DESCRIZIONE
An autonomous lifebuoy comprising of a body (1), a power supply unit (5) consisting of water-activated electric batteries and water propellers (2) which use the camera image of the closest smartphone to direct the lifebuoy towards the MOB. The Control unit (3) connects to the local area network and nearby smartphones. The invention is also equipped with a non-volatile memory in which an image of the lifebuoy itself and a MOB is pre-recorded, a GPU for comparing the pre-recorded image with the images obtained from the cameras of nearby smartphones, a microprocessor for calculation and issuing of commands to the water propellers.
Other pre-recorded information within the memory of the Control Unit (3) is:
- A human voice pronouncing the word "help" in many languages;
- Different kinds of marine noises;
- Sonar profile of underwater motion of a MOB.
The Control Unit (3) is wired to both water propellers (2) and the power supply unit (5).
In a MOB situation, when the victim is conscious of the surface of his water, the autonomous lifebuoy is thrown into the water (1).
The water activates the battery (5). It powers the Control Unit (3).
The sonar positioner (4) detects human body motions and position information and transmits it to the Control Unit (3) which controls the water propellers (2) to move the lifebuoy (1) automatically to the MOB. [Image Omitted]
