  2. Introduction • Instrumented Football helmet • Features • Concussion Detection (rated in g) • Wireless Communication + Embedded Server • Battery Indicator + Recharger • Removable memory card • Dual Assignment with the Villanova Team

  3. Circular Diagram

  4. Design Constraints • Weight • Size • Power • Wireless Capability • Sensitivity

  5. Accelerometers • Measurement Specialists Inc (MSP1004-nd) • 4.5V • 3 axis, +/- 250g • Concerned with Availability • Analog Devices (ADXL193) – single axis • 6V • +/- 250g • Is Available

  6. Wireless Adaptors • LANTRONIX • WiPort • Matchport – Cheaper, Flexibility with Antenna Both are basically the same same voltage required same interface (serial to 802.11b/g) power consumption embedded servers Only difference we found was price

  7. Microprocessors • Atmel • ATmega8 • 23 i/o • 1k flash • 6-8 ATD • CoridiumARMexpress LITE DIP Module • 16i/o • 32k flash • 6 ATD • PIC • PIC16 family • 8-64 I/o • 0-12 ATD

  8. Battery Management • Maxim • MAX8856 – used in real world most often! • Li-Ion Battery • LIR1865 2200 mAh • Estimated 5 hours of play time: • 5 * 320 = 1600 mAh 5*473 = 2365 mAh
