An Operationally Based Vision Assessment Simulator for Domes

Applications include remote visualization, flight simulation, virtual environments, and planetariums. Ames Research Center, Moffett Field, California The work described here is part of the U.S. Air Force-sponsored Operational Based Vision Assessment (OBVA) program that has been tasked with developing a high-fidelity flight simulation laboratory to determine the relationship between human vision and performance in simulated operationally relevant tasks. The OBVA simulator was designed and built to provide the Air Force School of Aerospace Medicine (USAFSAM) with a scientific testing laboratory to study human vision and testing standards.

Self-Powered Intelligent Keyboard Could Provide Additional Security

By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered, non-mechanical, intelligent keyboard could provide a stronger layer of security for computer users. The self-powered device generates electricity when a user’s fingertips contact the multi-layer plastic materials that make up the device.

Ferroelectric Materials Could Revolutionize Data-Driven Devices

Electronic devices with unprecedented efficiency and data storage may someday run on ferroelectrics — remarkable materials that use built-in electric polarizations to read and write digital information, outperforming the magnets that are inside most popular data-driven technology. But ferroelectrics must first overcome a few key stumbling blocks, including a curious habit of "forgetting" stored data. Now, however, scientists at the U.S. Department of Energy's Brookhaven National Laboratory have discovered nanoscale asymmetries and charge preferences hidden within ferroelectrics that may explain their operational limits.

Scientists Demonstrate Data Teleportation for Secure Communications

Teleportation, a long-standing staple in the world of science fiction, has become a reality for scientists at the U.S. Army Research Laboratory in terms of battlefield data and image processing. Army Research Laboratory quantum information principal investigator Ronald Meyers and team member Keith Deacon recently demonstrated information teleportation using entangled photons.

New 3D Designs Double Solar Power

A team of MIT researchers is building cubes or towers that extend solar cells upward in three-dimensional configurations. The results from the structures they’ve tested show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.

Low-Power Quantum Computers

By 2017, quantum physics will help reduce the energy consumption of computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key issue. The next step will likely come from tunnel-FET, a technology that takes advantage of a phenomenon referred to as quantum tunneling. At the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, research is well underway.
