Careful with that rubber duck: you might trigger a call to the paramedics.
The National Institute of Longevity Sciences in Japan says a laser embedded in
the ceiling of your bathroom could raise the alarm if you have a seizure or fall
in the bath. By bouncing a light beam off the water, a team led by Kazuki
Nakajima detected waves produced in the water by respiration and heart rate.
鈥淭he system could detect if you stop breathing and raise the alarm,鈥 he says.
Not everyone is impressed: 鈥淭his probably isn鈥檛 the way you鈥檇 do it,鈥 says Dave
Delpy of University College Dublin. 鈥淚t sounds like overkill.鈥
