This General Motors engineer helps run a pilot program to retrain displaced engineers in advanced propulsion.

Designers are turning to MEMS sensors as a way of devising superresponsive operator controls.

Hydraulic fan drives cut fuel costs, increase power, and reduce emissions.

Many conventional rotary and indexing applications are solved with standard ball or roller bearings, especially in the smaller size ranges of up to 200-mm diameter.

Advanced video-imaging sensors and driver-assistance systems may make auto accidents increasingly rare.
