The SenTAG Pool Safety Device. Pretty neat idea, a wrist worn depth and motion sensor which transmits an emergency signal if the wearer/swimmer gets into trouble. Best bit is that it doesn’t cost the commercial pool owner that much, around £1 to £4.00 an hour to lease. Good job. [Via Gizmag]
The SenTAG wristband has considerable processing power within that continually monitors depth relative to the surface and several characteristics of motion. There inputs are used within a number of interlocking ‘rules’ and related to time….Any breaking of the rules first alerts the wearer by sound and high intensity LED’s. If they do not return to a ‘safer’ situation within a few seconds the unit transmits either an ultrasound and’ or radio frequency alert to the pool supervisor and beyond.
