A bi-stable magnetic switch assembly comprises a stator having an axis and first and second magnetic portions angularly disposed there around, and a rotor having at least one magnetic region attracted to the first and second portions. The rotor is configured for rotation about the axis between (1) a first latched position wherein the region resides proximate to, but is spaced apart from, the first portion; and (2) a second latched position wherein the region resides proximate to, but is spaced apart from, the second portion. A spring biases the rotor to a position where the region resides intermediate the first and second portions. A coil, which is associated with at least one of the first portion, the second portion, and the region, may be energized to reduce the force of attraction between the region and the first and second portions when in the first and second latched positions, respectively.

Bi-stable magnetic latch assembly

A magnetic latch includes a stator having first and second permanent magnets disposed on either side of a center portion. Each of the first and second permanent magnets has at least two associated poles. A rotor has at least one magnetic region. The rotor is configured for rotation about an axis of the stator between a first latched position and a second latched position.

A mass damping system for use in all temperature ranges, including extreme temperature environments, is provided. The system comprises a housing having bottom, side and end walls, and an inner peripheral surface that defines an interior, a mounting mechanism located on the housing, configured to mount the housing to the mass, and macro-particles disposed within the housing interior able to flow within the housing and simulate a liquid.

Apparatus for damping vibration using macro particulates

A hermetic seal ( ) for a limited rotation device ( ) includes a plurality of vertical convolutes ( ) bonded to a device housing ( ) at their respective first ends ( ). At their respective second ends ( ), plurality of the vertical convolutes ( ) are bonded to a plurality of horizontal convolutes ( ). The plurality of horizontal convolutes ( ) are bonded to a device shaft ( ) at an end opposite of the plurality of vertical convolutes ( ). The plurality of vertical convolutes ( ) stretch in order to provide limited rotation and the horizontal convolutes ( ) expand or contract to accommodate length changes of the plurality of vertical convolutes ( ). The hermetic seal ( ) permits limited rotation while defining a barrier ( ) and preventing viscous fluid leakage to an external environment.

Hermetic seal for devices with limited rotation

A rotary damper ( ) includes a stationary member ( ) and a rotating member ( ) provided within the stationary member ( ) so that a gap ( ) is defined between the rotating member ( ) and the stationary member ( ). The rotating member ( ) further includes a central shaft ( ) provided therein. A viscous fluid ( ) is provided in the gap ( ) and has an associated shear that provides a velocity damping within the gap ( ). A differential growth in the gap ( ) caused by temperature variation compensates for temperature damping variation. A compliant member ( ) is provided within the stationary member ( ) for providing thermal compensation. A secondary hermetic seal ( ) is provided on the stationary member ( ) for permitting limited rotation, defining a vacuum environment and preventing viscous fluid leakage to an external environment.
