    Abstract: An automatic popup device assembly that electromechanically opens and closes a sink drain stopper plug. The device operates from within a waterproof capsulated cartridge that seamlessly attaches to a standard water drain pipe assembly. The device is powered by either a linear type solenoid or a low voltage linear dc gear motor to provide the force to raise and lower the stopper plug. The triggering mechanizing to actuate the stopper plug is a motion sensor. More commonly know as (IR), or (PIR) Infrared, Passive infrared motion control activating method. A secondary triggering mechanizing is the touch controller method whereby touching the stopper plug or external object such as the faucet or wall switch to raise or lower the stopper plug assembly automatically preventing the escape of water. A third triggering method to raise or lower the stopper plug is by a hand held remote controller through a (RF) radio signal frequency instructing to the popup device to engage.
