  6. PDR Ingredients • Problem Statement • Requirements Analysis • Design Alternatives • Your Solution: Block Diagram • MDR Deliverables

  7. PDR Ingredients • Problem Statement • What is the problem? • How significant is the problem • Context: effect on individuals • Context: effect on groups • Requirements Analysis • Design Alternatives • Your Solution: Block Diagram • MDR Deliverables

  8. Team RCA’s PDR Slide Deck

  9. Concussion Detection in High School Football • Current concussion detection • Train coaches to recognize symptoms • Players may hide or not experience symptoms right away What is the problem?

  10. How significant is the problem? • 1.6 – 3.8 million sports-related concussions in the United states every year • Have reached “epidemic level” • Not only professionals • Young people ages 15 – 24 years • Second leading cause of TBI (Traumatic Brain Injury)

  11. Context: Effect on Individuals • Post Concussion Syndrome • Problems concentrating, irritability, sensitivity to light… • If gone undiagnosed • One hit away from traumatic brain injury • Multiple impacts add up

  12. Context: Effect on Groups • Affects team sports and the way they’re played • “Tough guy attitude” • Creates a culture • Subjective decision making

  13. PDR Ingredients • Problem Statement • Requirements Analysis • Specifications • Inputs and Outputs • Design Alternatives • Your Solution: Block Diagram • MDR Deliverables

  14. Team RCA’s PDR Slide Deck

  15. Requirements Analysis: Specifications • Real-Time continuous impact measurements • Player specific adaptability • Equipment weight increase less than 5% • Effective range 150 m • Responds in under two seconds • Robust • Interference • Durable

  16. Requirements Analysis: Inputs and Outputs • Input • Impact data • Output • Likelihood of concussion • Access to archived impact data

  17. PDR Ingredients • Problem Statement • Requirements Analysis • Design Alternatives • Your Solution: Block Diagram • MDR Deliverables

  18. Design Alternatives • HITS – Head Impact Telemetry System † • Six accelerometers • Frequency, location, and magnitude • Sideline response system • Linear acceleration • †Measuring Head Kinematics in Football: Correlation Between the Head Impact Telemetry System and Hybrid III Headform. Beckwith, Jonathan, Jeffrey Chu, and Richard Greenwald. October 13th 2011

  19. Design Alternatives • ShockBox • Impakt Protective • Commercial use for football/hockey • Secured with high adhesive bonding tape • Wireless transmission • Threshold of 50 g set by app • HEADS • BAE Systems • Military use • Suspended beneath the crown of the helmet • Wireless/USB transmission • Processing done by computer at base

  20. PDR Ingredients • Problem Statement • Requirements Analysis • Design Alternatives • Your Solution: Block Diagram • MDR Deliverables

  21. Our Solution: RCA • Array of sensors in helmet padding • Continuous measurements • Variable impact thresholds • Wireless transmit on threshold trigger • Base station • Database: Impact data & medical history • Concussion algorithm • Wireless transmit to UI & triggered helmet • UI • Android device • Easy to interpret results within two seconds of impact

  22. Our Solution: Block Diagram

  23. PDR Ingredients • Problem Statement • Requirements Analysis • Design Alternatives • Your Solution: Block Diagram • MDR Deliverables

  24. Proposed MDR Deliverables • Demonstration of Impact Data Collection • Accelerometer interfaced with processor • Helmet processor transmission • Demonstration of Base Station/UI Interaction • Using test data • Receive from helmet • Run algorithm • UI able to receive and display test results
