A self-configurable radio receiver system was developed for relaying communication signals from multiple deep space assets. Most conventional radio receivers are hardwired to receive a specific type of signal and are incapable of receiving other types of signals without preconfiguration according...

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...

Magnetic materials can attract or repel each other based on their polar orientation — positive and negative ends attract each other, while two positives or two negatives repel. When an electromagnetic signal like a radio wave passes through such materials,...

NASA’s Glenn Research Center has devised an efficient new method of combining primary and secondary signals with minimal loss and noise. With its ability to reduce system noise, this novel signal combiner delivers the best opportunity to receive a desired signal not easily distinguished from background...

Researchers at NASA Johnson Space Center have developed the RFID Tag with Long Range and Wide Coverage Capabilities technology that allows a RFID tag to direct a RFID reader beam signal back in the direction of arrival. This technology requires no added power to provide telemetry for...

Today, underwater sensors cannot share data with those on land, as both use different wireless signals that only work in their respective mediums. Radio signals that travel through air die very rapidly in water. Acoustic signals, or sonar, sent by underwater devices...
