    2013ANTsTeam ANT

    Kristin Spera, Ryan Thompson, Allison Tse (Sponsored by V-LINC)

    As part of an ongoing partnership with V-LINC, the team developed a prototype to assist their client with a task many likely take for granted: eating. With limited mobility in her hands and arms, this prototype enabled the client to join her family and eat at the dinner table with minimum assistance. The final prototype consisted of two major components. The first component would push food from a rotating plate to a specialized “plate-spoon,” nicknamed the “ploon.” The second component would raise the ploon up so that the food could be eaten using only the chin and mouth. The team worked intimately with their client to develop this prototype, and have continued researching and designing in 2014.

    Kyle Fitzsimmons, Qais Feroz, Shijit Dasgupta (Sponsored by the JHU Applied Physics Laboratory, Technical Services Division)

    The Johns Hopkins University Applied Physics Lab experienced an issue in one of its buildings when very heavy drums were required on a floor higher than the building’s elevator ran. Lugging the heavy drums up flights of stairs turned out to be incredibly difficult and ultimately too unsafe to do. Team APD developed a custom lift device to facilitate the transport of these 800 pound loads up the stairs. The team’s designs involved an automatic dolly attached to a rigid track that ran the length of the staircase and could maneuver the tight staircase turns.

     

    2013APLsTeam APL

    Andrew Kelly, Tiras Lin, William Shepherdson (Sponsored by the JHU Applied Physics Laboratory)

    Another project from within the JHU Applied Physics Lab, Team APL developed a Schlieren photography system to validate a computational fluid mechanics model for supersonic flow. The system used high pressure tanks to produce supersonic flow in the test section and captured high-resolution images to characterize the flow, all while minimizing vibrations and allowing for the safe discharge of compressed air at supersonic speeds.

     

    Team BAB

    Jeffrey Kamei, Yejin Kim, Anshul Mehra (Sponsored by the JHU Bloomberg School of Public Health, Center for Injury Research & Policy)

    2013BABsPartnered with the JHU Bloomberg School of Public Health, Team BAB developed this prototype, the first version of a vision-based system designed to prevent children from being unintentionally left in hot cars. The system was developed using hardware from Microsoft’s motion-sensing input device, Kinect. Using the Kinect’s infrared and RGB cameras, the system could accurately detect minute motion from within a vehicle. Motion as small as the chest expansion and contraction of a breathing baby could trigger the system’s motion sensors. Since the system used infrared cameras, the system was able to operate without interruption of false-positives from motion outside the vehicle. This research project has been continued in 2014.

     

    2013BACsTeam BAC

    Sarah Dodge, Michael Leibel, Patrick Luckett, Matthew Addis (Sponsored by Baltimore Aircoil Co.)

    As part of an ongoing partnership with Baltimore Aircoil Co., team BAC build a research-scale cooling tower hot water basin to quickly measure the flow distribution from a water nozzle. With their test rig, the team optimized and tested new nozzle designs. Within cooling towers, a common problem is the efficient and complete distribution of hot water over the entire area of the basin. If nozzles do not completely coat the basin, then there is unused area within the tower and the system being cooled will run at lower efficiency. The team’s research provided significant data for the future design of nozzles in cooling towers, which will help improve energy efficiency and reduce carbon footprints.

     

    2013BGEsTeam BGE

    David Leff, Nir Rattner, Yoshitaka Sei (Sponsored by Baltimore Gas & Electric)

    As part of an ongoing partnership with Baltimore Gas & Electric Co., Team BGE developed a vision-based method to classify overhead electrical conductors without de-energizing the system or touching the live conductors. The team’s prototype combined clever optics with a high-resolution digital camera and a set of matching algorithms. The prototype enabled a field engineer to enter a substation with only a tablet and a camera, take pictures of the lines to be classified, and receive instantaneously on the tablet information about the conductors.

     

    Team BRX

    William Crawford, Daniel Fischer, Renata Smith, Benjamin Wasser (Sponsored by the Air Force Research Laboratory)

    2013BRXsAs part of the Air Force Research Lab’s University Design Competition, Team BRX designed a lightweight, portable, inflatable bridge for use by Air Force Special Operations soldiers. The prototype was constructed using composite air beams and was covered in rip-stop nylon. As part of the competition, the team demonstrated the load capacity of the bridge (over 350 pounds at ~16 psi) and ran an obstacle course to show its versatility in the field. The competition also involved an elevation change obstacle. The entire inflatable bridge could fold into a package the size of a backpack for easy transportation. Shown in the picture, two of the team’s members pose on top of the deployed prototype. This was the second of three years that JHU will be entered in the AFRL UDC.

    Andrew Berrodin, Andreas Gubler, Ada Sierraalta (Sponsored by CSA Medical)

    CSA Medical produces a successful cryotherapy product called the TruFreeze. Cryotherapy is used in endoscopic ablation surgery to eradicate tissue inside the body. This project was aimed to explain some behavior seen in the liquid nitrogen flow within the machine, and then to further improve the flow by redesigning the flow path. As part of the project, Team CSA was able to visualize the flow in different sections of the device and eliminate unnecessary components to improve the output of the device.

     

    Team FLU

    Cameron Ahmad, Rick Fenrich, Ted Grunberg, Adam Weiner (Sponsored by the JHU Department of Mechanical Engineering)

    2013FLUsA continuation of the 2011-2012 FLUID team’s project, Team FLU designed, manufactured, tested, and installed a particle image velocimetry (PIV) device for use in a Johns Hopkins Mechanical Engineering undergraduate lab. PIV is an optical method to visualize the flow in or around test sections and is often used in education and research. Small particles in a fluid (typically water) are illuminated using powerful sheets of light while successive photographs are taken of a test section. By taking the photographs in pairs, software can identify and track each particle in the flow in order to develop a visual representation of the flow. With this device, undergraduates in John Hopkins’ fluid mechanics courses will be able to observe and examine real-life fluid motion and apply concepts learned in class. The photo shows the team’s test section with an acrylic airfoil as the test geometry.

    Thomas Ayotte, Kielan Crow, Jennifer Zuza (Sponsored by Ingersoll-Rand, Security Products Division)

    Ingersoll-Rand is a manufacturer of many products and devices encountered on a daily basis, including door locks and security devices. Team LOC was tasked with improving the capabilities of Ingersoll-Rand’s electronic security locks by incorporating stand-alone, regenerating energy sources, allowing for the security system to be completely removed from any electrical grid. The team experimented with many prototypes and technologies, including photovoltaic cells, turbines, and piezo-electrics. The final prototype, shown stripped away in the photo, incorporated many different energy generating components to provide their client with an grid-independent electronic security lock system.

    Bernard Cheng, Noah Dennis, Elyse Edwards (Sponsored by NASA)

    Team STE was tasked with solving the difficult problem of enabling NASA astronauts with little knowledge of internal medicine with the ability to quickly and easily check and record their own vitals. Additionally, the team was faced with the challenge of minimizing error in their measurements despite the noisy environments of spacecraft and space stations. The team developed an electronic stethoscope equipped with headphones and a suction cup which allows operators to check hear their own body sounds while using their hands for other tasks. The final prototype, powered by 4 AA batteries, is shown in the photo.

     

    2013THDsTeam THD

    Kimberly Ashman, David Carasiti, Keith Graeff Jr., Tracey Vill (Sponsored by Turkey Hill Dairy)

    Team THD was tasked with improving the process of transporting and loading heavy rolls of plastic in an ice cream packaging production line. After closely examining the existing process, the team identified areas for improvement and set out to design and implement improved methods. The team’s solution consisted of two parts: an improved cart for efficient transportation of the heavy plastic rolls, and a lift/hoist system for loading the rolls onto the production line. The cart designed by the team was capable of efficiently storing multiple rolls (of varying sizes) horizontally for transportation, but could also swivel so as to reorient the rolls vertically for loading onto the line. Once in the vertical orientation, the rolls are hoisted mechanically onto the production line with minimum physical effort.
