Publication number: 20240101260Abstract: A device and method for detecting a phase transition between a liquid phase and a solid phase of a substance include a pair of electrodes, a sensing layer arranged in an electrical path between the pair of electrodes, and means for measuring a first electrical characteristic of the electrical path. The sensing layer includes a mixed ion and electron conducting composite material. The composite material has an electrical property, in particular electrical resistance, which shows a peak variation as a function of time at the phase transition, such as an onset of ice formation. Computing means process the first electrical characteristic to indicate an occurrence of the phase transition.Type: ApplicationFiled: January 27, 2022Publication date: March 28, 2024Inventors: Carlo Saverio IORIO, Patrice Désiré DONGO, Patrick QUEECKERS, Dario FARINA, Simone FABIANO, Xavier CRISPIN, Anna HAKANSSON

Patent number: 11818317Abstract: Certain examples relate to a method of printing management. An image is received for printing and printing parameters to print the image are determined. The image is printed onto a substrate using the printing parameters, and the image is printed with an embedded code corresponding to the printing parameters. The printing parameters are associated with the embedded code such that the printing parameters are retrievable from the embedded code.Type: GrantFiled: June 13, 2019Date of Patent: November 14, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: Peter Morovic, Jan Morovic, Xavier Farina Vargas, Jordi Arnabat Benedicto, Alessandro Beltrami

Publication number: 20230239420Abstract: Certain examples described herein relate to the control of colorants and treatments for printing. In certain examples image data, a colorant color mapping and one or more treatment color mappings is obtained. The colorant color mapping may be used to map the image data to colorant application values. The one or more treatment color mappings may be used to map the image data to treatment application values. The colorant application values and treatment application values may be used to generate discrete print control instructions to apply the set of colorants and set of treatments to a printing substrate.Type: ApplicationFiled: May 22, 2020Publication date: July 27, 2023Applicant: Hewlett-Packard Development Company, L.P.Inventors: Peter MOROVIC, Jan MOROVIC, Joan VIDAL FORTIA, Xavier FARINA VARGAS, Sergio ETCHEBEHERE JUAN, Hector GOMEZ MINANO

Publication number: 20220368812Abstract: A method is disclosed. According to some examples, the method comprises determining, by processing circuitry, a first element set to be associated with a print addressable location, the first element set comprising a first plurality of elements, wherein each element of the first plurality of elements identifies a print colorant or print colorant combination and is associated with a probability that the print colorant or print colorant combination identified by that element is to be applied to the associated print addressable location.Type: ApplicationFiled: November 18, 2019Publication date: November 17, 2022Inventors: Peter MOROVIC, Jan MOROVIC, Alessandro BELTRAMI, Sergio ETCHEBEHERE JUAN, Xavier FARINA VARGAS, Hector GOMEZ MINANO, Joan VIDAL FORTIA

Patent number: 10691988Abstract: Example methods of controlling printing of a halftone image are disclosed as well as apparatuses and computer-readable storage mediums relating thereto. In an example, the method includes receiving input data indicating a first colorant deposition order for a colorant combination and a second colorant deposition order for the colorant combination, wherein the second colorant deposition order is different from the first colorant deposition order. Control data is generated based on the input data. The control data includes first pixel data associating a first pixel in the halftone image with the first colorant deposition order, and second pixel data associating a second pixel in the halftone image with the second colorant deposition order. The control data is used to control a printer to print the halftone.Type: GrantFiled: September 30, 2016Date of Patent: June 23, 2020Assignee: Hewlett-Packard Development Company, L.P.Inventors: Peter Morovic, Jan Morovic, Xavier Farina Vargas

Patent number: 10226924Abstract: A printer for printing on a print medium as said print medium advances through a print zone, the printer including a number of print heads extending over the print zone, each print head including at least one nozzle array wherein at least two adjacent nozzle arrays overlap forming at least one stitching zone in the overlap region; and a printer controller for generating a sequence of nozzle firing commands for each nozzle array to selectively deposit droplets of print fluid on said print medium from said nozzle arrays in accordance with an image to be printed, wherein the printer controller further applies masks having decorrelated patterns to said sequence of firing commands for at least those overlapping nozzles of the nozzle arrays coinciding with the at least one stitching zone to obtain a predetermined optical parameter of the printed image in the stitching zone, irrespective of an offset between two adjacent nozzle arrays.Type: GrantFiled: November 13, 2014Date of Patent: March 12, 2019Assignee: Hewlett-Packard Development Company, L.P.Inventors: Leticia Rubio, Utpal Sarkar, M.

Patent number: 10000080Abstract: Example implementations relate to random wave mask generation. Some examples may distribute data points in a mask area based on a probability density function. The probability density function may have a maximum probability density located at a first edge and a second edge of the mask area. Some examples may also identify a wave curve that fits the data points. The wave curve may include oscillating waveforms of varying amplitudes. Some examples may also generate a random wave mask based on the wave curve.Type: GrantFiled: April 17, 2015Date of Patent: June 19, 2018Assignee: Hewlett-Packard Development Company, L.P.Inventors: Xavier Farina Vargas, M.

Patent number: 9936104Abstract: Certain methods and systems are described to provide color modelling. This color modelling applies to halftone images. In one example, a correction parameter for a color model is determined by minimizing a distance metric between a set of estimated spectral reflectance values and a set of measured spectral reflectance values to generate a multi-dimensional correction parameter. This enables a color model to be used to map at least one Neugebauer Primary area coverage value to at least one spectral reflectance value.Type: GrantFiled: January 30, 2014Date of Patent: April 3, 2018Assignee: Hewlett-Packard Development Company, L.P.Inventors: Peter Morovic, Jan Morovic, Xavier Farina Vargas, Juan Manuel Garcia Reyero Viñas

Patent number: 9895915Abstract: Example implementations relate to swath height error compensation. Some examples may determine a density of an image to be printed in an overlap area of a printing material. The overlap area may include target pixels capable of being printed by a first set of drop ejection elements and a second set of drop ejection elements that are redundant to the first set of drop ejection elements. Some implementations may also determine a mask to apply to the first and second set of drop ejection elements based on the determined density, and the mask may designate at least one additional drop to apply to at least one target pixel in the overlap area by at least one of the first and second set of drop ejection elements. Some implementations may also apply the mask to the first set of drop ejection elements and the second set of drop ejection elements.Type: GrantFiled: August 10, 2017Date of Patent: February 20, 2018Assignee: Hewlett-Packard Development Company, L.P.Inventors: M.
