Optical hardware has been developed to measure the depth of defects in the Space Shuttle Orbiter’s windows. In this hardware, a mirror is translated such that its position corresponds to the defect’s depth, so the depth measurement problem is transferred to a mirror-position measurement problem. This is...

This oscillator uses a single-emitter 0.3-μm InP heterojunction bipolar transistor (HBT) device with maximum frequency of oscillation (fmax) greater than 500 GHz. Due to high conductor and substrate losses at submillimeter-wave frequencies, a primary challenge is to efficiently use the...

The silicon substrate carrier was created so that a large-area array (in this case 62,000+ elements of a microshutter array) and a variety of discrete passive and active devices could be mounted on a single board, similar to a printed circuit board. However, the density and...

Charge coupled device (CCD) imaging sensors e2v Chelmsford, UK 44 (0)1245 493493 www.e2v.com e2v CCD imaging sensors were launched recently on the Space Shuttle Atlantis as part of a mission to upgrade and repair the Hubble Space Telescope. The imaging sensors equip the Wide Field Camera 3...

TRW has been making parts for the automotive industry for many years, but when Ford Automotive considered giving them the contract to manufacture the rear toe-links for their Navigator and Expedition SUVs, their traditional lathes were considered inadequate for the task. The solution was to...

A team led by Professor Yosi Shacham-Diamand, vice-dean of Tel Aviv University's Faculty of Engineering, has developed a nano-sized laboratory, complete with a microscopic workbench, to measure water quality in real time. This lab-on-a-chip is a breakthrough in the effort to keep water safe from pollution. "We've developed a platform...

Physicists, engineers, and technicians from the University of Delaware's Bartol Research Institute are part of an international team working to build the world's largest neutrino telescope in the Antarctic ice. Neutrinos have no electrical charge and can travel millions of miles through space. Dubbed "IceCube," the telescope will...
