摘要： An improved method and apparatus for discriminating between currency bills of different denominations uses an optical sensing and correlation technique based on the sensing of bill reflectance characteristics obtained by illuminating and scanning a bill along its narrow dimension. A series of detected reflectance signals are obtained by sampling and digitally processing, under microprocessor control, the reflected light at a plurality of predefined sample points as a currency bill is moved across an illuminated strip with its narrow dimension parallel to the direction of transport of the bill. The sample data is subjected to digital processing, including a normalizing process, whereby the reflectance data represents a characteristic pattern that is unique for a given bill denomination and incorporates sufficient distinguishing features between characteristic patterns for discriminating between different currency denominations. A plurality of master characteristic patterns are generated and stored using original bills for each denomination of currency to be detected. The pattern generated by scanning a bill under test and processing the data samples is compared with each of the prestored master patterns to generate, for each comparison, a correlation number representing the extent of similarity between corresponding ones of the plurality of data samples for the compared patterns. Denomination identification is based on designating the scanned bill as belonging to the denomination corresponding to the stored master pattern for which the correlation number resulting from pattern comparison is determined to be the highest, subject to a bi-level threshold of correlation.

摘要： A U.S. currency evaluation device for receiving a stack of U.S. currency bills and rapidly evaluating all the bills in the stack. According to one embodiment the device comprises an input receptacle positioned to receive a stack of bills to be evaluated and at least one output receptacle positioned to receive bills after evaluation. A transport mechanism transports the bills, one at a time, from the input receptacle to the at least one output receptacle. The device also comprises a denomination discriminating unit adapted to denominate bills of a plurality of U.S. denominations. According to some embodiments, the device is adapted to deliver any bill that has been denominated to one and only one of the at least one output receptacle. According to some embodiments, the device has a single output receptacle.
