Patent Application
20120122358
The present invention generally relates a life vest. More specifically, the invention relates to a life vest with a hydration system and personal locator transmitter.
The use of emergency position indicating radio beacons for locating personnel stranded at sea or on land are well known in the prior art. Typically, the device is battery powered, compact, and when turned on, a device will transmit radio waves at predetermined frequencies, typically 121.5 MHz and 243 MHz, which are guard channels that are listened to for emergency situations. By sending out an emergency signal at these frequencies, the Coast Guard and other surrounding people who are alerted to the guard channels are aware of the emergency and can use the frequency transmissions for locating the downed personnel.
However, transmission of the beacon merely provides a signal that requires triangulation by emergency craft. The need to hone-in on a signal, without further information, may cause delay because of the lack of more exacting location information.
As can be seen, there is a need for a more exacting location system for water-born survivors, and a hydration system.
In one aspect of the present invention, a life vest, comprises a hydration pack capable of providing hydration to a user of the life vest; and a personal locator having a global positioning system receiver and transmitter capable of transmitting a global positioning system location of the user of the life vest.
In another aspect of the present invention, a life vest comprises a front panel having a top, a hydration pack capable of providing hydration to a user of the life vest, the hydration pack having a top and a bottom, wherein the top of the front panel is attached to the top of the hydration pack, and a strap attached to the bottom of the hydration pack capable of fitting around a waist of the user during use of the life vest.
These and other features, aspects and advantages of the present invention will become better understood with reference to the following drawings, description and claims.
The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Various inventive features are described below that can each be used independently of one another or in combination with other features.
Broadly, embodiments of the present invention generally provide a hydration system and life vest or life jacket within a single unit with a built-in waterproof personal locator.
With reference to
In one embodiment, the hydration pack 14 may be attachable to the rear portion of the life vest 12. A flow tube 18 may extend from the hydration pack 14 with enough length to allow for easy reach to the mouth of a user. A waterproof pocket 26 may be included to hold the personal locator 24, and protect electronics used by the personal locater 24 from water and the elements. In one embodiment two waterproof pockets 26 may be provided to allow for additional storage of food or other articles that the user wishes to keep dry.
In one embodiment, a mouthpiece 18 may be attached to the flow tube 18. The mouthpiece 18 may comprise a rigid tubular body glued to, or formed with, the flow tube 18, which may fit in the user's mouth and allows suction of liquid by the user from the hydration pack 14. An on/off valve 22 may allow the user to close off the mouthpiece from flow of liquid when the user is not drinking from the hydration pack. When in the closed or off position, the on/off valve 22 may prevent leakage from the hydration pack 14 during non-use of the life vest 12, and may prevent back-flow or salt water intrusion during use of the life vest 12 when the user is not drinking from the hydration pack 14.
With reference to
The personal locater 24 may comprise a combination global positioning system (GPS) locator and transmitter. The GPS portion of the personal locater 24 may determine GPS coordinates of the user from the well-known GPS system currently in use World-Wide. In one embodiment, the GPS coordinates are constantly transmitted in regular intervals by the transmitter portion of the personal locator to be received by rescue personnel. The rescue personnel may then input the received coordinates into rescue aircraft or watercraft GPS guidance systems to guide them to the user wearing the life vest 12. GPS tracking devices that transmit location information are widely available for use as the personal locater with the system 10, including the FAST FIND GPS personal locator, available from McMurdo Ltd. of Portsmouth, United Kingdom.
