Abstract: A display assembly monitors movements in a waveguide assembly and corrects for aberrations in image light caused by the monitored movements. For example, an artificial reality headset may include a display assembly that monitors for changes in shape or displacement of waveguide assemblies that generate three dimensional images for display with a real world environment. The display assembly includes movement sensors (e.g., piezoelectric movement sensors) coupled to the waveguide assembly. The movement sensors monitor the movement of the waveguide assembly and provide the monitored movement to a display controller that generates instructions for correcting aberrations in the image light.

Abstract: A headset comprise a frame and a vibration sensor coupled to the frame. The vibration sensor may be located in a nosepad of the frame, and configured to measure tissue vibrations of a user when the headset of worn by the user. A controller receives a signal corresponding to the measured vibration data from the vibration sensor, and analyzes the received signal to infer a sequence of states of the received signal, such as a sequence of respiratory states. The controller further determines a value of a health metric based upon the inferred sequence of states, e.g., a respiratory rate of the user, and performs an action using the determined value of the health metric.

Abstract: A displacement sensor measures capacitance between a rotor-stator pair. The displacement sensor includes a plurality of stators coupled to a first object. The plurality of stators is oriented parallel to an axis of motion between the first object and a second object. The displacement sensor further includes a plurality of rotors coupled to the second object. The plurality of rotors is oriented parallel to the axis of motion. Each rotor of the plurality of rotors is aligned with and configured to receive a corresponding stator of the plurality of stators to create a respective rotor-stator pair. Capacitance between the rotor-stator pairs change as a function of position of the first object relative to the second object along the axis of motion. An amount of displacement of the first object relative to the second object is determined based in part on the capacitance values.

Abstract: In certain embodiments, an accelerometer is a microelectromechanical systems (MEMS) device including a proof mass, an anchor located in an opening defined by a body of the proof mass, a spring, a drive electrode, and a sense beam. The spring and the proof mass form a spring system suspended from the anchor. The sense beam oscillates at a particular resonance frequency based on application of a signal to the drive electrode. The MEMS device further includes a support structure coupled to the anchor. The support structure operates as a stress decoupling area and includes a support beam, with the spring corresponding to an end of the support beam that has a reduced thickness. The sense beam has a first end attached to the proof mass and a second end attached to the support beam such that the sense beam is orthogonal to the support beam.
