  • HIGH QUALITY FACTOR MEMS SILICON HINGE AND SLOT-CUT RESONATOR FOR A VIBRATORY GYROSCOPE
    Publication number: 20190072388
    Abstract: A resonant structure comprising at least two coaxial rings, wherein adjacent coaxial rings have adjacent peripheries and are attached together by a plurality of connection structures regularly arranged along said adjacent peripheries; and wherein a first ring has a first ring portion with a first radial thickness and a second ring, portion, in a vicinity of a first connection structure, with a second radial thickness smaller than said first radial thickness.

  • MICROLATTICE DAMPING MATERIAL AND METHOD FOR REPEATABLE ENERGY ABSORPTION
    Publication number: 20170307040
    Abstract: Described is a micro-lattice damping material and a method for repeatable energy absorption. The micro-lattice damping material is a cellular material formed of a three-dimensional interconnected network of hollow tubes. This material is operable to provide high damping, specifically acoustic, vibration or shock damping, by utilizing the energy absorption mechanism of hollow tube buckling, which is rendered repeatable by the micro-lattice architecture.

  • PROGRESSIVE STIFFNESS STRUCTURAL-ACOUSTIC SANDWICH PANEL
    Publication number: 20160046095
    Abstract: A sandwich material having both structural strength and significant acoustic attenuation. In one embodiment, a sandwich is composed of an architected core secured between two facesheets, with a compliant layer forming the connection between the core and the facesheets. The compliant core has a low modulus, resulting in a low speed for elastic shear waves in the sandwich, at low static loads. At high static loads the compliant material stiffens and allows the sandwich to exhibit significant structural strength.
