Patent number: 10434725Abstract: An example method for constructing a three-dimensional object in accordance with aspects of the present disclosure includes projecting an image of a section of a three-dimensional object on a building plane through a projection unit, forming a cured section by irradiating laterally an interface of a photopolymerizable material on the building plane with light corresponding to the image of the section of the three-dimensional object, moving a support plane laterally to detach the cured section from the building plane resulting in a gap between the cured section and the building plane, and filling the gap between the cured section and the building plane with photopolymerizable material.Type: GrantFiled: April 30, 2013Date of Patent: October 8, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Alejandro Manuel De Pena Hempel, Ramon Vega Ainsa, Xavier Bruch Pla

Patent number: 8057010Abstract: A method of printing an image on a substrate using a page-wide-array printer and a page wide array printer is provided. The method includes printing a first portion of the image as relative movement occurs between the substrate and the print heads, and printing a second portion of the image as relative movement occurs between the substrate and the print heads, such that there exists an area of overlap between the first portion of the image and the second portion of the image. The substrate may be moved in a first direction relative to the print heads whilst the first portion of the image is printed, moved in a second direction opposite to the first direction; and moved in the first direction again whilst the second portion of the image is printed. The substrate may be printed whilst the substrate is moved in the second direction.Type: GrantFiled: September 29, 2008Date of Patent: November 15, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Sergio Puigardeu, Alex Andrea, David Gaston, Joan Joroa, Angel Martinez, Silvia Miramanda, Ramon Vega, Jordi Sender, Marti Rius

Patent number: 7995188Abstract: The invention relates to a method of estimating a distance to a surface, whereby an emitter emits light towards a surface, at least some light being reflected by the surface, the surface comprising a detectable feature, the reflected light being received by a first receptor and by a second receptor, the surface being in movement relative to the receptors, the first and the second receptor receiving the light reflected at a first and at a respectively second angle thereby producing a first and a respectively second dataset, each dataset including data representing said feature, the first and the second angle being different, whereby the distance is estimated using the first and the second dataset.Type: GrantFiled: July 15, 2005Date of Patent: August 9, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Jordi Ferran, Xavier Soler, Ramon Vega

Patent number: 7866788Abstract: A method of printing on a substrate and a printer are provided. The method uses a printer comprising a print head and a mask having a hole therethrough, the mask being disposed between the print head and the substrate, and comprises aligning the hole with the print head; printing on the substrate through the hole; and misaligning the hole with the print head so that the print head is covered by the mask. The method may allow the servicing of a print head in the array while the printer is printing on the substrate using at least one of the remainder of the print heads in the array.Type: GrantFiled: October 3, 2008Date of Patent: January 11, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Joan Jorba, Sergio Puigardeu, Jordi Sender, Alex Andrea, Silvia Miramanda, Angel Martinez, David Gaston, Ramon Vega, Marti Rius

Patent number: 7866779Abstract: Printing is performed at a full resolution using a first set of nozzles and a second set of nozzles arranged on a printhead. Printing is performed at less than the full resolution using the first set of nozzles less any nozzles in the first set of nozzles that have been determined to be defective. The second set of nozzles is not used for printing at less than the full resolution except for a subset of nozzles in the second set of nozzles that are used to replace nozzles from the first set of nozzles that have been determined to be defective.Type: GrantFiled: October 1, 2008Date of Patent: January 11, 2011Assignee: Hewlett-Packard Development Company, L.P.Inventors: Angel Martinez, Alex Andrea, David Gaston, Joan Jorba, Silvia Miramanda, Sergio Puigardeu, Marti Rius, Jordi Sender, Ramon Vega

Publication number: 20100277525Abstract: A method of printing on a substrate in a page-wide array printer comprises printing on the substrate as the substrate is moved through a printing zone of the printer in a first direction, and printing on the substrate as the substrate is moved through the printing zone in a second direction different to the first direction.Type: ApplicationFiled: November 16, 2007Publication date: November 4, 2010Inventors: Jordi Sender, Alex Andrea, Ramon Vega, David Gaston, Joan Jorba, Silvia Miramanda, Sergio Puigardeu, Marti Rius, Angel Martinez

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: 7261388Abstract: In a method of printing a plurality of pages during a print job, a page-wide-array printing device having redundant dot-forming elements is used. Print masks distribute dot-forming-element activity between the redundant dot-forming elements in a manner taking into account known malfunctions of dot-forming elements to hide such malfunctions, or reduce a visible effect of such malfunctions in the pages printed. The method includes generating a plurality of print masks which are different, as they distribute the dot-forming-element activity in different ways, but are equivalent, since they are based on the same knowledge of dot-forming-element malfunctions; dividing the print job into page-sets of at least one page; and printing the different page-sets of the print job using different equivalent print masks, thereby distributing the dot-forming-element activity in different ways from page-set to page-set.Type: GrantFiled: February 28, 2005Date of Patent: August 28, 2007Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ramon Vega, Jose Luis Valero, Xavier Bruch
