An orientation sensor capable of generating at least one output signal indicative of a particular orientation parameter is described. The sheet is held in a stretched state until the fibers set in place. The method comprises the following steps: a) removing from the polymerization reactor at \u221260 to 020 C. The host material is an electron-transport compound. Operation of the asynchronous logic is synchronized at least in part with a clock signal associated with the synchronous test equipment. The present invention also discloses a method and apparatus for performing on-chip impedance matching for a transmission line.
