Abstract: A security barrier system for use with a trafficable surface and a site requiring protection from advancing vehicles includes a composite bed system having a plurality of elevations and comprising a first layer beneath a second layer. The first layer includes a deformable material configured to collapse when subjected to vehicle loads, and the second layer includes a pedestrian cover surface over the deformable material that conceals the deformable material. The pedestrian cover surface is configured to support pedestrian traffic over the deformable material without permanently collapsing the deformable material and to collapse along with the first layer when subjected to vehicle loads. A structure beyond the bed system is provided to resist the impact of a vehicle that has traversed the bed system.

Abstract: A training tool for use by lacrosse players attaches a player's hand or glove to the lacrosse stick. Lacrosse players typically have a dominant hand orientation which they play with, and the development skills in the non-dominant hand orientation is of particular interest. This tool will attach the player's glove to the player's stick in their non-dominant hand orientation, allowing their gloves to slide up and down on the stick, but preventing the player from switching the player's hand orientation, in order to force the use of a non-preferred stick orientation which will strengthen the overall level of a player's skill set.

Abstract: A security barrier system for use with a trafficable surface and a site requiring protection from advancing vehicles includes a visual indicator element having an appearance that is distinctive from the trafficable surface and disposed adjacent to the trafficable surface. A composite bed system includes a first structure beneath a second structure, where the first structure includes a deformable material that collapses under vehicle loads, and the second structure includes a pedestrian cover surface of a different material over the deformable material that conceals the deformable material and supports pedestrian traffic over the deformable material without permanently collapsing the deformable material. A pedestrian sidewalk is located between the bed and the visual indicator element, and a containment structure contains the bed system and resists the impact of a vehicle that has traversed the bed system.

Abstract: An adaptable barrier system protects a site of value that is adjacent to a trafficable surface, from impact by a vehicle. The system includes traffic patterns to reduce speed, followed by a first impact element that causes a vehicle to become elevated from the trafficable surface. A bed having a deformable structure or material beyond the first impact element lowers the elevation of a vehicle that encounters the bed. A cover overlies the compressible material to allow passage of pedestrians and lightweight vehicles. An impact element line beyond the bed has sufficient height to impact a chassis of the vehicle having an elevation that is lowered by the bed, and prevent further progress of the vehicle. The combination of the first impact element, the bed and the impact elements line may be reproportioned with respect to each other to provide a barrier intended to suit a particular application.

Abstract: An operable barrier system for vehicles includes a turntable for use with a trafficable surface and at least one impact element disposed on the turntable. A drive system is provided to rotate the turntable along the trafficable surface between a first position to prevent passage by vehicles and a second position, approximately 90 degrees from the first position, to permit passage by vehicles. A method of providing an operable vehicle barrier for use with a roadway includes providing a turntable device having a top surface, mounting at least one impact element on the top surface, and providing a drive system capable of rotating the turntable device in a plane that can be driven across by vehicles from the roadway.

Abstract: A barrier system for use with a trafficable surface that penetrates a boundary to control access by vehicles and to permit uncontrolled access by pedestrians. The system includes a turntable providing a surface that is rotatable generally in the plane of the trafficable surface. Impact elements are arranged along the surface in a pattern having a spacing configured to permit passage by pedestrians and to prevent passage of vehicles when the turntable is in a first position and to permit passage of vehicles when the turntable is rotated to a second position. The system controls vehicle traffic across the boundary by moving the turntable between the first position and the second position.
