This Poseidon Computer System should have been installed in the Kelana Mahkota swimming pool. It might have saved the girl (Bianca Thio Yee Shen) that drowned there on 1 Aug 2005.

A 10-year-old girl has been saved from drowning by a computer system designed to raise the alarm when swimmers get into difficulties. The girl, from Rochdale, was at the deep end of the pool in Bangor, north Wales, when she sank to the bottom.

The £65,000 system, called Poseidon, detected her on the pool floor and sounded the alarm. A lifeguard pulled her out and she recovered in hospital.

It is thought to be the first such rescue in the UK.

The girl had just entered the water and she had swum only a few strokes before appearing to black out.

One of the safety system’s four underwater cameras showed her sinking without any sign of a struggle into the 12ft 6in deep end.

Once she had lain motionless on the pool floor for three seconds, the computer sounded an alarm which also pinpointed which part of the pool the girl was in to the five lifeguards on duty.
