This invention describes a system that tracks a person's body position, particularly their abdominal orientation. It identifies risky positions, calculates how long someone has been in them, and warns them if they stay in a risky position for too long. The claims narrow this to preventing supine sleep in COVID patients, specifically alerting them if they lie on their back for over five minutes, or on their side for more than two hours.
Why it matters: Filed in 2020, the technology for accurate, continuous body position monitoring has become more accessible and integrated into consumer wearables since then, making such a device more feasible.
