An apparatus and method for multiplexing voice packets to an ATM cell in an ATM network. The PbO3 based material can exhibit enhanced electromechanical coupling factors when compared to PZT based ceramics and can be used as high performance actuators, piezoelectric sensors andor ultrasonic transducers. The sealing member is rapidly absorbed after exposure within the vessel, e. The sensor and split flow correction factors may be used independently of each other in some embodiments. N2 atoms are implanted into the exposed surface of the thin layer of oxide, rapid thermal processing is performed and the blocking mask is removed from the surface of the thick layer of gate oxide.
