Patent number: 11578467Abstract: A vehicle barrier apparatus and corresponding methods include a base and a vehicle receiving member coupled to the base and having proximal and distal ends. Also included is a deployable element rotatably coupled to the base and coupled to the vehicle receiving member at a mechanical coupler located closer to the distal end than to the proximal end. The deployable element is configured to receive a transfer force, from the vehicle receiving member, via the mechanical coupler, responsive to the vehicle receiving member receiving an applied force from a vehicle at the proximal end. The deployable element configured to deploy from a stored orientation to a deployed orientation responsive to the transfer force. Accordingly, vehicle force can be transferred and used to deploy the device effectively in a self-triggered configuration without hazards of stored energy.Type: GrantFiled: July 10, 2020Date of Patent: February 14, 2023Assignee: Viken Detection CorporationInventors: Gill W. McKenna, John P. Voccio, Peter J. Rothschild

Patent number: 5659277Abstract: A superconducting magnetic coil formed of anisotropic high temperature superconducting material includes ferromagnetic flanges positioned coaxial to the longitudinal axis of the coil and at the ends of the superconducting coil to capture magnetic flux emanating from the coil so that the maximum perpendicular magnetic field at the end regions is reduced. A reduction in the maximum perpendicular magnetic field increases the critical current at the end regions thereby increasing the critical current at these regions and maintaining an overall higher critical current of the coil.Type: GrantFiled: September 7, 1994Date of Patent: August 19, 1997Assignee: American Superconductor CorporationInventors: Chandrashekhar H.

Patent number: 5585772Abstract: An actuator in which a magnetostrictor is subjected to magnetic fields produced by a superconducting coil, and the magnetostrictor and coil are maintained at temperatures below the magnetic transition temperature of the magnetostrictor and the superconducting temperature of the coil, typically at temperatures in the range of about 4 to about 130 degrees Kelvin. The magnetostrictor is a laminated Terbium Dysprosium (TbDy) alloy structure and the coil includes high temperature superconducting oxide material. The laminations of the TbDy structure are mechanically loaded in compression and each has a thickness substantially equal less than or equal to the depth of field penetration, and a cooler maintains both the TbDy and superconductor at their optimum temperatures.Type: GrantFiled: January 11, 1995Date of Patent: December 17, 1996Assignee: American Superconductor CorporationInventors: Chandrashekhar H.
