  • Patent number: 11185608
    Abstract: A method of improving the fatigue life of a superelastic medical device includes applying a compressive stress to a fatigue critical location of a medical device comprising a superelastic nickel-titanium alloy, where the compressive stress induces a compressive strain of greater than 9% in the fatigue critical location. After inducing the compressive strain, the compressive stress is released. A tensile stress is applied to the fatigue critical location of the medical device, where the tensile stress induces a tensile strain of greater than 9% in the fatigue critical location. After inducing the tensile strain, the tensile stress is released. After application and release of each of the compressive stress and the tensile stress, the fatigue critical location includes a non-zero amount of residual strain, and the medical device may exhibit improved fatigue properties.

  • Patent number: 11167346
    Abstract: A method for making a pyrotechnic composition in accordance with an embodiment of the present technology includes flowing metal powder, polytetrafluoroethylene powder, and binder powder in separate respective feed streams toward an extruder. The binder powder includes adhesive material and polytetrafluoroethylene anticaking material coating the adhesive material. The method further includes interspersing the metal powder, the binder powder, and the fluoropolymer powder to form a mixture.

  • Patent number: 11125966
    Abstract: A lens alignment system and method is disclosed. The disclosed system/method integrates one or more lens retaining members/tubes (LRM/LRT) and focal length spacers (FLS) each comprising a metallic material product (MMP) specifically manufactured to have a thermal expansion coefficient (TEC) in a predetermined range via selection of the individual MMP materials and an associated MMP manufacturing process providing for controlled TEC. This controlled LRM/LRT TEC enables a plurality of optical lenses (POL) fixed along a common optical axis (COA) by the LRM/LRT to maintain precise interspatial alignment characteristics that ensure consistent and/or controlled series focal length (SFL) within the POL to generate a thermally neutral optical system (TNOS). Integration of the POL using this LRM/LRT/FLS lens alignment system reduces the overall TNOS implementation cost, reduces the overall TNOS mass, reduces TNOS parts component count, and increases the reliability of the overall optical system.
