摘要： According to one aspect of the present invention an apparatus for multiple document detection comprises an ultrasonic transmitter (14) for transmitting an ultrasonic signal (16). An ultrasonic receiver (20) receives the ultrasonic signal (17), after it passes through the at least one of the multiple documents (18). A phase comparator (24) compares the transmitted ultrasonic signal (16) and the received ultrasonic signal (17), and an amplitude measurement circuit (26) compares the received ultrasonic signal (17) to a reference. A microprocessor (32) compares an information signal (28) from the phase comparator (24) and an information signal (30) from the amplitude measurement circuit (26) to a predetermined threshold to determine if multiple documents are present.

摘要： An apparatus (10) for detection of multiple documents (42) in a document transport system comprises a first transmitter (13) emitting a first signal at a first interval through a document feed path (40). A first sensor (14) detects the first signal from the first transmitter (13). A second transmitter (15) emits a second signal at a second interval through the document feed path (40). A second sensor (16) detects the second signal from the second transmitter (15).
