An asymmetry thin-film transistor includes a substrate, a semiconductor layer and a gate positioned on the substrate. Each portal is positioned above a respective aperture and adapted to position an infant feeding over the respective aperture. An outlet receptacle is mounted to the cord for supplying power to remote locations in the room or work area as the cord is unwound from the reel. The height of the via to be filled is thus reduced by the height of the intermediate plug. Thus, a raw image signal with an emphasized edge is obtained.
