Abstract

A system and method are used for dispatching a rescue flotation device to an individual who has fallen overboard from a ship. A water-activated transmitter is carried or worn by each and every passenger on a given ship. Upon detecting moisture, the transmitter is activated to send a data signal to a radio signal receiver on the ship. The contents of the data signal may be the location and/or coordinates of the victim, as determined by triangulation of the signal, a GPS receiver and/or radar. Upon transmission of the data, a rescue flotation device or vessel is automatically deployed from a portion of the vessel into the water. The rescue device may be dispatched from a portion of the ship nearest to the determined location of the victim, and/or the rescue device may be self-propelled such that it navigates to the approximate location of victim.

Claims

1. A water rescue system comprising:

a plurality of water-activated signal transmitters, each transmitter being on an individual on a ship;

at least one receiver on said ship, said receiver operable to detect a signal transmitted from said transmitters; and

at least one flotation rescue device mounted on said ship, said at least one flotation rescue device having a motor and an independent navigation system, said navigation system directing said flotation rescue device to an activated said transmitter,

wherein, upon receipt by said receiver of a signal transmitted by one of said plurality of water activated-signal transmitters, said at least one flotation rescue device mounted on said ship is automatically deployed.

2. The water rescue system of claim 1, wherein:

said transmitter further comprises a Global Positioning System (GPS) receiver; and

said signal comprises a location of said transmitter based on an output of said GPS receiver.

3. The water rescue system of claim 1, wherein said at least one flotation rescue device further comprises:

a receiver for receiving said signal comprising said location of said transmitter, wherein said navigation system uses said location in navigating to said transmitter.

4. The water rescue system of claim 3, wherein said at least one flotation rescue device is dispatched to a statistically most probable current location of said water-activated transmitter based on a speed and a direction of said ship, and a time between said detection of said signal and said dispatch of said at least one flotation rescue device.

5. The water rescue system of claim 3, wherein said at least one flotation rescue device is dispatched and navigates to a location based a signal strength and a direction of said signal.

6. The water rescue system of claim 1, wherein said signal is detected by satellites and a position of said transmitter is dispatched to a closest ship to said transmitter, wherein said closest ship is selected from a group of ships, each having at least one said flotation rescue device, causing a said flotation rescue device to be dispatched to said location of said transmitter.

7. The water rescue system of claim 1, further comprising at least one receiver mounted at an aft said ship and at least one receive mounted at a bow of said ship, said receivers being in communication such that a location of said transmitter is triangulated based on said signal.

8. The water rescue system of claim 1, wherein an additional flotation rescue device from another ship is directed to said transmitter if said other ship is closer to said transmitter.

9. The water rescue system of claim 1, wherein said flotation rescue device is directed to traverse a known path most recently traveled by said ship as determined by a navigation system of said ship.

10. The water rescue system of claim 1, wherein said at least one flotation rescue device is configured to stop at a location along said known path based on a duration of time during which said transmitter has been activated and a velocity of said ship.

11. A method of rescuing an overboard victim, the method comprising the steps of:

providing a transmitter to a plurality of passengers on a ship, said transmitter operable to be activated when immersed in water;

detecting a signal transmitted by an activated said transmitter;

determining a location of said activated transmitter; and

following said detection of said signal, automatically launching a self-powered locomotive flotation device from said ship, and sending commands to said device, said commands comprising instructions to navigate by way of said self-powered locomotion towards said determined location of said activated transmitter.

12. The method of claim 11, wherein said navigation is automated based on said determining of said location.

13. The method of claim 11, wherein said commands are manually sent by a user remotely controlling said navigation of said self-powered locomotive flotation device towards said location of said activated transmitter.

14. The method of claim 11, wherein said self-powered locomotive flotation device comprises a motor and a navigation system for directing said self-powered locomotive flotation devices towards said location of said activated transmitter.

15. The method of claim 11, wherein:

said transmitter comprises satellite positioning system; and

said step of determining a location of said activated transmitter is carried out using said satellite positioning system.

16. The method of claim 11, further comprising a step of:

determining, upon receiving a signal from said activated transmitter, if a said signal is a false alarm, by detecting if said signal is being sent from a point on said ship.

17. The method of claim 16, wherein said detecting if said signal is being sent from a point on said ship is based on a signal strength of said signal.

18. The method of claim 16, wherein said detecting if said signal is being sent from a point on said ship is based on an elevation of said signal.

19. The method of claim 16, wherein said detecting if said signal is being sent from a point on said ship is based on a comparison of a detected velocity of said signal transmitter to a velocity of said ship.

20. A method of rescuing an overboard victim comprising:

providing a plurality of cards to passengers on a ship, each of said cards having a water-activated, signal-transmitting beacon and wherein each of said cards is a key to at least one room on said ship;

detecting a signal being transmitted from a said beacon;

determining that said signal is being emitted from a location outside of confines of said ship;

determining a direction of said transmission of said signal using a directional antenna employing a direction finding technique;

approximating a distance of said beacon from said ship;

launching a self-powered locomotive flotation device of a plurality of self-powered locomotive flotation devices mounted at varying points on said ship, said self-powered locomotive flotation device determined to be closest of said plurality of said locomotive flotation devices to said beacon; and

directing said self-powered locomotive flotation device towards said beacon using a motor on said rescue device.
