Outline
• Project overview• Block diagram• Design challenges• Individual contributions• Project demonstration• Questions / discussion
Project Overview• A child safety-system that prevents parents and
caretakers from accidentally leaving children in vehicles.
• Average number of U.S. child hyperthermia fatalities per year since 1998: 37– 49 so far in 2010 alone (8 since start of project)– Goal is to prevent as many deaths as possible
• System tracks presence of children in safety seats and can control the car’s systems to save the child’s life

Design Challenges• Detection of vehicle state varies widely
across car models from 1996 to 2010.– SWCAN, J1850, ISO9141, etc. supported
• Required simultaneous CAN control, audio playback, vehicle state detection, and wireless monitoring
• Control of vehicle depends on imitation of internal components and keyfob
• Non-linear memory layout
Individual Contributions• Team Leader – Mike Williams• Team Member 2 – Chris Cadwallader• Team Member 3 – Craig Pilcher• Team Member 4 – Andrew Sydelko
Team Leader – Mike Williams• Board and Software Design• Initial Component Selection and Schematic• Soldering (poorly)

Project Demonstration
1. An ability to determine the operating state of the vehicle via the OBD-II port.
2. An ability to determine the presence of a child in a safety seat.
3. An ability to use multiple safety seats in one vehicle.
4. An ability to sound an audible alarm when the ignition is turned off.
5. An ability to interface directly to the internal vehicle CAN.
