Abstract

The present invention comprises a method and apparatus for identifying a down diver in distress comprising activating automatic inflation means to inflate a tube, activating automatic signal means, to provide sensory indication of a diver in distress, releasing the tube and the signal means away from a diver'"'"'s body, allowing the tube and the signal means to float to the surface of the water and signalling for help with the signal means.

Claims

1. A diver alarm system to be activated under water comprising:

a housing;

a core removably mounted in said housing in a manner which prevents inadvertent removal and sealed in said housing against the ingress of water, wherein said core comprises;

an inflatable tube;

inflation means for automatically inflating said tube when said core is removed from said housing;

horn means; and

power supply means for activating said horn mean; and

orientation means for properly orienting said system in water without reliance on a tether.

2. An apparatus according to claim 1, further comprising attachment means connected to said housing for attaching said apparatus to a diver'"'"'s diving equipment.

3. An apparatus according to claim 1, further comprising pull means for removing said core from said housing.

4. An apparatus according to claim 1, wherein said tube is in the shape of a ring.

5. An apparatus according to claim 1, further comprising light means activated by said power means.

6. An apparatus according to claim 1, further comprising smoke means.

7. An apparatus according to claim 1, further comprising a one-way valve operatively connected to said inflation means and a burst valve operatively connected to said tube.

8. An apparatus according to claim 1, further comprising external valve means for manually inflating said tube.

9. An apparatus according to claim 1, wherein said core is sealed in said housing by at least one O-ring.

10. An apparatus according to claim 9, further comprising cap means removably connected to said housing to further protect said apparatus from accidental activation.

11. An apparatus according to claim 1, further comprising a homing beacon activated by said power means.

12. A method of alerting people on a water'"'"'s surface of a down diver in distress comprising:

removing a core from a water-tight housing under water;

activating automatic inflation means by removal of said core from said housing to inflate a tube;

activating automatic signal means connected to but distinct from said tube, under water, to provide on the surface of the water, sensory indication of a diver in distress;

releasing said tube and said signal means, under water, away from a diver'"'"'s body;

properly orienting said tube and said signal means without the use of a tether;

allowing said tube and said signal means to float to the surface of the water; and

signaling for help with said signal means.

13. A method according to claim 12 wherein said automatic signal means is activated when said core is separated from said housing.

14. A method according to claim 12 wherein said signal means provides an audible signal.

15. A method according to claim 12 wherein said signal means provides a luminescent signal.

16. A method according to claim 12 wherein said signal means provides a smoke signal.

17. A method according to claim 12 wherein said signal means provides an electronic homing signal.

18. A diver emergency alarm device to be activated under water comprising:

a housing;

attachment means connected to said housing providing means to attach said housing to a diver'"'"'s diving equipment;

a core, sealed against the ingress of water in said housing by sealing means and selectively separable from said housing in a manner which presents inadvertent separation, comprising;

support means;

an inflatable tube connected to said support means, wherein a burst valve is operatively connected to said tube to prevent over-inflation of said tube;

inflation means for inflating said tube via a one-way valve;

signal means supported by said support members for providing sensory indication of an emergency;

power means for activating at least a portion of said signal means; and

orientation means for properly orienting said device such that said signal means is located in the atmosphere above the tube, when the device is on the surface of the water.

19. An apparatus according to claim 18 wherein said signal means generates an audible signal.

20. An apparatus according to claim 18 wherein said signal means generates a luminescent signal.

21. An apparatus according to claim 18 wherein said signal means generates an electronic homing signal.

22. An apparatus according to claim 18 wherein said signal means generates at least two of the following kinds of signals:

an audible signal;

a smoke signal;

a luminescent signal; and

/or an electronic homing signal.

23. An apparatus according to claim 18 wherein said signal means generates at least three of the following kinds of signals:

an audible signal;

a smoke signal;

a luminescent signal; and

/or an electronic homing signal.

24. An apparatus according to claim 18 wherein said signal means generates the following kinds of signals:

an audible signal;

a smoke signal;

a luminescent signal; and

an electronic homing signal.
