    en.wikipedia.org/wiki/Drowning_detection_system

    Active systems are often using a wearable on the swimmer, such as a wristband, that monitors the behaviour and position of the swimmer. If the swimmer is detected to be under water för a certain period, an alarm is triggered and through acoustic underwater communication from the wristband to receivers installed in the pool the alarm is transferred to on-site lifeguards that immediately can ...

  5. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    Optimal detection distance varies and is influenced by camera lens size, resolution, field of view, thermal detection range and sensitivity, leak size, and other factors. The system's layers of filters and immunity to environmental elements, such as snow, ice, rain, fog and glare, contribute to false alarms reduction.

  6. Swimming pool sanitation - Wikipedia

    en.wikipedia.org/wiki/Swimming_pool_sanitation

    Showering before swimming can reduce introduction of contaminants to the pool, and showering again after swimming will help to remove any that may have been picked up by the swimmer. Those with diarrhea or other gastroenteritis illnesses should not swim within 2 weeks of an outbreak, especially children. Cryptosporidium is chlorine resistant. [15]

  7. Leak noise correlator - Wikipedia

    en.wikipedia.org/wiki/Leak_noise_correlator

    A leak noise correlator is an electronic device used for Leak Detection and as a leak locator to find leaks in pressurized water or gas lines.. Typically, microphones or acoustic sound sensors are placed in contact with the pipe, at two or more points, to record the sound emitted by a leak (e.g. a hissing noise) somewhere between the points.
