Method and system for detecting a danger of drowning

Abstract

Method and system for detecting danger of drowning for a person in water. The method may comprise: determining whether the person is located in the water, measuring the pulse of the person, determining the position of the person, monitoring the capacity of an energy source on the person, transferring data from the person to a receiver on exceeding a boundary value of a pre-determined parameter, a gas chamber on the person is filled with gas and thereby buoyancy is generated, as well as optionally activating an alarm in the receiver. The method may further comprise measuring breathing frequency of the person, measuring pressure at the water depth of the person, measuring body position of the person, and comparing boundary value data and generated data to each other in an evaluation/signal unit as well as when the gas chamber is filled with gas and/or the alarm is activated.
