Patent number: 11625968Abstract: Currency processing systems, coin processing machines, and methods of imaging coins are presented herein. A currency processing system is disclosed which includes a housing with a coin input area for receiving coins and coin receptacles for stowing processed coins. A disk-type coin processing unit is coupled to the coin input area and coin receptacles. The disk-type coin processing unit includes a rotatable disk for imparting motion to the coins, and a sorting head having a lower surface adjacent the rotatable disk. The lower surface forms various shaped regions for guiding the coins, under the motion imparted by the rotatable disk, to exit channels through which the coins are discharged to the coin receptacles. A linear array of sensors is mounted to the sorting head and/or the rotatable disk. The sensors examine each coin on the rotatable disk and output a signal indicative of coin image information for processing the coin.Type: GrantFiled: September 1, 2018Date of Patent: April 11, 2023Assignee: Cummins-Allison Corp.Inventors: Tomasz M. Jagielinski, Mathew Tomor, Araz Yacoubian, David J. Mecklenburg, Danny D. Yang

Patent number: 8781206Abstract: A document processing device includes a controller and a sensor arrangement. The sensor arrangement illuminates a surface of documents. The gradient index lens array collects light reflected from the documents and transmits at least a portion of the collected reflected light onto a photodetector array. The photodetector array generates one or more electrical signals in response to a gradient index lens transmitting light thereon. The controller derives data including image data from the one or more electrical signals. The image data is reproducible as a visually readable image of the surface of the documents. The visually readable image has a resolution such that alphanumeric characters can be extracted from the visually readable image in response to the document remaining within a depth of field of the gradient index lens array while being transported via the transport mechanism. The depth of field is at least about 0.03 inches.Type: GrantFiled: February 15, 2013Date of Patent: July 15, 2014Assignee: Cummins-Allison Corp.Inventors: Araz Yacoubian, Frank M. Csulits, Danny D.
