| 20100059911 | ADJUSTABLE GAS DAMPING VIBRATION AND SHOCK ISOLATION SYSTEM - An inertial measurement unit includes a housing with openings to permit fluid communication between at least one pressure source and two distinct cavities within the housing. The cavities are separated by an inertial sensor assembly coupled to a vibration isolator assembly. The pressure in the cavities may be adjusted or tuned to change a natural frequency of the inertial measurement unit, thus allowing the unit to be configured and even optimized for a variety of different applications. By adjusting the pressure in the respective cavities, gas squeeze film damping effects may be optimized when the inertial measurement unit undergoes a shock event and/or when the inertial measurement unit experiences vibration loads during operation. In one embodiment, the vibration isolator assembly includes perforations to permit fluid communication between the first and second cavities during specific operational events. | 03-11-2010 |
