An apparatus to measure the coefficient of kinetic friction (mu k) between the shoe sole and the underfoot surface was constructed, and a method including criteria to evaluate the risk of slipping during walking was developed. The apparatus is a prototype stationary step simulator capable of simulating the movements of a human foot and the forces applied to(More)
We propose a new method for the integral non-linearity (INL) and differential nonlinearity (DNL) testing of D/A - A/D converter pairs employing the recently developed stimulus identification method. This allows both converters to be measured independently but simultaneously without significant fault masking problems. Simulations show that the INL and DNL(More)
