Abstract: A method and apparatus for removing notes having gross defects from a currency processing machine prior to the notes entering the primary detection function of the machine. The invention involves the use of a gross defect detector module which detects notes having gross defects that could jam the machine if such defects were note detected and the notes were allowed to continue down the note path for processing. The invention works in conjunction with a conventional reject pocket located further downstream in the note path for the collection of notes identified as rejects during the subsequent main detection function.

Abstract: A method and apparatus for controlling note throughput in real time through a currency processing machine. The invention involves the use of asynchronous components, such as independently driven feeder, transport, and final disposition components, to vary individual note velocity and horizontal distance between notes as they are being processed. The adjustments are made in real time based on detected note quality characteristics and event characteristics of the inputting source of the notes.

Abstract: A diagnostic system for use in a bank note processing machine, and a method of use. The system includes a plurality of operating condition sensors positioned to monitor areas of interest within the machine. A CPU automatically reads the sensors to obtain an initial baseline reading against which operating data is compared. Decisions are made based upon this comparison.

Abstract: A system and method for obtaining a fill image of a bank note being processed. An array of magnetoresistive detectors is employed to obtain multiple line-scan sensings of a bank note as the note passes. A central processing unit obtains the plurality of sensings as magnetic pattern data which is subsequently stored in a database for later processing.

Abstract: A system and method for automatically detecting the presence of a perforation, tear, or a transparent window security feature in a bank note. The system includes an optical detection device, and an ultrasonic detection device, and a conveyance device for transporting the bank note along a defined path proximate the detection devices. Each detection device comprises a plurality of optical transmitters and corresponding optical receivers that bracket the note path. A computing device is also provided to determine from the output of the optical detection device the presence of an optical abnormality in the bank note; to determine from the output of the ultrasonic detection device the presence of an ultrasonic abnormality in the bank note; and to determine the presence of a perforation, tear, or transparent window feature based upon the results of the optical abnormality determination or the ultrasonic abnormality determination.
