Patent ID: 7259682

Claim:
System for monitoring live beings, which combines zone and water alarming, including an alarm unit to be arranged on a being's body and a portable alarm centre handled by a person that monitors the being, wherein the alarm unit includes a sender for continuous wireless transfer of intermittent signals on a first channel and transfer of an arbitrary type of signal on another channel, and wherein the alarm centre receives signals sent from both channels for status monitoring of the alarm unit, wherein an alarm device in the alarm centre triggers alarms if the intermittent signal differs from a predetermined intermittent signal state; a water sensor in the alarm unit triggers the alarm unit to send the arbitrary type of signal on the second channel on contact with a predetermined quantity of water; switches in the alarm unit turning off signalling on the first channel when the arbitrary type of signal is sent to the alarm centre; and wherein a normal state for monitoring within a distance zone from the alarm centre is when the intermittent signal is in said predetermined signal state, and wherein the risk of a drowning accident exists when the arbitrary type of signal is emitted on the second channel, wherein a drowning accident alarm is activated in the alarm centre, and wherein the switch turns off the intermittent signal, which means that the system has raised the alarm twice for a drowning accident through the prevailing signal state on both channels, and a third drowning accident alarm is achieved in that the signal on the second channel does not reach the alarm centre when the alarm unit is located at a sufficiently great depth of water.
