Abstract
Abstract A safety device for locating an individual fallen into the sea includes a visual indicator in the form of a dye and an intermittently operated lamp (3), and a radio transmitter (9) for transmitting a radio signal. The dye is contained in a vessel (4) having a trap door and control circuits (12) are provided having a power source (5) and automatically operated by a water sensitive microswitch (10) to open the trap door of the dye vessel (9), energize the intermittent lamp (3) and energize the radio transmitter (9), all of the components being integral with a helmet (1) worn by the individual. A radio receiver may also be provided on a boat for receiving signals transmitted from the radio device and guiding the boat to the radio device.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
73 words
Safety signalling device for locating an individual fallen into the sea, comprising: visual means comprising an intermittently operated lamp means and a liquid dye means contained in a vessel; radio means for transmitting a radio signal; power and control circuits for operating said visual means and radio means; and a helmet to be worn by said individual, said visual and radio means and said power and control circuits being integral with said helmet.
Claim 2
Dependent Claim
73 words
Safety signalling device for locating an individual fallen into the sea, comprising: visual means comprising an intermittently operated lamp means and a liquid dye means contained in a vessel; radio means for transmitting a radio signal; power and control circuits for operating said visual means and radio means; and a helmet to be worn by said individual, said visual and radio means and said power and control circuits being integral with said helmet.
Claim 3
Dependent Claim
47 words
Device as claimed in claim 1 and further comprising: a boat from which said individual has fallen; a radio receiving means located in the boat for receiving signals from said radio means for driving the boat by motor, rudder and sail unfurling functions to said radio means.
Claim 4
Dependent Claim
24 words
Device as claimed in claim 1 wherein: said power and control circuits are located in a removable casing at the front of said helmet.
Claim 5
Dependent Claim
16 words
Device, as claimed in claim 3, wherein: said power circuits are of the rechargeable battery type.
Claim 6
Dependent Claim
25 words
Device, as claimed in claim 4, wherein: said control circuits further comprise water-sensitive micro-contact means for automatically actuating said control circuits when contacted by water.
Claim 7
Dependent Claim
29 words
Device, as claimed in claim 5, wherein: said control circuits include manually operated switch means in parallel with said micro-contact means for selectively by-passing said micro-contact upon failure thereof.
