Abstract: A laser crafting apparatus for directing electromagnetic radiation toward a workpiece may include various features. For example, the laser crafting apparatus may include a material support tray that is removably supported within an internal volume of the laser crafting apparatus. Further, the apparatus may include pre-filter disposed in a ventilation pathway between a workspace region of the internal volume and an extractor fan. The laser crafting apparatus may include a laser carriage assembly that houses a laser module and the assembly may include a lens tray detachably coupled to the support structure of the laser carriage assembly. In various embodiments, the laser crafting apparatus includes a lid having a radiation attenuation layer and a fire suppression layer.

Abstract: An airfoil and a method of manufacturing an airfoil may be provided, where the airfoil comprises a core and a shell. The core comprises core ceramic fibers extending along a span of the airfoil. The shell surrounds the core and includes shell ceramic fibers. Substantially all of the core ceramic fibers are arranged in a radial direction. The airfoil may also be a ceramic matrix composite formed by infiltrating the core and the shell with a matrix material.

Abstract: A method for assembling data by sorting and filtering new data records and old data records, such as data records that an Electronic Program Guide data provider typically transmits to a head end of a cable television system. New incoming data records are combined with existing stored data records to form combined data records. Each of the data records is assigned an array index value. The combined data records are then sorted into one field of multiple fields. Within each field, each sorted data record is compared with other sorted data records and any conflicting data record is removed. The remaining non-conflicting data records are compared within each field and exact duplicate data records are removed from each corresponding field. The remaining processed data records are compared within each field and any older difference duplicate data record is removed. The filtered data records are then transmitted to a database.
