An exemplary method associated with a crash gate configured to guard against motor vehicles crossing in a direction from an attack side to a protected side includes securing a buttress post assembly and a latch post assembly on opposite sides of a roadway, the buttress post assembly having two vertical buttress posts forming a barrier passage, the latch post assembly having two vertical latch posts forming a latch gap, and a vertical pin positioned in the latch gap; and mounting a moveable barrier in the barrier passage, the barrier including a rectangular frame with a horizontal gate beam extending from a buttress end to a latch end, the latch end including a hook open toward the protected side, wherein in a closed position the latch end is located in the latch gap.

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.

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.

A sentry-post bollard has one or more divergent photo eye units mounted pivotally within the bollard which emit their beams horizontally and across the width the doorway of a high-speed industrial door or other motorized door. The sentry-post bollard may be used to open the door, hold it open, or both, when a vehicle or person is detected approaching the doorway. The sentry-post bollard may be used as a safety device throughout a facility. Placed at intersections, dock doors, ramp doors, etc., a safety beacon or siren can be activated to warn pedestrians of oncoming motorized traffic. The photo eye units project their beam(s) through a window slot extending circumferentially along the bollard and having a width of a nominal three-quarter inch.

A collapsible boundary delineator includes a base for placement on a ground surface and a divider member that is movable relative to the base between a raised, operative position and a lowered, inoperative position. The base includes a pair of base members that are engageable with each other, and the divider member includes a pair of spaced apart ends secured one to each of the base members. When the base members are engaged together the divider member is in the raised, operative position and when the base members are disengaged from each other the divider member is in the lowered, inoperative position. A selectively releasable latch arrangement carried by the base members is movable between a latching position for selectively maintaining the base members in engagement with each other and a release position for selectively enabling the base members to be moved apart from each other.

The invention relates to a security barrier apparatus 10, 70, 100 comprising a support 12 having at least three upright posts 14, 16, 18, 72 thereon. Two of the posts 14, 18 being fixed to the support 12 and at least one post 16, 72 being translatably movable relative to the two fixed posts 14, 18. The two fixed posts 14, 18 being spaced apart from one another and comprise a first plane 19 therebetween. The movable post 16, 72 being mounted to a slide device 24 of the support 12 for providing said translatable movement. The slide device 24 to operate the apparatus 10, 70 between an open position and a closed position such that in the closed position the movable post 16, 72 is between the fixed posts 14, 18 for inhibiting the passage of a vehicle, and in the open position the movable post 16, 72 is out of alignment with the first plane 19 and adjacent to one of the fixed posts 14, 18 for allowing the passage of a vehicle therebetween.

A processor-implemented method and/or computer program product selectively blocks a self-driving vehicle's access to a roadway. A vehicle interrogation hardware device receives an autonomous capability signal from an approaching self-driving vehicle. One or more processors compare the predefined roadway conditions to current roadway conditions of the access-controlled roadway. In response to the predefined roadway conditions matching the current roadway conditions of the access-controlled roadway within a predetermined range, the processor(s) determine whether the level of autonomous capability of the approaching self-driving vehicle is adequate to safely maneuver the approaching self-driving vehicle through the current roadway conditions of the access-controlled roadway. In response determining that the level of autonomous capability of the self-driving vehicle is not adequate to safely maneuver the approaching self-driving vehicle through the current roadway conditions of the access-controlled roadway, an automatic barricade controlling device positions an automatic barricade to block the approaching self-driving vehicle from accessing the access-controlled roadway.

A barrier member including: a support; a first engagement member coupled to the support; and a translatable column defining a longitudinal axis, wherein the translatable column is rotatably and translatably mounted relative to the support, wherein the translatable column is translatable between: a first position in which the translatable column and the first engagement member are spaced apart from one another such that the translatable column is rotatable about said longitudinal axis; and a second position in which the translatable column and the first engagement member are engaged to prevent rotation of the translatable column about said longitudinal axis.

The present invention relates to an access control system for controlling access to an area secured by perimeter protection defining a secure perimeter. The access control system comprises a portable container configured to be stored, transported and installed repeatedly as a closed container. The portable container is further configured to be operated repeatedly as an open container and closed container with a permanent barrier section constituted by the portable container itself and configured to secure a perimeter. Furthermore the access control system comprises at least one operational barrier section configured to be operational in an open state to allow access through the secure perimeter to the area and in a closed state to block access through the secure perimeter to the area. The operational barrier section is configured to be fully contained within the closed container when not installed. Additionally, the operational barrier section is configured to operate outside of the portable container in either open state or closed state and to change between open state and closed state.

An extendable barrier system may be used to physically prevent motorists, bicyclists, pedestrians, or other traffic from passing a vehicle such as a bus, such as while passengers are embarking or disembarking. An extendable member may laterally extend from the vehicle in a non-telescoping manner. A motor driven sprocket may drive the extendable member, such as by engaging teeth that may be present on the extendable member. One or more retainers, such as rollers, may be fixed to the frame of the vehicle, and may guide the extendable member from a retracted position to an extended position. These rollers may be fixed in place, or may be allowed some degree of movement, so that if the extendable member is struck while in the extended condition, it may disengage from the vehicle without causing significant damage. A neutral switch may maintain the vehicle in neutral or park unless the member is retracted.
