Intended Use of Heart Rate

• NORA Smart Sock reads heart rate for sleep tracking, sleep training and other general wellness purposes. Heart rate slows down when baby starts to fall into sleep. Reading the heart rate helps the parents to know how shallow or deep the baby is sleeping, which is very helpful for sleep tracking and training. For example, parents can put the baby down into crib if the heart rate starts to slow down, which is one example of practicing sleep training. The heart rate reading is used in sleep tracking algorithms as well. An example of general wellness is NORA can detect elevated heart rate (in healthy range) in feeding.

• NORA Smart Sock does NOT intended for use in the diagnosis of disease or other conditions or in the cure, mitigation, treatment, or prevention of disease, or to affect the structure or any function of the body.
