The present invention relates to a friction-increasing element for attachment to a roadblock, comprising: a friction-increasing element body for attachment to the roadblock, and at least one tapered contact edge, which tapered contact edge is carried by the friction-increasing element body such that the tapered contact edge is facing away from the friction-increasing element body. The invention also relates to a roadblock provided with a least one of such friction-increasing element.

A security device or apparatus for use with an ATM includes a pair of base assemblies selectively connected by a beam assembly. The beam assembly is designed to prevent access to one or more service doors of the ATM. In one version of the device the beam assembly includes a horizontally extending beam with vertically oriented posts extending from the beam. The device allows for the beam of the beam assembly to be moved from a locked position or state to an unlocked position or state. In the locked position access to the one or more service doors of the ATM is restricted or prevented, while in the unlocked position access to the one or more service doors of the ATM is permitted.

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.

The tire spiker with an extendable handle may comprise a pair of spike portions pivotally connected by a spring loaded hinge adapted to hold the spike portions in a deployed U-Shaped configuration to be deployed in front of and behind a tire in a traffic stop. An extendable handle on the frame may have a release button adapted to release a latch holding the spike portions together in a carry configuration. The spring loaded hinge urges the spike portions in a spaced, parallel orientation for surrounding a tire in a deployed configuration. The tire spiker with extendable handle is moved to a position whereby the two spike portions are in front of and behind a tire. The spike portions have upward oriented spikes adapted to puncture the tire if the tire rolls forward or backwards.

A structural barrier and energy absorbing device comprises a plurality of structural elements. The structural element alone or in a plurality may serve as a traversal impediment or energy absorbing device, such as a pedestrian barrier, vehicular barrier, anti-tank obstacle, ballistic barrier, or the like. The structural element may be a tetrapod such that it comprises an element body having four extension portions that extend outwardly from the interior center to a distal end, such that the structural element maintains an identical orientation and a low center of gravity in each of four resting positions. The structural element may be a solid-state structural element comprised of a particular material or a portable and collapsible structural element wherein the element body comprises an outer skin defining an interior void space, such that during set-up or installation the interior void space may be filled with a filler substance onsite.
