Definitions

  • the present invention relates to a device and method for the rescue of people in aquatic environments that has sensitive characteristics of novelty and inventive activity.
  • the rescue device object of the present invention is intended for application in boats, preferably in small vessels of the type called sports, whose use has been spreading in recent years among large masses of sports and pleasure nautical enthusiasts in all the countries .
  • the present invention has been precisely designed to solve the aforementioned inconveniences, especially in small vessels, resulting in a quick and efficient search for the shipwrecked person by the vessel itself that has lost it, in a minimum time between the moment of the fall to the water of the lost crew member and the moment in which it is known in the boat itself, allowing to perform the classic maneuvers of fast turn to try to recover the castaway in a minimum time.
  • the present invention provides for the realization of a device that allows the crew member to fall in the water immediately, by activating one or more optical and / or sound detectors that allow alert immediately about said event.
  • the present invention also extends to the method by which the device object thereof can be used for the complete rescue operation of a crew member who has fallen into the water.
  • the device object of the present invention has essentially a set of two elements, transmitter and receiver, the first of which is a device that emits a radio frequency signal when activated voluntarily or automatically by contact with the water, said device must be carried permanently by each crew member of the vessel as an incorporated part of their clothing or by means of a collar, adhesive band or otherwise added or applied to the garments themselves, said first emitting element being combined with the second receiving element, tuned to the same wavelength as the emitter, incorporated in the appropriate strategic locations of the vessel itself and combined with an optical, auditory or other type warning device.
  • the emitting element of the device will entail its own independent source of voltage within a completely sealed body that will externally only present terminals of the internal electrical circuit that will remain normally open, closing, however, by the liquid immersion medium that may be water from the sea, from a river course, lake, etc., taking advantage of the effect of dissolving salts in the water, which make it a conductor of electricity, even with reduced tensions between electrodes Eventually, a button will also be provided for the possible manual operation of the device by the crew member fallen into the water.
  • the essentiality of the device object of the present invention will be based on the arrangement of the two assemblies coupled through radio frequency waves, one of which is a collector and emitter to be supported by the crew member and the other receiver to be arranged in the desired point of the vessel, for example, in an area close to the pilot of the vessel, being combined so that at the time of closing the circuit between the electrodes of the pickup and emitter element, the electromagnetic radiation emitted by the first and captured by the The receiver is transformed into a strong optical and / or audible signal that allows to start the rescue maneuvers.
  • the emitting device will therefore comprise an electric and electronic circuit that, powered by its own voltage source, will put two electrodes external to the body of the device, being capable of producing an electric current by closing said contacts through the liquid medium in which the transmitter will be immersed, possessing means to amplify the current generated in the circuit in order to activate the radio frequency generator.
  • the electrical circuit that keeps the pick-up electrodes under a certain voltage can also be closed optionally by means of a manual switch that can be operated by means of an external or internal button that can be activated as one of the faces of the element envelope is flexible.
  • the device itself will activate a microprocessor intended to control auxiliary functions of the transmitter such as: time interval between the closing of the electrode contacts and the generation of the radiofrequency signal (to avoid false alarms caused by sporadic contact with wet surfaces on deck) eventual generation of a test signal simply for checking the good operating state, with a reduced duration, for example less than two seconds and in any case less than a predetermined threshold time and an effective alarm signal in case of immersion or manual operation of the device and others.
  • said enclosure will include a pilot light indicating the state of charge of the power battery, etc.
  • the procedure for using this safety device will involve: a) detachable coupling of the pickup and emitter element in the body of the crew; b) fixed coupling of the receiving element in the vessel in which the crew member is embarked; c) detect the closing of the external contacts of the emitting sensor element; d) measure the time during which the contacts of the emitting element are closed; e) emit a first radio frequency distinctive signal in case the contact closing time is less than a predetermined threshold time; f) emit a second radio signal other than the first in the event that the closing time of the transmitter contacts exceeds the predetermined threshold time; g) to capture in the receiver element the radio signals emitted by the emitting element and; h) issue an alarm, system check signal in case the radio signal has a duration of less than a predetermined threshold time; i) issue an effective alarm signal in the event that the duration of the radio signal exceeds the predetermined threshold time.
  • Non-radiofrequency signals in the event that the contact closing time is less than a predetermined or greater threshold time, may be distinguished by the duration, continuous or intermittent character or other characteristics that allow their distinction and also the test alarm or effective alarm signals can be distinguished, for example, by the duration, by the type of the alarm, by the power of the alarm, etc., that is, all those means that allow distinguishing a signal from verification, whose sole mission is to determine that the system is in good working condition, of an effective signal, whose mission is to capture the attention of the pilot of the vessel or other crew of the same before the emergency situation caused by a crewman's fall into the water.
  • the present invention also provides for the discrimination of the signals emitted towards the receiver in three different types of signals corresponding to: bilge of the boat, fall of man to the water in the case of "captain” or “lone navigator” and fall of man to the water in the case of a member of the crew.
  • the objective of this is to enable the device to control different types of maneuvers according to the different cases.
  • the detection of water in the bilge is added by means of a fixed detector installed in it, both giving rise to external indicating or alarm signals that can be equal or different to indicate the event of different nature that could have taken place.
  • the maneuvers to be executed are different, since the generation of an alarm signal is not enough, but it is done a more complete maneuver is required that provides for the engine to stop, generating a signal to the autopilot to take charge of the control of the course of the boat and a turn signal, all of which would give the captain or lone navigator a chance recover the boat, because it is in the vicinity of the place where the fall to the water has occurred.
