Patents by Inventor Marti Rius Rossell

Marti Rius Rossell 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).

  • Patent number: 8902426
    Abstract: A densitometer includes a plurality of light-emitting diodes (LEDs) and at least one sensor. The LEDs are activated one at a time in a sequential, repeatable order. Photonic energy from each LED is reflected off an entity and is incident upon the sensor(s). Circuitry samples or acquires signaling from the sensor(s) in accordance with the respective LED activations. Signaling from the densitometer can be used in controlling ink-jetting printers or other apparatus.
    Type: Grant
    Filed: January 31, 2013
    Date of Patent: December 2, 2014
    Assignee: Hewlett-Packard Development Company, L.P.

  • Publication number: 20140022297
    Abstract: The invention relates to a fluid ejection system comprising a print head unit including a fluid ejection nozzle array, wherein the fluid ejection nozzle array comprises at least a first set of nozzles having nozzles of a first fluid ejection capacity and a second set of nozzles having nozzles of a second fluid ejection capacity and nozzles of a third fluid ejection capacity, wherein the first fluid ejection capacity, the second fluid ejection capacity and the third fluid ejection capacity are different from one another, and further including a printer controller which, in a first printing mode, selects nozzles of the first and second sets for firing in proportions so that the overall color densities generated by the nozzles of second set when compared to nozzles of the first set are the same in a defined print area.

  • Patent number: 8452195
    Abstract: A printing device configured to print a diagnostic plot, the diagnostic plot including a cockle pattern, a main media advance pattern, and a secondary media advance pattern, wherein the cockle pattern, main media advance pattern, and secondary media advance pattern are for providing feedback and for adjusting printing characteristics associated with the printing device. A method of adjusting vacuum levels in a vacuum system of a printing device including generating a diagnostic plot on media; the diagnostic plot including a cockle pattern, a main media advance pattern, and a secondary media advance pattern, and accepting adjustments to printing parameters on the printing device based on printing defects displayed on the diagnostic plot.
