  • Publication number: 20180319472
    Abstract: A regulator first stage for two-stage underwater breathing apparatuses includes a reduction chamber communicating with a high-pressure gas supply through a balance valve, which is influenced by the pressure of the external environment by a balance diaphragm that, by way of a suitable actuator, acts on the valve. The reduction chamber includes one or more medium pressure outlets, having axes parallel to the operating axis of the balance valve. In one configuration, one or more medium pressure outlets are also provided having axes orthogonal to the operating axis of the valve.

  • Publication number: 20180065721
    Abstract: A method for for assessing severity of an underwater dive includes calculating a dive severity index by: (a) determining the gas breathed by the diver; (b) measuring the dive time; (c) determining the depth profile of the dive; (d) calculating a dive severity index based on a function of steps (a), (b) and (c); and (e) assessing severity based on the dive severity index calculated in step (d), wherein the steps (a), (b), (c), (d) and (e) are carried out in real time, at each instant of the dive time of the diver, and step (d) is performed according to the formula: DSI=k1*f(GAS)*f(D)*f(T), where: DSI is the dive severity index, k1 is an arbitrary constant, f(GAS) is a function of the inhaled gas, f(D) is a function of the dive depth, and f(T) is a function of the dive time.

  • Publication number: 20170265599
    Abstract: A device for reversibly connecting together a first element and a second element designed to be alternately connected and disconnected includes a male element, inserted into a female element to move from a mutually disengaged state to a mutually engaged state, and a slider, for actuation/release of the engaged state, which is slidingly engaged by the male element into the female element. The relative movement of the actuation/release slider and the male element is transferred to first releasable locking members of the male element, which cooperate with corresponding second locking members of the female element to move from a stable locked state to a stable unlocked state of the male element by a movement of the slider in the direction of insertion. Furthermore, the male element includes a handle having the slider at least partially and slidingly housed therein.

  • Publication number: 20160198808
    Abstract: A device for releasably connecting a first element with a second element includes a male element connectable to one end of the first element, and a female element connectable to one end of the second element such that the male and female element pass from a disengagement condition to a mutual engagement condition. A slider activates and deactivates engagement and is engaged to the male element such to slide along the axis of insertion of the male element inside the female element. The relative motion between the activation/deactivation slider and the male element is transmitted to first removable locking members, belonging to the male element and cooperating with corresponding second locking members belonging to the female element such to pass from a stable locking condition to a stable release condition of the male and female elements via a movement of the slider along the axis of insertion.

  • Patent number: 7310549
    Abstract: A dive computer that includes heart rate monitoring capability is provided. The heart rate monitoring is accomplished by a belt that fits around the diver's chest, and the information is wirelessly transmitted to the dive computer. The heart rate information may be displayed during and after a dive, and the dive computer may selectively utilize the monitored heart rate information to compensate the decompression algorithm based on workload during the dive. The dive computer can also utilize the monitored heart rate information to compensate the decompression algorithm based on workload on the surface before and/or after the dive for no fly and repetitive dive calculations.
