Curiosity Rover team members re-live the dramatic Aug. 6, 2012 landing and the mission's achievements to date in a recent event aired on NASA Television and the agency's website. In the year since inspiring millions of people worldwide with its one-of-a-kind landing in a crater on the Red Planet, Curiosity has achieved its primary scientific objective; finding evidence that ancient Mars could have sustained microbial life.
Today’s digital designs are evolving in a variety of ways, prompting new approaches to design, simulation, measurement and debug. One change is the use of more serial buses. Another is the use of system-on-a-chip (SOC) integrated circuits or advanced field-programmable gate arrays with SOC capability. Despite this evolution, there's still a role for classic parallel buses in many designs and the need to measure those buses.
Over the past decade, significant changes have been underway among users of electronic test and measurement instrumentation. For example, electronics companies’ R&D staffs have shrunk, and engineers report they are under pressure to do more with fewer resources than in the past. At the same time, there are fewer engineers dedicated to test with in-depth test and measurement training and background.
The space program in the mid-20th century accelerated the switch from analog to digital systems for high-speed data acquisition and monitoring. But systems recording today’s physical and electrical phenomena must meet a new set of data acquisition and logging challenges, making them unrecognizable to those early computer pioneers.
Afraid there may be peanuts or other allergens hiding in that cookie? Thanks to a cradle and app that turn your smartphone into a handheld biosensor, you may soon be able to run on-the-spot tests for food safety, environmental toxins, medical diagnostics and more.
Cable clutter is an eyesore and a tripping hazard in one. Researchers have developed a new kind of antenna hidden in tables that can wirelessly supply electronic devices with power. The power extends throughout the tabletop without the need for a large, impractical coil. The “tables” can transmit data, too.
What happens to a resonant wireless power transfer system in the presence of complex electromagnetic environments, such as metal plates? A team of researchers has explored the influences at play in this type of situation, and they describe how efficient wireless power transfer can be achieved in the presence of metal plates.
In an effort to thwart forgeries, researchers in Switzerland have proposed a new miniaturized authentication system. By combining moiré patterns and microlithography techniques, authorities can be easily recognize counterfeits with the naked eye and counterfeiters will find it impossible to reproduce items through currently existing printer or scanner technology.
Fluxes and turbulence caused by the interaction between the air and sea can significantly alter the path of electromagnetic waves in radar and communications systems. In effort to boost the U.S. navy’s communications performance at sea, researchers deployed Office of Naval Research unmanned aerial vehicles (UAVs) in an effort to determine the ocean and atmospheric weather variations that can change the angle that radar and radio waves bend.
A team of theoretical physicists at the U.S. Naval Research Laboratory and Boston College has identified cubic boron arsenide as a material with an extraordinarily high thermal conductivity and the potential to transfer heat more effectively from electronic devices than diamond, the best-known thermal conductor to date.
High speed oscilloscopes are vital tools in the development of high-speed digital networks. Teledyne LeCroy, a subsidiary of Teledyne Technologies Inc., this week demonstrated the world's first 100 GHz real-time oscilloscope by successfully acquiring and displaying live signals at 100 GHz bandwidth
According to scientists at Carnegie Mellon Univ. and Microsoft Research, the same 3-D printing process used to produce an object can simultaneously generate an internal, invisible tag. These internal tags, which the have been dubbed InfraStructs, can be read with an imaging system using terahertz radiation. As terahertz technology develops, these tags could have many applications.
Flexible electronics have a wide variety of possibilities, from bendable displays and batteries to medical implants that move with the body. Networks of spherical nanoparticles embedded in elastic materials may make the best stretchy conductors yet, engineering researchers at the Univ. of Michigan have discovered.
Researchers at Arizona State Univ. have successfully manufactured the world’s largest flexible color organic light emitting display prototype using advanced mixed oxide thin film transistors. Measuring 7.4 diagonal inches, the device was developed at ASU’s Flexible Display Center in conjunction with Army Research Labs scientists.
Antennas that are capable of transmitting radio waves turn components into intelligent objects. Researchers in Germany have now found a way to embed these antennas in fiber composites. As a result, the technology also works with carbon and glass fibers.
Scientists have developed an "intelligent knife" that can tell surgeons immediately whether the tissue they are cutting is cancerous or not. In the first study to test the invention in the operating theatre, the "iKnife" diagnosed tissue samples from 91 patients with 100% accuracy, instantly providing information that normally takes up to half an hour to reveal using laboratory tests.
A*STAR Institute of Microelectronics in Singapore and OPUS Microsystems Corp., a Taiwan-based company specializing in microelectromechanical systems (MEMS) scanning mirror devices, have signed an agreement to refine and develop a MEMS scanning mirror for smartphones applications. The goal is to shrink the MEMS micromirror to allow a pico-projector level of operation.
Researchers at the Univ. of Washington say one of the reasons face- and eye-recognition systems haven’t taken off is because the user’s experience often isn’t factored into the design. Their recent study, one of the first in the field to look at user preferences, found that speed, accuracy and choice of error messages were all important for the success of an eye-tracking system.
Using carpets of aligned carbon nanotubes, researchers from Rice University and Sandia National Laboratories have created a solid-state electronic device that is hardwired to detect polarized light across a broad swath of the visible and infrared spectrum.
With existing 3-D television displays, viewers must wear stereo glasses to get the effect of seeing images on the screen in three dimensions, while viewers without the glasses see a blurry image. Researchers at the University of California, Santa Cruz, have developed a prototype for 3-D+2-D television that allows viewers with stereo glasses to see 3-D images, while viewers without the glasses see a normal 2-D image.
Imagine this: There's no need to throw out your old cellphone, because it will self-destruct. That's the idea behind a project at the Univ. of Illinois at Urbana-Champaign, where researchers are investigating how to build electronics that vanish in water. A new video from the university explains their efforts.
In DARPA’s Virtual Robotics Challenge, 28 competing teams applied software of their own design to a simulated robot in an attempt to complete a series of tasks that are prerequisites for more complex activities. Just seven teams advanced to the next round, which was unveiled last week at Boston Dynamics: ATLAS, one of the most advanced humanoid robots ever built.
The Industrial Technology Research Institute (ITRI) has announced that it won three 2013 R&D 100 Award. ITRI has earned 16 awards for consecutive six years. ITRI's iAT technology, ButyFix and FluxMerge were awarded the three awards.
In an apple seed-sized pellet of glass, Univ. of Michigan engineering researchers have packed seven devices that together could potentially provide navigation in the absence of the satellite-based Global Positioning System (GPS.) Space-based GPS is far from fail-proof. It doesn't work indoors, near tall buildings or in heavy cloud cover; and it's relatively easy to jam, researchers say.
A low-cost system developed in Singapore, based on the principles of vibration and imaging, can turn a whiteboard, glass window or even a wooden tabletop into a responsive, touch-sensitive surface. According to its developers, retrofitting the system onto existing flat-panel TVs will transform them into new, touch-sensitive display screens.
