TransPerformance The Performer The keypad and Liquid Crystal Display (LCD) on this guitar are the obvious tip-off to embedded electronics. A closer look reveals that the bridge and tailpiece are quite different, too. The guitar's six strings pass through a tuner assembly to the back of the guitar where six stepper motors simultaneously adjust each string's tension. The whole system is controlled by a microcontroller, but analog ICs interface to the stepper motors. The motors' speeds are adjustable with full-speed changes of one whole step per second. Touch-up accuracy is ± 2 cents. A cent is a logarithmic unit to measure musical intervals with 1,200 cents equal to one octave.

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 vehicle’s 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 that’s 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.
