A containment device including a dry curtain, adapted to be deployed for the containment or re-containment of a discharge area, such as an opening, e.g. a door, in response to an explosion. The device includes a ballast bar in the lower portion of the curtain, the ballast bar including cylinders of high-density foam alternated with cylinders of compressible low-density foam.

A vehicle arrestor system includes a ditch box defined by a pair of opposing side walls and a bottom wall extending between the side walls forming a chamber therebetween. A movable plate forms at least a portion of a top wall of the chamber. A mechanical actuator is operably coupled to the movable plate for causing the movable plate to move between a non-actuated position and an actuated position. The movable plate is flush with the road pavement when in the non-actuated position and is not flush with the road pavement when in the actuated position. The vehicle arrestor system serves a dual purpose of arresting movement of a vehicle and providing a notification to a driver of the vehicle to slow down if the vehicle is exceeding the posted speed limit. A plurality of vehicle arrestor systems can be strategically placed in a locked island arrangement.

A blast resistant barrier system includes a base, a support structure extending outward from the base, a protective barrier that is pivotally coupled with the support structure at a first point of the protective barrier, and a shear pin that is configured to couple a second point of the protective barrier to the support structure so as to constrain rotation of the protective barrier relative to the support structure. The shear pin is configured to shear upon a threshold amount of force being applied to a face of the protective barrier. Once the shear pin shears, the protective barrier is permitted to rotate relative to the support structure about the first point.

A barrier system is configured to stop vehicular traffic. The barrier system has a beam gate arranged between a first barrier and a second barrier. The beam gate further comprises a hollow beam having bean first end and a beam second end. A beam cable is arranged through the beam along a beam central axis. A latch assembly has a cradle assembly that is joined to the first barrier and configured to house the beam in the cradle assembly. A pivot arm is joined to the beam and the second barrier, and further has a pivot arm joined to an axle and a counterweight housing. The counterweights arranged on the counterweight housing facilitate raising and lowering the beam in order to stop vehicular traffic.

A gate for controlling oncoming traffic on a roadway (e.g. a highway). The gate comprises an arm movable between an extended position in which the arm extends into a given portion of the roadway to inform the oncoming traffic that the given portion of the roadway is closed and a retracted position in which the arm does not extend into the given portion of the roadway and thus leaves open the given portion of the roadway for the oncoming traffic. The gate also comprises a control system comprising an actuator and configured to support the arm and move the arm between the extended position and the retracted position. The arm may be quite long and vertically wide to close more of the roadway and be clearly visible to the oncoming traffic, while the gate may be crash-tested (i.e., compliant with crash-testing criteria), the control system may be compact, and the gate may be reusable and easily repairable if crashed into.

A crash gate assembly includes a buttress post assembly secured in the ground and having two vertical buttress posts forming a barrier passage, a latch post assembly secured in the ground on the opposite side of a roadway from the buttress post assembly, the latch post assembly including two vertical latch posts forming a gap, and a barrier including a horizontal gate beam disposed in the barrier passage and extending from a buttress end to a latch end, the barrier slidingly positioned in a closed position with the barrier extending across the roadway and the latch end disposed in the latch gap.

An end treatment array for crash attenuation includes a transition barrier module formed of side walls, end walls, a top wall, and a bottom wall, wherein the module walls together define an enclosed interior space. The end treatment array further includes a containment impact sled having an axially extending frame. The frame has a width sufficient to contain the transition barrier module within the frame when in an assembled configuration, and has an axial length which is at least one-half the length of the transition barrier module. The frame defines an interior volume, the purpose of which is to contain a substantial portion of the transition barrier module in the assembled configuration, and to contain debris caused by destruction of the plastic barrier modules in a vehicular impact. The containment impact sled is attached to the transition barrier module.

An electric vehicle charging station parking block. In one aspect, the parking block includes a top surface and a bottom surface. The bottom surface is configured to be closer to the ground than the top surface when the parking block is in an installed state. The parking block has a cord channel defined at a location within the parking block that is between the top surface and the bottom surface. The cord channel is a void configured to accept a cord that connects an electric vehicle (EV) charger to an EV charging port configured to physically connect to an EV.
