Abstract
A pressure-activated flotation device for use with an electronic device includes an attachment feature, chemicals, a container, a removable cap, an inflatable tube, and a pressure-activated valve. The inflatable tube is fluidly connected to the container and is configured to inflate with the expanding gas when the chemicals are exposed to a liquid. The pressure-activated valve leads from the outer surface of the container to the inner volume of the container and includes a one-way valve that opens to allow liquid to flow to the inner volume of the container when the pressure-activated flotation device is submerged in the liquid to a depth where the pressure applied against the pressure-activated valve by the liquid is greater than an actuation pressure. The one-way valve also closes when the expanding gas generates a gas pressure inside the inflatable tube that exceeds a threshold.
