Abstract: Three-dimensional (3D) micro-scale shells are presented with selectively removed regions/openings and which can be used in sensors and actuators, including gyroscopes. Example shells consisting of a suspended ring-shaped resonator that is supported using multiple beams that are not in the plane of the ring and are attached to a support post can be formed. Shells with various sizes and geometries of selectively removed regions and openings allow the creation of micro electromechanical systems (MEMS) sensors and actuators with a wide range of engineered mechanical and electrical properties. These shells can be used to form stacked 3D structures for various types of MEMS sensor and actuator devices, such as resonant gyroscopes, with sense and drive electrodes that conform to the curved profile of the resonant shell using for gyroscopes. 3D shells formed from a starting parent substrate are released and separated from their parent substrate using a number of techniques.

Abstract: Described herein are examples of tool based welding technique monitoring systems that provide an inexpensive, intuitive, and relatively robust way of tracking an orientation of a welding-type tool, and providing welding technique feedback based on the orientation. The system requires no sensors apart from a simple and/or relatively inexpensive sensor module that can travel with the welding-type tool, which makes the system highly portable. The system can also provide some feedback with minimal calibration, which can be valuable in situations where an operator forgets, or is unwilling, to take the time to fully calibrate the system. Additionally, full calibration of the system can be accomplished with a fast, simple, intuitive calibration technique.
