Patent number: 9211751Abstract: A system is described for tracking a position of a receiver medium as it travels along a media path. A laser provides heat to the receiver medium in a localized area sufficient to permanently alter a physical property of the receiver medium thereby forming a reference mark. A sensor at a downstream position along the media path is adapted to sense the reference mark providing a sensed signal. The sensed signal is analyzed to determine a position of the receiver medium as the receiver medium passes through the second position along the media path by detecting a position of the reference mark.Type: GrantFiled: October 21, 2014Date of Patent: December 15, 2015Assignee: EASTMAN KODAK COMPANYInventors: Michael J. Piatt, Robert Edward Kauffman, James Douglas Wolf

Patent number: 9056736Abstract: A system is described for tracking a position of a receiver medium as it travels along a media path. A heat source provides heat to the receiver medium in a localized area sufficient to form a hole through the receiver medium thereby forming a reference mark. A light source illuminates a first side of the receiver medium, and a sensor located on a second side of the receiver medium senses light transmitted through the receiver medium thereby providing a sensed light level signal. The sensed light level signal is analyzed to determine a position of the receiver medium by detecting light transmitted through the hole through the receiver medium associated with the reference mark.Type: GrantFiled: July 15, 2013Date of Patent: June 16, 2015Assignee: EASTMAN KODAK COMPANYInventors: Michael Joseph Piatt, Robert Edward Kauffman, James Douglas Wolf

Patent number: 8960842Abstract: A system is described for tracking a position of a receiver medium as it travels along a media path. A heat source provides heat to the receiver medium in a localized area sufficient to permanently alter a fluorescent agent in the receiver medium, thereby forming a reference mark characterized by a reduced level of fluorescence. A stimulating light source illuminates the receiver medium at a downstream position along the media path, the stimulating light source having a spectrum adapted to stimulate the fluorescent agent to fluoresce thereby producing emitted light. A sensor is used to sense the emitted light from the receiver medium thereby providing a sensed light level signal. The sensed light level signal is analyzed to determine a position of the receiver medium by detecting the reduced level of fluorescence associated with the reference mark.Type: GrantFiled: July 15, 2013Date of Patent: February 24, 2015Assignee: Eastman Kodak CompanyInventors: Michael Joseph Piatt, Robert Edward Kauffman, James Douglas Wolf

Patent number: 6591617Abstract: A method is provided for delivering gaseous hydrogen to end users, the hydrogen being delivered in reusable storage tanks containing a plurality of carbon nanotubes. Liquid hydrogen is introduced into the tank, and the nanotubes absorb the hydrogen. The tanks are then warmed to normal temperatures and distributed to end users. The tanks are connected to the end-user system and are preferably installed within an air-tight enclosure, which may have an inert atmosphere. Alternatively, an inerting system monitors the air within the enclosure for free hydrogen and can release an inerting gas if free hydrogen is detected. The hydrogen is selectively released by heating the storage tank or by injecting a catalyst into the tank. When the usable hydrogen is depleted, the tank is retrieved from the end user for refurbishment and refilling.Type: GrantFiled: April 1, 2002Date of Patent: July 15, 2003Assignee: Lockheed Martin CorporationInventor: James Douglas Wolfe
