We didn't even know we had a Homeland Security Advanced Research Projects Agency until the current issue of New Scientist arrived in our mailbox today:
The Homeland Security Advanced Research Projects Agency, the domestic equivalent of the defence agency DARPA, has launched an "innovative less-lethal devices for law enforcement" programme to radically expand the capabilities of electric shock weapons.We'll bet HSARPA is working on lots of other innovative ideas for crowd control as well. With any luck beta-testing will be finished by November, 2006, with the entire product line ready for rollout in 2008 -- right around the time of the Republican National Convention.
Existing stun weapons, such as the Taser, typically fire a pair of darts trailing current-carrying wires to shock the target, with a maximum range of about 7 metres. The HSARPA programme aims to develop wireless weapons that can be used over greater distances in spaces such as "an auditorium, a city street or a sports stadium".
Lynntech of College Station, Texas, is developing a projectile that can be fired from a shotgun or 40-millimetre grenade launcher. Grenade launchers are already used by riot police to fire tear gas and baton rounds. On impact, the device sticks to the target and delivers an 80,000-volt shock for 7 seconds, using a pulsed delivery similar to that used by Tasers. Further shocks can be triggered via remote control . . . .
Meanwhile, Midé Technology Corporation of Medford, Massachusetts, is proposing the Piezer. Rather than conventional stun-gun circuitry, with batteries linked to transformers and a capacitor, the Piezer contains piezoelectric crystals, which produce a voltage when they are compressed. The Piezer would be fired from a 12-gauge shotgun, stunning the target with an electric shock on impact. Shotguns are already used to fire less-lethal "beanbag" rounds to subdue suspects, but these have short range. Midé claims the Piezer could be effective at 40 to 50 metres.
Using a different principle again is the Inertial Capacitive Incapacitator (ICI) being developed by the Physical Optics Corporation of Torrance, California. It uses a thin-film charge storage device that is charged during manufacture and only discharges when it strikes the target. It can be incorporated into a ring-shaped aerofoil that can be fired from a standard grenade launcher at low velocity, while still maintaining a flat trajectory for maximum accuracy. The company claims this should reduce the impact force.
