Abstract: A boom barrier includes a boom arm and a spring-assist module configured to assist with pivoting the boom arm. The boom arm can be pivoted upwardly to an upper position in response to torque being applied in a first direction to the boom arm. The boom arm can be pivoted downwardly to a lower position in response to torque being applied in a second direction to the boom arm. The spring-assist module can apply torque in the first direction to the boom arm when the boom arm is in the lower position and an adjacent range of intermediate positions to assist with pivoting the boom barrier upwardly and/or the spring-assist module can apply torque in the second direction to the boom arm when the boom arm is in the upper position and an adjacent range of intermediate positions to assist with pivoting the boom arm downwardly.

Abstract: A barrier apparatus includes a barrier post mounted to a base and extending upwardly from the base. A brace of the barrier apparatus is configured to restrict relative movement between the barrier post and the base. The brace can be mounted to the base so that it extends upwardly and obliquely toward the barrier post. The brace can include block. A reinforcing tube can extend around the block. A mated connection to the front of the brace can include a first mating protrusion extending into a first mating hole, and a mated connection to the bottom of the brace can include a second mating protrusion extending into a second mating hole. The brace or another brace can extend into a rear corner positioned between the barrier post and the base.

Abstract: An energy absorber includes a flexible tensile member having lengthwise sections arranged serially along a length of the flexible tensile member. Lengthwise sections define convolutions. Features are provided for both restricting straightening of the convolutions and automatically reconfiguring, in response predetermined tension in the flexible tensile member, to allow straightening of the convolutions.

Abstract: A shallow-mount, stand-alone security bollard includes a bollard post mounted to a base. The bollard post extends upwardly from within an interior space of the base. The base includes interconnected panels, including panels extending around the interior space of the base, and inner panels connected to the bollard post and dividing the interior space.

Abstract: An embedded housing system storing cables below the surface in a protected environment, with a moveable surface lid lying flush with the existing surface and following the crown or slope across the travel path. The cables are readily raised out of the housing structure to obstruct traffic across the travel path, or lowered into the housing system to allow unobstructed traffic passage. Single cables, multiple cables, and utility lines can be enclosed and remain protected within the housing support structure. Once raised, the cables can be attached to an end support. The housing support structure is prefabricated in sections, selectively attached to match the existing crown or slope across the travel path, and then installed below the surface. The flush surface lid of the cable housing structure is only about 8 inches wide, and can be locked while in the closed position. Surface lid sections remain connected while opening simultaneously across the sloping travel path, using an interlocking mechanism.

Abstract: A cable housing system includes a housing positioned below a travel path having a crown surface. A plurality of surface lid sections are connected to the housing. The surface lid sections generally lie flush with the surface crown of the travel path when in a closed position and define gaps between the surface lid sections when in an open position. A surface lid interlocking mechanism connects at least two adjacent surface lid sections, and an attachment mechanism provides for surface lid sections to be selectively moved relative to the housing.

Abstract: A barrier system prevents entry through a structure and includes a first door positioned across an opening in the structure on a first side of the structure and a second door positioned across the opening on a second side of the structure. A protection fabric extends over the second door such that the protection fabric is between the first door and the second door, wherein the protection fabric comprises at least one attachment eyelet along at least one edge of the protection fabric to attach the protection fabric to the structure. The protection fabric has cables that terminate in a series of the eyelets. The eyelets attach to stanchions mounted on a foundation and dissipate the force of impact of a projectile hitting the structure along the protection fabric and the stanchions.

Abstract: A light weight, high strength cable supported by a longitudinal device that is capable of stopping a 15,000 lb. vehicle at speeds exceeding 30 mph and provides for manual operation by one (1) person, whereas the barrier may pivot, move vertically, or swivel horizontally to control vehicle passage. During normal operations where the vehicle barrier is moved, there is no tension on the cable and it remains unfastened. If a vehicle impact occurs, the cable immediately engages and fastens to the end support structures to resist vehicle impact forces. The light weight cable and longitudinal support device also minimizes the counterweight size. The barrier may be moved by an operator from either side of the vehicle travel path. Both fixed and unfixed end support structures may be utilized.

Abstract: A light weight, high strength cable supported by a longitudinal device that is capable of stopping a 15,000 lb vehicle at speeds exceeding 30 mph and provides for manual operation by one (1) person, whereas the barrier may pivot, move vertically, or swivel horizontally to control vehicle passage. Typically, the cable is embedded within a longitudinal support device and remains concealed. During normal operations where the vehicle barrier is moved, there is no tension on the cable and it remains unfastened. If a vehicle impact occurs, the cable immediately engages and fastens to the end support structures to resist vehicle impact forces. The light weight cable and longitudinal support device provides span distances exceeding 24 feet across a vehicle travel path, while requiring only one (1) person to manually move the barrier. The light weight cable and longitudinal support device also minimizes the counterweight size. The barrier may be moved by an operator from either side of the vehicle travel path.

Abstract: An embedded housing system storing cables below the surface in a protected environment, with a moveable surface lid lying flush with the existing surface and following the crown or slope across the travel path. The surface lid includes lid sections extending from the housing with at least one lid section having at least one edge extending from the housing at an angle. The cables are readily raised out of the housing structure to obstruct traffic across the travel path, or lowered into the housing system to allow unobstructed traffic passage. The housing support structure is prefabricated in sections, selectively attached to match the existing crown or slope across the travel path, and then installed below the surface. Surface lid sections remain connected while opening simultaneously across the sloping travel path, using an interlocking mechanism. Rain water is inhibited from entering the housing support structure by the surface lid, but if it seeps inside, it will drain away by gravity.
