This innovation is capable of correlating two analog signals by using an analog- based signal conditioning front end to hard-limit the analog signals through adaptive thresholding into a binary bit stream, then performing the correlation using a Hamming “similarity”...

Application-specific-integrated-circuit (ASIC) design for space applications involves multiple challenges of maximizing performance, minimizing power, and ensuring reliable operation in extreme environments. This is a complex multidimensional optimization problem, which...

The objective of this effort was to develop a non-toxic, non-flammable, –80 °C phase change material (PCM) to be used in NASA’s ICEPAC capsules for biological sample preservation in flight to and from Earth orbit. A temperature of about –68 °C or lower is a critical temperature for...

Researchers have learned that running cockroaches recover from a shove before their dawdling nervous system kicks in to tell their legs what to do. These new insights on how biological systems stabilize could one day help engineers design steadier robots and improve doctors' understanding of human gait...

A new method of harvesting the Sun's energy is emerging, thanks to scientists at UC Santa Barbara's Departments of Chemistry, Chemical Engineering, and Materials. Though still in its infancy, the research promises to convert sunlight into energy using a process based on metals that are more...

Researchers at Brown University have developed a robotic bat wing that provides valuable new information about dynamics of flapping flight in real bats. The robot, which mimics the wing shape and motion of the lesser dog-faced fruit bat, is designed to flap while attached to a force transducer in a wind tunnel.

Last month, the U.S. Food and Drug Administration cleared iRobot's RP-VITA telepresence robot for operation in hospitals. Controlled by an iPad interface, the RP-VITA allows doctors to virtually "visit" patients and staff remotely. Similarly, it was reported this month that a boy...

Simple blast fences called baffles could deliver improvements in air quality for people living near airports, new research has found. Placed behind a runway, the baffles could serve as a “virtual chimney,” funneling emissions from aircraft engines upwards where they can...

The National Center for Atmospheric Research (NCAR) has developed a prototype system to help flights avoid major storms as they travel over remote ocean regions. The 8-hour forecasts of potentially dangerous atmospheric conditions are designed for pilots, air traffic controllers, and others...

The Air Force Civil Engineer Center, in conjunction with the Air Force Research Laboratory, recently introduced a first-of-its-kind runway rubber removal system for use at remote airfields. The device, which uses a retrofitted Unimog designed for transport to airfields in austere areas of Southwest Asia,...

A quick, accurate, and highly sensitive process to reliably detect minute traces of explosives on luggage, cargo, or traveling passengers has been demonstrated by scientists at the Department of Energy's Pacific Northwest National Laboratory. The vapor detection technology accurately detects and...

New NASA technology offers a look at distant planets that not only are the right size and traveling in the temperate habitable zone of their host star, but also show signs of potential life, such as atmospheric oxygen and liquid water.

Using small explosions produced by a mix of methane and oxygen, researchers at Harvard have designed a soft robot that can leap as much as a foot in the air. The ability to jump could one day prove critical in allowing the robots to avoid obstacles during search and rescue operations.

The Consumer Electronics Association (CEA) announced that this year's Consumer Electronics Show (CES) in Las Vegas had 25 percent more booths related to digital health and fitness technology compared to the previous year's event. Showcased products...

VTT Technical Research Centre of Finland has developed an automatic slipperiness detection system for cars that helps drivers avoid accidents in slippery road conditions. Thanks to the system, vehicles are warned in advance of a road’s actual slipperiness. If the road becomes slippery, other vehicles...

Engineers at MIT have now built an automated system that can rapidly produce 3-D, micron-resolution images of thousands of zebrafish larvae and precisely analyze their physical traits. The system offers a comprehensive view of how potential drugs affect vertebrates.

Wireless Telemetry System Captures Complex Flight of Dragonflies Duke University electrical engineers have developed a wirelessly powered telemetry system that is light and powerful enough to allow scientists to study the intricate neurological activity of dragonflies as they capture...
