Making 'Smart' Safe -- When Every Millisecond Matters

Click image to enlarge

"We're enriching the toolbox of CPS architects and engineers and making it possible for them to rigorously develop networked cyber physical systems with hard-real-time performance guarantees for applications in which every millisecond matters," says Dr. Liang Cheng, an associate professor of computer science and engineering at Lehigh University's P.C Rossin College of Engineering and Applied Science. Cheng, who is a member of the Leadership Council of Lehigh's new Institute for Cyber Physical Infrastructure and Energy (I-CPIE), was recently awarded nearly $500,000 in funding from the National Science Foundation's Cyber-Physical Systems (CPS) program.

A driver behind the wheel of a luxury sedan spills a cup of hot coffee and, in a moment of distraction, suddenly faces a life-shattering crash. But in a split second--cue the dramatic pause--the vehicle's automatic breaking or crash avoidance technology engages the car's brakes. A time-critical
