Abstract: A car-attack defending apparatus includes a pressure-sensitive reaction module, an emergent airbag-inflation module, a crash barrier module, and an integral exterior unit module, wherein the pressure-sensitive reaction module has a pressure-sensitive setting and triggering mechanism, the emergent inflation airbag module has an emergent airbag expansion mechanism, and the crash barrier module has a crash-resistant steel plate. The car-attack defending apparatus can be disposed at entrances of specific buildings or restricted areas, so that at the moment a suspected car ignores warning and attempts to access the site, the emergent airbag expansion mechanism will be triggered, by the weight of the car, so as to expand the airbag simultaneously, and to stretch the crash-resistant steel plate to form a barrier. As such, the suspected car can be prevented from moving further, allowing checkpoint personnel a safe standoff distance from car bombs.

Abstract: A vehicle arresting device comprises a net intended to be laid flat on the ground in the path of a target vehicle with an array of upwardly-directed spikes attached to the net along a leading portion, so that when a vehicle runs over the device some of the spikes engage in its front tires and the net is caused to wrap around the front wheels, being pulled tight under the vehicle to prevent further rotation of those wheels. There are two rows of spikes, with the spikes in the second row being substantially longer than the spikes in the leading row. The gauge of the netting also varies, with the leading strip which includes the shorter spikes and back towards the longer spikes being of a thinner gauge, the portion from the longer spikes back to approximately the mid length of the net being of a thicker gauge, and the trailing portion reverting to the thinner gauge. These measures help to ensure that the net is capable of arresting a wide range of vehicles, from passenger cars to trucks.

The refection side, the impact side, and the plurality of interior walls are formed from vertically-oriented sheets of barrier material (when in the deployed configuration).

Abstract: An energy absorbing terminal is described that is made up of a plurality of cells partially defined by cambered panels made of thermoplastic or another suitable material. The panels are supported upon rectangular frames. The cambered portion of the panels provides a predetermined point of flexure for each panel and, thus, allows for energy dissipation during a collision. The stiffness of the crash cushion may be varied by altering material thicknesses and diaphragm spacing. In operation, a vehicle colliding in an end-on manner with the upstream end of the energy absorbing terminal will cause each of the cambered panels to bend angularly at its point of flexure and, thus, cause the cells to collapse axially. The use of thermoplastic, such as polyethylene results in a reversible, self-restoring collapse for the terminal, meaning that the terminal is reusable after most collisions.

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: A device when activated, disables a fleeing vehicle from within the operator's vehicle. The device mounts directly to the operator's vehicle. This device is controlled by the operator from within the vehicle by way of a control panel. When deemed necessary, the system is armed using a switch mounted on said panel. This allows for deployment upon activation of said switch. Upon positioning of operator car, the switch is activated, extending spike strip laterally. This places the spike strip under the pursued vehicle, in front of one or more of the tires. The operator applies the brakes of said vehicle, causing the spike strip to travel under the pursued vehicle's tire, disabling the vehicle. Upon traveling under the tire, the operator removes pressure from switch, causing the unit to safely stow itself. The system can then be re-deployed at will.
