Making Sensor Networks And Radar Arrays More Energy-Efficient
Bethlehem, PA — Since when has censorship become a green activity?
Since Rick Blum and other experts in signal processing began seeking to make sensor networks and radar arrays more energy-efficient.
Sensor networks, says Blum, the Robert W. Wieseman Chair in electrical engineering, are playing a growing role in everyday life.
On a bridge, for example, sensors detect and process the signals caused by the stresses from passing vehicles and then transmit data to a central decision point. This helps engineers determine more quickly and accurately the likelihood that a bridge will fail.
Sensors also detect the presence of radioactive or other toxic waste in the environment. They can determine whether or not a cell is malignant. And they are used in military surveillance, air traffic control, home automation and other applications.
