A method for making a transistor 20 that includes using a transition metal nitride layer 200 andor a SOG layer 220 to protect the sourcedrain regions 60 from silicidation during the silicidation of the gate electrode 90. The electrical power for the array is provided by way of a rotating contactless transformer independently of the control data for the array which is provided by infrared data transmission through a tubular shaft driven by a DC brushless, three-phase motor to rotate the array at a predetermined rate independent of the electrical power for the array and the control data. ambiguities, derived from GNSS signals. The invention constructs the model so that the model has a maximum volume that is consistent with the set of labeled regions in the input images. Embodiments are provided in which the amplifiers, typically transimpedance amplifiers, are closely integrated with the optical detectors that detect the interference signals from the interferometer.
