nCamp Stove February 27, 2017

This compact wood-burning camping stove uses fuel that is readily available in forests - sticks, twigs, and other combustible material. By using renewable and readily-available fuel, this stove eliminates packaging/trash associated with canned fuel.

RVS Rubber Solutions February 10, 2017

According to the U.S. Environmental Protection Agency (EPA), about 100 million pounds of tire components discarded during the manufacturing process are dumped in landfills nationally each year because the body ply—the tire’s largest component—can’t be effectively recycled. But RVS Rubber Solutions, a student startup based at Case Western Reserve University, believes it’s come up with a solution to this environmental hazard: new technology called Resonant Vibrational Separation (RVS) that extracts the rubber and steel from within the components in a cost-effective and environmentally friendly way.

Cast Glass Artwork February 7, 2017

Cleveland Institute of Art glass student, Mark Rubelowsky, turned laser cut plywood into a cast glass masterpiece. Using the think[box] laser cutters, he created a multi-layered wood mold lakeside. He used this mold to make a negative out of rubber, which he then used to cast a wax positive identical to the wooden mold. A plaster and silica mold was built around the wax positive, and the wax was steamed out to empty the mold. Then, Mark filled the plaster mold with glass powder and cullet, and fired the piece.

Wireless Low-Power Low-Cost IMU February 2, 2017

Inertial Measurement Units (IMUs) are self-contained systems that measure linear and angular motion, usually with a triad of gyroscopes and triad of accelerometers. IMU's are used in robotics, structural health monitoring, autonomous vehicles, and more. This self-contained IMU prototype uses the MPU9250 sensor package which uses magnetic field and temperature data to compensate for the drift problems typically seen in gyroscopes and accelerometers. Data is packetized by a 32-bit ARM Cortex-M4 microcontroller and transmitted to a desktop computer using the XBee protocol. Compared to commercially-available IMU's, this prototype is low-cost (under $100), low-power (less than 330 mW including the wireless transmitter), and miniature. Research is underway on novel approaches to further minimize sensor drift and improve accuracy.

Reflexion Edge January 24, 2017

The Reflexion Edge is a portable, affordable, and fast concussion screening solution. This prototype was displayed at CES 2017 where over 160 news articles and social media posts reported on it. It is capable of monitoring a host of neurocognitive and psychomotor functions including depth perception, peripheral awareness, balance, complex reaction time, and memory. A user stands in front of the device and interacts with light patterns that appears on the device by touching the integrated touch screens. Data is collected during a thirty second trial that is performed weekly. Deviations from a developed trend line are used to spot potential concussions and pull athletes from play.

CrystalE - Energy Harvesting Sensor Network January 19, 2017

Description: This innovation in hassle-free building sensor networks will allow facilities to implement HVAC and other sensor networks without the up-front cost of wired sensor networks and yet without the recurring cost of batteries conventionally used in these types of systems. A mechanical energy harvester powers an ASIC sensor, both designed by Dr. Phillip Feng's research group. The information and power is fed to an existing ultra low-power 200 microwatt transmitter. The resulting system is cheaper and longer-lasting than competitive products on the market today.

WES Debit Payment System January 19, 2017

WES is a new debit payment system that lets you pay for purchases in under 3 seconds. Compared with traditional credit card procesing systems, this means as many as ten transactions can be processed in the time it usually takes to process just one. In this system, the balance is stored on the WES card to speed up transaction time by avoiding the need for the vendor's transaction terminal to contact a centralized server. An encryption handshake scheme is used to prevent tampering with account balances.

Tubercle Blades for Wind Turbine Efficiency January 19, 2017

Researchers added tubercles to the leading edge of wind turbine blades for a 4.8% increase in lift-to-drag ratio. This increase in performance is expected to translate into increased energy output versus conventional blades. After successful computer simulations, the researchers used the ShopBot CNC table router to machine a fiberglass mold out of machinable wax. These blade prototypes will be tested in a local wind tunnel facility to verify the increased performance seen in simulation.
