The Adaptive Cruise Control (ACC) system automatically adjusts a vehicle's speed to maintain a constant headway between vehicles. A pre-set cruising speed is applied through the automatic adjustment of the throttle by downshifting and/or actuating "feather" braking. A radar headway sensor, hidden behind the grille, detects obstacles ahead and enables the vehicle to travel at a set speed or adapt to the speed of the vehicle in front. An on-board microcomputer processes the radar information and converts the electronic instructions into engine speed or brake pressure.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
