A vibration isolator can be configured to provide improved vibration isolation performance, such as in connection with a bicycle saddle. A vibration isolator can be operatively connected to a bicycle saddle. The vibration isolator can be configured to exhibit a non-linear stiffness profile. The non-linear stiffness profile can include a region of quasi-zero stiffness. The vibration isolator can include one or more movable body members and one or more super elastic material members.

The copper plating layer 20 has a crystallite size of 220±50 Å.

A magazine for storing and feeding ammunition cartridges to a small arms weapon which comprises a casing, a floor plate, a follower, and a magazine spring inside the casing. The magazine spring may comprise a first end connected to the follower, a second end connected to the floor plate, and a plurality of coils. Each of the plurality of coils may include a first segment having a first radius, a second segment having a first length adjoining the first segment, a third segment having a second radius adjoining the second segment, the second radius being greater than the first radius, and a fourth segment having a second length adjoining the third segment, the second length being approximately equal to the first length.

The invention relates to a vacuum chamber packaging machine with spring fracture detection. A first electrical line can be provided connecting springs to a controller, where interruption of the line due to a fractured spring may be detected by the controller via an applied voltage, so that no safety deficiency arises.

This invention teaches a new class of materials that can be used to manufacture hairsprings and/or other components of mechanical watches, and methods for manufacturing these components. The new class of materials is crystalline compounds, including, but not limited to, gallium arsenide, extrinsically doped gallium arsenide, extrinsically doped silicon, gallium nitride, extrinsically doped gallium nitride, gallium phosphide, extrinsically doped gallium phosphide, and quartz. This invention also teaches laminated/coated crystalline compounds. The lamination/coating may be applied by one of the following methods, including but not limited to: plasma enhanced chemical vapor deposition, atomic layer deposition, sputtering, electron beam evaporation, and thermal evaporation. Using crystalline compounds, in particular extrinsically doping the crystalline compounds, affords the possibility to controllably alter the mechanical, electrical, thermal, magnetic, and/or other properties of the watch components. These properties can be further altered by applying single or multiple laminates/coatings of varying thicknesses and/or geometries.
