Abstract
Abstract 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.

A currency counting and evaluation device for receiving a stack of currency bills, rapidly counting and evaluating all the bills in the stack, and then re-stacking the bills, said device comprising a feed mechanism for receiving a stack of currency bills and feeding said bills, one at a time, to a bill transport mechanism; said bill transport mechanism transporting bills from said feed mechanism to a stacking station, at a rate in excess of about 800 bills per minute; an optical scanning head located between said feed mechanism and said stacking station for scanning a preselected segment of a central portion of each bill transported between said stations by said transport mechanism, said scanning head including at least one light source for illuminating a strip of said preselected segment of a bill, and at least one detector for receiving light from the illuminated strip on the bill and producing an output signal representing variations in the intensity of the received light; means for sampling said output signal at preselected intervals as a bill is moved across said scanning head, each of said output signal samples being proportional to the intensity of the light received from a different strip of said preselected segment of a bill; a memory for storing characteristic signal samples produced by scanning said preselected segments of bills of different denominations with said scanning head and sampling said output signal at said preselected intervals, each of said stored signal samples being proportional to the intensity of the light received from a different strip of said preselected segment of a bill; and signal processing means for receiving said signal samples and (1) determining the denomination of each scanned bill by comparing said stored signal samples with said output signal samples produced by the scanning of each bill with said scanning head, (2) counting the number of scanned bills of each denomination, said signal processing means being capable of determining the denomination of each scanned bill by comparing stored signal samples and output signal samples associated only with scanning said central portion of each bill, and (3) accumulating the cumulative value of the scanned bills of each denomination.

Claim 84
Dependent Claim
123 words
A currency evaluation device for receiving a stack of currency bills and rapidly evaluating all the bills in the stack, said device comprising: an input receptacle for receiving a stack of bills to be evaluated; a single output receptacle for receiving said bills after said bills have been evaluated; a transport mechanism for transporting said bills, one at a time, from said input receptacle to said output receptacle along a transport path; a discriminating unit for evaluating said bills, said discriminating unit including a detector positioned along said transport path between said input receptacle and said output receptacle, said discriminating unit counting and determining the denomination of said bills; and means for flagging a bill meeting or failing to meet a certain criteria.
Claim 85
Dependent Claim

A currency evaluation device for receiving a stack of currency bills and rapidly evaluating all the bills in the stack, said device comprising: an input receptacle for receiving a stack of bills to be evaluated; a single output receptacle for receiving said bills after said bills have been evaluated; a transport mechanism for transporting said bills, one at a time, from said input receptacle to said output receptacle along a transport path; a discriminating unit for evaluating said bills, said discriminating unit including a detector positioned along said transport path between said input receptacle and said output receptacle, said discriminating unit counting and determining the denomination of said bills; and means for flagging a bill meeting or failing to meet a certain criteria.
Claim 86
Dependent Claim
41 words
The currency evaluation device of claim 76 wherein said means for flagging a bill causes said transport mechanism to halt with said bill meeting or failing to meet said certain criteria being positioned at an identifiable location in said output receptacle.
Claim 87
Dependent Claim
50 words
The currency evaluation device of claim 77 wherein said certain criteria is said discriminating unit determining the denomination of said bill and wherein said means for flagging causes said transport mechanism to halt when said bill fails to meet said criteria of having its denomination determined by said discriminating unit.
Claim 88
Dependent Claim
131 words
