Abstract: A Bidirectional telephone communication system for supporting a multiplicity of subscriber lines at a downstream distribution terminal using only two of a multiplicity of pre-existing transmission line pairs connected between an upstream distribution terminal and the downstream distribution terminal. Standard PCM data packets are mapped into and disguised as standard European HDSL formatted data.

Abstract: A writer pole and a method for fabricating a writer pole is disclosed. The method comprises fabricating a conductive seed layer on a gap substrate and then fabricating a nonmagnetic feature on the seed layer where the nonmagnetic feature has a top layer and a plurality of sides. The seed layer and nonmagnetic feature are covered with photoresist. A window is fabricated in the photoresist, exposing a portion of the nonmagnetic feature and a portion of the seed layer, thereby exposing a top portion and a side portion of the nonmagnetic feature and exposing a portion of the seed layer. The portion of the seed layer in the window area is removed from the gap substrate. A pole is fabricated on the top and side portions of the nonmagnetic feature in the window area.

Abstract: Methods and apparatus are provided for controlling dose uniformity in an ion implantation system. According to one embodiment of the invention, an initial scan waveform is adjusted to obtain a desired uniformity for use in a first implant process, and the adjusted scan waveform is stored. The stored scan waveform is recalled and used in a second implant process. According to a another embodiment of the invention, desired beam parameters are identified and, based on the desired beam parameters, a stored scan waveform is recalled for use in a uniformity adjustment process, and the uniformity adjustment process is performed. According to a further embodiment of the invention, an apparatus is provided that includes a beam profiler for measuring a current distribution of a scanned ion beam.
