^ TOPGoal
Produce a CAT scan-like view of the interior of a collapsed building to aid disaster rescue. Specifically,
- Provide a 3D view of the collapsed interior indicating the structurally strong support walls and cavities
- Location of survivors
- An error estimate on the reconstruction
Approach
- Sensors are embedded in the building and begin sensing after a collapse
- Acoustic/ultrasonic sensors map out the cavity that each sensor finds itself in
- UWB radios located on the sensors locate other radios and perform locationing as well as material sensing using signal attenuation measurements
- Heartbeat sensors locate survivors in cavities
- All the collected information is transmitted to the surface via energy-efficient paths discovered by the sensors. UWB is used for this communication as well
Lab Setup
- For the picture and description of our lab setup, read "2. What was the UWB measurement setup?" section under FAQ tab.
