Abstract: The traveling wave excitation system phase shifter chassis method and device of the invention is compact, inexpensive, and versatile when compared to customary methods for generating traveling wave excitation signals that would require using an equivalent number of commercial function generators. The method and device of the invention produces up to 56 simultaneous sine waves that are phase shifted with respect to one another.

Abstract: A stone cutting and finishing management system for managing an inventory of stone slabs is disclosed herein. The system includes a data management system with a database, an image station for creating a visual image of a slab from an inventory, each slab provided with a slab identifier, wherein the image and the identifier are stored in the database, a slab selection station with a visual display, a customer parts data file in the database including parts outline data, parts cutting data, and parts finishing data, a parts nesting system for displaying the parts outline data electronically on a selected slab image, a parts tagging station for projecting part outlines on the slab, wherein a part tag is attached to each part outline on the slab, a parts cutting station for cutting the parts from the slab in accordance with the data in the database, and a parts finishing station for providing a finishing process to the cut parts in accordance with the data in the database.
