Abstract

A warning system is provided, which is particularly useful as a person overboard warning system. The system comprises a trigger part, worn by a crew member, which emits a signal on immersion in water. This is received by a receiver part on the vessel and automatically causes a transmitter part, also on the vessel, to send a further warning signal to one or more other locations remote from the vessel. These remote locations may be other vessels or land based sites, for instance operated by the coastguard or other rescue agencies. The automatic nature of the onward transmission of the signal received by the vessel makes the system particularly suited to single handed sailors.

Claims

1-32. -32. (canceled)

33. A warning system, the system comprising:

a trigger part;

a receiver part; and

a transmitter part;

the system being provided at a first location, wherein the trigger part is physically separate from the receiver part and the transmitter part, wherein the trigger part has a signal emitter to provide a signal to the receiver part upon immersion in water, the receiver part receiving signals from the trigger part and providing a further signal to the transmitter part to automatically cause a further warning signal to be emitted by the system, the further warning signal being sent to at least one other location.

34. A system according to claim 33 in which the further signal from the receiver part to the transmitter part includes information on at least one of the trigger part'"'"'s identity and the trigger part'"'"'s position.

35. A system according to claim 33 in which the further signal is automatically provided to the transmitter part.

36. A system according to claim 33 in which the receiver part is provided on a vessel.

37. A system according to claim 33 in which the further warning signal includes at least one of the vessel'"'"'s position and the vessel'"'"'s identity.

38. A system according to claim 33 in which the further warning signal includes information on at least one of the trigger part'"'"'s identity and the trigger part'"'"'s position.

39. A system according to claim 33 in which the further warning signal includes a vessel in distress signal.

40. A system according to claim 33 in which the further warning signal is detectably at least 50 km from the first location.

41. A system according to claim 33 in which the at least one other locations include at least one location operated by or for authorities that provides rescue assistance to at least one of vessels and persons, and coordinate such rescue activities.

42. A system according to claim 41 in which the at least one location operated by or for authorities includes at least one other vessel.

43. A system according to claim 33 in which the transmitter part is manually triggered and sends a further warning signal, a manually triggered further warning signal.

44. A system according to claim 43 in which the manually triggered further warning signal is a vessel in distress signal.

45. A system according to claim 44 in which the transmitter part provides for the selection of at least one distress signal from a set of different distresses included in the manually triggered further warning signal.

47. A system according to claim 33 in which the system includes a plurality of trigger parts which are separate from one another.

48. A system according to claim 33 in which the trigger part includes at least one of a light, an electroluminescent light, a power source, a battery, a manual trigger, and an immersion sensor.

49. A system according to claim 33 in which the trigger part includes an instrument for determining the trigger part'"'"'s position.

50. A system according to claim 49 in which the instrument is part of a satellite based GPS system.

51. A system according to claim 33 in which the receiver part includes at least one of a visual alarm activated when it receives a signal from a trigger part, an audible alarm activated when it receives a signal from a trigger part, and a directionally sensitive trigger part signal detector.

52. A system according to claim 33 in which the receiver part indicates the direction of a trigger part providing the signal.

46. A system according to claim 46 in which the trigger part is coupled to at least one of an item of clothing, a life jacket, and a life raft.

53. A method of providing further warning signal, the method including:

providing a warning system, the system comprising;

a trigger part;

a receiver part; and

a transmitter part;

the system being provided at a first location, wherein the trigger part is physically separate from the receiver part and transmitter part;

providing a signal from a signal emitter in the trigger part to the receiver part upon immersion in water of the trigger part;

providing a further signal to the transmitter part to automatically cause a further warning signal to be emitted by the system, the further warning signal being sent to at least one other location when the receiver part receives the signal from the trigger part.

54. A method according to claim 53 in which the method provides a person overboard warning system.

55. A method according to claim 53 in which the first location is a water borne vessel.

56. A method according to claims 55 in which at least one person on the water borne vessel is provided with trigger parts.

57. A method according to claims 53 in which the further signal from the receiver part to the transmitter part includes at least one of information on the trigger part'"'"'s identity and the trigger part'"'"'s position.

58. A method according to claims 53 in which the further signal is automatically provided to the transmitter part.

59. A method according to claims 53 in which the further warning signal includes at least one of the vessel'"'"'s position and the vessel'"'"'s identity.

60. A method according to claims 53 in which the further warning signal includes information on at least one of the trigger part'"'"'s identity and the trigger part'"'"'s position.

61. A method according to claims 53 in which the further warning signal includes a vessel in distress signal.

62. A method according to claims 53 in which the further warning signal is detectable at least 50 km from the first location.

63. A method according to claims 53 in which the at least one other locations includes a location operated by or for authorities that provide rescue assistance to at least one of vessels and persons, and coordinate such rescue activities.

64. A method according to claims 53 in which the at least one other locations include at least one other vessels.
