  • Article checkout system with price parameter override capacity
    Patent number: 5424521
    Abstract: A system for processing articles selected for purchase and bearing an identification code, comprises a code reader for generating output signals indicative of the article identification codes, a first storage unit for storage, for each of the articles, of a signal indicative of a price for the article correlated with the article identification, a second storage unit selectively operable for temporary storage of a signal indicative of a price for an article selected for purchase correlated with the article identification, and a control unit operable on receipt of the code reader output signals for fetching the price-indicative signal from the first storage unit, selectively operable on failure of the price fetching from the first storage unit for accepting operator input of a price-indicative signal for the article and storing the operator input signal in the second storage unit, and for fetching the price-indicative signal for the article from the second storage unit until such time as a price-indicative sign

  • Article checkout system with security parameter override capacity
    Patent number: 5340970
    Abstract: A system of the so-called "operator-unassisted" type, for processing articles selected for purchase and bearing an identification code, includes a code reader generating output signals indicative of the article identification codes, a sensor generating output signals indicative of measurable characteristics of the articles, a memory for storage, for each of the articles, of a signal indicative of the measurable characteristic thereof correlated with the article identification code, an article rejector for rejecting the selection of an article for purchase on failure of correspondence of the sensor output signal and the corresponding stored measurable characteristic signal and a control unit operable selectively on such rejection of the article purchase selection for substituting the output signal generated by the sensor for the stored measurable characteristic signal. The control unit effectively introduces an "override capacity" to heretofore known systems.
