What do an intelligent user interface, an antitheft suitcase, and a water leak monitor have in common? Motorola's MC33794 E-Field Imaging IC.

That's right: one part, endless possibilities. But don't just take our word for it; check out the various designs that placed in the 2003 Motorola E-Field Sensor Contest to get a better sense of the MC33794's applicability.

Congratulations to all of the winners, especially Bruce Pride, whose Smart-E-Touch—which is an adaptable touchscreen-based user interface—took the Grand Prize. All it took was a pair of MC33794 e-field sensors, the Motorola MC68HC908QY4T, and a little innovation on Bruce's part.
