Abstract

A scale under microprocessor control weighs each batch of currency. The weight measurement is compared against predetermined stored weight values to determine if the currency being weighed is strap currency or unstrapped currency and to determine the range of the currency count. Dependent upon the result of these comparisons, the proper routine is selected during which the last currency measurement is compared against the measurement criteria of the selected routine to either confirm the accuracy of the count or indicate an error. An average strap value is created from a table of stored values for at least one of the strap quantities and is updated each time a strap of that quantity is weighed. The averaging technique employed creates an average from the weights of the last ten straps of that quantity measured, and which are stored in the table. The averaging is performed after the table is updated. From this average, the value for each strap quantity and each single bill is recalculated and stored in memory in readiness for subsequent counting operations and/or verificiations. A table of stored values is created for each bill denomination.

  1. 1. A method for verifying the accuracy of the count of a previously wrapped bundle of sheets through the use of a computer having a memory and an electronic scale comprising the steps of:storing predetermined valid upper and lower weight limits in the memory;weighing said bundle on the scale;comparing the bundle weight with the valid upper and lower limits for said bundle stored in the memory;providing an indication when the bundle weight is outside of said valid limits;storing the bundle weights for a predetermined number of bundles of the desired bundle count in the memory;disposing of the oldest weight stored when the stored bundle weights reach the maximum number of bundle weights stored in memory;calculating an average bundle weight from the bundle weights stored in memory;adding a first factor stored in said memory to the average bundle weight to develop a high valid weight limit;subtracting a second factor stored in said memory from the average bundle weight to develop a low valid weight; andstoring the low and high valid weights for use in verifying the next strapped bundle of the denomination and quantity.
  2. 13. A method for creating a table of stored values in a computer coupled to an electronic scale, and having a memory for verifying the number of sheets contained within a strapped bundle having a predetermined number of sheets comprising the steps of:weighing the strapped bundle on said scale;inserting the weight value into each location in memory within a table having a predetermined number of storage locations;multiplying the weight of the strapped bundle by a number equal to the number of storage locations in said table to obtain a total weight;subtracting the value in the first storage position in the table from the product of said multiplication;moving each of the values in the remaining positions in said table up by one location towards said first location;inserting the newly obtained weight into the last storage location in said table, and adding the newly obtained weight to the total weight;adding a factor to the total weight to compensate for the strap weight;dividing the total weight by a number equal to the number of positions in said table to obtain a calculated average weight;adding a factor to the calculated average weight to form a valid high weight and storing said valid high weight in said memory;subtracting a factor from the calculated average weight to form a valid low weight and placing said valid low weight in said memory to provide a comparison table to use in verifying the weight of the next strapped bundle of purportedly the same count.
