A night vision system for a vehicle includes a pulsed light source for illuminating a region proximate the vehicle and a secondary trigger light source operating at a predetermined pulse timing and second wavelength. A stator core has stator slots in a bore in which the rotor is received. Bonding pads are separately arrayed on an upper part the unit semiconductor chip, and a second stress buffer layer formed on the first stress buffer layer and on the unit semiconductor chip, but not on an upper surface of each bonding pad. This invention also provides an automatic ball throwing device having the directing device of this invention and a method of converting a pitching machine into the same.
