Abstract
A pattern discriminating apparatus with an interval integrating section for integrating detection signals from a detecting section for each of a number of intervals of a bill. A bill is supplied to the detecting section which detects, for example, a magnetism pattern of the bill. The detection signal from the detecting section is supplied to the interval integrating section as well as to a total integrating section. The total integrating section integrates the detection signals for one bill. The signals from the interval integrating section are temporarily stored in a memory section, are supplied to a smoothing section, and are smoothed thereby. The smoothed signal is supplied to normalizing section to be normalized based on the signal supplied from the total integrating section. The normalized signal and a signal output from a pattern memory section are supplied to a subtracting section for taking the difference between these two signals for each of the intervals. The difference signal thus obtained from the subtracting section is integrated in a difference integrating section for each interval and is then supplied to a discriminating section. Based on the signal from the difference integrating section, the discriminating section discriminates the authenticity, denomination and top or bottom surface of the bill.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
