FLIR's second-generation thermal camera now works with (almost) any smartphone
When FLIR launched its first smartphone-based thermal camera at last year's CES, the biggest annoyance people had was that the hardware was baked into an iPhone 5 case. Anyone who wasn't toting Apple's newest two smartphones was understandably aggrieved about that decision. That's why, as a do-over, the company has released a second-generation FLIR One that clips onto the bottom of your smartphone over Lightning or micro-USB, letting Android users in on the fun.
Scientists develop pair of algorithms that could enable thermal cameras to pick out drunk people
We're not sure if Georgia Koukiou and Vassilis Anastassopoulos of the University of Patras in Greece like a tipple or not, but the pair have developed two algorithms that, when used with thermal imaging, could pick out drunk people in crowds. What is it that betrays your best intentions to look sober? As always, your face. Booze causes the blood-vessels in your visage to dilate, and the researchers used this principle to compare facial scans against a database of tipple-free mug shots. Likewise the duo found that when under the influence, the nose gets warmer, while the forehead cools -- another visual check that the infrared can help identify. The hope is that using this technology, law-enforcement can make a judgement call based on more than just your wonky walk. But in our experience, the troublemakers are pretty good at outing themselves.
Modder builds $150 open-source thermal imaging camera to help insulate his house (video)
Modder Andy Rawson thinks he's found the secret to turning smartphones into super-cheap thermal imaging hardware. Inspired by his quest to find leaks in his old home and the high cost of professional gear, he set about building his own. A 64-zone temperature sensor connects to his iPhone via the dock, overlaying the data onto his camera display. He's planning to open-source the $150 hardware, and an Android variant of the hardware is currently in the works -- although details for both are currently thin on the ground, you can see his announcement video after the break.
Researchers working on thermal cloak, Predators trill their disapproval
Slathering yourself with mud to avoid head-hunting aliens is great and all, but it ain't exactly the paragon of good personal hygiene. Fortunately, researchers have concocted a cleaner and less cakey defense against Predators that's more likely to be mom approved. Fresh on the heels of the microwave invisibility project at the University of Texas at Austin, French researchers have found a way to make a cloak that can hide a subject from thermal imaging devices. The concept uses alternating materials with varying rates of diffusion to move heat around and create a thermally invisible region. Conversely, the technique can be used to concentrate heat in one spot so it gets hot rapidly. Although it doesn't quite have the wow factor of Cornell's invisibility project, the thermal research may prove to be more practical because it also can be used to manage heat and improve cooling in components such as computer chips. Of course, the question now is, can it be used to cloak an entire tank?
GE turns butterfly-inspired tech into cheap, accurate thermal sensors (video)
When last we heard from GE and its Morpho-butterfly inspired sensors, all the talk was about detecting chemicals. And, with $6.3 million in funding coming from DARPA, we're not surprised. In the latest issue of Nature Photonics, however, the company's researchers show that the wing-like structures are just as good at detecting heat as they are ricin attacks. By coating them with carbon nanotubes the team was able to create a sensor sensitive to temperature changes as small as 0.02 degrees Celsius with a response rate of 1/40 of a second. The sensors could eventually find their way into imaging devices and medical equipment, and are expected to cost just a fraction of similar technologies currently on the market. Of course, since DARPA is still involved with the project, there are some potential security uses as well -- such as screening devices and fire detection. Head after the break for a video and some PR.
BAE's infrared invisibility cloak makes tanks cold as ice, warm as cows
Warfare's constantly evolving. Daylight battles became late-night duels, and pre-noon skirmishes shifted to sundown slaughters -- some might say we're just getting lazy, but either way, thermal imaging now plays quite the vital role. Now BAE and the FMV -- Sweden's equivalent to DARPA -- have a way to mask the heat signature of heavy machinery. Adaptiv is a wall of 14 centimeter panels that monitor the ambient heat and match it, so it can't be picked out from the background radiation. The tech can also be used to replicate the profiles of other things -- you know, like a spotted calf or a Fiat 500. BAE believes the tech is scaleable for buildings and warships, the only downside being that all future commanders will have to make sure their operations are finished before dawn. Wouldn't want your soldiers to see that five o'clock (AM) shadow, now would we? [Thanks, Rob]
Termibot robot exterminator kills termites, heralds terrifying future
Termites be warned: Australian outfit Termicam is bringing the noise Predator-style with the Termibot, a dual-tread thermal imaging robot designed to eliminate insects. The bot scoots around inside walls and under houses relaying information from its thermal camera and moisture sensors back to an operator, and when termite (or other insect) activity is detected, it uses a probe to smash the nest and inject pesticides directly where they're needed. While we're not certain we need to help robots perfect the techniques they'll use to ferret out the last remnants of the human resistance, we're not too worried yet -- the Termibot is currently tethered to its operator with a long cable. The designer says a fully wireless version is in the works and will be brought to market later this year, however -- it's being held up while the business experiences some growing pains. Termicam also says they're also looking to expand the uses for the bot to other applications where that thermal camera might come in handy, like bomb disposal and search and rescue -- looks like the PackBot's got some competition.[Via Crave]
