In some embodiments, a noise reduction circuit comprises an insulated wire comprising a conductor and insulation. A shielding material is oriented around the insulated wire. The shielding material comprises metallized fibers.

Noise reduction circuit

In some embodiments, a vibration isolator comprises a housing having a base portion and a wall portion. A plurality of bearings are disposed within the housing. The bearings are arranged in a configuration comprising a plurality of layers. A first layer comprises a bearing and a second layer comprises a plurality of bearings. Each bearing in the second layer contacts the wall portion of the housing. Each bearing comprises a plurality of contact points in contact with another portion of the vibration isolator, and no two contact points of a bearing are diametrically opposed.

Vibration isolator

An acoustic panel device includes a panel member and a mount. The panel member includes a porous material. The mount is arranged to captively support the panel member. The mount can be a frame that surrounds the panel member. The frame can define a channel, and a portion of the panel member is disposed in the channel.

Acoustic panel

A device for the control of vibrations comprises a retainer resting on a base and a plurality of bearings disposed within the retainer. The bearings are arranged in a first layer and a second layer. The second layer is disposed on the first layer. The first layer comprises three or more bearings and the second layer comprising one or more bearings. Each bearing in the first layer is constrained on its bottom only by a substantially flat portion of the base, on its side by the retainer and is in contact with at least two adjacent bearings in the first layer. The bearings in the first layer support the bearing in the second layer. The retainer has a surface which is in substantially tangential contact with the bearings in the first layer.
