Agile Aperture Antenna Tested on Aircraft to Maintain Satellite Connection

Two of Georgia Tech's software-defined, electronically reconfigurable Agile Aperture Antennas (A3) were demonstrated in an aircraft during flight tests. The low-power devices can change beam directions in a thousandth of a second. One device, looking up, maintained a satellite data connection as the aircraft changed headings, banked and rolled, while the other antenna looked down to track electromagnetic emitters on the ground.

New Algorithms Enable Self-Assembling, Printable Robots

In two new papers, MIT researchers demonstrate the promise of printable robotic components that, when heated, automatically fold into prescribed three-dimensional configurations.One paper describes a system that takes a digital specification of a 3-D shape — such as a computer-aided design, or CAD, file — and generates the 2-D patterns that would enable a piece of plastic to reproduce it through self-folding.The other paper explains how to build electrical components from self-folding laser-cut materials. The researchers present designs for resistors, inductors, and capacitors, as well as sensors and actuators — the electromechanical “muscles” that enable robots’ movements.“We have this big dream of the hardware compiler, where you can specify, ‘I want a robot that will play with my cat,’ or ‘I want a robot that will clean the floor,’ and from this high-level specification, you actually generate a working device,” said Daniela Rus, the Andrew and Erna Viterbi Professor of Electrical Engineering and Computer Science at MIT.SourceAlso: Learn about Self-Assembling, Flexible, Pre-Ceramic Composite Preforms.

Motion-Sensing Keyboard Lets Users Hover and Swipe

Microsoft engineers have developed a new type of augmented mechanical keyboard, sensing rich and expressive motion gestures performed both on and directly above the device. A low-resolution matrix of infrared (IR) proximity sensors is interspersed with the keys of a regular mechanical keyboard. This results in coarse, but high frame-rate motion data.

Cyberlearning Platforms Improve Design Collaboration

Two new "cyberlearning" platforms allow non-artists to create illustrations rivaling the work of expert designers. The platforms sidestep a key creative barrier by eliminating the need for drawing skills in developing new designs. "Non-experts are becoming more empowered and interested in means of creative self-expression," said Karthik Ramani, Purdue University's Donald W. Feddersen Professor of Mechanical Engineering. "More importantly, I think this is the beginning of a new field of computer-supported creativity where you are extending the human mind." The new platforms — called skWiki (pronounced squeaky) and Juxtapoze — may usher in a new era of digital-scribbling and creative collaboration. The platforms operate on servers and do not require users to install any software. The skWiki platform allows collaboration with multimedia, including text, sketches, photos and "vector images" important for computer-aided design and other applications.

Overcome Challenges of Your Highly Constrained PCB Designs

Layout constraints are an essential part of a PCB design. As the technology in modern electronic devices has become more complex (e.g. increasing speed, decreasing rise time and supply voltage values), signal integrity issues have become a primary concern. For many designs, this means a large percentage of nets require PCB layout constraints to meet signal integrity requirements. This brings two major challenges: creating a proper set of layout constraints for your design and applying those constraints during the PCB layout design process. This paper shows how to address the challenges of highly constrained designs.

Removing the Gap Between ECAD and MCAD Design

For ECAD and MCAD to collaborate in “real-time” a direct method of communication that facilitates a shared flow of data back and forth between design teams is required. This flow must support “what-if” scenarios of design baselines and change proposals along with the ability to counter-propose changes. Once design agreements are made, the flow must also dynamically update the design databases. This unique ECAD-MCAD (EDMD) collaborative environment has not been available until now. This desktop PCB design provides a real-time integrated ECAD-MCAD collaboration environment that enables Electrical and Mechanical design teams to work together throughout the entire design process.

Developing Smart and Affordable Intelligence, Surveillance and Reconnaissance Technologies: Five Trends to Watch

The demand for intelligence, surveillance and reconnaissance (ISR) technology and infrastructure is growing significantly. For example, in the 10 years from 2002 to 2011, U.S. Defense spending on ISR grew by a factor of six, compared with relatively flat defense spending overall [House Permanent Select Committee on Intelligence, 2012]. Similar patterns of spending can be seen around the globe. Simulation-based engineering has long played a role in advancing ISR technology development — from unmanned systems to antennas to systems and embedded software. The value proposition has long been proven.
