Abstract: One or more shock absorbers may be disposed between the layers of an optical assembly, which may be used in a head-mounted display (HMD) device for the display of augmented and/or virtual reality (AR/VR) content. In one example, an optical component positioned adjacent to a waveguide in the optical assembly may have one or more shock absorbers positioned on the surface which faces the waveguide. The shock absorbers may either touch the surface of the waveguide or may not touch the waveguide but rather have a gap (i.e., a stand-off shock absorber). The shock absorbers may take the form of, e.g., a pillar, a cone, an inverted cone, an inverted pillar, a spring, a double helix, a three-dimensional mesh, a strap, or a high aspect ratio 3D mesh tower.

Abstract: Techniques and apparatuses are described that perform respiration rate sensing. Provided according to one or more preferred embodiments is a hearable, such as an earbud, that is capable of performing a novel physiological monitoring process termed herein audioplethysmography, an active acoustic method capable of sensing subtle physiologically-related changes observable at a user's outer and middle ear. Instead of relying on other auxiliary sensors, such as optical or electrical sensors, audioplethysmography involves transmitting and receiving acoustic signals to monitor a user's respiration rate. In addition to being relatively unobtrusive, some hearables can be configured to support audioplethysmography without the need for additional hardware. As such, the size, cost, and power usage of the hearable can help make health monitoring accessible to a larger group of people and improve the user experience with hearables.
