1. A system for detecting and responding to a situation of potential drowning, comprising:
a volume of water contained within an enclosure, which defines an interior and an exterior, wherein the volume of water fills the interior of the enclosure up to a waterline; one or more motion sensors positioned to detect movement above the waterline and able to distinguish intervals of movement above the waterline from intervals of movement cessation above the waterline; one or more drain outlets, which fluidly communicate between the interior and the exterior of the enclosure, wherein each drain outlet has a releasable drain plug, and wherein each drain plug has an unreleased closed position, in which the volume of water is retained within the interior of the enclosure, and wherein each drain plug has a released open position, in which the volume of water freely flows from the interior of the enclosure through a drain opening to the exterior of the enclosure; and wherein the motion sensors electrically communicate with the drain outlets, such that a detection by the motion sensors of a potential drowning pattern, comprising one or more intervals of movement above the waterline followed by one or more intervals of movement cessation above the waterline, causes the motion sensors to send one or more electrical signals to the drain outlets to effect a release of the drain plugs to the open position, thereby preventing the potential drowning by emptying the volume of water from the interior of the enclosure. |
