A DS3 frame structure, video data transmittingreceiving apparatus and method for transmitting and receiving video data can minimize the transmission error during the video data transmission, and can multiplex and transmit two video signals using the DS3 formatted frame. The suction head comprises a planar flange portion and a tubular connector piece on a first face that communicates with an aperture extending to a second face. The invention also provides pharmaceutical compositions and methods for treating diseases, for example Alzheimer’s disease, in mammals comprising compounds of Formula I. A data relay is connected to the hard wired communication link of the irrigation controller. The translator software may be embodied as a computer readable medium storing a series of process steps allowing the user to create the procedures.
