When Your Ship Comes In
The world is a very different place out beyond the horizon. At any given time, some 40,000 large cargo ships are plying the worlds oceans, as are innumerable smaller merchant craft. They all pull in and out of ports, load, unload, change out crews and cargos, and steam from one location to the next. It can be an amazing, and trackless, storyrivaling Pirates of the Caribbeanto document how these ships come by and load their cargo, by what polyglot seamen and in what untamed ports. At any point in a merchant ships journey, pry open a container and what will you find? When you cant be sure, that spells danger. A single container gone purposefully astray and packed with explosives is not a fictional scenario. Enter MATTS, the Marine Asset Tag Tracking System. Equipped with a sensor, data-logging computer, radio transceiver, and GPS, MATTS is an inexpensive black box, no bigger than a deck of cards. Affixed to a container, it can store its location history and report it back when in range (up to MATTS can use its GPS chip to estimate its location even if the GPS signal is loststoring data like computer cookies. Once operational, when a MATTS tag is deep below deck, its transmitter signal will jump from one tagged container to the next until it finds a shipboard communications path. Soon, through research and development sponsored by the DHS S&T Directorate, MATTS will also be integrated with an Advanced Container Security Device, which will send alerts through MATTS when a container has been tampered with or opened.
MATTS was developed under an S&T Small Business Innovation Research (SBIR) contract by iControl Incorporated, a small Santa Clara, CAbased company. Were looking at a serious threat here, says Vinny Schaper, the SBIR Program manager. Eleven million containers a year are brought onto our docks. Interrupt this with a terrorist attack, and the backup would reach around the globe. This could be worldwide solution to a high-priority need, says Bob Knetl, who manages the MATTS research in the Directorates Borders and Maritime Division. In an April 2007 test, 100 MATTS-equipped containers started out in the Port of Yokohama, Japan, on their way to the Port of For more information about this story, click here Menace in a Bottle
Ever since the plot to blow up transatlantic airplanes with liquid explosives was uncovered in London last August, pressure has increased on the airline industryand the governmentto find new ways to not only detect liquids in baggage and on passengers, but also to figure out what those liquids are. Now, the S&T Directorate is teaming with scientists at The Directorate is testing a new airport baggage screening technology that can differentiate among a variety of liquids, gels, and lotions. Called SENSIT (for sense-it), it already can tell the difference between some Today, when you pack for the airport, you might have to place your toothpaste tubes, shampoo bottles, and cosmetics in a sandwich bag per the An interim step to this goal, Tait says, is to develop the capability to screen carry-on bags that are allowed under the SENSIT has thus far demonstrated the ability to differentiate more than four dozen materials considered safe for carrying onto airplanesfrom everyday personal items such as toothpaste and mouthwash to those that are considered hazardous. With the MRI signal, we want to distinguish between harmful items, and many common carry-on liquid consumables, says Tait. The goal is the reliable detection of liquids, with high throughput, that is non-contact, is non-invasive, requires no radiation, produces no residue, and uses the existing airport security portal. SENSIT is one of S&Ts Homeland Innovative Prototypical Solutions (HIPS)research that has moderate to high risk but considerable promise for high payoff. Were working hard on getting the SENSIT technology to an airport near you very soon, says S&Ts Innovation Director Roger McGinnis.

Unfortunately, some acts of kindness are far from random. They can be downright deadly. New homeland security research is showing how terrorist groups around the world develop strategic relationships with charity and humanitarian organizations in the very communities where they operate. In fact, these groups often fund or provide direct services such as medical care, wastewater treatment, and garbage collection, only to help build their legitimacy and recruit members for more acts of violence. They work to generate good will, says Shawn Flanigan, who traveled to Lebanon and Charities in the Middle East, for instance, may at first be hesitant to accept money or support from groups such as Hezbollah, which is known to advocate violence to achieve political goals. But over time, if the need for medical and other services becomes dire, they will move from passive acceptance to cooperation and, eventually, to full involvement in the cause. Some people [in the charities] will turn their heads at the violence, and others will say their religion calls them to be engaged with these groups, says Flanigan, now a professor at She also suggests a way to prevent terrorists from using charities: Help those same charities. If organizations have the supplies they need for their communitiesincluding the support of local and national governmentsshe says they will be less inclined to side with radical and violent groups. She recognizes, however, that such a change will not come overnight. As an example: While the Hezbollah-funded organization Jihad in Construction is listed as a terrorist front by the Flanigan conducted her research through funding from the National Consortium for the Study of Terrorism and Responses to Terrorism (START), a DHS Center of Excellence led by the University of Maryland. START is seeking to understand how radical and violent groups form and then persist. This knowledge, it says, can lead to effective ways to counter and prevent the spread of terrorism. Flanigan participated in STARTs Pre-Doctoral Fellow program, an annual competition that provides scholars with funds to support innovative research.

What will they think of next? That was the question facing government engineers at a recent test of robotic search-and-rescue technologies that may one day be used to save lives after a terrorist incident or natural disaster. Emergency responders from The goal was to put to the test robot performance using emerging standard test methods. The results will be used to develop usage guidelines that will match specific kinds of robots to particular disaster scenarios.

How does the LED Incapacitator incapacitate? By simultaneously overwhelming the subject both physiologically (temporarily blinding him) and psychophysically (disorienting him). A built-in rangefinder measures the distance to the nearest pair of eyeballs. Then, a governor sets the output and pulse train (a series of pulses and rests) to a level, frequency, and duration that are effective, but safe. The colors and pulses continuously change, leaving no time for the brain or eyes to adapt. After a few minutes, the effects wear off. The light could be used to make a bad guy turn away or shut his eyes, giving authorities enough time to tackle the suspect and apply the
There are often confrontations at border crossings with suspected illegal aliens or drug runners, Lieberman says. You dont want to hurt or kill them, just take them into custody. With this, he smiles, they dont need to know English to comply. Output and size can easily be scaled up to fit the need; immobilizing a mob, for instance, might call for a wide-angle bazooka version. Scaling down is more difficult. At This fall, in S&T Snapshots is a monthly newsletter produced by the DHS Science and Technology Directorate in partnership with the Homeland Security Institute.
