Automated banking machine multiple sheet detector apparatus and method
First Claim
1. A method comprising:
- a) transmitting a sound wave through sheet media moving in a pathway of an automated banking machine, wherein the automated banking machine comprises a cash dispenser;
b) producing at least one receiver signal responsive to the sound wave, wherein at least a portion of the at least one receiver signal is produced responsive to the wave after having passed through the sheet media;
c) filtering the at least one receiver signal with respect to two reference signals which differ in phase by substantially 90 degrees;
d) through operation of at least one processor in the automated banking machine, responsive to (c) determining data representative of at least one change in phase of the sound wave caused by transmission through the sheet media; and
e) through operation of the at least one processor in the automated banking machine, determining responsive to the data determined in (d) whether the sheet media corresponds to a single sheet or at least two sheets in overlapped relation.

Abstract
A detector for a deposit accepting apparatus of an automated banking machine includes an ultrasonic transmitter driven by a driving signal operative to cause the ultrasonic transmitter to transmit an ultrasonic sound signal through a sheet pathway of the detector. The detector also includes an ultrasonic receiver operative to generate a receiver signal responsive to the ultrasonic sound signal. The detector further includes first and second correlation filters. The first and second correlation filters are operative to generate first and second outputs responsive to the receiver signal. At least one processor is operative responsive to the first and second outputs of the correlation filters to determine information associated with changes in phase of the ultrasonic sound signal and to distinguish between single and multiple sheets in the pathway responsive to the information associated with changes in phase.
