Implant can help sleep apnea patients not frighten their partners
CPAP masks are uncomfortable, unattractive, but are sadly necessary for many to live through a night. The implant works by electronically stimulating the nerve, and causing the passage that respiratory passage to open again, allowing the person to breathe. The implant is placed in the patients neck, and then controlled by an external programming device. It also requires charging, since the implant is applying an electrical current.
Now I wonder if you can run Linux on the implant. Maybe Moblin?
