On August nights, stars fall out of the sky in meteor showers while young people are gunned down at random on the playground, on the stoop or on U.S. 26 in Portland, Ore., where a 29-year-old man was shot on Aug. 11 after merging into another driver's...
A team at the Los Alamos National Laboratory is working with the University of California at San Diego to design and power small sensors to place on bridges - or on any piece of infrastructure for that matter - that would measure structural problems like strain, deflection, cracks, corrosion or the loosening...
The idea is to partner with state departments of transportation or highway patrols to use the technology, Farrar says, because they could control the feedback, determining how often they want a reading of the sensors - once a minute, once a month, once a year. The sensors could eventually replace the...
The chief problem with the sensor technology is how to find an inexpensive way of transmitting the sensors' data to computers. Sensors currently rely on batteries that often need to be replaced, and they require a fair amount of bulky hardware. "Right now, it wouldn't be a cost-effective...
Farrar agrees and says the Los Alamos lab has been testing sensors on bridges for the last 10 years, but that the technology is not yet ready for implementation. His team is about a year and a half into a four-year project to test and develop this technology, and...
