A structural battery prototype incorporates a cartilage-like material to make the batteries highly durable and easy to shape. The idea behind structural batteries is to store energy in structural components like the wing of a drone.

University of Illinois researchers are studying the physics of dynamic stall so that it can be used beneficially and reliably by aircraft. The problem has been studied at low speeds but at higher speeds, the process becomes significantly disorganized and difficult to understand.

It was a normal morning for design physicist Madison Martin at Lawrence Livermore National Laboratory (LLNL). At 7:45 a.m., she settled into her classified workstation with a cup of tea to check the results of a numerical calculation she ran overnight. If the calculations proved correct, the experiment she was designing on the National Ignition Facility (NIF) would deliver the data her colleagues needed to verify that a refurbished nuclear warhead would perform as expected.

Researchers from the U.S. Army and top universities discovered a new way to get more energy out of energetic materials containing aluminum, common in battlefield systems, by igniting aluminum micron powders coated with graphene oxide. This discovery coincides with the one of the Army's modernization priorities: Long Range Precision Fires. This research could lead to enhanced energetic performance of metal powders as propellant/explosive ingredients in the Army's munitions.

One of the most dangerous environments in the U.S. Navy is the deck of an aircraft carrier. Catapult systems that can remove limbs, furious engines, whipping propellers, and high winds create a hectic environment. The driving force behind all of these activities is helping a pilot land an aircraft on a short slab of pitching steel in the middle of the ocean. Although pilots are the stars of the show, they could not accomplish their missions without the support of flight deck crews, who are responsible for safely launching and recovering aircraft.

Well into its third decade of widespread deployment, VME adopted the new VXS gigabit serial interface, clearly representing the most significant leap in backplane data transfer rates throughout its entire history. Because VXS delivered such a dramatic improvement in embedded system performance, the use of gigabit serial technology was extended to create VPX. The OpenVPX initiative followed shortly thereafter, as risk-averse government agencies mandated the need for industry-wide standards. The hallmark of any successful standard is that it continues to evolve with technology, and none offers a better example than VME’s evolution to VXS and VPX.

In today’s world of high-speed A/D converters operating in the gigahertz range, real-time signal recording has become a challenging task that requires specialized hardware and intelligent application software. When designing a real-time recorder capable of streaming sustained data to disk at rates of up to 5 GB/sec and higher, the system developer has to consider the limitations presented by the recorder’s operating and file systems, the limitations of disk drive technology, the hardware interfaces, and the RAID controller technology.

FPGAs have become an increasingly important resource for software radio systems. Programmable logic technology now offers significant advantages for implementing software radio functions such as DDCs (Digital Downconverters). Over the past few years, the functions associated with DDCs have seen a shift from being delivered in ASICs (Application-Specific ICs) to operating as IP (Intellectual Property) in FPGAs.

To help define the meaning of “high-speed A/D” used in this handbook, we will be focusing primarily on A/D converters with sampling rates higher than 100 MHz. We will review sampling techniques, FPGA technology and we will present the latest Pentek high-speed A/D products and applications based on them.

SDR (Software-Defined Radio) has revolutionized electronic systems for a variety of applications including communications, data acquisition and signal processing.This handbook shows how DDCs (Digital Downconverters) and DUCs (Digital Upconverters), the fundamental building blocks of SDR, can replace legacy analog receiver and transmitter designs while offering significant benefits in performance, density and cost.
