Read Time:1 Minute, 26 Second
Fifteen years ago I blogged about a different SQUID. Here’s an update:
Fleeing drivers are a common problem for law enforcement. They just won’t stop unless persuaded—persuaded by bullets, barriers, spikes, or snares. Each option is risky business. Shooting up a fugitive’s car is one possibility. But what if children or hostages are in it? Lay down barriers, and the driver might swerve into a school bus. Spike his tires, and he might fishtail into a van—if the spikes stop him at all. Existing traps, made from elastic, may halt a Hyundai, but they’re no match for a Hummer. In addition, officers put themselves at risk of being run down while setting up the traps.
But what if an officer could lay down a road trap in seconds, then activate it from a nearby hiding place? What if—like sea monsters of ancient lore—the trap could reach up from below to ensnare anything from a MINI Cooper to a Ford Expedition? What if this trap were as small as a spare tire, as light as a tire jack, and cost under a grand?
Thanks to imaginative design and engineering funded by the Small Business Innovation Research (SBIR) Office of the U. S. Department of Homeland Security’s Science and Technology Directorate (S&T), such a trap may be stopping brigands by 2010. It’s called the Safe Quick Undercarriage Immobilization Device, or SQUID. When closed, the current prototype resembles a cheese wheel full of holes. When open (deployed), it becomes a mass of tentacles entangling the axles. By stopping the axles instead of the wheels, SQUID may change how fleeing drivers are, quite literally, caught.
