Self-Powered Sensors That Communicate Could Warn Of Bridge, Building Defects

Imagine a bridge or a dam that could sense a structural defect before it happens, diagnose what the problem will be and alert the authorities before something bad happens.

    Graphene Meets Heat Waves

    EPFL researchers have shed new light on the fundamental mechanisms of heat dissipation in graphene and other two-dimensional materials. They have shown that heat can propagate as a wave over very long distances. This is key information for engineering the electronics of tomorrow.

    Lack Of Effective Timing Signals Could Hamper 'Internet Of Things' Development

    Our fast-approaching future of driverless cars and “smart” electrical grids will depend on billions of linked devices making decisions and communicating with split-second precision to prevent highway collisions and power outages. But a new report released by the National Institute of Standards and Technology (NIST) warns that this future could be stalled by our lack of effective methods to marry computers and networks with timing systems.

    Venus Revealed In Radio Light

    From earthbound optical telescopes, the surface of Venus is shrouded beneath thick clouds made mostly of carbon dioxide. To penetrate this veil, probes like NASA’s Magellan spacecraft use radar to reveal remarkable features of this planet, like mountains, craters, and volcanoes.

    Overcoming Space Challenges And Reducing Costs With Small-Diameter Cable Technology

    Network service providers are deploying more fiber cables than ever to keep up with bandwidth demands. While that’s good news for those who want more bandwidth, it’s not so good for the technicians needing access to existing circuits or the ability to install new ones. In order to help central offices, headends, and other areas of a service network, and microcable patchcord was developed to slow the rate of cable pile-up and ease congestion in fiber-management systems.

A Cost Effective Approach To Simulation For Electronic Warfare Systems

Electronic Warfare (EW) comes in the forms of Electronic Attack (EA), Electronic Protection (EP), and Electronic Support (ES). The tightening of the DOD’s budget has made the already complex simulation of the spectral environments encountered by EW systems in field settings even more of a challenge.

The Third Wave Of CFD: Paradigm Shift Towards Simulation-Driven Designs

This white paper covers the history of simulation flow through the first two waves of CFD (computational fluid dynamics) technology, from the beginnings of commercially available CFD software through its entering of R&D departments. Lastly, it outlines the paradigm shift occurring in CFD technology as it has now become an essential element of the product design process as simulation-driven design is more prominent now than ever.

The Unique Requirements For Wireless Medical Devices

Medical device designers and manufacturers who don’t understand the unique requirements for ensuring success in a WLAN (wireless local area network) deployed solution run the risk of their device having adverse performance, potential regulatory recalls, the need for a product re-design, revenue loss, and competitive market positioning.  

The Basics Of Quadrifilar Helix Antennas

With the explosive growth of satellite-based services, the ability to receive or transmit a tight beam of circularly polarized radiation while minimizing unwanted radiation is imperative to maintaining good communication.  For such demanding applications, the axial-mode quadrifilar helical antenna provides a high performance and robust antenna platform both in space as well as on the ground.  Furthermore, for portable and handheld radio systems,  the quadrifilar helical antenna can be readily miniaturized, providing good quality circular polarization and near hemispherical coverage in the UHF and microwave bands.

    4 Electronic Design Requirements Of The System-Integrated Soldier

    Perhaps most famously portrayed in Robert Heinlein’s Starship Troopers (1959), the idea of the “future soldier” has been around for decades. As rehashed in countless science fiction films and video games, the stereotypical future soldier is equipped with a protective exoskeleton, enhanced sensory equipment, seamless communication systems, and advanced weaponry. While the concept once seemed implausible, there are many real-world projects under way focused on realizing those seemingly fictitious warfighter capabilities — by integrating a plethora of diverse electronic subsystems into a cohesively operational suit.

    7 Noteworthy Technologies From IMS2014

    At the 2014 IEEE MTT International Microwave Symposium earlier this month, I had the opportunity to speak with the event’s general chair, Dr. Larry Dunleavy, about the state of the RF and microwave design industry. While he acknowledged that it is a time of relative uncertainty — due in large part to constrained military budgets and conservative fiscal forecasts for 2014 — he also pointed out that there are plenty of emerging markets where RF and microwave technology is making a significant impact. With the Internet of Things (IoT) driving innovation in burgeoning markets like automotive and healthcare  and the development of 5G pushing wireless technology to further heights, there was good reason for nearly 600 companies to flock to the IMS2014 exhibition in Tampa, Fla.
