Abstract: A head-mountable device can securely support sensors in a manner that maintains their positions and orientations over time and avoids applying excessive strain on the sensors, thereby protecting them from harm. The sensor can be mounted on a flex circuit or circuit board, which is rigidly secured within an inner case, including for example a base and an inner shield. The inner case can be suspended within an outer case, including for example a frame and an outer shield. Shock absorbers on opposing sides of the inner case can flexibly couple the inner case to the outer case. The shock absorbers can dampen the effects of vibrations or other forces applied from the outer case. The inner case can decouple the sensor from strain applied from the shock absorbers.

Abstract: Three-dimensional (3D) micro-scale shells are presented with openings of various sizes and geometries on the surface. The shell consist of a suspended ring-shaped resonator, multiple support beams, a support post, and a cap region that connects the support beams to the support post. Shells with openings of various sizes and geometries allow the creation of micro electromechanical systems (MEMS) sensors and actuators with a wide range of engineered mechanical and electrical properties. The openings on the shell surface can, for example, control the mechanical quality factor (Q) and resonance frequencies of the shell when the shell is used as a suspended proof mass of a mechanical resonator of a vibratory gyroscope. The shells can also serve as mechanical supporting layers and/or an electrode connection layer for MEMS actuators and sensors that use 3D shells as proof masses.
