  • the use of the user's wristband requires the installation of appropriate systems that will receive the alarm signal from the wristband located in water and in other swimming pool areas.
  • the American US20080266118A1 patent filed in 2008 relates to a wristband that monitors the pulse, heart rate, blood oxygen level, peripheral vasoconstriction, body and/or ambient temperature, blood pressure and other parameters of a swimmer.
  • Chinese CN104517410A invention filed in 2015 provides anti-drowning system with some kind of intelligence, including a swimming bracelet, wireless nodes, monitoring terminal and a server, the described swimming bracelet is connected to the server by wireless nodes, the described monitoring terminal is connected to the server, the described swimming bracelet comprises a set of sensors, a warning device, a clock and a radio communication device.
  • Sentag AB offers drowning hazard detection technology that monitors swimmers through sensor bands.
  • the bands developed by the company monitor the depth and duration of a given user's stay under water. In the event of a threat (swimmer is too deep or too long in the water) the bands send a signal that is received by receivers located in the pool and then sent to sirens, light receivers, pagers or walkie-talkies, depending on the configuration and the operator's choice.
  • the Blue Fox Technology system is a solution based on the use of a wristband that monitors the user's behaviour in the swimming pool.
  • the wristband controls the depth at which the user is located and the time of stay at such depth. If the swimmer stays there longer than the time set in the system the alarm signal is sent to the receiver placed under the water on the swimming pool wall.
  • the Blue Fox Control software allows to program the tolerated depth and time spent at a given depth, and to apply this data to the wristband.
  • the programming of the wristbands is done using the factory software. In order to change the settings of a given wristband, it is placed on the adapter and the depth (5 cm - 125 cm) and the time (5 sec. - 95 sec.) at which the alarm is to be triggered can be selected. The point at which the alarm is triggered depends on the system operator's decision.
  • the aim of the invention is to eliminate the imperfections of the existing Solutions by extending the protection to the areas around the swimming pool and eliminating false alarms.
  • the solution according to the invention allows to minimize the occurrence of false alarms thanks to the use of signals coming not only from the depth sensor but also from the SD accelerometer and the pulse oximeter in the analysis of emergency conditions using the artificial intelligence method.
  • the emitted alarm signal depending on the identified water or air environment, is generated as ultrasonic or acoustic, which allows the band system to function in both environments.

  • the method of generating the alarm signal according to the invention consists in the fact that the signal from the pressure gauge controls the selection of the decision-making process depending on the water or air environment, while the decision to trigger a hydroacoustic alarm for the water environment is made on the basis of a combined analysis of the type of movement performed, the depth of immersion and the time spent at such depth, the decision on triggering an acoustic alarm for the air environment is made on the basis of a combined analysis of the type of movements performed as well as the idle time and pulse rate, while the signal from the proximity sensor allows you to generate an alarm signal only if the band is in contact with the user's body.

  • the operation of the system shown in Fig. 1 is as follows: the system of the CS pressure gauge produces a signal determining the pressure value of the air or water environment. This signal is digitized by the AC1 converter and analysed by the PO wristband's processor. If the signal value corresponds to the atmospheric pressure values, the PO decides that the strap is out of the water and applies the appropriate decision rules for detecting a fall outside the swimming pool. Otherwise, i.e. for the aquatic environment, decision rules stored in the memory of the PO suitable for detecting drowning or a drowning hazard condition are used.
  • the A3 three-coordinate accelerometer system produces three-coordinate accelerometer signals which are analysed by the PO to determine the type of motion or lack of it that the user is performing.
  • the CZ proximity sensor system generates a signal that determines whether the wristband is in contact with the user's body. If the wristband is not in contact with the user's body, the wristband's processor does not apply any decision rule and does not generate an alarm signal, as this means that the wristband is not placed on the user's hand. If the wristband is in contact with the user's body, a decision rule stored in the processor's memory that is appropriate for the in water or out of water situation is used, based on the type of movement or its lack situations of falling or drowning is detected.

  • the alarm signal generation system emits an ultrasonic or acoustic signal outside the wristband, propagating in water or air environments, respectively.
