Manufactured by Texas Instruments, DST (and variant) devices help secure millions of SpeedPass TM payment transponders and automobile ignition keys. Our analysis of the DST involved three phases: 1. Reverse engineering: Starting from a rough(More)
Accuracy levels of different scaling procedures for starting current measurements are addressed through statistical analysis of locked-rotor tests involving hundreds of medium- large induction machines. This is done so as to ascertain the confidence level of predicted full-voltage starting currents from reduced-voltage factory measurements, a necessity for(More)
