institute have already been able to help one individual out, as they discovered a "pollutant pathway" from the volunteer's basement into the living room that was allowing vehicle exhaust and gasoline fumes to infiltrate the house. From here, the creators are hoping to downsize the device even further and make it more sensitive, but we've no idea if the current iteration will ever be used commercially.[Via NewScientist]
Purdue tire design can sense damage, warn driver
Usually you can't tell that there's a problem with one of your tires until you've already swerved off the road and crashed into something stationary, but thanks to a group of scientists from Purdue University, the next generation of wheel wraps may be able to detect problems before you're face-to-face with the base of a telephone pole. Led by Gary Krutz of the school's Electrohydraulic Center, the team was able to produce a multi-layer design that can sense damage or defects anywhere on the tire, and which immediately alerts the driver to danger via an embedded chip. First up to adopt the new tech will likely be race car sponsors, who have a high incentive to protect their expensive investments against flats; unfortunately, this safety improvement for drivers will come at the expense of the nation's rabid NASCAR fans, as the likely decline in crashes will only serve to direct their blood-lust at fellow spectators.

Researchers developing advanced electronic nose
Creating minuscule devices that can mimic olfactory systems is nothing new, but an international team of researchers are reportedly working to improve an existing design by basing it on metal oxide nanowires. Granted, the actual technology is a bit above our noses, er, heads, but according to Dr. Andrei Kolmakov, the team's aim was to "demonstrate the excellent performance of a practical device made by combining bottom-up fabricated SnO2 nanowires / nanobelts as sensing elements with a multi-electrode KAMINA [e-nose] platform." More specifically, these gurus decided to implement a "completely new morphology of the sensing layer" composed of tin oxide nanowires rather than the traditional thin-film sensing element. Not surprisingly, those working on perfecting the device are hoping to one day have it installed in areas where intelligent sensor systems are used, but we wouldn't overlook the possibility of finding these things embedded in shirts of the future for those paranoid about their freshness.[Via Coolest-Gadgets]
FIFA to trial chipped soccer ball in Japan
The referees at the upcoming Club World Cup in Japan will likely be taking a little less flack from the fans if a ball manages to come dangerously close to slipping into the net, as FIFA is deploying a type of "goal-line" technology that more precisely indicates whether debatable shots really crossed the line. At the heart of the system are four sensors that are placed around the goal and a single microchip within the so-called smart-ball; if the ball does indeed cross over the goal line, an encrypted message is instantly beamed out to a referee's watch, leaving no doubt as to whether or not a point should be awarded. Apparently, the system will be widely used at the 2010 World Cup if testing proves successful, but unfortunately, this same technology can't be used to embarrass the multitude of players who will inevitably take a dive in order to draw a card.[Via AFP / Yahoo, image courtesy of FIFA]
DIY'er gets busy with automatic projector calibration
While you may not think a 4+ minute clip involving a monotone narrator, flashes of light and lots of sensors could hold your attention (okay, so maybe that came off a bit more riveting than we'd hoped), we'd bet the one posted after the jump could. The video demonstrates a fairly svelte automatic projector calibration system, which relies on very little hardware (and time) to work its magic. Essentially, the low-cost method utilizes rear-mounted optical fibers wired into light sensors, which can channel gray-coded binary patterns through a USB connection. From there, a PC determines precisely how the projection should be outputted for the target surface to be completely filled with an undistorted image. We know, it's tough to wrap your head around, but all the enlightenment you could ever want (on this subject, anyway) is just a mouse click away. [Warning: PDF read link][Via HackADay]
Oregon Scientific's Weather In Motion clock touts proximity sensor
Just in case you've no real need for a seven-day forecast integrated into your timepiece, Oregon Scientific is hoping to lure you in with its proximity-sensing Weather In Motion clock. This stylish device sports a sexy black frame and an infrared motion sensor that changes the display based on how close / far away you are. When you're at a distance, expect to see the "current time, day and weather forecast displayed in large digits and icons," while walking up on it persuades it to show the "indoor and outdoor temperature readings, while the time and weather forecast icons automatically reduce in size." Furthermore, you can enable an automatic scroll mode that will "smoothly shift the information every five seconds." No word on when shipments will arrive, but it'll cost you $64.99 when it becomes available.[Via Technabob]
NTT DoCoMo looking towards intrabody communications
We've certainly seen instances of intrabody communications at work, but now NTT DoCoMo is looking to join the fun and hopefully tie cellphones into the equation. Apparently, the firm has "various devices" in development that could utilize an "advanced handset" in certain forms of wearable electronics to give users the ability to unlock doors, make payments and exchange data with a friend with a simple touch. The prototype mobile packs a sensor produced by Kaiser Technology Company, and while the current version can only transmit data at 40-kilobytes per second, a speedier flavor is surely on the horizon.

Sensor-laden helmets could measure shock from explosions
While we've seen lots of research revolve around battlefield-ready vests, new sensor-studded helmets could be headed to Iraq in order to "measure the shock from explosive devices." Due to mounting concern and a thirst for knowledge about traumatic brain injury (TBI), the US Army awarded Simbex -- the same company involved with Virginia Tech's data gathering helmets -- a contract to further develop technology for use in combat headgear. Furthermore, the firm hopes to "develop an automatic data-collation system" that could potentially relay information to bases or medics via RFID. It was noted, too, that the Army plans on testing Simbex's design along with "several alternative technologies," and the method that proves most useful could be deployed "as early as December of this year."
Intel researchers give robotic hands more sense
While robotic hands typically have no trouble demolishing objects they grab, Intel researchers are looking to make these stereotypically brawny gizmos a bit more sensitive. The technology, dubbed pre-touch, incorporates sensors into a mechanical hand, which enables it to scan objects before it grabs them and react accordingly. Notably, the goal is to "improve the ability of robots to grasp objects in unstructured human environments," potentially making them more useful in the home.
