A lightweight passive attenuator (1) for spacecraft includes two omega cross-section rings (2), placed symmetrically and defining a gap therebetween, and being the main load path of the light passive attenuator (1). A plurality of damper elements (3) are placed in the gap defined between the two omega cross-section rings (2), and not in the main load path of the light passive attenuator (1), such that the omega cross-section rings (2) and the damper elements (3) are assembled at their ends by attachment elements. The omega cross-section rings (2) have a protruding central part (5) with a plurality of holes (6) for connection with adjacent structures (7, 8) of the spacecraft.

The present invention describes a novel spring mechanism for a razor. In the razor, the spring member may be disposed in a movable member assembly, portions of which may be used for ejection or pivoting. The spring may be fully encompassed within the assembly and be placed within supporting structures therein. The spring is a loop-shaped element having overlapping end portions with free distal ends. Alternately, the spring member is tear drop shaped loop shape with distal ends that are spaced apart. The spring may be disposed within a first and/or second movable member such as an eject button or a pivot member. A retarding structure on the spring provides a retarding force which is based on the interaction of the retarding structure with a protrusion on an assembly portion to keep the spring orientation intact. The spring is desirably comprised of stainless steel and is a flat wire.

A method of making a carbon fiber wave spring includes forming a disc-shaped ring from prepreg carbon fibers. The disc-shaped ring is then formed into a desired wave shape. The disc-shaped ring in the wave shape is then cured to form a wave spring.
