Patent number: 11981176Abstract: An active damper is provided for a motor vehicle including a sprung mass, an unsprung mass coupled thereto and at least one wheel and tire combination coupled to the unsprung mass such that road terrain movement acting on the at least one wheel and tire combination along a z-axis induces movement of the unsprung mass along the z-axis which, in turn, induces movement of the sprung mass along the z-axis. The active damper may include a housing configured to be mounted to the unsprung mass, a damper mass received within the housing and movable relative to the housing, and an actuator configured to be responsive to a drive signal to cause the damper mass to move within the housing so as to cancel, or at least reduce, movement of the unsprung mass resulting from the road terrain movement.Type: GrantFiled: February 9, 2022Date of Patent: May 14, 2024Inventor: Gene Hawkins

Patent number: 9017590Abstract: Solid-state deformation processing of crosslinked high molecular weight polymers such as UHMWPE, for example by extrusion below the melt transition, produces materials with a combination of high tensile strength and high oxidative stability. The materials are especially suitable for use as bearing components in artificial hip and other implants. Treated bulk materials are anisotropic, with enhanced strength oriented along the axial direction. The material is oxidatively stable even after four weeks of accelerated aging in a pressure vessel containing five atmospheres of oxygen (ASTM F2003). Because of its oxidative stability, the deformation processed material is a suitable candidate for air-permeable packaging and gas sterilization, which has thus far been reserved for remelted crosslinked UHMWPE.Type: GrantFiled: March 5, 2013Date of Patent: April 28, 2015Assignee: Biomet Manufacturing, LLCInventors: David W. Schroeder, Jordan H. Freedman, James E. Gunter, Brian D. Salyer, H. Gene Hawkins

Patent number: 8262976Abstract: Solid-state deformation processing of crosslinked high molecular weight polymers such as UHMWPE, for example by extrusion below the melt transition, produces materials with a desirable combination of physical and chemical properties. Crosslinked bulk materials are heated to a compression deformable temperature, and pressure is applied to change a transverse dimension of the material. After cooling and stress relieving, a treated bulk material is obtained that has enhanced tensile strength in the axial direction orthogonal to the dimension change. In preferred embodiments, medical implant bearing materials are machined from the treated bulk material with the in vivo load bearing axis substantially parallel or coincident with the axial direction of the treated bulk material.Type: GrantFiled: May 22, 2009Date of Patent: September 11, 2012Assignee: Biomet Manufacturing Corp.Inventors: David Wayne Schroeder, Jordan H. Freedman, James E. Gunter, Brian D. Salyer, H. Gene Hawkins
