Abstract: Additive manufacturing systems, area scanning laser systems, and methods for performing an additive manufacturing process are provided. An exemplary additive manufacturing system includes a laser generation device for producing a laser beam. Further, the additive manufacturing system includes an optic element for forming a first portion of the laser beam with a first polarization and a second portion of the laser beam with a second polarization different from the first polarization to encode an image in the laser beam. Also, the additive manufacturing system includes a selective beam separator configured to direct the first portion of the laser beam onto a material to be sintered or melted. The additive manufacturing system includes a recycling system for receiving the second portion of the laser beam.

Abstract: A linear magnetic sensor shield system comprises first and second shield parts. The system may include first and second field sensor assemblies, each having field sensors disposed therein. The first shield part may be disposed adjacent to a first side of the first field sensor assembly, and the second shield part may be disposed adjacent to a second side of the second field sensor assembly. The shield parts may be formed of mu metal or a mu metal and steel composite, by of example. A torque transmitting device is also provided.
