So how about an engine that sings? French technicians have programmed the controller for an Asiatech 10-cylinder, 750-hp Formula 1 engine (based on a Peugeot design), to run through various rpm/note ranges in the correct sequence to play a rousing sequence of musical notes. With five combustions per revolution at a frequency per second of 12/rpm [60/(5 x rpm)], the engine can produce revs for a particular note by multiplying the note's frequency by 12. For example, a 440 Hz A note needs 5,280 rpm and a C needs 3,139 rpm. For a demonstration of "When the Saints Come Marching In," go to http://astro.temple.edu/~kmr/Chauffe2.mp3.
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.
