Projection System and Nanomaterials Create New Driving Aids

Sunday, August 01 2010

Drivers with poor eyesight may soon have technology in automobiles that will help them see a road’s edges or possible hazards more clearly, and shop owners may be able to display colorful images onto their storefront windows because of a projection system innovation.

Channel Field Effect Transistors

Sunday, August 01 2010

Direct wafer bonding creates ideal channels made of extremely mismatched materials for field effect transistors.

Narrow bandgap semiconductors offer high carrier mobilities and low contact resistances, while wide bandgap semiconductors offer high breakdown voltages. A series of heterojunction transistors has been investigated and proved to be effective for improving both speed and power output. These devices include double heterostructure InP/InGaAs/InP bipolar transistors and composite-channel InAlAs/InGaAs/lnP/InAlAs high-electron-mobility transistors (HEMTs), which have taken full advantage of the matched lattice constant (or pseudomorphic growth).

Six Charge-Coupled Device (CCD) imaging sensors have been incorporated in NASA’s Solar Dynamics Observatory (SDO) spacecraft, the first of NASA’s Living With a Star (LWS) programs to launch. The LWS programs are designed to study and understand the causes of solar variability and their impact on Earth and near-Earth space. In order to study the Sun on small scales of space and time, and in many wavelengths simultaneously, the SDO has three scientific instruments on board: the Atmospheric Imaging Assembly (AIA), the EUV Variability Experiment (EVE), and the Helioseismic and Magnetic Imager (HMI).

UAV Airframes and Missions Drive Embedded Computing Choices

Sunday, August 01 2010

Every branch of the armed forces has a need for capabilities delivered from unmanned aerial vehicle/ unmanned aerial system (UAV/UAS) platforms. These unmanned vehicles have proved critical to improving situational awareness with surveillance and data collection, real-time communications, and even armament deployment. Key to the military’s technological approach to a modernized battlefield, new ideas for UAS use and deployment are spurring their expanded development as a priority among the Joint Forces. Enhanced systems are required to enable more sophisticated functionality, weaponization, and longer flight time at greater altitudes. Systems also need to be versatile to support a broader size range of UAS/UAV vehicles, from tanker-sized vehicles all the way down to micro-sized equipment. These diverse requirements are certainly a challenge to designers who must also ensure high reliability when operating in the rugged environment of a battlefield.
