  • Patent number: 10894679
    Abstract: A device for reducing rotation of an article during singulation of a stack of articles is disclosed. The device may include a torsion element, a rotatable member configured to rotate about an elongated axis of the torsion element between a first position and a second position, and a revolving member coupled to the rotatable member. An outer surface of the revolving member contacts a drive belt in the first position and an article in the second position. The torsion element exerts torque on the rotatable member when it moves from the first position towards the second position. The torque causes the outer surface of the revolving member to apply a frictional force to the article, thereby minimizing rotation of the article. Systems and methods of singulating articles are also disclosed.

  • Patent number: 10366559
    Abstract: Systems and methods of the invention relate to reducing a number of jams that can occur in an automated teller machine with the employment of a moveable platen that increases a width of a channel for documents. A document analysis area can receive a document via a first transport path, wherein the document analysis area can include a channel in which the document travels to enable at least one scan component to capture an image of the document. The channel is created by one or more platen. The one or more platen can be movable to increase the width of the channel so as to allow documents to pass-through the document analysis area without causing a jam or error for the automated teller machine.
