Patent number: 8136910Abstract: The invention relates to a calibration method for a printer having a mechanism for advancing a medium in a direction of media advance comprising the following steps: (a) providing a printhead, the printhead having a swath height in the direction of media advance; (b) providing an estimate of either the swath height or the characteristic of the mechanism; (c) printing a base pattern on a medium using the printhead; (d) printing an overlay pattern on the medium using the printhead to form an interference pattern; (e) advance the medium of a predetermined distance using the mechanism at a time between the printing of the base pattern and the printing of the overlay pattern; (f) analyze an optical evaluation of the interference pattern; (g) evaluate as either: (i) the swath height if the characteristic of the mechanism is known or estimated; or (ii) the characteristic of the mechanism if the swath height is known or estimated.Type: GrantFiled: June 7, 2006Date of Patent: March 20, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventors: Pasqual Batalla, Jordi Sender, Marc Bautista, Toni Gracia, Angel Alvarez, Jean Frederic Plante, Alex Andrea, Pascal Ruiz, Joan Campderros, Angel Martinez Barambio, Alejandro Campillo, Marcos Casaldaliga

Patent number: 6983218Abstract: A method of determining an angle between a first direction of movement of a print head and a second direction of movement of a print media, comprises: printing an array of markings on said print media, said array of markings extending along said first direction and along said second direction; traversing a sensor device along said first direction, and detecting a signal corresponding to said plurality of markings; identifying a plurality of peaks in said sensor signal as a plurality of data co-ordinates; and obtaining an angle data describing an angle between said plurality of data co-ordinates and a reference data.Type: GrantFiled: October 20, 2003Date of Patent: January 3, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Pascal Ruiz, David Toussaint, Marc Serra

Publication number: 20040037315Abstract: The invention relates to the transmission of autonomous executable code and/or of associated data in a network. It includes the placing into bitstream form of the executable code C (stage T2) and of the associated data D (stage T3) of a mobile agent A before converting them into a bitstream to be sent fA (stage T4). After the conventional digital processing operations on reception (stages R1 to R5), the receiving node NR receiving this stream fA extracts the code C and the parameters D (stages R8 and R9). The code C is run autonomously (stage E2) then the code C and its runtime context (associated parameters and resulting data) are again converted into a bitstream fA transmitted to the next node (stages T). The final node recovers the data DR resulting from the running of the code C on the nodes N of the route P (stage R11).Type: ApplicationFiled: December 20, 2002Publication date: February 26, 2004Inventors: Antoine Delautre, Sebastien Gillardeau, Pascal Ruiz
