Abstract: A barrier comprises a substantially horizontal portion, a substantially rigid ramp portion, a stabilization enhancer, a substantially vertical portion, and a connector portion. The substantially horizontal portion comprising a first side and a second side. The substantially rigid ramp portion is positioned on the first side of the horizontal portion to guide a rolling vehicle onto the horizontal portion. The stabilization enhancer is configured to distribute at least a portion of a groundward force of the rolling vehicle in an effective amount to prevent substantial horizontal movement of the barrier. The substantially vertical portion is positioned on the second side of the horizontal portion to impede movement of the rolling vehicle when traveling towards the second side of the horizontal portion from the first side of the horizontal portion. The connector portion is where the horizontal portion connects to the vertical portion.

Abstract: A shaped barrier comprises a substantially horizontal portion, a ramp portion, a substantially vertical portion, and at least one connector. The substantially horizontal portion is configured to increase the stabilizing force between the shaped barrier and the ground in an effective amount to prevent substantial movement of the shaped barrier by distributing at least a portion of a groundward force of a rolling vehicle on a receiving side of the shaped barrier. The ramp portion is configured to receive the rolling vehicle onto the horizontal portion. The substantially vertical portion is configured to impede the movement of the rolling vehicle. The at least one connector is configured to connect the shaped barrier with at least one other shaped barrier.

Abstract: A shell shaped barrier and methods thereof. A shell shaped barrier may be configured to increase the stabilizing force between the shell shaped barrier and the ground in an effective amount to prevent substantial movement of the shell shaped barrier by distributing at least a portion of a groundward force of a contact body on the receiving side of the shell shaped barrier. A shell shaped barrier may be configured to connect with one or more other shell shaped barriers. A shell shaped barrier may include one or more discontinuities between two or more shell shaped barriers. A shell shaped barrier may include a support member. A shell shaped barrier may include one or more stabilization enhancers. A shell shaped barrier may include one or more energy absorbers. A shell shaped barrier may contain, block and/or impede bulk material, flood material, mechanical objects.

Abstract: A joint for a structural space frame. The joint includes a first, outer hollow spherical member. The first spherical member fixedly receives the ends of the components of the space frame. A plurality of second members are disposed within the interior of the first spherical member. The second members each contact the first spherical member as well as two or more adjoining second members to provide a rigid joint.
