Patent number: 11883090Abstract: Disclosed embodiments include apparatuses, systems, and methods for guiding a rotatable actuator along a helical path with a varied pitch to motivate an attached implement. In an illustrative embodiment, an apparatus includes an elongated implement movable along an axis and a rotatable actuator operably coupled with a proximal end of the implement to motivate the implement to move along the axis in response to rotation of the rotatable actuator. A guide is operably coupled with rotatable actuator, where the guide defines a generally helical channel around the axis to direct movement of a rotatable actuator, and wherein a pitch of the helical channel is varied to reduce a distance of travel of the actuator along the axis per unit of rotation of the actuator.Type: GrantFiled: December 9, 2020Date of Patent: January 30, 2024Assignee: Gyrus ACMI, Inc.Inventors: David A. Desmarais, Paul C. Leonard

Publication number: 20230248102Abstract: A garment worn by a wearer has an exterior shell and an interior shell with various impact absorbing material between the exterior shell and the interior shell. The impact absorbing material includes multiple structures, such as rods or filaments, capable of deforming when force is applied then returning to its state prior to application of the force. In various embodiments, a rate sensitive material (RSM) is positioned in one or more locations relative to the exterior shell and the interior shell of the garment to further attenuate impacts to the garment. The RSM changes its resistance to force based on a rate at which the material is loaded.Type: ApplicationFiled: September 13, 2022Publication date: August 10, 2023Inventors: Per Reinhall, Paul C. Leonard, Travis Edward Glover, Andre Hunter Paggao Stone, Anton Perry Alferness, Kurt V. Fischer, Gary S. Kaplan, John T. Dardis, II, Samuel R. Browd

Publication number: 20170196291Abstract: A garment worn by a wearer has an exterior shell and an interior shell with impact absorbing material comprising various structures between the exterior shell and the interior shell. When force is applied to the exterior shell, the structures of the impact absorbing materials deform (e.g., compress), reducing the force received by the interior shell. For example, the impact absorbing material forms structures such as multiple branched “Y” shapes or multiple cylindrical rods with a surface contacting the exterior shell and a surface contacting the interior shell. The interior of the rods and other impact absorbing structures may be filled with a deformable material, such as foam. The impact absorbing material may be formed into jacks, spherical shapes, bristles, intersecting arches, or other shapes positioned between the exterior shell and the interior shell.Type: ApplicationFiled: January 5, 2017Publication date: July 13, 2017Inventors: Travis Edward Glover, André Hunter Paggao Stone, Kurt V.
