Recent developments in machine vision have demonstrated remarkable improvements in the ability of computers to properly identify objects in a viewing field. Most of these advances rely on color-texture analyses that require target objects to possess one or more highly distinctive, local features that can be...

Data compression leverages redundant data to free up storage capacity, boost computing speeds, and provide other perks. In current computer systems, accessing main memory is very expensive compared to actual computation. Because of this, using data compression in the memory helps improve...

The EHD pump uses electric fields to move a dielectric fluid coolant in a thermal loop to dissipate heat generated by electrical components with a low-power system. The pump has only a few key components and no moving parts, increasing the simplicity and robustness of the system. In...

Contamination of food with fragments of bone, metal, glass, or other foreign material is a major concern in the food industry. Current inspection technologies often miss very small fragments embedded in meat or other soft materials or lead to ambiguous results that require...

Researchers have developed a biosensor that attaches to a smartphone and uses bacteria to detect unsafe arsenic levels. The device generates easy-to-interpret patterns similar to volume-bars that display the level of contamination.

Currently, most U.S. medical offices and hospitals use the ELISA (enzyme-linked immunosorbent assay) test to determine whether or not a person has a viral infection. It’s a common test but ELISA’s sensitivity is relatively low, so clinicians need a fairly high number of antibodies in a person’s blood...
