Security From on High
A police helicopter crew has just finished rescuing a damsel from peril and chasing down a bad guy on the run. Job well done, and its time to head back to HQ. But theres no time to kick back for the ride home. The area was just hit by a major storm, so a bridge needs to be inspected for any damage. There have also been reports about a suspicious truck parked outside a nearby power plant. Better check it out with a flyover. Its a typical days work for members of the Maryland State Police Aviation Command. They conduct both emergency response and law enforcement missions from a fleet of helicopters. Yet these return missions can be time-consuming and complex to keep track of, especially when youre needed elsewhere in a hurry. Thanks to funding from the DHS Science and Technology (S&T) Directorate, however, the Maryland State Policeand agencies like it across the Nationnow have a quicker, easier, and cheaper way to conduct these kinds of inspections. Its called the Critical Infrastructure Inspection Management System (CIIMS). Developed at the State Polices request by the Johns Hopkins Applied Physics Laboratory, CIIMS will help flight crews efficiently manage their checks of vulnerable structures and sites, such as dams, bridges, and large industrial complexes. Heres how CIIMS works: Just before takeoff, a State Police flight crew loads data onto a handheld computer tablet, called an electronic flight bag. The data may include updated photos, coordinates, and maps for each critical infrastructure that needs to be inspected. This is all publicly available information, taken from Internet maps, navigation charts, and other sources. In addition to the geographic data, the tablet is loaded with a series of questions that the inspections are designed to answer. While flying over the site, a crew member uses touch-screen controls on the tablet to answer the questions based on his or her observations. Questions like: Do you see any cracks in the concrete at the base of the bridge? or Do you see a yellow truck parked outside the power plant? After the crew lands back at State Police headquarters, the data on the tablet are uploaded and sent to the proper authorities (a state or Federal agency). From that point on, the inspections can be filed, managed, and prioritized electronically, saving time and resources while improving homeland security. CIIMS is almost ready for primetime. The Maryland State Police will conduct further tests on CIIMS throughout the 2008 fiscal year and provide vital feedback to Johns Hopkins APL engineers, who will then tweak the system. Meanwhile, other state and local jurisdictions are expressing interest. Right now, were working with Maryland to really refine CIIMS, and then integrate the information collected by the tablets into a dependable reporting process, says Herb Engle, who manages the CIIMS project for the For more information about this story, click here Portable Pathology
If James Bond were a homeland security agent, Q would arm him with the BioBriefcase. If the villain Goldfinger ever tried to unleash deadly pathogens, Bond would flip off the lid of the BioBriefcase, quickly detect the germs, and notify authorities to limit any harm. Lives saved and evil In the real world, however, the villains are terrorists and the threat of a biological attack is far from fiction. Luckily, the BioBriefcase works in much the same way, and it really can save lives. Funded by the DHS Science and Technology Directorate, the BioBriefcase was developed by scientists and engineers at Lawrence Livermore and Sandia national laboratories. Its a product of a comprehensive DHS effort launched in 2003 to deploy a network of biomonitors, detectors, and warning systems. The Nation needs to be prepared in the event of an attack using a harmful or deadly biological agent, such as anthrax or another type of bacteria, virus, or toxin. BioWatch technologies are also significant products of this effort. (See the June 2007 issue of Snapshots.) The BioBriefcase is a portable option for the biodefense arsenal. Its only about the size of a large suitcase, and it can be placed in hard-to-reach areas such as air ducts. It can also conduct a bioanalysis within about an hour of receiving a sample, giving emergency responders a vital early warning of a possible attack. According to Lawrence Livermore, the BioBriefcase can play a critical role as an affordable tool for many kinds of civilian applications. It can be used by first responders, homeland security companies, and agriculture operations, or even for the purpose of environmental monitoring in factories or office buildings. Our team is particularly proud of the systems performance in field trials late last year, said Lawrence Livermore chemist Chris Bailey, who has directed much of the systems development. For the future, were looking for new opportunities for biological monitoring and further advancing the technology. The BioBriefcase uses state-of-art technologies to collect, process, and analyze samples. It can detect as well as identify genetic and protein signatures of agents. It can also be converted into a bench-top instrument for medical diagnosis and scientific research, with built-in capabilities for autonomous sampling and processing. Lawrence Livermore is looking for industry partners to help commercialize the BioBriefcase and, maybe, equip an army of James Bonds to take on the villains.

Want a device to see through walls, wood, concrete, earth, and steel? Scientists working for the DHS Science and Technology (S&T) Directorate looked around and found that nature sometimes comes in mighty handy. Take the lobster. Here you have a crustacean with an amazingly miniscule brain, yet this creature is able to see through walls of dense water obscured by silt and sand to find its food buried deep along the ocean bottom. Lobsters have limited image resolution, but possess high sensitivity and the ability to detect fast movement and the polarization of light. Over eons, this bottom crawler developed compound eyes to view its world through a large number of long, narrow square-shaped cells, arranged in a spherical array with a This is some eye-opening stuff. The eye that the LEXID is still very developmental, but it has some tremendous potential, says Jim Apple of Physical Optics Corporation of Torrance, CA, which built the technology under a Small Business Innovation Research (SBIR) grant. The Directorate has some tough specifications for this device. It must be able to see behind ship bulkheads, through several inches of soil, through steel, through wood beams, and through concrete. And, it must do this from about LEXID has sparked interest from the In the wake of the Whod have known wed get our inspiration from lobsters? adds Kirwin.
