Harness-Mounted Computer Improves Communication Between Dogs and Humans

North Carolina State University researchers have developed a suite of technologies that can be used to enhance communication between dogs and humans. The communication tool enables applications in search-and-rescue operations and pet training. “We’ve developed a platform for computer-mediated communication between humans and dogs that opens the door to new avenues for interpreting dogs’ behavioral signals and sending them clear and unambiguous cues in return,” says Dr. David Roberts, an assistant professor of computer science at NC State and co-lead author of a paper on the work. “We have a fully functional prototype, but we’ll be refining the design as we explore more and more applications for the platform.”The platform itself is a harness that fits comfortably onto the dog, and which is equipped with a variety of technologies.“Dogs communicate primarily through body language, and one of our challenges was to develop sensors that tell us about their behavior by observing their posture remotely,” Roberts says. “So we can determine when they’re sitting, standing, running, etc., even when they’re out of sight." A harness-mounted computer transmits data wirelessly. The technology also includes physiological sensors that monitor things like heart rate and body temperature. The sensors not only track a dog’s physical well-being, but can offer information on a dog’s emotional state, such as whether it is excited or stressed.SourceAlso: Learn about a Communication Monitoring System for Enhanced Situational Awareness.

Thirsty? There’s an App for That

Clean, potable water is one thing the world universally cannot live without. It hydrates. It cleans. It keeps us alive and well. That makes water very valuable to soldiers. However, as many mission planners know, water planning can be a nightmare. Too much water can strain already heavy combat loads, perhaps forcing some soldiers to pack too little in favor of a lighter pack. When soldiers don't have enough water, dehydration could set in, decreasing performance and increasing the risk of serious heat illnesses. To help solve this logistical problem, researchers from the U.S. Army Research Institute of Environmental Medicine’s (USARIEM) Thermal and Mountain Medicine Division and Massachusetts Institute of Technology’s Lincoln Laboratory worked to develop an app that will help unit leaders accurately predict water needs with the goal of minimizing the burden of water transport and sustaining hydration. The app is designed to satisfy the military’s desire for paperless guidance that is simple, accurate, mission-specific and available in real time.

Project Could Detect Damaged Aircraft Parts Earlier and Easier

UT Arlington engineering professors have received a $451,781 Air Force Office of Scientific Research grant to examine the material surface at the micro- and nano-scale level to provide clues for predicting fatigue in aircraft parts. Haiying Huang, professor of Mechanical and Aerospace Engineering, said the new technology and process would be better and more efficient than taking X-rays of an aircraft’s wing.

University Opens New Ballistics and Impact Dynamics Lab

Wichita State University’s National Institute for Aviation Research recently opened a new ballistics and impact dynamics research lab in the former Britt Brown Arena at the Kansas Coliseum. The new ballistics lab, part of NIAR’s environmental Test Labs, uses a custom built ballistic firing device to propel 22-50 caliber rounds into components inside a concrete containment building. The test is designed to simulate the impact of a structural failure on the aircraft.

2-in-1 Motor Increases Range of Electric Cars

Scientists from Nanyang Technological University (NTU) and German Aerospace Centre (DLR) have invented a 2-in-1 electric motor that increases the range of electric vehicles. The engine integrates the traditional electric motor with the air-conditioning compressor, typically two separate units. This novel, space-saving design allows the use of bigger batteries, which can increase the range of electric vehicles by an additional 15 to 20 percent.

Engineering More Efficient Vehicle Powertrains

More than 60 percent of the energy generated in vehicle engines by fuel is lost through the exhaust gas and the coolant. The biggest part of this simply slips off into the environment as heat. The Fraunhofer Institute for Chemical Technology ICT is probing the causes for this kind of waste. It is developing efficient drive concepts for vehicles, and has succeeded in increasing the degree of efficiency of car engines by five percent, and up to ten percent for commercial vehicle powertrains.

Pulley Mechanism Improves Hand Function After Surgery

Engineers at Oregon State University have developed and successfully demonstrated a simple pulley mechanism to improve hand function after surgery. The device is one of the first instruments ever created that could improve the transmission of mechanical forces and movement while implanted inside the body.
