Abstract: A fluid flow regulator adapted to be inserted into a conduit and inflated to form a leak tight sealing contact with the interior wall of the conduit. The fluid flow regulator includes a toroidal inflatable member mounted on a cylindrical annular mount which attaches to a flow-through pipe. The fluid flow regulator also includes a fluid flow control valve within the inner portion of the toroidal inflatable member which can be opened and closed to control the flow of fluid from the reservoir through the conduit.

Abstract: An automated water safety apparatus is disclosed including, a spray device, a sensor, a container, a processor capable of sending and receiving signals, and a liquid substance that becomes a buoyant solid when released from the spray device, wherein the water safety device is coupled to a water vessel. Additionally, a method is disclosed for creating buoyant solids in water in response to a water vessel beginning to sink, including determining whether the water vessel is sinking, sending a signal to the processor to indicate that the vessel is sinking, the processor instructing the container to release the liquid substance, and propelling the liquid substance into the water to form buoyant solids.
