The CM01H900 common-mode choke coil from Taiyo Yuden (U.S.A.) Inc. (Schaumburg, IL) measures 1.2(L) × 1.0(W) × 0.9(H) mm, reportedly the industry’s smallest. The coil’s common-mode impedance is 65 ohms at 100 MHz.

Looking at ways to encode an image as a file, one byte in the file contributes information to one pixel (PPM files) or a small group of pixels (GIF, JPEG). In other image technologies such as wavelets, certain bytes contribute much more information than others. Lossy...

This emissions control system effectively reduces up to 100% of hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) from fossil fuel combustion engines. It is suitable for gasoline, natural gas, propane, syngas, and diesel engines. The Emission Reduction System technology is...

A company’s current product is applied in granular or prill form, and a coating acts to inhibit the release of the product within. The company is looking for a method to modify the release of the organic compound. The compound becomes active when it comes into contact with...

A company supplies a variety of chemicals, including inverse emulsions that consist of a very-high-molecular weight, water-soluble polymer dispersed in a continuous oil phase. The typical ratio of the key components is approximately 1:1:1...

Researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the California Institute of Technology have developed a whispering gallery microcavity based on plasmons - electromagnetic waves that race across the surfaces of metals. This plasmonic whispering gallery microcavity consists of a silica...

Over a million people attended the inauguration of President Barack Obama in Washington last week. With extremely tight security restricting access, photographer David Bergman found an ingenious way to photograph the event, with the help of imaging technology used on the Mars Rover.
