  1. Instrumented Football Helmet Packaging Specifications and Design

  2. Introduction: An update Just a few changes … More accelerometers… it takes 3 points to form a plane, so we should use (at least) three accelerometers to accurately measure acceleration and rotation. New microcontroller… PIC18F45K20 gives us more program memory, 14 ATD channels, and great power management features while only consuming around 20 µA of current.

  3. MUST BE…. • Lightweight • Small (flexible?) • Thermal Restrictions • Hidden • Sturdy Introduction… Will need to fit a microcontroller, 3 accelerometers, wireless adapter, antenna, memory card reader, batteries, charge management, and wires into a small, enclosed space that must be durable enough to survive 35 mph car wrecks…repeatedly.

  4. Product #1: Riddell Revolution IQ HITS™ Positive Aspects: No visible antenna No exposed circuitry Adds negligible weight Negative Aspects: • None (it shouldn’t look or feel different from a normal football helmet)

  5. Ideas Gained: • Multiple PCBs • Placement of antenna Unique to Us: • Memory Card Reader Product #1: Riddell Revolution IQ HITS™ Ideas gained from this product

  6. Accelerometers and sensors measure tilt, acceleration, and vibrations. They influence traction control, airbag deployment, and navigation systems. Product #2:BMW M5 Positive Aspects: Seamlessly integrated Negative Aspects: • Affects/Hinders Performance
