The gyroscope-generator association works as the damper element of a mass-spring-damper system.

The mass is located along the spring with the first and second portions of the spring extending on opposite sides of the mass.

The mass layer (440) provides a substantially independent spring mass contribution to the spring model without affecting the equivalent spring constant.

The transducer has a base (401), a spring layer (420) placed over the base (401), and a mass layer (440) connected to the spring layer (420) through a spring-mass connector (450).

The spring housing is affixed to the first endmass, a first end of the spring being affixed to the spring housing, and tether are affixed to spring at one end and to the second endmass at the other end.

A lock includes a stationary key mass having a first key mass bore and a keyway, and a movable spring mass including a first spring mass bore.

The acoustic insulation comprises a heavy mass and an acoustic spring layer.

The two spring-mass systems vibrate in antiphase.

A spring assembly couples the armature to the output mass, the spring assembly including two spring portions with a node point therebetween, wherein when the armature rotates, the brushhead moves in an opposite direction.

This is the basis of the "Mass-Spring-Mass" principle.

The invention relates to a spring device capable of softly dissipating the energy of an accelerated mass which is relatively great with respect to the inert mass of a reference system coupled to said spring device.

The variable stiffness mechanism has an effective spring constant between the sprung mass and the unsprung mass, and wherein the effective spring constant depends on a frequency of excitation of the unsprung mass.

The mass interacts with the fluid flow and oscillates with the spring.

A mass (18) receives the vibrations through a spring (16).
