The invention relates to a concrete access-denial bollard (1) for preventing access to vehicles, characterized in that it comprises means for wireless remote communication, in particular for connecting to an Internet network.

The present subject matter provides a gate for controlling passage of vehicles including: at least one first blocking element configured to swivel about a first pivot axis; and at least one second blocking element configured to swivel about a second pivot axis, wherein the first blocking element and the second blocking element are configured to swivel one opposite the other in a manner that a gap is formed between the first blocking element and the second blocking element, wherein the gap is set to allow or block passage of vehicles through the gap. Additional embodiments of the gate are disclosed herein.

Systems, methods, and software are provided for automated item restocking using gantry robots and establishing safety barriers for retail work operation spaces in retail store environments. Robot controllers in communication with the gantry robots and barrier robots direct the autonomous movements thereof for transferring items between customer-accessible point of sale locations and customer-inaccessible storage, and for alternately restricting and enabling access to work operation spaces, respectively.

An anti-breach bollard includes a steel hollow structural section (HSS) member having an interior and a longitudinal axis, and an elongated tubular-shaped structure disposed in the interior and extending generally parallel with the longitudinal axis, the elongated tubular-shaped structure having axially spaced openings.

A barrier system may include an impact receiving post having a solid cross section. The impact receiving post may be bendable and may have a proximal end and a distal end. A foundation cage may be coupled to the proximal end of the impact receiving post. The foundation cage may be configured for installation beneath a ground surface.

Embodiments are directed toward a spike strip. The spike strip preferably includes a housing, a plurality of spikes disposed in the housing, a door, and a mover. The door is preferably configured to transition between a closed configuration in which the spikes are covered and prevented from puncturing tires of vehicles driving over the spike strip and an open configuration in which the spikes are exposed and allowed to puncture a tire of a vehicle driving over the spike strip. The mover is preferably configured to transition the door from the closed configuration to the open configuration responsive to a signal provided to the spike strip from a remote location.

A bollard system includes a post extension to extend upward from a floor, a first collar to encircle the post extension, a first connector to encircle the post extension adjacent to the first collar, and a first handrail to be connected to the first connector. The bollard system includes a second connector to encircle the post extension adjacent to the first connector, a second handrail to be connected to the second connector, and a second collar to encircle the post extension adjacent to the second connector. The first collar is invertible selectively to a first lock position and a first release position, the first connector having greater freedom to rotate relative to the first collar when the first collar is in the first release position than when the first collar is in the first lock position.

A pass blocking apparatus includes a mechanism for permitting the intentional release of a blocking bar from a closed position to an evacuation position as necessary. The apparatus includes a blocking bar, hinge connection unit, biasing unit, and resistance unit. The blocking bar extends perpendicularly to the driving shaft axis, thereby swinging vertically by driving shaft rotation. The hinge connection unit connects the blocking bar to the driving shaft permits the blocking bar to swing horizontally from the closed to the evacuation position. The biasing unit applies a biasing force to the blocking bar, swinging the blocking bar toward the evacuation position. The resistance unit holds the blocking bar in the closed position against the biasing force. The resistance unit includes an electromagnetic device and a magnetic material, and generates the resistance force from a magnetic force by the electromagnetic device that attracts the magnetic material.
