Definitions

  • This invention concerns in general equipment for underwater activities, and refers in particular to a method and a device to signal the presence and guarantee the safety of a person underwater.
  • the conventional signal is a flag visible also at a distance, flying from a support craft or, more often, on a buoy called a "sub marker", and which makes the position of the diver very visible to persons not in the water and to craft in the vicinity who, on seeing such signals, must keep a certain safe distance from them.
  • This invention stems from the necessity to protect the safety of divers and enable them to go underwater in seas or lakes in all tranquillity, even if visibility is poor and where the growing number of engine powered craft may be becoming even more detrimental for the safety of those going in for this kind of activity.
  • the object is reached with a method of signalling the activity of divers to passing craft which foresees the transmission of a radio signal from a transmitter fixed on a means floating in the area where the diver is present, the reception of the radio signal by a receiver tuned in to the transmitter installed on board of each craft and able to establish the distance from the floating means holding the transmitter, and the emission of acoustic and/or source of light of each craft in reply to the signal received from the receiver and showing the distance between the transmitter and receiver.
  • the system besides enabling diving and swimming activities to be carried out in safety, is also a valid help in reducing accidental collision caused by poor visibility or heavy traffic in particular along the sea coats, on lakes and rivers.
  • a floating means 11 such as a buoy to signal diving in progress, with at least on conventional flag 12, and a craft 13 on the surface near the float.
  • a transmitter 14 is installed on the float or pole of the flag, with, for example, a radio frequency, designed to send out a radio signal which can be either continuous or intermittent.
  • the transmitter will be small, waterproof, powered by a battery and including - Fig. 3 - an antenna 15, an on/off switch 16 and visible indicating means, made up, for example, of different coloured pilot lights 17 to inform the user of the level of the charge of the battery, high, medium or low.
  • the battery can be the rechargeable type by connecting up to the mains or to the cigar lighter of a motor vehicle.
  • a receiver 18 for radio signals tuned in to the transmitter 14 and comprising - Fig.4 - an antenna 19 and a control panel 20 including a luminous 21 and/or acoustic 22 signalling devices able to calculate the distance from the transmitter it is in communication with.
  • the relative receiver receives the signal sent by the transmitter thus locating the presence of underwater activity in progress.
  • the luminous signalling device may therefore comprise for example some green, yellow and red pilot lights, respectively indicative of the safety distance, the potential risk distance and the high risk distance.
  • the corresponding yellow warning light can be coupled with an intermittent acoustic warning; whereas in the high risk condition the respective red luminous signal can be associated with a continuous modulated acoustic signal and possibly the emission of a command to automatically switch off the engine of the craft.
  • the transmitter could also be used not only for underwater activities, but also for persons who are in the water for other aquatic activities such as for example, water skiing, windsurf, motor boating, or simply swimming, etc, to signal their presence to every craft moving in the zone and obviously provided with a receiver, the transmitter in this case being attached to an appropriate device, such as a life jacket, a costume or something similar.
