Patent number: 9206616Abstract: Negative stiffness systems and methods for seismic protection of a structure is described. A system can include a negative stiffness device having a first linkage pivotably connected to an anchor frame at a first pivot point and pivotably connected the movement frame at a second pivot point. The negative stiffness device can include a spring having a first end operably coupled to the anchor frame and a second end operably coupled to a movement frame. In a rest state, the spring can be compressed to exert a preload force to the first linkage and the anchor frame and not displace the first linkage and the movement frame. In an engaged state, the spring can be configured to apply a force to the first linkage such that the movement frame is displaced in a same lateral direction of a seismic load. The spring force can be amplified by the first linkage.Type: GrantFiled: June 30, 2014Date of Patent: December 8, 2015Assignees: THE RESEARCH FOUNDATION FOR THE STATE UNIVERSITY OF NEW YORK, TAYLOR DEVICES, INC.Inventors: Apostolos A. Sarlis, Michael C. Constantinou, David A. Lee, Andrei M. Reinhorn, Douglas P. Taylor

Patent number: 8857110Abstract: A negative stiffness device and method for seismic protection of a structure is described. In one embodiment, the device has an anchor frame and a movement frame laterally translatable relative to the anchor frame. The anchor frame and movement frame have respective extension portions. A linkage is pivotably connected to the extension portion of the anchor frame. A compressed spring has a first end is attached to the extension portion of the movement frame and a second end attached to the linkage. The compressed spring has a spring force. In a rest state, the compressed spring does not apply a lateral force to the movement frame. In an engaged state, the compressed spring is configured to apply a lateral force to displace the movement frame in a lateral direction of a seismic load. The spring force is amplified by the linkage when the movement frame is laterally displaced to an amplification point.Type: GrantFiled: November 9, 2012Date of Patent: October 14, 2014Assignees: The Research Foundation for The State University of New York, William Marsh Rice University, Taylor Devices, Inc.Inventors: Michael C.

Patent number: 7901155Abstract: In order to stop a moving vehicle without injury to occupants, a vehicle barrier is provided having a pair of platforms disposed on opposite sides of a roadway, and a capture net extending across the roadway between the platforms. Each platform has a rotatably mounted spool attached to a different end of the net, and a dual acting extension-compression shock absorber pivotally mounted to the spool, such that when the force or energy of an impacting vehicle on the net is applied to the shock absorbers, via rotation of the spools. Rotation of spools operate the shock absorbers in compression, and if needed, in extension. In railroad crossing application, two of the vehicle barriers are provided on either side of the railroad tracks to prevent vehicles from crossing the railroad tracks.Type: GrantFiled: February 11, 2010Date of Patent: March 8, 2011Assignee: Taylor Devices, Inc.Inventor: John C. Metzger

Patent number: 5265552Abstract: A shock and vibration isolator for a member mounted on a body immersed in water including a housing, a rubber plunger mounted within the housing to define a chamber within the housing, vent apertures in the housing for permitting water to be pumped relative to the chamber in response to deflection of the rubber body, and a connector attached to the rubber body for mounting the member which is to be isolated from the body which is immersed in water, the rubber body and the associated chamber providing a combination of resilient and hydraulic support to thereby isolate the member from shock and vibration forces relative to the body.Type: GrantFiled: September 20, 1991Date of Patent: November 30, 1993Assignee: Taylor Devices, Inc.Inventor: Douglas P.
