A gyroscopic roll stabilizer comprises a gimbal having a support frame and enclosure configured to maintain a below-ambient pressure, a flywheel assembly including a flywheel and flywheel shaft, one or more bearings for rotatably mounting the flywheel inside the enclosure, a motor for rotating the flywheel, and bearing cooling system for cooling the bearings supporting the flywheel. For smaller units, the bearing cooling system is effective to enable a flywheel with a moment of inertia less than 40,000 lb in.sup.2 to be accelerated at a rate of 5 rpm/s or greater. For larger units, the bearing cooling system is effective to enable a flywheel with a moment of inertia greater than 40,000 lb in.sup.2 to be accelerated at a rate of 2.5 rpm/s or greater.

A hydraulic damper comprising a main cylinder, a piston slidably moveable within the main cylinder in compression and extension, the piston dividing the main cylinder into a main fluid chamber and an annulus fluid chamber, a piston rod extending from the piston through the annulus fluid chamber, and wherein the piston comprises a frequency sensitive damping (FSD) valve assembly configured to create a piston by-pass above a specified damper frequency, and further configured to lock the length of the hydraulic damper.

The invention relates to an oscillation damper which is in particular suitable for wind turbines and which is based on the eddy current principle and is temperature-controlled in such a way that it can not only effectively dissipate the heat generated by the eddy current but can also effectively and self-adjustingly compensate for the damping loss occurring at higher temperatures.

A system configured to provide thermal regulation and vibration isolation to one or more electronic components. The system includes a sensor chassis defining an interior chamber, an electronics housing in the interior chamber of the sensor chassis, a thermoelectric cooler coupled between the sensor chassis and the electronics housing, a thermal strap coupled to the sensor chassis, and at least one isolator coupled to the sensor chassis. The system may also include an insulating material, such as Aerogel, in the interior chamber of the sensor chassis and extending around the electronics housing.

Thermally conductive shock absorbers for electronic devices are disclosed. An electronic device includes a housing and a hardware component positioned inside the housing. A thermally conductive shock absorber is located between an inner surface of the housing and the hardware component. The thermally conductive shock absorber including an impact absorbing material and a thermal conductive material being in contact with at least a portion of the impact absorbing material.

Provided is an active engine mount having a vent hole that includes a damper assembly including an exciter. The damper assembly in the active engine mount which controls pressure of a main chamber as the exciter is excited has a vent hole that enables communication from a lower part of the exciter to the outside formed thereon such that air inside the damper assembly can be discharged to the outside.

A motor includes a motor housing, a motor body, and a damping member. The motor body includes a drive shaft. The motor body is housed in the motor housing. The damping member is disposed on an outer surface of the motor housing. The damping member includes a damping layer and a constraining layer. The damping layer is made of an organic polymeric material, and bonded to the outer surface of the motor housing. The constraining layer is made of at least one of a resin mixed with an inorganic compound and an elastomer mixed with an inorganic compound. The constraining layer is disposed on the damping layer.

A seismic base isolation support apparatus 1 includes: a laminated body 4 in which elastic layers 2 and rigid layers 3 are alternately laminated; a circularly columnar body 7 which is disposed in a hollow portion 6 of the laminated body 4; an outer peripheral protective layer 9 covering an outer peripheral surface 8 of the laminated body 4; an upper mounting plate 11 and a lower mounting plate 12 which are respectively connected to an uppermost rigid layer 3 of the rigid layers 3 and a lowermost rigid layer 3 of the rigid layers 3 by means of bolts 10; a shear key 15 which is fittingly secured in a recess 13 of the uppermost rigid layer 3 and a recess 14 of the upper mounting plate 11; and a shear key 18 which is fittingly secured in a recess 16 of the lowermost rigid layer 3 and a recess 17 of the lower mounting plate 12.

Disclosed herein is a fluid redirection system comprising a damper piston with a plurality of compression ports and a plurality of rebound ports. The damper piston also has a fluid ramp on a first side where the fluid ramp is of a shape that creates an angled exit for fluid exiting the damper piston.
