Research shows Facebook (probably) isn’t listening through your phone

Some people still believe that their phones are listening in to gather data that will inform targeted advertising or compromise their privacy. Facebook has directly denied that its apps are listening in Congressional hearings, but there hasn't been a...

TRAQ quadricopter locates and hones in on radio signal sources (video)

DNP  Traq quadricopter traces radio signals video

Move over, Parrot AR.Drone; there's a new (prototype) quadrocopter in town. For their senior project, electrical engineering students at Northeastern University developed TRAQ, an autonomous aircraft that tracks down the sources of radio transmissions. That functionality comes thanks to a four-element antenna array, and the team envisions such a device being used in disaster, rescue and surveillance situations, where drones could prove faster to respond than us earthbound humans. The next step would be getting multiple aircraft to work together to improve location accuracy. Who doesn't love an imposing swarm of quadrocopters, after all?

vi-RABT improves ankle rehabilitation with virtual reality and robotics

viRABT

We obviously love our gadgets around here. But, as worked up as we get for things with octa-core processors and 4K displays, what really excites us about technology is its ability to improve people's lives. And while having an endless repository of information at your fingertips 24/7 certainly qualifies, we're more interested in the people working to solve real problems. In the basement of the Egan Research Center at Northeastern University, a group of students are toiling away under the watchful eye and guidance of professor Constantinos Mavroidis to build a rather unique device called the Virtually-Interfaced Robotic Ankle and Balance Trainer -- or vi-RABT. For the better part of a year the team has been working on what started life as a Capstone project. The concept began when Dr. Maureen Holden, from the school's physical therapy department, came to the laboratory with a problem: how can we improve the speed and quality of recovery for stroke patients who have lost strength in their ankles and struggle to stay balanced?

Genius.box wants to put a different experiment on your doorstep every month

Geniusbox wants to put a different experiment on your doorstep every month

There are a lot of things you can have delivered to your home on a monthly basis: magazines, hot sauces, underwear and beer are just a few. The second place winner at the Husky Startup Challenge, genius.box, takes that basic concept but replaces the Fruit of the Looms with simple to perform science experiments. Aimed at children between the ages of eight and 12, the projects inside each package teach a basic lesson in science, technology, engineering or math through a hands-on experience. All of the materials needed for each experiment are included, along with a lesson plan, instructions and "factoid" cards with tidbits of interesting trivia, such as the number of elements on the periodic scale.

The two boxes trotted out for demo day by creators Kate Pipa and Shivangi Shah covered the science and technology portions of the STEM equation. One was a kitchen chemistry set for growing crystals and the other a simple electronics kit, based partially around parts of a Snap Circuits set, that has kids building an electromagnet and lighting up an LED. This isn't exactly a return to hardcore chemistry sets of the past (you'll find no radioactive materials or poisons in here), but it's certainly a step in the right direction for an America whose love affair with science is on the rocks. Every four weeks a child would get a whole new educational playset for the target price of $20 a month. Which is quite a bit cheaper than your standard chemistry set or electronics kit. To be kept in the loop as genius.box works to get off the ground, sign up at the more coverage link.

ThermoShield protects your phone in unbearable heat and bone-rattling cold

ThermoShield protects your phone in extreme heat and cold

Rugged phone cases are bountiful. But, while they may offer some additional thermal protection, they're not built for true extremes. For that, you'd need either piles of insulation (too bulky) or some way to control the temperature inside the case. ThermoShield, one of over a dozen student-run companies vying for attention at Northeastern University's Husky Startup Challenge, went the latter route by slipping a Peltier element inside a slim plastic shell. The current prototype was built on a 3D printer and clearly created for an iPhone, but plans for the initial model should be simple enough to port to any handset. A standard watch battery powers the small plate and by controlling the voltage across it you generate either small amounts of heat or produce a slight cooling effect. A simple switch or slider would be used to manually control the flow of electrons. Trekking through the arctic tundra? Simply crank up the heat to keep your phone from freezing to death. Meandering through the Sahara? Take advantage of the Peltier's thermoelectric cooling properties to keep the Gorilla Glass from melting.

According to one of the creators, Hannah Bialic, it wouldn't be terribly difficult to add automatic temperature control. Though, development costs could significantly drive up the price of the ThermoShield. The hardware could all be baked directly into the case itself or an app could be created that would automate everything. Obviously, though, relying on software would limit the case to working with a single device (and let's be realistic, it won't be your beloved Nexus 4). There's no telling when or if you'll actually be able to pick up one of these variable temperature shells, but you can add your name to the mailing list at the more coverage link.

KrystalBoard wants to replace blackboards and whiteboards with liquid crystals

KrystalBoard wants to replace blackboards and whiteboards

If you ask most people, they'd tell you there's nothing wrong with the standard classroom set-up of a blackboard and chalk, or a whiteboard and dry-erase markers. Nicholas DePorzio isn't most people, though. At Northeastern University's Husky Startup Challenge Demo Day, he took home first prize for KrystalBoard, a liquid crystal-based writing board. His early prototype takes a few cues from Boogie Board's line of scratch pads. Functionally, they're almost identical: use a stylus to scratch your message into the panel then, when you're done, simply press a button to erase it. What DePorzio believes sets his creation apart is the ability to scale to much larger sizes. His first prototype, tossed together in just six weeks, certainly has some rough edges (literally, the stand is made from roughly cut cardboard boxes). But, with a different selection of liquid crystal panels, the hope is that high-contrast classroom-sized KrystalBoards are well within his reach.

The first iteration uses a nine-volt battery to force the crystals to reorient themselves and wipe out any missives, but DePorzio is confident that a small solar panel (like the one on your 99-cent calculator) will have more than enough juice to "power" a much larger model. And "power" is a relative term, since technically there's no electricity coursing through the single-crystal panels. The goal is to save time and money by doing away with erasers, chalk, markers and other disposable supplies. The Northeastern student even believes he can get the cost of materials below that of a standard whiteboard or blackboard, but only time will tell on that one. Though, taking home a large novelty check should give the fledgling company a good head start.

RISE:2013 highlights: Kinect rehab, Lego lobsters, 3D printed tech and more

RISE2013 hightlights Kinect rehab, Lego lobsters, 3D printed embedded tech and more

We were excited and honored when the administration at Northeastern University asked us to help judge its RISE:2013 Research, Innovation and Scholarship Expo. The event, held at the physical education center on the school's Boston campus, brings together an incredibly diverse array of research projects covering a impressive number of fields, including physical and life sciences, engineering, humanities, arts & design, computer and information sciences, health sciences, law, business and social sciences.

As you might imagine, scoring works across such a diverse array of concentrations is no easy task. We did, however, manage to pull out a handful of projects that will no doubt be of particular interest to our own readership. The list includes the use of a Kinect camera and PC for physical rehabilitation, the 3D printing of embedded electrical technologies, a Lego set that helps bridge the gap between crustacean and robot and a device that employs an Arduino board and video games to help stroke victims recover motor skills. Check out a video of all of the above just after the break.
