Patent number: 11821487Abstract: The present invention provides a vibration mitigation device which includes a vertically extending housing and a reciprocating assembly coupled with and fully enclosed inside of the vertically extending housing. In accordance with an exemplary embodiment of the present invention, the vibration mitigation device may utilize a tension spring as the biasing member while operating in a pneumatic process, an eddy current dampening process or a hybrid combination of the two dampening processes. For low amplitude, the eddy current dampening process may provide improved vibration mitigation results and for higher amplitudes, the pneumatic process may provide improved vibration mitigation results. Other exemplary embodiments include a vibration damping element that utilizes a compression spring as a biasing member for mitigating vibrations. Further exemplary embodiments provide a vibration damping element that utilizes a compression spring and a tension spring as biasing members for mitigating vibrations.Type: GrantFiled: October 22, 2021Date of Patent: November 21, 2023Inventors: Carl J. Macchietto, Richard E. Christenson, Darren E. Ingram

Patent number: 10900532Abstract: The present invention provides a method and apparatus for energy absorption and vibrational dampening in a horizontal plane. According to a first preferred embodiment, the present invention discloses an apparatus for damping vibration of a pole which includes a housing with a horizontal floor having an inward curved surface for achieving vibration attenuation at a middle portion thereof to form an enclosed chamber. According to a further aspect of the first embodiment, at least one damping weight is preferably disposed in the inward curved surface and is preferably substantially spherical in shape. According to a further preferred embodiment, at least one dampening weight of the present may preferably include a hollow, inner cavity. According to further aspects of the present invention, the dampening weight preferably may further include a granular material located within the inner cavity.Type: GrantFiled: November 14, 2018Date of Patent: January 26, 2021Assignee: Valmont Industries, Inc.Inventors: Carl J.
