摘要:
A document handling apparatus having a document transport path for moving a document therethrough. A detector proximate the transport detects a multifeed indication in the transport path or a misfeed indication in the transport path. A processing system processes the indications and issues a termination signal if a multifeed or a misfeed, or both, is determined.
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.

A document handling apparatus having a document transport path for moving a document therethrough. A single detector proximate the transport detects a misfeed indication in the transport path. A processing system processes the indication and issues a termination signal if a misfeed is determined.
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 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 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.
