Team Aerodyme has created a self-deploying device for the rear of tractor-trailers that stabilizes airflow and cuts drag force by 10%. Unlike other solutions, it requires no effort on the part of the driver. The device has a speed sensor that will engage Aerodyme at highway speeds. When it’s not in use, the device retracts. After initial testing, the team also has started development on an updated design that can be mounted along the sides of a trailer, allowing it to be installed on trailers with roll-up doors. Trucking companies spend upward of $100 billion on fuel every year in the United States, so increasing fuel economy has the potential to save billions of dollars every year and eliminate hundreds of tons of carbon emissions.

For the nearly 5 million Americans suffering from treatment-resistant depression, the drug ketamine has emerged as a powerful option. The drug can be highly addictive, however, so doses must be tightly monitored by doctors. Team Nasolution has created a device that delivers a precise dose of the drug via nasal spray and can be remotely monitored by healthcare providers. That means patients don’t have to go to their doctor’s office for treatment, which is currently the standard practice. The device measures a precise dose and makes it available at the appropriate time from a tamper-proof vial. Wireless connections allow doctors to remotely monitor patient compliance. The device also shows potential for other medicines delivered via nasal sprays, a fast-growing segment of the pharmaceutical industry.

Students work everywhere: Coffee shops, the library, almost anywhere there’s a seat and a power outlet. Truth is, lots of professionals do the same. But what to do when they need a refill or a bathroom break? The choice often is to ask a nearby stranger to keep an eye on their laptop and other belongings or pack up and hope they can find a spot when they return. Team Watchdog’s solution is a small device that sits atop those belongings. If it’s disturbed, the hockey puck-sized device will emit a loud alarm, drawing attention to the would-be thief. Users activate and deactivate Watchdog with a simple radio-frequency identification fob they can keep on their keychain.
