Research craft seeks to transform littoral operations.
The Office of Force Transformation’s Stiletto employs a novel m-hull design to give it high speed and smooth performance even in rough seas. The all-composite hull also weighs a fraction of its equivalent in steel, giving the craft a greater cargo or payload capability. Note the relative size of the two workers at dockside.
Reusable energy source allows soldiers to recharge batteries, run equipment in the field.
The collapsible metal air battery was developed to meet the needs of South Korea’s special operations forces. The device is used to charge radio batteries and as an emergency power source for electronics systems such as personal digital assistants and notebook computers.
Radio wave technology provides clarity without added interference.
An experimental radio technology may provide a more efficient means of alleviating bandwidth congestion in wireless communications. Operating at lower power than most radio devices, time-modulated ultrawideband technology fuses communications, radar and tracking capabilities into one piece of hardware that can deliver improved performance while remaining compatible with most legacy and commercial off-the-shelf systems.
No end is in sight to blazingly fast advances, say designers at major chip manufacturers.
One year after surviving the year 2000 problem, computer users may be blessed with huge leaps in processing speeds and capabilities. Researchers at semiconductor manufacturers are developing new generations of chips that, in just three years, will offer 15 times as many transistors and compute several times as fast as today’s models.
Developmental software itself ultimately may be the limiting factor in future semiconductor design.
Semiconductor designers are increasing their dependence on computer-aided design and testing to advance microcircuitry beyond the current state of the art. Demand for more and more complex chips has necessitated taking design out of the hands of engineers and into the realm of cyberspace.
Mini device proves powerful enough to run military electronics.
Georgia Institute of Technology (Georgia Tech) researchers (l-r) Dr. Iulica Zana, David Arnold and Dr. Jin-Woo Park work with a dime-size generator they developed that can produce enough power to run a cellular telephone. The generator will be incorporated into a microengine that will power military electronics.
Battle between imaging systems improves reliability, drives down costs, opens commercial opportunities.
Improved complementary metal-oxide semiconductor imaging technology allows entire video cameras to be integrated on a single chip, promising decreases in the price, complexity and size of cameras. Until recently, the image quality produced by these types of cameras has been less than ideal; however, the advent of active-pixel chips indicates that advancements in this arena not only are on the way, but also have arrived and are increasing practical applications of the technology.
Virtual National Laboratory races Moore’s Law, as minute circuitry requires increasingly careful design.
Extreme ultraviolet lithography, a technology being developed by a consortium of U.S. national laboratories and the semiconductor industry, is a strong contender to produce new generations of computer chips with features perhaps as small as 30 nanometers.
Scientists pursue miniaturization of chips by substituting chemical reactions for silicon.
A radical approach to semiconductor fabrication may soon lead to supercomputers the size of wristwatches. Scientists are developing logic gates based on molecular oxidation that could allow these building blocks of computers to be constructed of only a few molecules.
Once a specialized niche technology, silicon-on-insulator chips will soon appear in a wide variety of applications.
New production methods allow constructing semiconductors capable of operating at a fraction of the power of existing devices while delivering comparable or superior performance. These new technologies could lead to extremely efficient electronic devices, from handheld computers to tactical radios and missile warheads. The potential also exists for increased processor speeds in both military and civilian communications and computing applications.
Radiation-tolerant chips that run on a half volt could extend space vehicles’ operational lives.
Microprocessors capable of operating at extremely low power levels will soon fly in a variety of spacecraft. Radiation hardened in a novel process that allows them to be produced in existing facilities, the chips will play a role in future near-earth and deep-space missions. Moreover, the technology presents potential applications beyond aerospace circles, especially in battery-powered communications devices, sensors and portable electronics.
