Patents by Inventor Mark Muzzin

Mark Muzzin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Image scanning apparatus that scans both sides of an input sheet
    Patent number: 7511864
    Abstract: A document handler, such as used in a digital copier, includes an input tray and an output tray, connected by a paper path. Along the paper path are disposed two scan heads, one to record image data from each side of the sheet. The two scan heads are separated from each other along the paper path by a pitch length longer than a sheet to be scanned. The arrangement allows an image on each side of the sheet to be scanned at an exclusive time. For long sheets, a recirculation path, associated with the paper path, is used to allow the sheet to re-enter the paper path: in this way, one side of the sheet is scanned with one scan head, and then the other side is scanned with the other scan head.

  • Optical sensor for monitoring motion of a blank sheet
    Patent number: 7437120
    Abstract: An apparatus monitors the motion of sheet, such as in a digital printer. An optical sensor is capable of recording an image in a two-dimensional array of pixels, and has acuity to recognize a terrain of a small area on a sheet that is substantially blank to a human eye. The optical sensor views a portion of a sheet moving in a process direction through a path. A detection system compares at least two recorded terrain images from the sheet, thereby directly measuring velocity and direction of the sheet.
