Abstract: An apparatus and method for determining a physical parameter affecting an optical sensor or a number of sensors in a network. The apparatus uses a narrow linewidth source at an emission wavelength ?e and an arrangement for varying the emission wavelength ?e of the radiation. An analysis module with curve fitting is used to generate a fit to the response signal obtained from the optical sensor. The physical parameter is determined form the fit rather than from the response signal. The apparatus can be employed with Bragg gratings, etalons, Fabry Perot elements or other optical sensors.

Abstract: In an embodiment, the controller for machining parts on a work piece positioned on a numerically controllable (NC) machine includes a memory, a display and a plurality of layout processes. A job comprising multiple parts in various quantities is displayed textually as a job list of parts and quantities. The job is also displayed graphically in a scaled layout. In the scaled layout part icons corresponding to each of the parts on the job list are superimposed on a work piece icon in an arrangement corresponding to a physical part layout. Layout processes handle the location of the machine instruction records which correspond to the parts selected for the job. These processes also determine the dimension and scaling of each part icon on the basis of the machine code records for the chosen parts. The processes also handle the scaling of the work piece icon and parts icon on the display in an arrangement corresponding to an actual physical layout for the job.
