The authors of the startup OneUp believe that the good old lifebuoy made of floating material can become obsolete overnight if everyone has their product at hand. This is a float that, upon contact with water, inflates faster than a drowning person has time to get confused. And it is much easier to carry with you than any other life-saving device.
Structurally, OneUp consists of an open-circle polyurethane float, a pressurized CO 2 cylinder, a cover and an activation mechanism. The latter contains a chemical component that reacts to moisture, instantly dissolving and opening the lock. Gas rushes into the container, the float is pushed out of the cover and fully inflated within 2 seconds.
With its modest dimensions (an extreme float in a case the size of a glass of coffee and weighs only 363 grams), when inflated, the device keeps up to 150 kg of weight afloat. It can be worn around your neck, passed over your shoulder, wrapped around your waist, or docked multiple floats together. Once the danger is over, the OneUp deflates, folds back into its case and is ready to be reused. The price of the device is $ 49 per copy.
Due to its compact size, OneUp can be very useful for professional rescuers - a trained person can easily and accurately throw a cover with a float over a long distance. And if you have a service station, it is not a problem to keep on hand "ammunition" from dozens of loaded floats.
