A multi-performance hysteretic rheological device. The invention concerns a mechanical device capable of providing restoring forces with non-linear hysteresis loops whose shapes can be adjusted depending on the specifications required by the application. The forces exerted on rigid sliding blocks on smooth bars are for example produced by the wire ropes composed of steel and shape-memory material wires. The device according to the invention can be used in very different applications including: vibration damper, hysteretic insulator, energy absorber, shock absorber, applications in which a specific rheological body with force-displacement characteristics of hysteretic type is required.

The apparatus for non-contact damping vibration of a vibrating optical fiber moving over an optical fiber path includes an air bearing and an air supply. The air bearing includes a body having an aperture defined by an inner surface and a central axis that passes through the center of the aperture and along which lies the optical fiber path. A plurality of nozzles is distributed around the inner surface and directed toward the central axis. An air conduit within the body is in pneumatic communication with the plurality of nozzles. The air supply is pneumatically connected to the air conduit and is configured to supply pressurized air to the air bearing. The pressurized air is directed through the nozzles to the vibrating optical fiber and impinges on the optical fiber to damp the vibration of the vibrating optical fiber.

According to certain embodiments, a vibration-isolating system comprises a platform adapted to carry one or more loads and an adjustable load-positioning system. The platform is suspended within a support structure by a plurality of isolators. The isolators are tuned to impede vibrations in a pre-determined frequency range for a payload having a pre-determined mass. The adjustable load-positioning system is adapted to facilitate positioning the one or more loads such that the payload having the pre-determined mass is centered at the center of gravity of the platform.
