Rad-Hard PM Optical Fibers for Space Gyro Application

              Optical fiber gyroscopes for space require a small form (for tight winding), small beat length (for high extinguishing ratio) and radiation hardness. Here we demonstrate an optical fiber specialized for space gyro applications, combining our expertise in optical waveguide design, optical material design and manufacture, optical measurement, and modeling of complex degradation and failure phenomena.

Fundamental Chemistry Could Help Extend Moore's Law

Over the years, computer chips have gotten smaller thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore's Law. But there's one component of the chip-making process in need of an overhaul if Moore's law is to continue: the chemical mixture called photoresist. Similar to film used in photography, photoresist, also just called resist, is used to lay down the patterns of ever-shrinking lines and features on a chip.

Prosthetic Arm Controlled by Imagining a Motion

Controlling a prosthetic arm by just imagining a motion may be possible through the work of Mexican scientists at the Centre for Research and Advanced Studies. First, it is necessary to know if there is a memory pattern in the amputee's brain in order to know how the arm moved. The pattern is then translated to instructions for the prosthesis.

Would You Use A Biometric System to Make Your Purchases?

Many consumers are making transactions today with contactless cards and mobile payments. Quixter, a biometric system developed in Sweden, allows consumers to make purchases quickly by reading vein patterns in their palm. The shopper holds his or her hand over the device after entering the last four digits of a phone number.

Scott Jensen, Aerospace Technologist (AST) Electronics Engineer, Stennis Space Center, Mississippi

Scott Jensen and his team developed the Valve Health Monitoring System (VHMS), a technology designed for detecting deterioration in the mechanical integrity of high-geared ball valves and linearly actuated valves. Beyond valve monitoring, the technology has also been effective at performing real-time verification for structural integrity of hydrogen barge dock facilities.
