About this 3D model

This Saftey Bracelet is used for people going out on water, or swimming. It uses three different sensors, the heart rate monitor, the blood to body ratio monitior, and the water pressure sensor. There is also a inflatable life ring compressed within the tube that will activate if and only if, one of either the heart rate or blood sensor goes off, then it will calulate the amount of water pressure above you and inflate the ring accordingly.
