  • Coin discriminator
    Patent number: 5833042
    Abstract: A method of categorizing coins/tokens by energizing detect coils with a single pulse detecting the back EMF curve of the decaying pulse information, analyzing the unmodified back EMF curve to extract therefrom a number of variables and processing those variables to provide values proportional to the variables, and comparing the values of the coin/token to at least one of a number of reference values to determine into which of a number of predetermined categories the coin/token falls.
