Border Patrol: Checkpoints Contribute to Border Patrol's Mission, but More Consistent Data Collection and Performance Measurement Could Improve Effectiveness
A letter report issued by the Government Accountability Office with an abstract that begins "The U.S. Border Patrol, part of the Department of Homeland Security's Customs and Border Protection (CBP), operates checkpoints on U.S. roads, mainly in the southwest border states where most illegal entries occur. As part of a three-tiered strategy to maximize detection and apprehension of illegal aliens, Border Patrol agents at checkpoints screen vehicles for illegal aliens and contraband. GAO was asked to assess (1) checkpoint performance and factors affecting performance, (2) checkpoint performance measures, (3) community impacts considered in checkpoint placement and design, and (4) the impact of checkpoint operations on nearby communities. GAO work included a review of Border Patrol data and guidance; visits to checkpoints and communities in five Border Patrol sectors across four southwest border states, selected on the basis of size, type, and volume, among other factors; and discussions with community members and Border Patrol officials in headquarters and field locations."

Application of the smart portal in transportation
Under a program sponsored by the Department of Energy, the Oak Ridge complex is developed a ``Portal-of-the-Future``, or ``smart portal``. This is a security portal for vehicular traffic which is intended to quickly detect explosives, hidden passengers, etc. It uses several technologies, including microwaves, weigh-in-motion, digital image processing, and electroacoustic wavelet-based heartbeat detection. A novel component of particular interest is the Enclosed Space Detection System (ESDS), which detects the presence of persons hiding in a vehicle. The system operates by detecting the presence of a human ballistocardiographic signature. Each time the heart beats, it generates a small but measurable shock wave that propagates through the body. The wave, whose graph is called a ballistocardiogram, is the mechanical analog of the electrocardiogram, which is routinely used for medical diagnosis. The wave is, in turn, coupled to any surface or object with which the body is in contact. If the body is located in an enclosed space, this will result in a measurable deflection of the surface of the enclosure. Independent testing has shown ESDS to be highly reliable. The technologies used in the smart portal operate in real time and allow vehicles to be checked through the portal in much less …
