Haydon Kerk has recent designed a new type of linear actuator to control the power to a cement mixer aboard a piece of heavy construction equipment. The actuator is completely sealed to withstand dirt, debris, heat, and moisture.
For 25 years, scientists have employed a network of land-based video cameras called Argus stations to monitor coastal surf zones in an effort to learn about the ever-changing dynamics of the surf zone. Now scientists at Oregon State University are working to incorporate a new resource into the Argus system—beach cameras.
The additive manufacturing industry will greatly benefit from a new ASTM International standard that will allow computer-aided design programs, scanners, and 3D graphical editors to communicate with 3D printers and additive manufacturing equipment. The standard will answer the growing need within the industry for a standard interchange file format that can work with features such as color, texture, material, substructure, and other properties of a fabricated target object.
EOS, a manufacturer of laser sintering systems, in collaboration with EADS Innovation Works (IW), has started work on a study to understand the potential of the direct metal laser sintering (DMLS) process to generate savings in the use of energy and raw materials.
Researchers are working on egg-sized robots that are designed to dive into nuclear reactors and swim through underground pipes, checking for sign of corrosion. The underwater patrollers, equipped with cameras, are able to withstand a nuclear reactor's extreme, radioactive environment, and can transmit images in real-time.
Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced the observation of a new particle, the neutral Xi-sub-b, which contains a strange quark, an up quark, and a bottom quark (s-u-b).
An augmented reality solution developed by engineers in Germany is designed to allow technicians to record malfunctioning machines with a camera fixed to the back of a laptop monitor attached to a swivel arm. The system lets technicians perform repairs with the help of visual aids, and without having to interrupt their work by talking on the telephone.
The drilling team from the Integrated Ocean Drilling Program (IODP) have pushed Hole 1256D, a deep scientific borehole, more than 1,500 m below the seafloor and into the Pacific Ocean's igneous crust. They are now encountering metamorphic rocks that is sometimes even tougher than the most resilient of hard formation drilling and coring bits.
NASA, NIH, NSF and USDA are combining forces to fast-track the development and use of co-robots in the U.S. that work cooperatively with people. A solicitation for proposals for the new National Robotics Initiative (NRI) was recently released along with the establishment of the Advanced Manufacturing Partnership. Investments in NRI may reach $50 million in the first year.
MIT researchers show how to make e-beam lithography, commonly used to prototype computer chips, more practical as a mass-production technique.
Battelle has granted an exclusive license for a technology that will help clothing shoppers find better fitting clothes easily and quickly, as well as assess their overall fitness.
Scientists of the MINOS experiment at the Fermi National Accelerator Laboratory announced the results from a search for a rare phenomenon, the transformation of muon neutrinos into electron neutrinos. The result is consistent with and significantly constrains a measurement reported by the Japanese T2K experiment, which announced an indication of this type of transformation.
When finished, the 4.2-meter mirror being crafted by the Univ. of Arizona’s College of Optical Sciences for the Advanced Technology Solar Telescope in Hawaii will be the largest telescope mirror ever pointed at the sun. Complicating the task of polishing this mirror is the shape: the telescope’s design calls for a complex off-axis paraboloid surface.
Hair breaks. It singes. It falls out. It might not be the strongest feature of living human bodies, but hair is one of the best-preserved tissues of dead ones, providing a record of diet, age, metabolism, and sometimes, even the cause of death. With intense beams of x-rays at Brookhaven's National Synchrotron Light Source (NSLS), a team of researchers is using hair samples collected from the decomposed bodies of two 15th-century Italian royals to determine how they really died.
Students in California are taking what would normally be annoyance and making it an asset. They are working to implement a system that uses heat that collects in a home’s attic to warm a thermal closet that would dry clothes. Supplemented by power from a roof-mounted solar cell, the closet could cut electricity bills up to 16%.
MIT mechanical engineers are working to develop a new intelligent transportation system (ITS) algorithm that takes into account models of human driving behavior to warn drivers of potential collisions, and ultimately takes control of the vehicle to prevent a crash.
Airport security workers this year will employ an array of pre-boarding detection measures to scan for deadly materials smuggled into the luggage of the world’s 625 million passengers expected to travel this year. None, however, yet uses what researchers at the Univ. of Florida believe is the world's first explosive detection system that utilizes ultraviolet light to zero in on specks of dangerous explosives found on these items.
Prototyping systems can move a design concept from CAD data to a 3D model rapidly and accurately when using the appropriate tool for the task.
One of China’s biggest, state-owned rare earths miners and producers has been given a monopoly over rare earth mining, processing, and trading in the northern part of the country. The move is an effort by the country’s government to bring the rare earths industry, which provides 97% of global supply, under tighter control.
Neutron analysis of the atomic dynamics behind thermal conductivity is helping scientists at the Department of Energy's Oak Ridge National Laboratory gain a deeper understanding of how thermoelectric materials work. The analysis could spur the development of a broader range of products with the capability to transform heat to electricity.
In revisiting the 255 year-old Leidenfrost effect, which describes how a liquid produces an insulating vapor layer when contacting a solid hotter than its boiling point, researchers at the University of Melbourne and the King Abdullah University of Science and Technology in Saudi Arabia have found a new way to reduce drag on large ships.
Researchers at Aalto Univ. in Finland have found a way to cut the amount of fuel consumed by non-road mobile machinery by half. This new technology captures energy, which up to now has been lost by the machinery when working, and uses it instead of fuel. The fuel consumption of construction and mining machines, agricultural machines, and material handling machines is reduced significantly.
Last weekend, the Martin Jetpack successfully lifted off, pilot attached, over the New Zealand landscape. The test showcased the machine’s ability to quickly achieve 5,000 feet in altitude and deploy the world’s first ballistic jetpack parachute before returning to earth. The Martin Aircraft Company’s goal is to provide jetpack flight for less than $100,000.
Imagine a robot able to retrieve a pile of laundry from the back of a cluttered closet, deliver it to a washing machine, start the cycle, and then zip off to the kitchen to start preparing dinner. This may have been a domestic dream a half-century ago, when the fields of robotics and artificial intelligence first captured public imagination. However, it quickly became clear that even "simple" human actions are extremely difficult to replicate in robots. Now, MIT computer scientists are tackling the problem with a hierarchical, progressive algorithm that has the potential to greatly reduce the computational cost associated with performing complex actions.
After lying dormant for hundreds of millions of years, shale gas was tapped for the first time in a natural gas well in 1821. Since then, oil has taken the spotlight, but now shale gas is looked to as the energy resource of the present and future. The National Energy Technology Laboratory, which helped pioneer hydraulic fracturing and horizontal drilling, tracks some of the technological developments in shale gas extraction.
