  • Compact vibration isolation system for an inertial sensor assembly
    Patent number: 6578682
    Abstract: Disclosed is a compact vibration isolation system for mounting an inertial sensor assembly (ISA) to an Inertial Measurement Unit (IMU) housing. The housing is mounted to a support that is subjected to shock and vibration. The vibration isolator assembly includes a ring shaped elastomeric member laminated between a ring shaped inner member and a ring shaped outer member. The inner member is securely mounted to the ISA, and the outer member is mounted to a support of the IMU housing. Because of the compact size of this system, the IMU housing contains and protects the elastomeric member from potential contamination and damage, as well as eliminates the need for delicate mechanical and electrical interfaces. The elastomeric member of the system isolates the ISA from shock, vibration, and acoustic energy that may otherwise be transmitted from the support to the ISA.
