• AIRPORT SECURITYImproving the Speed and Safety of Airport Security Screening

    By Anne McGovern

    For decades, airports around the nation have employed sensitive canine noses to detect concealed explosives. While this four-legged fleet has been effective and efficient, researchers have yet to build a mechanical method that can mimic their abilities. Researchers seek ways to build non-contact screening methods that can detect concealed explosives at airports.

  • EXPLOSIVE DETECTIONThe Next Generation of Explosives Trace Detection is Here

    Launched in fiscal year 2020, NextGen Explosives Trace Detection (ETD) expands the scope of aviation checkpoints technology, resulting in the advancement of technologies that can quickly and accurately collect and analyze samples in a variety of ways, including from direct contact with the subject, non-contact sampling via vapors, and even through barriers.

  • EOD/IED & COUNTERMINE INITIATIVESIdentifying and Neutralizing New Explosive Threats

    The IED threats from insurgent characterized the wars in Afghanistan and Iraq, but now the U.S. military is focusing on neutralizing bombs and mines that it could face in future conflicts against more advanced adversaries. DSI October 2022 EOD/IED & Countermine Symposium will highlight current initiatives toward identifying and neutralizing explosive threats to the homeland and critical infrastructure.

  • DETECTIONDeep Learning Technology for Faster and More Accurate Terahertz Security Inspection

    With the strengthening of global anti-terrorist measures, it is increasingly important to conduct security checks in public places to detect concealed objects carried by the human body. A new detection method can be used for accurate and real-time detection of hidden objects in terahertz images. 

  • AIRPORT SECURITYRemote Screening Demonstration at Cape Cod Gateway Airport

    DHS S&T successfully conducted a demonstration of remote screening infrastructure for airport security checkpoints. The Integrated Defense & Security Solutions (IDSS) can send computed tomography (CT) X-ray images of carry-on baggage flagged for threats to remote locations for near real-time analysis.

  • EXPLOSIVES DETECTION3D X-Ray Makes it Easier to Detect Hidden Explosive Weapons

    As travelers pass through border crossings, ports of call, airport checkpoints, and various precautionary measures in both federal and private venues, their safety and wellbeing are constantly ensured through various forms of screening technologies that have one critical goal: to identify and alert the proper authorities to potential threats. These technologies do their jobs very effectively, but it is important to ask the question: Can they be improved?

  • AIRPOR SECURITYComputer Code to Speed Up Airport Security

    Imagine moving through airport security without having to take off your shoes or belt or getting pulled aside. Researchers are working on the Open Threat Assessment Platform, which allows the Transportation Security Administration to respond more quickly and easily to threats to air travel safety.

  • BOMB SQUADSDIY Innovations for Bomb Squads

    Bomb-squad members must effectively employ critical thinking and problem-solving skills while working in stressful, potentially life-threatening situations. DHS S&T notes that bomb technicians’ ability to expect the unexpected and adjust accordingly has created a consistent pipeline of do-it-yourself (DIY) inventions to solve everyday issues they face, and the S&T works to validate these innovations.

  • AIRPORT SECURITYOpening Architecture to Make Air Travel Safer, Easier

    By J. C. Ross

    Researchers have developed an open architecture for airport screening systems, which will allow air travelers to experience faster and safer security checkpoints — no need to open bags or remove liquids or shoes.

  • SOFT TARGETSConsortium to Combat Targeted Crowd Attacks

    Ten universities formed a consortium to combat terrorist and criminal attacks on soft targets such as schools, hospitals, shopping malls and sports stadiums. “The challenges of keeping people safe in soft targets and crowded spaces gets more complicated every day,” said one expert.

  • AVIATION SECURITYAviation Self-Screening Concept and Prototype

    DHS S&T has awarded $2.5 million to Vanderlande Industries to develop a passenger self-screening concept design and prototype that streamlines TSA PreCheck operations.

  • Weapons DetectionWeapons-Detection Algorithm Studied at Las Vegas International Airport

    This summer, DHS S&T demonstrated a new advanced algorithm to better detect non-explosive weapons like guns, knives, and other items that are prohibited on commercial aircraft in a real-world setting at Las Vegas’ McCarran International Airport.

  • ExplosivesHow Big Was the 2020 Beirut Explosion?

    On 4 August 2020, one of the largest non-nuclear explosions in history pulverized a Beirut port and damaged more than half the city. The explosion resulted from the detonation of tons of ammonium nitrate, a combustible chemical compound. The explosive yield estimates varied widely, and in some cases, were inconsistent with what would be expected based on the amount of ammonium nitrate stored at the Beirut harbor.

  • Explosives detectionImaging Tool under Development Reveals Concealed Detonators — and Their Charge

    A Sandia Lab researcher is working on building a new kind of neutron-based imaging system which will enable people to safely examine sealed metal boxes when opening them could be dangerous, whether this is because inside is an explosive weapon or a malfunctioning, high-voltage fire set at a missile range.

  • Port securityEnsuring Reliability of Air Cargo Screening Systems

    DHS, which is responsible for ensuring the security of air cargo transported to the United States, says the threat from explosives in air cargo remains significant. A new GAO report addresses how DHS secures inbound air cargo, and the extent to which TSA’s field assessment of a CT screening system included key practices for design and evaluation.
