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.

This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
Hosted CAD or PDM systems is an emerging technology that offers many advantages over traditional on premise workstation CAD configurations and is making many companies rethink how to deliver future CAD software solutions.
