Patent number: 9379644Abstract: Rotary motion devices (10) are provided. In one embodiment, the rotary motion devices (10) may comprise: a mass (12); a circumferential component (14); a plurality of spokes (16) connecting the mass (12) to the circumferential component (14), at least one of the spokes (16) comprising an electroactive polymer, wherein: the at least one spoke (16) has at least one input electrode and is configured to deflect upon application of an electrical potential across the at least one input electrode, and the rotary motion device (10) is configured such that deflection of the at least one spoke (16) causes the mass (12) to move, thereby causing the rotary motion device (10) to become off balance with respect to gravity, and rotate.Type: GrantFiled: June 23, 2011Date of Patent: June 28, 2016Assignee: Battelle Memorial InstituteInventors: Jay Sayre, Mark Stasik, Chuck Plaxico, Megan Moore, Vincent D. McGinniss, James Kennedy

Patent number: 6962245Abstract: Tunable pull-through energy attenuator and decelerator devices is disclosed which provide for variable force-time profiles, deceleration and kinetic energy attenuation of moving objects so as to prevent damage or injury to impacting objects, vehicles or persons. The device employs either consumable inelastic or reusable, viscoelastic deforming elements, such as tubes, rods, plates or strips, which absorb substantial amounts of energy through repeated inelastic or viscoelastic deformation when the deforming element is pulled-through a tunable array of rigid pins having a variety of configurations and settings. The disclosed devices provide for variable force-time profiles which control the cumulative deformation and thereby the amount of energy absorbed and rate of deceleration of impacting objects.Type: GrantFiled: May 22, 2003Date of Patent: November 8, 2005Assignee: Worcester Polytechnic InstituteInventors: Malcolm H. Ray, Chuck A. Plaxico
