Redesign a PASS (Personal Alert Safety System) for the fire departments by integrating the circuit to the inside of the firefighter’s coat. The PASS device usually consists of an accelerometer to determine if the firefighter is still moving and an O2 sensor to detect the remaining level of oxygen in the firefighter’s tank. Using flex potentiometers, you could integrate the inputs from the potentiometers and the accelerometer to minimize the false alarms caused by what the PASS device considers to be inactivity. Since the circuit would be mounted to the inside of the firefighter’s coat, the components would be less exposed to water or heat.
