Inspired by bats, sensor technology detects dangerous structural cracks
Researchers have developed an ultrasound sensor for detecting dangerous cracks in structures such as aircraft engines, oil, and gas pipelines, and nuclear plants. The device, known as a transducer, identifies structural defects with varying ultrasonic frequencies and overcomes the limits of other, similar devices, which are based on rigid structures and have narrow ranges. It is thought to be the first device of its kind in the world.

U.S. Navy champions unmanned systems over, on, and under the sea
The presence of unmanned systems in the maritime military domain is growing, and the U.S. Navy has decided to make several organizational, and conceptual, changes in order to deal with unmanned systems in a more holistic fashion. Rear Adm. Robert P. Girrier has been named the Navy’s first director of unmanned weapon systems, and Secretary of the Navy Ray Mabus announced in April that he would appoint a new Deputy Assistant Secretary of the Navy for Unmanned Systems, “so that all aspects of unmanned — in all domains — over, on and under the sea and coming from the sea to operate on land — will be coordinated and championed.”

Counter-drone technologies demonstrated at DoD’s Black Dart event
Small, unmanned aircraft systems (UASs, aka UAVs, for unmanned aerial vehicle), or drones, are easy to obtain and launch and they are hard to detect on radar, making them of particular concern to law enforcement and the Department of Defense. Earlier this month DHS circulated an intelligence assessment to police agencies across the United States warning about drones being used as weapons in an attack. DOD says that Black Dart 2015, which began 26 July and ran through 7 August, is the Department of Defense’s largest live-fly, live-fire joint counter-UAS technology demonstration. One of the innovative developers of counter-UAS technologies is SRC Inc., a not-for-profit company formerly affiliated with Syracuse University. The company showed its SR Hawk surveillance radar, which is integral to its layered approach to defending against UASs.

Cars to harvest energy from bumps in the road
The 255 million cars on the road in the United States account for 40 percent of the country’s fuel consumption. Most of that fuel is wasted. Engineers may have a partial solution: harvesting energy from the car’s suspension. Only 10 to 16 percent of the fuel a car consumes is actually used to drive — that is, to overcome road resistance and air drag. Most of the rest is lost to heat and other inefficiencies. With clever engineering, however, that deficit can be reduced. Three major opportunities exist for recovering or generating energy while driving: the waste heat given off by the engine, the kinetic energy absorbed during braking, and the vibrational energy dampened by the shock absorbers.

Students race robot submarines in RoboSub competition
High school and college engineering students from across the globe competed for bragging rights and cash prizes at the 18th International RoboSub Competition, which wrapped up 26 July. The mission theme for this year’s contest played on the theme of the “Back to the Future,” movie trilogy. The individual autonomous underwater vehicle (AUV) had to navigate and complete an obstacle course — with tasks like “check the flux capacitor” and “travel through the time portal” — without human or computer interaction by team members.

New 3-D camera technology to uncover hidden landmines
It is estimated there are 110 million landmines buried across the world, with the potential to kill and maim innocent men, women, and children for decades to come. Yet landmine detection techniques have barely changed since the Second World War. The UN estimates that, using current technology, it would take more than 1,100 years to clear the estimated 110 million landmines situated in seventy countries. Researchers are exploring new landmine detection technologies.

Bomb-proof lining contains explosion in aircraft’s luggage hold
A bomb-proof lining developed by an international team of scientists has successfully contained blasts in a series of controlled explosions in the luggage hold of a Boeing 747 and an Airbus 321. The Fly-Bag, which lines an aircraft’s luggage hold with multiple layers of novel fabrics and composites, was tested last week under increasing explosive charges on disused planes. The tests, using this technology, have demonstrated that a plane’s luggage hold may be able to contain the force of an explosion should a device concealed within a passenger’s luggage be detonated during a flight.

Accelerometers embedded in ear tags detect disease in beef cattle
A smartphone switches its orientation from portrait to landscape depending on how it’s tilted. A car’s airbags inflate when it senses collision forces. By detecting earth’s vibrations, a computer can measure the magnitude and aftershocks of an earthquake. These technologies are made possible by accelerometers — small, electromechanical devices that measure acceleration. The devices are able to detect the most sensitive of motions, from the number of steps taken during a morning walk to the number of jaw movements during a heifer’s morning meal. In fact, some dairy producers use these devices to measure feed intake, detect heat and notably, identify sick animals.
