Patent number: 9994036Abstract: An example in accordance with an aspect of the present disclosure includes an ink channel of a printer, coupleable to an ink supply to receive an ink. A sensor assembly is mounted to the ink channel, including a sensor in fluid communication with the ink channel to identify an ink level of the ink supply based on a pressure difference between an air pressure, associated with the sensor assembly, and an ink pressure, associated with the ink channel.Type: GrantFiled: February 4, 2014Date of Patent: June 12, 2018Assignee: Hewlett-Packard Development Company, L.P.Inventors: Emilio Angulo Navarro, Fernando Bayona Alcolea, Jorge Castano Aspas, Mikel Zuza Irurueta, Alfonso Cameno Salinas, Albert Crespi Serrano

Publication number: 20170182786Abstract: An example device in accordance with an aspect of the present disclosure includes a sensor die having a sensitive region and a bond pad. A bond is formed between a wire and the bond pad of the sensor die. An encapsulant is to retain the wire at the bond pad and mechanically support the wire and the bond, based on covering the bond and wire according to an encapsulant height, extending from the bond pad, greater than a bond height. The encapsulant is localized at the bond pad of the sensor die to enable the sensitive region to remain uncovered by the encapsulant.Type: ApplicationFiled: February 4, 2014Publication date: June 29, 2017Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, LP.Inventors: Emilio Angulo Navarro, Josiah CHAN, Fernando Bayona Alcolea, Albert Crespi Serrano, Mikel Zuza Irurueta, Jorge Castano, Ying Ying HO

Patent number: 7677716Abstract: Ejected liquid forms a latent image on a charged transfer surface. In some invention aspects electrostatic charge is first applied to the surface; inkjet devices eject the image-forming liquid; voltage is established between the devices and surface; another, separate substance associated with the latent image actuates it. In other aspects hydrophobic or hydrophilic material in the surface stabilizes the image on it; electrostatic apparatus, associated with the surface, cooperates with the stabilizing material, further controlling image-droplet position and size. In other aspects a desired image forms on a final printing medium, based on an input electronic image-data array; the liquid ejection is onto an intermediate transfer surface, based on detailed incremental control by the data, forming a latent image representing the desired image.Type: GrantFiled: January 26, 2005Date of Patent: March 16, 2010Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ramon Vega, Jordi Ferran, Eduardo Martin, Emilio Angulo, Jorge Castano, Pedro Luis Las Heras

Patent number: 7156482Abstract: PPS variation along a scan axis is found by shining a light beam from pen carriage to print-medium position and back to detector, and applying a pathlength/intensity correlation. Sensing is done while scanning, to find relative PPS profile along the track. With no medium in place this measures mechanical imperfections—and can be corrected by later deducting thickness of a medium. If medium is present, adjustment is omitted. For absolute values a plural-lamp sensor is calibrated for each lamp, at the PPS design point. Pagewide/webwide variants are included.Type: GrantFiled: August 28, 2001Date of Patent: January 2, 2007Assignee: Hewlett Packard Development Company, L.

Patent number: 7014295Abstract: The present invention is embodied in a system and method for producing efficient ink drop overlap filled with a pseudo hexagonal grid pattern. In general, the present invention can include an inkjet printhead assembly that incorporates a preprogrammed correction scheme or schemes [1-n] (herein correction scheme will refer to all applications), for correcting systematic ink drop placement errors of the inkjet printhead. The printing system of the present invention uses a unique ink dot pattern, called a pseudo-hexagonal close pack system. The present invention optimizes the addressable grid for dot placement, pseudo hexagonal close pack system, with an efficient geometry for packing circles to fill an area, similar to the hexagonal close pack system. However, the present invention in creating dots on a non-symmetric grid is supported by available software and is not computationally complex.Type: GrantFiled: November 15, 2003Date of Patent: March 21, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Mark S. Hickman, Wayne M. Richard, Jorge Castano, John A. Underwood, Xavier Bruch

Publication number: 20040196325Abstract: A method of determining a registration offset in a hard copy apparatus, the apparatus comprising a pen arranged to mark a print medium and a sensor arranged to detect marks on the medium along a sensor path, the method comprising the steps of: marking a alignment pattern on the medium, the pattern being at least partially located along the sensor path; detecting the position along the sensor path of a portion of the pattern; and, determining a distance by which the pattern is offset from the sensor path in a direction substantially perpendicular to the sensor path, the pattern being configured such that the detected position is indicative of the offset distance.Type: ApplicationFiled: April 23, 2004Publication date: October 7, 2004Applicant: Hewlett-Packard CompanyInventors: Jorge Castano, David Toussaint

Patent number: 6623096Abstract: An optical sensor for detecting the position of marks on a medium, wherein relative motion is provided between the optical sensor and the medium during an optical sensing operation. The optical sensor produces an electrical sensor signal, and has a field of view at the media in a direction of the relative movement. The marks have a nominal dimension in the direction of the relative movement, and the field of view is larger than the nominal dimension. This produces a sensor signal with a clear and relatively sharp peak in response to scanning the media mark.Type: GrantFiled: July 28, 2000Date of Patent: September 23, 2003Assignee: Hewlett-Packard CompanyInventors: Jorge Castano, Francesc Subirada

Patent number: 6595621Abstract: An ink jet printing process for removing or substantially hiding vertical bands which may be produced during a printing operation includes the application of a controlled variance to shift the horizontal position of certain ink drops fired from certain nozzles. That is, instead of firing ink drops from each of the nozzles simultaneously, the controlled variance causes the ink drops to be fired at various times after the firing signal has been received. The controlled variance may involve a mathematical formula applied to set the level of horizontal shift for each of the ink drops. Examples of suitable mathematical formulae include sinusoidal functions, Bessel functions, and Tschebysheff polynomials.Type: GrantFiled: June 4, 2001Date of Patent: July 22, 2003Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jorge Castano, Xavier Girones
