Underground security system
The border-monitoring system, known as Helios, could watch the entire US-Mexico border continuously.
An underground surveillance system could watch the entire US-Mexico border continuously.
The border-monitoring system, known as Helios, consists of laser pulses transmitted through fiber-optic cables buried in the ground that respond to movements on the surface above. A detector at one or both ends of the cable analyzes these responses.
Helios is sensitive enough to detect a dog and can discriminate between people, horses and trucks. The system can avoid being triggered by small animals, and can also tell if people are running or walking, or digging, and in which direction, said researchers at The University of Arizona College of Engineering.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
