Patent number: 9679367Abstract: A system and method can mitigate or prevent contrast ratio issues due to bright light (e.g., light saturation) in a head up display (HUD). The head up display can include a waveguide combiner (or non-waveguide combiner) and a mitigator disposed to prevent or reduce bright light from being provided through the combiner. The bright light can be direct lunar light, direct solar light, or solar/lunar reflections. The mitigator dynamically selects and reduces bright background light which results in an increase of contrast ratio.Type: GrantFiled: April 24, 2014Date of Patent: June 13, 2017Assignee: Rockwell Collins, Inc.Inventors: Daniel S. Wald, Brandon E. Wilson, Eric P. Stratton, Conor D. Kelly

Patent number: 9004639Abstract: A method measures distances between two printed lines on a rotating image receiving member to identify fluid drop mass or fluid drop velocity changes in inkjet ejectors in an inkjet printing system. An initial distance between the two lines is measured at the start of the operational life of the system. During the operation of the printing system, the lines are reprinted and the distance between the two lines compared to the initial distance stored in association with the printheads that printed the lines. If the distance has changed by more than a predetermined amount, a printer parameter is adjusted.Type: GrantFiled: September 10, 2013Date of Patent: April 14, 2015Assignee: Xerox CorporationInventors: Conor D. Kelly, Mark R. Parker, Lisa M. Schmidt

An initial distance between the two lines is measured at the start of the operational life of the system. During the line of the printing system, the lines are reprinted and the distance between the two lines compared to the initial distance. If the distance has changed by more than a predetermined amount, a firing signal for the printheads that printed the lines is adjusted.Type: GrantFiled: April 29, 2011Date of Patent: November 12, 2013Assignee: Xerox CorporationInventors: Conor D.

Patent number: 8118391Abstract: A method of operating a printhead of an imaging device includes actuating a plurality of ink jets of the printhead to emit drops of ink onto an image receiving surface in accordance with a test pattern. The test pattern includes full pixel density areas and half pixel density areas that alternate in a process direction. Distances in a process direction between drops of the full pixel density areas and drops of the half pixel density areas in transition regions of the test pattern are then measured. The measured process direction distances are then correlated to a graininess level for the printhead.Type: GrantFiled: April 29, 2009Date of Patent: February 21, 2012Assignee: Xerox CorporationInventors: Trevor James Snyder, Brian Edward Williams, Susan J. Zoltner, Ernest I. Esplin, Conor D. Kelly

Patent number: 8088991Abstract: A method of operating a multi-junction photovoltaic cell with junctions connected in series includes operating each junction at a different, respective maximum power point. A photovoltaic circuit includes: at least one multi-junction photovoltaic cell, comprising at least first, second, and third terminals; a first junction of the photovoltaic cell positioned intermediate the first and second terminals; a second junction of the photovoltaic cell positioned intermediate the second and third terminals; and a device for independently setting current flow through the first junction and the second junction to allow for maximum power point operation of each junction, the device for setting current flow being connected to the second terminal.Type: GrantFiled: October 14, 2008Date of Patent: January 3, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Matthew Beasley, Conor D. Kelly, Wiatt E. Kettle
