The five-micron LWIR camera being developed by DARPA to provide individual soldiers with t...

With their ability to pick out humans by their heat signatures, long-wave infrared (LWIR) thermal imaging cameras are a valuable asset for soldiers – and alien predators. Unfortunately, non-alien built ones are expensive and so large that they need to be mounted on vehicles. In an effort to make a LWIR camera cheap and small enough for an individual soldier to carry, DARPA is working on a five-micron camera that offers a reduced size without sacrificing performance.  Read More

Artist's conception of WISE J1049-5319, with the brightly shining Sun 6.5 light years away...

In a day when we have examined astronomical objects shining forth from a time shortly after the Big Bang, one would think astronomers have a pretty good handle on what is in the immediate vicinity of the Solar System. That's why the recent report of a binary star lying only 6.5 light-years away came as rather a surprise to the astronomical community. The pair, called WISE J1049-5319 A and B, are brown dwarf stars and only two star systems – the triple star Alpha Centauri, and Barnard's Star – lie closer to our Sun.  Read More

One of Duke University's infrared detector-equipped test subjects

Quite often, when we hear about brain-machine interfaces, it’s in the context of returning an ability to people who lack it. People who are unable to speak, for instance, might be able to interface with a machine that could speak for them. Recently, however, scientists at Duke University used such an interface to augment rats with a sort of “sixth sense” – the ability to detect invisible infrared light by sense of touch. The research could have significant implications for the disabled.  Read More

Air Hogs' AtmoSphere helicopter

There are plenty of remote-control micro helicopters that are operated via a smartphone app or a dedicated control unit, and even one that’s controlled by the user’s brain, but Air Hogs has come up with yet another approach. The company’s soon-to-be-released AtmoSphere chopper moves in response to the proximity of the user’s hand.  Read More

A little over two years ago, we looked at a hand-held device known as the Infrascanner Model 1000, which uses near infra-red light to detect traumatic brain injuries. Now, the InfraScan company has received US Food and Drug Administration approval to market the 1000’s improved successor, the Infrascanner Model 2000.  Read More

GravitySpace recognizes people and objects based on the pressure imprints they leave on th...

Smart floors could soon be part of our smart homes. Scientists in Germany have developed a high-resolution pressure-sensitive floor that can accurately keep track of people and furniture in rooms. Dubbed "Gravity Space," the floor can detect poses, movements and collisions and create a mirror-like inverse projection of the goings-on above. The technology could have a wide range of applications ranging from home security and automation to interactive gaming.  Read More

Toyota's F 'Ciel' Vitz is one of the models using Asahi's new tempered glass, that offers ...

As prolonged exposure to sunlight increasingly becomes a health hazard, causing skin problems and even cancer, automakers have started to incorporate glass that blocks harmful ultraviolet light. Japan's Asahi Glass Co (AGC) has added to its portfolio a new line of tempered front window glass called UV Verre Premium Cool on, which it says is the first of its kind to block about 99 percent of ultraviolet radiation, along with infrared (IR) rays.  Read More

DoorBot streams video and audio to your smartphone or tablet, wherever you are

Everyone wants to feel safe in their home, and it's easier to do so when you know who’s standing outside. DoorBot aims to help with exactly this, by functioning as a Wi-Fi-connected doorbell that streams live video and audio directly to your smartphone of choice whether you’re sitting on your couch or backpacking abroad.  Read More

Harvard Professor of Applied Physics Federico Capasso and his collaborators have invented a nearly perfect optical absorber. By coating a piece of sapphire with an exceedingly thin (180 nm) layer of vanadium dioxide (VO2), a surface is created that absorbs 99.75 percent of infrared light with a wavelength of 11.6 micron wavelength. Such optical absorbers can be tailored to enable a wide range of applications.  Read More

The Satechi Universal Remote turns an iOS device into a universal remote control

Having already provided a remote for the control of iOS devices with its BT Media Remote, Satechi has reversed things by releasing a dongle that turns an iOS device into a universal remote control. In combination with a free app, the Universal Remote dongle enables control of devices around the home that use infrared remote controllers.  Read More
