Benefits of technology

"The present invention provides methods and devices for rescuing a diver in distress. The device includes an air pressure sensor, an electronic controller, a power source, and at least one response element. The sensor measures air pressure in the diver's breathing system and sends signals to the controller. The controller analyzes the patterns of air pressure and alerts the diver or an authority when a significant change is detected. The response element can be an inflatable vest, balloon, or belt with weights. The invention also includes a method for rescuing a diver by measuring air pressure patterns, alerting the diver or an authority, and changing the buoyancy of the diver. The device can be used in training and testing and is designed to bring the diver to the water surface quickly and safely."

Problems solved by technology

Diving is an inherently dangerous activity.
As divers can be tens of meters under the water surface and are often out of communication with others for extended periods of time, risks of air tank failure are potentially fatal.

first embodiment

[0050]Referring now to FIG. 2, a diving hose 214 allows for unidirectional flow 230 of oxygen or air from a tank (not shown) to a diver's mouth piece or to an inflator (not shown). A gas pressure sensor 240 measures the pressure associated with said flow 230 at all times during diving. The gas pressure sensor 240 is generally in contact with the flow 230 of gas either directly or indirectly. As shown, the gas pressure sensor 240 sits partially in the diving hose 214. Alternatively, some piping (not shown) can allow for gas to reach the gas pressure sensor 240 without the latter being in the direct flow 230 of gas to a diver. The gas pressure sensor 240 is in electrical connection 250 with a controller unit 260. The controller unit monitors gas pressure changes during a dive. The controller unit 260 is preprogrammed with gas pressure behavior either in general or for a particular diver. The controller unit 260 continually monitors data from the gas pressure sensor 240 and compares sa...

second embodiment

[0051]Attention is turned to FIG. 3, wherein is shown diving gas tank 302 with a diver rescue element 380 that includes both a gas pressure monitor as well as a controller element (not shown separately in this example). The diver rescue element 380 is contacted to the high-pressure regulator 303 attached to the tank 302. Though the regulator measures the high pressure gas leaving the tank, the diver rescue element 380 may be placed in contact with high pressure gas flow and still function properly.

third embodiment

[0052]Attention is turned to FIG. 4, which shows an alternative embodiment of the present invention. A diver rescue element 480 is placed along a hose 414 that has medium pressure gas coming from a tank 402 and is delivered to a diver's inflator 416. The diver rescue element 480 is connected 490 to the inflator hose 405 as shown. Should diver (not shown) stop breathing, as determined by anomalous breathing behavior, and should diver not respond to vibrations, sound or other local stimuli, the diver rescue element 480 can transfer air from the hose 414 to the inflator tube 404 in order to initiate ascent of the distressed diver.

[0053]A critical feature to note in the present invention is that all steps are performed automatically. The diver rescue element 480 monitors gas pressure from the tank to the driver without any required interference of the diver. Should there be a problem such as no breathing or inconsistent gas pressure, the diver rescue element 480 will first alert the div...

Abstract

The invention discloses devices and methods for identifying a diver in distress and initiating a rescue response. Specifically, embodiments of the present invention allow for identification of a diver who is not breathing properly and in response giving local stimuli to allow the diver to response. Should he / she not respond, the instant invention will initiate steps to bring the diver back to the water surface and alert others as to his / her need of assistance.

Description

FIELD AND BACKGROUND OF THE INVENTION[0001]The present invention, in some embodiments thereof, relates to methods for automatically aiding a distressed diver and, more particularly, but not exclusively, to methods for rapidly bringing a diver to the surface. The present application is a divisional application of U.S. patent application Ser. No. 12 / 791,021 of similar inventorship. Examiner of said application applied a restriction, which was accepted with traverse, and the enclosed application includes claims that have not been subject to examination.[0002]Diving is an inherently dangerous activity. Divers typically go down meters into ocean or fresh water and rely solely on air tanks and breathing devices for continued oxygen consumption and carbon dioxide removal. Diving is a popular recreation sport and is a required activity in diverse fields such as warfare, shipping, and tourism.[0003]A diver typically has an air tank with associated regulators and tubing for delivery of compre...
