This invention describes a system to help people with sleep breathing problems, like snoring or sleep apnea. It uses a machine that delivers positive air pressure through a mask or device worn by the user, similar to a CPAP machine. A sensor in the system specifically detects the user's sleeping position.
Why it matters: Filed before the widespread availability of highly integrated, low-power visual and motion sensors. Modern embedded systems and AI for positional tracking could significantly simplify the sensing component described in the claims, especially for visual position sensing.
