摘要:
An apparatus for classifying documents (5) based on sound includes a document transport (30) for transporting a document; an audio transducer (20) for detecting a sonic profile produced by the document as it is transported; and a controller for determining document characteristics based on the sonic profile.
摘要:
A method to identify and classify a document (5) by weight or thickness based on the sound the document makes while moving through a document transport (30). Using an audio transducer (20), the sound of the document is captured and compared to previously saved and stored characteristics of various weighted documents and then classified when matched to a specific set of characteristics.
摘要:
A method and apparatus for correcting for a phase shift between a transmitter and receiver comprising the steps of: a) transmitting a signal from a transmitter (14); b) receiving the transmitted signal (16) at a receiver (20); c) comparing the received signal (17) to a reference signal; d) if a difference between the reference signal and the received signal (17) is greater than a predetermined value go to step e), if not go to step g); e) adjusting a frequency of the transmitted signal (16); f) go to step a); and g) calibration complete.
摘要:
A method for feeding sheets through a sheet transport path. Ultrasonic energy is directed toward a sheet in the transport path while an audio receiver detects audio data generated by the ultrasonic source and the mechanisms that transport the sheet. The audio data is processed to determine whether a multifeed or a misfeed condition exists in the transport path.
摘要:
A document scanner (10) includes an input tray (20) for holding documents (11); an input image capture device (30) for capturing images of documents in the input tray; an image processor for determining characteristics of documents; and the documents are processed based on the characteristics.
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).
摘要:
An apparatus for detection of multiple documents (10) in a document transport system comprises a transmitter (15), located on a first side of a document feed path (40), and emits a signal through the document feed path. A reflector (52), located on a second side of said document feed path, reflects the signal through the document feed path. A first sensor detects the signal from the transmitter. A second sensor detects the signal from the transmitter.
摘要:
A method for preventing damage to a document by a document transport apparatus provides a member for receiving the document as a stack of sheets to be serial fed to a feeding station. At least two spaced-apart microphones are disposed at the feeding station and responsive to audio to produce signals representing audio energy received by each microphone respectively. The energy received from each microphone is compared to determine if it is ambient noise or if it indicates that two attached sheets are being fed or a single sheet is being damaged. The document transport apparatus is shut off to prevent damage to documents when it has been determined that two attached sheets are being fed or that a single sheet is being damaged.
摘要:
A document scanner (10) includes an input tray (30) for holding documents (20) prior to imaging; an output tray (150) for holding documents after the documents exit the scanner; an output image capture device (140) for capturing images of the output tray; an image processor for determining characteristics of the output tray or characteristic of the documents after the documents exit the scanner; and scanner functions are modified based on the output tray characteristics or the document characteristics.
