Abstract: An inflatable life vest has first and second sheets that are welded together to form an inflatable compartment. The inflatable life vest further includes an elongate inflation chamber that extends upwardly from the inflatable compartment and towards a neck aperture. An inflation tube is connected to the elongate inflation chamber for inflating the inflatable life vest through the elongate inflation chamber. The vest may further include an indicator for indicating when the vest is fully inflated.

Abstract: An incorrect-circuit deactivation device of a magnetic GFCI outlet includes an electromagnetic coil seat, a magneto-conductive core driven by the electromagnetic coil seat to displace, and two magnetic elements located on both sides of the magneto-conductive core. The magneto-conductive core is connected to a first electrical conductive end. The first electrical conductive end is positioned to face a second electrical conductive end. Electric power is supplied when the first electrical conductive end is brought into contact with the second electrical conductive end. The electromagnetic coil seat senses a reverse current to make the magneto-conductive core to displace toward one of the magnetic elements when there is a ground fault, thereby departing the first electrical conductive end from the second electrical conductive end to cut off the electric current.
