  • Guided projectile with motion restricting piezoelectric actuator
    Patent number: 8573056
    Abstract: An inertial measurement unit may include a housing having an internal volume. The internal volume may have a dimension along an axis. A sensing element may be disposed in the internal volume. The sensing element may have a dimension along the axis that is less than the dimension of the internal volume. At least one piezoelectric actuator may be disposed in the housing adjacent the sensing element. When the at least one piezoelectric actuator is activated, it may prevent movement of the sensing element along the axis. When it is not activated, it may not prevent movement of the sensing element along the axis.
