Valveless Hydraulics Cuts Fuel Consumption in Construction Vehicles
Purdue University professor Monika Ivantysynova and doctoral student Naseem Daher discuss research related to new hydraulic steering technology, while graduate student Michael Sprengel looks over the electronic controls of a front loader. Researchers led by Ivantysynova, a fluid systems professor at Purdue's School of Mechanical Engineering, have shown how to reduce fuel consumption while improving the efficiency of hydraulic steering systems in heavy construction equipment.

An interesting idea. There would be less plumbing; fewer hoses to dry out, seals to fail and losses from the hoses flexing during actuation. I wonder if there is a weight benefit from the reduced plumbing too.
Kaspersky Labs indicated at its February meeting that cyber attacks are far more sophisticated than previous thought. It turns out even air-gapping (disconnecting computers from the Internet to protect against cyber intrusion) isnít a foolproof way to avoid getting hacked. And Kaspersky implied the NSA is the smartest attacker.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
