  • SurveillanceLarge robotic jellyfish to patrol the oceans

    The Office of Naval Research wants to place self-powering, autonomous machines in waters for the purposes of surveillance and monitoring the environment, in addition to other uses such as studying aquatic life, mapping ocean floors, and monitoring ocean currents. Researchers have built a device for that purpose — a life-like, autonomous robotic jellyfish the size and weight of a grown man, 5 foot 7 inches in length and weighing 170 pounds.

  • Law-enforcement technologyLicense plate scanners in Canada under fire from privacy commissioners

    British Columbia’s privacy commissioner is not happy about the way police departments are using their license-plate scanners; in a report released last week, Commissioner Elizabeth Denham said changes must be made to the Victoria police department’s Automated License Plate Recognition Program (ALPR), after it was discovered that the program could be used as a surveillance tool

  • SurveillanceDARPA seeking surveillance technology to predict future behavior

    DARPA has teamed up with scientists from Carnegie Mellon University to create an artificial intelligence system that can watch and predict what a person will “likely” do in the future, using specially programmed software designed to analyze various real-time video surveillance feeds; the system can automatically identify and notify officials if it recognized that an action is not permitted, detecting what is described as anomalous behaviors

  • Oil leaksNew fluorescence technology pinpoints oil leaks at sea

    Cambridge Consultants uses fertility monitor technology in oil leak early warning system; the company has built an oil spill detection technology platform which is capable of detecting the natural fluorescence of even tiny amounts of oil in or on water

  • DetectionRadiation-enabled computer chips allow low-cost security imaging systems

    With homeland security on high alert, screening systems to search for concealed weapons are crucial pieces of equipment; these systems, however, are often prohibitively expensive, putting them out of reach for public spaces such as train and bus stations, stadiums, or malls, where they could be beneficial; until now

  • Border securityDHS submersible Pluto mimics the real narco-subs

    In the early 1990s, South American drug cartels came up with a new tactic to transport narcotics destined for the United States: small, radar-dodging, self-propelled, semi-submersibles (SPSSs); better to address the submersible problem, DHS Science and Technology Directorate created its own submersible and called it Pluto, after the planet which is difficult to spot

  • BusinessRemote monitoring market exceeds $29 billion in 2011

    A new reports says that the world market for remote monitoring services was worth more than $29 billion in 2011, equivalent to $2.4 billion in recurring monthly revenues (RMR) across the year; the report also estimated that, in the same year, 54 million accounts, or customer locations, were provided with services

  • Border securityDHS seeks better ways to detect ultra light aircrafts used by smugglers

    As the war on drugs continues with every sunrise and sunset, DHS has awarded a contract just short of $100 million for a specialized system which will be able to detect ultralight aircrafts which are used to smuggle drugs across the border

  • BlimpsWorld’s largest blimp passes flight test

    The world’s largest, lighter-than-air, optionally piloted aircraft — the U.S. Army’s Long Endurance Multi-Intelligence Vehicle (LEMV) – completed its first test flight in Lakehurst, New Jersey, the birthplace of the U.S. storied military airship past; the LEMV will provide improved ISR capabilities to the U.S. Army in the form of an “unblinking stare” over ground troops, ranging anywhere from one day to multiple weeks

  • BlimpsFirst class of U.S. Army soldiers completed training with Raytheon's JLENS

    JLENS uses a powerful integrated radar system to detect, track, and target a variety of threats, allowing military units to defend against threats, including hostile cruise missiles, low-flying manned and unmanned aircraft, large caliber rockets, and moving surface vehicles such as boats, SCUD-launchers, automobiles, and tanks

  • SurveillanceNYPD, Microsoft develop and deploy new surveillance system

    The New York Police Department (NYPD) and Microsoft have teamed up to create the Domain Awareness System, which will analyze real-time safety data for use by NYPD investigators; the system will act as a communications hub which will allow a number of advanced counterterrorism systems to relay information to more than 1,000 people in the field

  • WaterEngineers solve leaky water pipes problem

    Leaky pipes are a common problem for the water industry: according to the U.K. Water Services Regulation Authority (OFWAT), between 20 and 40 percent of our total water supply can be lost through damaged pipes; developing more accurate ways of finding leaks would enable water companies to save revenue and reduce their environmental impact

  • DetectionSeeing through walls with the help of laser systems

    Inspired by the erratic behavior of photons zooming around and bouncing off objects and walls inside a room, researchers combined these bouncing photons with advanced optics to enable them to “see” what is hidden around the corner

  • DetectionSeeing through walls, clearly

    Research and tests show, for the first time, the ability to use t passive WiFi radar for through-the-wall (TTW) detection of moving personnel – and do so covertly

  • Infrastructure protectionNew, affordable instant warnings of bridge collapse

    The Federal Bureau of Transportation lists nearly 70,000 U.S. bridges as “structurally deficient,” requiring extra surveillance; in addition, more than 77,000 others are categorized as “obsolete” — exceeding their intended lifespan and carrying loads greater than they were designed to handle; researchers developed a new technology for monitoring these 150,000 aging U.S. highway bridges
